System Description

• The steering operation condition by the driver and the information from multiple sensors are computed by the chassis control module (with built in steering angle sensor), and a command is transmitted to the ABS actuator and electric unit (control unit).
• The ABS actuator and electric unit (control unit) controls the brake based on the command from the chassis control module (with built in steering angle sensor).
• When cornering, driver operation is reduced and vehicle behavior is smoothened.
• When the OFF the VDC function, the intelligent trace control function is also completely turned OFF.
• When a malfunction occurs in intelligent trace control function, the master warning lamp illuminates and the information display in the combination meter informs the driver.

NOTE:

• Intelligent trace control function may not be effective in all driving environments (traction conditions, etc.).
• When intelligent 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.

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 directions.

  • 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 momentum to be generated.

• 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.

• When performing quick lane changes and other excessive steering operations, the brake is operated automatically, and erratic vehicle behavior due to steering operation is reduced.
