Hardware-in-the-loop test bench and test method for electronic brake system of commercial vehicle based on TTC580 controller

Abstract

The invention provides a hardware-in-the-loop test bench and test method for the electronic brake system of a commercial vehicle based on a TTC580 controller. The test bench is composed of an air source component, an air pressure test bench component, a controller and a host. The test bench acquires pressure signals of four brake chambers and a throttle pedal opening signal through an analog acquisition channel of the TTC580 controller, outputs a drive signal to a front axle single channel module, two ABS solenoid valves of the front axle and a rear axle double channel module through a PWM output channel of the TTC580 controller, and acquires a brake pedal opening signal and a steering wheel angle signal through a digital acquisition channel of the TTC580 controller. The host and the TTC580 controller are connected by the Ethernet to realize data transmission. The test bench and the test method meet the requirement for rapid development of electronic brake systems for commercial vehicles, and reduce the cost of hardware-in-the-loop test.

Description

technical field [0001] The invention belongs to the technical field of hardware-in-the-loop testing of automotive electronic braking systems. Specifically, the invention relates to a commercial vehicle electronic braking system hardware-in-the-loop test bench and testing method based on a TTC580 controller. Background technique [0002] With the development of the economy and the needs of transportation, the market share of commercial vehicles has gradually increased. However, due to the large amount of people and goods carried by commercial vehicles, the driving safety of commercial vehicles is particularly important. In order to improve the safety of commercial vehicles, foreign vehicle manufacturers such as WABCO, BOSCH, and Knorr proposed the concept of Electronically Braking System (Electronicly Braking System) for commercial vehicles. It has developed into the current complex control system including ABS control, ASR control, ESP control and other control functions, wh...

Problems solved by technology

However, at present, there are few domestic hardware-in-the-loop test benches for the R&D and verification of commercial vehicle electronic braking systems, which cannot meet the needs of rapid development and hardware-in-the-loop testing of commercial vehicle electronic braking systems; and mainstream hardware-in-the-loop testing The test bench usually adopts the controller platform produced by foreign Dspace company, NI company and other companies, the cost of hardware and software is relatively high, which increases the cost of scientific research
