Description

Technical Field

[0001] This application relates to the automotive field, and more particularly to a vehicle power control method, apparatus, electronic device, and readable medium. Background Technology

[0002] During vehicle operation, the driver typically accelerates by pressing the accelerator and decelerates by pressing the brake. To perform certain functions, such as launch control, the driver needs to simultaneously press both the brake and accelerator pedals. In this case, the vehicle will execute the launch control or other functions requiring the simultaneous use of both pedals according to its preset settings.

[0003] In related technologies, users activate pedals according to a prescribed operating procedure to use functions that require both a brake pedal and a power pedal, such as activating the pedals continuously a certain number of times.

[0004] However, the user operation process required to activate the function according to the prescribed procedure is relatively complex, difficult to use, has poor usability, and is not conducive to the vehicle's operating efficiency. Summary of the Invention

[0005] To address the aforementioned technical issues, this application provides a vehicle power control method, device, electronic device, and readable medium, which improves the ease of use of vehicle functions and avoids unexpected actions caused by excessive vehicle power, thereby enhancing vehicle safety, without requiring the user to perform precise control and complex operations to activate the dual-pedal control function.

[0012] If the vehicle speed is less than the vehicle speed threshold and the activation sequence is that the brake pedal is activated before the power pedal, then the power opening is controlled according to the first opening threshold.

[0013] If the vehicle speed is greater than the vehicle speed threshold and the activation sequence is that the power pedal is activated before the brake pedal, then the power pedal opening is controlled according to the second opening threshold, where the second opening threshold is less than the first opening threshold.

[0014] If the vehicle speed and the activation sequence do not meet the conditions for controlling the power opening according to the first opening threshold or the second opening threshold, then the power opening is controlled according to the third opening threshold, wherein the third opening threshold is greater than the second opening threshold and less than the first opening threshold.

[0015] In the embodiments of this application, based on the above technical solution, controlling the power opening degree according to the first opening degree threshold includes:

[0017] If the power opening is less than or equal to the first opening threshold, then the power opening is maintained.

[0018] In the embodiments of this application, based on the above technical solution, if the vehicle speed and the activation sequence do not meet the conditions for controlling the power opening according to the first opening threshold or the second opening threshold, then controlling the power opening according to the third opening threshold includes:

[0019] If both the power pedal and the brake pedal are activated, and the gear shift lever position changes from neutral or parking to forward or reverse; or if the gear shift lever position is not in neutral or parking, the vehicle speed is less than or equal to the vehicle speed threshold, and the power pedal is activated before the brake pedal; or if the gear shift lever position is not in neutral or parking, the vehicle speed is greater than the vehicle speed threshold, and the brake pedal is activated before the power pedal, then the power opening degree is reduced to the fourth opening degree threshold according to a preset slope.

[0020] In the embodiments of this application, based on the above technical solution, after controlling the power opening according to the first opening threshold, the method further includes:

[0021] If the time for controlling the power opening according to the first opening threshold reaches a preset time threshold, or if the vehicle speed is greater than the vehicle speed threshold, or if the position of the gear shift lever changes, then the power opening is reduced to the second opening threshold according to a preset slope.

[0023] If the gear shift lever is not in neutral or parking gear, the power opening is greater than or equal to the fourth power opening threshold, and the braking opening is greater than or equal to the braking opening threshold, then the vehicle is controlled to enter a dual-pedal control state.

[0024] In the embodiments of this application, based on the above technical solution, after adjusting the power opening degree according to the vehicle speed and the activation sequence using a preset opening degree threshold, the method further includes:

[0025] When it is detected that the gear shift lever position has been switched to the parking position, or if the power opening is less than the fourth power opening threshold or if the braking opening is less than the braking opening threshold, the vehicle is controlled to enter the single-pedal control state.

