Abstract

The invention discloses an electric bus composite braking hardware-in-the-loop test platform and method based on an electronic-controlled braking system. The test platform is composed of a gas-generating component, the electronic-controlled braking system, a traditional barking component, a wheel speed simulation component, a single chip microcomputer controller, an upper computer and a target machine. The hardware-in-the-loop test platform takes a third generation electronic-controlled braking system of the WABCO company as a basis and combines related hardware and software, so that precise adjustment of braking pressure of front and rear axles and four wheels is achieved, and the control problem of normal braking and emergency braking of an electric bus is solved through a regenerative braking control strategy and an ABS control strategy; by means of the test platform and method, combined testing of the electronic-controlled braking system and a regenerative braking system of the electric bus is achieved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle braking system testing, and relates to a hardware-in-the-loop testing platform for composite braking of electric passenger cars. The test method, the present invention is not only applicable to the development of regenerative braking and ABS / EBS control strategies of commercial vehicles, but also applicable to the error diagnosis of ECU of real vehicles. Background technique [0002] In recent years, as the world's energy depletion and environmental pollution problems have become increasingly serious, governments of various countries have begun to promote energy-saving and new energy vehicles to achieve sustainable development through energy conservation and emission reduction. Among various types of new energy vehicles, pure electric vehicles have attracted more and more attention due to their many advantages, especially pure electric buses have become an important choice for the develop...
