The apparatus is used for monitoring sensors in a vehicle which generate signals each representing different physical variables. The apparatus contains a first arrangement with which, for at least two sensors and on the basis at least of the signals generated by them, comparison variables defined identically for the sensors are determined. The apparatus also includes a second arrangement with which, as a function of at least the determined comparison variables, a reference variable is determined. On the basis of at least the determined reference variable, a monitoring operation for at least one sensor is performed in a third arrangement. In addition to the third arrangement, the apparatus further includes a fourth arrangement with which, for at least one sensor, a correction of the signal generated by the fourth arrangement is performed, at least as a function of the reference variable.
An apparatus for monitoring sensors in a vehicle, the sensors generating signals representing different physical variables, the apparatus comprising:
A method for monitoring sensors in a vehicle, the sensors generating signals, each of the signals representing a different physical variable, the method comprising the steps of:
An apparatus for monitoring sensors, the sensors being arranged in a vehicle and generating signals, the sensors including a rotation rate sensor generating a first signal, a steering angle sensor generating a second signal, a transverse acceleration sensor generating a third signal, and wheel rotation speed sensors generating fourth signals, each of the wheel rotation speed sensors being associated with a respective one of the wheels of the vehicle, the apparatus comprising:
