Description of drawings
Fig. 1 is the enforcement circuit structure diagram of speed of a motor vehicle bust stoplight stop lamp caution control setup.
The specific embodiment
As shown in Figure 1, the sensor of speed of a motor vehicle bust stoplight stop lamp caution control setup adopts existing car speed sensor, be connected to control setup from the voltage signal of electronic vehicle speed sensor 1 output by incoming line, the speed of a motor vehicle voltage signal V of sensor output is as the input of this controller, pass through R1 earlier, R2, C1, C2, the filter circuit that C3 constitutes carries out filtering, receive op amp or differential circuit 2 again, this voltage signal is carried out differential calculation to be obtained speed that the speed of a motor vehicle changes (promptly the speed of a motor vehicle reduces Δ V in unit time Δ t, obtain Δ V/ Δ t), the integrated circuit component of the utility model op amp adopts LM324 to realize, after input vehicle speed signal V is through op amp LM324, be output as (R3C3 Δ V/ Δ t), when having only the speed of a motor vehicle to reduce this output valve just on the occasion of, this is output as negative value when the speed of a motor vehicle raises.The threshold of this output with a positive voltage value compared, and the threshold voltage value can be set up the caution needs that the speed of a motor vehicle reduces rate of change according to reality., receive comparison amplifier then and amplify through circuit current limliting and filtration that R4, R5, C4, C5 form from the op amp output signal.
The working power of the utility model speed of a motor vehicle bust stoplight stop lamp caution control setup can be drawn from automobile storage battery and connect, and is generally 5-12V.
Speed of a motor vehicle bust stoplight stop lamp caution control setup of the present utility model does not need existing electronic vehicle speed sensor structure of modification, and stoplight stop lamp does not need other design yet, just connects single line more and gets final product.
The meaning of the utility model speed of a motor vehicle bust stoplight stop lamp caution control setup is: in the vehicle ' not during belt brake speed reduce the vehicle that is not easy to be followed later and realize, more difficultly on express highway discover, rear-end collision often takes place thus.The information change that the speed of a motor vehicle reduces is controlled stoplight stop lamp by electronic circuit, and rear brake lamp is glittering when the speed of a motor vehicle hurriedly reduces, and has seemed the front truck belt brake, and the driver who follows vehicle to the back improves traveling security with caution.So we remind the controller of back car chaufeur vigilance according to speed of a motor vehicle changing down control stoplight stop lamp light, the variable signal that the speed of a motor vehicle is reduced is used to control stoplight stop lamp, the caution back is followed vehicle driver's front truck and is a significant slowdown, and the accident of express highway is significantly reduced.
