The invention discloses a distributed driving high-performance six-wheel steering commercial vehicle intelligent chassis system and a control method, and the system comprises a vehicle frame, a suspension system, a driving and braking system, a steering system and an information perception and control system. The steering angle and the driving force of each wheel are controlled respectively, so that the three-axle commercial vehicle has redundancy and coupling of overdrive and brake system input vectors. Advanced sensing and state sensing equipment is integrated into a multi-wheel steering and multi-wheel driving chassis control framework, a perfect high-performance intelligent chassis system is formed, and the capacity of a multi-shaft heavy-load commercial vehicle for coping with limiting working conditions in the running process is improved. A bottom layer control quantity optimization scheme proposed on the basis of the distributed six-wheel steering chassis has an ideal tire force distribution mechanism, and the stability of a vehicle body is improved. And meanwhile, the multi-motor distributed driving structure has a better energy distribution mode, the efficiency of the driving motors is improved, and the energy consumption is reduced.
