Abstract

The invention provides an electric bus integrated control hardware in-loop test platform and a test method. The electric bus integrated control hardware in-loop test platform is formed by an air source component, a line control air brake system, a conventional brake component, a driving control component, a signal simulation component, a target machine, and a host computer based on line control air brake, and the electric bus integrated control hardware in-loop test method comprises an acceleration test, a brake test and a steering test. According to the test platform and the test method, accurate adjustment of the brake pressure of four wheels is realized through front and rear axle proportion relay valves and four ABS solenoid valves in a line control air brake system, and integrated control of electric buses is realized with the combination of signal simulation components including a two-degree-of-freedom rotation platform and a wheel speed simulation motor and the corresponding test method.

Description

technical field [0001] The invention belongs to the technical field of hardware testing of electric passenger car control systems, is based on a wire-controlled air pressure braking system, and specifically relates to an electric passenger car integrated control hardware-in-the-loop test platform and a test method. Background technique [0002] In recent years, with the rapid development of our country's economy, the highway passenger traffic has increased year by year, and the proportion of passenger vehicles in the highway passenger transportation system has become larger and larger, and their use has become increasingly frequent. However, due to the large number of passengers carried by the passenger car, the large weight and volume, and the high center of gravity, accidents such as rollover and sideslip often occur, causing a large number of casualties. With the improvement of people's safety awareness and the formulation of relevant national laws and regulations, the saf...
