Problems solved by technology
At present, the obstacle avoidance of the car is still at the stage that requires human control. The success rate of obstacle avoidance and whether the car can avoid obstacles perfectly are mostly related to the operator's control technology. For complex terrain or harsh environment conditions, It is often difficult for the operator to realize that the car successfully avoids obstacles

The invention discloses an automatic obstacle avoidance device and a control method for an intelligent vehicle. The obstacle avoidance device includes a controller, and a distance measuring sensor A, a distance measuring sensor B, a distance measuring sensor C, a distance measuring sensor D, and a distance measuring sensor respectively connected to the controller. The distance measuring sensor E and the encoder for measuring the angular displacement of the wheel, wherein the distance measuring sensor A is located in the middle of the front of the car and faces straight ahead, the distance measuring sensor B is located on the right side of the front of the car and faces the right front, and the distance measuring sensor C is located at the front of the car The distance measuring sensor D and the distance measuring sensor E are arranged on the left and right sides of the vehicle body and facing the two sides of the road. The controller obtains the sensor signal on the vehicle body, comprehensively analyzes the state information of the ranging sensor and the encoder data, thereby judging the location of the obstacle and the running state of the smart car, controls the steering angle of the smart car and the driving distance after turning, and realizes obstacle avoidance Function.
Description
technical field [0001] The invention belongs to the technical field of robot automatic obstacle avoidance, and in particular relates to an automatic obstacle avoidance device and a control method for an intelligent vehicle. Background technique [0002] With the rapid development of science and technology, if the car can automatically identify the position of obstacles and take corresponding measures to avoid obstacles when the car is driving automatically, it will be of great significance to the intelligentization of the car in the future. At present, the obstacle avoidance of the car is still at the stage that requires human control. The success rate of obstacle avoidance and whether the car can avoid obstacles perfectly are mostly related to the operator's control technology. For complex terrain or harsh environment conditions, It is often difficult for the operator to realize that the car successfully avoids obstacles. Contents of the invention [0003] The purpose of...
