Problems solved by technology

However, due to the limited data accumulation of domestic manufacturers in China, there is still a certain gap between the basic hardware level and industrialization level of the controller compared with foreign countries, and it cannot really guarantee the stability of unmanned vehicles.
Moreover, during the driving process, the energy feedback rate is also low due to the instability of the control

Abstract

The invention relates to a drive-by-wire chassis control system based on an ECU. The drive-by-wire chassis control system based on the ECU mainly comprises an industrial personal computer, the ECU, a drive-by-wire chassis and an energy feedback device. Wherein the industrial personal computer is adopted to obtain vehicle operation data, and generating a control signal according to the vehicle operation data; generating a control instruction according to the control instruction by adopting the ECU; the drive-by-wire chassis is used for braking according to the control instruction to generate braking force; the energy feedback device is used for generating reverse power generation torque according to the braking force to generate electric energy, so that high energy feedback efficiency is guaranteed while the running stability of the unmanned vehicle is improved.

Description

technical field [0001] The invention relates to the field of unmanned vehicle control, in particular to an ECU-based control system for a chassis by wire. Background technique [0002] As the brain of the execution layer of the intelligent driving vehicle, the Electronic Control Unit (ECU) of the intelligent driving vehicle receives and processes the operating instructions issued by the intelligent driving domain controller or peripheral accelerator, gear, and brake, and decomposes and controls them. The running, steering, braking and comfort electronic equipment operation of the vehicle in the automatic driving mode (unmanned driving mode, remote driving mode remote driving mode) and assisted manual driving mode. The research and industrialization of key technologies of ECU for intelligent driving vehicles will help to promote the industrialization process of intelligent driving vehicles. [0003] Vehicle manufacturers such as Toyota, Nissan, General Motors, and Ford, and ...
