[0031] Example 1

[0032] Figure 1 A flowchart of a driving mode control method is provided for the first embodiment of the present invention. This embodiment is applicable to the case where the driving mode is switched based on the accelerator pedal opening. The method can be executed by a driving mode control device, which can be implemented in the form of hardware and / or software and can be configured in various general-purpose computing devices. Figure 1 As shown, the method includes:

[0033] S110: Collect the accelerator pedal opening of the vehicle according to a set collection period.

[0034] In this embodiment of the present invention, to identify the vehicle's power demand, the vehicle's accelerator pedal opening is first collected according to a set collection cycle. Specifically, the vehicle control unit (VCU) collects the accelerator pedal's digital signal through an analog-to-digital converter and converts it into an analog signal. For example, the accelerator pedal opening is 40%.

[0035] Since there may be deviations in the accelerator pedal acquisition process, in order to improve the accuracy of power demand identification, the acquired analog signal can be filtered first, and the filtered accelerator pedal opening can be used to identify the power demand.

[0036] S120: Identify the power demand of the vehicle based on the accelerator pedal opening.

[0037] To conserve energy, the vehicle defaults to Eco mode after startup. However, in special driving conditions requiring greater power, such as climbing a hill or overtaking, Eco mode cannot meet the required power. This means the vehicle has an additional power requirement. Failure to adjust the driving mode in a timely manner could result in a traffic accident due to insufficient power. Therefore, it is necessary to identify the vehicle's power requirements at a set interval.

[0038] In an embodiment of the present invention, after collecting the vehicle's accelerator pedal opening, the vehicle's power demand is identified based on the accelerator pedal opening. Specifically, the vehicle's accelerator pedal opening can be compared with a set opening threshold. If the accelerator pedal opening is determined to be greater than the opening threshold, the vehicle's additional power demand is determined to be identified. To prevent false identification, a timer can also be started when the accelerator pedal opening is determined to be greater than the opening threshold. If the accelerator pedal opening remains greater than the opening threshold for a duration exceeding a set time, such as 1000 milliseconds, the vehicle's additional power demand is determined to be identified.

[0039] It can also be set that if a set opening threshold is reached within a set time, it is determined that the vehicle's additional power demand is recognized. For example, if the accelerator pedal opening reaches 60% within 1000 milliseconds, it is determined that the vehicle's additional power demand is recognized.

[0040] In addition, there are some special situations where there is an urgent need for additional power in a short period of time. In this case, the opening change rate of the accelerator pedal can be calculated. When the change rate is greater than the set threshold and the accelerator pedal opening is greater than the opening threshold during the change period, it is determined that the vehicle's additional power demand is recognized.

[0041] S130 : When it is recognized that the vehicle has an additional power demand and the current driving mode of the vehicle is a non-power mode, switch the current driving mode of the vehicle to a power mode.

[0042] In the embodiment of the present invention, after it is recognized that the vehicle has an additional power demand, it is determined whether the current driving mode of the vehicle is the power mode. If not, the current driving mode is switched to the power mode.

[0043] In a specific example, when it is recognized that the vehicle has an additional power demand and the current driving mode of the vehicle is the economic mode, the driving mode of the vehicle is switched from the economic mode to the power mode.

[0044] The technical solution of the embodiment of the present invention collects the accelerator pedal opening of the vehicle according to a set collection cycle, and identifies the power demand of the vehicle based on the accelerator pedal opening. When it is identified that the vehicle has additional power demand and the current driving mode of the vehicle is non-power mode, the current driving mode of the vehicle is switched to power mode. The power demand can be identified based on the state of the driver pressing the accelerator pedal, so that the driving mode is switched according to the power demand without the driver manually switching, which can improve the mode switching efficiency and improve driving safety.

[0045] Example 2

[0046] Figure 2 This is a flowchart of a driving mode control method provided by the second embodiment of the present invention. This embodiment further refines the above embodiment and provides specific steps for identifying the power demand of the vehicle based on the accelerator pedal opening, as well as specific steps after switching the current driving mode of the vehicle to the power mode. Figure 2 As shown, the method includes:

[0047] S210: Collect the accelerator pedal opening of the vehicle according to the set collection period.

[0048] S220: Compare the accelerator pedal opening with a first opening threshold.

