Abstract: A backup system for an electronic parking brake, EPB, of a commercial vehicle ensures a safe state even during electric power failure of a power supply unit of the EPB. The backup system includes a detection unit for detecting the power failure, a storage device for storing sufficient electric power to perform a switch into the safe state, a boost circuit configured to charge the storage device during standstill of the vehicle and to discharge the storage device during motion of the vehicle, and a switch device configured to supply the electric power of the storage device to the EPB if the power failure is detected by the detection unit.

Abstract: A system and method for controlling a vehicle wheel brake are provided. The system includes one or more inertial sensors disposed within a handle coupled to, and configured for movement relative to, a fixed reference frame in the vehicle between a neutral position and one or more input positions. Each sensor generates an inertial measurement signal indicative of a value of an inertial measurement associated with movement of the handle and sensor between the neutral and input positions. A controller receives the signals, identifies a turning point in a rate of change of the value of one of the inertial measurement indicated by the signals, and generates an operator command signal when the value meets a predetermined condition. The operator command signal is configured to cause one of application or release of the wheel brake.

Abstract: An operator interface for a wheel brake control system in a vehicle includes a handle configured for coupling to a fixed reference frame in the vehicle. The handle is configured for movement relative to the fixed reference frame about a pivot axis between a neutral position and one or more input positions. One or more inertial sensors are disposed within the handle. Each sensor is configured to generate an inertial measurement signal indicative of a value of a corresponding inertial measurement associated with movement of the handle and the sensor between the neutral position and the input positions. A controller disposed within the handle is configured to generate an operator command signal responsive to the inertial measurement signals. The operator command signal is configured to cause application or release of a brake in the vehicle.
