The user can then input the vehicle surrounding environment information and input the user's driving ability information based on the vehicle travel information. The vehicle surrounding environment information and the driving ability information can be input in a mode that a user selects preset vehicle surrounding environment information options and driving ability options. For example, the corresponding preset weather option is preset: sunny, cloudy, light rain, medium rain, heavy rain, fog, snow; presetting road condition options: leveling, pothole, muddy and wading; road type option: urban roads, rural roads, mountain roads, highways; presetting a driving capability option: low, medium, high. Therefore, the user can select the options based on the vehicle running information to obtain the surrounding environment information and the driving capacity information of the vehicle.

In another embodiment, step S100 includes the steps of:
step S120, vehicle running information and driving ability information input by a user are obtained;
and step S121, obtaining the surrounding environment information of the vehicle according to the vehicle running information.
Specifically, a user obtains vehicle running information through a preset server, then analyzes the vehicle running information to obtain vehicle surrounding environment information, and obtains driving ability information input by the user, thereby obtaining the vehicle surrounding environment information and the driving ability information. In the embodiment, the user only needs to input the driving capacity information, and the vehicle running information such as the vehicle position, the weather, the road state, the current time period, the vehicle speed limit state and the like can be obtained through the preset server, so that the vehicle running information is analyzed to obtain the surrounding environment information of the vehicle, the information required to be input by the user is reduced, and the convenience of user operation is improved.
Step S200, generating a speed limit instruction according to the vehicle surrounding environment information and the driving capacity information;
specifically, a corresponding speed limit value may be generated according to the vehicle surrounding environment information and the driving capability information, and a corresponding speed limit instruction may be generated according to the speed limit value. For example, the highest speed limit value of the current driving road is obtained according to the vehicle surrounding environment information, then the corresponding speed limit parameter is obtained according to the road condition information, the weather information, the current time period information, the driving capability information and the like in the vehicle surrounding environment information, the recommended speed limit value is obtained according to the highest speed limit value and the speed limit parameter, and the corresponding speed limit instruction is generated according to the recommended speed limit value.
In another embodiment, step S200 further comprises the steps of:
step S210, generating a recommended speed-limiting interval according to the surrounding environment information and the driving capacity information, and outputting the recommended speed-limiting interval;
and step S220, acquiring a first speed limit value selected by the user based on the recommended speed limit interval, and generating a corresponding speed limit instruction according to the first speed limit value.
Specifically, a corresponding recommended speed-limit interval may be generated according to the surrounding environment information and the driving ability information, and the recommended speed-limit interval may be output in a form of voice or image, so that the user can know the recommended speed-limit interval. And then acquiring a first speed limit value selected by the user based on the recommended speed limit interval, and generating a corresponding speed limit instruction according to the first speed limit value. In the embodiment, the recommended speed limit interval is pushed to the user for selection, and then the speed limit instruction is generated according to the first speed limit value selected by the user, so that the flexibility of speed limit value selection is improved, and better user experience is brought.
Further, the vehicle surrounding environment information includes road type information, weather information, and road condition information, and the step S210 further includes the steps of:
step S211, obtaining a corresponding preset speed interval according to the road type information;
step S212, obtaining a corresponding preset speed limit coefficient according to the weather information, the road condition information and the driving capacity information;
and step S213, obtaining a corresponding recommended speed limit interval according to the preset speed interval and the preset speed limit coefficient.
Specifically, the environmental information around the vehicle includes road type information, weather information, and road condition information, and corresponding speed sections may be preset according to different road types, for example, a preset speed section corresponding to an urban road is 30-60 km/h, a preset speed section corresponding to a rural road is 60-80 km/h, a preset speed section corresponding to a mountain road is 30-50 km/h, and a preset speed section corresponding to an expressway is 80-120 km/h. And then road information or vehicle position information acquired by a sensor of the vehicle is obtained through a preset sensor, and further road type information is determined. Meanwhile, corresponding speed limit coefficients can be preset according to different weather, different vehicle conditions and different driving capabilities, for example, a weather coefficient T is preset: fine T ═ 1, light rain T ═ 0.95, medium rain T ═ 0.9, heavy rain T ═ 0.8, fog T ═ 0.7, snow T ═ 0.6; presetting a road condition coefficient K, wherein the flat road surface K is equal to 1, the hollow road surface K is equal to 0.9, the muddy road surface K is equal to 0.8, and the wading road surface K is equal to 0.7; preset drivability coefficient J: high J is 1, medium J is 0.9, low J is 0.8. And then, acquiring a corresponding preset speed interval according to the road type information, and acquiring a corresponding preset speed limit coefficient according to the weather information, the road condition information and the driving capacity information. And further obtaining a corresponding recommended speed limit interval according to the following formula:
Vout＝Vin×T×K×J
wherein, VoutFor recommending the end point value V of the speed limit intervalinThe speed range is a preset speed range endpoint value, T is a preset weather coefficient, K is a preset road condition coefficient, and J is a preset driving capacity coefficient. And respectively calculating two endpoint values of the recommended speed-limiting interval to further obtain the recommended speed-limiting interval. Assuming that the road type information is an urban road, the preset speed interval is 30-60 km/h; if the weather information is clear, the preset weather coefficient T is 1, and if the road condition information is a pothole road surface, the preset road condition coefficient K is 0.9; if the driving capability information is medium, the preset driving capability coefficient J is 0.9, and then the recommended speed limit sections (30 × 1 × 0.9) to (60 × 1 × 0.9), that is, 24.3 to 48.6km/h, can be obtained according to the speed section and the speed limit coefficient. It is understood that the preset speed limit coefficient may include a preset speed limit coefficientThe weather coefficient, the preset road condition coefficient, the preset driving ability coefficient, and other speed limiting coefficients such as a preset time period coefficient (i.e., divided according to the time period in which the vehicle is traveling, for example, a day time coefficient of 1, early morning and evening coefficients of 0.9, and a night time coefficient of 0.8) may also be included. Those skilled in the art can understand that, in this embodiment, implementation equipment for the calculation process of the recommended speed limit interval is not limited, and may be a terminal held by a user, a preset server (a big data platform), and similarly, a vehicle end.
