[0002] The pedal ratio refers to the relationship between the pedal stroke and the driving torque and brake fluid pressure. Specifically, when the user presses the brake pedal or the accelerator pedal, it is the proportional relationship between the pedal stroke and the vehicle's power response (for example, the generated driving force or braking force). Currently, for both the accelerator pedal and the brake pedal, the pedal ratio of the vehicle is fixed, which is difficult to meet the diverse needs of users and thus reduces the user's driving experience.

[0038] Next, the technical solutions in the present application will be clearly and elaborately described in conjunction with the accompanying drawings. Among them, in the description of the embodiments of the present application, unless otherwise specified, " / " means "or". For example, A / B can represent A or B. The "and / or" in the text is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality" means two or more than two.
[0039] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and should not be construed as implying or suggesting relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.
[0040] The pedal ratio refers to the relationship between the pedal travel and the driving torque and the brake fluid pressure. Specifically, when the user presses the brake pedal or the accelerator pedal, it is the proportional relationship between the pedal travel and the vehicle's power response (e.g., the generated driving force or braking force). Currently, whether it is the accelerator pedal or the brake pedal, the pedal ratio of the vehicle is fixed, which is difficult to meet the diverse needs of users and thus reduces the user's driving experience.
[0041] Exemplarily, in different driving scenarios, users have different requirements for the vehicle's power response. For example, as Figure 1 shown, Figure 1 This is a schematic diagram of a vehicle driving scenario provided by an embodiment of the present application. As Figure 1 shown in (a) therein, when the vehicle 110 is in an urban congested section, the vehicle 110 needs to start and stop frequently and follow the vehicle in front; at this time, the user's requirement for the vehicle's power response is more inclined to be stable and slow to reduce the sense of jerk and fuel consumption. As Figure 1 shown in (b) therein, when the vehicle 110 is in a high-speed driving scenario, the vehicle needs to quickly respond to the user's acceleration or braking instructions to ensure driving safety. At this time, the user has higher requirements for the vehicle's power response. As Figure 1 shown in (c) therein and Figure 1 shown in (d) therein, when the vehicle 110 is in a mountain road driving scenario, the vehicle needs to cope with complex road conditions and slope changes. When the vehicle is in an uphill road condition, the vehicle needs sufficient power to overcome gravity; when the vehicle is in a downhill road condition, the user needs to precisely control the vehicle speed to prevent slipping or speeding.
[0042] Therefore, in different driving scenarios, if the pedal ratio is a fixed value, it may affect the user's driving comfort. For example, for a vehicle equipped with a by-wire chassis, a fixed pedal ratio is difficult to meet the diverse driving needs of users.
[0043] Therefore, how to intelligently adjust the pedal ratio to improve the user's driving experience is a technical problem that needs to be solved urgently at present.
[0044] In view of this, an embodiment of the present application provides a vehicle control method, device, vehicle, and storage medium. This method can specifically and intelligently adjust the pedal ratio of the target pedal according to the driving environment where the vehicle is currently located and the driver's historical driving habits, so as to meet the diverse needs of users when driving the vehicle, and further improve the user's driving experience.
[0045] To illustrate the technical solution of the present application, the following will be described by means of specific embodiments. The following will be combined with Figures 2 to 3 to describe in detail the vehicle control method provided by the embodiments of the present application.
[0046] It should be understood that the execution subject of the vehicle control method in the embodiments of the present application is not particularly limited. As long as a program that runs the code of the vehicle control method in the embodiments of the present application can communicate according to the vehicle control method in the embodiments of the present application. For example, the execution subject of the vehicle control method provided by the embodiments of the present application can be a vehicle, or a vehicle control device applied to the vehicle, such as a chip.
[0047] Figure 2 is a schematic flowchart of a vehicle control method provided by the embodiments of the present application.
[0048] S201. Obtain the target parameter of the vehicle and the initial pedal ratio of the target pedal.
[0049] Among them, the target parameter includes the current road condition and / or the driving style parameter of the driver.
[0050] Exemplarily, the current road condition can be used to reflect the driving scenario where the vehicle is located, and specifically can include factors such as road type and traffic conditions, which will directly affect the power response requirements of the vehicle and the driving experience of the user.
