Problems solved by technology
[0005] The existing steer-by-wire control technology is basically based on the basic idea of "human adapts to the car", and does not take into account the differences in the driver's driving operation process. The driver is forcibly interfered in the steering operation process, which cannot satisfy the driver's needs. desired driving experience

[0072] In order to clearly and completely describe the technical solution of the present invention and its specific working process, in conjunction with the accompanying drawings, the specific implementation of the present invention is as follows:
[0073] like figure 1 As shown, the present invention provides an intelligent steer-by-wire control method that integrates the driver's personality. First, the characteristic parameters of the steering system are extracted through the collected data information, and then the driver's personality data and operation risk are respectively obtained through the corresponding characteristic parameters. Then, according to the obtained data, make the corresponding steering control decision, and finally execute the corresponding decision.
[0074] The specific control process of the intelligent steering-by-wire control method is as follows:
[0075] Step 1: Data collection and feature parameter extraction, such as figure 2 Shown:

The invention provides an intelligent steer-by-wire control method that integrates the driver's personality. First, the characteristic parameters of the steering system are extracted through the collected data information, and then based on the corresponding characteristic parameters, K-means cluster analysis and BP neural network The network method identifies the driver's personality data, and judges the operational risk data through logical operations, and then uses the fuzzy decision-making method to make a decision to intervene in steering, not to intervene in steering, or to take over steering control based on the obtained data, and finally executes the corresponding decision. When the control command is received, the vehicle controller continues to integrate the driver's personality and the risk of operation, and corrects the steering angle transmission ratio. The invention integrates the driving characteristics of drivers with different driving characteristics to realize the humanized control of "the car market adapts to people", and can predict the stable state of the vehicle, intervene in time for dangerous steering behavior, and effectively improve the active safety of the vehicle.
Description
technical field [0001] The invention belongs to the technical field of steering-by-wire control, and is especially suitable for intelligent driving, and in particular relates to an intelligent steering-by-wire control method that integrates the driver's personality. Background technique [0002] With the continuous development of electronic technology and control-by-wire technology, its application in the automotive field is becoming more and more extensive. The steer-by-wire vehicle is an important achievement based on this electronic technology and control-by-wire technology. The steer-by-wire vehicle cancels the mechanical connection between the steering wheel and the steering gear. The steering wheel's steering commands are collected by the steering wheel angle sensor and the steering wheel torque sensor, and the steering motor is controlled to drive the steering gear to rotate to complete the corresponding vehicle steering task. Steering by wire technology improves the ...