And step S300, sending the speed limit instruction to a vehicle end through a preset server so that the vehicle end controls the speed of the vehicle according to the speed limit instruction.
Specifically, after a speed limit instruction is generated, the speed limit instruction may be issued to a vehicle-mounted terminal of the vehicle end through a preset server, after the vehicle-mounted terminal receives the speed limit instruction, a speed limit signal is sent to a vehicle control unit through a Controller Area Network (CAN) Network, and finally the vehicle control unit limits the speed of the vehicle according to the speed limit signal, so that the vehicle end controls the speed limit of the vehicle according to the speed limit instruction.
In the first embodiment of the present invention, the information input by the user or the information of the surrounding environment of the vehicle (such as weather information, road condition information, road type information, current geographical position of the vehicle, battery level, current speed limit state of the vehicle, etc.) and the driving capability information may be obtained through the preset server. And then generating a corresponding speed limit value according to the surrounding environment information and the driving capability information of the vehicle, and generating a corresponding speed limit instruction according to the speed limit value. And finally, the speed limit instruction can be issued to a vehicle-mounted terminal of the vehicle end through a preset server, so that the vehicle end controls the speed limit of the vehicle according to the speed limit instruction, and the speed limit operation of the vehicle is completed. In the implementation, a user acquires the surrounding environment information and the driving capacity information of the vehicle through the terminal equipment, and generates a speed limit instruction based on the surrounding environment information and the driving capacity information of the vehicle to control the speed limit of the vehicle, so that the active adjustment of the speed limit of the vehicle is realized, and the intellectualization of the speed limit of the vehicle is improved.
Further, referring to fig. 2, a second embodiment of the invention provides a method for limiting speed of a vehicle, based on the above embodiment shown in fig. 1, the step S100 includes the following steps:
step S130, vehicle authentication information of a user is obtained, and whether the user has a speed limit permission or not is judged according to the vehicle authentication information;
step S131, if the speed limit authority exists, executing step S100;
and step S132, if the speed limit authority is not provided, the speed limit operation is not executed.
Specifically, the user needs to authenticate the ownership of the vehicle before performing the speed limiting operation, for example, the user obtains the vehicle authentication information by authenticating the purchase information, the driving license and other related vehicle ownership information of the user. According to the vehicle authentication information, if the user passes the authentication of the vehicle ownership, indicating that the user is the owner of the vehicle and has the vehicle ownership, then step S100 is executed. And if the authentication of the vehicle ownership is not passed, the user is not the owner of the vehicle and does not have the vehicle ownership, and the speed-limiting operation of the user is not executed. In the embodiment, the vehicle authentication information is verified before the vehicle speed limit is executed, so that the speed limit operation is ensured to be performed by a vehicle owner with the vehicle ownership, the illegal operation of a user who is not the vehicle owner is avoided, and the safety of the vehicle speed limit operation is improved.
Further, referring to fig. 3, a third embodiment of the invention provides a method for limiting speed of a vehicle, based on the above embodiment shown in fig. 1, before step S300, the method further includes the following steps:
and step S310, acquiring a second speed limit value input by a user, and generating a corresponding speed limit instruction according to the second speed limit value.
Specifically, the second speed limit value is a user-defined speed limit value. And the user can directly input the self-defined second speed limit value, and then a corresponding speed limit instruction can be generated according to the second speed limit value. And then the speed limit instruction is sent to the vehicle end through a preset server, so that the vehicle end controls the vehicle to limit the speed to a second speed limit value according to the speed limit instruction. For example, when a user inputs a custom speed limit value of 60km/h, a corresponding speed limit instruction is generated according to the custom speed limit value and is sent to a vehicle end. And after the vehicle end receives the speed limit instruction, limiting the maximum speed per hour of the vehicle to be below 60 km/h. In the embodiment, the user can directly input any self-defined speed limit value to limit the speed of the vehicle in the self-defined speed limit value, so that the selectable range of the speed limit value selected by the user is enlarged on one hand, and the convenience of limiting the speed of the vehicle is improved on the other hand.
