Problems solved by technology
[0003] The technical problem in the prior art to be solved by the present invention is: because in the prior art, when the automobile is running on the expressway for a long time, the driver is prone to fatigue and causes inattention, especially when automatic transmission and cruise speed control are installed. On the vehicle, the driver is less involved in vehicle manipulation, which is more likely to lead to distraction, easy to ignore the arc changes of the road, causing the vehicle to gradually leave the lane, or collide with the road isolation device, or cut into the side lane, and collide with other vehicles. At the same time, In the case of poor weather conditions, it is not easy to see the road dividing line, which makes driving difficult

Embodiment Construction
[0015] Such as figure 1 with figure 2 As shown, a method for prompting a car to deviate from a road of the present invention includes a process of judging the distance between the car and the marking line on both sides or one side of the road, wherein the judgment of the car and the marking line on both sides or one side of the road There is a step in the process of using the image acquisition device 1 to obtain the graphic characteristic signals of the marking lines on both sides or one side of the road, and the image acquisition device transmits the graphic characteristic signals to a processing device. The processing device judges the distance between the car and the marking line according to the change of the graphic characteristic signal. At the same time, the process of judging the distance between the car and the marking line on both sides or one side of the road also has a method of using the speed sensor to obtain the real-time speed signal of the car. Step, and transmit...

A device for prompting the driver that the car has been offset from the road is composed of at least one image acquiring unit, a single-chip microprocessor, and an audio alarm unit. Its prompting method includes such steps as acquiring the information about the graphic characteristics of the marker line on road, inputting them to said single-chip microprocessor, judging the distance between car and marker line, inputting the car speed from speed sensor to said microprocessor, calculating the variation rate of said distance, and triggering an audio alarm unit when the relation between car speed and its variation rate reaches a predefined value.
Description
Technical field: [0001] The present invention relates to automobiles, in particular to safety devices of automobiles, and particularly to alarm devices of automobiles, and in particular to a method and device for prompting an automobile to deviate from a road. Background technique: [0002] In the prior art, when a car is driving on a highway for a long time, the driver is prone to fatigue and causes inattention. Especially on vehicles equipped with automatic transmission and cruise speed control, the driver is less involved in vehicle manipulation, which is more likely to cause mental stress. Slack, it is easy to ignore the arc change of the road, causing the vehicle to gradually leave the lane, or collide with the road isolation device, or cut into the side lane, and collide with other vehicles. At the same time, it is not easy to see the road separation under bad weather conditions. Line, causing difficulty in driving. Summary of the invention: [0003] The technical problem ...
