ACTIVE TRACE CONTROL (DYNAMIC CORNERING ENHANCEMENT) FUNCTION 
: System Description

INFOID:0000000010721691

• The steering operation condition by the driver and the information from multiple sensors are computed by

the chassis control module, and a command is transmitted to the ABS actuator and electric unit (control
unit).

• The ABS actuator and electric unit (control unit) control the brake based on the command from the chassis

control module.

• When cornering, driver operation is reduced and vehicle behavior is smoothened.
• When the VDC function is turned OFF with the VDC OFF switch, active trace control function also turns

OFF.

• When the active trace control function operates, operation display can be checked on the information display

in the combination meter. However, when assist control operates to an excessive degree during cornering,
this is not displayed. Refer to 

DAS-187, "INFORMATION DISPLAY (COMBINATION METER) : Chassis

Control Display"

.

• The active trace control function can be turned ON/OFF by operating the steering switch. However, even

when turned OFF, a portion of functions (emergency avoidance, etc.) turn ON. Refer to 

MWI-71, "INFORMA-

TION DISPLAY : System Description"

.

• When a malfunction occurs in active trace control function, the master warning lamp illuminates and at the

same time the information display in the combination meter informs the driver.

NOTE:
• Active trace control function may not be effective in all driving environments (traction conditions, etc.).
• When active trace control function operates, vibration may be transmitted to the brake pedal, an operation

sound may be heard, and a feeling of deceleration may be felt. These are not symptoms of malfunctions and
indicate normal operating conditions.

[CHASSIS CONTROL]

SYSTEM

• Even when active trace control function OFF is selected with chassis control setting, it is not turned com-

pletely OFF for continuing to provide assistance in scenes where steering load is in the high excess range
(emergency avoidance, etc.).

OPERATION CHARACTERISTICS

• This performs assistance when switching from deceleration (brake

operation) to acceleration (accelerator operation) when driving on
a curve. It operates the brake automatically to stabilize cornering,
and smoothens acceleration in the longitudinal and lateral direc-
tions.

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

of the vehicle.

• For the purpose of improving responsiveness during excessive

steering operation, such as emergency avoidance steering, etc.,
the brake is applied to the inside wheel of the steering direction
and causes turning moment to be generated.

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

[CHASSIS CONTROL]

SYSTEM

• When driving on a curve, change of the steering operation angle is

controlled, vehicle movement is smoothened and cornering with a
stable feeling is realized simultaneously, by controlling the brake
on the inner wheel, according to accelerator operation.

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

of the vehicle.