[0051] For example, the current road condition can include urban congestion sections, high-speed driving scenarios, mountain road driving scenarios, emergency scenarios, and parking scenarios. The urban congestion section can indicate that the vehicle is driving in the city, the road is congested, and the vehicle needs to start and stop frequently and follow the vehicle in front; at this time, the user's requirement for the power response of the vehicle is more inclined to be stable and slow. The high-speed driving scenario can indicate that the vehicle is driving on the highway at a high speed and needs to quickly respond to the user's acceleration or braking instructions to ensure driving safety. The mountain road driving scenario can indicate that the vehicle is driving on a mountain road and needs to cope with complex road conditions and slope changes. The mountain road driving scenario can include uphill driving scenarios and downhill driving scenarios; in the uphill driving scenario, the vehicle needs sufficient power to overcome gravity; in the downhill driving scenario, it is necessary to precisely control the vehicle speed to prevent slipping or speeding. The emergency scenario is used to represent sudden situations such as emergency acceleration or emergency braking, and specifically can include emergency acceleration scenarios and emergency braking scenarios. At this time, the user's requirement for the power response of the vehicle is extremely high, and it is hoped that the vehicle can quickly respond to the driver's instructions. The parking scenario can indicate that the vehicle is performing a parking operation in a parking lot or a narrow road, and it is necessary to precisely control the vehicle speed and distance to avoid colliding with surrounding obstacles.
[0052] Exemplarily, the current road condition of the vehicle can be obtained by obtaining the vehicle's driving state information and the vehicle's external environment information, and determining the current road condition based on the driving state information and the vehicle's external environment information.
[0053] For example, the vehicle's driving state information and external environment information can be collected through sensors installed in the vehicle (such as wheel speed sensors, acceleration sensors, slope sensors, cameras, on-board radars, etc.). Then, the current road conditions can be identified based on the vehicle's driving state information and external environment information.
[0054] For example, if the driving state information determines that the current vehicle speed is low and the acceleration fluctuates greatly, and if the external environment information determines that the surrounding vehicle density is high, then the current road condition is determined to be a city congestion scenario. For another example, if the driving state information determines that the current vehicle speed is high and the acceleration is stable, and if the external environment information determines that there are few surrounding vehicles and obstacles and the road ahead is relatively wide, then the current road condition is determined to be a high-speed driving scenario. For another example, if the driving state information determines that the current wheel speed is decreasing, the acceleration is low, and the slope changes significantly, and if the external environment information identifies the unique terrain features of a mountain road, then the current road condition is determined to be an uphill driving scenario. If the driving state information determines that the current wheel speed is increasing, the acceleration is high, and the slope changes significantly, and if the external environment information identifies the unique terrain features of a mountain road, then the current road condition is determined to be a downhill driving scenario. For example, if the vehicle's acceleration and wheel speed increase significantly based on driving status information, the current road condition is determined to be an emergency acceleration scenario. If the vehicle's acceleration and wheel speed decrease significantly based on driving status information, and an obstacle suddenly appears ahead based on external environment information, the current road condition is determined to be an emergency braking scenario. For another example, if the vehicle's wheel speed and acceleration are close to zero based on driving status information, and the obstacles around the vehicle are determined to be other vehicles, curbs, walls, etc. based on external environment information, the current road condition is determined to be a parking scenario.
[0055] For example, the driver's driving style parameter can be used to reflect the driver's pedaling force (i.e., pedal stroke) when responding to different driving scenarios within a certain driving cycle. The driving style parameter can be used to indicate the driver's style.
[0056] For example, the target pedal can serve as an interface for interacting with the vehicle's powertrain. The target pedal can include a drive pedal and a brake pedal. Specifically, by stepping on the accelerator pedal, the user can request the vehicle to increase driving force to control the vehicle's acceleration and power output; by stepping on the brake pedal, the user can request the vehicle to generate braking force to control the vehicle's deceleration and parking.
[0057] Exemplarily, the initial pedal ratio can be used to represent the initial proportional relationship between the pedal travel and the torque. The initial pedal ratio can be a calibrated preset value, such as a value pre-configured for the vehicle or a value set manually. The embodiments of the present application do not make specific limitations thereto.
[0058] S202. Obtain a pedal ratio adjustment amount based on the target parameter.
[0059] Exemplarily, the pedal ratio adjustment amount can be an amount used to adjust based on the initial pedal ratio of the target pedal. The pedal ratio adjustment amount can be a positive value, a negative value, or zero. The magnitude of the pedal ratio adjustment amount can be specifically determined according to the actual situation.
[0060] It can be understood that through the pedal ratio adjustment amount obtained for the target parameter, when the user is driving the vehicle, it can adapt to different driving needs, thereby improving the user's driving experience.
