Control method and system for automatic parking release of electronic parking brake system

Abstract

The invention discloses a control method and system for self releasing and parking of an electronic park brake system. The control method comprises the steps that whether an engine of an automobile isstarted or not is judged; if the engine is started, whether the automobile is in a parking state or not is judged; if the automobile is in the parking state, whether a braking pedal of the automobileis pedaled downwards or not is judged; if the braking pedal of the automobile is pedaled downwards, whether a current slope value where the automobile is located is less than or equal to a preset slope value or not is judged; if the current slope value where the automobile is located is less than or equal to the preset slope value, whether a gear position of the automobile is switched to a forward gear or a reverse gear or not is judged; and if the gear position of the automobile is switched to the forward gear or the reverse gear, releasing and parking are executed. According to the controlmethod and system, when the automobile is started, the driving intention of a driver is judged by monitoring the change of a gear signal, and whether the current state allows automatic releasing of gear shifting of an electronic park brake (EPB) or not is judged by monitoring the slope value of a pavement, so that safety risk and fuel economy and comfort deterioration brought by EPB parking releasing due to the fact that the driver pedals an accelerator deliberately are avoided, and the more safe, economical and stable effects during starting of the automobile are achieved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a control method and system for automatically releasing and parking an electronic parking brake system. Background technique [0002] With the rapid development of the economy and the automobile industry, people's living standards have been rapidly improved, and automobiles have gradually become the means of travel for ordinary families. [0003] The use of electronic mechanical control in modern automobiles has become more and more extensive. With the innovation of automobile technology, more and more new automobile products have been upgraded from the original mechanical hand brake to the electronic parking brake system (Electrical Park Brake) , referred to as EPB). [0004] At present, the matching EPB on the market is generally equipped with a start release function. When the vehicle starts, it is necessary to step on the accelerator to make the EPB perform parking relea...