[0049] In the embodiment of the present invention, in order to determine whether the vehicle currently has an additional power demand, the accelerator pedal opening is compared with a first opening threshold to determine whether there may be an additional power demand.

[0050] S230: When the accelerator pedal opening is greater than a first opening threshold, start timing using a timer.

[0051] In this embodiment of the present invention, when the accelerator pedal opening exceeds the first opening threshold, it may indicate that the vehicle has an additional power demand that cannot be met in the current mode. However, it may also be a misjudgment caused by a deviation in the accelerator pedal opening data or a driver error. Therefore, when the accelerator pedal opening exceeds the first opening threshold, a timer is started.

[0052] S240: If the duration of the accelerator pedal opening being greater than the first opening threshold exceeds a first time threshold, it is determined that the vehicle has an additional power demand.

[0053] In the embodiment of the present invention, when the accelerator pedal opening is greater than the first opening threshold for a duration exceeding a first time threshold, for example, 1000 milliseconds, it is determined that the vehicle has an additional power demand that cannot be met by the current driving mode.

[0054] S250 : When it is recognized that the vehicle has an additional power demand and the current driving mode of the vehicle is a non-power mode, switch the current driving mode of the vehicle to a power mode.

[0055] S260: When the vehicle is in the power mode, compare the accelerator pedal opening with a first opening threshold.

[0056] In an embodiment of the present invention, when the vehicle is in power mode, the accelerator pedal opening is compared with a first opening threshold to determine the vehicle's subsequent power demand. For example, if the accelerator pedal opening is detected to be less than the first opening threshold, the vehicle's current power demand is determined to be low.

[0057] S270: When the accelerator pedal opening is less than a first opening threshold, switch the vehicle driving mode from the power mode to the economy mode.

[0058] In this embodiment of the present invention, to conserve energy, when the accelerator pedal opening is detected to be less than a first opening threshold, this indicates that the vehicle's current power demand is low. If the vehicle continues to drive in power mode at this point, unnecessary energy waste will result. Therefore, the vehicle can be promptly switched from power mode to economy mode to reduce energy consumption.

[0059] The technical scheme of the embodiment of the present application collects the accelerator pedal opening degree of the vehicle according to a set collection period, compares the accelerator pedal opening degree with a first opening degree threshold value, in the case that the accelerator pedal opening degree is greater than the first opening degree threshold value, starts timing through a timer, in the case that the state duration of the accelerator pedal opening degree being greater than the first opening degree threshold value exceeds a first time threshold value, it is determined that the vehicle has an additional power demand, in the case that the vehicle has an additional power demand and the current drive mode of the vehicle is a non-power mode, the current drive mode of the vehicle is switched to a power mode, in the case that the vehicle is in the power mode, the accelerator pedal opening degree is compared with the first opening degree threshold value, in the case that the accelerator pedal opening degree is less than the first opening degree threshold value, the drive mode of the vehicle is switched from the power mode to an economic mode, through continuous monitoring and comparison of the accelerator pedal opening degree, the misjudgment rate of the power demand can be reduced, and the power demand of the vehicle can be met in time, and in the case of driving in the power mode, the accelerator pedal opening degree is monitored, the economic mode can be switched in time when the power demand is detected to be reduced, and the energy consumption of the vehicle can be reduced.

[0060] Embodiment three

[0061] Figure 3a A flowchart of a drive mode control method provided by the third embodiment of the present application, the embodiment is further refined on the basis of the above-mentioned embodiments, and provides specific steps of identifying the power demand of the vehicle according to the accelerator pedal opening degree, and specific steps after the current drive mode of the vehicle is switched to the power mode. As shown in the figure, Figure 3a The method comprises:

[0062] S310, collecting the accelerator pedal opening degree of the vehicle according to a set collection period.

[0063] S320, calculating the pedal opening degree change rate within a set time period according to the accelerator pedal opening degree.

[0064] In the embodiment of the present application, the vehicle may also have an emergency power demand caused by the need for emergency acceleration, at this time the vehicle controller needs to quickly distinguish the power demand of the vehicle and timely switch the drive mode to meet the power demand.

[0065] In order to be able to identify the above-mentioned emergency power demand, the pedal opening degree change rate within a set time period can be calculated according to the accelerator pedal opening degree, so as to identify the emergency power demand of the vehicle according to the pedal opening degree change rate.

