Detailed Description
Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.
The control strategy of the existing vehicle power system is mainly developed according to project experience of engineers, and all vehicles in the same project adopt a unified control strategy. Therefore, if there is a large difference in the driving habits of the users and the driving environments of the vehicles, the vehicles may not meet the actual demands of the users. In view of this, the inventors contemplate that the vehicle networking cloud platform may be utilized to analyze the driving habits of the user according to statistics of historical data of vehicle state information and synchronize to the vehicle, and the vehicle adaptively adjusts its own control strategy. In this way, a customized vehicle control strategy can be provided for the user, and the requirements of the user can be precisely met.
Fig. 1 is a schematic diagram of a scenario of a vehicle control method provided by an exemplary embodiment. As shown in fig. 1, communication between the vehicle 10 and the server 20 may be via associated wireless communication techniques. Wherein the vehicle 10 may communicate with the server 20 through a T-BOX loaded thereon. The server 20 is a cloud platform of the internet of vehicles. The controllers of the vehicle CAN communicate through a CAN message, the server CAN convert data uploaded by the vehicle from the CAN message into a form which CAN be operated by the server, and the data CAN be converted into CAN message data and then sent to the vehicle.
FIG. 2 is a flowchart of a vehicle control method provided by an exemplary embodiment, which is applied to the vehicle 10. As shown in fig. 2, the vehicle control method may include the following steps.
Step S21, status information of the vehicle is acquired.
Step S22, the state information is sent to the server, so that the server determines statistical data of the state information according to historical data of the state information, and the state information comprises the increasing rate of the accelerator pedal opening.
Step S23, receiving the statistical data of the state information sent by the server.
Step S24, updating a control strategy of the vehicle according to the statistical data of the state information, wherein the control strategy comprises the corresponding relation between the vehicle speed and the accelerator pedal opening under the same downshift point.
Wherein the status information may be a value of a parameter characterizing the status of the vehicle. For example, vehicle speed, daily on-vehicle time, daily charge time, charge mode (fast charge and slow charge), drive mode, number of braking per unit mileage, and the like. The status information may be obtained from various controllers in the vehicle or may be obtained directly from various dedicated sensors in the vehicle.
The vehicle may continuously transmit the status information to the server such that the server receives the status information corresponding to the plurality of time points, thereby forming history data of the status information. Specifically, the vehicle may be configured to periodically transmit the status information. The server may use data within a predetermined time period before the current time as history data, and determine the statistical data every predetermined time period. For example, the server determines statistical data of the vehicle speed according to all vehicle speeds received in the month at a fixed time at the end of each month, and sends the statistical data to the vehicle.
If the communication between the vehicle and the server is interrupted, the vehicle can store the vehicle state information first, and the vehicle is packaged and uploaded to the server integrally after being reconnected.
The server may determine an average or weighted average of the historical data of the state information as the statistical data of the state information. The weight may be related to a time when the state information is received, and the closer the receiving time is to the current time, the greater the weight of the corresponding state information.
The opening degree may be zero when the accelerator pedal is not depressed. When the accelerator pedal is depressed, the opening degree gradually increases. The rate at which the accelerator opening increases is the opening at which the accelerator pedal is depressed per unit time. The speed represents the urgent need of the driver to accelerate, and the larger speed indicates that the driver wants the vehicle to respond more quickly, the dynamics is emphasized, and the smaller speed indicates that the driver is emphasized on the driving stability and the fuel saving, and the economy is emphasized.
A downshift point refers to a specific downshift from one gear to the next. For example, a downshift from 2 to 1 is one downshift point, and a downshift from 3 to 2 is another downshift point. The same downshift point means a downshift from the same gear. In the related art, the vehicle control strategy is pre-stored with a MAP format, which is related to the correspondence relationship among the downshift point, the vehicle speed and the accelerator opening. For example, in a rectangular coordinate system, the abscissa is the vehicle speed, the ordinate is the accelerator pedal opening, and one downshift point corresponds to one curve in the coordinate system. One point in the curve corresponds to one vehicle speed and to one accelerator pedal opening. When the actual vehicle speed reaches the corresponding vehicle speed and the actual accelerator pedal opening reaches the corresponding accelerator pedal opening, the transmission is controlled to execute the downshift of the downshift point.
In the related art, the correspondence between the vehicle speed and the accelerator pedal opening is fixed at the same downshift point. In the scheme, under the same downshift point, the corresponding relation between the vehicle speed and the accelerator pedal opening can be adjusted according to the statistical data.
Through the technical scheme, the personalized control strategy can be updated for the user, and the requirements of the user can be accurately met. Specifically, the server obtains statistical data from historical data of a rate at which an accelerator opening of the vehicle increases, and the vehicle updates a correspondence between a vehicle speed and the accelerator opening at the same downshift point based on the statistical data. Because the historical data reflects the driving habit of the user, after the corresponding relation is updated according to the statistical data, the gear shifting control strategy of the vehicle can be more close to the driving habit of the user, and the user can drive the vehicle more efficiently.
In still another embodiment, the step of updating the control strategy of the vehicle according to the statistical data of the state information (step S24) may include:
determining a rate interval to which the statistical data belong; and searching the control strategy corresponding to the rate interval to which the statistical data belong in the corresponding relation between the preset control strategy and the rate interval. In the control strategy corresponding to the larger speed interval, the same vehicle speed corresponds to a smaller accelerator pedal opening under the same downshift point; and updating the current control strategy into the searched control strategy.
