PURPOSE:To inform the driver of the danger of a running state such as running on a cruve, by detecting a parameter corresponding to the lateral acceleration of a vehicle and the speed and issuing an alarm when both of them become (t). CONSTITUTION:A rotation angle detector 1 detects a handle steering angle signal X as a parameter corresponding to the lateral acceleration of the vehicle, and a speed sensor 2 detects a voltage signal Y corresponding to the speed of the vehicle. The steering angle signal X is inputted to n-number of comparators 31-3n different in reference level, and the speed signal Y is inputted to similar comparators 41-4n. If the output of any comparator 3 is turned on because of a high lateral acceleration (a large steering angle due to a sharp curve) and the output of a corresponding comparator 4 is turned on because of a high speed, one of AND circuits 51-5n issues the output, and an alarm 8 is operated through a driving circuit 7. |
