This course explains in detail about the various optimization techniques adopted by Toyota in order to develop a lightweight and highly efficient hybrid transaxle.

• Comparison between Single axis Vs Dual Axis Motor Structure

• Optimization of the Motor Cooling structure for effective cooling and thermal management.

• Methodologies for reduced mechanical losses and highly efficient Power flow in the hybrid system

In addition to that, it explains about the various modes of operation of the Toyota Hybrid system. Also it helps to understand the energy management methodology adopted by the Hybrid system for different vehicle operating conditions.

• Effect of motor, battery and tires on the energy utilization of the hybrid powertrain system.

• Discussion on the simulation results of the various operating conditions with the battery state of charge.

• Understand the effect the ambient temperature on the operating characteristics of the engine and motor

The third module covers the various NVH (Noise, Vibration, Harshness) optimization techniques adopted by Toyota in order to develop a more silent hybrid transaxle and thereby improving the passenger comfort.

• Noise, vibration generation sources and mechanisms are also discussed for clear understanding of the background of the whine noises generated by the powertrain.

• Understand the effect of optimization of various components of the hybrid propulsion system on the improvement of the NVH behavior on the whole
