[0002] The electronic limited-slip differential (ELSD) is an improved differential used in vehicles. Its operating principle is that when the ELD detects wheel slip, it controls the clutch plate to gradually lock the differential, preventing wheel slip.

[0051] To address the existing problems of limited-slip differentials (ELSDs) having a narrow scope of application and requiring manual operation of a switch to adjust the limited-slip function, the method described in this application is based on a control unit corresponding to the ELD. The method automatically determines the vehicle's power mode and the driver's driving status. When both meet the ELD's operating conditions, the control unit automatically identifies the vehicle's driving mode to activate the corresponding ELD operating mode. This eliminates the need for manual operation and is suitable for racing or sports car scenarios. For example, in the method described in this application, the method for controlling the ELD is suitable for sports car models and is applicable to driving modes such as racing mode and launch mode.

[0052] In the implementation scenario of the method described in this application, the working components include: an electronic limited-slip differential, a control unit corresponding to the electronic limited-slip differential, a high-speed switching solenoid valve, and friction plates. The control unit can control the electronic limited-slip differential to switch operating modes. Specifically, the switching mode is achieved by the control unit controlling the high-speed switching solenoid valve, which in turn controls the friction plates.

[0053] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0054] Embodiment 1: This application discloses a method for controlling an electronic limited slip differential.

[0055] For details, please refer to Figure 1 , a method for controlling an electronic limited slip differential disclosed in this embodiment includes the following steps:

[0056] Step 101: When it is determined that the power mode of the vehicle meets the use conditions of the electronic limited slip differential, the accelerator pedal change rate is calculated.

[0057] In the method described in this embodiment, the power mode of the vehicle includes the acceleration control mode and kinetic energy recovery mode of the vehicle. As an optional method, the control unit corresponding to the electronic limited slip differential can first identify the acceleration control mode of the vehicle. For example, the acceleration control mode of the vehicle may include multiple gears: weak, standard, and strong. After identifying that the driver selects a strong gear in the acceleration mode, the control unit continues to identify the kinetic energy recovery mode of the vehicle. The kinetic energy recovery mode may also include multiple gears: weak, standard, and strong. When identifying that the driver selects a weak gear in the kinetic energy recovery mode, the control unit determines that the power mode of the vehicle meets the use conditions of the electronic limited slip differential.

[0058] As an optional method, the control unit can also simultaneously identify and determine the acceleration control mode and kinetic energy recovery mode of the vehicle. In the embodiment of the present application, the order of identifying the acceleration control mode and kinetic energy recovery mode of the vehicle is not specifically limited.

[0059] When the power mode of the vehicle meets the use condition of the electronic limited slip differential, the control unit calculates the change rate of the accelerator pedal of the vehicle.

[0060] Step 102: Determine whether the vehicle meets the determination conditions of the intense driving state based on the accelerator pedal change rate. If yes, proceed to step 103.

[0061] In an embodiment of the present application, the intense driving state may specifically refer to a state when the accelerator pedal change rate exceeds a change rate threshold. Among them, as an optional method, a accelerator pedal change rate threshold per unit time may be set. When it is detected that the accelerator pedal change rate per unit time exceeds the change rate threshold, it can be determined that the current vehicle is in an intense driving state. The change rate threshold can be set after a comprehensive analysis of the accelerator pedal change rate by collecting the accelerator pedal change rate information of the driver in a normal driving state and combining it with the driver's driving habits collected by the vehicle controller. For example, in actual operation, based on the collected accelerator pedal change rate information and driving habits of the driver, the accelerator pedal change rate threshold per unit time is set to 90%. When it is detected that the accelerator pedal change rate per unit time is 92% during driving, it is determined that the current vehicle is in an intense driving state.

[0062] In the method described in this embodiment, when the control unit corresponding to the electronic limited slip differential recognizes that the accelerator pedal change rate per unit time meets the aggressive driving judgment condition, the control unit determines that the current driving state of the vehicle driver meets the use condition of the electronic limited slip differential.

