Mechanism Implementation for a 4WID/4WIS Unmanned Vehicle
This paper proposed a novel mechanism for an unmanned electric vehicle with four-wheel independent driving (4WID), independent steering (4WIS), independent suspending and independent braking. This unmanned electric vehicle adopted the technologies of driving by wire, steering by wire and braking by wire. Which improved the maneuverability of the vehicle greatly and made it achieving straight, oblique, lateral movement, zero radius turning and other movement patterns. Detailed implementation mechanism and virtual prototype of the vehicle were given in this paper. The hydraulic circuit schematic diagram and control method of the braking system were given also.
