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.

Current sensor

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.

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.

Battery sensor

A method for operating a battery sensor and a battery sensor, including a first and second battery sensor connections, load current connection, current measurement device for recording load current, and first and second measuring resistor elements. The first and second measuring resistor element series connected between the load current connection and the second battery sensor connection, a reference current circuit with at least one reference resistor. The reference resistor in contact with the first battery sensor connection and a contact point between the measuring resistor elements. The electrical resistance of the first resistor element determined by switching on the reference current and recording the voltage drops across the first and second measuring resistor element and the battery voltage, determining the reference current from the battery voltage quotient and electrical resistance of the reference resistor element, and determining the electrical resistance of the first resistor element from the recorded voltage drops.

A current sensor device for measuring a current, in particular for measuring a battery current in motor vehicles. The device includes a clamping device for fixing the current sensor device to a maintaining body, an electric resistance element on which the current can be measured by means of a voltage, and an electric mass element by means of which the current sensor device can be electrically coupled to a zero potential. The clamping device, the resistance element and the mass element are integrally formed.

The invention relates to a method for detecting a rollover situation in such a way that a restraint, such as belt tighteners or head airbags, can be released at the right time during rollover. The signals that pertain to several sensors and detect transitional and rotational movements are detected, connected to one another and evaluated.

A vehicle occupant restraining system includes a plurality of safety restraint devices and utilizes a main controller and a safing controller to determine whether or not conditions are proper for deploying each safety restraint device. The system discriminates between front, side, rear, and roll-over impact events and determines which safety restraint devices should be deployed in response to an impact event. The system also independently determines whether to activate a fuel cut-off switch in response to an impact event. The main and safing controllers utilize vehicle data from a main center tunnel sensor assembly and various satellite sensors to make deployment decisions. The safing controller is used to independently verify whether or not the safety restraint should be deployed.

In a method for controlling an occupant protection device in a vehicle and a control device therefor, a crash sensor supplies a crash signal. A crash variable derived from the crash signal is compared with a threshold, the occupant protection device is controlled as a function of the overshooting of the threshold by the crash variable. The threshold includes at least one term which, depending on the configuration of the crash signal, supplies a contribution which raises the threshold or a contribution which lowers the threshold.

In a control configuration for an occupant protection system for side collision protection in a vehicle, an enable signal of a protection configuration generated as a function of transverse acceleration, is delivered to a timer. The timer furnishes an enable signal of a fixed minimum duration for triggering the occupant protection system.

A pressure transducer, in particular for sensing a lateral collision in a motor vehicle, delivers an electric useful signal which is determined by a relative pressure change relating to a pressure event. Low-frequency changes in an output signal of a sensor device, which depend on the ambient pressure, are compensated by a control device with an integrating behavior. The sensitivity of the sensor device, as a manipulated variable, changes in a manner inversely proportional to the ambient pressure. Higher-frequency pressure changes in the output signal of the sensor device are not compensated, but as a result of the variable sensitivity of the sensor device, determine as relative pressure changes the useful signal, which is additionally independent of temperature influences and offset errors of the pressure transducer.
