Abstract

The invention discloses a control device of ABS locking-proof system, which comprises the following parts: signal gathering unit (100), signal processing unit (200), output control unit (300) and executing unit (400), wherein the signal gathering unit (100) gathers wheel speed signal, which generates signal according to changing line of wheel speed; the signal processing unit (200) receives the signal of signal gathering unit (100), which switches the signal into acceleration signal of wheel; the output control unit (300) receives the acceleration signal, which generates decompressing output and / or pressurized output; the executing unit (400) receives decompressing output and / or pressurized output, which adjusts braking force of wheel.

Description

technical field [0001] The invention relates to a control device, in particular to a control device for an automobile anti-lock braking system. Background technique [0002] The ABS anti-lock braking system of automobiles has become an important technology to improve automobile safety. Figure 1 shows a schematic diagram of an ABS anti-lock braking valve body commonly used now. In the figure, the ABS valve body includes eight solenoid valves, and each solenoid valve has an electromagnetic coil. By energizing and disconnecting these electromagnetic coils, the Realize the opening and closing of the electromagnetic valve, so as to realize the control of the wheel braking force. Among them, every two electromagnetic coils cooperate to control a wheel, which can realize the pressure maintaining process, decompression process and increasing pressure during the braking process of the car. pressure process etc. Since these knowledge are well known to those skilled in the art, they ...
