A method and device for online identification of driver's steering characteristics

Abstract

The invention discloses an on-line identification method for steering characteristics of drivers. The on-line identification method comprises the following steps: S1, collecting steering data of cars when a plurality of drivers under test drive the cars and steer; S2, analyzing dependency among the steering data collected in the step 1 to obtain characteristic item data capable of describing the steering characteristics of the drivers; S3, clustering the characteristic item data by using a clustering algorithm, and enabling each characteristic item data class to be corresponding to a drive steering type; S4, establishing an off-line identification model by a BP (back propagation) neural network, extracting a weight value and a threshold value, and further establishing an on-line identification model; S5, collecting target steering data of the cars when the drivers under test drive the cars and steer, and identifying the steering characteristics of the drivers under test by the on-line identification model. According to the on-line identification method for the steering characteristics of the drivers, disclosed by the invention, in allusion to the problem that the operations of the drivers are not matched with car responses in the steering process of the cars, the on-line identification model is established, therefore the types of the steering characteristics of the drivers can be accurately identified in real time.

Description

technical field [0001] The invention belongs to the technical field of vehicle control, in particular to a method and device for on-line identification of steering characteristics of a driver. Background technique [0002] The city has a large traffic volume and dense traffic flow, so it is necessary to set up traffic posts to maintain traffic order. Traffic posts are generally set at intersections, and drivers will encounter a road condition similar to a right-angled bend when turning at the traffic post. Although the design concept of modern vehicles already has elements to improve the comfort of the car, it still does not fully consider the comfort of the driver when turning. In addition, in the process of producing vehicles, there are inevitably manufacturing and assembly errors. It will lead to the mismatch between the driver's operation and the car's response when the vehicle is turning, so solving this problem has become the focus of improving the steering comfort of...
