PURPOSE:To shorten an unstable time of sensor output directly after beginning to run to improve reliability of control of a vehicle by detecting the condition of a vehicle directly before beginning to run, and providing a current supply control part to previously begin current supply to a yaw rate sensor. CONSTITUTION:A measuring part 1 is connected to a keyless electric source line to supply current by inserting a key to the key cylinder of a vehicle, and the power of a control unit part 2 is taken from an ignition power source IG line. Because current is supplied to the measuring part 1 by inserting the key to the key cylinder, the measuring part 1 can be started at least a few seconds before beginning to run of the vehicle. Hereby, the unstable time of a sensor directly after beginning to run can be shortened. |
