As shown in Figure 1, Fig. 1 is a kind of limiting vehicle speed method flow diagram of the disclosure according to an exemplary embodiment, and the method may be used in various vehicle, such as: Electric Scooter, and two-wheeled balance car etc.
The method comprises the following steps:
In step 110, weather state information is detected by sensor.
In disclosure embodiment, the weather state information that can detect has a lot, such as: current temperature, current humidity and current visibility etc.Further, sensor can be used when detecting weather state information, such as: serviceability temperature sensor can detect current temperature etc.
In a disclosed embodiment, this weather state information can comprise at least one in current temperature, current humidity and current visibility.
In another disclosed embodiment, when detecting weather state information by sensor, at least one in following detection mode can be adopted:
Mode one: detect current temperature by temperature sensor.
Mode two: detect current humidity by humidity sensor.
Mode three: detect current visibility by visibility sensor.
In the step 120, judge whether current weather is inclement weather according to weather state information.
In disclosure embodiment, inclement weather can refer to hot weather, microthermal climate, sleety weather, foggy weather etc.In inclement weather, need to carry out speed limit to vehicle.
In step 130, if determine that current weather is inclement weather, calculate the speed limit of vehicle.
In disclosure embodiment, the speed limit of vehicle can calculate according to the speed limit set in advance for inclement weather, also can be calculate according to the maximum travelling speed of this vehicle.
In a disclosed embodiment, when calculating the speed limit of vehicle according to the speed limit preset for inclement weather, the speed limit preset of vehicle can be obtained in the following ways:
Mode one: if current temperature is greater than default high temperature threshold value, or when current temperature is less than default low temperature threshold, determines that current weather is inclement weather, obtains the temperature speed limit preset of vehicle.
In disclosure embodiment, if current temperature is greater than default high temperature threshold value, then show that current weather is hot weather.If current temperature is less than default low temperature threshold, then show that current weather is microthermal climate.
Such as: current temperature is 42 degree, default high temperature threshold value is 40 degree, then current temperature is greater than default high temperature threshold value, needing the vehicle to travelling to carry out speed limit, preventing the traffic hazard caused due to high temperature.
Again such as: current temperature is subzero 10 degree, and default low temperature threshold is 0 degree, then current temperature is greater than default low temperature threshold, needing the vehicle to travelling to carry out speed limit, preventing the traffic hazard caused due to low temperature.
Mode two: if when current humidity is greater than default humidity threshold, determines that current weather is inclement weather, obtains the humidity speed limit that vehicle is preset.
In disclosure embodiment, if when current humidity is greater than default humidity threshold, then showing that current weather humidity ratio is comparatively large, may be rainy day or snowy day, needing the vehicle to travelling to carry out speed limit, preventing the traffic hazard caused due to sleet.
Mode three: if when current visibility is less than default threshold of visibility, determines that current weather is inclement weather, obtains the visibility speed limit that vehicle is preset.
In disclosure embodiment, if when current visibility is less than default threshold of visibility, then show that the visibility of current weather is very low, may also large greasy weather or sandstorm sky, needing the vehicle to travelling to carry out speed limit, preventing the traffic hazard caused due to low visibility.
Said temperature speed limit is the speed limit for temperature; Humidity speed limit is the speed limit for humidity; Visibility speed limit is the speed limit for visibility.Wherein, temperature speed limit, humidity speed limit, visibility speed limit can be identical numerical value, also can be different numerical value.
If temperature speed limit, humidity speed limit, visibility speed limit are identical numerical value, then regardless of which kind of inclement weather, the speed limit of the vehicle got is all a numerical value; If temperature speed limit, humidity speed limit, visibility speed limit are not identical numerical value, then when running into inclement weather, the speed limit getting vehicle is different numerical value.
In another disclosed embodiment, when getting after temperature speed limit and/or humidity speed limit that vehicle presets and/or visibility speed limit calculate the speed limit of vehicle, the temperature speed limit can preset according to the vehicle obtained and/or humidity speed limit and/or visibility speed limit calculate the speed limit of vehicle.
Wherein, if when the default speed limit obtained only includes one in default temperature speed limit, humidity speed limit and visibility speed limit, calculate the speed limit of vehicle according to the default speed limit obtained.
If when the default speed limit obtained comprises at least two in default temperature speed limit, humidity speed limit and visibility speed limit, from all default speed limit obtained, choose the minimum default speed limit of numerical value, and calculate the speed limit of vehicle according to the default speed limit that numerical value is minimum.
During the speed limit of above-mentioned calculating vehicle, the numerical relation between default speed limit and the speed limit of vehicle can be selected as the case may be.
Such as: the default speed limit of acquisition only has one, i.e. temperature speed limit, then the speed limit of vehicle can be calculated according to this temperature speed limit.Wherein, result of calculation can be that the speed limit of vehicle is identical with temperature speed limit, and namely the speed limit of vehicle is 100% of temperature speed limit.
Again such as: the default speed limit of acquisition is multiple, i.e. temperature speed limit, humidity speed limit and visibility speed limit, now, minimum speed limit can be chosen from temperature speed limit, humidity speed limit and visibility speed limit, and calculate the speed limit of vehicle according to this minimum speed limit.Wherein, result of calculation can be 3/4ths of minimum speed limit for the speed limit of vehicle.
