[0025] The exemplary embodiments will be described in detail hereinafter with reference to the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0026] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0027] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, while others may be combined or partially combined. Therefore, the actual execution order may vary depending on the actual situation.

[0028] In this application, "plurality" refers to two or more. "And / or" describes the relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0029] The related technology directly obtains a preset driving style index based on the driver's profile. However, other influencing factors may make the matched preset driving style index unsuitable for the driver in the current scene. For example, the weather factors, the driver's mental state factors, road conditions factors, etc. in the current scene will have a significant impact on the determination of the driving style index, thereby reducing the adaptability of the driving style index.

[0030] To this end, one aspect of this application provides a method for adjusting the driving style index. Figure 1 , Figure 1 This is a flow chart of a method for adjusting a driving style index according to an exemplary embodiment of the present application. The adjustment method includes at least steps S110 to S120, which are described in detail as follows:

[0031] S110: Calculate the current cumulative duration ratio based on the current cumulative duration and the current statistical period; wherein the current cumulative duration is the cumulative duration during which the accelerator pedal opening of the vehicle is greater than or equal to a preset opening during the current statistical period.

[0032] The accelerator pedal refers to the accelerator pedal of a fuel vehicle and the accelerator pedal of a new energy electric vehicle. The driver adjusts the output power of the vehicle by stepping on or releasing the accelerator pedal to achieve acceleration / deceleration of the vehicle. The preset opening is a preset high opening of the accelerator pedal, which is close to the maximum opening of the accelerator pedal. This application defines an accelerator pedal opening greater than or equal to the preset opening as "large throttle", which indicates that the driver has stepped on the accelerator pedal significantly, causing the accelerator pedal opening to be high (i.e., greater than or equal to the preset opening).

[0033] The current statistical period and the following next statistical period are statistical periods of the same preset duration, that is, the duration of each statistical period is the same. This embodiment records the cumulative duration of the vehicle's accelerator pedal opening greater than or equal to the preset opening in each statistical period, that is, the cumulative duration of "high throttle" in each statistical period, and thus calculates the cumulative duration ratio in each statistical period in combination with the statistical period. The following is an illustrative explanation of the calculation process of the current cumulative duration ratio: record the current cumulative duration of the accelerator pedal opening greater than or equal to the preset opening in the current statistical period; divide the current cumulative duration by the duration corresponding to the current statistical period to calculate the current cumulative duration ratio, that is, take the ratio of the current cumulative duration to the duration corresponding to the current statistical period as the current cumulative duration ratio, and so on. The cumulative duration ratio in the corresponding statistical period can be quickly calculated, that is, the cumulative duration ratio of "high throttle" in the corresponding statistical period.

[0034] S120: If the current cumulative time ratio is outside the current cumulative time ratio interval corresponding to the current driving style index, the current driving style index is adjusted until the next cumulative time ratio is within the adjusted cumulative time ratio interval; wherein, the next cumulative time is the cumulative time during which the accelerator pedal opening of the vehicle is greater than or equal to the preset opening within the next preset statistical period, the next cumulative time ratio is the ratio between the next cumulative time and the next statistical period, and the adjusted cumulative time ratio interval corresponds to the adjusted driving style index.

[0035] The current cumulative driving time percentage interval corresponds to a parameter of the current driving style index. In some embodiments, each driving style index corresponds to a cumulative driving time percentage interval. That is, knowing the corresponding driving style index allows the corresponding cumulative driving time percentage interval to be quickly determined. In other embodiments, the corresponding cumulative driving time percentage interval can be determined in real time based on parameters related to the corresponding driving style index.

[0036] This embodiment determines whether to adjust the current driving style index by judging whether the current cumulative time ratio falls within the current cumulative time ratio interval corresponding to the current driving style index; if the current cumulative time ratio falls within the current cumulative time ratio interval, it indicates that the current driving style index is suitable for the driver currently controlling the vehicle, and there is no need to adjust the current driving style index.

[0037] If the current cumulative time length ratio is outside the current cumulative time length ratio interval, it indicates that the current driving style index is not suitable for the driver currently driving the vehicle, and the current driving style index needs to be adjusted, and the adjusted cumulative time length ratio interval is determined according to the adjusted driving style index; the cumulative time length of the accelerator pedal opening degree greater than or equal to the preset opening degree in the next statistical period is recorded to calculate the next cumulative time length ratio; it is judged whether the next cumulative time length ratio belongs to the next cumulative time length ratio interval or not, to determine whether the adjusted driving style index needs to be adjusted again, and so on, until the next cumulative time length ratio is located in the adjusted cumulative time length ratio interval, so as to complete the adjustment of the driving style index, and accurately determine the driving style index suitable for the driver.

