Batteries and electronic technology get a lot of attention concerning hybrid vehicles. The Toyota research and development department has been burning the candle and working hard at developing affordable Toyota transmissions for hybrids, which is only one reason they lead the competition in hybrid transmission innovation. Now General Motors, Daimler/Chrysler, and BMW are applying more mechanical engineering to catch up. The three manufacturers are combining efforts to develop a hybrid transmission technology to beat Toyota’s system.
A lot of Toyota success is due to the sophisticated control systems and sound mechanical engineering of the transmission in order to share power with the engine, electric drive motors, regenerative braking, and wheels. Always looking for areas to improve is one way they have outperformed top competitors.
Daimler and GM hybrids are coined ‘hybrid light’, providing limited boosts in fuel economy, BMW does not have a hybrid, yet.
Toyota’s hybrid transmission system is considerably different because its a power-splitting transmission. Competitors such as Honda have integrated electric power by adding motors to more-conventional transmissions, such as the Insight, which is one reason it costs a lot less than a Prius. As a result, a hybrid’s engine must be consuming fuel (operating) for the vehicle to move.
The opposing technology from Toyota enables the Prius sedan and the Highlander Sports Utility Vehicle to start off from a stop using the electric motors only, (thus the small gas engine is off) during the low-speed driving when the least benefits come from the gas motors. Thus, the engine only starts up only when the driver presses the accelerator pedal harder for more power than the electric motors can provide or to recharge the vehicle’s batteries. The internal combustion engine will sometimes start at a stop light if the A/C is on also.
Toyota hybrid transmissions also uses to their advantage its electric-vehicle (EV) mode to drive its hybrids in reverse, so there’s no need to have a built in planetary type reverse gear setup common to conventional automatic transmissions. In practice the electric motors simply reverse in direction. Since it is a CVT design, no gears are involved.
Certain hybrids have been on the road long enough to be out of warranty. Replacing your hybrid transmission is a very touchy subject. By now a few requests for replacement Toyota hybrid transmissions are rolling in.
After talking with the Toyota dealership about cost, and listening to the indecisiveness of many transmission mechanics, people are looking for better sources and options of hybrid transmissions for sale.
