Control method of electric steering system

Abstract

The invention discloses a control method of an electric steering system. Multiple power assisting parameter configuration modes corresponding to vehicle configurations are prestored in the electric steering system, and the electric steering system selects the corresponding power assisting parameter configuration mode according to actual vehicle configuration information to control the electric steering system to provide steering assisting power. The control method has the advantages as follows: pre-calibrated multiple configuration parameters of the electric steering system are stored in a 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 steeringsystem. With the adoption of the scheme, the repeated development cost can be reduced, parameter configuration software is developed once for different vehicle models and then stored in the electricsteering system, different kinds of operation software are selected according to different vehicles with the steering system installed, and the universal adaptability of the electric steering system is improved.

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] ...