[0061] Exemplarily, the pedal ratio adjustment amount can include an acceleration pedal ratio adjustment amount and a brake pedal ratio adjustment amount.
[0062] For the specific description of S202, reference can be made to the following embodiments, and details are not described herein again.
[0063] S203. Obtain a target pedal ratio based on the initial pedal ratio and the pedal ratio adjustment amount.
[0064] Among them, the target pedal ratio is used to represent the correlation between the pedal travel and the torque of the target pedal.
[0065] As an example, when the target pedal is the acceleration pedal, the target pedal ratio is used to represent the correlation between the pedal travel of the target pedal and the driving torque.
[0066] As another example, when the target pedal is the brake pedal, the target pedal ratio is used to represent the correlation between the pedal travel of the target pedal and the braking torque.
[0067] Exemplarily, the correlation between the pedal travel of the target pedal and the braking torque can be used to represent the ratio between the pedal travel of the target pedal and the braking torque.
[0068] Exemplarily, the pedal travel can refer to the displacement amount when the user steps on the pedal. The pedal travel is usually expressed as a percentage, such as 0% to 100%. The magnitude of the pedal travel can be used to reflect the degree of the user's demand for vehicle power or braking force.
[0069] For example, when the target pedal ratio is 1:50, stepping on the accelerator pedal by 10% of the pedal travel corresponds to an output torque of 500 Nm; when the pedal ratio is 1:100, the same 10% travel corresponds to a torque of 1000 Nm. That is, when the pedal ratio increases (e.g., from 1:50 to 1:30), the torque generated per unit travel decreases, and a greater pedal travel is required to obtain the same torque; when the pedal ratio decreases (e.g., from 1:50 to 1:100), the torque generated per unit travel increases, and only a smaller pedal travel is needed to obtain the same torque.
[0070] As an example, when the pedal ratio adjustment amount is positive, the pedal ratio adjustment amount can be added to the initial pedal ratio to obtain the target pedal ratio.
[0071] As another example, when the pedal ratio adjustment amount is negative, the pedal ratio adjustment amount can be subtracted from the initial pedal ratio to obtain the target pedal ratio.
[0072] As another example, when the pedal ratio adjustment amount is zero, the value of the initial pedal ratio can be kept unchanged to obtain the target pedal ratio.
[0073] S204. Control the target pedal based on the target pedal ratio.
[0074] Exemplarily, when the target pedal ratio is obtained, the vehicle control system can send it to the controller of the drive-by-wire chassis of the vehicle. Then, the controller of the drive-by-wire chassis will calculate the corresponding driving torque and braking torque according to 1. the target pedal ratio and the actual stepping travel of the user. Next, 2. these torque values will be output to actuators such as the drive motor or the brake booster motor to achieve the output of the corresponding driving torque and braking torque.
[0075] In the embodiments of the present application, by obtaining the target parameters of the vehicle and the initial pedal ratio of the target pedal, and obtaining the pedal ratio adjustment amount based on the target parameters; then based on the initial pedal ratio and the pedal ratio adjustment amount, obtaining the target pedal ratio; and further controlling the target pedal based on the target pedal ratio; compared with the related art where the pedal ratios of the accelerator pedal and the brake pedal are fixed values, since this solution can take into account the current road conditions and / or driving style parameters of the vehicle, and the current road conditions can reflect the driving scenarios where the vehicle is located, and the driving style parameters can reflect the driving habits of the user, and thus can adjust the pedal ratio of the target pedal in a targeted and intelligent manner according to the current driving environment of the vehicle and the historical driving habits of the driver, so as to meet the diverse needs of the user when driving the vehicle, thereby improving the driving experience of the user.
[0076] In a possible embodiment of the present application, the above S202 includes the following three methods:
[0077] Mode 1. If the target parameter includes the current road condition, determine the first pedal ratio adjustment amount corresponding to the road condition type of the current road condition as the pedal ratio adjustment amount.
[0078] Exemplarily, when the target parameter includes the current road condition, the first pedal adjustment amount corresponding to the road condition type of the current road condition can be determined based on the current road condition; then use the first pedal adjustment amount as the pedal ratio adjustment amount.
[0079] As an example, when the road condition type of the current road condition is an urban congested section, for the accelerator pedal, the accelerator pedal ratio can be increased to make the accelerator pedal more stable, facilitating the vehicle to follow the vehicle slowly and smoothly, thereby reducing the jerks and fuel consumption caused by frequent starts and stops; for the brake pedal, the brake pedal ratio can be increased to make the braking more stable, and the user can precisely control the vehicle speed and distance by gently stepping on the brake pedal, avoiding discomfort to passengers and rear-end accidents caused by sudden braking.
