Vehicle hybrid brake system test development testbed

Abstract

The invention provides a vehicle hybrid brake system test development testbed which comprises an industrial control machine, a dSPACE real-time simulation system, a rapid control prototype and hardware-in-loop test switching module, a front wheel EHB module and a rear wheel EMB module, wherein the dSPACE real-time simulation system mainly comprises a processor board, a first I / O (Input / Output) interface board, a second I / O interface board, an FIU fault simulation board and a BOB signal measurement board; the rapid control prototype and hardware-in-loop test switching module comprises a first changeover switch, a second changeover switch, a signal conditioning board, a MicroAutoBox prototype controller, a Rapidpro prototype driver and a product / development ECU (Electrical Control Unit). The vehicle hybrid brake system test development testbed can be used for performing research and rapid verification on a control strategy of a hybrid brake system integrated with multiple functions, and laying a foundation for automatic development of hybrid brake system controllers, is of a modular design, and is clear in structure and compact in arrangement.

Description

technical field [0001] The invention belongs to the field of brake system development, and in particular relates to a vehicle hybrid brake system test and development test bench. Background technique [0002] Safety, energy saving and environmental protection are the eternal themes of the development of the automobile industry. With the development of highways, the increase of vehicle speed and the gradual increase of traffic density, the problem of vehicle safety has become increasingly prominent. As an important part of ensuring the safety of automobiles, the braking system has always been concerned by people. The traditional hydraulic brake system has been developed so far, and its technology has been very mature, and the room for performance improvement is very limited. At the same time, with the improvement of people's requirements for vehicle safety and comfort, control systems such as ABS, ASR, ESP and ACC are integrated into the braking system, which makes the hydr...

Problems solved by technology

At present, many auto parts manufacturers and research institutions have conducted a series of research on EMB and published relevant patents, but EMB has not been promoted and used in mass-produced vehicles. The fundamental reason is that the reliability of the EMB system has yet to be verified. In addition, the driving power required by the EMB system is relatively large, and the 12V power supply commonly used in automobiles cannot meet its requirements.
