Problems solved by technology

[0003] The "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" imposes speed limits on different roads based on conditions such as road category, traffic volume, road width, and barrier conditions. Vehicle speeding will cause the driver's vision to become smaller and the driver's reaction The driving distance of the vehicle increases during the time, and the braking distance increases
Increase the probability of accidents, aggravate the severity of accidents, and affect vehicle safety performance
In reality, in the same place, especially on expressways, the speed limit of different lanes may be different, and the existing speeding reminder system cannot provide drivers with accurate speed limit information

Embodiment 1

[0048] The invention provides a vehicle speeding reminder method and system.

[0049] refer to figure 1 , on a high-speed photovoltaic highway, the vehicle speeding reminder method includes a high-speed speed limit acquisition step S1;

[0050] The high-speed speed limit acquisition step S1 includes:

[0051] Step S110, collecting images of the road ahead of the vehicle.

[0052] Use a camera to capture images of the road ahead of the vehicle. The camera can be a camera mounted on the windshield facing the road ahead of the vehicle, or a driving recorder. When the vehicle starts to drive, the camera or driving recorder is automatically activated or artificially Start the operation and take pictures of the road ahead of the vehicle. Of course, it is not limited to these methods.

[0053] Step S120, obtaining the number of lanes and the lane where the vehicle is located according to the image.

[0054] Step S121, acquiring vehicle model information.

[0055] The vehicle mod...

Embodiment 2

[0071] refer to figure 2 , the present invention provides a vehicle speeding reminder method, the vehicle speeding reminder method also includes step S4, obtaining the location information of the vehicle, and judging whether the road where the vehicle is located is a high-speed photovoltaic road; if yes, enter step S1; if not, enter Step S5: Obtain the speed limit value of the vehicle according to the pre-stored electronic map information.

[0072] Adding step S4, the vehicle speeding reminder method of the present invention distinguishes between high-speed photovoltaic roads and non-high-speed photovoltaic roads, and obtains the location information of the vehicle to know whether the vehicle is on a high-speed photovoltaic road or a non-high-speed photovoltaic road. If it is a non-high-speed photovoltaic road, directly Call the speed limit information of the electronic map at this place, and the speed limit information is the speed limit value; if it is a high-speed photovol...

Embodiment 3

[0075] refer to image 3 , the present invention provides a vehicle speeding reminder system, on the high-speed photovoltaic highway, the vehicle speeding reminder system includes:

[0076] The road information collection module 110 receives an activation command and collects images of the road ahead of the vehicle.

[0077] The road information collection module 110 obtains the road image in front of the vehicle captured by the camera in real time. It can be understood that there can be many sources of start commands, for example, when the driver starts the vehicle, the start command is automatically sent; when the vehicle is driving on a high-speed photovoltaic highway, the start command is sent when the vehicle speeding reminder system is manually activated.

[0078] The lane judging module 120 is configured to obtain the number of lanes and the lane where the vehicle is located according to the above image.

[0079] For the road image returned by the road information col...

Abstract

The invention discloses a vehicle overspeed warning method and system. On a photovoltaic expressway, the method comprises the following steps: acquiring an image of a road in front of vehicles; acquiring a quantity of the lanes and lanes on which the vehicles are positioned according to the image; acquiring vehicle model information of the vehicles; obtaining speed limit values of the vehicles according to the quantity of the lanes, the lanes on which the vehicles are positioned, the vehicle model information of the vehicles and a mapping relation in a pre-stored expressway information table;measuring real-time speeds of the vehicles; judging whether the real-time speeds of the vehicles are higher than the speed limit values or not; if so, transmitting overspeed warning. According to thevehicle overspeed warning method and system provided by the invention, on the photovoltaic expressway, the quantity of the lanes and the lanes on which the vehicles are positioned are obtained by analyzing the image of the road in front of the vehicles, the speed limit values can be dynamically adjusted according to the current lanes on which the vehicles are positioned, and accurate speed limit information can be acquired.

Description

technical field [0001] The invention belongs to the field of automobile safety driving assistance, and in particular relates to a vehicle speeding reminder method and system. Background technique [0002] Photovoltaic highways lay photovoltaic panels to convert solar energy into electrical energy to power themselves. The electrical energy obtained by this power supply method is affected by the intensity of light. For a photovoltaic panel in a fixed area, when there is no vehicle passing by, the light intensity on it is stable, and the electrical signal it acquires is also stable. When a vehicle passes by, the light intensity on it gradually weakens to The minimum value is then gradually increased to a stable value. Similarly, the electrical signal it acquires also undergoes a process of gradually weakening to a minimum value and then gradually increasing to a stable value. Therefore, the change of the electrical signal acquired by the photovoltaic panel can be obtained by m...
