Abstract

The invention discloses a multi-mode steering system with a nested type dual-rotor steering motor and a control method. The multi-mode steering system comprises a steering shaft, an electromagnetic clutch, a dual-rotor steering motor and an ECU, wherein the electromagnetic clutch comprises an input end and an output end; the electromagnetic clutch is selectively combined with or separated from the input end and the output end; the steering shaft penetrates through a central through hole of the electromagnetic clutch and is capable of driving the input end to rotate; the dual-rotor steering motor comprises an inner rotor and an outer rotor; the inner rotor is connected with the steering shaft which penetrates through the electromagnetic clutch; one end of the outer rotor is connected with the output end of the electromagnetic clutch; a diverter is driven by the other end of the outer rotor; and the ECU is electrically connected with the dual-rotor steering motor and the electromagnetic clutch. The steering system disclosed by the invention has various steering modes and is capable of promoting the safety performance of an automobile and realizing the flexible steering.

Description

technical field [0001] The invention relates to the technical field of automobiles. More specifically, the present invention relates to a nested dual-rotor steering motor multi-mode steering system and control method. Background technique [0002] The car steering system is a system used by the driver to control the direction of the car to ensure that the car turns according to the driver's will. It directly affects the safety, handling stability and driving comfort of the car. Existing steering systems mainly include the following types: mechanical steering systems, hydraulic power steering systems, electric power steering systems, and steer-by-wire systems. [0003] The mechanical steering system takes up a lot of space, the steering is laborious, and there is a phenomenon of "beater", which has been basically eliminated now; the power assist characteristics of the hydraulic power steering system cannot be changed, and its power has nothing to do with the speed of the ve...
