Problems solved by technology

At present, due to the relative immaturity of brake-by-wire and steer-by-wire products, there is no corresponding testing equipment on the market. Therefore, most of the current testing is based on simulation and real vehicle or single-function product testing, which cannot quickly and effectively complete the whole set. Test detection of chassis system by wire

Abstract

The invention discloses a drive-by-wire chassis test bench. The bench comprises a bracket, a steering wheel, a steering system, a braking system, a center console, an operation input device and a display, wherein the bracket is the integral frame structural member of the drive-by-wire chassis test bench, the steering wheel, the steering system, a brake output device and the braking system are fixed on the bracket, the steering wheel is connected with the input end of the steering system, the steering system is connected with the center console, the braking system is connected with the center console, and the operation input device and the display are in electric signal connection with the center console. The system can achieve the unified, comprehensive and efficient detection of the control algorithm and function detection of the intelligent drive-by-wire chassis.

Description

technical field [0001] The invention relates to a test stand for a control-by-wire chassis, in particular to a test stand for a control-by-wire chassis equipped with control algorithm verification and function tests for steering-by-wire and brake-by-wire. Background technique [0002] The intelligent control-by-wire chassis technology is an important assembly part in the future driverless technology, and the core technology of the control-by-wire chassis focuses on intelligent steering-by-wire technology and brake-by-wire technology. At present, due to the relative immaturity of brake-by-wire and steer-by-wire products, there is no corresponding testing equipment on the market. Therefore, most of the current testing is based on simulation and real vehicle or single-function product testing, which cannot quickly and effectively complete the whole set. Test and inspection of the ride-by-wire chassis system. Contents of the invention [0003] In order to solve the above prob...
