Description

Technical Field

[0001] The present invention relates to the field of vehicle control technology, and in particular to an optimization method, device, equipment and storage medium for engine accelerator pedal characteristics. Background Art

[0002] The engine throttle pedal characteristic (PedalMap) is a curve showing the corresponding relationship between the engine output torque, the accelerator pedal opening, and the engine speed. The engine PedalMap is a core parameter in the engine drivability design and a key factor affecting the user's driving experience.

[0003] There are two main traditional methods for setting engine PedalMap: 1) setting one engine PedalMap, and all driving conditions use one set of parameters; 2) setting several engine PedalMaps, differentiated by driving mode (comfort mode, sport mode, economy mode, etc.), each driving mode corresponds to a set of engine PedalMaps, and users can manually select the driving mode and switch between several sets of engine PedalMaps through manual operation.

[0004] The main disadvantages of the above setting method are: the PedalMap parameters are fixed and unchanged, and the compatibility with the driving needs of special users is poor. Whether it is one or several sets of engine PedalMap, the parameters are fixed and cannot be changed. When these parameters are initially set, the driving habits of most users must be considered, and it is impossible to take into account a small number of users who have special needs for power. This setting method can meet the driving needs of most users, but it cannot meet the differentiated needs of a small number of special users, so it is urgently needed to be improved.

[0037] Embodiment 1

[0038] Figure 1A 1 is a flow chart of an engine accelerator pedal characteristics optimization method provided according to the first embodiment of the present invention. This embodiment is applicable to the situation of how to optimize the engine accelerator pedal characteristics. The method can be executed by an engine accelerator pedal characteristics optimization device, which can be implemented in the form of hardware and / or software and can be integrated into an electronic device that carries the engine accelerator pedal characteristics optimization function, such as a vehicle controller. Figure 1AAs shown, the method for optimizing the engine throttle pedal characteristics of this embodiment may include:

[0039] S110. When receiving an optimization request for the accelerator pedal characteristic associated with the target driving mode, determine the current adjustment step value of the adjustable parameter according to the maximum adjustment step value of the adjustable parameter of the accelerator pedal characteristic and the utilization rate of the standard range of the accelerator pedal opening in the optimization request.

[0040] In this embodiment, the optimization request is used to instruct the vehicle controller to optimize the adjustable parameters of the accelerator pedal characteristics, and is generated by the cloud when it monitors that the target vehicle has a dynamic demand under the target driving mode; optionally, the optimization request may include a standard range of accelerator pedal opening.

[0041] Among them, the standard range of accelerator pedal opening refers to the accelerator pedal opening range under the target driving mode adopted within the set duration during the use of the vehicle for all vehicles of the same vehicle as the target vehicle. For example, for all vehicle users of model A, the total time of using the target driving mode is 100 hours, among which the use time of the driving pedal opening range of 0-50% is 90 hours, then the accelerator pedal opening range corresponding to the target driving mode is set to 0-50%.

[0042] The so-called usage rate of the standard range of accelerator pedal opening refers to the usage rate of the standard range of accelerator pedal opening of the target vehicle during driving; optionally, the usage rate of the standard range of accelerator pedal opening of the target vehicle in the target driving mode can be determined based on a first usage time of the target vehicle using the target driving mode and a second usage time of the target vehicle using the standard range of accelerator pedal opening in the target driving mode.

[0043] The so-called accelerator pedal characteristic is the corresponding relationship curve between the engine output torque, the accelerator pedal opening, and the engine speed. It should be noted that in the vehicle controller, the accelerator pedal characteristic is expressed as follows: Figure 1B The table is shown in the form of a table; wherein the accelerator pedal opening and the engine speed correspond one to one, and a corresponding pair of accelerator pedal opening and engine speed corresponds to an engine output torque (engine torque). For example, when the accelerator pedal opening is 50% and the engine speed is 2000r / min, the corresponding engine torque is 130.9Nm. The so-called adjustable parameter is the engine torque corresponding to the accelerator pedal opening and the engine speed.

[0044] The so-called maximum adjustment step value refers to the maximum adjustable value of the adjustable parameter, that is, the maximum value that can be increased when the adjustable parameter is optimized once. For example, the default value of the adjustable parameter can be multiplied by the first set multiple and the result obtained is taken as the maximum adjustable value, where the first set multiple is less than 1, for example, it can be 0.1.

[0045] The so-called current adjustment step value refers to the adjustment step value used when adjusting the adjustable parameter currently.

[0046] Specifically, when the cloud detects that the target vehicle has the power demand under the target driving mode, it sends an optimization request for the accelerator pedal characteristics associated with the target driving mode to the target vehicle; accordingly, when the vehicle controller in the target vehicle receives the optimization request for the accelerator pedal characteristics associated with the target driving mode, it determines the current adjustment step value of the adjustable parameters based on the maximum adjustment step value of the adjustable parameters of the accelerator pedal characteristics and the usage rate of the standard range of the accelerator pedal opening in the optimization request.

