Abstract

The present invention provides a continuously adjustable steering assist method, system and computer equipment. The method includes: performing steering assist feel calibration, and calibrated three groups of assist map curves in which the steering feel is partial to sporty, balanced, and partial to comfort. A, B, C; the assist map curve is a two-dimensional look-up table based on the steering wheel torque and vehicle speed, output assist current; select the steering assist percentage coefficient; use linear interpolation to look up the table, and perform continuous difference on the final output assist current value , to calculate the final output assist current I D . By selecting the percentage coefficient of the steering assist, the present invention can realize continuously adjustable steering assist hand feel selection, and can switch steplessly whether the hand style of the steering wheel is light when driving, that is, the comfort mode, or sports, that is, the hand is stable; By setting the prohibition switching conditions and setting the dynamic saturation limit value for the output change rate of the power assist current, the safety and smoothness of the power steering mode switching are ensured.

Description

technical field

[0001] The invention belongs to the field of vehicle steering assist, and in particular relates to a continuously adjustable steering assist method, system and computer equipment. Background technique

[0002] The existing electric power steering system generally has a set of fixed power assist parameters, which makes the steering hand force of the steering system a fixed style. If an independent steering multi-mode or a steering multi-mode linked with the calibration style of the vehicle power system is used, there will be two or three sets of assist parameters to match the driver when choosing a sporty, economical or comfortable style. The steering wheel feels corresponding to the change between light and steady style.

[0003] Although the existing technical solutions give the driver the freedom to choose the steering wheel hand force mode to a certain extent, the degree of freedom is not high, and it cannot satisfy everyone's steering wheel hand force st...
