Distributed Independently Driven Vehicle Control System with Active Attitude Adjustment Capability

Abstract

The invention discloses a control system for distributed-type independent-driving vehicles with the posture adjusting capability. The control system comprises a plurality of sensors, an information sensing system, an actuator, a secondary controller, and a vehicle control system. The sensors are used for detecting current road surface parameters and current vehicle parameters; the information sensing system is used for obtaining road surface information and vehicle information according to the current road surface parameters and the current vehicle parameters; the actuator is used for outputting the road surface information and the vehicle information to the distributed-type independent-driving vehicles with the posture adjusting capability; the secondary controller is used for controllingthe actuator to drive the vehicles according to vehicle wheel torque signals and suspension stroke signals; and the vehicle control system is used for receiving decision instructions input by a driver or an intelligent decision system and obtaining the vehicle wheel torque signals and the suspension stroke signals according to the decision instructions and the obtained road surface information and vehicle information so as to control the secondary controller to control the actuator to drive the vehicles. According to the control system, the vertical posture control capability of the vehiclesis additionally achieved, the posture stability of the vehicles is greatly improved, and the motion stability of the vehicles is effectively improved.

Description

technical field [0001] The invention relates to the technical field of vehicle control systems, in particular to a distributed independent drive vehicle control system with active attitude adjustment capability. Background technique [0002] Traditional vehicles generally adopt a passive suspension system, which does not have the ability to actively adjust the vehicle attitude. The vehicle's active attitude adjustment capability can keep the vehicle on a relatively stable body platform during driving, which plays an important role in both military and civilian vehicles. For military armored vehicles, the active vehicle attitude adjustment function can increase the coverage of the fire strike system, improve the strike accuracy, make the armored vehicle more flexible in combat, and facilitate personnel to get on and off the vehicle. For civilian vehicles, the active posture adjustment function can simultaneously optimize and coordinate the driving comfort and driving stabili...

Problems solved by technology

[0004] Related technologies are still relatively deficient in the development of active vehicle attitude adjustment technology, and the design of the distributed independent drive vehicle control system does not take into account the control of vehicle attitude (vehicle vertical direction)
