In-the-loop simulation test system for electronic parking brake system

Abstract

The invention discloses an in-the-loop simulation test system for an electronic parking brake system, which comprises a computer, a data acquisition card, a high-speed CAN card, a hardware interface circuit, a pressure sensor, an electronic parking brake system controller and an electronic parking brake actuating mechanism. Various kinds of information are input by the computer, test software simulates actual automotive parameters according to the input parameters, the information is sent to the electronic parking system controller through the high-speed CAN card and the data acquisition card, the electronic parking brake system controller controls the actions of the actuating mechanism, an indicator lamp and an alarm and feeds the actions back to the computer through an actuating mechanism test system and the data acquisition card, and thus, a closed-loop test system is formed. The in-the-loop simulation test system for the electronic parking brake system has the advantages that: the analog simulation efficiency is high; the adjustment period of the EPB operation environment is short, simple and low in cost; the program parameters can be changed at any time according to the different vehicle models; and the application range is wide; and the development cycle is short and the unnecessary resource waste is reduced.

Description

technical field [0001] The invention belongs to the technical field of debugging equipment for electronic parking brake systems of motor vehicles, and in particular relates to an in-loop simulation test system for electronic parking brake systems. Background technique [0002] At present, most motor vehicles use traditional mechanical parking brake systems. In order to improve the safety and comfort of motor vehicles, drivers can have the opportunity to enjoy the improvement of safety, convenience and comfort performance brought by modern technology. Now automakers in some developed countries are beginning to develop electronic parking brake systems (EPB: Electrical ParkBrake) for motor vehicles. Electronic parking brake systems are part of parking brake technology, and electronically controlled parking replaces traditional The handbrake brake improves the safety and comfort of the vehicle. [0003] The electronic parking brake system is mainly composed of left and right re...
