Problems solved by technology

Ordinary passenger cars need less space when turning than passenger cars, but in special traffic environments, such as vertical curves and there are obstacles such as utility poles and steps inside the curve that are likely to scratch the vehicle, if the driver When the position of the vehicle is improperly grasped or the obstacle is not noticed, it is very easy to cause a scratch accident

Embodiment Construction

[0030] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Such as Figure 1-Figure 4 As shown, a kind of anti-scratch device when turning a vehicle described in this embodiment includes:

[0032] Two laser scanning radars 4 and 5 are respectively installed on the left and right sides of the front bumper of the vehicle to detect the traffic environment information around the vehicle, and identify whether the vehicle is located on a curve with obstacles on the inside according to the scanning results;

[0033] The steering wheel angle sensor is installed on the steering wheel steering shaft of the vehicle, and is used to obtain the steering wheel angle data of the vehicle;

[0034] The intelligent CAN converter can obtain the steering signal data on the CAN bus of the vehicle body, and the steerin...

Abstract

The invention provides an anti-scratch device and method used during vehicle turning. The anti-scratch device comprises two laser scanning radars installed on the left side and the right side of a front bumper of a vehicle correspondingly, a steering wheel angle sensor installed on a steering shaft of a steering wheel of the vehicle, an intelligent CAN converter, an alarm prompt unit and a processing unit. The anti-scratch device and method used during vehicle turning have the beneficial effects that the laser scanning radars are used for obtaining the road environment information around the vehicle, laser radar detection is not disturbed by ambient light, and the recognition precision is high. Meanwhile, a vehicle track is determined according to the angle of the steering wheel, the next position of the vehicle is further determined, and a system has high predictability; and the method is simple, and the advanced active safety system is obtained.

Description

technical field [0001] The invention relates to the technical field of automobile active safety, in particular to an anti-scratch device and method when a vehicle turns. Background technique [0002] Scratching is a common form of traffic accidents in the driving process. The driver often fails to notice the obstacles in the field of vision, or does not grasp the positional relationship between the obstacles and the vehicle accurately, or the obstacles are located in the blind area of ​​the driver's vision. lead to a crash accident. Since the driver is on one side of the vehicle, the driver’s ability to perceive the position of the body on the other side is different. At the same time, due to the difference in the size of the vehicle, although the principle of the operating mechanism of the vehicle is similar, it is reflected in different models, and its operation is also different. Big difference, typical, such as when a bus is turning, the turning will cause the bus to cr...
