Brake Override System: Description
When the vehicle is being driven with the accelerator pedal depressed, depressing the brake pedal without releasing the accelerator pedal will activate the brake override system to restrict driving torque. The conditions for activating the brake override system as well as the items that are controlled are explained below.
Activation Conditions:
- Vehicle is being driven at or above a specified speed.
- The accelerator pedal is depressed beyond a specified level, and then the brake pedal is depressed.
Brake override control may not be performed depending on the relationship between accelerator pedal angle and vehicle speed.
Items Controlled:
- Driving torque is restricted.
HINT:
During brake override system control, the value for the accelerator pedal angle (which is used for hybrid control) is forcibly reduced to a specified value. For this reason, the Data List value for Accelerator Degree (the value used for driving torque control) will be replaced with a specified value regardless of the actual accelerator pedal angle (Accel Pedal Pos #1, Accel Pedal Pos #2).
Deactivation Conditions:
Deactivation occurs when either of the following conditions is met:
- The master cylinder pressure decreases below a specified value.
- The actual accelerator pedal angle increases or decreases beyond the specified range.
