Based on the hardware structure of the vehicle electric quantity early warning device but not limited to the hardware structure, the application provides a first embodiment of a vehicle electric quantity early warning method. Referring to fig. 2, fig. 2 shows a schematic flow chart of a first embodiment of a method for applying for vehicle electric quantity early warning.
It should be noted that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in an order different from that shown or described herein.
In this embodiment, the vehicle electric quantity early warning method includes:
s10, acquiring current driving data and historical charging data of a vehicle; the current driving data comprise initial electric quantity and estimated driving time corresponding to a current driving route, and time information and electric power consumption information of at least part of driven road sections in the current driving route;
the execution main body of the vehicle electric quantity early warning method is a vehicle-mounted host, the vehicle-mounted host is a vehicle-mounted terminal which is installed on a vehicle driving platform and has multiple functions of ETC passing, 3G or more wireless communication, online navigation, road condition information, travel guide, shopping, entertainment audio and video and the like, and the vehicle-mounted host can realize information communication between people and a vehicle and between the vehicle and the outside (the vehicle and the vehicle) in function. For example, before the user starts driving, the user may input a departure point and a destination for the current driving in the on-board host, and the on-board host plans and displays a driving route and an estimated driving time for the user according to the received departure point and destination.
In an embodiment of the present application, the current driving data may be a current driving route on which the user drives the vehicle, an initial amount of power before starting driving, an estimated driving time on which the currently driven vehicle drives, and time information and power consumption information of at least a part of driven road segments in the current driving route. The current driving route may be an optimal driving route planned for the user by the vehicle-mounted host after the user inputs the departure place and the destination, or a route which is saved by the vehicle-mounted host and is frequently driven by the user. The estimated running time length can be the running time length predicted by the vehicle-mounted host according to the running time lengths of other users on the current running route, or can also be obtained according to the running time length spent by the users for driving the vehicle on the current running route.
The time duration information may be a time duration consumed after the user drives the vehicle for a certain distance along the current driving route. If the current driving route totals 30km, the user drives the automobile at the current moment and has driven for 20km, and the time is 30 minutes. The power consumption information refers to the power consumed by the user for driving the vehicle to travel a certain distance along the current travel route, for example, the total of 30km of the current travel route, the user drives the vehicle to travel for 20km at the current moment, and the power consumption is 38%.
The historical charging data includes, but is not limited to, the charging times, the charging duration, the charging remaining capacity, the charging mode and other data of the user in the historical preset time period. The historical preset time period may be within seven days or within thirty days before driving, which is not limited in this embodiment. In one embodiment, the historical charging data is updated and collected after 12 hours a day in the morning.
If the user detects that the last charging information of the user is eight days before the user starts the driving, the historical charging data of the user within 30 days before the driving starts can be acquired. When the user inputs the home and the destination to the company, the vehicle-mounted host may re-plan the current driving route for the user, or may be the user's regular driving route recorded by the vehicle-mounted host. According to the current driving route, the distance between the user and the company is 20km, the estimated driving time is 30 minutes, and the initial electric quantity of the vehicle is 50% before the user starts driving. After the user drives for 4km in 7 minutes, the current electric quantity of the vehicle is 41%, the time length information of at least part of the road section driven by the user in the current driving route is 7 minutes, and the electric consumption information is 9%.
Step S20, obtaining a current charging threshold value of the vehicle according to the historical charging data;
s30, obtaining the predicted residual electric quantity of the vehicle at a preset future time point according to the initial electric quantity, the electric power consumption information and the duration information;
step S40, judging whether the predicted residual capacity is smaller than the charging threshold value;
and S50, if the predicted residual electric quantity is smaller than the charging threshold, outputting charging reminding information.
