技术领域 technical field
本发明涉及交通技术领域，特别涉及一种超车辅助系统。 The invention relates to the technical field of traffic, in particular to an overtaking auxiliary system.
背景技术 Background technique
汽车保有量近年来增加迅猛，交通道路的发展就显的有些缓慢，道路拥堵已然成为当今很严重的一个城市发展现象，同时也带来了极大的交通安全问题。如何能有效解决道路拥堵问题并降低事故率，各个国家各个城市都在不断的制定出相应的解决措施，但是效果并不十分理想。 The number of cars has increased rapidly in recent years, and the development of traffic roads has been somewhat slow. Road congestion has become a very serious urban development phenomenon today, and it has also brought great traffic safety problems. How to effectively solve the road congestion problem and reduce the accident rate, various countries and cities are constantly formulating corresponding solutions, but the effect is not very satisfactory.
在道路行驶中，有时一辆大卡车行驶缓慢，但是后方车辆无法看到卡车前方道路空旷的路况，不敢超车，这可能就会造成后方车辆积压。如果盲目超车，则有可能造成不可估量的损失。如果能及时判断行进中的汽车其前车前方的路况，给出正确的超车判断，则可能减少很多拥堵现象，提高车辆的通行量，并能减少因超车不当而引起的道路交通事故。 When driving on the road, sometimes a large truck is moving slowly, but the vehicles behind cannot see the open road ahead of the truck, and dare not overtake, which may cause a backlog of vehicles behind. If you overtake blindly, it may cause immeasurable losses. If it is possible to judge the road conditions in front of the vehicle in front of it in time and give a correct overtaking judgment, it may reduce a lot of congestion, increase the traffic volume of vehicles, and reduce road traffic accidents caused by improper overtaking.
发明内容 Contents of the invention

具体实施方式 detailed description
下面对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。 Specific embodiments of the present invention will be further described in detail below. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
该超车辅助系统在前后两辆车上都进行安装，包括：主控模块1、DSR专用短程通信模块2、报警器3、转向灯4、显示屏5、图像传感器6、车距传感器7和车速传感器8；主控模块1设有超车按钮9，用于向本车的主控模块发9出超车信号请求；前后两辆车的主控模块1通过两辆车的DSRC专用短程通信模块相互连接，前车的图像传感器6的前方路况信号在两辆车的主控模块1之间相互交换，并通过显示屏5显示，后车的车距传感器7和车速传感器8也分别向后车的主控模块1发送信号，然后由主控模块1进行判断是否控制报警器3、转向灯4工作。 The overtaking assist system is installed on both front and rear vehicles, including: main control module 1, DSR dedicated short-range communication module 2, alarm 3, turn signal 4, display screen 5, image sensor 6, vehicle distance sensor 7 and vehicle speed Sensor 8; the main control module 1 is provided with an overtaking button 9, which is used to send an overtaking signal request to the main control module of the vehicle; the main control modules 1 of the front and rear two vehicles are connected to each other through the DSRC dedicated short-range communication modules of the two vehicles , the front road condition signal of the image sensor 6 of the front car is exchanged between the main control modules 1 of the two cars, and is displayed through the display screen 5, and the distance sensor 7 and the speed sensor 8 of the rear car are also sent to the main control module 1 of the rear car respectively. The control module 1 sends a signal, and then the main control module 1 judges whether to control the alarm 3 and the turn signal 4 to work.
超车按钮置9于驾驶员左手操作区域内，方便驾驶员操作。这是向主控模块1发出的超车指令。 The overtaking button is placed 9 in the driver's left hand operation area, which is convenient for the driver to operate. This is an overtaking command sent to the main control module 1 .
显示屏5置于驾驶员视线范围内的仪表盘附近，方便驾驶员查看主控模块1输出的是否可超车的信息。报警器3为蜂鸣器，如不可超车，则发出蜂鸣声给出警告，显示屏显示红色信息。如果可超车，转向灯4开启的是左转向灯，显示屏显示绿色信息。 The display screen 5 is placed near the instrument panel within the driver's line of sight, so that the driver can check the information output by the main control module 1 whether it is possible to overtake. Alarm 3 is buzzer, as can not overtake, then sends buzzer and gives warning, and display screen shows red message. If overtaking is possible, what turn signal 4 is turned on is the left turn signal, and the display screen shows green information.
主控模块1能够通过DSRC专用短程通信模块2获得前车的图像传感器数据，可了解前车前方的路况情况。前车的图像传感器数据即为前车的前方是否有行进中的车辆，如有，则主控模块1判断不可超车。 The main control module 1 can obtain the image sensor data of the vehicle in front through the DSRC dedicated short-range communication module 2, and can understand the road conditions in front of the vehicle in front. The image sensor data of the vehicle in front is whether there is a moving vehicle ahead of the vehicle in front, and if so, the main control module 1 judges that overtaking is not allowed.
车速传感器8传给主控模块1自身的车速和其它车辆的车速传感器8发来的车速，如主控模块1判断相邻车速不符超车条件，则不可超车。 The vehicle speed sensor 8 transmits the vehicle speed of the main control module 1 itself and the vehicle speed sent by the vehicle speed sensors 8 of other vehicles. If the main control module 1 judges that the adjacent vehicle speed does not meet the overtaking condition, then it cannot overtake.
多个车距传感器7传给主控模块1周围邻近车辆的车距，如有前车距离或对向车距低于安全车距，则主控模块1判断不可超车。 A plurality of vehicle distance sensors 7 transmit the vehicle distances of adjacent vehicles around the main control module 1. If there is a distance between vehicles in front or opposite vehicles that is lower than the safe distance between vehicles, then the main control module 1 judges that overtaking is not allowed.
该超车辅助系统利用车车之间的短程通信，获得前车前方的路况情况，以及前方和对向车辆的车距、车速情况，对是否可超车做出判断。如有安全风险不适合超车，则报警器发出报警并在显示屏上用红色显示相应信息，如可超车，转向灯开启并通过显示屏用绿色显示相应信息，因而能够提高行车安全性，降低超车事故的发生。 The overtaking assistance system uses short-range communication between vehicles to obtain the road conditions in front of the vehicle in front, as well as the distance and speed of the vehicle in front and oncoming vehicles, and make a judgment on whether overtaking is possible.
