The invention discloses an automobile chassis power coordination system. A coordinator is connected with a first diagnosis device and a second diagnosis device through a first switch and a second switch respectively; the first diagnosis device, a first controller, an electronically controlled pneumatic suspension frame actuating mechanism and a first sensor are connected in sequence to form a loop; the second diagnosis device, a second controller, an electric power-assisted steering actuating mechanism and a second sensor are connected in sequence to form a loop; the first diagnosis device is connected with the second controller through a first regulator; the second diagnosis device is connected with the first controller through a second regulator. According to the invention, the coordinator confirms a first power coordination mode or a second power coordination mode according to driving real-time working conditions of automobile; the performance of a controlling main actuating mechanism is improved; an auxiliary actuating mechanism is matched to work, so as to realize coordination control on the electronically controlled pneumatic suspension frame and the electric power-assisted steering system according to real-time working conditions of the automobile; driving smoothness and manipulation stability of the automobile are improved.
Description
technical field [0001] The invention relates to the field of automobile control, in particular to an automobile chassis power coordination system. Background technique [0002] Electronically controlled air suspension and electric power steering are two important subsystems in the car chassis, and their performance directly affects the ride comfort and handling stability of the car. In the past, when researching electronically controlled air suspension and electric power steering, it is customary to separate their influence on vehicle ride comfort and handling stability, that is, to set separate controllers for electronically controlled air suspension and electric power steering. Assuming that the input in the vertical direction has no effect on the yaw motion and lateral motion of the car, that is, the movement of the suspension does not affect the steering system; similarly, the lateral force generated by the tire is only limited to the range of handling stability consider...
