A warning light drive circuit

Abstract

The invention provides a warning light driving circuit. The warning light driving circuit comprises an ABS input signal end, an ABS (anti-locked braking system) output signal end, an EBD (electric brake force distribution) input signal end, an EBD output signal end, a power source positive electrode and a power source negative electrode, wherein the ABS input signal end is connected with an ABS controller; the ABS output signal end is connected with an automobile meter light; the EBD input signal end is connected with an EBD controller; and the EBD output signal end is connected with the automobile meter light. An amplifier switch circuit, a filtering circuit, an anti-jamming circuit and a voltage stabilizing circuit are added to the warning light driving circuit of a warning light driving module. The anti-jamming performance of the product is improved, the safety and stability of the product are improved, and product quality is guaranteed. The service life of the product is prolonged, and meanwhile the production cost is controlled.

Description

technical field [0001] The invention relates to a warning light driving circuit. Background technique [0002] The ABS anti-lock braking system means that the wheels will not lock when braking. It is conceivable that when the driver quickly depresses the brake pedal during emergency braking, the front wheels will not be locked, and the steering ability still exists, so it is completely possible to take measures to avoid the danger ahead during braking. If the rear wheels will not be locked, side skidding and tail flicking will not occur, and the control of the vehicle body will still exist, which will reduce the possibility of danger. After the previous simple analysis, in fact, the most important function of ABS is not to shorten the braking distance, but to maintain the directional stability of the car as much as possible during braking. When the brake anti-lock braking system works, the friction between the wheel and the road surface is rolling friction, which will make...

AI Technical Summary

Problems solved by technology

Because in the case of power failure, when the driver is in an emergency braking situation, the ABS system needs to be activated in order to prevent the safety of the vehicle due to anti-lock braking. However, the ABS system control unit at this time has no power supply and cannot activate this function. , will cause the danger of the vehicle in emergency braking (locking)
