  • A Toyota Master Diagnostic Technician explains in simple terms how the inverter with converter assembly work in Toyota Hybrids.
    In this brand new series I will go over all components of the hybrid system explaining their basic function in a simple way that's easy to understand. The theme of this series is simple but complicated.
    The hybrid system in Toyota cars is super complicated and a marvel of engineering. In this series I try to keep things simple and light so Toyota Hybrid owners can see how their cars work.
    I believe if you know how your car works you'll be able to utilize all it's features better and better understand your hybrid Toyota.
    In this part of the series I will be explaining the commonly misunderstood B mode. Does it help charge your battery faster? What actually happens when you put your Toyota Hybrid in B-Mode? Also I will be covering Toyota Hybrid all wheel drive AWD system. And how Toyota hybrids don't have transfer cases and drive shaft.

    I rented a Prius in California and was visiting a friend who lives in a very hilly neighborhood and the street she lives on is very steep. I tried B mode when going down that hill and it made a significant difference in helping to control the speed of the car. It took a big load off the brakes.

    Yet another VERY informative video! Fills in the blanks that the humongous Toyota handbooks leave out! My UK 2018 Gen 4 RAV4 AWD doesn't have B mode but does have S+/- but the dealer never explained properly what this option is for. I live out in very rural Scotland & our hilly single-track road out to the main road never gets gritted despite frequent snow. Prior to the Toyota I was very capable and happy to drive front wheel drive cars with "all season" tyres in the snow - the RAV is my first automatic car and I do have reservations (ok - scared almost!) about driving it on snowy slopes despite it being AWD given that I believed I couldn't control the engine braking/gearing like on a front wheel drive car. So now I know - use the "manual" S+/- mode to get the necessary engine "braking" effect for these snowy, hilly roads - thank you!

    As a fellow Illinoisian, I don't think there's anywhere in this state that we'd really need B Mode. However, if we take a road trip up Pikes Peak, we'll need it on the way back down!

  • @rockymountainjazzfan1822
    @rockymountainjazzfan1822 Před 2 lety +7

    I regularly drove a 2013 Prius on steep mountain grades, including one that descended 2,000 ft. in elevation in 12 miles. "B" mode definitely works on steep grades such as that. One note though: when the Prius first starts descending a steep mountain grade, as the video noted, putting the gear shift in "B" mode will put the hybrid system in full regenerative braking. For awhile, however, the gasoline engine may only run at idle RPM--until the hybrid battery reaches full charge. Then, the gasoline engine will be revved up to provide engine braking--presumably because the hybrid system can no longer use full regenerative braking because it would overcharge the hybrid battery. By the way, the proof that the hybrid system does greatly improve fuel economy is that my Prius gets about the same fuel economy traveling up and down steep mountain grades as it does traveling on a flat highway. The things that ding the fuel economy of my Prius the most are driving in very hot or very cold weather, or using the A/C a lot.

    Thanks so much for this series. I am in Australia and have purchased an imported Japanese model 2007 Toyota Estima Hybrid AWD. (I think you might know this as Previa.) All the glovebox books are in Japanese and Australian Toyota dealers know very little as this car wasn't sold here.
    You have answered so many questions for me and I feel somewhat more comfortable to talk to mechanics about maintenance jobs while getting it approved for Ride-Share registration (Taxi standard) as required in my state.
    I have started giving my husband and son tips from your other videos for their cars too. I killed my last Toyota (2001Tarago/Previa) from getting poor advice. That is not happening again.

  • @ronaldmail00
    @ronaldmail00 Před 3 lety +3

    Bravo. Ty for your hard work. Alot of folks figured it was putting on full regen. Noticed that the engine would come on sometimes but not always. I personally figured if the battery was in a low state of charge it just throws it into the battery. If it gets too full or hot/overheated, it burns off the excess with the engine.
    I imagine the advice of leaving it in Brake mode stems from the Chevy Volt guys doing it. They have a huge battery in comparison to other hybrids so they are almost always able to accept all that extra electricity into the battery. But also, when their battery is full (say they just left their house with a full charge) their engine would rev up to burn the extra electricity as well. I'm not sure if the Prius Prime works that way, but it might.
    You are definitely right tho it would put alot of extra strain on the generator and engine that usually the friction brakes would take the strain of. Besides, should use them friction brakes when ya can, we get so much rust caking up on them cause we hardly use them 😝. JK but true lol.