[0026] According to one aspect of the embodiments of this application, a vehicle power control device is provided, comprising:

Then, the corresponding opening threshold is determined according to the vehicle speed and the order in which the two pedals are activated to control the power opening, so that the power output of the dual-pedal function will not exceed the power output of the preset opening. Therefore, without requiring the user to perform precise control and complex operations to activate the dual-pedal control function, the ease of use of the vehicle function is improved, and at the same time, the vehicle power is prevented from being too high and causing unexpected actions, thereby improving the vehicle's safety.

For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0045] The solution presented in this application can be applied to the automotive field, particularly to the launch control process of hybrid electric vehicles or pure electric vehicles with a series-parallel configuration. In these vehicles, the wheel-end power output mechanism is a drive motor when traveling at low speeds. Launch control refers to the driver simultaneously pressing the accelerator and brake pedals, causing the engine to output significant power while the vehicle remains stationary. The driver then releases the brake pedal, allowing the vehicle to instantly gain substantial forward momentum for a rapid start. In this scenario, the solution presented in this application does not require the driver to alter the original launch control procedure. The driver only needs to follow the conventional launch control pedal activation process without any additional operation. The vehicle will then activate the launch control process, and the output power is appropriately limited during the launch to prevent excessive power from causing unexpected actions or insufficient power from failing to achieve the intended purpose.

[0046] Figure 1 A schematic diagram illustrating an exemplary system architecture of the technical solution of this application in an application scenario is shown. Figure 1As shown, the vehicle includes a gear shift lever, an accelerator pedal, and a brake pedal, each connected to corresponding sensors to detect information such as the position of the gear shift lever and the pedal opening. This information is transmitted to the controller, which performs calculations based on the received information and sends control commands to the powertrain module based on the calculation results, thereby adjusting the vehicle's power output. It's understandable that the accelerator pedal controls the vehicle's power output, and it can play different roles in different types of vehicles. For example, it controls the fuel level in a gasoline-powered vehicle and the motor power in an electric vehicle, and its name can vary, such as accelerator pedal or power pedal.

[0047] The technical solution provided in this application will be described in detail below with reference to specific embodiments. Please refer to... Figure 2 , Figure 2 This is a schematic flowchart illustrating a vehicle power control method according to an embodiment of this application. It can be understood that the executing entity of this method can be an on-board controller, control module, or remote computing unit, or other unit used for vehicle control. The following description uses an on-board controller as an example. The vehicle power control method of this application includes the following steps S210 to S230:

[0048] Step S210: Based on the position of the vehicle's gear shift lever, the power pedal's power opening, and the brake pedal's braking opening, control the vehicle to enter a dual-pedal control state.

[0049] Specifically, in this embodiment, the vehicle controller controls the vehicle's state based on the position of the gear shift lever, the power pedal opening, and the brake pedal opening. During normal vehicle use, it operates in a single-pedal control state, meaning that only one of the power pedal or brake pedal is pressed or activated at any given time. When both the power pedal opening and the brake pedal opening reach a certain threshold, the controller determines that both pedals are pressed simultaneously, and the vehicle enters a dual-pedal control state. In this state, the vehicle controller adjusts or limits the power pedal opening based on preset thresholds, thereby adjusting and limiting the vehicle's power. When the vehicle is started and powered on, it defaults to a single-pedal control state. During driving, when the gear shift lever position, power pedal opening, and brake pedal opening meet the conditions for entering the dual-pedal control mode, it enters a dual-pedal control state and controls the vehicle's movement according to the dual-pedal control method.

[0050] Step S220: When the vehicle is in the dual-pedal control state, detect the activation sequence of the power pedal and the brake pedal.

[0051] In this embodiment, when the vehicle is in dual-pedal control mode, the activation sequence of the power pedal and brake pedal is detected. This activation sequence is typically the order in which the power pedal and brake pedal are depressed when entering dual-pedal control mode.

[0052] Step S230: Determine the opening threshold based on the vehicle speed and the activation sequence, and adjust the power opening based on the opening threshold to control the power output of the vehicle.

