Integration And Experimental Study Of Automatic Driving System For Bus

With the rapid development of science and technology, the automobile industry presents a good development prospect. Especially, the application of new technology and new equipment, and the automatic driving technology have gradually entered people's vision. The automatic driving system of bus planning and design is essentially in order to escape from the wrong operation of the driver, automatically perceive the hidden danger in driving, reasonably plan and control, and avoid the occurrence of safety accidents to the greatest extent. Based on the actual requirements of bus automatic driving integration, combined with the characteristics of bus, this paper studies the system architecture and core control technology of automatic driving technology on bus. In this paper, multi-sensor data fusion, high-precision positioning, secondary path planning and other control technology means are determined, and then the perception system, decision-making system, execution system are designed and implemented to complete the design of automatic driving bus. Finally, the function, performance, reliability and other aspects of the designed automatic driving bus are tested. The test results show that the vehicle meets the basic actual needs and the expected design objectives, and can realize L3 level automatic driving under the conditions of low-speed closed Park, expressway and urban expressway.
