Active Trace Control Function

SYSTEM

ACTIVE STABILITY ASSIST : Active Trace Control Function

- Active trace control function is calculated by ADAS control unit and transmits command to ABS actuator and electric unit (control unit).
- This system senses driving based on the driver's steering and acceleration/braking patterns, and individually controls the braking and application of engine torque to each of the four wheels to help smooth vehicle response.
- When the drive mode selector switch is set to the "SPORT" mode, the amount of brake control provided by
Active trace control function is reduced.
- When the VDC OFF switch is turn OFF the VDC function, the Active trace control function is also turned
OFF.
- Active trace control function is malfunctioning properly, the IBA OFF indicator lamp turns ON.
NOTE:
Effect to decrease delay of vehicle yaw rate in response to steering operation may not always be obtained in all driving conditions (example: when road surface resistance is low).

OPERATION CHARACTERISTICS






Active Trace Control helps enhance the transition from braking into and then accelerating out of corners. Active Trace Control utilizes the vehicle's VDC system to help improve cornering feel by automatically applying brakes, or smoothening engine torque characteristics while accelerating. 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 moment and help turn the vehicle.
- Brake control amount and engine output are controlled according to steering operation status by the driver and vehicle cornering status.





- By preventing a sudden torque change, vehicle behavior moderates. As a result, accelerator pedal operation by the driver is improved.