[0063] Step 103: Activate a corresponding electronic limited slip differential operating mode according to the current driving mode of the vehicle.

[0064] The vehicle has multiple driving modes. In the method of this embodiment, the driving modes specifically include: Economy mode, Standard mode, Sport mode, Track mode, and Launch mode within Track mode. As an optional method, the electronic limited-slip differential is configured to include three operating modes: Off mode, Automatic mode, and Lock mode. These three operating modes are used to match the different driving modes.

[0065] In the method described in this embodiment, as an optional method, the matching strategy between the working mode and the driving mode is as follows:

[0066] When the driving mode is the economy mode, the control unit corresponding to the electronic limited slip differential closes the high-speed switch solenoid valve, that is, turns on the off mode of the electronic limited slip differential to disable the limited slip function and use only the differential function, thereby ensuring the economy of the vehicle during driving.

[0067] When the driving mode is standard mode or sport mode, the control unit correspondingly turns on the automatic mode of the electronic limited slip differential. At this time, the control unit can perform partial compression control on the friction plate according to the slip condition information of the left rear wheel and the right rear wheel of the vehicle to realize the control of the limited slip function, and also supports the driver to input a set value for the friction plate compression force through the smart display setting interface, which can be specifically a duty cycle setting value, and uses the duty cycle control signal corresponding to the duty cycle setting value to adjust the high-speed switching solenoid valve to realize partial compression of the friction plate in the automatic mode. It should be noted that the set value needs to be lower than 80% of the full compression force, that is, the left and right wheels cannot be completely locked in the automatic mode, and only the friction plate compression force lower than 80% can be achieved, so that the wheels can have a differential speed within a certain range to protect vehicle driving safety.

[0068] When the driving mode is Track mode, the control unit activates the locking mode of the electronic limited-slip differential (ELSD). This reduces ineffective power output and ensures vehicle dynamics at high speeds. The control unit can also adjust the friction plate pressure according to the driver's preference. Optionally, when the driving mode is Track mode, a launch mode can be triggered. The control unit sends a locking signal to control the high-speed switch solenoid valve to fully compress the friction plates, fully locking the ELD and ensuring a rigid connection between the left and right rear wheels. This ensures sufficient friction with the ground to provide power during a launch. After the vehicle launches, the ELD automatically releases its full lock when a speed threshold is reached, ensuring safety. The control unit allows the driver to set a speed threshold for unlocking the ELD within a certain range.

[0069] In the method described in this embodiment, as an optional method, the control unit can also control the electronic limited slip differential to be converted into a normal differential when the vehicle is driving normally, so as to provide maximum traction in response to different driving environments and minimize the deflection interference caused to the vehicle.

[0070] The method described in this embodiment automatically activates the limited-slip function when the vehicle's power mode and the driver's driving state meet the operating conditions of the electronic limited-slip differential. The method then activates the corresponding electronic limited-slip differential operating mode based on the vehicle's various driving modes, expanding its applicability beyond off-road scenarios. The method described in this application is entirely computer-based and automatically controlled, eliminating the need for buttons or manual control. This allows for smooth operation of the limited-slip function and supports flexible control of the limited-slip function by driver-entering preset values, significantly improving driving comfort.

[0071] Example 2: This application discloses another method for controlling an electronic limited slip differential, see Figure 2 The method described in this embodiment introduces the automatic mode working process of the electronic limited slip differential.

[0072] Step 201: A control unit corresponding to the electronic limited slip differential identifies the vehicle's driving mode as the standard mode or the sport mode.

[0073] Since the method described in this embodiment is directed to the automatic mode of the electronic limited slip differential, in the method described in this embodiment, as an optional method, the driving mode can be either the standard mode or the sports mode.

[0074] Step 202: The control unit activates the automatic mode of the electronic limited slip differential.

