[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In recent years, with the development of vehicle intelligence and personalization, cars are no longer just a means of transportation, but have gradually evolved into a mobile intelligent tool, which has both tool attributes and entertainment and rest attributes. The types of cars are also increasing day by day, and the force value of the electronic accelerator pedal of the car is usually not adjustable after the product development. When the electronic accelerator pedal needs to adjust the pedal force, it often needs to be newly developed, and after development, the pedal force value is fixed, and its development workload is large, the cycle is long, and the cost is high. In summary, different models currently have different requirements for pedal force, and it is necessary to continuously develop new accelerator pedals to adapt to model development; the same car cannot meet the pedal force requirements of all users, and cannot be personalized according to user preferences to meet user needs; at the same time, the existing technology requires manual removal of the pedal for manual adjustment, and can only be roughly adjusted. The user cannot accurately know the specific pedal force value after adjustment, the adjustment process is complicated and inaccurate, and the user interaction experience is poor.

[0029] Based on this, the pedal force adjustment method, device, automobile and medium provided in the embodiments of the present invention can meet the pedal force requirements of different users and improve the user experience and satisfaction.

[0030] To facilitate understanding of this embodiment, a pedal force adjustment method disclosed in an embodiment of the present invention is first introduced in detail. The method can be implemented by a vehicle control unit (VCU) of a vehicle, see Figure 1 The flowchart of a pedal force adjustment method shown in FIG. 1 illustrates that the method mainly includes the following steps S101 to S103:

[0031] Step S101: receiving an adjustment instruction input by a driver; wherein the adjustment instruction carries information for changing the pedal force value, and determining a target pedal force value based on the information.

[0032] In one embodiment, the driver can input an adjustment instruction through the central control panel of the car, and the adjustment instruction carries information for changing the pedal force value, such as gear information, driving style information, etc. Based on this information, the corresponding target pedal force value can be determined. Specifically, a pedal force adjustment button can be set on the central control panel, and the user can determine the required target pedal force value by sliding the pedal force adjustment button, and the target pedal force value is displayed on the central control panel, and the target pedal force value is sent to the VCU at the same time; a driving style adjustment button can also be set on the central control panel, and the user can determine the required driving style by sliding the driving style adjustment button, and send the determined driving style to the VCU. In the embodiment of the present application, the pedal force value corresponding to each driving style is pre-stored in the VCU, and the VCU can search and determine the target pedal force value according to the received driving style; a button can also be set on the central control panel, and the user can directly input the required target pedal force value through the button, and the input target pedal force value is sent to the VCU.

[0033] Step S102: Determine the rotation time of the motor based on the target pedal force value.

[0034] In the embodiment of the present application, the VCU is connected to the motor of the accelerator pedal through a motor harness. The VCU controls the rotation of the motor to drive the worm rod at its head to rotate, so that the integrated worm gear spring seat rises or falls, so as to adjust the spring preload and adjust the size of the pedal force. During the selection and design, the motor speed can be set in advance so that the vehicle controller can accurately control the motor rotation angle to adjust the pedal force value. Specifically, the motor rotation angle can be controlled by controlling the motor rotation time under the premise of knowing the motor speed, so that the integrated worm gear spring seat rises or falls, and the spring deformation changes, so as to adjust the spring preload and adjust the size of the pedal force. Based on this, when the VCU in the embodiment of the present invention receives the target pedal force value input by the driver, it can calculate the rotation time of the motor, or store the corresponding relationship table between the pedal force value and the rotation time in the VCU in advance, and determine the rotation time of the lower motor corresponding to the target pedal force value by looking up the table, so as to control the adjustment of the pedal force value.

[0035] Step S103: Control the motor to rotate for a rotation time.

