Abstract

The invention relates to a switching control method of an electric auxiliary steering module and an electric hydraulic steering module. A control unit drives the electric auxiliary steering module tooperate; when the speed information is not greater than the vehicle speed threshold value, the electric hydraulic steering module is driven to operate, so that the electric auxiliary steering module and the electric hydraulic steering module jointly provide the auxiliary steering force for one same direction host machine; when the torque information is not smaller than the torque threshold value,the control unit drives a hydraulic motor of the electric hydraulic steering module to operate at a rotating speed greater than the preset rotating speed; when the torque information is smaller than the torque threshold value, the control unit drives the hydraulic motor of the electric hydraulic steering module to operate at a rotating speed smaller than the preset rotating speed. Therefore the steering power provided by the electric auxiliary steering module and the electric hydraulic steering module for the direction host machine can be regulated, so that the whole electric power loss is reduced.

Description

technical field [0001] The invention relates to a vehicle control method, in particular to a switching control method of an electric auxiliary steering module and an electric hydraulic steering module. Background technique [0002] Existing large vehicles include a steering wheel, a linkage module connected to the steering wheel, an electro-hydraulic steering module (EHPS) linked by the linkage module, and an electro-hydraulic steering module linked by the electro-hydraulic steering module. When the electro-hydraulic steering module operates, the linked steering master can apply an auxiliary steering force to the steering master according to the torque of the steering wheel, so as to turn the large vehicle. [0003] However, once the electro-hydraulic steering module is activated, it will continue to consume electricity, even when the large vehicle runs in a straight line without steering, it will continue to consume electricity, so it is a huge waste of electricity.
