Abstract

PURPOSE:To improve visibility of a braking condition to following cars so as to prevent a rear-end collision and the like by providing a deceleration detector detecting deceleration of a car as change in level of conductive liquid whereby controlling the degree in flashing of a brake light in proportion to deceleration of the car. CONSTITUTION:Both a deceleration detector (level sensor) 7, to which conductive liquid 12 is enclosed, and a control section 4 which is composed of a frequency converter converting the output from said deceleration detector 7 into frequencies, an amplifier and the like are provided between a brake lamp switch 2 and a brake light 6. In the deceleration detector 7, when the brake is applied, the level of enclosed liquid 12 is constituted to be inclined depending on deceleration at that time whereby terminals, a, b, c... become conductive step by step in accordance with the state of inclination, thereby generating an output signal varying step by step. Owing to this constitution, the degree in flashing of the brake light 6 or the quantity of light can be changed in proportion to the quantity of detected deceleration.

Especially on high-speed corridors, a momentary delay in recognition often resulted in rear-end collisions resulting in serious accidents.

A control unit 4 is provided between the brake lamp switch 2 and the brake light 6, and inside the control unit, as shown in FIG. It consists of a frequency converter 8 that converts the frequency, an amplifier 9, and the like. Further, in order to make the motor blink at a constant period after deceleration and while stopped, the deceleration output may be temporarily stored in the latch circuit 11 and then sent as a signal to the frequency converter 8, as shown in FIG.

る。(e) Effect When the car is braked, the sealed liquid experiences deceleration (negative acceleration) and tilts as shown in Figure 4, and depending on the degree of deceleration, a, b, c, d, etc. The terminals become conductive one after another and output a signal. The signal output is sent to a frequency converter, further amplified, outputted as a lamp, and sent to a brake light as a flashing signal. Furthermore, by using the broken line A in FIG. 2 and making it proportional to the degree of amplification, it is possible to add luminous intensity to the degree of blinking.

Since flashing signals are easy to recognize, they are effective in preventing rear-end collisions.
