Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a method, apparatus, vehicle, and storage medium for correcting the accelerator pedal MAP gauge of a four-wheel drive vehicle. Background Technology

[0002] Under the four-wheel drive hybrid control platform, the hybrid controller can realize the intelligent distribution of wheel-end torque between the front and rear axles to improve vehicle passability and control the vehicle's attitude. However, the wheel-end torque is greatly affected by the discharge power of the high-voltage battery. When the battery discharge power decreases with the decrease of battery charge, the accelerator pedal will have a free travel when the opening is increased. Therefore, how to avoid the free travel of the accelerator pedal and improve the driver's driving experience is an urgent problem to be solved. Summary of the Invention

[0007] Further, based on the driving information, determining the current accelerator pedal MAP table of the vehicle includes: acquiring the current vehicle speed signal and accelerator pedal opening signal included in the driving information; and determining the current wheel-end torque according to a first mapping table, wherein the first mapping table includes wheel-end torques corresponding to different combinations of vehicle speed signals and accelerator pedal opening signals.

[0008] Furthermore, in the first mapping table, when the vehicle speed signal is constant, the accelerator pedal opening signal is proportional to the wheel end torque.

[0010] Furthermore, when the cell temperature is within the first temperature range and the battery charge decreases from the first charge level to the second charge level, the accelerator pedal MAP correction factor is:

[0011] T = (P1 + P2) / P;

[0012] Where P1 is the discharge power when the battery is at its second charge level, P2 is the engine power, and P is the system maximum power.

[0013] Further, the current accelerator pedal MAP table is corrected according to the current accelerator pedal MAP table and the accelerator pedal MAP table correction coefficient, including: using the product of the current accelerator pedal MAP table and the accelerator pedal MAP table correction coefficient as the corrected accelerator pedal MAP table.

This ensures that the accelerator pedal does not have any free travel, making the accelerator pedal more linear and improving the driving experience.

[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0028] The following is for reference. Figures 1-4 A method, apparatus, vehicle, and storage medium for correcting the accelerator pedal MAP of a four-wheel drive vehicle according to embodiments of the present invention are described.

[0029] Figure 1 This is a flowchart of a method for correcting the accelerator pedal MAP of a four-wheel drive vehicle according to an embodiment of the present invention. Figure 1 As shown, a method for correcting the accelerator pedal MAP gauge of a four-wheel drive vehicle includes the following steps:

[0030] Step S1: Determine that the vehicle is in an accelerating state.

[0031] In practice, the vehicle's acceleration status can be identified by acquiring the accelerator pedal signal. Specifically, the accelerator pedal signal includes the accelerator pedal active position, the accelerator pedal opening value, and the accelerator pedal opening rate of change. When the accelerator pedal active position is active, and both the accelerator pedal opening value and the accelerator pedal opening rate of change are greater than zero, the vehicle is determined to be accelerating.

[0032] Step S2: Obtain vehicle driving information.

[0033] Specifically, the vehicle's driving information includes the vehicle's current speed signal, accelerator pedal opening signal, driving mode signal, and power battery signal. Among them, the speed signal includes the vehicle speed value and the valid speed bit; the driving mode signal includes all-terrain mode, economy mode, comfort mode, power mode, and automatic mode; and the power battery signal includes the battery's charge level and cell temperature signal.

[0034] Step S3: Based on the driving information, determine the vehicle's current accelerator pedal MAP and accelerator pedal MAP correction factor. The accelerator pedal MAP correction factor is determined based on the battery level signal and cell temperature signal included in the driving information.

[0035] Specifically, the total driving power of the vehicle system is greatly affected by the power of the high-voltage battery, and the power of the high-voltage battery pack is greatly affected by the battery charge and cell temperature. Therefore, the accelerator pedal MAP correction coefficient can be determined based on the charge signal and the cell temperature signal, and the accelerator pedal MAP can be corrected after the accelerator pedal MAP correction coefficient is determined.

[0036] Furthermore, the accelerator pedal MAP (Modular Accelerator Panel Parameter) includes the correspondence between vehicle speed and wheel torque under different accelerator pedal opening signals. Different vehicle driving information corresponds to different current accelerator pedal MAPs and accelerator pedal MAP correction coefficients. Therefore, the accelerator pedal MAP and accelerator pedal MAP correction coefficients can be determined based on the vehicle's driving information. For example, when the vehicle speed is 50 km / h and the accelerator pedal opening is 70%, the corresponding wheel torque is 6000 Nm. At this time, the accelerator pedal MAP correction coefficient corresponding to the battery charge and cell temperature signals is 0.5.

[0037] Step S4: Correct the current accelerator pedal MAP table according to the current accelerator pedal MAP table and the accelerator pedal MAP table correction coefficient, and output the corrected accelerator pedal MAP table.