The rate at which the accelerator opening is increased may be divided into a plurality of rate intervals in advance, and the correspondence relationship between the control strategy and the rate intervals may be prestored. I.e. one rate interval corresponds to one control strategy. After the statistical data is determined, the rate interval to which the statistical data belongs is further determined, and then the corresponding control strategy is determined according to the rate interval to which the statistical data belongs.
As described above, the rate at which the accelerator opening degree increases represents the urgency of the driver's desire to accelerate, and the greater the rate, the greater the urgency. If the rate interval to which the statistical data belongs is a larger rate interval, it indicates that the driving habit of the driver is relatively strong, and it is desired to obtain stronger power faster and to respond faster. Therefore, in the control strategy corresponding to the larger speed section, the same vehicle speed corresponds to the smaller accelerator pedal opening at the same downshift point. Thus, the downshift can be realized earlier, and the driving habit of the driver is more met. Similarly, more oil consumption is needed for some road surfaces, so that drivers often adopt larger accelerator pedal opening increasing rates.
For example, fig. 3 is a graph of a shift point provided by an exemplary embodiment. As shown in fig. 3, the abscissa indicates the vehicle speed, the ordinate indicates the accelerator pedal opening, and the curve a is the curve of one of the downshift points. At a certain vehicle speed, when the accelerator pedal is depressed, the accelerator pedal opening increases, and in this coordinate system, a point determined by both the vehicle speed and the accelerator pedal opening moves upward as indicated by an arrow in fig. 3 until reaching a curve a, and a downshift is automatically performed. In this embodiment, the updated curve of the same downshift point is shown as curve B. If curve B is used, then at the same vehicle speed, a smaller accelerator opening is required to automatically downshift so that the vehicle responds to more power faster than in curve a. Curve B corresponds to a larger rate interval than curve a.
Fig. 3 shows only an exemplary change before and after updating of a curve (a downshift point). In each control strategy, a plurality of downshift points may be included, and updating the control strategy each time may include updating a curve of the plurality of downshift points, i.e., each control strategy includes a curve of the plurality of downshift points.
In yet another embodiment, only the curves in one downshift point may also be included in each control strategy. In this embodiment, the step of updating the control strategy of the vehicle according to the statistical data of the state information (step S24) may include:
determining a rate interval to which the statistical data belong; determining a downshift point corresponding to the statistical data; searching a control strategy corresponding to a speed interval to which the statistical data belongs and a downshift point corresponding to the statistical data in a corresponding relation among a preset control strategy, the downshift point and the speed interval, wherein under the same downshift point, the same vehicle speed corresponds to a smaller accelerator pedal opening in the control strategy corresponding to a larger speed interval; and updating the current control strategy into the searched control strategy.
Unlike the previous embodiment, in this embodiment, in addition to determining the rate interval to which the data belongs, a downshift point corresponding to the statistical data needs to be determined. And in one control strategy, only one downshift point curve is included. Alternatively, each downshift point correspondingly includes a plurality of control strategies. In the implementation process, the server can respectively determine the statistical data under each downshift point, and respectively update the control strategy under each downshift point.
In this embodiment, the user-personalized parameter adjustment can be performed for a single downshift point, so that the personalized setting is more refined.
In yet another embodiment, the status information may further include a charge start time of the vehicle, and the control strategy may further include a time to heat the power battery prior to charging the vehicle.
The charge start time may be a daily charge start time. If the statistical data is a daily charge start time, the vehicle may be controlled to heat the power battery at a predetermined time period before the daily charge start time. For example, the daily charge start time is 8 pm, then 7 pm 50 may be set to start heating the power battery (in the case of a vehicle that allows heating). Thus, the condition that the charging time is delayed due to the fact that the temperature of the power battery is too low is avoided.
Fig. 4 is a flowchart of a vehicle control method provided in an exemplary embodiment, which is applied to a server. As shown in fig. 4, the method may include the steps of:
step S41, receiving vehicle status information transmitted by the vehicle.
Step S42, determining statistical data of state information according to the historical data of the state information, wherein the state information comprises the increasing rate of the accelerator pedal opening.
Step S43, the statistical data of the state information is sent to the vehicle, so that the vehicle updates the control strategy of the vehicle according to the statistical data of the state information, and the control strategy comprises the corresponding relation between the vehicle speed and the accelerator pedal opening under the same downshift point.
The embodiment of the method applied to the server corresponds to the embodiment of the method applied to the vehicle in fig. 2, and will not be described herein.
Through the technical scheme, the server obtains statistical data according to the historical data of the increasing speed of the accelerator pedal opening of the vehicle, and the vehicle updates the corresponding relation between the vehicle speed and the accelerator pedal opening under the same downshift point according to the statistical data. Because the historical data reflects the driving habit of the user, after the corresponding relation is updated according to the statistical data, the gear shifting control strategy of the vehicle can be more close to the driving habit of the user, and the user can drive the vehicle more efficiently.
In still another embodiment, the step of determining statistical data of the state information according to the history data of the state information (step S42) may include, on the basis of fig. 4: an average or weighted average of the historical data of the status information is determined as statistical data of the status information.
The weight may be related to a time when the state information is received, and the closer the receiving time is to the current time, the greater the weight of the corresponding state information. In the embodiment, the statistical data calculation method is simple, the data processing speed is high, and errors are not easy to occur.