[0047] In an optional manner, the vehicle controller may determine the current adjustment step value of the adjustable parameter based on certain rules, according to the maximum adjustment step value of the adjustable parameter of the accelerator pedal characteristic and the utilization rate of the standard range of the accelerator pedal opening in the optimization request.

[0048] For example, based on the correspondence between the adjustment step and the usage rate, a linear interpolation algorithm can be used to determine the intermediate adjustment step value according to the usage rate of the standard range of the accelerator pedal opening; if the intermediate adjustment step value is less than the maximum adjustment step value, the intermediate adjustment step value is used as the current adjustment step value for determining the adjustable parameter; if the intermediate number of step values ​​is equal to or greater than the maximum adjustment step value, the maximum adjustment step data is used as the current adjustment step value for determining the adjustable parameter.

[0049] Specifically, the correspondence between the adjustment step and the usage rate can be that the origin corresponds to: the usage rate is the standard range usage rate and the adjustment step is 0, and the end point corresponds to: the usage rate is 50% and the adjustment step is the maximum adjustment step value; then a linear interpolation algorithm is used to obtain an intermediate adjustment step value based on the usage rate within the standard range of the accelerator pedal opening; and then the current adjustment step value of the adjustable parameter is determined based on the intermediate adjustment step value and the maximum adjustment step value. For example, if the intermediate adjustment step value is less than the maximum adjustment step value, the intermediate adjustment step value is used as the current adjustment step value for determining the adjustable parameter; if the intermediate number of step values ​​is equal to or greater than the maximum adjustment step value, the maximum adjustment step data is used as the current adjustment step value for determining the adjustable parameter.

[0050] S120: Optimize the adjustable parameter according to the current adjustment step value, the current parameter value of the adjustable parameter, and the maximum boundary value.

[0051] In this embodiment, the current parameter value is the current value of the adjustable parameter. The so-called maximum boundary value is the maximum limit of the adjustable parameter, for example, it can be a second set multiple of the default value of the adjustable parameter, such as 1.5.

[0052] Specifically, the current adjustment step size, the current parameter value of the adjustable parameter and the maximum boundary value can be input into the parameter optimization model, and after being processed by the model, the optimized parameter value of the adjustable parameter is obtained, and the current parameter value is updated using the optimized parameter value.

[0053] It should be noted that during the first optimization, the current parameter values ​​of the adjustable parameters are the default parameter values, that is, the values ​​set when the vehicle leaves the factory.

[0054] It should also be noted that the optimization method for the engine torque (ie, the adjustable parameter) corresponding to each pair of accelerator pedal opening and engine speed is optimized in the manner described in the above steps.

[0055] In addition, it should be noted that the engine accelerator pedal characteristics optimization method for other driving modes is similar to the engine accelerator pedal characteristics optimization method for the target driving mode.

[0056] The technical solution of the embodiment of the present invention determines the current adjustment step value of the adjustable parameter according to the maximum adjustment step value of the adjustable parameter of the accelerator pedal characteristic and the utilization rate of the standard range of the accelerator pedal opening in the optimization request when receiving the optimization request for the accelerator pedal characteristic associated with the target driving mode, and then optimizes the adjustable parameter according to the current adjustment step value, the current parameter value of the adjustable parameter and the maximum boundary value. Through the above technical solution, the differentiation and intelligence of the engine throttle characteristic optimization are realized, thereby meeting the driving needs of users.

[0057] Embodiment 2

[0058] Figure 2 This is a flow chart of an optimization method for engine throttle pedal characteristics according to the second embodiment of the present invention. Based on the above embodiment, this embodiment further optimizes "optimizing the adjustable parameter according to the current adjustment step value, the current parameter value of the adjustable parameter and the maximum boundary value" to provide an optional implementation scheme. Figure 2 As shown, the method for optimizing the engine throttle pedal characteristics of this embodiment may include:

[0059] S210. When receiving an optimization request for the accelerator pedal characteristic associated with the target driving mode, determine the current adjustment step value of the adjustable parameter based on the maximum adjustment step value of the adjustable parameter of the accelerator pedal characteristic and the utilization rate of the standard range of the accelerator pedal opening in the optimization request.

[0060] S220: Determine an intermediate parameter value of the adjustable parameter according to the current adjustment step value and the current parameter value of the adjustable parameter.

[0061] Specifically, the current adjustment step value and the current parameter value of the adjustable parameter may be added, and the result of the addition may be used as the intermediate parameter value of the adjustable parameter. Figure 1B For example, when the accelerator pedal opening is 20% and the engine speed is 3000r / min, the current parameter value of the corresponding adjustable parameter (engine torque) is 26.2, the current adjustment step is 5, and the intermediate parameter value of the adjustable parameter is 31.2.

[0062] S230: Optimize the adjustable parameters according to the intermediate parameter values ​​and the maximum boundary values ​​of the adjustable parameters.

