1. 研究目的与意义(文献综述)

in recent years, the automobileindustry has begun to show a huge wave of innovation, rapidly moving towardselectrification, networking and intelligence. the development of self-drivingcars will have a profound impact on the automotive industry and the transportationindustry. to achieve automatic driving, the environment-aware system is one ofthe key technologies. the self-driving vehicle environment sensing system needsto quickly acquire relevant data information of the driving environment, suchas a target within a certain range of the vehicle, a guide of the lane line,and traffic road information; the self-driving vehicle control system needs tofeed back information according to the environment sensing system. combinedwith high-precision navigation system, the corresponding path planning anddecision-making are made to achieve safe automatic driving. at present,auto-driving technology is rapidly developing, and the use of environmentalsensing systems is becoming more and more common.

at the same time, the redundantdesign of self-driving cars is also rapidly developing. the redundant design ofthe automatic driving system generally includes power supply, positioning,sensing, controller and actuator. the redundant design is mainly to avoidserious safety accidents caused by the failure of the autopilot system due tothe failure of a certain component to ensure the safety of pedestrians andpassengers.

of course, communicationbetween components is also important. due to the high-performance,high-reliability communication mechanism of the can bus, it has been widelyused in the field of automotive electronics. the can protocol is used forcommunication between various components in automobiles to replace expensiveand bulky distribution harnesses. therefore, the can bus also plays animportant role in the entire autonomous driving system. the signal transmissionof the environment-aware sensor on the self-driving car is also realized bycan.
