[0056] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0057] It should be noted that the terms "first", "second", etc. in the present application are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application described here can be implemented in an order different from those illustrated or described here. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0058] With the rapid development of vehicle technology and the continuous improvement of people's living standards, the vehicle ownership is increasing, and new energy vehicles are becoming more and more popular. During the operation of a vehicle, situations where the vehicle needs to be towed due to a breakdown or other reasons often occur. Therefore, the traction mode of the vehicle is essential.

[0059] In the related art, the starting methods of new energy vehicles include starting with a one - key start switch and starting without a one - key start switch. In a vehicle with a one - key start switch as the starting method, the driver can shift to neutral (N gear) and release the handbrake to make the vehicle enter the traction mode.

[0060] However, in a vehicle with a start mode other than a one - touch start switch, when the driver puts the vehicle in neutral and releases the handbrake, as long as the seat belt is released or the door is opened, the automatic shift - to - park (P - gear) function will be triggered. At this time, the electronic handbrake will be automatically pulled up, making the vehicle unable to enter the towing mode and resulting in the vehicle being unable to be towed. Even if there is no automatic shift - to - park function in a vehicle with a non - one - touch start switch, for power protection, if the vehicle is in neutral and the driver leaves the seat for too long, the vehicle will automatically cut off the high - voltage power supply and the electronic handbrake will also be automatically pulled up. Therefore, in a vehicle with a non - one - touch start switch, how to control the vehicle to enter the towing mode is an urgent problem to be solved.

[0061] In a possible implementation, vehicles with a one - touch start switch and vehicles with a non - one - touch start switch are described. For a vehicle with a one - touch start switch, when the driver is in a vehicle power - off state (OFF state), pressing the one - touch start switch (PEPS) button once changes the vehicle's power state from the off state to the accessory state (ACC state), pressing it again changes the state from the accessory state to the on state (ON state), and pressing it one more time returns the power state to the off state. When the driver presses the brake component, regardless of whether the vehicle's power state is the off state, the accessory state, or the on state at this time, as long as the start switch is pressed, the power state will become the on state.

[0062] For a vehicle with a non - one - touch start switch, when the vehicle's power state is in the off state and the driver opens the door, the vehicle's power state changes to the accessory state and the vehicle powers on high voltage. At this time, when the driver presses the brake component, the vehicle's power state changes to the on state. When the driver puts the vehicle in the park gear and opens the door to get out of the vehicle, the vehicle's power state will change to the accessory state, and when locking the vehicle, the power state will change to the off state.

[0063] Figure 1 It is a schematic diagram of the implementation environment of a vehicle towing mode control method provided by an embodiment of the present application, as Figure 1As shown in the figure, the implementation environment includes: a vehicle 101, which includes a Vehicle Control Unit (VCU). The vehicle control unit is the core control unit of a Battery Electric Vehicle (BEV), a Hybrid Electric Vehicle (HEV), a Plug-in Hybrid Electric Vehicle (PHEV), or a connected vehicle, and is responsible for coordinating the operation of various vehicle subsystems (such as the power system, braking system, steering system, battery management system, etc.) to ensure the efficient and safe operation of the vehicle. The vehicle 101 in the embodiments of this application is a battery electric vehicle. The vehicle traction mode control method provided in the embodiments of this application is executed by the vehicle control unit.

[0064] The vehicle control unit can be a terminal device or a server, and the embodiments of this application do not limit this. Optionally, the terminal device can be any electronic device product that can perform human-computer interaction with the user through one or more methods such as a keyboard, touchpad, remote control, voice interaction, or handwriting device. For example, the terminal device can be a smartphone, tablet computer, laptop computer, desktop computer, smart speaker, smart watch, PC (Personal Computer), mobile phone, PDA (Personal Digital Assistant), wearable device, PPC (Pocket PC), smart vehicle head unit, smart TV, etc. The server is a single server, or a server cluster composed of multiple servers, or any one of a cloud computing platform and a virtualization center, and the embodiments of this application do not limit this.

[0065] Optionally, the vehicle 101 further includes an Intelligent Power Brake (IPB), an Electric Vehicle Charging Controller (EVCC), and an Electronic Parking Brake (EPB). Among them, the intelligent integrated braking system is the core braking system of the vehicle, which realizes the coordinated operation of braking energy recovery and mechanical braking through an electronic control unit, supports energy recovery (converting kinetic energy into electrical energy and storing it in the battery), and improves the energy efficiency of the vehicle. The electric vehicle charging communication controller is responsible for managing the communication and charging process between the vehicle and the charging pile, including identifying the connection status of the charging gun, controlling the charging current, voltage, and safety protection. The electronic parking brake system replaces the traditional mechanical handbrake, uses an electric motor to control the rear wheel brake calipers to achieve parking, supports the automatic parking function, improves driving convenience, and is linked with the vehicle controller to automatically release / activate when the vehicle starts or shuts down.

