Steering assist level control system and method

Abstract

The invention provides a steering power-assisted grade control system and method. The system can comprise an input module, an instrument display system and an electronic power-assisted steering system which are sequentially connected in a signal mode. The instrument display system comprises a human-computer interface, the electronic power-assisted steering system comprises a power-assisted motor, and the tooth ratio of an output shaft of the power-assisted motor is adjustable. The input module generates power-assisted grade arrangement signals according to operating information and sends the power-assisted grade arrangement signals to the instrument display system, the instrument display system displays power-assisted grade arrangement change on the human-computer interface according to the power-assisted grade arrangement signals and sends the corresponding power-assisted grade signals to the electronic power-assisted steering system, and according to the power-assisted grade signals, the electronic power-assisted steering system controls the power-assisted motor to switch the tooth ratio of the output shaft to corresponding matching states and return executing completing signals. According to the steering power-assisted grade control system and method, a power-assisted grade close loop control circuit is formed between the instrument display system and the electronic power-assisted steering system, reliable adjustment of power-assisted grades can be achieved, and safety of driving is improved.

Description

technical field [0001] The invention relates to the technical field of electronic appliances, in particular to a steering assist level control system and method. Background technique [0002] During the driving process, due to the difference in personal physique and physical conditions, the steering force of the steering wheel is often too heavy or too light, resulting in not all drivers being able to adapt to a fixed single steering force, resulting in arm fatigue, and then unconsciously. Accidentally deviate from the steering direction, causing potential safety hazards. However, the existing electronic power steering methods mainly use the mechanical hydraulic fixed force steering method or the ordinary fixed force electronic power steering method, which can only provide a single steering force during driving, and cannot take care of the driving force of all people, making the driver It is easy to cause troubles to steering force and steering wheel control, which affects ...