Specifically, the current charging threshold may be a minimum charging value obtained from the historical charging data. The historical charging data can be updated in real time in a historical preset time period, namely the historical preset time period is automatically updated after 12 hours every morning, and then the current charging threshold value can be adjusted according to the driving habits of the user. For example, after the user a sells the vehicle to the user B, the current charging threshold value is obtained to be 20% lower according to the historical charging data of the user a, but the user B is used to charge the vehicle when the vehicle electric quantity is 40%. Therefore, the current charging threshold value can be adjusted in real time according to the driving habits of different users by updating the historical preset time period in real time, and the user experience is further improved. The predicting of the remaining power may be predicting a current power of the vehicle at a future time according to the time length information and the power consumption amount information of a part of the traveled route when the user drives the vehicle.
For example, a user drives a car to a company, and the current driving distance is 20km, the initial electric quantity is 40%, and the estimated driving time is 30 minutes, which can be obtained according to the current driving data. The user starts at the time of ten o 'clock, the current electric quantity of the vehicle is 31% after the vehicle runs for seven minutes, so that the power consumption of the vehicle is 9% every seven minutes when the user runs at the current speed, and the current charging threshold of the user is assumed to be 20%, the predicted residual electric quantity of the vehicle driven by the user at the time of twenty o' clock is 13%, and the user needs to run the current running route at the time of thirty o 'clock according to the predicted running time, so that the user is still in the state of driving the vehicle when the user runs at the time of twenty o' clock. Therefore, the predicted residual capacity of the vehicle measured at the point ten and twenty-one minutes is 13% and is less than the charging threshold value 20%, and at the moment, the vehicle-mounted host outputs charging reminding information to the user to remind the user of charging in time.
In the embodiment, the current running data and the historical charging data of the vehicle are acquired; the current driving data comprise initial electric quantity and estimated driving time corresponding to a current driving route, and time information and electric power consumption information of at least part of driven road sections in the current driving route; obtaining a current charging threshold value of the vehicle according to the historical charging data; obtaining the predicted residual electric quantity of the vehicle at a preset future time point according to the initial electric quantity, the power consumption information and the duration information; judging whether the predicted residual capacity is smaller than the charging threshold value; and if the predicted residual electric quantity is smaller than the charging threshold value, outputting charging reminding information. Therefore, the current charging threshold value of the vehicle is determined according to the charging habit of the user, the judgment of the charging threshold value can be more suitable for the vehicle using habit of the user, and the user experience is improved. Meanwhile, in the driving process of the user, the charging reminding information can be sent to the user in advance by judging whether the predicted residual capacity of the preset future time point is smaller than the current charging threshold value. Compare in current mode of showing the residual capacity, this application can send the warning in advance, and the fault-tolerant time of reserving for the user is longer, and then avoids the electric quantity of vehicle to be exhausted and leads to the dangerous situation that the vehicle is forced to park to take place.
Further, as an embodiment, referring to fig. 3, the application provides a second embodiment of a vehicle electric quantity early warning method, and referring to fig. 3, fig. 3 shows a flowchart of the second embodiment of the vehicle electric quantity early warning method.
In this embodiment, the step S30 includes:
step S301, dividing the preset running time into a plurality of preset time intervals to obtain a plurality of preset future time points;
step S302, obtaining the predicted power consumption of the vehicle in the preset time interval according to the power consumption information and the duration information;
and step S303, obtaining the predicted residual electric quantity of the vehicle at any preset future time point according to the initial electric quantity and the predicted electric consumption.
In a specific embodiment of the present application, the plurality of preset time intervals may be a plurality of time periods with equal time intervals. A specific moment is taken as an initial time point, and a plurality of preset future time points can be obtained after a plurality of preset future time intervals are added to the initial time point. The predicted power consumption amount refers to an amount of power consumed by a user driving a vehicle for a preset time interval.
