Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
The control strategy of the conventional vehicle power system is mainly developed according to project experience of engineers, and all vehicles in the same project adopt a uniform control strategy. Therefore, if there is a large difference between the driving habits of the users and the driving environment of the vehicle, there is a possibility that the vehicle cannot meet the actual demands of the users. In view of the above, the inventor thinks that the internet-of-vehicles cloud platform can be used, the driving habits of the user are analyzed and synchronized to the vehicle according to the statistics of the historical data of the vehicle state information, and the vehicle adaptively adjusts the control strategy of the vehicle. In this way, customized vehicle control strategies can be provided for the user, accurately fitting the needs of the user.
FIG. 1 is a schematic view of a vehicle control method according to an exemplary embodiment. As shown in fig. 1, the vehicle 10 and the server 20 may communicate with each other through a related wireless communication technology. Wherein the vehicle 10 may communicate with the server 20 through the T-BOX loaded thereon. The server 20 is a cloud platform of a car networking. The controllers of the vehicle CAN communicate with each other in a CAN message mode, the server CAN convert data uploaded by the vehicle from the CAN message mode into a mode capable of being 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 applied to the vehicle 10 in accordance with an exemplary embodiment. As shown in fig. 2, the vehicle control method may include the following steps.
In step S21, the state information of the vehicle is acquired.
Step S22, sending the state information to the server, so that the server determines statistical data of the state information according to the historical data of the state information, wherein the state information comprises the speed rate of increasing the opening degree of the accelerator pedal.
In step S23, the statistical data of the status information transmitted by the server is received.
And 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 opening degree of the accelerator pedal under the same downshift point.
The state information may be, among other things, values of parameters that characterize the state of the vehicle. For example, vehicle speed, daily vehicle usage time, daily charge time, charge mode (fast and slow), driving mode, number of brakes per unit of mileage, etc. The status information may be obtained from various controllers in the vehicle or directly from various dedicated sensors of the vehicle.
The vehicle may continuously transmit the status information to the server such that the server receives the status information corresponding to a plurality of points in time, thereby forming a history of the status information. Specifically, the vehicle may be configured to periodically transmit the status information. The server may take 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 the statistical data of the vehicle speed according to all the vehicle speeds received in the month at the fixed time at the end of each month and 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 firstly, and the vehicle state information is packaged and uploaded to the server integrally after being reconnected.
The server may determine an average or a weighted average of the history data of the state information as the statistical data of the state information. The weight may be related to a time when the status information is received, and the closer the receiving time is to the current time, the greater the weight of the corresponding status information is.
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 per unit time at which the accelerator is depressed. The speed reflects the urgency that the driver wants to accelerate, if the speed is higher, the driver wants the vehicle to quickly respond to higher power and pays attention to the power, and if the speed is lower, the driver pays attention to the driving stability, saves fuel and pays attention to the economy.
A downshift point is a situation where a particular gear is lowered to the next gear. For example, a downshift from gear 2 to gear 1 is one downshift point, and a downshift from gear 3 to gear 2 is another downshift point. The same downshift point refers to a downshift from the same gear by one. In the related art, the vehicle control strategy pre-stores the corresponding relationship among the downshift point, the vehicle speed and the accelerator pedal opening, and may be in the form of a MAP. For example, in a rectangular coordinate system, the abscissa is the vehicle speed, the ordinate is the accelerator 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. And when the actual vehicle speed reaches the corresponding vehicle speed and the actual accelerator pedal opening reaches the corresponding accelerator pedal opening, controlling the transmission to execute the downshift of the downshift point.
In the related art, the correspondence between the vehicle speed and the accelerator opening is fixed at the same downshift point. In the scheme, the corresponding relation between the vehicle speed and the opening degree of the accelerator pedal can be adjusted according to statistical data under the same downshift point.
By the technical scheme, the personalized control strategy can be updated for the user, and the requirements of the user can be met accurately. Specifically, the server obtains statistical data from historical data of the rate at which the accelerator pedal opening of the vehicle increases, and the vehicle updates the correspondence between the vehicle speed and the accelerator pedal opening at the same downshift point according to the statistical data. Since the historical data reflects the driving habits of the user, after the corresponding relation is updated according to the statistical data, the gear shifting control strategy of the vehicle can be closer to the driving habits of the user, and therefore the user can drive the vehicle more efficiently.
