Zusammenfassung:	A system and a device shut off the accelerator function and converts the accelerator function immediately into a brake function for safety in the event of a malfunction when the accelerator pedal is accidentally depressed by a panic or the like. A new finding correlation data showing a relationship between a driver's body weight W and a pedal stepping force F is obtained, and based on this, an accelerator-brake switching set value A is determined, and an accelerator mechanism which detects a stepping pressure F(s) by a pressure sensor and when the stepping force F exceeds over a set value A, that is, F(s)≥0.8×W×(X/Y), it is determined that an abnormal operation happens, so then the brake sensor sends an emergency signal to ECU to stop the throttle driving means, and also actuate the brake driving means through ECU.