[0053] In this embodiment, in the dual-pedal control state, the vehicle controller determines the corresponding opening threshold based on the vehicle speed and the different activation sequences of the power pedal and brake pedal. It then uses the determined opening threshold to adjust the power pedal opening, thereby controlling the power output of the vehicle's engine. Specifically, the vehicle's control system stores several preset opening thresholds. The vehicle controller determines the applicable opening threshold for the current state based on the vehicle speed and the pedal depressing sequence, and adjusts the power pedal opening accordingly. In one embodiment, the vehicle controller can also calculate a suitable opening threshold based on the power pedal opening, brake pedal opening, and current vehicle speed, according to a preset formula or conditions.

[0054] In the embodiments of this application, the dual-pedal control state is entered according to the position of the gear shift lever, the status of the power pedal and the brake pedal. Then, the corresponding opening threshold is determined according to the vehicle speed and the order in which the two pedals are activated to control the power opening, so that the power output of the dual-pedal function will not exceed the power output of the preset opening. Therefore, without requiring the user to perform precise control and complex operations to activate the dual-pedal control function, the ease of use of the vehicle function is improved, and at the same time, the vehicle power is prevented from being too high and causing unexpected actions, thereby improving the vehicle's safety.

[0055] In one embodiment of this application, based on the above technical solution, step S230, which determines the opening threshold according to the vehicle speed and the activation sequence, and adjusts the power opening according to the opening threshold to control the power output of the vehicle, specifically includes the following steps:

[0056] If the vehicle speed is less than the vehicle speed threshold and the activation sequence is that the brake pedal is activated before the power pedal, then the power opening is controlled according to the first opening threshold.

[0057] If the vehicle speed is greater than the vehicle speed threshold and the activation sequence is that the power pedal is activated before the brake pedal, then the power pedal opening is controlled according to the second opening threshold, where the second opening threshold is less than the first opening threshold.

[0058] If the vehicle speed and the activation sequence do not meet the conditions for controlling the power opening according to the first opening threshold or the second opening threshold, then the power opening is controlled according to the third opening threshold, wherein the third opening threshold is greater than the second opening threshold and less than the first opening threshold.

[0059] In this embodiment, during the first calculation cycle of entering the dual-pedal control state, the vehicle controller determines three different power control strategies and corresponding opening thresholds based on vehicle speed and different activation sequences. Specifically, the three opening thresholds correspond to three different power opening control strategies, including a strategy of controlling the power opening at a larger value, a strategy of controlling the power opening at a smaller value, and a zero power opening strategy. If the vehicle speed is less than the vehicle speed threshold and the activation sequence is that the brake pedal is activated before the power pedal, the vehicle controller adopts the strategy of controlling the power opening at a larger value and controls the power opening according to the first opening threshold. This strategy indicates that the driver expects to use a launch control method. The first opening threshold is usually set high to ensure that the power output of the vehicle at this power opening can enable the vehicle to have a strong launch control capability and ensure that the temperature of the drive motor and the motor controller during launch control does not exceed the normal design temperature. For example, if the vehicle speed threshold is 5 km / h, the first opening threshold is 50% of the maximum opening. The vehicle's power opening will be increased or directly set to this first opening threshold, thereby increasing the power output of the engine.

[0060] If the vehicle speed exceeds a speed threshold and the activation sequence is accelerator pedal before brake pedal, the vehicle controller employs a zero-power-opening strategy. It then controls the power-opening according to a second threshold, which is less than the first threshold. This strategy indicates that the vehicle is already traveling at a certain speed, and the sequence of pressing the accelerator before the brake indicates the driver's intention to brake. Therefore, the second threshold is typically 0 or close to 0 to reduce engine power output and thus quickly decrease vehicle speed. In this strategy, although the accelerator pedal is depressed, with zero power-opening, only the brake pedal's opening is active, thus braking the vehicle.

