ABSTRACT:
In an optimized hydraulic brake system, a pedal travel sensor is used to improve pedal feel. In order to improve pedal feel, a low pressure is detected in the brake booster and the brake hydraulic system is used to increase wheel pressure. This prevents the operator from having to exert an increasing large force on the brake pedal during a deceleration situation.
