Abstract: A vehicle includes a fault-tolerant braking system that controls a brake assembly which is configured to adjust a braking force applied to one or more wheels. The fault-tolerant braking system further includes a brake-by-wire (BBW) system and a vehicle control module (VCM). The BBW system is configured to control the brake assembly in response to a braking request. The VCM is configured to detect a fault of at least one of the brake assembly and the BBW system. In response to detecting the fault, the VCM selectively operates the vehicle between a normal operating mode and at least one degraded driving mode that limits operation of at least one of the vehicle engine and the vehicle transmission compared to the normal operating mode.

Abstract: A vehicle includes a brake pedal, a master cylinder, a braking circuit with a wheel cylinder, and a brake pressure generator with strokable piston. A pedal feel simulator is coupled to the master cylinder through a switchable valve, the simulator providing a reaction force. An isolation valve closes to isolate the braking circuit from the master cylinder and the simulator circuit. A controller is programmed to place the simulator in fluid communication with an output of the brake pressure generator, and to stroke the piston at a designated diagnostic time. The resulting pressure increase is observed, and the controller checks whether the pressure-increase to piston-stroke relationship is within a predetermined acceptable range for continued operation of a brake-by-wire mode in which the master cylinder is coupled to the simulator circuit and decoupled from the braking circuit.

Abstract: A method for operating a braking assistance system of a vehicle, wherein the braking assistance system assists a braking of the vehicle by a vehicle braking device in the event of a hazard braking. To differentiate between the hazard braking and a normal braking, at least two variables, representing a braking demand of a driver of the vehicle, are ascertained and a threshold value is established for each variable wherein hazard braking is recognized when at least the two variables exceed their particular threshold value, whereupon an automated braking intervention by the braking assistance system is initiated with the aid of the vehicle braking device. Furthermore, at least one driving-situation variable representing the instantaneous driving situation of the vehicle is ascertained and the at least two threshold values are changed depending on the at least one driving-situation variable.