[0036] In specific implementation, the VCU controls the motor to rotate to reach the rotation time, thereby driving the worm rod at its head to rotate, so that the integrated worm gear spring seat rises or falls, so as to adjust the spring preload and adjust the pedal force. Specifically, when the integrated worm gear spring seat rises, the integrated worm gear spring seat compresses the spring, thereby increasing the preload of the spring and increasing the pedal force of the accelerator pedal. When the integrated worm gear spring seat falls, the integrated worm gear spring seat drives the spring to lengthen, thereby reducing the preload of the spring and reducing the pedal force of the accelerator pedal.

[0037] The pedal force adjustment method provided in the embodiment of the present invention enables the driver to input a target pedal force value according to his or her own preference, and the pedal force value is adjusted according to the driver's input, thereby meeting the pedal force requirements of different drivers and improving the driver's experience and satisfaction; at the same time, the adjustment instructions input by the driver can be displayed through the central control panel, and the central control panel displays the pedal force value adjusted by the driver in real time, which enables the driver to accurately know the size of the pedal force and increases the driver's interactive experience.

[0038] The embodiment of the present invention further provides a method for calculating the pedal force value. Specifically, the calculation formula of the spring force is: Ft=kx, wherein Ft represents the spring force, k represents the elastic coefficient, which is a constant, and x represents the spring deformation.

[0039] The spring deformation x is adjusted by the worm gear at the motor head, and the calculation formula is: x=p*n / Z, where p represents the pitch of the worm screw, n represents the number of worm rotations, and Z represents the worm gear transmission ratio.

[0040] The number of turbine rotations n can be controlled by the VCU, and the calculation formula is: n=r*t, where r represents the motor speed and t represents the motor rotation time, that is, the motor working time.

[0041] Assuming that the pedal lever ratio is i (i is a constant), in summary, the calculation formula for the pedal force is: F = k*p*r*t / (Z*i), wherein F represents the pedal force, k and i are constants, and p, r and Z have been determined in the selection and design according to different needs. Therefore, the VCU only needs to control the forward or reverse rotation time of the motor according to the preference requirements input by the driver (that is, the adjustment command) to adjust the pedal force. Among them, the forward rotation of the motor can make the integrated worm gear spring seat rise, the spring is compressed, and the pedal force value increases. The reverse rotation of the motor can make the integrated worm gear spring seat drop, the spring is stretched, and the pedal force value decreases.

[0042] In this embodiment, before adjusting the pedal force, the accelerator pedal will have an initial pedal force, that is, the current pedal force value. To achieve the target pedal force value, you only need to increase or decrease the current pedal force value accordingly. For example: the current pedal force value is 5N, the target pedal force value is 10N, and the pedal force value to be adjusted is 5N, that is, the pedal force value is increased by 5N on the basis of the current pedal force value. Based on this, when determining the rotation time of the motor based on the target pedal force value, the following methods can be used, including but not limited to: obtaining the current pedal force value, and determining the pedal force difference between the current pedal force value and the target pedal force value; using a preset pedal force algorithm, the pedal force difference is calculated to obtain the rotation time of the motor. Specifically, according to the pedal force value calculation formula: F = k*p*r*t / (Z*i), the rotation time of the motor is obtained.

[0043] In order to ensure driving safety, the pedal force adjustment method provided in the embodiment of the present invention only allows the pedal force value of the accelerator pedal to be adjusted when the vehicle is stopped. Therefore, vehicle speed judgment is added in the implementation of the present invention. After receiving the adjustment command input by the driver, the VCU needs to obtain the current speed of the vehicle and determine whether the current speed is zero. If the current speed is zero, the rotation time of the motor is determined based on the target pedal force value.

[0044] Furthermore, in order to meet the needs of different drivers and improve the driver's interactive experience, the present invention provides the following three methods for receiving the adjustment instructions input by the driver:

[0045] Method 1: Enter the target pedal force value by sliding the adjustment button

[0046] Specifically, monitor whether a first sliding operation occurs in a preset area of ​​the central control panel; wherein the preset area includes a pedal force adjustment button, and the first sliding operation is a sliding operation on the pedal force adjustment button; if the first sliding operation occurs in the preset area, determine the sliding end point of the first sliding operation, and determine the target pedal force value corresponding to the sliding end point.