[0075] In the method described in this embodiment, as an optional method, the automatic mode has two specific working methods. If the control unit is required to automatically adjust the clamping control, step 203 can be entered. If a fixed clamping force value needs to be set to adjust the clamping control, step 204 can be entered.

[0076] Step 203: The control unit identifies the slip condition information of the left rear wheel and the right rear wheel of the vehicle, and performs compression control on the friction plate corresponding to the slip condition information.

[0077] In the method described in this embodiment, each wheel is equipped with its own speed sensor. As an optional method, the control unit identifies the slip condition of the vehicle's two rear wheels in real time and controls the friction plate tension accordingly based on the wheel slip condition. For example, in actual operation, the control unit receives vehicle speed information from the speed sensor and identifies that the speed of the left rear wheel exceeds that of the other three wheels within a certain range. In this case, the control unit determines that the left rear wheel is slipping. In this case, the control unit controls the friction plate tension of the left rear wheel to bring its speed closer to that of the other three wheels, thereby alleviating the slip condition.

[0078] In the method described in this embodiment, the range of the clamping control can only be within 80% of the full clamping force. This setting allows a certain range of differential speed to protect vehicle driving safety.

[0079] Step 204: The control unit receives a set value of the pressing force set by the driver.

[0080] In the method described in this embodiment, as an optional method, the set value may be a duty cycle set value, which must be less than 80% of the full pressing force. The control unit uses a duty cycle control signal corresponding to the duty cycle set value to adjust the high-speed switching solenoid valve to achieve partial compression of the friction plate in the automatic mode. The set value can be input through a heads-up display system.

[0081] Step 205: The control unit controls the compression of the friction plate according to the set value.

[0082] The method described in this embodiment targets the automatic mode of an electronic limited-slip differential (ELSD). It automatically identifies the slip conditions of the vehicle's left and right rear wheels and controls the friction plate pressure based on this slip information, achieving automatic identification and control of the limited-slip function. The friction plate pressure can also be adjusted manually by inputting a fixed pressure setting, providing a customizable and highly flexible implementation of the limited-slip function. Furthermore, the setting does not allow for full friction plate pressure, maintaining a certain differential speed between the two wheels. This ensures the flexibility of the limited-slip function while protecting vehicle driving safety.

[0083] Example 3: This application discloses another method for controlling an electronic limited slip differential, see Figure 3 The method described in this embodiment introduces the launch mode workflow of the electronic limited slip differential.

[0084] Step 301: A control unit corresponding to the electronic limited slip differential receives a speed threshold set by a driver.

[0085] In the method described in this embodiment, as an optional method, the set value can be input through a head-up display system.

[0086] Step 302: The control unit recognizes that the driving mode of the vehicle is the ejection mode.

[0087] In the method described in this embodiment, as an optional method, the ejection mode can only be triggered in the track mode, that is, the vehicle can only be identified as the ejection mode when the driving mode is the track mode.

[0088] Step 303: The control unit completely locks the electronic limited slip differential.

[0089] In the method described in this embodiment, as an optional method, the control unit sends a locking signal to control the high-speed switch solenoid valve to fully tighten the friction plate, so that the electronic limited slip differential is fully locked. At this time, the left rear wheel is rigidly connected to the right rear wheel.

[0090] Step 304: The control unit recognizes that the current speed of the vehicle reaches the speed threshold.

[0091] Step 305: The control unit releases the fully locked electronic limited slip differential.

[0092] In the method described in this embodiment, as an optional method, after the electronic limited slip differential is completely locked, the vehicle driving mode is the track mode, and the working mode of the electronic limited slip differential enters the locking mode.

[0093] The method described in this embodiment obtains a set speed threshold. When the vehicle is in track mode, the launch requirement is met by first fully locking the electronic limited slip differential. When the vehicle speed reaches the speed threshold, the electronic limited slip differential is fully unlocked, thereby maintaining friction with the ground during the launch process to provide sufficient power.
