Abstract

The invention provides a method for evaluating the steering control efficiency of a vehicle driver. The method comprises the following steps of: installing a steering sensor on a steering column of a vehicle to measure a steering force from the driver, attaching a muscle electrode to the shoulder muscle of the driver to collect a myoelectric signal of the shoulder muscle group of the driver, and establishing estimation equations of effective steering force and total steering force during steering control of the driver by regression analysis in combination with a model of relationship between the driver myoelectric signal and the muscular contraction force. The method achieves the purpose of evaluating the steering control efficiency of the driver and provides a theoretical basis for evaluating the steering comfort of the driver and the performance of the steering system. The method is suitable for the steering control of various vehicles and can be widely applied to the evaluation of driving comfort and steering system performance.

Description

technical field

[0001] The invention relates to a method for evaluating a driver-vehicle system, in particular to a method for evaluating the steering efficiency of an automobile driver. Background technique

[0002] Various manipulations of the car are usually done by the driver. As people have more and more requirements for car handling performance, especially for the driver's steering comfort, it is becoming more and more important to conduct a comprehensive and objective evaluation of the steering comfort of the car. Therefore, how to evaluate the steering comfort Evaluation has become one of the hotspots in the field of automotive steering technology. So far, the method of using the driver's physiological characteristics to objectively evaluate the steering comfort of the car has been limited due to the complexity of physiological characteristic signal extraction and analysis and the fluctuation of the driver's physiological and psychological state. The present invent...
