System Description

• The driving condition 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) control the brake based on the command from the chassis control module (with built in steering angle sensor).
• When the OFF the VDC system, the active ride control is also completely turned OFF.
• When a malfunction occurs in active ride control function, the master warning lamp illuminates and the information display in the combination meter informs the driver.
  NOTE:

  • Active ride control function may not be effective in all driving environments (traction conditions, etc.).
  • When active ride 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 

• When driving on an uneven road surface, mainly the rotation speed information of each wheel is computed by the chassis control module (with built in steering angle sensor) to estimate vertical G, and a command is transmitted to the ABS actuator and electric unit (control unit).
• The ABS actuator and electric unit (control unit) control brake fluid pressure (brake force) according to the command from the chassis control module (with built in steering angle sensor).
• By controlling the brake fluid pressure (brake force), behavior of the vehicle in the vertical direction decreases, and riding comfort is improved.
