Problems solved by technology

However, the current evaluation of driver comfort is mostly subjective, and there is no comfort evaluation system based on the combination of physiological EMG signals and driver control information, so it is impossible to evaluate driver comfort through objective quantitative indicators. formal expression

Embodiment Construction

[0037] The present invention will be further described below in conjunction with the flowchart.

[0038] A method for evaluating the driver's lane-changing comfort based on myoelectricity and manipulation information, which specifically includes the following steps:

[0039] Step 1. Select a number of test drivers, select the main muscles of the neck of the test drivers when turning their heads as the muscle groups to be tested, and use a multi-channel electromyographic signal physiological test recorder as the signal collection facility to measure the strength of each test driver. Information about the activation level of each muscle when the patient performs lane-changing movements.

[0040] When the main force-generating muscles of the neck of the test driver are selected as the muscle groups to be tested, the left sternocleidomastoid muscle, left upper trapezius muscle, right sternocleidomastoid muscle, and right upper oblique muscle are selected. Quadratus muscle was use...

Abstract

The invention discloses a method for evaluating the driver lane change comfort based on myoelectricity and control information. The method comprises the steps that main force exerting muscles on the neck and the back of each tested driver during head turning are selected as muscles to be tested; a multi-channel electromyographic signal testing recorder is adopted as a signal collecting facility for measuring electromyographic information of each muscle of each testee when a lane change action is carried out; then car information collecting equipment is used for reading control data generated under the work condition that the tested drivers complete lane change from a car CAN network; then collected electromyographic signals are subjected to root-mean-square processing, the collected control data is subjected to square deviation processing, and weights are set; finally, the comfort of the drivers in the lane change process is comprehensively determined according to the weights.

Description

technical field [0001] The invention belongs to the field of automobile ergonomics and specifically designs a method for evaluating the driver's lane-changing comfort based on myoelectricity and control information. Background technique [0002] With the gradual increase of the number of cars in our country, in addition to safety, people are more and more focused on the comfort of cars. At the static level, good car comfort is not only related to the material and structure of the car seat, but also closely related to the size of the car interior and the design of the human-computer interface. At the dynamic level, the ride comfort and handling stability of the car directly determine the riding experience of the occupants. In daily lane-changing conditions, driver comfort can be reflected by both vehicle parameter information and driver EMG information. However, the current evaluation of driver comfort is mostly subjective, and there is no comfort evaluation system based on...
