ACTIVE TRACE CONTROL FUNCTION

ACTIVE TRACE CONTROL FUNCTION : System Description

INFOID:0000000010329800

• Active trace control function controls the braking utilizing the ABS actuator and electric unit (control unit),

depending on cornering condition calculated from driver's steering input and plural sensors.

• Active trace control function is aimed to enhance traceability at corners and smooth the vehicle movement to

provide confident driving.

• When the ESP/VDC OFF switch is used to turn OFF the ESP/VDC system, the active trace control system is

also turned OFF.

• When the active trace control is operated, active trace control graphics are shown on the information display

of combination meter. These are shown only when “Chassis control” is selected on the information display.
Refer to 

MWI-17, "INFORMATION DISPLAY : System Description"

.

• When the active trace control is not functioning properly, the master warning lamp illuminates. Warning mes-

sage “Chassis control” will also appear on information display.

NOTE:
• The active trace control may not be effective depending on the driving condition. Always driving carefully and

attentively.

• Brake pedal may vibrate and brake pedal feel may change during active trace control operation. Also opera-

tion noise may be noticeable during operation. These are not abnormal conditions.

• When the active trace control is selected OFF, some functions will be kept ON to assist driver. (For example,

avoidance condition.)

SYSTEM

Active trace control helps enhance the transition from braking into
and then accelerating out of corners. Active trace control utilizes the
vehicle

s electrically-driven intelligent brake system to help improve

cornering feel by automatically applying brakes. Furthermore, Active
trace control will apply selective braking to help create increased
steering response in S-turns. For example, if driving through an S-
turn that starts with steering to the right, the right-side brakes are
engaged to create a yaw momentum and help turn the vehicle.

• Brake control amount is controlled according to steering operation status by the driver and vehicle cornering

status.

• During cornering, the brake control system limits changes in steer-

ing angle by controlling the inner ring brakes according to acceler-
ator pedal operation and allows smooth movement of the vehicle
to achieve stable cornering.