[0080] As another example, when the road condition type of the current road condition is a high-speed driving scenario, for the accelerator pedal, the accelerator pedal ratio can be increased to make the pedal response more stable. When overtaking or accelerating is needed, the user can step on the pedal deeply to obtain an obvious power boost; for the brake pedal, the brake pedal ratio can be increased so that when driving at high speed, the user can more precisely control the braking torque through a larger brake pedal ratio to ensure the stability and safety of braking.
[0081] As another example, when the road condition type of the current road condition is an uphill driving scenario on a mountain road, for the accelerator pedal, the accelerator pedal ratio can be decreased to make the accelerator pedal response more sensitive, so that the vehicle can obtain power in time, thereby preventing the vehicle from slipping due to insufficient power; for the brake pedal, the brake pedal ratio can be increased; because the vehicle's own power will assist the vehicle to decelerate, a larger brake pedal ratio enables the user to precisely control the braking force.
[0082] As another example, when the road condition type of the current road condition is a downhill driving scenario on a mountain road, for the accelerator pedal, the accelerator pedal ratio can be increased to avoid excessive vehicle speed caused by accidentally stepping on the accelerator pedal; for the brake pedal, the brake pedal ratio can be increased to provide a stable and continuous braking force, avoiding the situation where the braking force is too large due to too small a brake pedal ratio, resulting in wheel lock.
[0083] As another example, when the road condition type of the current road condition is an emergency acceleration scenario, for the accelerator pedal, the accelerator pedal ratio can be reduced to the lowest level, enabling the vehicle to quickly obtain maximum power and get rid of danger and avoid collisions as soon as possible; optionally, for the brake pedal, the brake pedal ratio can be increased to the highest level to prevent the user from accidentally stepping on the brake pedal and causing the vehicle to stop.
[0084] As another example, when the road condition type of the current road condition is an emergency braking scenario, for the accelerator pedal, the accelerator pedal ratio can be increased to the highest level to prevent the user from accidentally stepping on the accelerator pedal and causing the vehicle speed to increase; for the brake pedal, the brake pedal ratio can be reduced to the lowest level, enabling the vehicle to quickly obtain strong braking force and thus minimizing the braking distance to the greatest extent.
[0085] As another example, when the road condition type of the current road condition is a parking scenario, for the accelerator pedal, the accelerator pedal ratio can be increased to a relatively high level to make the pedal response more stable, facilitating precise control of the vehicle speed and distance and avoiding collisions with surrounding obstacles due to excessive power; for the brake pedal, the brake pedal ratio can be increased to a relatively high level to make the braking force increase slowly with the pedal stroke, thus making the parking action smoother and improving the ride comfort in the parking scenario.
[0086] Exemplarily, different road condition types of the current road condition may correspond to different accelerator pedal ratio adjustment amounts and brake pedal ratio adjustment amounts. That is, there is a corresponding relationship between the road condition type of the current road condition and each pedal ratio adjustment amount. For example, as shown in Table 1, Table 1 is a corresponding relationship table between the road condition type of the current road condition provided in the embodiment of the present application and the accelerator pedal ratio adjustment amount and the brake pedal ratio adjustment amount. It should be noted that Table 1 only exemplarily illustrates the corresponding relationship between the road condition type of the current road condition and the accelerator pedal ratio adjustment amount and the brake pedal ratio adjustment amount, and the specific corresponding relationship can be determined by the actual scenario.
[0087] Table 1 Corresponding relationship table between the road condition type of the current road condition and each pedal ratio adjustment amount
[0088] Current road conditions Accelerator pedal ratio adjustment amount Brake pedal ratio adjustment amount Urban congested sections +0.02 +0.02 High-speed driving scenario +0.01 +0.01 Uphill driving scenario on mountain roads -0.015 +0.015 Downhill driving scenario on mountain roads +0.015 +0.015 Emergency acceleration scenario +0.03 -0.03 Emergency braking scenario -0.03 +0.03 Parking scenario +0.02 +0.02 ... ...
