Embodiment Construction

[0101] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0102] refer to figure 1 , which shows a flow chart of the steps of a vehicle driving control method according to an embodiment of the present invention, which may specifically include the following steps:

[0103] Step 101, detecting multiple driving states of the vehicle.

[0104] In practical applications, a variety of sensors are integrated in the vehicle, such as speed sensors, acceleration sensors, angular velocity sensors, cameras, etc., and these sensors can be called to detect the driving state of the vehicle.

[0105] In one example, the speed sensor can detect the driving speed of the vehicle as the driving state.

[0106] In another example, the camera can detect the driving direction, the first distance and the seco...

Abstract

Embodiments of the present invention provide a vehicle driving control method, device, and vehicle. The method includes: detecting multiple driving states of the vehicle, the multiple driving states including multiple driving directions; The position is driven along the multiple driving directions for preview, and multiple preview paths are obtained; according to the multiple preview paths, multiple turns of the vehicle traveling from the original position to the target path in the lane are fitted path; using the plurality of turning paths to calculate the change information of the steering wheel angle; adjusting the driving direction according to the change information of the steering wheel angle, so as to control the vehicle from the original position along the turning path to the target path drive. The embodiment of the present invention enables the vehicle to return to the target path of the lane, avoids adjustment based on empirical values, ensures driving stability, effectively alleviates the problems of overshoot and vibration, and improves the driver's comfort.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle driving control method, device and vehicle. Background technique [0002] With the development of science and technology, the problem of traffic safety has become more and more prominent, and the safety of vehicles has been refined, which can be divided into active safety and passive safety. [0003] In an active safety technology, when the vehicle is driving, if the center position of the vehicle exceeds the center line of the lane by a large amount, the PID (proportion integration differentiation, proportional-integral-derivative) adjustment method is adopted to apply a certain torque to the steering wheel , so that the vehicle turns and returns to the centerline of the lane. [0004] The parameters of the proportional, integral and differential links in PID adjustment are generally set according to experience, the accuracy rate is low, and the value of the param...