[0066] S330, in the case that the pedal opening degree change rate is greater than a change rate threshold value and the pedal opening degree is greater than a second opening degree threshold value within a set time period, it is determined that the vehicle has an additional power demand.

[0067] In this embodiment of the present invention, when the rate of change of pedal opening exceeds a rate threshold, it may indicate that the vehicle has an emergency power demand. However, this may also be a misjudgment caused by a pedal opening data collection error or driver error. Therefore, it is also necessary to determine whether the pedal opening exceeds a second opening threshold, for example, 60%, within the aforementioned set duration. Only when both the rate of change of pedal opening exceeds the rate threshold and the pedal opening exceeds the second opening threshold within the set duration is the vehicle confirmed to have an additional power demand. This significantly reduces misjudgments while ensuring rapid identification of power demand.

[0068] S340: When it is recognized that the vehicle has an additional power demand and the current driving mode of the vehicle is a non-power mode, switch the current driving mode of the vehicle to a power mode.

[0069] S350: Using the accelerator pedal opening as the horizontal coordinate and the torque request coefficient as the vertical coordinate, establish pedal mapping diagrams for the economy mode and the sport mode, respectively.

[0070] In the embodiment of the present invention, Figure 3b As shown in the figure, the accelerator pedal opening is used as the horizontal coordinate and the torque request coefficient is used as the vertical coordinate to establish the pedal mapping diagrams for the vehicle in the economy mode and the sport mode respectively. According to the pedal mapping diagram, the torque request coefficient can be determined according to the current accelerator pedal opening of the vehicle. Figure 3b It can be determined that under the same pedal opening, the power mode has higher power output than the economic mode.

[0071] S360: Based on the pedal map, the accelerator pedal opening, and the current driving mode of the vehicle, determine the actual requested torque and send it to the motor controller.

[0072] In an embodiment of the present invention, after establishing a pedal map, a corresponding pedal map can be determined based on the vehicle's current driving mode. Furthermore, within the corresponding pedal map, the actual requested torque is determined based on the accelerator pedal opening and sent to the motor controller.

[0073] Optionally, based on a pedal map, an accelerator pedal opening, and a current driving mode of the vehicle, determining an actual requested torque to send to a motor controller includes:

[0074] determining, based on a current driving mode of the vehicle, a target pedal map corresponding to the current driving mode;

[0075] determining a torque request coefficient corresponding to the accelerator pedal opening in the target pedal map based on the accelerator pedal opening;

[0076] Based on the available peak torque of the electric machine and the torque request coefficient, an actual requested torque is determined and sent to the electric machine controller.

[0077] This optional embodiment provides a specific method for determining the actual requested torque to be sent to the motor controller based on the pedal map, accelerator pedal position, and the vehicle's current drive mode. The method first obtains the vehicle's current drive mode and then determines a target pedal map corresponding to the current drive mode. For example, if the current drive mode is power mode, the pedal map for power mode is used as the target pedal map.

[0078] Furthermore, based on the vehicle's current accelerator pedal position, the target pedal map determines the torque request coefficient corresponding to that position in the current drive mode. Finally, the motor's available peak torque is multiplied by the torque request coefficient to generate the actual requested torque, which is then sent to the motor controller for vehicle motion control. By establishing pedal maps for different drive modes, differentiated power output calibration is achieved for each drive mode, enabling rapid determination of the actual requested torque and transmission to the motor controller for precise torque control.

[0079] The technical solution of the embodiment of the present invention collects the accelerator pedal opening of the vehicle according to a set collection cycle, calculates the pedal opening change rate within a set time period based on the accelerator pedal opening, and when the pedal opening change rate is greater than the change rate threshold and the pedal opening is greater than a second opening threshold within the set time period, it is determined that the vehicle has additional power demand, which can achieve fast and accurate power demand identification, and uses the accelerator pedal opening as the horizontal coordinate and the torque request coefficient as the vertical coordinate to establish pedal mapping diagrams in economic mode and sports mode respectively. Based on the pedal mapping diagram, the accelerator pedal opening and the current driving mode of the vehicle, the actual requested torque is determined and sent to the motor controller. The actual requested torque can be quickly determined and sent to the motor controller to achieve accurate torque control.