[0047] See also Figure 2 As shown in the schematic diagram of the central control panel, a pedal force adjustment area or page, i.e., a preset area, can be set on the central control panel. A pedal force adjustment button is set on the preset area. The pedal force adjustment button can slide. Different positions correspond to different pedal force values. The driver can input the required pedal by sliding the pedal force adjustment button. When the VCU detects the driver's first sliding operation on the pedal force adjustment button, the corresponding target pedal force value can be determined according to the position of the sliding end point.

[0048] In one embodiment, Figure 2As shown, multiple pedal force gears can be set in the preset area. When adjusting, the driver can directly slide the pedal force adjustment button to the corresponding pedal force gear value as needed. After the VCU detects the driver's first sliding operation on the pedal force adjustment button, it can determine the target pedal force gear corresponding to the sliding end point, and determine the target pedal force value corresponding to the target pedal force gear. For example: assuming that the pedal force gear includes four gears of 5N, 10N, 15N, and 20N, and the driver needs a pedal force of 10N, the driver can slide the pedal force adjustment button to the position corresponding to the 10N gear, and the VCU can use the pedal force value of 10N corresponding to this position as the target pedal force value.

[0049] In addition, in this embodiment, it is also possible not to set a specific pedal force gear, and adopt a non-polarized adjustment method to slowly increase or decrease the pedal force value. For example, assuming that the adjustable range of the pedal force value is 5N-20N, the range is evenly divided into 150 parts, each sliding position corresponds to a pedal force value, a total of 150 pedal force values, so that the pedal force value can be slowly increased or decreased at a speed of 0.1N. During the adjustment process, the specific value of the pedal force value can be displayed in real time on the central control panel, thereby improving the accuracy of control and meeting the pedal force requirements of all drivers.

[0050] In another embodiment, if Figure 3 As shown, the target pedal force value is determined according to the sliding distance of the pedal force adjustment button. Specifically, firstly, based on the sliding end point, the sliding distance of the pedal force adjustment button in the preset area is determined; then, based on the correspondence between the preset distance and the pedal force value, the target pedal force value corresponding to the sliding distance is determined.

[0051] For example: Figure 3 As shown, assuming that the adjustable range of the pedal force value is 5N-20N, and the movable adjustable length of the pedal force adjustment button is 30mm, then the correspondence between the distance and the pedal force value can be predetermined: the pedal force value changes by 0.5N for every 1mm sliding of the pedal force adjustment button. Therefore, in this application, the target pedal force value can be determined according to the sliding distance of the pedal force adjustment button. Assuming that the pedal force adjustment button slides 4mm from the starting point (5N position), the target pedal force value at this time is 5+4×0.5=7N.

[0052] It should be noted that during the above adjustment process, the specific value of the pedal force can be displayed in real time on the central control panel, and the percentage of the sliding distance in the adjustable length can also be displayed.

[0053] Method 2: Determine the target pedal force value based on driving style

[0054] Specifically, monitor whether a second sliding operation occurs in a preset area of ​​the central control panel; wherein the preset area includes a driving style adjustment button, the driving style adjustment button includes multiple preset driving styles, and the second sliding operation is a sliding operation on the driving style adjustment button; if the second sliding operation occurs in the preset area, determine a sliding end point of the second sliding operation, and determine a target driving style corresponding to the sliding end point; based on a predetermined correspondence between the driving style and the pedal force value, determine a target pedal force value corresponding to the target driving style.

[0055] See also Figure 4 As shown, a driving style adjustment button is set on the central control panel, and the driving style adjustment button includes multiple preset driving styles, such as sports style, standard style and comfort style, etc. Each driving style is preset with a corresponding pedal force value stored in the VCU. The driver can select the driving style he wants by sliding the driving style adjustment button. After detecting the driver's second sliding operation on the driving style adjustment button, the VCU can obtain the target driving style selected by the driver, and then obtain the target pedal force value corresponding to the target driving style from the pre-stored correspondence between the driving style and the pedal force value.