[0089] For example: when the road condition type of the current road condition is an urban congested section, the acceleration pedal ratio adjustment amount is +0.02, and the brake pedal ratio adjustment amount is +0.02; when the road condition type of the current road condition is a highway driving scenario, the acceleration pedal ratio adjustment amount is +0.01, and the brake pedal ratio adjustment amount is +0.01; when the road condition type of the current road condition is an uphill driving scenario on a mountain road, the acceleration pedal ratio adjustment amount is -0.015, and the brake pedal ratio adjustment amount is +0.015; when the road condition type of the current road condition is a downhill driving scenario on a mountain road, the acceleration pedal ratio adjustment amount is +0.015, and the brake pedal ratio adjustment amount is +0.015; when the road condition type of the current road condition is an emergency acceleration scenario, the acceleration pedal ratio adjustment amount is +0.03, and the brake pedal ratio adjustment amount is -0.03; when the road condition type of the current road condition is an emergency braking scenario, the acceleration pedal ratio adjustment amount is -0.03, and the brake pedal ratio adjustment amount is +0.03; when the road condition type of the current road condition is a parking scenario, the acceleration pedal ratio adjustment amount is +0.02, and the brake pedal ratio adjustment amount is +0.02.
[0090] For example, when the road condition type of the current road condition is an urban congested section, if the initial pedal ratio of the acceleration pedal and the initial pedal ratio of the brake pedal are 0.03, based on the initial pedal ratio of the acceleration pedal and the pedal ratio adjustment amount of the acceleration pedal, the target pedal ratio of the acceleration pedal is obtained as 0.05; at this time, stepping on the acceleration pedal by 10% of the pedal travel corresponds to an output drive torque of 500 Nm; and, based on the initial pedal ratio of the brake pedal and the pedal ratio adjustment amount of the brake pedal, the target pedal ratio of the brake pedal is obtained as 0.05; at this time, stepping on the brake pedal by 10% of the pedal travel corresponds to an output braking torque of 500 Nm.
[0091] As an example, determining the first pedal ratio adjustment amount corresponding to the road condition type of the current road condition includes: obtaining the pedal ratio adjustment amount corresponding to the type identifier based on the type identifier of the current road condition; determining the pedal ratio adjustment amount corresponding to the type identifier as the first pedal ratio adjustment amount.
[0092] Exemplarily, the type identifier is used to represent the road condition type of the current road condition.
[0093] Exemplarily, the correspondence between the road condition type of the current road condition and each pedal ratio adjustment amount can be obtained through the correspondence between the type identifier and each pedal ratio adjustment amount. For example, through the type identifier of the current road condition, each pedal ratio adjustment amount corresponding to the current road condition can be determined from the correspondence between the type identifier and each pedal ratio adjustment amount.
[0094] Exemplarily, the type identifier can be represented in the form of a code or a string. For example, as shown in Table 2, Table 2 is a correspondence table between the current road conditions and the type identifier provided by the embodiments of the present application. It should be noted that Table 2 only exemplarily illustrates the correspondence between the current road conditions and the type identifier, and the specific correspondence can be determined by the actual scenario.
[0095] Table 2 Correspondence Table between Current Road Conditions and Type Identifiers
[0096]
[0097]
[0098] For example, the type identifier corresponding to the urban congested section can be "C"; the type identifier corresponding to the high-speed driving scenario can be "H"; the type identifier corresponding to the uphill driving scenario on the mountain road can be "HU"; the type identifier corresponding to the downhill driving scenario on the mountain road can be "HD"; the type identifier corresponding to the emergency acceleration scenario can be "EA"; the type identifier corresponding to the emergency braking scenario can be "EB"; the type identifier corresponding to the parking scenario can be "P".
[0099] It can be understood that since the type identifier can be used to reflect the current road conditions, through the type identifier of the current road conditions, the pedal ratio adjustment amount corresponding to the type identifier can be quickly obtained, and then the first pedal ratio adjustment amount can be quickly determined.
[0100] Method 2. If the target parameter includes a driving style parameter, determine the second pedal ratio adjustment amount corresponding to the driving style parameter as the pedal ratio adjustment amount.
[0101] Exemplarily, in the case where the target parameter includes a driving style parameter, the second pedal adjustment amount corresponding to the driving style parameter can be determined based on the driving style parameter; then the second pedal adjustment amount is used as the pedal ratio adjustment amount.
[0102] Exemplarily, the driving style parameter can be used to indicate the user's driving style. The driving style can refer to the specific driving habits and behavior patterns demonstrated by the user during the driving process, such as the degree of stepping on the accelerator pedal or the brake pedal.
