Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039]An embodiment of the present invention is a lane keeping method for a vehicle driven by distributed motors and the vehicle, and the vehicle of the present invention includes an image acquisition device and a lateral acceleration sensor. There is at least one image acquisition device, which is arranged on the left side of the vehicle, and can capture the left identification line of the lane where the vehicle is located. Through image processing technology, the distance from the left side of the vehicle to the identification line on the left side of the lane can be obtained.

[0040] As other embodiments, there may be several image acquisition devices, which are arranged at other positions of the vehicle. The specific principle is to be able to obtain the image of the lane identification line, and obtain the positional relationship between the vehicle and ...

Abstract

The invention relates to a lane keeping method for a distributed motor drive-based vehicle and the vehicle. Based on an image acquisition device and an image analysis and processing technology, whether the vehicle deviates from a lane or has a tendency to deviate from the lane is judged, and the torque of distributed drive motors is adjusted in real time according to the deviation amount, therebygenerating a yaw moment around the center line of the drive axle of the vehicle perpendicular to the ground to drive the vehicle to return to the lane, thereby realizing that the vehicle keeps runningat the lane. The lane keeping method for the distributed motor drive-based vehicle can correct the lane deviation accurately and quickly, and the response time is short, and control mechanisms adoptthe original parts, which reduces the cost.

Description

technical field [0001] The invention relates to a lane keeping method for driving a vehicle based on a distributed motor and the vehicle, belonging to the field of intelligent assisted driving of automobiles. Background technique [0002] In recent years, with the continuous increase of car ownership, the total number of traffic accidents has continued to increase. Driving safety has become a key issue in the field of social transportation and automobiles. In order to improve driving safety and reduce the driver's driving burden, Advanced Driving Assistance System (Advanced Driving Assistance System, ADAS) has been extensively researched and gradually applied. [0003] As the main branch of ADAS, there are many forms of vehicle lateral driving assistance systems, among which the Lane Keeping Assistance System (LKAS) is designed for the driver's lane departure due to fatigue or inattention. Specifically, through sensing or imaging technology (such as high-definition imaging...
