Operation Description

Operation 

• The system detects the distance to the vehicle in front with the ICC sensor integrated unit of ICC (Full Speed Range) and judges the necessity of emergency braking.
• The system detects the accelerator pedal release operation of the driver by the accelerator pedal position sensor and estimates the driver's brake operation intention.
• If the system is judged that the emergency braking is necessary or that the driver has the intention to operate the brake it supplies the power supply to the brake booster to apply pre-pressure and adjusts the brake play.
  NOTE: This system will not operate when the vehicle is moving at approximately 32 km/h (20 MPH) or less.

End of Operation 

The pre-pressure function ceases when the following conditions are met:

1. When the driver depresses the accelerator pedal or the brake pedal.
2. If the driver does not operate the accelerator pedal or brake pedal within approximately 1 second.
