A control method for an electric steering system

Abstract

The invention discloses a control method of an electric steering system. The electric steering system pre-stores a plurality of power assist parameter configuration modes corresponding to the vehicle configuration, and the electric power steering system selects the corresponding power assist parameter configuration mode according to actual vehicle configuration information. To control the electric steering system to provide steering assistance. The advantage of the present invention is that: the configuration parameters of various electric steering systems calibrated in advance are stored in the controller, and the steering system configuration parameters corresponding to the vehicle configuration parameters are selected according to the actual vehicle parameters to control the electric steering system. The cost of repeated development, the parameter configuration software is developed once for different models, and then stored in the electric steering system, and then different operating software is selected according to the steering system installed in different vehicles, which improves the general adaptability of the electric steering system.

Description

technical field [0001] The invention relates to the technical field of electric steering, in particular to a control method of an electric steering system. Background technique [0002] With the introduction of new power system technologies, the diversification of vehicle power systems and the universality of electric power steering systems (EPS). Vehicles with different powertrains or new technologies do not have different needs for EPS power assistance, but the same car may be suitable for both powertrains and new technologies such as start and stop, and there is also the possibility of new energy powertrain configurations, such as EV , PHEV, the traditional approach is to design and develop an EPS software for different vehicle models. This method is time-consuming and laborious, and increases the cost of vehicle development. If EPS has universal adaptability to these configurations, it will be greatly reduced. EPS development work. Contents of the invention [0003] ...