In still another embodiment, on the basis of fig. 2, 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 belongs; and finding the control strategy corresponding to the rate interval to which the statistical data belongs in the corresponding relation between the preset control strategy and the rate interval. Wherein, in the control strategy corresponding to the larger speed interval, the same vehicle speed corresponds to the smaller accelerator pedal opening degree under the same downshift point; and updating the current control strategy into the searched control strategy.
The rate at which the accelerator opening degree increases 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 are determined, the speed interval to which the statistical data belong is further determined, and then the corresponding control strategy is determined according to the speed interval to which the statistical data belong.
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 stronger the urgency. If the speed interval to which the statistical data belongs is a larger speed interval, the driving habit of the driver is more violent, the driver wants to obtain stronger power more quickly, and the response speed is expected to be faster. Thus, a control strategy corresponding to a larger speed interval may be provided in which the same vehicle speed corresponds to a smaller accelerator opening at the same downshift point. Therefore, the gear shifting can be realized earlier, and the driving habit of the driver is more met. In a similar way, some roads need more oil consumption, so that the driver often adopts a larger accelerator pedal opening increasing rate, and the scheme can also make the updated control strategy more accord with the road condition of vehicle driving.
For example, FIG. 3 is a graph of a shift point provided by an exemplary embodiment. As shown in fig. 3, the abscissa is the vehicle speed, the ordinate is the accelerator opening, and the curve a is a curve of one of the downshift points. At a certain vehicle speed, when the accelerator pedal is depressed, the accelerator opening increases, and in this coordinate system, a point determined by both the vehicle speed and the accelerator 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 will automatically downshift to allow the vehicle to respond more quickly to a larger power than in curve a. Curve B corresponds to a larger rate interval than curve a.
The change before and after the update of one curve (one downshift point) is only depicted in fig. 3 by way of example. In each control strategy, a plurality of downshift points may be included, and updating the control strategy each time may include updating a curve for the plurality of downshift points, i.e. including a curve for the plurality of downshift points in each control strategy.
In yet another embodiment, curves in only 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 belongs; determining a gear-down point corresponding to the statistical data; searching control strategies corresponding to a rate interval to which the statistical data belong and a downshift point corresponding to the statistical data in the corresponding relation among a preset control strategy, the downshift point and the rate interval, wherein the same vehicle speed corresponds to a smaller accelerator pedal opening degree in the control strategies corresponding to a larger rate interval at the same downshift point; and updating the current control strategy into the searched control strategy.
Unlike the previous embodiment, in this embodiment, besides determining the associated rate interval, a downshift point corresponding to the statistical data needs to be determined. Whereas in one control strategy only one curve of downshift points is included. Alternatively, each downshift point may include a plurality of control strategies. In a specific implementation process, the server may determine the statistical data at each downshift point, and update the control strategy at each downshift point.
In this embodiment, the personalized parameter adjustment of the user can be performed for a single downshift point, so that the personalized setting is more detailed.
In yet another embodiment, the state 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 before the vehicle is charged.
The charge start time may be a daily charge start time. If the statistical data is the daily charge start time, the vehicle may be controlled to heat the power battery at a predetermined time before the daily charge start time. For example, if the daily charge start time is 8 pm, then it may be set that 7 pm 50 starts to heat the power battery (if the vehicle is allowed to heat). Therefore, the situation 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 flow chart of a vehicle control method applied to a server according to an exemplary embodiment. As shown in fig. 4, the method may include the steps of:
in step S41, the vehicle status information transmitted by the vehicle is received.
In step S42, statistical data of the state information including the rate at which the accelerator opening increases is determined based on the history of the state information.
And step S43, sending the statistical data of the state information to the vehicle so that the vehicle updates the 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 opening degree of the accelerator pedal 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 is not described herein again.
According to the technical scheme, the server obtains statistical data according to historical data of the speed of increasing the opening degree of the accelerator pedal of the vehicle, and the vehicle updates the corresponding relation between the vehicle speed and the opening degree of the accelerator pedal at the same downshift point according to the statistical data. Since the historical data reflects the driving habits of the user, after the corresponding relation is updated according to the statistical data, the gear shifting control strategy of the vehicle can be closer to the driving habits of the user, and therefore the user can drive the vehicle more efficiently.
In yet another embodiment, on the basis of fig. 4, the step of determining statistical data of the state information from the historical data of the state information (step S42) may include: 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 status information is received, and the closer the receiving time is to the current time, the greater the weight of the corresponding status information is. In the embodiment, the statistical data calculation method is simple, the data processing speed is high, and errors are not easy to occur.
