1. Device for regulating the stability of vehicles for land vehicles, comprising:

  • an electronic control unit (ECU) for receiving a first, a second and a third output signal (GR, Temp, O-GR), a yaw rate sensor (GRS) for delivering the first output signal (GR), which represents a yaw rate of the vehicle, wherein the second output signal (Temp), which is an output signal of the yaw rate sensor (GRS), represents the operating or ambient temperature of the yaw rate sensor, and a sensor arrangement (SENS) for delivering the third output signal (0-GR), which represents a non-yawing state of the vehicle, wherein the electronic control unit in a learning mode determines a temperature-related zero offset value from the first output signal in accordance with the second output signal and stores it in a data memory (RAM) if the third output signal indicates a non-yawing state of the vehicle, and in an operating mode reads a temperature-related zero offset value out of the data memory in accordance with the second output signal and corrects the first output signal with this zero offset value in order to generate a control signal for controlling the road behavior of the vehicle.