    Car Care Nut,
    we just got our car delivered this friday, the last Prius Wagon + in Belgium (Europe). The dealer was a big let down. The luggage cover was missing and it took five minutes to convince him that it has to be there. The window control on the drivers side isn't working. We noticed this when already on the road....
    Thank you for being very clear about the B-mode. That is something I can take off my list :). I will look for more of your video's. Thanks.
    It is a great car thou.

  • @sedatnet
    @sedatnet Před 3 lety +4

    Another very informative video, thanks. 2 interesting observations from my corolla:1-during long downhill driving in D mode, after a while I feel the system runs as if in B mode. Engine starts and runs at high rpms like in B mode. Probobly for people who do not use B mode, preventing breaks overheat. The 2nd observation: in B mode downhill driving, if you push throttle pedal, you will see your rpm of the engine will decrease. :). Push throttle for lower rpm.. :)

    • @TheCarCareNut
      @TheCarCareNut  Před 3 lety +9

      Thank you for watching my video! Very awesome observations! So the newer hybrids have the ability to pick up when it’s going down hill automatically and will try to help the brakes automatically. Also the reason the rpm goes down is the car decreasing the effect of b mode as an acceleration method.

  • @jongonegone1262
    @jongonegone1262 Před 3 lety +8

    so b mode is a break pad saver on big down slope hills, while helping to keep brake pads cooler and helps keep them from burning up while maintaining a safe speed down hill. so the owners manual should say to only use b mode when needed traveling on steep downgrades. very well done video. thank you. word of caution : dont have 7 adults and a rv trailer in tow going down a large steep hill with your prius, or youll be paying this guys toyota dealer tech an extra 8 car payments while you sit in the waiting room, bring your tent and sleeping bag, youll be camping out at the toyota dealer campground. sir did you happen to see the brake pads in your rear view mirror ? no sir mr. tech------- the smoke was to thick.

    • @rubdulbah3201
      @rubdulbah3201 Před 3 lety

      Maybe that is just "Sport" which makes the car accelerate easier and gives you full control of the paddle shifters.

    • @FanRailer
      @FanRailer Před 2 lety +1

      As I understand it, S mode on the newer hybrid models is B mode, but with selectable levels of electric braking. The “lower” the gear you select in S mode, the faster MG1 spins the engine, and the more electric braking force is provided.

    I'm a big fan, you have taught me so much useful info. I am giving my 2012 XLE Camry Hybrid (150,000) mile and ZERO problems with std maintenance to my daughter. I am waiting for delivery of my 2023 RAV4 Premium Hybrid so I really want to understand everything I can and you have supplied me with details I could not easily find.
    OK so this B-mode lesson has me a bit confused. Under normal braking the engine stops and the both the wheels and MG2 are directly attached to the ring gear all of which spin with the inertial force of the wheels applying input to MG2 and its reactionary drag to the wheels - as you say life is good (I understand)
    B mode still has me scratching my head. Going downhill foot off the accelerator, MG2 still providing (insufficient) braking force so the engine is off but directly attached to the planetary gears and these are now spinning the engine too as an additional input force from the wheels thus supplying more engine braking force to augment MG2 braking force alone???? Why do we need HVB energy to spin the engine by way of MG1, this would negate engine braking. MG1 is attached to the sun gear. Why cant the ring, planets, and sun all be turning at once supplying even more braking by way of MG1 charging (not depleting the HVB)
    Its confusing but this is how I would imagine it might work. I cannot account for the direction of spin with each all of them turning. Perhaps MG1 needs HVB energy simply to hold the sun gear stationary in order for the ring to supply all of its force to the planets (and its attached engine) ???
    I'm still confused.

