BRAKE CONTROL SYSTEM


  1. SYSTEM CONTROL


    1. When the vehicle starts off on a steep or slippery hill, it may start to descend backward while the driver switches from the brake pedal to the accelerator pedal, thus making it difficult for the vehicle to start off. To help prevent this from occurring, the hill-start assist control temporarily (approximately 2 seconds at the maximum) applies the brakes to all 4 wheels in order to help prevent the vehicle from descending backward.

    2. Without the hill-start assist control, the driver must quickly and precisely switch from the brake pedal to the accelerator pedal. With the hill-start assist control, however, the driver can start off easily and operate the pedal in a relaxed manner, because the hill-start assist control helps prevent the vehicle from descending backward.

    3. Hill-start Assist Control Activation Conditions


      • The skid control ECU judges if the vehicle is on an uphill incline based on signals from the deceleration sensor, and activates Hill-start Assist Control when the vehicle is started with all of the following conditions met.

      Control Activation Conditions

      • The shift lever is in any position other than P or N (Forward climbing and backward climbing).*1

      • The shift lever is in any position other than R or N when starting off forward on an upward incline or in R when starting off backward on an upward incline.*2

      • The vehicle is at a standstill.

      • The accelerator pedal is not depressed.

      • The parking brake is released.

    4. Hill-start Assist Control Cancelation Conditions


      • If any of the following conditions is met, Hill-start Assist Control operation is canceled.

      Control Cancelation Conditions

      • The shift lever is moved to P or N.*1

      • The shift lever is shifted to R or N when starting off forward on an upward incline or from R when starting off backward on an upward incline.*2

      • The accelerator pedal is depressed.

      • The parking brake is operated.

      • Approximately 2 seconds elapse since the operation started.