In another disclosed embodiment, in order to ensure the safety that user drives a vehicle further, restricted driving threshold speed that can also be default to vehicle set one, so, determine the speed limit of the vehicle that the temperature speed limit that the restricted driving speed of vehicle not only will be considered to preset according to the vehicle obtained and/or humidity speed limit and/or visibility speed limit calculate, also will consider the restricted driving threshold speed preset, the speed limit of vehicle can not exceed this restricted driving threshold speed preset in principle.
So, after the speed limit of the temperature speed limit preset according to the vehicle obtained and/or humidity speed limit and/or visibility speed limit calculating vehicle, can also comprise:
Judge whether the speed limit of the vehicle of temperature speed limit and/or humidity speed limit and/or the calculating of visibility speed limit preset according to the vehicle obtained is greater than the default restricted driving threshold speed of vehicle.If be greater than default restricted driving threshold speed, then the restricted driving threshold speed preset using vehicle is as the speed limit of vehicle; If be not more than default restricted driving threshold speed, then still using the speed limit of the vehicle calculated according to the temperature speed limit preset of vehicle obtained and/or humidity speed limit and/or visibility speed limit as the speed limit of vehicle.
Such as: the speed limit calculated is 20 kilometers/hour, and the restricted driving threshold speed preset is 10 kilometers/hour, and now the speed limit of vehicle can be 10 kilometers/hour.
Again such as: the speed limit calculated is 20 kilometers/hour, and the restricted driving threshold speed preset is 30 kilometers/hour, and now the speed limit of vehicle can be 20 kilometers/hour.
In step 140, start speed limit driving mode, the speed limit according to vehicle carries out speed limit to vehicle.
In disclosure embodiment, vehicle can start speed limit driving mode, can control the speed limit of travel speed lower than vehicle of vehicle, thus ensures the traffic safety of user.
As seen from the above-described embodiment; vehicle can detect weather state information by the sensor being arranged on self; when being inclement weather according to weather state information determination current weather; calculate the speed limit of vehicle; and start speed limit driving mode; speed limit according to vehicle carries out speed limit to vehicle; make this vehicle automatically can control the travel speed of self according to weather conditions; especially during inclement weather; the travel speed of self can be limited; avoid the potential safety hazard caused due to inclement weather as far as possible, protect the driving safety of user better.
As shown in Figure 2, Fig. 2 is the another kind of limiting vehicle speed method flow diagram of the disclosure according to an exemplary embodiment, and the method may be used in various vehicle, and if execution step 130 in determine that current weather is inclement weather, when calculating the speed limit of vehicle, can comprise the following steps:
In step 210, be inclement weather according to weather state information determination current weather.

In a step 220, the speed limit of vehicle is calculated according to the maximum travelling speed of vehicle.
In disclosure embodiment, the speed limit of vehicle can be 3/4ths of the maximum travelling speed of vehicle.
Such as: two-wheeled balance car maximum travelling speed is 16 kilometers/hour, it is 12 kilometers/hour by calculating the speed limit of this two-wheeled balance car.
In order to ensure the safety that user drives a vehicle further, restricted driving threshold speed that can also be default to vehicle set one, so, determine that the restricted driving speed of vehicle not only will consider the maximum traveling speed of vehicle, also will consider the restricted driving threshold speed preset, the speed limit of vehicle can not exceed this restricted driving threshold speed preset in principle.
In step 230, judge whether the speed limit of the vehicle calculated is greater than the default restricted driving threshold speed of vehicle.When the speed limit of vehicle is greater than the restricted driving threshold speed that vehicle presets, perform step 240; When the speed limit of vehicle is not more than default restricted driving threshold speed, perform step 250.
In step 240, the restricted driving threshold speed preset using vehicle is as the speed limit of vehicle.
In step 250, still to calculate the speed limit of speed limit as vehicle of vehicle according to the maximum travelling speed of vehicle.
As seen from the above-described embodiment, vehicle according to the speed limit determining vehicle according to maximum travelling speed and default restricted driving threshold speed of self, thus can improve the efficiency of the speed limit obtaining vehicle.

In step 320, judge whether current weather is inclement weather according to weather state information.
In a step 330, if determine that current weather is inclement weather, calculate the speed limit of vehicle.
In step 340, start speed limit driving mode, the speed limit according to vehicle carries out speed limit to vehicle.
In step 350, when not being inclement weather according to weather state information determination current weather, close speed limit driving mode, and remove the speed limit to vehicle.
In disclosure embodiment, if current temperature is not more than default high temperature threshold value, or when current temperature is not less than default low temperature threshold, then can close speed limit driving mode, and remove the speed limit to vehicle, recover normal travel speed.
If when current humidity is not more than default humidity threshold, then can close speed limit driving mode, and remove the speed limit to vehicle, recover normal travel speed.
If when current visibility is not less than default threshold of visibility, then can close speed limit driving mode, and remove the speed limit to vehicle, recover normal travel speed.