[0103] For example, the user's driving style can include a conservative driving style and an aggressive driving style. The conservative driving style can refer to the user's tendency to adopt a more cautious and stable driving method during the driving process, such as being usually slow and stable when accelerating and braking, and not suddenly accelerating or making an emergency brake. The aggressive driving style can refer to the user's tendency to adopt a more active and aggressive driving method during the driving process, such as being usually rapid and decisive when accelerating and braking, and may frequently use high acceleration and emergency braking.
[0104] As an example, when the driving style parameter indicates a conservative driving style, the acceleration pedal ratio of the acceleration pedal and the braking pedal ratio of the braking pedal can be increased. This can increase the stability of the power output and the braking output.
[0105] As another example, when the driving style parameter indicates an aggressive driving style, the acceleration pedal ratio of the acceleration pedal and the braking pedal ratio of the braking pedal can be decreased. This can increase the speed of the power output and the braking output.
[0106] It can be understood that through the second pedal ratio adjustment amount corresponding to the driving style parameter, the target pedal ratio can be made to fit the user's driving habits, so as to improve the user's driving experience.
[0107] Exemplarily, the driving style parameter can be represented by a digital signal (for example, "0" or "1"), a level signal (for example, a high level signal or a low level signal) to represent the driver's driving style. For example, taking the digital signal as an example: when the driving style parameter indicates "0", it can represent a conservative driving style, and when the driving style parameter indicates "1", it can represent an aggressive driving style; or, when the driving style parameter indicates "0", it can represent an aggressive driving style, and when the driving style parameter indicates "1", it can represent a conservative driving style. The embodiments of the present application do not make specific limitations in this regard. Again, taking the level signal as an example: when the driving style parameter indicates a low level signal, it can represent a conservative driving style, and when the driving style parameter indicates a high level signal, it can represent an aggressive driving style; or, when the driving style parameter indicates a low level signal, it can represent an aggressive driving style, and when the driving style parameter indicates a high level signal, it can represent a conservative driving style. The embodiments of the present application do not make specific limitations in this regard.
[0108] Exemplarily, different driving style parameters may correspond to different acceleration pedal ratio adjustment amounts and braking pedal ratio adjustment amounts. That is, there is a corresponding relationship between the driving style parameter and each pedal ratio adjustment amount. For example, as shown in Table 3, Table 3 is a corresponding relationship table between the driving style parameter and the acceleration pedal ratio adjustment amount and the braking pedal ratio adjustment amount provided by the embodiments of the present application. It should be noted that Table 3 only exemplarily illustrates the corresponding relationship between the driving style parameter and the acceleration pedal ratio adjustment amount and the braking pedal ratio adjustment amount, and the specific corresponding relationship can be determined by the actual scenario.
[0109] It should be noted that the driving style parameter can be represented in the form of a digital signal, wherein when the driving style parameter indicates "0", it can represent a conservative driving style, and when the driving style parameter indicates "1", it can represent an aggressive driving style.
[0110] Table 3 Correspondence Table between Driving Style Parameters and Adjustment Amounts of Each Pedal Ratio
[0111]
[0112]
[0113] For example: When the driving style parameter indicates "0", it means that the driving style parameter indicates a conservative driving style, the adjustment amount of the accelerator pedal ratio is +0.01, and the adjustment amount of the brake pedal ratio is +0.01; when the driving style parameter indicates "1", it means that the driving style parameter indicates an aggressive driving style, the adjustment amount of the accelerator pedal ratio is -0.01, and the adjustment amount of the brake pedal ratio is -0.01;
[0114] For example, in the case of a conservative driving style, if the initial pedal ratios of the accelerator pedal and the brake pedal are 0.03, based on the initial pedal ratio of the accelerator pedal and the adjustment amount of the accelerator pedal ratio, the target pedal ratio of the accelerator pedal is 0.04; at this time, stepping on the accelerator pedal by 10% of the pedal stroke corresponds to an output drive torque of 400 Nm; and, based on the initial pedal ratio of the brake pedal and the adjustment amount of the brake pedal ratio, the target pedal ratio of the brake pedal is 0.04; at this time, stepping on the brake pedal by 10% of the pedal stroke corresponds to an output braking torque of 400 Nm.
[0115] As an example, the method provided by the embodiments of the present application further includes: if the target parameter includes a driving style parameter, obtaining historical pedal parameters; detecting whether the historical pedal stroke is less than or equal to a preset pedal stroke; if the historical pedal stroke is less than or equal to the preset pedal stroke, determining that the driving style parameter indicates a conservative driving style; if the historical pedal stroke is greater than the preset pedal stroke, determining that the driving style parameter indicates an aggressive driving style.
