A method for anti-collision of unmanned vehicles

Abstract

The present invention relates to the field of unmanned vehicles, that is, the field of unmanned driving or automatic driving, and more particularly, relates to a method for avoiding collisions of unmanned vehicles. The method includes: collecting obstacle information around the unmanned vehicle; screening the first target obstacle according to the information of the unmanned vehicle and the obstacle; comparing whether the first target obstacle is located in the unmanned vehicle within a safe distance; if the first target obstacle is within the safe distance and the unmanned vehicle is in motion, brake the unmanned vehicle; if the first target obstacle is within the Within the safe distance, and the unmanned vehicle is in a stationary state, keep the unmanned vehicle stationary. This method can accurately screen the target, and can realize the slow braking of the unmanned vehicle, avoiding the braking and causing the vehicle to roll over.

Description

technical field [0001] The present invention relates to the field of unmanned vehicles, and more specifically, to a method for avoiding collisions of unmanned vehicles. Background technique [0002] In recent years, my country's auto industry has developed rapidly, and the application of unmanned vehicles has become more and more extensive, but its arrival will also bring a series of safety problems. Since driverless cars are controlled by computers, some emergencies on the road in reality may cause misjudgments by computers, causing driverless cars to lose control and causing traffic accidents. [0003] At present, under low-speed operating conditions (0-20km / h), the actuator can respond to the maximum deceleration output, and the overall stability of the vehicle body is relatively good; but under normal operating conditions (20-40km / h), there is no People and vehicles often apply full brakes to high-risk obstacles while driving, which often leads to dangerous scenarios su...

Since driverless cars are controlled by computers, some emergencies on the road in reality may cause misjudgments by the computer, causing driverless cars to lose control and causing traffic accidents

[0003] At present, under low-speed operating conditions (0-20km / h), the actuator can respond to the maximum deceleration output, and the overall stability of the vehicle body is relatively good; but under normal operating conditions (20-40km / h), there is no People and vehicles often apply full brakes to high-risk obstacles during driving, which often leads to dangerous scenarios such as vehicle rollovers

[0004] Existing unmanned vehicles cannot perform slow braking according to the vehicle speed and TTC (Time To Collision, collision time). When the vehicle decides to brake, it can only implement full braking, which is prone to dangerous scenarios such as rollover.

In addition, the existing unmanned vehicles cannot accurately screen the target obstacles, and often cause false braking, resulting in a waste of energy
