Newly developed 1-motor hybrid transmission used for Toyota’s new Crown
BluE Nexus, AISIN and DENSO have jointly developed a new 1-motor hybrid transmission. The 1-motor hybrid transmission developed by the three companies integrates the newly designed Direct Shift-6AT with a driving motor and an inverter. It is characterized by high acceleration performance and contributes to increasing fuel efficiency. In combination with the eAxle mounted at the rear of the vehicle, the 1-motor hybrid transmission achieves driving performance suitable for the premium vehicle by taking full advantage of the 2.4 L turbo engine, contributing to enhancing the attractiveness of Toyota’s new Crown.
The quick response to start the vehicle moving forward has been attained by using a newly developed highly heat-resistant starting clutch and achieving advanced control. The high-torque assist effect is demonstrated due to a newly designed driving motor combined with the Direct Shift-6AT, realizing direct response and torqueful driving. Toyota’s new Crown CROSSOVER RS will be launched around the fall of this year.
The clutches for starting the vehicle moving forward and disengaging the engine are subject to coordinated control so that the engine can be started and stopped smoothly and quietly when starting the vehicle moving forward and in all situations during driving. The new 1-motor hybrid transmission achieves both direct response and smoothness and contributes to realizing the high-quality ride suitable for the premium vehicle by combining the latest technologies with world-class automatic transmission gear shift technology, which has been refined over many years.
