Abstract: A current sensor with an electrical conductor which has a first connection and a second connection for contacting a power circuit of a vehicle, and with a first and a second current measurement device for detecting at least one measurement value for the current flowing over the electrical conductor, and with a first evaluation circuit which is connected to the first and/or the second current measurement device and can receive the measurement values of the first and/or the second current measurement device and output a current measurement signal depending on the measurement values, and with a second evaluation circuit.

Abstract: A current sensor, fora vehicle battery in a vehicle, with an electrical conductor which has a first connection and a second connection for contacting a power circuit of a vehicle. The current sensor includes a first current measurement device and a second current measurement device for measuring the current flowing over the electrical conductor. An evaluation circuit receives measurement values of the first current measurement device and/or the second current measurement device to output a current measurement signal proportional to the current. The first current measurement device utilizes a Hall effect sensor disposed within a constriction with a reduced cross section of the electrical conductor.

Abstract: A battery sensor for detecting a current flowing through an electrical conductor, wherein the battery sensor has at least two mutually independent measuring devices for detecting the current flowing through the electrical conductor. The measuring devices are structurally and/or electrically completely isolated from one another.

Abstract: An electric vacuum pump actuating module for boosting the braking force of a motor vehicle, including a main controller and a driver circuit for operating the electric vacuum pump. The driver circuit includes a first and a second switch. The first switch switches a supply voltage above a predefined voltage level of an operating voltage of the vacuum pump. The second switch switches a supply voltage below the voltage level of the vacuum pump. The main controller controls the first switch by first control signals and the second switch by second control signals. The actuating module determines a state of the electric vacuum pump as a first piece of information based on a first response of the electric vacuum pump resulting from the first or second control signals. The actuating module assesses the state of the electric vacuum pump as error-free or erroneous operation of the electric vacuum pump.

Abstract: An assembly for controlling an electric vacuum pump for a vehicle, which is connectable by at least one switch, which can be controlled by an electronic control unit, to a supply voltage, wherein the electronic control unit in a start-up phase connects the vacuum pump to an additional electrical resistor between the supply voltage and the vacuum pump.

Abstract: An arrangement for controlling the activity of an actuator (AK) of a brake of a motor vehicle has a first path for a first signal (TRIG1) relating to the activity of the actuator (AK), a second path for a second signal (TRIG2) relating to the activity of the actuator (AK), and a circuit (MOSFET, TRANS, RES3, BAT2) enabling the actuator (AK) to be activated in such a manner that the actuator (AK) is activated if a determined modification of the first signal (TRIG1) and also a determined modification of the second signal (TRIG2) is present. The determined modification of the first signal (TRIG1) is in the opposite to the determined modification of the second signal (TRIG2).
