Automobile electromagnetic valve control circuit and control method thereof

Abstract

The invention relates to the technical field of electromagnetic valve control, in particular to an automobile electromagnetic valve control circuit and a control method thereof. The automobile electromagnetic valve control circuit comprises a signal input module, a power source module, a control module, a driving module and a power amplification module. The signal input module is used for receiving action signals of electromagnetic valves and sending the action signals to the control module; the control module is used for controlling the power source module according to the time sequence to output different voltages so as to provide power for the electromagnetic valves and controlling the driving module to drive the corresponding electromagnetic valves to work; the power source module is used for converting the voltage of an automobile power source into corresponding voltage and outputting the power according to a control signal of the control module; and the driving module is used forbeing connected with the power amplification module according to the control signal of the control module; and the power amplification module is used for being connected with the electromagnetic valves and the power source module. An automobile electromagnetic valve control device is provided. High-speed response of the electromagnetic valves is achieved, the response time is greatly shortened, meanwhile the buffering technology is utilized, application to the occasion of high-speed adjustment is achieved, impact caused by high-speed action is reduced, and the noise is lowered.

Description

technical field [0001] The invention relates to the technical field of solenoid valve control, in particular to an automobile solenoid valve control circuit and a control method thereof. Background technique [0002] The power supply of the existing solenoid valve driving device adopts a 12V constant voltage power supply (automotive power supply), and drives the solenoid valve by controlling the conduction and disconnection of the power supply. The advantages of this control method are simple circuit, low cost, and disadvantages The reason is that the response speed is very slow, which cannot meet the requirements of high-speed response and fast adjustment. Contents of the invention [0003] The object of the present invention is to aim at the defects of the prior art, and provide an automobile solenoid valve control circuit and its control method with fast response, small working impact and low opening noise. [0004] A kind of automobile electromagnetic valve control ci...