[0056] Furthermore, considering that in the prior art, different driving styles correspond to different accelerator pedal characteristics (Pedal map), but the pedal force value is the same, and thus the driver's driving preference may not be satisfied. Therefore, in the embodiment of the present invention, after determining the target driving style corresponding to the sliding end point, the method further includes: sending the target driving style to the power controller, so that the power controller switches to the preset accelerator pedal characteristics corresponding to the target driving style, and sending the preset accelerator pedal characteristics to the central control panel for display.

[0057] In specific implementation, when the driver adjusts the driving style preference on the central control panel, the VCU controls the motor to adjust the pedal force value while transmitting the selected driving style to the power controller. The power controller switches the Pedal map corresponding to the different driving styles that have been preset internally to meet the driver's driving preference and displays the corresponding Pedal map on the central control panel.

[0058] Method 3: Enter the target pedal force value

[0059] Specifically, it is monitored whether an input operation of the target pedal force value occurs in a preset area of ​​the central control panel; if an input operation of the target pedal force value occurs in the preset area, the target pedal force value corresponding to the input operation is obtained.

[0060] See also Figure 5As shown, a button is set on the central control panel, and the driver can directly input the required target pedal force value through the button. After monitoring the driver's input operation of the target pedal force value, the VCU can directly obtain the target pedal force value input by the driver.

[0061] It should be noted that Figures 2 to 5 This is only an example and may be different in actual applications and is not limited here.

[0062] The pedal force adjustment method provided in the embodiment of the present invention adopts electronic control adjustment, and the adjustment is precise and visualized; the pedal force can be adjusted without polarity, and can also be switched and linked with the Pedal map, the adjustment is simple, and human-computer interaction is fully achieved to meet the needs of different customers.

[0063] For ease of understanding, the present invention also provides a specific example of a method for adjusting the pedal force value, see Figure 6 As shown, it mainly includes the following steps S601 to S607:

[0064] Step S601: The driver inputs an adjustment instruction.

[0065] Specifically, the adjustment instruction carries information on changing the pedal force value, and the target pedal force value is determined based on the information. The driver can input the adjustment instruction through the central control panel in any one of the three ways in the aforementioned embodiments.

[0066] Step S602: Send the adjustment instruction to the vehicle controller.

[0067] Step S603: The vehicle controller determines whether the vehicle speed is greater than 0; if so, execute steps S604 to S605; otherwise, execute steps S606 to S607.

[0068] Step S604: The instrument controller reminds the driver that the pedal force can only be adjusted when the vehicle is parked.

[0069] Step S605: The driver stops the vehicle and returns to step S601.

[0070] Step S606: The vehicle controller controls the motor to rotate to adjust the pedal force value, and communicates with the power controller.

[0071] Step S607: The pedal force value and Pedal map adjustment switching is completed.

[0072] Specifically, if the driver uses the method of adjusting the pedal force value according to the driving style, when the driver adjusts the driving style preference on the central control panel, while adjusting the pedal force value through the VCU controlling the motor, the selected driving style can also be transmitted to the power controller, and the power controller switches the Pedal map corresponding to the different driving styles that have been preset internally.

[0073] The pedal force value adjustment method provided in the embodiment of the present invention, firstly, in order to ensure safety, a vehicle speed judgment is added, and the accelerator pedal force is only allowed to be adjusted when the vehicle stops; secondly, by setting the motor speed, the vehicle controller can accurately control the motor rotation angle to achieve accurate changes in the pedal force; at the same time, through calculation, the adjusted pedal force can be displayed on the central control panel to increase the interactive experience; then, in order to improve the accuracy of control, multiple levels of pedal force can be set on the central control panel, and the pedal force adjustment can also be made polarized, that is, it can slowly increase or decrease, so as to meet the pedal force requirements of all customers; finally, the pedal force adjustment and driving style switching linkage can be realized. During power calibration, several Pedal maps are pre-calibrated. While adjusting the pedal force, the Pedal stop vehicle map is switched to meet the driver's driving preference.
