Abstract

The invention provides an electromagnetic valve assembly control device and method, and relates to the technical field of electromagnetic valve assembly control. An MCU is electrically connected with a first driving module, a safety module and a second driving module, the safety module is electrically connected with the first driving module, the electromagnetic valve assembly is electrically connected with the first driving module and the second driving module, the electromagnetic valve assembly is used for being connected with a brake oil way, and the second driving module is used for being turned on or off according to a first driving signal of the MCU so as to control the opening and closing state of the electromagnetic valve assembly. The safety module is used for controlling the first driving module to be in the turned-off state when the MCU breaks down, the safety module is further used for generating a control signal according to a second driving signal of the MCU when the MCU works normally, and the first driving module is used for being turned on or turned off according to a control signal and a third driving signal of the MCU and and supplies power power to the electromagnetic valve assembly when the module is turned on. The device has the advantages that when the MCU breaks down, it can be guaranteed that the first driving module is turned off, and safety is improved.

Description

technical field [0001] The present application relates to the technical field of solenoid valve control, in particular, to a control device and method for a solenoid valve assembly. Background technique [0002] ABS (Anti-lock Braking System, anti-lock braking system) is an important part of a car or motorcycle, which is related to the safety of the driver and passengers. The control of the solenoid valve in the ABS will be directly related to the braking of the vehicle, that is, when the control of the solenoid valve fails, the vehicle may lose its braking ability, resulting in unpredictable hazards. Therefore, the control strategy and fault diagnosis of the solenoid valve in ABS are particularly important, and the solenoid valve should not be uncontrollable under any abnormal conditions. [0003] However, when the MCU (Microcontroller Unit, micro control unit) fails, the driver may not be able to brake, and there is a driving risk. [0004] To sum up, in the prior art, w...
