Title: Dozing at the wheel prevention device
Inventor: FUKUDA JUNICHI
IPC: B60K28/06
Filed: 1994-03-22
Abstract: PURPOSE:To judge dozing at the wheel securely not by correction steering cycle at the time of normal driving when falling asleep at the wheel is detected based on driver's correction steering cycle. CONSTITUTION:Steering angle data and car speed data which are detected by a steering angle sensor 10 and a car speed sensor 12 are supplied to a steering cycle calculating section 14 in an ECU to calculate driver's correction steering cycle at the time of normal driving, and it is stored in a storage section 18. A judging section 16 calculates reference cycle based on the correction steering cycle at the time of normal driving and gain determined in accordance with the correction steering cycle to compare it with the current correction steering cycle. Since gain is set to a smaller value as the correction steering cycle becomes longer, it is possible to judge dozing at the wheel securely even of a driver who provides long correction steering cycle at the time of normal driving.
