Vehicle fork road segment detection device and detection method

Abstract

The invention relates to the vehicle safety auxiliary driving technology and discloses a vehicle fork road segment detection device and a detection method. The device comprises a vehicle-mounted industrial personal computer, a vehicle speed sensor, a multiline laser radar sensor, a steering wheel steering angle sensor and a display; the multiline laser radar sensor is used for detecting the height of the left road side and the right road side of a road portion in front of a vehicle and the distance between the vehicle and the left road side and the right road side; the steering wheel steering angle sensor is used for detecting the vehicle steering angle in real time; the vehicle-mounted industrial personal computer calculates and draws according to the vehicle steering angle, the vehicle speed, the height of the left road side and the right road side and the distance between the vehicle and the left road side and the right road side to enable a vehicle driving predicted track curve and estimation curves of the left road side and the right road side of the front fork road segment to be obtained; the display is used for displaying the estimation curves of the left road side and the right road side and the vehicle driving predicted track curve in real time. The vehicle fork road segment detection device has the advantages of enabling the estimation curves of the left road side and the right road side and the vehicle driving predicted track curve at the fork road segment to be obtained, reminding a driver to appropriately operate, relieving driver judgment burden and reducing misjudgment possibilities.

Description

technical field [0001] The invention relates to vehicle safety assisted driving technology, in particular to a detection device and detection method for a road section at a vehicle fork. Background technique [0002] According to the data in the Ministry of Public Security's traffic accident statistics annual report in recent years, traffic accidents on fork roads often occur. Due to the large traffic volume, fast speed and large blind spot of the driver's vision on this road section, the driver is likely to make an improper subjective judgment and take a steering operation with too large or too small a steering range, which puts the driving vehicle in a potential collision or In danger of tipping over. When the steering angle is too large, it is easy to cause the vehicle to rush out of the fork, and when the steering angle is too small, the vehicle cannot pass the fork smoothly. If the line shape and curvature of the fork in front of the road are predicted in advance, com...

Problems solved by technology

Theoretically, GPS technology can be used to perceive the line shape and curvature of the road fork ahead in advance, but in actual promotion and use, it is necessary to measure and store all the information of the road fork in advance. This process is too much work, so it cannot be widely used