[0063] Specifically, if the intermediate parameter value is less than the maximum boundary value, the intermediate parameter value is used to optimize the adjustable parameter, that is, the intermediate parameter value is used as the optimized parameter value of the adjustable parameter, and the optimized parameter value is used to update the current parameter value; if the intermediate parameter value is equal to or greater than the maximum boundary value, the maximum boundary value is used to optimize the adjustable parameter, that is, the maximum boundary value is used as the optimized parameter value of the adjustable parameter, and the optimized parameter value is used to update the current parameter value.

[0064] The technical solution of this embodiment is to determine the current adjustment step value of the adjustable parameter according to the maximum adjustment step value of the adjustable parameter of the accelerator pedal characteristic and the utilization rate of the standard range of the accelerator pedal opening in the optimization request when receiving the optimization request for the accelerator pedal characteristic associated with the target driving mode, and then determine the intermediate parameter value of the adjustable parameter according to the current adjustment step value and the current parameter value of the adjustable parameter, and then optimize the adjustable parameter according to the intermediate parameter value and the maximum boundary value of the adjustable parameter. The above technical solution realizes the differentiation and intelligence of the optimization of the engine throttle characteristic, limits the adjustable parameter by the maximum boundary value, and while meeting the user's power requirements, it also avoids the situation where the adjustable parameter is infinitely increased and causes accidents.

[0065] Embodiment 3

[0066] Figure 3 This is a flow chart of a method for optimizing engine throttle pedal characteristics according to the third embodiment of the present invention. This embodiment is applicable to the situation of how to optimize the engine throttle pedal characteristics. The method can be executed by an optimization device for engine throttle pedal characteristics. The device can be implemented in the form of hardware and / or software and can be integrated into an electronic device that carries the optimization function of the engine throttle pedal characteristics, such as the cloud. Figure 3 As shown, the method for optimizing the engine throttle pedal characteristics of this embodiment may include:

[0067] S310. Determine a usage rate of the standard range of accelerator pedal opening of the target vehicle in the target driving mode based on a first usage time of the target vehicle in the target driving mode and a second usage time of the target vehicle in the standard range of accelerator pedal opening in the target driving mode.

[0068] In this embodiment, the first use time refers to the cumulative time that the user uses the target driving mode while driving the target vehicle. The second use time refers to the cumulative time that the user uses the standard range of accelerator pedal opening in the target driving mode while driving the target vehicle.

[0069] The so-called standard range of accelerator pedal opening refers to the range of accelerator pedal opening under the target driving mode adopted within the set duration during the use of the vehicle for all vehicles of the same vehicle as the target vehicle. For example, the cloud can collect the target usage duration and target accelerator pedal opening information of the target driving mode of the target vehicle model during driving. Specifically, the cloud can collect the target usage duration and target accelerator pedal opening information of the target driving mode of the target vehicle model during driving by the user through big data embedding; according to the target accelerator pedal opening information and the target usage duration, determine the standard range of accelerator pedal opening of the target driving mode. For example, for all vehicle users of vehicle model A, the total time of using the target driving mode is 100h, among which the target usage duration of the driving pedal opening range of 0-50% is 90h, then the standard range of accelerator pedal opening corresponding to the target driving mode is set to 0-50%.

[0070] Specifically, the ratio of the first usage time to the second usage time may be used as the usage rate of the standard range of the accelerator pedal opening of the target vehicle in the target driving mode.

[0071] S320: If it is identified that the first usage duration exceeds the set duration and the usage rate is less than the set value, it is determined that the target vehicle has a power demand under the target driving mode.

[0072] In fact, the set duration and the set value can be set by those skilled in the art according to actual needs, for example, the set duration is 100 hours and the set value is 90%.

[0073] Specifically, if it is identified that the first usage time exceeds the set time and the usage rate is less than the set value; that is, when the user is driving the target vehicle, the standard range of the accelerator pedal opening under the target driving mode can no longer meet the user's power needs, then it is determined that the target vehicle has the power needs under the target driving mode.

[0074] S330: Send an optimization request to the target vehicle, so that the target vehicle optimizes the engine accelerator pedal characteristics according to the optimization request.

[0075] Specifically, the cloud sends an optimization request to the target vehicle; correspondingly, the target vehicle can optimize the engine accelerator pedal characteristics according to the optimization request.

[0076] The technical solution of the embodiment of the present invention determines the usage rate of the target vehicle's accelerator pedal opening standard range in the target driving mode according to the first usage time of the target vehicle using the target driving mode and the second usage time of the target vehicle using the accelerator pedal opening standard range in the target driving mode. If it is identified that the first usage time exceeds the set time and the usage rate is less than the set value, it is determined that the target vehicle has a dynamic demand in the target driving mode, and then an optimization request is sent to the target vehicle so that the target vehicle optimizes the engine accelerator pedal characteristics according to the optimization request. The above technical solution realizes the differentiation and intelligence of the engine throttle characteristic optimization by real-time monitoring whether the target vehicle has a dynamic demand so that the target vehicle automatically optimizes the engine accelerator pedal characteristics of the target driving mode.
