随着高速公路和汽车的迅速发展，汽车安全技术越来越受到人们的重视。汽车避障系统起辅助的作用，可以对汽车驾驶中的紧急情况进行预警，避免交通事故。所以，智能激光车辆避障系统的研究有着广阔的发展前景和应用，为今后汽车的主控安全控制和无人驾驶汽车奠定了基础。 本课题提出智能激光车辆避障系统的总体方案设计，采用OK6410作为微控制器，包含激光传感器、TFT液晶显示屏和报警模块。系统通过激光传感器实时监控前方目标，并进行跟踪，最终在TFT液晶屏上显示目标的运动轨迹。当被测距离小于系统计算的安全车距，系统则进行预警，提醒驾驶员注意采取减速或制动措施；当被测目标和本车的车距大于安全车距时，行驶安全，则抑制报警。本文包括以下几个方面： （1）建立车辆或行人的运动模型以及车辆避障的安全距离模型。 （2）系统采用卡尔曼滤波与当前统计运动模型相结合的算法，选择合适的矩形门域，进行预测完成目标物的跟踪。 （3）完善车辆预警算法，保障驾驶员的安全，为车辆下步制动打下基础。 最后，对其模型与算法进行仿真，还在硬件OK6410开发板上进行整体系统的验证。系统液晶屏上显示人机界面和跟踪轨迹，实现目标的跟踪和预警，基本符合汽车安全的要求，这对汽车主动安全和智能交通都有积极的意义。总结本文并针对系统不足，指出下一步研究的内容。

The highway and automotive are growing rapidly in China,the car safety has become an increasing attention.Automotive obstacle avoidance system plays an auxiliary role,which can early warn the car driving emergency to avoid traffic accidents.So,research on intelligent laser vehicle obstacle avoidance system has broad prospects for development and application,laying the foundation for future automobile main security control and unmanned vehicles. This paper puts the overall scheme of intelligent laser vehicle obstacle avoidance system design,using OK6410 as micro-controllers,laser sensor,TFT display screen and alarm module.System real-time monitors the front target through the laser sensor to track and TFT display screen is showed the target’s trajectory.when the distance between measured target and the vehicles is less than the computing safe distance,the system need to provide warning to the driver to take appropriate measures as slow down or brake;when this distance is greater than the safe distance,the system inhibit alarm.This paper mainly includes several aspects as follows: Firstly,the vehicle and pedestrian movement model and vehicle obstacle avoidance safety distance model are established. Secondly,the current statistical motion model and Kalman filter algorithm is combined in system,selecting the appropriate rectangle door-related fields to predict and track target. Thirdly,improving vehicle warning algorithm to protect the safety of the driver and lay the foundation for vehicle brake in the next step. Finally,model and algorithm are simulated and the system is verified on hardware OK6410 board.The man-machine interface and the trajectory tracking display on the TFT screen, which achieve the goal of tracking and warning.The system basically meet the safety requirements,which has positive significance in the active safety of vehicles and intelligent transportation.which has a positive meaning for automotive active safety systems and transportation efficiency.Concluding the full text and pointing out the inadequacies of the system and the work of the content in further research.