For example, when a user drives an automobile to drive the automobile to a destination, the departure time is ten-point, the initial electric quantity is 50%, the estimated driving time is 30 minutes, the estimated driving time is divided into 5 preset time intervals, a preset time interval and a plurality of preset future time points are obtained, namely the preset time interval is 6 minutes, and the preset future time points are respectively: sixty-zero sixty minutes, twelve tenths, eighteen tenths, twenty-four tenths, and thirty-three tenths. After a user drives the vehicle to start running, the current electric quantity of the vehicle is measured to be 42% at a point of ten, and the predicted electric consumption amount of the vehicle is 8% according to the initial electric quantity of the point of ten and the current electric quantity of the point of ten, zero and six, so that the predicted residual electric quantity of the vehicle at a preset future time point is measured according to the initial electric consumption amount and the predicted electric consumption amount, namely the predicted residual electric quantity of the vehicle at the point of ten, twelve minutes is 34%, the predicted residual electric quantity at the point of ten, eighteen minutes is 26%, the predicted residual electric quantity at the point of ten, twenty-four minutes is 18%, and the predicted residual electric quantity at the point of ten, thirty minutes is 10%.
In this embodiment, the estimated travel time is divided into a plurality of preset time intervals to obtain a plurality of preset future time points, so that after a user starts driving, the first current electric quantity lower than the future time points can be obtained, the predicted electric consumption of the vehicle in the preset time intervals can be obtained by combining the initial electric quantity, and finally, the predicted residual electric quantity of any subsequent preset future time point is calculated according to the predicted electric consumption and the initial electric quantity, so that whether the predicted residual electric quantity is smaller than the current charging threshold value in the preset future time points of the vehicle can be obtained in advance. When the situation that the predicted residual electric quantity is smaller than the current charging threshold value in the preset future time point is judged, charging reminding information can be sent to the user in advance, and a long fault-tolerant time is reserved for the user, so that the user can reach a charging place before the electric quantity is exhausted, and the dangerous situation that the vehicle is forced to stop due to the fact that the electric quantity of the vehicle is exhausted is avoided.
Further, as an embodiment, referring to fig. 4, the present application provides a third embodiment of a vehicle electric quantity early warning method. Referring to fig. 4, fig. 4 is a flowchart illustrating a third embodiment of a vehicle charge amount warning method.
In this embodiment, before the step S10, the method further includes:
step S101, judging whether the current driving route is a preset driving route or not;
step S102, if the current driving route is a preset driving route, the steps of obtaining the initial electric quantity and the estimated driving time length corresponding to the current driving route, and the time length information and the electric power consumption information of at least part of the driven road sections in the current driving route are executed.
In the embodiment of the present application, the preset travel route may be a route that is frequently traveled and is saved in the in-vehicle host by the user. For example, when the user is a work user, the preset travel route may be a home-to-company or a company-to-home travel route; when the user is a teacher, the preset driving route can be a driving route from home to school or from school to home.
And if the current driving route of the user is not the preset driving route, monitoring the electric quantity of the vehicle in real time to obtain the real-time electric quantity of the vehicle, and when the real-time electric quantity of the vehicle approaches the current charging threshold value in the preset range, sending charging reminding information to the user to remind the user of charging in time. If the user is a user on duty, the user drives to the park for playing for the first time in the month, therefore, on the road where the user drives to the park, the vehicle-mounted host monitors the electric quantity of the vehicle in real time, when the real-time electric quantity at a certain moment is 35% and the current charging threshold is 25%, in order to ensure that the user does not have the condition of forced parking due to electric quantity exhaustion in the subsequent driving process, the user can send information to remind the user of charging when the real-time electric quantity is close to the current charging threshold within the preset range, namely the preset range is 10%. The preset range may be 10% or 15%, which is not limited in this embodiment.
In this embodiment, when the current driving route of the user is the preset driving route, the initial electric quantity and the estimated driving time corresponding to the current driving route, and the time length information and the electric power consumption information of at least part of the driven road sections in the current driving route are acquired, the predicted remaining electric quantity of the vehicle at the preset future time point is acquired according to the initial electric quantity, the electric power consumption information and the time length information, and when the predicted remaining electric quantity is smaller than the current charging threshold, the charging reminding information is sent to the user. When the current driving route of the user is not the preset driving route, the electric quantity of the vehicle is monitored in real time, and when the real-time electric quantity of the vehicle is close to the current charging threshold value in the preset range, charging reminding information is sent to the user.
