SUDDEN SLOWDOWN ALARM SYSTEM OF AUTOMOBILE

摘要

PURPOSE:To give no alarm when it is unnecessary to inform a sudden slowdown in particular but to emit an alarm alone when it is necessary. CONSTITUTION:Deceleration is calculated from a variation in detecting speed by a car speed sensor 1 by an electronic control unit 2, and when the deceleration is larger than the specified value and that decelerating width is larger than the constant value in a state that the detecting speed is larger than the specified one, a hazard lamp 4 as an alarm is flickered by a hazard lamp driver 3.
