Embodiment Construction

[0030] Referring to Fig. 1, the present invention has multiple implementation modes, and the hydraulic circuit in the four wheels of the automobile is disc brakes and the hydraulic control device adopts a diagonal double circuit layout as an example to illustrate the hardware of the electronic stability control system of the car Specific implementation of the in-loop test bench. The hardware-in-the-loop test bench of the car electronic stability control system is composed of two parts: the electronic control device and the hydraulic control device. The entire test bench is built into a bench structure, that is, a bracket is first welded with section steel, and then the ready bracket is placed on the ground of the laboratory, and then a working platform is placed on the bracket, that is, a work platform can be installed on it. Mounting table for parts required. The host machine 24 is connected with the target machine 23 with the RS232 serial port bus, the target machine 23 is ...

Abstract

The invention discloses loop testing stand on which the closed car electronic stability control system hardware. The testing stand includes electronic control device and hydraulic control device. The former is made up of host machine, target machine, data collecting card, self-control circuit board, electronic throttle, four brake cylinder pressure transducers, steering handle corner transducer, master cylinder pressure transducer, and brake paddle switch. The latter is made up four brake tongs and friction plates, four brake cylinders, brake master cylinder, and hydraulic pressure regulator. The testing stand can test and study the ESP principle and characteristic, supply testing condition for various control logic searching, reduce real car road test times and cost.

Description

technical field [0001] The invention relates to a hardware-in-loop experimental device of an automobile active safety driving control system, in particular to a hardware-in-loop test bench of a car electronic stability control system. Background technique [0002] The electronic stability control system is an important breakthrough in automotive active safety technology. It integrates the basic functions of the anti-lock braking system (ABS) and the anti-skid control system (ASR), and can identify abnormalities of the vehicle in a short time. Stabilize the trend, and use the intelligent electronic control scheme to make the car's transmission system or braking system produce an accurate response, timely and properly eliminate these unstable driving trends, and keep the car on the desired driving route. There are not many companies in the world that can independently develop and produce electronic stability control systems (ESP), and these companies only provide the assembly ...
