<p>In a first region of the driver's braking command, regenerative braking produces almost all of the braking torque, whereas the friction brake produces essentially no braking torque. In this region of the braking command, the pressure medium flowing into the wheel brake cylinder as a result of the driver's actuation of the brake pedal, is conducted by appropriate control back to a storage chamber. The first region is limited by a threshold brake pedal travel which corresponds to the maximum braking torque available from the motor. When pedal travel exceeds this threshold, the friction brake and the motor both effect braking.</p> |