[0061] If the vehicle speed and activation sequence do not meet the conditions for controlling the power opening based on the first or second opening threshold, the vehicle controller adopts a strategy of controlling the power opening at a smaller value, and further controls the power opening based on a third opening threshold, where the third opening threshold is greater than the second opening threshold and less than the first opening threshold. In this strategy, the third opening threshold is a smaller value, for example, 20% of the maximum opening. The third opening threshold ensures that the vehicle has a certain power output at this power opening and ensures that the drive motor temperature and motor controller temperature do not exceed the normal design temperature even if the drive motor is stalled for a long time. If the driver's launch start time is too long, this strategy will be switched to prevent the motor from stalling for a long time and the motor controller temperature or motor temperature from becoming too high.

[0062] In this application, the power opening is controlled differently under different conditions, so that in various scenarios where both the power pedal and the brake pedal are pressed, the driver's intention can be accurately identified and the desired vehicle power can be output.

[0063] In one embodiment of this application, based on the above technical solution, the above steps, controlling the power opening according to the first opening threshold, specifically include the following steps:

[0064] If the power opening is greater than the first opening threshold, then the power opening is adjusted to the first opening threshold.

[0065] If the power opening is less than or equal to the first opening threshold, then the power opening is maintained.

[0066] Specifically, in the embodiments of this application, in the strategy of controlling the power opening to a larger value, if the current power opening is greater than the set first power opening threshold, then the power opening is limited to the first power opening threshold; if the current power opening is less than or equal to the first power opening threshold, then the power opening is the current power opening.

[0067] Similarly, in a strategy that controls the power opening to a small value, if the current power opening is greater than the set second power opening threshold, preferably 20%, then the power opening is limited to the set second power opening threshold; if the current power opening is less than or equal to the second power opening threshold, then the power opening is the current power opening.

[0068] In the zero-power opening strategy, when the vehicle speed exceeds the speed threshold, the vehicle control follows the braking priority principle. If the driver then applies the brakes, the vehicle will not output power, and the power opening control will be zero.

[0069] In one embodiment of this application, based on the above technical solution, the step of controlling the power opening according to a third opening threshold if the vehicle speed and the activation sequence do not meet the conditions for controlling the power opening according to the first opening threshold or the second opening threshold includes:

[0070] If both the power pedal and the brake pedal are activated, and the gear shift lever position changes from neutral or parking to forward or reverse; or if the gear shift lever position is not in neutral or parking, the vehicle speed is less than or equal to the vehicle speed threshold, and the power pedal is activated before the brake pedal; or if the gear shift lever position is not in neutral or parking, the vehicle speed is greater than the vehicle speed threshold, and the brake pedal is activated before the power pedal, then the power opening degree is reduced to the fourth opening degree threshold according to a preset slope.

[0071] Specifically, the vehicle enters the strategy of controlling the power opening at a smaller value based on three parallel conditions. The vehicle will enter this strategy if any one of these conditions is met. Specifically, the conditions include: (1) if both the power pedal and the brake pedal are activated and the gear lever position is switched from neutral or parking to forward or reverse; or (2) if the gear lever position is not in neutral or parking, the vehicle speed is less than or equal to the vehicle speed threshold, and the power pedal is activated before the brake pedal; or (3) if the gear lever position is not in neutral or parking, the vehicle speed is greater than the vehicle speed threshold, and the brake pedal is activated before the power pedal. In this case, the vehicle will enter the strategy of controlling the power opening at a smaller value directly from the single-pedal control state, and therefore the power opening will be reduced to the fourth opening according to the preset slope. In specific examples, the above conditions may be, for example: (1) the shift lever is in P / N gear, both the brake pedal and the power pedal are depressed, and the shift lever is switched from P / N to D / R; or (2) the shift lever is not in P / N gear, the vehicle speed is less than or equal to the set vehicle speed threshold, the power pedal is depressed first and then the brake pedal; or (3) for example, the shift lever is not in P / N gear, the vehicle speed is greater than the set vehicle speed threshold, the brake pedal is depressed first and then the power pedal.

[0072] In one embodiment of this application, based on the above technical solution, after controlling the power opening according to the first opening threshold, the method further includes:

[0073] If the time for controlling the power opening according to the first opening threshold reaches a preset time threshold, or if the vehicle speed is greater than the vehicle speed threshold, or if the position of the gear shift lever changes, then the power opening is reduced to the second opening threshold according to a preset slope.

