Abstract

The invention relates to a method for pre-estimating vehicle trace and evaluating lane deviation, for overcoming the defect of the existing technique not fully reflecting true behavioral characteristic of a driver, announcing a method for evaluating the danger of lane deviation based on behavioral simulation of a driver, using the image sensor-collected lane mark line information of front road and combining the vehicle sensor-provided information such as automobile speed, acceleration, and turning state, to simulate the foreseeing action of the driver (i.e. as driving, the driver controls the present driving of the automobile according to the front road information), forecasting an expected running trace of the automobile in a future period of time, and evaluating the danger of lane deviation with respect to the relative position of the expected running trace and the front road mark lines, thus judging if a lane deviation accident will happen. If the danger of the lane deviation exceeds a certain threshold value, it can give out lane deviation early warning information to the driver by sound and vehicle LCD.

Description

Technical field

[0001] The invention relates to vehicle driving trajectory prediction and lane departure evaluation methods. Background technique

[0002] Traffic safety has always been one of the issues that people are most concerned about, and it is directly related to the loss of people's lives and property. On highways, many traffic accidents occur every year due to driver distraction or operational reasons, resulting in serious casualties and property losses. Therefore, it is of great significance to develop intelligent assisted driving systems that use sensor systems to sense road traffic environment information for decision-making and planning, provide driving suggestions to the driver or partially replace the driver in vehicle control operations.

[0003] As a subsystem of the intelligent assisted driving system, the main function of the lane departure warning system is to assist drivers who are overtired or have been driving monotonously for a long time to keep the...
