Antilock Brakes / Traction Control Systems: Description and Operation

GENERAL INFORMATION
Active stability control (ASC) has been equipped as a standard.
^ ASC has been added to the transaxle [twin clutch sportronic shift transmission (TC-SST)*1] control [vehicles for TC-SST] and AWD [super all wheel control (S-AWC)*2] control, and the controls are integrated to improve the vehicle stability.
^ The ASC system integrates the traction control (TCL) function and skid control function.
^ When the TCL function detects the slip of driving wheel (for example, during start-up on slippery road), it automatically applies the braking force to the slipping driving wheel. At the same time, TCL reduces the engine output and prevents the wheel spin when it determines that the engine torque is too high for the road surface friction coefficient.
^ When the skid control function determines that the vehicle behavior is in a critical state, it reduces the engine output and applies brake force to four wheels independently to control the vehicle behavior, avoiding the critical state.
^ Brake performance at ASC system failure is ensured by the fail-safe function, and at the same time, the serviceability during service is improved.

NOTE:
^ *1: For the details on twin clutch sportronic shift transmission (TC-SST), refer to technical information manual.
^ *2: For the details on super all wheel control (S-AWC), refer to technical information manual.
^ The active stability control (ASC) has the traction control function and the skid control function. By the integrated control with the anti-lock brake system, the system stabilizes the vehicle attitude and, at the same time, secures the driving force.
