Abstract
The disclosure relates to a sensor assembly for a vehicle, comprising a sensor element for detecting a measurement variable and at least two control devices, each having a measuring circuit and a power source. A first connection of the sensor element is connected to the power source of a first control device. A second connection of the sensor element is connected to a ground connection via a measuring circuit of a second control device. The measuring circuit of the first control device evaluates sensor current detected in a high side path of the sensor element. The measuring circuit of the second control device evaluates sensor current detected in a low side path of the sensor element. A first emergency protective circuit provides an alternative low side path for the sensor element and receives the sensor current if the voltage drop reaches a predefined breakover voltage value.
