Description
本发明属于汽车领域，提供了一种根据道路路牌调节定速巡航的方法以及巡航系统。 The invention belongs to the field of automobiles and provides a method for adjusting cruise control according to road signs and a cruise system.
定速巡航系统(CRUISE CONTROL SYSTEM) 缩写为 CCS ，又称为定速巡航行驶装置， 速度控制系统, 自动驾驶系统等。其作用是：按司机要求的速度合开关之后，不用踩油门踏板就自动地保持车速，使车辆以固定的速度行驶。采用了这种装置，当在高速公路上长时间行车后，司机就不用再去控制油门踏板，减轻了疲劳，同时减少了不必要的车速变化，可以节省燃料。 CRUISE CONTROL SYSTEM (CRUISE CONTROL SYSTEM) is abbreviated as CCS, also known as cruise control. Speed control system, Autopilot system, etc. Its function is: after the switch is pressed at the speed required by the driver, the vehicle speed is automatically maintained without stepping on the accelerator pedal, so that the vehicle can travel at a fixed speed. With this device, when driving on the highway for a long time, the driver does not have to control the accelerator pedal, which reduces fatigue and reduces unnecessary speed changes, which can save fuel.
定速巡航 用于控制汽车的定速行驶，汽车一旦被设定为巡航状态时，发动机的供油量便由电脑控制，电脑会根据道路状况和汽车的行驶阻力不断地调整供油量，使汽车始终保持在所设定的车速行驶，而无需操纵油门。目前 巡航控制系统 已成为中高级轿车的标准装备。 Fixed speed cruise It is used to control the fixed speed of the car. Once the car is set to cruise, the fuel supply of the engine is controlled by the computer. The computer will continuously adjust the fuel supply according to the road conditions and the driving resistance of the car, so that the car will always be maintained. Drive at the set speed without having to operate the throttle. Currently The cruise control system has become the standard equipment for mid- to high-class cars.
现在许多轿车都有速度控制系统。当汽车在长距离的高速公路行驶时，启动速度控制系统就可以自动将汽车固定在特定的速度上，免除驾车者长时间脚踏 油门踏板 之苦。另外，还有节省燃料和减少排放的好处，因为汽车都有对应的经济速度，当驾驶者将速度控制系统调置在经济速度上就可以起到省油的作用。 Many cars now have speed control systems. When the car is driving on a long-distance highway, the start-up speed control system can automatically fix the car at a specific speed, eliminating the driver's long-time pedaling. The bitterness. In addition, there are benefits of fuel savings and reduced emissions, because the car has a corresponding economic speed, when the driver adjusts the speed control system to economic speed, it can save fuel.
虽然定速巡航让驾驶者体验到了舒适和放松，但是在放松的同时，也会让人的注意力不够集中。如果驾驶者过于放松，就不能集中精力于路况上，路边的提示路牌很可能会被忽略，有些重要的限速提示如果没有看到，就很可能违反交通规则，甚至造成交通事故，这样是很危险的。 Although cruise control allows the driver to experience comfort and relaxation, while relaxing, it also makes people's attention less concentrated. If the driver is too relaxed, he can't concentrate on the road conditions. The roadside warning signs are likely to be ignored. Some important speed limit tips, if not seen, are likely to violate traffic rules and even cause traffic accidents. Very dangerous.
