System Description
- Brake force distribution function helps provide a more stable and secure feeling.
- During cornering, when brake operation is performed brake fluid pressure of each wheel is controlled based on steering operation amount by the driver and vehicle cornering status amount detected by each sensor.
- Fail-safe function is adopted. When a malfunction occurs in brake force distribution function, the control is suspended for VDC function, TCS function, brake assist function, brake force distribution function, intelligent trace control function (control of chassis control module) and active ride control function (control of chassis control module). The vehicle status becomes the same as models without VDC function, TCS function, brake assist function, brake force distribution function, intelligent trace control function (control of chassis control module) and active ride control function (control of chassis control module). However ABS function and EBD function are operated normally. Refer to Fail-safe .
