Embodiment Construction

[0025] see figure 1 , is an embodiment of the lane keeping control method of the present invention.

[0026] The lane keeping control method of this embodiment includes the following steps:

[0027] Step S11: receiving the signal of turning on the lane keeping switch;

[0028] Step S12: Collect road condition information and vehicle body information, and control the active steering system to adjust the traveling direction of the vehicle according to the road condition information and vehicle body information;

[0029] Step S13: During the above process of adjusting the direction of travel of the vehicle, if an operation switching signal is received, the lane keeping system is turned off, and the driver controls the vehicle to drive; if a torque applied by the driver to the steering wheel is received signal, then control the active steering system to offset the torque.

[0030] In the lane keeping control method in this embodiment, in the process of adjusting the traveling ...

Abstract

The invention provides a lane-keeping control method and a lane-keeping system. After the lane-keeping system receives opening signals of a lane-keeping switch, a lane identifying device collects road information, a car body information collecting device collects car body information, and a lane-keeping control device controls an initiative steering system to adjust the traveling direction of a car according to the road information and the car body information. In the process of adjusting the traveling direction of the car, if the lane-keeping control device receives operation switching signals, the lane-keeping system is turned off, and a driver controls traveling of the car; if the lane-keeping control device receives torque signals of applying torque on a steering wheel, the lane-keeping control device controls the initiate steering system to offset the torque. The lane-keeping system conducts analysis treatment on the operation of the driver in the process of adjusting the traveling direction of the car and can conduct corresponding treatment on drivers' different operation motions on the car.

Description

technical field [0001] The invention relates to a safety driving assistance system, in particular to a vehicle lane keeping system and a lane keeping control method. Background technique [0002] With the continuous development of economy and transportation, automobiles have become an indispensable means of transportation for people. However, with the continuous improvement of the utilization rate of automobiles, the traffic accident rate also shows an increasing trend year by year. According to statistics, among all motor vehicle accidents, traffic accidents caused by lane departure account for 20% of all traffic accidents. Thirty-seven percent. It can be seen from this data that lane departure accidents have seriously affected people's life and property safety. Therefore, in recent years, many research institutions at home and abroad have begun to devote themselves to the research of lane keeping systems. [0003] The prior art discloses a cooperative lane keeping syst...
