Embodiment 1

[0065] see figure 1 , this embodiment provides a method for personalized lateral assisted driving of an intelligent vehicle, which can be used in the control system of the vehicle and realize the control of the vehicle in various ways. When implementing the method of this embodiment, the method can be designed as a program module and applied in the controller of the vehicle, or the method can be embedded in the software control system of the vehicle itself, and the original software can be updated by updating the program or the like. The system can be upgraded, and the method can also be embedded in new hardware alone, and the hardware can be used as an independent product. Wherein, the intelligent vehicle personalized lateral assisted driving method includes the following steps.

[0066] 1. Collect the running status information and vehicle location information during the driving process of the vehicle. In this embodiment, the running state information can be collected by v...

Embodiment 2

[0113] see figure 2 , this embodiment provides a personalized lateral assistance driving system for an intelligent vehicle, which can be directly installed in an existing vehicle control system, especially can be used in an existing vehicle automatic driving control system. In this embodiment, the intelligent vehicle personalized lateral assisted driving system includes a vehicle-mounted information collection device, a driver's driving style evaluation module, and a vehicle-mounted control device.

[0114] The on-vehicle information collection device is used to collect the running status information and vehicle location information during the driving process of the vehicle. The running state information includes the vehicle's longitudinal speed, lateral speed, acceleration, steering wheel rotation speed, yaw rate, and vehicle heading angle. When the driver starts to drive the vehicle, the on-board information collection device collects and stores the running status informatio...

Embodiment 3

[0118] This embodiment provides an automatic driving car, which includes an automatic driving vehicle body, an automatic driving system, and the intelligent vehicle personalized lateral assisted driving system in Embodiment 2. In the intelligent vehicle personalized lateral assisted driving system in Example 2, after the optimal control module calculates the control amount of the steering wheel angle, the information is fed back to the automatic driving system, and the automatic driving system is further realized through the steering system of the automatic driving body. The control of the self-driving car body enables the self-driving car body to perform steering and other operations as required. The self-driving car can meet the individual needs of the driver and make the car more humanized during driving, thereby improving the driving comfort of the driver on the one hand and improving the driving safety of the vehicle on the other hand.

Abstract

The invention discloses a personalized lateral auxiliary driving method and system of an intelligent vehicle. The method comprises the steps of collecting running state information and vehicle position information in a vehicle running process; collecting driving behavior characteristic parameters of a driver of the vehicle, and calculating an aggressive degree of a driving style of the driver according to a driving speed, a mean value of an acceleration change rate absolute value and a mean value variable of a steering wheel rotating speed; establishing a vehicle dynamics model; simulating thebehavior of the driver for predicting a path, and predicting the vehicle behavior in a next time period; constructing a cost function to quantify a lateral deviation between an optimal path and the future behavior of the vehicle; and solving a steering wheel angle control quantity of the vehicle by minimizing the cost function, and making the steering wheel angle control quantity act on a steering system of the vehicle to assist the driver in driving the vehicle. According to the method and the system, driver factors are fully considered so that driving comfort can be improved, the driving ismore humanized, and the driving safety and comfort are improved.

Description

technical field [0001] The present invention relates to an assisted driving method in the technical field of intelligent vehicles, in particular to an intelligent vehicle personalized lateral assisted driving method, and also relates to an intelligent vehicle personalized lateral assisted driving system applying the method. Background technique [0002] With the popularization and development of intelligent networked vehicles, consumers have gradually increased their own safety awareness, and their demands for accident prevention have gradually increased. Driving safety has received extensive attention from consumers and vehicle manufacturers. More and more Assisted driving technology is applied to vehicle products and put into the market. [0003] The existing assisted driving system, in the process of driving, obtains the state of the environment, vehicle and driver in real time through various sensors, and through computer processing, it is converted into auxiliary contro...
