Abstract

The invention provides a method and system for controlling an automatic driving vehicle. The method includes the steps that when an obstacle occurring in a detection area of the vehicle is collected,a first straight line is obtained according to a first point on the vehicle and a second point on the obstacle; a second straight line is obtained according to a third point on the obstacle, and the angle formed between the second straight line and the first straight line through the third point is a preset angle; the second straight line is translated by a preset distance in the direction of thevehicle, and the area of the detection area overlapping with the side, close to the vehicle, of the second straight line is a driving area of the vehicle. The method maximizes the calculated safe driving area of the vehicle as much as possible to ensure that the vehicle does not collide with obstacles when driving in this area. At the same time, if the number of obstacles is more than one, the driving area of the vehicle can still be calculated, so that the driving safety of the vehicle and the economy and rationality of the route are ensured.

Description

technical field [0001] The present invention relates to the field of automatic driving vehicles, in particular to a control method and system for automatic driving vehicles. Background technique [0002] At present, with the gradual development of the field of self-driving vehicles, intelligent vehicles can automatically calculate the safe driving area of ​​the vehicle according to the calculation method and system of the safety division driving area configured on it. The existing intelligent vehicle driving area calculation methods are as follows: figure 1 As shown, 1' is the vehicle, 2' is the obstacle, the arc area ABC is the detection area of ​​the vehicle 1', and the circle R is the obstacle area occupied by the obstacle 2' set by the vehicle. An area ABD is defined as a drivable area by drawing a tangent line AD to a circle R at the midpoint A of the front end of the vehicle 1'. [0003] However, if two obstacles 2' are detected in front of the vehicle 1', this method...