      1. How well will the hybrid AWD in mild off roading?
      2. In the event there is a problem with the hybrid AWD front drive, how well will the hybrid AWD "Rear Drive" perform to get the vehicle home or to a repair facility? You've got my attention with the AWD Rear Drive (MGR and running gear) as part of a 4WD system, possible selectable rear drive, possible emergency drive system, also what kind of and how much torque/horsepower does this rear drive MGR produce?
      All of a sudden I can see potential possibilities especially in the aftermarket on road and off road driving! HHMMMMMMM!

    Love your videos. By the way, you have a beautiful speaking voice. Your diction is perfect and every word is precise. Now that I have buttered you up, my wife's car bought new is an '18 RAV4 hybrid XLE and love it. I am a low tech guide and since we have owned it I have never used any gear except P R N and D. Never opened the sunroof, don't use bluetooth, voice commands, etc.but have the enhanced radio because I needed the built in NAV system. Believe me folks don't read the owner's manual. To boring. Heck the stereo system manual is over 300 pages so anyway I am looking how to turn on the heated outside mirrors and never could figure it out so I laboriously went through the owner's manual until I found it.(not easy) WaLa! If you turn on the rear windown defroster the heated mirrors come on. Who knew and what a stupid thing to do.Anyway I have a question for you. I wanted the additional Toyota side steps to help us get in and out but the Toyota dealer was unable to find them in the parts computer but listed for non hybrid models. Can you tell me why? thanks, and what great videos.

If that's the case then this allows you to drive the car full electric for a very short distance at lower speeds. Basically you can use that in slow traffic to save gas.

      @@TheCarCareNut Thanks for the info. The VIN is JTMRJREV1JD168477. The Toyota parts guy speculates that where the attachment hangers go underneath they could interfere with the hybrid differences in the under carriage. Again just his opinion and he even called someone (don't knew who) and they couldn't come up with the sidestep part number. I don't want to use an aftermarket step(s) because he said it could void the warranty if they modify something. That was his advice.

    On my Toyota RAV4 (2018), which was manufactured in Japan and is driven in the UK, I don't have a "B" gear but I do have "S" to manually control gear selection. However, I've found a good way of controlling my speed when going down long hills (of which there are many in South Wales here in the UK) is to simply put the car into cruise control mode and set the speed to, say, 40 mph. I find that the car maintains that speed going both down and up hill, deviating only when I get too close to the car in front, at which point it slows down and speeds back up to 40 when the car in front is far enough away. It saves me having to constantly monitor the speed as the car does it all for me until I apply the foot brake.

    Thanks great advices yeah just for testing b mode does waste more gas in my experience when going flat road and not a downhill but I wanted to tested and it does charge battery faster but you waste more gas power cause the car feels heavier due to the resistance on gen1 . I wonder why on gen2 you can go 1-10 mph background on Ev mode” pure electric and sometimes gas engine kicks in but it’s rare yet on forward pass 4 /5 mph the gas engine kicks in .

    I've noticed that when I use B mode to descend hills and then take it out of B, using brakes instead, the display shows much more regeneration using the brakes. Also (on my 3rd gen 2014) if I put it into B mode just driving around it won't go into ECO mode, at least with the type of driving I do.

  • @petershen1984
    @petershen1984 Před 2 lety

    It's Really smart! So regen is playing the role of engine braking and half the work of the friction disk brakes. It fills the battery with charge and then spins the engine to make room for further regen braking.

    @ronkemperful Před 2 lety +1

    Great explanation of “B” mode. One question is under extreme conditions, after completely draining the hybrid battery (as far as the computer allows) by going up a steep mountain grade, will the battery possibly be too warm to accept full regenerative braking? I was descending down Pike’s Peak and I had to ride the hydraulic brakes, even though I was using the B mode at 15 mph; and the display showed no interaction between the engine and the battery. As a result, at the brake temperature checking station, I had to pull over for 20 minutes for brake cooling. I don’t know how I could have done anything differently to prevent possibly losing my brakes.

