    摘要: A method for operating a vehicle braking system for motor vehicles including a hybrid or electric drive and hydraulically actutable wheel brakes on the front axle, wherein the wheels associated with the rear axle are driven at least partially by an electric motor that can be operated as a generator to recover braking energy and, in generator mode, exerts a braking force on the vehicle wheel associated with the respective axle, thereby generating a drag torque including the braking torque and the regeneration torque of the electric drive, the drag torque being separately regulatable on the front and rear axles. To prevent overbraking of the rear axle and a loss of driving stability of the vehicle, a regeneration torque acting on the rear axle is controlled or regulated such that the drag torque acting on the rear axle does not exceed a maximum drag torque value associated with that axle.

    摘要: Disclosed is a method of monitoring tire pressure monitoring systems in a motor vehicle. The motor vehicle has a tire pressure monitoring system with indirect measurement which detects tire inflation pressure loss on the basis of wheel speed data, and a tire pressure monitoring system with direct measurement (TPMS) which detects tire inflation pressure loss from tire inflation pressure values measured directly by pressure modules on the vehicle tire. According to the method a warning relating to tire inflation pressure loss emitted by a pressure module of the tire pressure monitoring system with direct measurement (TPMS) is not transmitted to the driver until this tire inflation pressure loss is confirmed by the tire pressure monitoring system with indirect measurement or by all pressure modules that are still working in fail-free manner. Also disclosed is a computer program product.

    摘要: The present invention relates to an electrically operable brake system and a method for its actuation. The brake system and the method are characterized in that the service brake system can be activated by two brake operating devices which are operable by the driver independently of each other. The main advantage which results is that upon failure of a brake operating device which is e.g. configured as a brake pedal module, braking of the vehicle can be achieved by means of the service brake system by way of the second brake operating device. The additional functions intended for the service brake system, such as ABS, TCS, driving dynamics control, brake assist system, etc., may then be implemented, if so desired. The redundant design of the actuation for the service brake permits achieving a high degree of operational safety because full braking functions can be maintained even in case of emergency braking.
