Vehicle control

 The internal combustion engine and electric motor have different characteristics as shown in the figure below. The characteristics obtained by the combination of engine and transmission (torque converter) can be realized by the combination of inverter and electric motor.

Example of an electric microbus based on the use of the electric motor, inverter and ECU manufactured by Sawafuji Electric.


 An electric vehicle having such system has no shock caused by the shift change of transmission, providing a smooth acceleration.