    How do you use B mode. When do you use it? Do you use it to break while you're driving. Do you shift while you're driving into B mode? Do you shift into it. Let your battery charge. Then turn it off? I just got a 2013 Prius Persona. I took auto tech. I am lost right now. I love you're channel though. You're the reason I bought my Prius. Love n Respect brother

    • @smoguli
      @smoguli Před rokem +1

      B mode is like downshifting your transmission, it gives engine braking so use it when going downhill just like shifting an automatic to 3 or 2 instead of D. You can shift to B while driving at any speed, it won't hurt anything. Don't drive in B mode all the time because it's ineficient and you fuel economy will be worse.

    Eureka! This all makes sense. Yesterday I drove up to the Kitt National Observatory. It's a 12 mile drive up from 2K to 7K ft altitude. My 2117 Prius performed flawlessly going up, 25 to 30 mph. Coming down I thought I'd try the B Mode. (I didn't recall exactly what it was for.) I immediately felt the car feeling resistance. It was an off day so there were no other cars on the road, good. I moved along 20-25 mph and then I heard the engine spin up...gasp! Was this good or not? I kind of freaked and a few times I slowed and put it in D letting the speed go up to 30. I had no issues on the drive down partly because I was white knuckle driving being more concerned with not going over the side of the mountain! 8-] Hello?
    Now I know that when the engine spun up it was being lubricated with oil and no fuel was being pumped into the cyclinders. Whew! The system was functioning exactly as it was designed. Thank you CCN! Now when I got back down from the mountain it was HOT (Which was why I went up the mountain in the first place, 85! versus 100+).
    This brings up another concern. It's mid June and it's getting hot. (It was 112 when I got home, summer is spinning up) I have made it a point to have the AC set to circulate throughout the entire car, not just focusing on the driver. I specifically set the passender dash vent to focus airflow downward along the door towards the back floor board where the fan intake to the HV battery is located. I also make sure there is nothing on the back floorboard that could affect the air flow. (I replaced the filter also) I'm thinking this will help a bit and it certainly won't hurt. I just seems reasonable. Summers in Tucson are brutal and when you see a roadrunner carrying a canteen you should give it some thought.
    Thank you CCN, it's now very clear how B mode works. I bought my 2017 Prius about a year ago from the dealer about a mile from my place. It was Certified "Pre-owned", had 60K miles, was clean and in beautiful condition. It was from your videos that I learned much more about how the Prius hybrid functions. Mine has functioned flawlessly and I enjoy driving it. You are a gold mine of information, thank you, thank you, thank you.

  • @raultorrellas4512
    @raultorrellas4512 Před 3 lety +47

    Actually, the toyota cars automatically put themselves in "B mode" when they detect a descending slope and you let off the acceleration pedal, especially if you have cruise control activated. The car engages the motor and tries to maintain speed without applying the brakes.
    Actual B mode is almost never needed because of this, since the car automatically uses the engine to brake in D mode. I have only used B mode in mountain descents through slow speed roads, that's the only situation when I found it to be useful, other than that the normal D mode is enough.

      @@scoschegn When I say they go into "B mode" it's not actually changing the mode, it just engages the motor with no ignition so it helps braking the car without overworking the batteries when descending. Should be normal behavior to prevent battery overheating in all "hibryd synergy drive" cars, but 2006 highlander is petrol so that's out of the scope here.

      The battery does not charge at all while the shifter is in "N" position. You probably know this, but the position the shifter always springs back to is not "N." Maybe your Corolla has a more traditional shifter, unlike the Prius.

      Thank you for watching my video! So on your Lexus the paddle shifter is basically going to artificially vary the level of b mode to give the feel of manually shifting a transmission but it’s actually also b mode just the intensity is changed with the paddle shifters.
