A battery sensor for sensing at least one battery parameter including at least two measuring units. The measuring units each include at least one sensing device for sensing at least one measured value and at least one evaluation circuit for determining at least one battery parameter from the respectively sensed at least one measured value. An evaluation unit is provided, which compares the battery parameters determined by the evaluation circuits, and outputs an error signal in the event that a defined difference between the battery parameters is exceeded.

The invention relates to a method for controlling a start-up of an electric vacuum pump for a vacuum system of a vehicle, wherein the start-up can occur according to at least two different start-up modes, i.e., according to a standard mode and according to at least one special mode, wherein in the standard mode the vacuum pump is connected to a supply voltage in a non-clocked manner and in the special mode the vacuum pump is connected to a supply voltage in a dynamically clocked manner.

A method for supplying vacuum for a pneumatic brake booster for a motor vehicle braking system, using an electromotively-driven displacement type pump assembly. At least one pressure sensor for monitoring a pneumatic pressure is associated with the pump assembly, and electric signals of the pressure sensor are fed to an electronic unit, analyzed, and processed in order to regulate the pressure. A plausibility check of the pressure sensor signal is carried out by a pressure value amplitude being determined, by signal analysis, in the form of a difference between a maximum pressure value and a minimum pressure value within a stroke of the displacement element, and this being compared to a stored comparison value wherein if the pressure value amplitude deviates from the comparison value by a defined amount, the signal of the pressure sensor is then defined as implausible.

A computer-implemented method for monitoring the function of a safety monitoring system of a control unit of an actuator system of a motor vehicle, wherein it is checked by the function monitoring whether the safety monitoring is performed faultlessly, wherein the safety monitoring is carried out by a first monitoring entity and the function monitoring is carried out by a second monitoring entity, wherein the first monitoring entity sends a result of the safety monitoring as an information item to the second monitoring entity at defined time intervals, wherein the first monitoring entity and the second monitoring entity are free of a common interface, wherein the information item is received by the second monitoring entity by utilizing an interface between the second monitoring entity and the control unit, and wherein the information item is coded in a format which cannot be interpreted by the control unit.

In a method for controlling an electronic parking brake system and an electronic parking brake system, a travel-optimized method is used to achieve the released state of the parking brake system. When the parking brake is applied, travel-force values are detected and a plausibility check is run, the values being used to arrive at a first optimized position when the brake is released. If the residual force applied to the brake exceeds a threshold value, the parking brake is released even more until the value remains just under the threshold value or until a maximum defined release travel is achieved.

Electronic parking brake and method for controlling an electronic parking brake

In a method for controlling at least one electromechanical parking brake unit in a vehicle, the current vehicle speed is detected by a speed sensor system in the form of a speed measuring signal, and a deceleration measuring signal displaying the current vehicle deceleration is detected by at least one acceleration sensor system. In the event of a defective speed signal or a failure of the speed sensor system, the electromechanical parking brake system is operated in an emergency operation mode wherein, at the beginning of a braking, a dynamic braking function is provided by the electromechanical parking brake unit. Advantageously, the current vehicle deceleration is determined from the deceleration measuring signal and compared with a pre-determined minimum deceleration value, and if the determined current vehicle deceleration falls short of the pre-determined value in the emergency operation mode, a static brake function is provided by the electromechanical parking brake unit.

Method for controlling at least one electromechanical parking brake unit of an electromechanical parking brake system

During service and repair work on an electric parking brake () of a motor vehicle, there is the problem that, in order to switch into a service mode in which the parking brake () can be completely opened, in order for example to be able to exchange a brake cable, a special diagnosis unit must generally be used. A diagnosis unit of this type is however not always available in workshops. It is therefore proposed to carry out the switch into the service mode of the electric parking brake () with at least one control element () of the motor vehicle. Here, it is provided that, for safety reasons and in order to avoid an undesired switch into the service mode, the actuation of the at least one control element () must take place according to a predefined input procedure.

In a method for controlling an electromechanical parking brake system (EPB) of a vehicle, wherein the electromechanical parking brake system (EPB) comprises at least one actuating element (BE), at least one brake mechanism unit (BME), and at least one control device (SG), in order to statically brake the vehicle, the actuating element (BE) is actuated and, depending thereon, the at least one brake mechanism unit (BME) is applied with a predetermined application speed (AV) controlled by a control and evaluation routine (SAR) run in the control device (SG). The vehicle speed (V) prevailing when the at least one actuating element (BE) is actuated is advantageously determined and the application speed (AV) of the brake mechanism unit (BME) is selected depending on the determined vehicle speed.

In a system for controlling a parking brake of a brake system of a motor vehicle, a first target value for the braking force of the parking brake is predefined by a operating element for the parking brake and the braking force for the parking brake is released by a operating element. When a start-up intention is detected, the control system minimizes the braking force of the parking brake in relation to the first target value, in accordance with the environmental conditions of the motor vehicle. For the first time a provisional minimization of the braking force of a parking brake for a foreseeable start-up situation is permitted, thus allowing the start-up operation of a motor vehicle to be as comfortable as possible with maximum security of the automatic functions. The system is particularly suitable for electromechanical parking brakes.
