System Description

The active engine control function can be turned ON/OFF by operating the steering switch.

CORNERING CONTROL

For the purpose of reducing the operation of switching to depress the brake pedal during cornering, the operation information of the driver is computed by the chassis control module and a command is transmitted to TCM.

Based on the command from the chassis control module, TCM shifts the gear ratio of the transaxle to the low side and applies the engine brake.

The transaxle is controlled according to the steering operation of the driver as well as the accelerator pedal condition and cornering condition of the vehicle.

BRAKING CONTROL

For the purpose of improving the feeling of effectiveness of the brake when decelerating, the brake operation amount of the driver is computed by the chassis control module and a command is transmitted to TCM.

Based on the command from the chassis control module, TCM shifts the gear ratio of the transaxle to the low side and applies the engine brake.
