摘　　要：针对常规的汽车倒车控制系统中测试精度不足的问题,设计基于激光测距技术的汽车倒车控制系统。在原有系统硬件的基础上,引用激光器,设计相应的激光发射电路和激光接收电路,通过激光测试的距离感知汽车倒车的周围环境,在硬件设计完成的基础上,制定控制规则,以此为依据,采用模糊控制法实现汽车倒车控制。测试结果表明:与常规的汽车倒车控制系统相比,设计的基于激光测距技术的汽车倒车控制系统测试精度更高,该系统优于常规的倒车控制系统。Aiming at the problem of insufficient test precision in conventional vehicle reversing control system,a vehicle reversing control system based on laser ranging technology is designed. On the basis of original system hardware,the corresponding laser transmitting circuit and laser receiving circuit are designed with reference to the laser,and the distance of the laser test is used to perceive the surrounding environment of the car reversing. On the basis of the completion of hardware design,the control rules are formulated. On this basis,the fuzzy control method is adopted to realize car reversing control. The test results show that compared with the conventional vehicle reversing control system,the designed vehicle reversing control system based on laser ranging technology has higher measurement accuracy,and the system is superior to conventional vehicle reversing control system.