[0116] Wherein, the historical pedal parameter is used to represent the average value of the historical pedal strokes of the target pedal within a preset duration.
[0117] Exemplarily, the preset duration can be a calibrated value; it can be a value pre-configured in the vehicle or a value set manually, and the embodiments of the present application do not make specific limitations on this.
[0118] Exemplarily, the historical pedal parameter is used to represent the average value of the historical pedal strokes of the target pedal within a preset duration (for example, in the past month); this average value can reflect the user's pedal operation habits within a month.
[0119] For example, the sensors on the vehicle can record the user's target pedal operation data in real time, including the time and pedal stroke of each pedal step, etc.; then calculate the historical stroke average of the target pedal to obtain the historical pedal parameters.
[0120] For example, the preset pedal stroke may be a calibrated value, a value pre-configured by the vehicle, or a manually set value, which is not specifically limited in the present embodiment. For example, the preset pedal stroke may be 60%.
[0121] The following description uses the accelerator pedal as an example; the description of the accelerator pedal can be referred to for the brake pedal and will not be repeated here.
[0122] As an example, if the historical pedal travel average (e.g., 50%) is less than the preset pedal travel (e.g., 60%), it can be determined that the user is relatively cautious in pedal operation and tends to accelerate slowly and smoothly, and then the driving style parameter is determined to indicate a conservative driving style.
[0123] As another example, if the historical pedal travel average (e.g., 65%) is greater than the preset pedal travel (e.g., 60%), it can be determined that the user is more decisive and quick in pedal operation and tends to accelerate quickly, and then the driving style parameter is determined to indicate an aggressive driving style.
[0124] It is understandable that by obtaining and analyzing the user's historical pedal parameters, the user's driving style type can be accurately identified, and the pedal ratio can be adjusted specifically according to the user's driving style type to improve the user's driving experience.
[0125] In an embodiment of the present application, through the first pedal ratio adjustment amount corresponding to the current road condition, the target pedal ratio can be adapted to the external driving environment of the vehicle; through the second pedal ratio adjustment amount corresponding to the driving style parameter, the target pedal ratio can be adapted to the user's driving habits, thereby realizing targeted and intelligent adjustment of the pedal ratio of the target pedal.
[0126] Method 3. If the target parameters include the current road condition and the driving style parameters, determine the first pedal ratio adjustment amount corresponding to the road condition type of the current road condition; determine the second pedal ratio adjustment amount corresponding to the driving style parameter; and obtain the pedal ratio adjustment amount based on the first pedal ratio adjustment amount and the second pedal ratio adjustment amount.
[0127] Regarding how to determine the first pedal ratio adjustment amount and the second pedal ratio adjustment amount, reference may be made to the above embodiment, which will not be described in detail here.
[0128] As an example, when determining the first pedal ratio adjustment amount and the second pedal ratio adjustment amount, the pedal ratio adjustment amount can be obtained by calculating the average value between the first pedal ratio adjustment amount and the second pedal ratio adjustment amount.
[0129] As another example, when determining the first pedal ratio adjustment amount and the second pedal ratio adjustment amount, the pedal ratio adjustment amount can be obtained by calculating the weighted average value between the first pedal ratio adjustment amount and the second pedal ratio adjustment amount. For specific reference, please refer to the following embodiments and will not be elaborated here.
[0130] As another example, when determining the first pedal ratio adjustment amount and the second pedal ratio adjustment amount, the larger value or the smaller value of the two pedal ratio adjustment amounts can also be determined by comparing the magnitudes between the first pedal ratio adjustment amount and the second pedal ratio adjustment amount.
[0131] As another example, when determining the first pedal ratio adjustment amount and the second pedal ratio adjustment amount, the priority relationship between the current road condition and the driving style parameter can also be compared; the pedal ratio adjustment amount corresponding to the target parameter with a higher priority is determined as the pedal ratio adjustment amount. For example, if the priority of the current road condition is higher than the priority of the driving style parameter, the first pedal ratio adjustment amount is determined as the pedal ratio adjustment amount. Another example is that if the priority of the driving style parameter is higher than the priority of the current road condition, the second pedal ratio adjustment amount is determined as the pedal ratio adjustment amount. It should be noted that this priority relationship can be a fixed priority relationship or can be adjusted in real time according to the driving situation.