[0038] Specifically, the power of the engine and high-voltage battery is affected by environmental conditions and their own state. In particular, the power of the high-voltage battery pack is greatly affected by the battery charge and cell temperature. When the battery charge decreases, its discharge power also decreases, leading to a decrease in the system's total driving power, i.e., wheel-end torque. At the same vehicle speed and accelerator pedal opening, the accelerator pedal experiences free travel. For example, as... Figure 2 As shown, when the vehicle speed is 0 km / h, the maximum wheel-end torque is 7000 Nm. As the accelerator pedal opening continues to increase, the wheel-end torque remains at 7000 Nm. Therefore, the current accelerator pedal MAP table needs to be corrected based on the current accelerator pedal MAP table and the accelerator pedal MAP table correction factor to ensure that the wheel-end torque in the corrected accelerator pedal MAP table increases with the increase of the accelerator pedal opening, that is, to make the accelerator pedal more linear and improve the driving experience.

[0039] In one embodiment of the present invention, determining the current accelerator pedal MAP table of a vehicle based on driving information includes: acquiring the vehicle's current speed signal and accelerator pedal opening signal included in the driving information; and determining the current wheel-end torque based on a first mapping table, wherein the first mapping table includes wheel-end torques corresponding to different combinations of vehicle speed signals and accelerator pedal opening signals.

[0040] In a specific embodiment, after acquiring the vehicle speed signal and the accelerator pedal opening signal, the current wheel-end torque can be determined by looking up the first mapping table. It should be noted that the current wheel-end torque corresponding to different combinations of vehicle speed signals and accelerator pedal opening signals in the first mapping table is obtained through actual vehicle testing and calibration, which will not be elaborated here.

[0041] In one embodiment of the present invention, in the first mapping table, when the vehicle speed signal is constant, the accelerator pedal opening signal and the accelerator pedal MAP table are proportional.

[0042] In a specific embodiment, the graph of the first mapping table represented by curves is as follows: Figure 3 As shown in the figure, the top curve represents the wheel torque at 100% accelerator pedal opening at different vehicle speeds; the bottom curve represents the wheel torque at close to 0 accelerator pedal opening at different vehicle speeds. The trends of each curve are roughly the same. When the vehicle speed signal is constant, the accelerator pedal opening signal and the wheel torque are directly proportional.

[0043] In one embodiment of the present invention, determining the accelerator pedal MAP correction coefficient based on the power signal and the cell temperature signal includes: determining the accelerator pedal MAP correction coefficient based on a second mapping table, wherein the second mapping table includes accelerator pedal MAP correction coefficients corresponding to different combinations of power signals and cell temperature signals.

[0044] In a specific embodiment, after acquiring the battery charge signal and cell temperature signal, the accelerator pedal MAP correction coefficient is determined by looking up the second mapping table. It should be noted that the accelerator pedal MAP correction coefficients corresponding to different combinations of battery charge signals and cell temperature signals in the second mapping table are obtained through actual vehicle testing and calibration, and will not be elaborated here.

[0045] In one embodiment of the present invention, when the temperature of the battery cell is within a first temperature range and the battery charge decreases from a first charge level to a second charge level, the accelerator pedal MAP correction factor is:

[0046] T = (P1 + P2) / P;

[0047] Where P1 is the discharge power when the battery is at its second charge level, P2 is the engine power, and P is the system maximum power.

[0048] In a specific embodiment, the first temperature range is, for example, 25-45°C, the first charge is, for example, 95%, and the second charge is, for example, 10%. As shown in Table 1, when the battery charge drops from the first charge to the second charge, the battery discharge power decreases from 280kW to 100kW. That is, the discharge power P1 when the battery charge is the second charge is 100kW. The maximum system power P is, for example, 390kW, and the engine power P2 is, for example, 110kW. Thus, the total driving power of the system decreases to about 210kW. Therefore, the accelerator pedal MAP table correction factor is 0.54.

[0051] In one embodiment of the present invention, the current accelerator pedal MAP table is corrected according to the current accelerator pedal MAP table and the accelerator pedal MAP table correction coefficient, including: using the product of the current accelerator pedal MAP table and the accelerator pedal MAP table correction coefficient as the corrected accelerator pedal MAP table.

[0052] Specifically, since the accelerator pedal MAP correction factor is calculated based on the discharge power corresponding to the battery charge, engine power, and system maximum power under different temperature ranges, multiplying the current accelerator pedal MAP by the correction factor results in an accelerator pedal MAP that is proportionally scaled down from the original accelerator pedal MAP. As a result, after changes in battery charge and cell temperature, the wheel-end torque in the corrected accelerator pedal MAP increases with the increase in accelerator pedal opening. There will be no free travel when the accelerator pedal changes from 0 to 100%, making the accelerator pedal more linear and improving the driving experience.

[0053] According to the method for correcting the accelerator pedal MAP of a four-wheel drive vehicle according to an embodiment of the present invention, when the vehicle is in an acceleration state, the current accelerator pedal MAP and the accelerator pedal MAP correction coefficient are determined based on the vehicle's driving information, and the current accelerator pedal MAP is corrected based on the current accelerator pedal MAP and the accelerator pedal MAP correction coefficient, and the corrected accelerator pedal MAP is output. This method can ensure that the accelerator pedal does not have any free travel, making the accelerator pedal more linear and improving the driving experience.
