Auxiliary forward track device for vehicle

Abstract

The invention relates to an auxiliary forward track device for a vehicle. The auxiliary forward track device is characterized by comprising a wide angle camera, a forward track image control system, a steering wheel angle sensor and a display, wherein the forward track image control system comprises a forward track calculation unit and a forward track projection unit; the forward track image control system is respectively connected with the wide angle camera and the display; the forward track image control system is connected with vehicle gears, the steering wheel angle sensor and a driver field selection button; the forward track image control system starts the wide angle camera to shot an image in front of the vehicle and transmits the image to the forward track projection unit; the forward track calculation unit calculates a forward track and a range marker line and transmits the forward track and the range marker line to the forward track projection unit; and the forward track projection unit projects the forward track and the range marker line to the image according to a projection transformation relationship between a ground coordinate system and an image coordinate system and transmits the projected forward track and range marker line into the display for display. The auxiliary forward track device can be widely applied to providing accurate reference information for the driver in the forwarding process of a vehicle.

Description

technical field [0001] The invention relates to a vehicle auxiliary device, in particular to a vehicle forward trajectory auxiliary device for providing the driver with reference information of the road ahead. Background technique [0002] When the driver passes some narrow roads, the driver usually cannot accurately judge the width of the road ahead, and the wheels drive out of the road due to misjudgment, or the vehicle gets stuck between the left and right walls or other obstacles on the road. Cause vehicle damage and traffic jams; in addition, during the driving process of vehicles, there are often several vehicles running in rows on relatively wide roads. When two adjacent vehicles are driving, there will be a driving gap in the middle. If the driver cannot predict the width of the traffic interval and directly passes through the traffic interval by force, the vehicle collision may occur due to the narrow traffic interval, resulting in traffic accidents.

[0002] When the driver passes some narrow roads, the driver usually cannot accurately judge the width of the road ahead, and the wheels drive out of the road due to misjudgment, or the vehicle gets stuck between the left and right walls or other obstacles on the road. Cause vehicle damage and traffic jams; in addition, during the driving process of vehicles, there are often several vehicles running in rows on relatively wide roads. When two adjacent vehicles are driving, there will be a driving gap in the middle. If the driver cannot predict the width of this traffic interval, if he directly passes through this traffic interval, it may cause vehicle collision due to the narrow traffic interval, resulting in traffic accidents.
