[Abstract]:With the rapid development of automobile industry, intelligent automobile has gradually become a new direction of attention in automobile field and major automobile manufacturers. Intelligent vehicle is composed of perception, decision making, control and path planning, among which the perceptual system is the basis of realizing intelligent driving. The sensing system collects the environmental information around the vehicle through the environment sensing sensor, including lane line, pedestrian and vehicle identification object. The main research content of this paper is to build a multi-sensor intelligent cleaning experimental vehicle platform and design the corresponding environment awareness system algorithm to realize the function of environment sensing system. Installation of cameras, long-range millimeter-wave radar, short-range millimeter-wave radar and ultrasonic radar environment sensing sensors in intelligent cleaning experimental vehicles, The object detection around the vehicle around 360 擄and the recognition function of the front lane are realized. Based on the CAN bus technology of the vehicle, the original data of the obstacle detected by the millimeter wave radar is obtained. The bubbling filtering and time domain filtering algorithms for data preprocessing are designed to realize the stable detection and tracking of the target. Data preprocessing algorithm is also the basis of multi-sensor data fusion algorithm. The algorithm is designed for sensor level and center level data fusion structure in structured road. The data fusion algorithm is designed to improve the detection probability and the reliability of physical information of the object. Then the fusion object is tracked by Kalman filter to realize the function of detecting and tracking the object in front of the vehicle. Finally, the environment sensing system of the intelligent cleaning experimental vehicle is tested. In structured roads, pedestrians, vehicles and bicycles were placed in front of the experimental vehicles. The test results show that the multi-sensor data fusion algorithm designed in this paper can stably identify the tracking object and improve the reliability of the physical information of the object. The test results show that the data preprocessing algorithm designed in this paper can stably identify and track the bicycle target object; in addition, the camera sensor in front of the experimental vehicle can recognize the lane line, thus realizing the environment sensing system function of the intelligent cleaning experimental vehicle. Provide all-round environmental information for the vehicle controller to ensure the safe driving of the vehicle.