[0132] In the embodiments of the present application, by combining the current road condition and the driving style parameter, the pedal ratio adjustment amount can be determined while taking into account both the external driving environment where the vehicle is located and the driving habits of the user, thereby further improving the intelligence of pedal adjustment to meet the diverse needs of the user when driving the vehicle.
[0133] In a possible embodiment of the present application, obtaining the pedal ratio adjustment amount based on the first pedal ratio adjustment amount and the second pedal ratio adjustment amount includes: determining a first weight coefficient corresponding to the current road condition and a second weight coefficient corresponding to the driving style parameter; obtaining the pedal ratio adjustment amount based on the product of the first pedal ratio adjustment amount and the first weight coefficient and the product of the second pedal ratio adjustment amount and the second weight coefficient.
[0134] Exemplarily, the first weight coefficient is used to reflect the importance degree of the current road condition to the pedal ratio adjustment. Correspondingly, the second weight coefficient is used to reflect the importance degree of the driving style parameter to the pedal ratio adjustment.
[0135] As an example, the first weight coefficient and the second weight coefficient can be machine calibration values, which can be values configured for the vehicle or values set manually. The embodiments of the present application do not make specific limitations on this.
[0136] As another example, the first weight coefficient and the second weight coefficient can also be adjusted in real time according to factors such as the driving conditions and complexity of the vehicle. For example, in the case where the current road condition is an emergency braking scenario, the first weight coefficient will be much greater than the second weight coefficient.
[0137] For example: If the current road condition is a high-speed driving scenario, the first pedal ratio adjustment amount of the accelerator pedal is +0.01, and the first pedal ratio adjustment amount of the brake pedal is +0.01; if the driving style parameter indicates an aggressive driving style, the second pedal ratio adjustment amount of the accelerator pedal is -0.01, and the second pedal ratio adjustment amount of the brake pedal ratio is -0.01. When the first weight coefficient is 0.8 and the second weight coefficient is 0.6, the product of the first pedal ratio adjustment amount of the accelerator pedal and the first weight coefficient is +0.008, and the product of the second pedal ratio adjustment amount and the second weight coefficient is -0.006; for the brake pedal, the product of the first pedal ratio adjustment amount and the first weight coefficient is +0.008, and the product of the second pedal ratio adjustment amount and the second weight coefficient is -0.006. Then, the pedal ratio adjustment amount of the accelerator pedal is 0.002, and the pedal ratio adjustment amount of the brake pedal is 0.002.
[0138] In the embodiments of the present application, through the respective weight coefficients of the current road condition and the driving style parameter, the importance of the current road condition and the driving style parameter for the pedal ratio adjustment can be determined respectively, thereby improving the scene adaptability and data reliability of the pedal ratio adjustment amount, and further improving the intelligence of the pedal adjustment to meet the diverse needs of users when driving the vehicle.
[0139] In a possible embodiment of the present application, the method provided by the embodiments of the present application further includes: if the pedal ratio adjustment amount is greater than zero, output a first prompt message; if the pedal ratio adjustment amount is less than zero, output a second prompt message.
[0140] Among them, the first prompt message is used to prompt that the pedal ratio of the target pedal increases, and the second prompt message is used to prompt that the pedal ratio of the target pedal decreases.
[0141] Exemplarily, the first prompt message and the second prompt message can be prompt messages displayed on the display interface of the in-vehicle system, or voice messages output through the speaker in the vehicle. Of course, they can also be messages output through other means. The embodiments of the present application do not make specific limitations on this.
[0142] As an example, when it is detected that the pedal ratio adjustment amount is greater than zero, it indicates that the target pedal ratio increases based on the initial pedal ratio. At this time, a first prompt message can be output, such as "The pedal ratio of the brake pedal has increased. Please get used to the new pedal feeling.", "The pedal ratio of the accelerator pedal has increased. Please get used to the new pedal feeling.".
[0143] As another example, when it is detected that the pedal ratio adjustment amount is less than zero, it indicates that the target pedal ratio decreases based on the initial pedal ratio. At this time, a second prompt message can be output, such as "The pedal ratio of the brake pedal has decreased. Please get used to the new pedal feeling.", "The pedal ratio of the accelerator pedal has decreased. Please get used to the new pedal feeling.".
[0144] In the embodiments of the present application, by detecting the positive or negative of the pedal ratio adjustment amount, a prompt message corresponding to the pedal ratio adjustment amount is output, so that the user can timely understand the change of the pedal ratio, and then adapt to the adjusted driving feeling, further improving the user's driving experience.