Therefore, when the current driving route of the user is the preset driving route, when the predicted residual electric quantity is smaller than the current charging threshold value, the charging reminding information is sent; when the current driving route of the user is not the preset driving route, the electric quantity of the vehicle is monitored in real time, when the real-time electric quantity is close to the current charging threshold value in the preset range, the charging reminding information is also sent, and after the charging reminding information is sent, the nearest charging place is sent to the user. And if the user does not arrive at the nearest charging place before the electricity is exhausted, sending current electricity exhaustion information to the server so that the server provides mobile charging service for the user according to the current electricity exhaustion information. Therefore, the charging reminding information is sent to the user in advance, the user can be guaranteed to arrive at the charging place before the electric quantity is exhausted, and the dangerous condition that the vehicle is forced to stop due to the fact that the electric quantity of the vehicle is exhausted is avoided.
Further, as an embodiment, referring to fig. 5, the present application provides four embodiments of a vehicle charging warning method. Referring to fig. 5, fig. 5 is a flowchart illustrating a fourth embodiment of a vehicle charge warning method.
Step S20, adaptively changing into step S201, and obtaining the current charging threshold according to the charging pile slow charging ratio, the charging pile fast charging ratio, the charging gun slow charging ratio, the charging gun fast charging ratio and the high-frequency charging residual capacity.
In the embodiment of the application, the historical charging data comprises the ratio of the high-frequency charging residual capacity to the charging mode; the charging mode duty ratio comprises a charging pile slow charging duty ratio, a charging pile fast charging duty ratio, a charging gun slow charging duty ratio and a charging gun fast charging duty ratio. The high-frequency charging remaining capacity refers to charging remaining capacity in which the number of times of charging remaining capacity before charging of the vehicle is the largest within a historical preset time period. As obtained from the historical charging data 30 days before this driving, the number of times when the charging remaining amount is 20% is 5, the number of times when the charging remaining amount is 30% is 3, and the number of times when the charging remaining amount is 40% is 2, it can be determined that the high-frequency charging remaining amount is 20% within 30 days before this driving. The charge share ratio refers to a frequency of the number of times the vehicle uses the charge in a historical preset time period. If, in 30 days before this driving, the number of times that the user used to fill the electric pile fast is 5, the number of times that the electric pile filled slowly is 1, the number of times that the rifle that charges fast is 3, the number of times that the rifle that charges slowly fills is 1, therefore can obtain that the electric pile that fills fast fills accounts for 50%, the electric pile that fills slowly fills accounts for 10%, the rifle that charges fast accounts for 30%, the rifle that charges slowly accounts for 10%.
Specifically, the current charging threshold value is obtained according to the charging pile slow charging ratio, the charging pile fast charging ratio, the charging gun slow charging ratio, the charging gun fast charging ratio, the high-frequency charging remaining capacity and a formula one, wherein the formula one includes: p = Q R1+ Q R2+ Q R3+ Q R4, where P is a current charging threshold, Q is a high-frequency charging remaining power, R1 is a charging pile slow charging ratio, R2 is a charging pile fast charging ratio, R3 is a charger slow charging ratio, and R4 is a charging gun fast charging ratio.
In this embodiment, the current charging threshold of the vehicle is more accurate according to the ratio of the high-frequency charging remaining capacity to the charging mode in the historical preset time period, and the historical preset time period is automatically updated after 12 am every day, and can be adjusted according to the current driving habit of the user. For example, after the user a sells the vehicle to the user B, the current charging threshold value is obtained to be 20% lower according to the historical charging data of the user a, but the user B is used to charge the vehicle when the vehicle electric quantity is 40%. Therefore, the historical preset time period is updated in real time, the current charging threshold value of the vehicle is determined according to the charging habit of the user, the judgment of the charging threshold value can be more suitable for the vehicle using habit of the user, and the user experience is improved.
