• When performing quick lane changes, and other excessive steer-

ing operations, the brake is operated automatically, and erratic
vehicle behavior due to steering operation is reduced.

- The brake is controlled according to the steering operation condition of the driver and the cornering condition

of the vehicle.

ACTIVE ENGINE BRAKE FUNCTION

ACTIVE ENGINE BRAKE FUNCTION : System Description

INFOID:0000000010721692

• When the active engine brake (cornering control) function operates, operation display can be checked on

the information display in the combination meter. Refer to 

DAS-187, "INFORMATION DISPLAY (COMBINA-

TION METER) : Chassis Control Display"

.

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

MWI-71,

"INFORMATION DISPLAY : System Description"

.

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 with the chassis control module and a command is transmit-
ted 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.

Combination meter

Mainly transmits the following signals to chassis control module via CAN communication.
• Active trace control setting change request signal
Mainly receives the following signals from chassis control module via CAN communication.
• Curve display request signal
• Tire display request signal
• Active trace control setting display request signal
• Chassis control malfunction display request signal

Steering angle sensor

Mainly transmits the following signals to chassis control module via CAN communication.
• Steering angle sensor signal

[CHASSIS CONTROL]

SYSTEM

- 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.