[0038] The adjustment of the current driving style index will be exemplarily illustrated as follows; the critical values of the current cumulative time length ratio interval are the minimum critical cumulative time length ratio and the maximum critical cumulative time length ratio, which are introduced in detail as follows:

[0039] If the current cumulative time length ratio is less than the minimum critical cumulative time length ratio, the adjacent driving style index less than the current driving style index is taken as the adjusted driving style index.

[0040] For example, the current driving style index is 4, the current cumulative time length ratio is 20%, and the minimum critical cumulative time length ratio is 30%. The current driving style index is adjusted from 4 to 3 (i.e. the adjacent driving style index less than the current driving style index). In this embodiment, the driving style index is proportional to the corresponding cumulative time length ratio, that is, the greater the driving style index, the greater the corresponding cumulative time length ratio. Down-regulating the driving style index is equivalent to down-regulating the cumulative time length ratio interval, so that the adjusted next cumulative time length ratio is located in the next cumulative time length ratio interval corresponding to the down-regulated driving style index.

[0041] If the current cumulative time length ratio is greater than the maximum critical cumulative time length ratio, the adjacent driving style index greater than the current driving style index is taken as the adjusted driving style index.

[0042] For example, the current driving style index is 4, the current cumulative time length ratio is 41%, and the maximum critical cumulative time length ratio is 40%. The current driving style index is adjusted from 4 to 5 (i.e. the adjacent driving style index greater than the current driving style index). Similarly, up-regulating the driving style index is equivalent to up-regulating the cumulative time length ratio interval, so that the adjusted next cumulative time length ratio is located in the next cumulative time length ratio interval corresponding to the up-regulated driving style index.

[0043] The embodiment relates to a method for adjusting a driving style index. The method comprises the following steps: determining a current cumulative time length of a driving state of a vehicle, wherein the driving state is greater than or equal to a preset opening degree (full throttle); determining a current driving style index of the driver according to the current cumulative time length; determining a current cumulative time length proportion of the current cumulative time length; determining whether to adjust the current driving style index according to a membership relationship between the current cumulative time length proportion and a current cumulative time length proportion interval corresponding to the current driving style index; and adjusting the current driving style index until a next cumulative time length proportion is located in an adjusted cumulative time length proportion interval, so as to obtain a driving style index that is accurately adapted to the driver, improve the adaptability of the driving style index, and improve the driving experience and the driving satisfaction of the driver.

[0044] In another example embodiment of the present application, how to determine the current cumulative time length proportion interval corresponding to the current driving style index is described in detail, please refer to Figure 2 , Figure 2 is based on Figure 1 Another flowchart of the adjustment method of the driving style index is shown in the example embodiment. The adjustment method is based on S110 to S120 as shown in Figure 1 , and further comprises S210 to S220, which are described in detail as follows:

[0045] S210: determining the current driving style index according to the historical driving parameters of the driver.

[0046] The historical driving parameters include but are not limited to historical vehicle speed, historical steering behavior, historical following distance, historical preferred gear and historical energy consumption parameters, etc. The historical driving parameters can reflect the historical driving habits and style of the driver, so as to determine the historical driving style index of the driver, which can be used as the initial driving style index when the driver drives the vehicle again. In this embodiment, the current driving style index can be understood as the historical driving style index of the driver, which can be directly used as the current driving style index when the driver drives the vehicle again.

[0047] In some embodiments, the driver will be authenticated before driving the vehicle, including but not limited to portrait authentication and / or voiceprint authentication, to determine the identity information of the driver, so as to obtain the historical driving parameters corresponding to the identity information, i.e. the parameters reflecting the historical driving habits and style of the driver.

[0048] For example, when the historical driving parameters include different types of historical driving parameters, each type of historical driving parameter is matched with a corresponding type of preset driving parameter to obtain the preset driving parameters that are successfully matched; and the preset driving style indexes corresponding to all the preset driving parameters that are successfully matched are averaged to determine the current driving style index.

