Emergency obstacle avoiding system for automatic driving automobile

Abstract

The invention relates to an emergency obstacle avoiding system for an automatic driving automobile. The emergency obstacle avoiding system comprises at least two main exterior detecting units, at least two auxiliary exterior detecting units and an interior control device; the main exterior detecting units and the auxiliary exterior detecting units are separately and electrically connected with theinterior control device; the main exterior detecting units are uniformly distributed on the front end surface and the rear end surface of the automobile surrounding the axis of the automobile; and the auxiliary exterior detecting units are uniformly distributed on the left side outer surface and the right side outer surface of the automobile surrounding the axis of the automobile. According to the emergency obstacle avoiding system disclosed by the invention, on one hand, during distance measurement and determination operation on obstacles, the capacity of disturbing the detection operation by external environment is effectively overcome, so that the accuracy and the reliability of the distance measurement and determination operation are improved, and the capacity of recognizing the typeof the obstacles is also improved; and on the other hand, the emergency obstacle avoiding system has good structural strength and structural adjusting flexibility, so that according to the using requirement, comprehensive detection can be performed on the obstacles on the periphery of a current automobile within a 360-degree range.

Problems solved by technology

[0002] At present, in unmanned vehicles, aircrafts and other highly autonomous operating equipment, in order to improve the safety and reliability of the autonomous operation of the equipment, such equipment is often installed on such equipment for active detection and ranging of obstacles. Obstacle avoidance device, through which to detect obstacles in the running track of unmanned vehicles, aircraft and other highly autonomous operating equipment, and guide unmanned vehicles, aircraft and other highly autonomous operating equipment to avoid obstacles, However, in actual use, it is found that the currently used obstacle avoidance devices are often composed of a number of ultrasonic ranging devices evenly distributed on the side surfaces of high-autonomous operating equipment such as unmanned vehicles and aircrafts. However, during the detection process, the detection signal is susceptible to interference from the external environment, which affects the effective distance of the ranging operation and the accuracy of obstacle detection and judgment, and the judgment of the obstacle type cannot be realized, so it cannot be effectively realized. Distinguish between pedestrians and objects, resulting in relatively low safety during obstacle avoidance operations. On the other hand, in the detection operation, the working position and working state of the obstacle avoidance device cannot be flexibly adjusted according to the needs of use, which further affects the current state of the art. The flexibility and detection accuracy of using the obstacle avoidance device cannot meet the needs of flexible detection of obstacles around the vehicle according to the actual operation of the vehicle. Therefore, in response to this problem, a new type of obstacle avoidance device needs to be developed to meet practical needs
