Embodiment Construction
[0040] The present invention will be further described below in conjunction with accompanying drawing:
[0041] refer to figure 1 , is a schematic diagram of the installation position of the self-vehicle components and the positional relationship between the self-vehicle and the rear vehicle in the present invention. refer to figure 2 , is a schematic diagram of device circuit connection of the present invention. The rear vehicle motion state tracking and predicting device of the present invention includes a vehicle 5, and an image processor 1 is installed under the vehicle instrument panel. The image processor 1 adopts an ARM9 processor, which is encapsulated in a metal box and communicates with the outside world through wires. Signal transmission. The specific model of the ARM9 processor 7 is S3C2410. figure 1 Among them, the rear vehicles include the vehicle 7 located directly behind the own vehicle, the vehicle 6 located behind the left side of the own vehicle and in ...

The invention relates to the field of vehicle active safety and in particular relates to a device and a method for predicting the motion state of a vehicle behind by tracing. The device for predicting the motion state of the vehicle behind by tracing comprises the vehicle, an image processor, a camera fixed in the middle of the outer side of the rear windshield of the vehicle, a lane line sensor for detecting the vehicle and the lane line of a lane where the lane runs, and a red signal lamp fixed on the instrument panel of the vehicle; the camera faces the back of the vehicle; the lane line sensor is fixed in the middle of the outer side of the front windshield of the vehicle; the signal input end of the image processor is electrically connected with the vehicle speed signal wire of the vehicle, the signal output end of the camera and the signal output end of the lane line sensor, respectively; the signal output end of the image processor is electrically connected with the red signal lamp.
Description
technical field [0001] The invention relates to the field of automobile active safety, in particular to a device and method for tracking and predicting the motion state of a rear vehicle. Background technique [0002] Lane changing is a common operation behavior in the driving process. During the driving process, the driver needs to obtain the movement status of the vehicles around the vehicle and the positional relationship with the vehicle in a timely manner, so as to ensure that the vehicle is in a safe driving environment. At this stage, due to the imperfection of the driver assessment system in our country, there are obvious differences in the quality of drivers, and dangerous driving behaviors such as sudden steering of surrounding vehicles often occur during driving. In particular, if the vehicle is in the lane-changing preparation stage, and the vehicle behind the vehicle suddenly changes lanes to the target lane of the vehicle, the following time distance between th...
