摘要： An electromechanical brake system, particularly for motor vehicles, with a pedal simulator and brake modules is disclosed. A central module is also provided. The connection between the aforesaid modules can be provided by a data bus. The central module evaluates the braking request signals from a sensor device and checks them for errors. Also, a central module supplies and appropriate desired braking value based on the braking request and possibly higher functions such as ABS or ASR. The desired braking value is then conveyed on to the brake module, which then determines the corresponding control signals for the actuators, which interact with the wheels in order to brake the vehicle as the driver requires.

摘要： This invention relates to an electromechanical brake system, in particular for automotive vehicles, which includes a pedal module and at least two brake modules. Further, a central module may be provided. Connection between the aforementioned modules can be made by a data bus. The data bus is provided redundantly. In one embodiment, the central module can evaluate signals of a sensor system and examine them for their errors. Further, the central module can emit a corresponding nominal braking value which then is emitted to the brake modules. Thereupon, the brake modules determine appropriate actuating signals for the actuators which interact with the wheels in order to realize the driver's braking intention.

摘要： A method and system for controlling a brake for motor vehicles. The present invention relates to a method as well as a system for controlling a brake for motor vehicles, which can be electromechanically actuated by means of an actuator, consisting of an electric motor as well as a drive mechanism positioned downstream of the electric motor.

摘要： A device and method to predict and regulate nitrogen concentration in a flow shifting system. In one aspect of the system, a bleed valve fluidly coupled to multiple fuel cell stacks is used to reduce the presence of nitrogen in an anode flowpath. One or more sensors can be used to measure voltage within one or both of the fuel cell stacks. By assessing fuel cell voltage changes within the anode flowpath and equating such changes with nitrogen fraction buildup, the system can manipulate the bleed valve at appropriate times to improve system operability. In one form of equating the sensed voltage changes with the nitrogen fraction buildup, a predictive algorithm can be used by a logic device in a controller to compare the sensed voltage so that the controller instructs the bleed valve when to open and close. In a variation, the controller can compare the sensed voltages against stored data rather than rely on a formula or related algorithm.

摘要： A regenerative braking system and method for a batteriless fuel cell vehicle includes a fuel cell stack, a plurality of ancillary loads, and a regenerative braking device that is coupled to at least one wheel of the vehicle. The regenerative braking device powers ancillary loads when the vehicle is coasting or braking. The fuel cell powers the loads when the vehicle is accelerating or at constant velocity. The regenerative braking device dissipates power in an air supply compressor when the vehicle is traveling downhill to provide brake assistance. The compressor can be run at high airflow and high pressure to create an artificially high load. A bypass valve is modulated to adjust the artificially high load of the compressor. A back pressure valve protects the fuel cell stack from the high airflow and pressure. A controller controls a brake torque of the regenerative braking device as a function of vehicle speed and modulates the bypass valve.
