Abstract

The application provides a solenoid valve assembly control device and method, which relate to the technical field of solenoid valve assembly control. The MCU is electrically connected to the first driving module, the safety module and the second driving module respectively, the safety module is electrically connected to the first driving module, and the solenoid valve assembly is electrically connected to the first driving module and the second driving module respectively, wherein the solenoid valve assembly It is used to connect with the brake oil circuit. The second drive module is used to turn on or off according to the first drive signal of the MCU to control the opening and closing state of the solenoid valve assembly. The safety module is used to control the first drive when the MCU fails. The driving module is in the off state, and the safety module is also used to generate a control signal according to the second driving signal of the MCU when the MCU is working normally, and the first driving module is used to turn on or off the third driving signal of the MCU according to the control signal , and powers the solenoid valve assembly when turned on. The present application has the advantage of being able to ensure that the first driving module is turned off when the MCU fails, thereby improving safety.

Description

A solenoid valve assembly control device and method technical field The application relates to the technical field of solenoid valve control, in particular, to a solenoid valve assembly control device and method Law. Background technique ABS (Anti-lock Braking System, anti-lock braking system) is an important zero in automobiles or motorcycles. components, which are related to the life and safety of drivers and passengers. The control of the solenoid valve in ABS will be directly related to the braking of the vehicle When the control of the solenoid valve fails, the vehicle may lose its braking ability, resulting in unpredictable hazards. Therefore ABS The control strategy and fault diagnosis of the solenoid valve are particularly important, and the solenoid valve should not appear under any abnormal working conditions. uncontrollable situation. [0003] However, when the MCU (Microcontroller Unit, micro control unit) is down, there may be a driver If you canno...
