Vehicle full fly-by-wire manipulation system

Abstract

The invention provides a vehicle full fly-by-wire manipulation system, and belongs to the technical field of ground vehicle control systems. The vehicle full fly-by-wire manipulation system comprisesa man-machine interactive manipulation interface, a man-machine interactive manipulation interface feedback port, an upper computer, sensors and an actuating mechanism. The man-machine interactive manipulation interface comprises an electronic mode rod, an electronic accelerator and brake pedal assembly, an electronic steering wheel and a graphic display. The vehicle full fly-by-wire manipulationsystem has the advantages that the electronic mode rod is used for selecting driving modes, mechanical signals of the electronic steering wheel and pedals are converted into electric signals by the man-machine interactive manipulation interface, the driving modes are selected, accordingly, the electric signals can be parsed in the upper computer according to set laws to obtain corresponding targetcontrol variables, the control variables can be transmitted to the actuating mechanism and can be converted into mechanical output, and corresponding manipulation experience can be sequentially fed to a driver via the man-machine interactive manipulation interface feedback port and interfaces of the man-machine interactive manipulation interface feedback port; mechanical transmission equipment between a common vehicle manipulation interface and an existing actuating mechanism is replaced by electric signal processing, accordingly, the manipulation flexibility and safety can be improved, the integral vehicle weight can be reduced, and the complexity can be lowered.

Description

technical field [0001] The invention belongs to the technical field of ground vehicle control systems, and in particular relates to a vehicle full-fly-by-wire control system. Background technique [0002] Ground vehicles generally refer to all kinds of manned equipment that do not depend on the track and operate on the ground. According to the limited degree of freedom of movement, they can be divided into non-omnidirectional vehicles and omnidirectional vehicles. Non-omnidirectional vehicles take common cars on daily roads as an example. Only the front wheels have the ability to turn, and the plane of the rear wheels is kept parallel to the side of the vehicle body. Therefore, when turning, the rear axle is always on the extension line of the radius of curvature of the turning trajectory. The body pointing of the omni-directional vehicle is completely independent from the direction of the vehicle's center of mass motion velocity vector, and the body pointing and the motion ...

AI Technical Summary

Problems solved by technology

Due to the unfriendly operation interface of omnidirectional ground vehicles, it is difficult to control, which hinders the application of omnidirectional ground vehicles in daily civilian vehicles. The middle driver has unavoidable shortcomings such as blind spots in the field of vision

The difference in the amount of control and the mechanical structure that controls the steering of the vehicle also make it difficult for the automatic driving system to be universally used between omnidirectional ground vehicles and traditional civilian vehicles such as traditional cars