[0074] In this embodiment, after entering the strategy of controlling the power opening at a larger value, the vehicle controller will detect the current state of the vehicle, and if the current state meets certain conditions, it will exit the strategy of controlling the power opening at a larger value. Specifically, exiting the strategy of controlling the power opening at a larger value includes three conditions: (1) if the time for controlling the power opening according to the first opening threshold reaches a preset time threshold, or (2) if the vehicle speed is greater than the vehicle speed threshold, or (3) if the position of the gear shift lever changes, the vehicle will enter the strategy of controlling the power opening at a smaller value, and reduce the power opening to the second opening threshold according to a preset slope. In a specific example, the above conditions may be, for example, if the time in the strategy of controlling the power opening at a larger value exceeds 5 seconds, or if the vehicle speed exceeds the vehicle speed threshold, or if the position of the gear shift lever changes, such as shifting the gear shift lever from D gear to R gear, and from R gear to D gear. At this point, the vehicle switches from a strategy of controlling the power opening at a larger value to a strategy of controlling the power opening at a smaller value. If the power opening is greater than the second throttle opening threshold, the power opening decreases to the second throttle opening threshold according to a certain slope.

[0075] In one embodiment of this application, based on the above technical solution, step S210, which controls the vehicle to enter a dual-pedal control state according to the position of the vehicle's gear shift lever, the power pedal's opening degree, and the brake pedal's braking opening degree, includes the following steps:

[0076] If the gear shift lever is not in neutral or parking gear, the power opening is greater than or equal to the fourth power opening threshold, and the braking opening is greater than or equal to the braking opening threshold, then the vehicle is controlled to enter a dual-pedal control state.

[0077] Specifically, in this embodiment, if the gear shift lever is not in neutral or park, the power opening is greater than or equal to the fourth power opening threshold, and the brake opening is greater than or equal to the brake opening threshold, the vehicle controller will control the vehicle to enter a dual-pedal control state. For example, if the vehicle controller detects that the gear shift lever is not in P / N gear, the current power opening is greater than or equal to the fourth power opening threshold (e.g., 5%), and the brake pedal opening is greater than or equal to the set brake pedal opening threshold (e.g., 3%), then it enters a dual-pedal control state. It can be understood that in a single-pedal control state, if the vehicle is in forward or reverse gear, and both the power and brake pedals are depressed to a certain extent, it can be determined that the driver wants to use a function in the dual-pedal control state, such as launch control, or that the driver has accidentally depressed both pedals simultaneously, requiring the vehicle to make the next control decision in the dual-pedal control state.

[0078] In one embodiment of this application, based on the above technical solution, after step S230, which adjusts the power opening degree according to the vehicle speed and the activation sequence using a preset opening degree threshold, the method further includes:

[0079] When it is detected that the gear shift lever position has been switched to the parking position, or if the power opening is less than the fourth power opening threshold or if the braking opening is less than the braking opening threshold, the vehicle is controlled to enter the single-pedal control state.

[0080] Specifically, in this embodiment, the vehicle controller switches to one-pedal control mode after the vehicle meets certain conditions. Specifically, if the vehicle controller detects that the gear shift lever has been switched to the parking position, or if the power opening is less than the fourth power opening threshold or the brake opening is less than the brake opening threshold, it indicates that the vehicle has completed its start or has abandoned launch control, and the controller will control the vehicle to enter one-pedal control mode. For example, if the vehicle controller detects that the gear shift lever is in Park (P) or the current power opening is less than the fourth power opening threshold or the brake pedal opening is less than the brake pedal opening threshold, it enters one-pedal control mode.