[0049] For example, historical vehicle speeds are matched against multiple preset vehicle speeds, historical steering behaviors are matched against multiple preset steering behaviors, and so on, to obtain successfully matched preset driving parameters. It is worth noting that not all historical vehicle speeds can be matched to corresponding preset driving parameters. In this example, only successfully matched preset driving parameters are analyzed to determine the corresponding preset driving style index for each successfully matched preset driving parameter. The average of the preset driving style indices corresponding to all successfully matched preset driving parameters is then calculated and used as the current driving style index. In certain embodiments, to facilitate data analysis and processing, the driving style indices are all integers. Therefore, if the calculated average is not an integer, it is rounded to an integer to be used as the current driving style index.

[0050] S220: Determine a current cumulative duration ratio interval corresponding to the current driving style index based on the cumulative duration ratios of the multiple samples corresponding to the current driving style index.

[0051] The sample cumulative duration ratio is a parameter determined under ideal calibration scenarios. It is the ratio of the cumulative duration of time the accelerator pedal opening is greater than or equal to the preset opening, calculated within the same statistical period, to the statistical period itself.

[0052] Exemplarily, the cumulative time proportions of multiple samples include the minimum critical cumulative time proportion of the samples and the maximum critical cumulative time proportion of the samples; the minimum critical cumulative time proportions of all samples corresponding to the current driving style index are averaged to obtain the average minimum critical cumulative time proportion of the samples; the maximum critical cumulative time proportions of all samples corresponding to the current driving style index are averaged to obtain the average maximum critical cumulative time proportion of the samples; the average minimum critical cumulative time proportion of the samples and the average maximum critical cumulative time proportion of the samples are used as critical values ​​respectively to determine the current cumulative time proportion interval corresponding to the current driving style index.

[0053] In this example, there are two types of sample cumulative duration: the minimum critical cumulative duration percentage and the maximum critical cumulative duration percentage. The corresponding average values ​​for each type are calculated and used as the corresponding critical values: the minimum critical cumulative duration percentage and the maximum critical cumulative duration percentage for the current cumulative duration percentage interval. This determines the current cumulative duration percentage interval corresponding to the current driving style index.

[0054] In another exemplary embodiment of the present application, how to determine the current vehicle-related power parameters based on the current driving style index is described in detail. Figure 3 , Figure 3 is based on Figure 2Another flowchart of the adjustment method of the driving style index according to the exemplary embodiment is shown. The adjustment method further includes S310-S320; wherein the current driving style index corresponds to preset power parameters in different preset working conditions, which are described in detail as follows:

[0055] S310: match the current working condition with the preset working condition to determine the target preset working condition matched with the current working condition.

[0056] The current working condition represents the current vehicle working condition, which can be divided into different working conditions according to different working condition parameters. For example, high-speed working condition, low-speed working condition, etc. The parameters of the current working condition include the current running state parameters of the vehicle, including but not limited to vehicle speed, acceleration, motor / engine speed, load, slope, battery SOC (electric vehicle), etc. The preset working condition is a pre-calibrated and stored vehicle running state, and for the same reason, different preset working conditions can be obtained according to different preset working condition parameters. For example, preset high-speed working condition, preset low-speed working condition, etc. The target preset working condition is the preset working condition with the highest matching degree with the current working condition, which is used to guide the power control of the vehicle.

[0057] S320: take the preset power parameters in the target preset working condition as the current power parameters, so that the vehicle travels based on the current power parameters.

[0058] The preset power parameters in the target preset working condition involve driving, recovery and steering power parameters, including but not limited to motor / engine target torque, gearbox gear, energy recovery intensity, etc.

[0059] An exemplary embodiment is described as follows: the current vehicle speed (60 km / h), motor speed (3000 rpm), battery SOC (70%), and slope (0%) are obtained by sensors. Compare the current working condition parameters with the preset working condition parameters, calculate the matching degree (such as Euclidean distance or weighted score), and determine the target preset working condition with the highest matching degree with the current working condition. Take the preset power parameters in the target preset working condition as the current power parameters, and send the related current power parameters to the corresponding controller to control the vehicle to travel.

[0060] The application scenarios of the above-mentioned multiple adjustment methods are exemplarily described in another exemplary embodiment of the present application, which is described in detail in Figure 4 , Figure 4 is a schematic diagram of the application scenario of the adjustment method of the driving style index according to the present application.

[0061] The server 200 can be the execution subject of the adjustment method shown in any of the above exemplary embodiments to execute any of the above adjustment methods, which are exemplarily described as follows:
