[0021] Combine the following Figure 1-Figure 4 The invention describes an engine idle speed adjustment method, device, equipment, storage medium and program product.
[0022] Figure 1 It is one of the flow charts of the engine idle speed adjustment method provided by the present invention, such as Figure 1 As shown, the method includes the following: Step 100: determining a first idle speed adjustment mode and a second idle speed adjustment mode based on the running data and operation information of the target vehicle; Specifically, the engine idle speed adjustment method of the present invention provides two engine idle speed adjustment modes: a manual throttle control mode (ie, a first idle speed adjustment mode in the present embodiment) and an idle speed boost control mode (ie, a second idle speed adjustment mode in the present embodiment).
[0023] The judgment condition for the target vehicle to enter the first idle speed adjustment mode or the second idle speed adjustment mode is determined based on the operating data and operation information of the target vehicle, for example, through the speed of the target vehicle, the accelerator pedal position percentage and the operation of the vehicle function buttons.
[0024] Step 200: When the target vehicle enters the first idle speed adjustment mode, the engine idle speed of the target vehicle is adjusted based on the received first idle speed adjustment instruction; Specifically, when the target vehicle meets all the entry conditions of the first idle speed adjustment mode and does not meet any exit condition of the first idle speed adjustment mode, it is determined that the target vehicle enters the first idle speed adjustment mode. When the target vehicle enters the first idle speed adjustment mode, a first idle speed adjustment instruction is generated by operating the target vehicle, and after receiving the first idle speed adjustment instruction, the engine idle speed of the target vehicle is adjusted.
[0025] Step 300: When the target vehicle enters the second idle speed adjustment mode, the engine idle speed of the target vehicle is adjusted based on the received second idle speed adjustment instruction.
[0026] Specifically, when the target vehicle meets all the entry conditions of the second idle speed adjustment mode and does not meet any exit condition of the second idle speed adjustment mode, it is determined that the target vehicle enters the second idle speed adjustment mode. When the target vehicle enters the second idle speed adjustment mode, a second idle speed adjustment instruction is generated by operating the target vehicle, and after receiving the second idle speed adjustment instruction, the engine idle speed of the target vehicle is adjusted.
[0027] This embodiment determines that the vehicle enters the first idle speed adjustment mode and the second idle speed adjustment mode through the running data and operation information of the target vehicle. After entering the first idle speed adjustment mode, the engine idle speed of the target vehicle is adjusted through the received first idle speed adjustment instruction; after entering the second idle speed adjustment mode, the engine idle speed of the target vehicle is adjusted through the received second idle speed adjustment instruction. After entering the idle speed adjustment mode, the engine idle speed of the target vehicle is adjusted through the received idle speed adjustment instruction, so as to cope with the engine idle speed adjustment of the vehicle in various application scenarios.
[0028] In one embodiment, the engine idle speed adjustment method provided by the embodiment of the present invention may further include: Step 110: The speed of the target vehicle is less than or equal to the calibrated speed, the accelerator pedal position percentage is less than or equal to the calibrated percentage, and the cruise control operation is detected as the first idle speed adjustment condition; Step 120: The speed of the target vehicle is greater than the calibrated speed, and a cruise cancel operation and a brake pedal operation are detected as the first idle exit condition; Step 130: When the target vehicle satisfies the first idle speed adjustment condition and does not satisfy the first idle speed exit condition, determine that the target vehicle enters a first idle speed adjustment mode.
[0029] Specifically, the conditions for entering the first idle speed adjustment mode are as follows: 1. The speed of the target vehicle Less than or equal to the set calibrated vehicle speed ; 2. Accelerator pedal position percentage Less than or equal to the set position percentage ; 3. Operate the cruise control buttons (+ and -). The exit conditions of the first idle speed adjustment mode are as follows: 1. Vehicle speed Greater than the set rated speed ; 2. Operate the cruise control off button (off button); 3. Operate the brake pedal (step on the brake pedal).
[0030] The target vehicle enters the first idle speed adjustment mode only when it meets all the entry conditions of the first idle speed adjustment mode and does not meet any of the exit conditions of the first idle speed adjustment mode. The first idle speed adjustment mode is exited when any of the exit conditions are met. When the target vehicle just enters the first idle speed adjustment mode, other conditions are met, and the first idle speed adjustment mode can be entered by using the + and - keys of the cruise button, and the engine idle speed value is the idle speed value before entering the first idle speed adjustment mode.
[0031] In this embodiment, through the first idle speed adjustment mode, the driver can adjust the engine idle speed by multiplexing the cruise button.
[0032] In one embodiment, the engine idle speed adjustment method provided by the embodiment of the present invention may further include: Step 140: The target vehicle speed is less than or equal to the calibrated vehicle speed, the accelerator pedal position percentage is less than or equal to the calibrated percentage, a brake pedal operation is detected for a duration exceeding a first threshold, and a cruise reset operation is detected for a duration exceeding a second threshold as the second idle speed adjustment condition; Step 150: The vehicle speed of the target vehicle is greater than the calibrated vehicle speed, the accelerator pedal position percentage is greater than the calibrated percentage, the brake release operation is detected, and the cruise end operation is detected as the second idle exit condition; Step 160: When the target vehicle satisfies the second idle speed adjustment condition but does not satisfy the second idle speed exit condition, determine that the target vehicle enters a second idle speed adjustment mode.
[0033] Specifically, the conditions for entering the second idle speed adjustment mode are as follows: 1. The speed of the target vehicle Less than or equal to the set rated speed ; 2. Accelerator pedal position percentage Less than or equal to the set throttle position percentage ; 3. The brake pedal is pressed continuously; 4. The cruise reset button is pressed for longer than The exit conditions of the second idle speed adjustment mode are as follows: 1. The speed of the target vehicle Greater than the set rated speed ; 2. Accelerator pedal position percentage Greater than the set throttle position percentage ; 3. Release the brake pedal; 4. Press the cruise off button.
[0034] The target vehicle enters the second idle speed adjustment mode only when it meets all the entry conditions of the second idle speed adjustment mode and does not meet any exit condition of the second idle speed adjustment mode. The target vehicle exits the second idle speed adjustment mode when any exit condition is met.
[0035] In this embodiment, through the second idle speed adjustment mode, the driver can adjust the engine idle speed by multiplexing the cruise button plus or minus.
[0036] Figure 2 FIG. 2 is a flow chart of the engine idle speed adjustment method provided by the present invention. Figure 2 As shown, the method may also include: Step 210: When the target vehicle enters the first idle speed adjustment mode and a cruise reset operation is detected, adjusting the engine idle speed of the target vehicle based on the historically stored idle speed; Step 220: When the target vehicle enters the first idle speed adjustment mode and a cruise reset operation is detected with a duration exceeding a second threshold, the current engine idle speed of the target vehicle is stored in a domain controller; Step 230: When the target vehicle enters the first idle speed adjustment mode and a cruise control operation is detected, adjusting the engine idle speed of the target vehicle based on the cruise control operation; Step 240: When the target vehicle enters the first idle speed adjustment mode and an accelerator pedal operation is detected, the engine idle speed of the target vehicle is adjusted based on the accelerator pedal operation.
[0037] Specifically, when the target vehicle enters the first idle speed adjustment mode, the following operations can be performed: 1. Press the cruise reset button to return to the previously stored engine idle speed value (enter the first idle speed adjustment mode).
[0038] 2. Press and hold the cruise reset button for longer than After that, the current engine idle speed value of the target vehicle can be stored in the domain controller.
[0039] 3. Pressing the + or - key on the cruise control button can adjust the engine idle speed. Pressing the + or - key will increase or decrease the calibrated idle speed. Pressing the + or - key for a certain period of time will increase or decrease the calibrated idle speed in seconds.
[0040] 4. The engine idle speed can also be adjusted by stepping on the accelerator pedal of the target vehicle, and the engine idle speed will not drop after releasing the accelerator pedal.
[0041] There is also an adjustable idle speed range in the first idle speed adjustment mode. The minimum engine idle speed value cannot be less than the first idle speed value of the engine, and the maximum engine idle speed value is greater than the idle speed boost function, but will be within the allowable working idle speed of the engine.
[0042] In this embodiment, when the target vehicle enters the first idle speed adjustment mode, the idle speed of the engine of the target vehicle is adjusted by operating the target vehicle.
[0043] In one embodiment, the engine idle speed adjustment method provided by the embodiment of the present invention may further include: Step 310: When the target vehicle enters the second idle speed adjustment mode and a cruise reset operation is detected, the engine idle speed of the target vehicle is adjusted based on the historically stored idle speed; Step 320: When the target vehicle enters the second idle speed adjustment mode and a cruise reset operation is detected with a duration exceeding a second threshold, the current engine idle speed of the target vehicle is stored in a domain controller; Step 330: When the target vehicle enters the second idle speed adjustment mode and a cruise control operation is detected, the engine idle speed of the target vehicle is adjusted based on the cruise control operation.
[0044] Specifically, the operations that can be performed after entering the second idle speed adjustment mode are as follows: 1. Press the cruise reset button to return to the previously stored engine idle speed value.
[0045] 2. Press and hold the cruise reset button for longer than After that, the current idle speed value of the vehicle can be stored in the domain controller.
[0046] 3. You can adjust the engine idle speed by operating the + or - key of the cruise control. Pressing the + or - key will increase or decrease the calibrated idle speed value. Pressing and holding the + or - key for a certain period of time will increase or decrease the calibrated idle speed value per second.
[0047] In the second idle speed adjustment mode, there is an idle speed adjustment range. The minimum idle speed value cannot be less than the first idle speed value of the engine, and the maximum allowable idle speed value cannot exceed 1000rpm (revolutions per minute). After that, the current idle speed value is stored in the idle speed value of the domain controller, which will be sent to the engine ECU as the continuous idle speed value according to the conditions.
[0048] In this embodiment, when the target vehicle enters the second idle speed adjustment mode, the idle speed of the engine of the target vehicle is adjusted by operating the target vehicle.
[0049] In one embodiment, the engine idle speed adjustment method provided by the embodiment of the present invention may further include: Step 400: When the target vehicle satisfies the first idle exit condition, stop forwarding the first idle adjustment instruction to the engine electronic control unit.
[0050] Specifically, the control strategy of the engine idle speed adjustment method provided by the present invention is as follows: For the first idle speed adjustment mode, after entering this mode, the adjusted idle speed value is sent to the engine ECU through a message, and the engine ECU responds and controls the engine speed to reach the target value. When exiting the first idle speed adjustment mode, the idle speed value of the engine is controlled by the engine itself. Entering the second idle speed adjustment mode, if the adjusted idle speed value is stored in the domain controller, the idle speed value will be used as a continuous idle speed value and continuously sent to the engine ECU according to the conditions. After the target vehicle is powered on and off again, the idle speed value is also continuously sent.
[0051] When the target vehicle is just started and the engine is at rest, the domain controller will set the speed control mode and the set continuous speed value. , sent to the engine ECU through a message. Only when entering the first idle speed adjustment mode or the second idle speed adjustment mode, the adjusted engine speed value is sent, and the idle speed boost function will store the continuous speed value When the target vehicle starts to move, the speed is greater than 0 or the clutch starts to engage, the domain controller will stop sending the speed control mode and speed value and enter other control modes. Only when the clutch is disengaged and the gear is in neutral, the speed control mode and the set continuous speed value will be changed. Sent to the engine ECU. If the gear is not in neutral or the clutch is engaged, the sending stops.
[0052] This embodiment sends the speed control mode and speed value to the engine ECU through the domain controller, thereby changing the engine speed, and also provides static and dynamic control strategies.