[0081] The overall scheme of this application is illustrated below with specific examples. For clarity, please refer to [link / reference needed]. Figure 3 , Figure 3 This is a schematic flowchart illustrating the control state switching process in an embodiment of this application. Figure 3 As shown, after the vehicle starts, it first enters the single-pedal control state in step 310. Then, the position of the gear shift lever and the status of the accelerator and brake pedals are checked. In step 320, if the gear shift lever is not in P / N position and both the accelerator and brake pedals are depressed, it switches to the dual-pedal control state in step 330, and continues to check the position of the gear shift lever and the status of the accelerator and brake pedals. In the dual-pedal control state, in step 340, if it is detected that the gear shift lever is in P position or the accelerator or brake pedal is released, it returns to the single-pedal control state in step 310.

[0082] In dual-pedal control mode, the vehicle switches between three throttle opening control modes. For details, please refer to [link / reference]. Figure 4 , Figure 4 This is an exemplary flowchart of throttle opening control mode switching in an embodiment of this application. Figure 4As shown, after entering the dual-pedal control state, step 410 checks the gear shift lever, vehicle speed, brake pedal, and accelerator pedal. If the gear shift lever is not in P / N gear, the vehicle speed is less than or equal to the set vehicle speed threshold, and the brake pedal is pressed before the accelerator pedal, then in step 420, the throttle opening control will be in a larger value mode, i.e., launch control mode. Subsequently, in step 430, if the throttle opening control exceeds a certain value in the larger value mode, or the vehicle speed exceeds the set vehicle speed threshold, or the gear shift lever position changes, then in step 440, the throttle opening control will be in a zero value mode. If the conditions in step 410 are not met, then in step 450, if the gear shift lever is not in P / N gear, the vehicle speed exceeds the set vehicle speed threshold, and the accelerator pedal is pressed before the brake pedal, then directly in step 440, the throttle opening control will be in a zero value mode. If the conditions in steps 410 and 450 are not met, then in step 460, the throttle opening control will be in a smaller value mode.

[0083] When switching between single-pedal control and dual-pedal control, and when switching between throttle opening control modes, the on-board controller filters the throttle opening to obtain the throttle opening referenced in the calculation of power output. This ensures smooth power output and prevents abrupt power output when the driving intention changes the mode, thus ensuring vehicle safety.

[0084] In dual-pedal control mode, when switching from a larger throttle opening mode to a smaller throttle opening mode, if the throttle opening is greater than the corresponding throttle opening threshold, the throttle opening will decrease to the throttle opening threshold according to a certain slope.

[0085] When switching from single-pedal control to dual-pedal control, if the throttle opening is greater than the corresponding throttle opening threshold, the throttle opening is directly limited to the threshold to prevent the throttle opening from decreasing too slowly, causing excessive stall torque in the drive motor during launch, and preventing the drive motor or motor controller temperature from exceeding the normal design temperature.

[0086] When transitioning from single-pedal control to dual-pedal control, the throttle opening is controlled at a smaller value. If the throttle opening exceeds a set threshold, it decreases at a certain slope to that threshold. Conversely, when transitioning from single-pedal control to dual-pedal control, the throttle opening is controlled at zero. If the throttle opening is greater than zero, it decreases at a certain slope to zero. This limitation on the throttle opening decrease slope reduces vehicle vibration caused by excessively rapid throttle descent, improving vehicle smoothness.

[0087] When switching from a larger throttle opening mode in dual-pedal control to single-pedal control, the throttle opening ramp rate is not limited, and the throttle opening is directly the original throttle opening. Upon exiting launch control, the vehicle's torque is rapidly output, enhancing acceleration from launch.

[0088] When switching from a lower throttle opening mode in dual-pedal control to single-pedal control, if the initial throttle opening is greater than the corresponding throttle opening threshold, the throttle opening increases according to the set throttle opening ramp. Conversely, when switching from a zero throttle opening mode in dual-pedal control to single-pedal control, if the initial throttle opening is greater than zero, the throttle opening increases according to the set throttle opening ramp. The selection of the throttle opening ramp ensures normal vehicle power output. The vehicle should output power more slowly, unlike the previous method where the throttle opening was zero in dual-pedal control, resulting in no power output and making it difficult for the driver to notice. Releasing the brake to exit dual-pedal control results in a larger power output.