[0066] Those skilled in the art should understand that the above-mentioned terminal devices and servers are only for illustration. Other existing or future terminal devices or servers that are applicable to this application should also be included in the protection scope of this application and are hereby incorporated by reference.

[0067] An embodiment of this application provides a method for controlling a vehicle traction mode. This method can be applied to the above Figure 1 shown implementation environment. Taking Figure 2 the flowchart of a method for controlling a vehicle traction mode provided by an embodiment of this application shown as an example, this method can be executed by the vehicle controller in the vehicle 101 in Figure 1 . As Figure 2 shown, this method includes the following steps 201 to step 203.

[0068] In step 201, when the power state of the vehicle is in the on state, obtain the gear position of the vehicle, the connection status of the charging / discharging gun, and the state of the electronic parking brake system at the current moment.

[0069] In a possible implementation, a vehicle includes a gear sensor, an electric vehicle charging communication controller, and an electronic parking brake system. When the power state of the vehicle is in the on state, the gear sensor sends the gear of the vehicle at the current moment to the vehicle controller, so that the vehicle controller can obtain the gear of the vehicle at the current moment. The electric vehicle charging communication controller sends the connection state of the charging and discharging gun of the vehicle at the current moment to the vehicle controller, so that the vehicle controller can obtain the connection state of the charging and discharging gun of the vehicle at the current moment. The electronic parking brake system sends the state of the electronic parking brake system of the vehicle at the current moment to the vehicle controller, so that the vehicle controller can obtain the state of the electronic parking brake system of the vehicle at the current moment.

[0070] In step 202, when the gear of the vehicle is in the parking gear, the connection state of the charging and discharging gun is not connected, and the state of the electronic parking brake system is available, a first signal is sent to the information display device of the vehicle. The first signal is used to indicate that the traction mode of the vehicle is in an available state, and the first signal is used to indicate that the information display device displays the control corresponding to the traction mode as a touchable state.

[0071] In a possible implementation, after obtaining the gear of the vehicle, the connection state of the charging and discharging gun, and the state of the electronic parking brake system at the current moment in the above step 201, it is necessary to first determine whether the gear of the vehicle is in the parking gear; when the gear of the vehicle is in the parking gear, determine whether the connection state of the charging and discharging gun is not connected; when the connection state of the charging and discharging gun is not connected, determine whether the state of the electronic parking brake system is available; when the state of the electronic parking brake system is available, determine that the traction mode of the vehicle is available; when the traction mode of the vehicle is available, a first signal is sent to the information display device of the vehicle. The first signal is used to indicate that the traction mode of the vehicle is in an available state, the first signal is used to indicate that the information display device displays the control corresponding to the traction mode as a touchable state, and the control corresponding to the traction mode is displayed as a closed state.

[0072] Optionally, displaying the control corresponding to the traction mode as a touchable state may be to display the control corresponding to the traction mode as a first color. The first color is set based on experience or adjusted according to the implementation environment. The embodiments of the present application do not limit this. Exemplarily, the first color is black. As Figure 3 is a schematic diagram of the display of the control corresponding to the traction mode provided by the embodiments of the present application. Figure 3 The control corresponding to the traction mode shown in (1) in is displayed as non-touchable; Figure 3 The control corresponding to the traction mode shown in (2) in is displayed as touchable and in a closed state; Figure 3The control corresponding to the traction mode shown in (3) is displayed in a touchable state and is in an enabled state.

[0073] The information display device can be the central control entertainment screen of the vehicle or other interactive screens in the vehicle. The embodiments of the present application do not limit this. After receiving the first signal, the information display device displays the control corresponding to the traction mode in a touchable state, so that the driver can switch the mode of the vehicle to the traction mode by touching the control corresponding to the traction mode.

[0074] In a possible implementation, when the gear of the vehicle is in neutral, obtain the driving speed of the vehicle at the current moment; determine whether the driving speed of the vehicle is less than the speed threshold; when the driving speed of the vehicle is less than the speed threshold, determine whether the connection state of the charging and discharging gun is not connected; when the connection state of the charging and discharging gun is not connected, determine whether the state of the electronic parking brake system is an available state; when the state of the electronic parking brake system is an available state, determine that the traction mode of the vehicle is available; when the traction mode of the vehicle is available, send a first signal to the information display device of the vehicle.

[0075] Among them, the speed threshold is set based on experience or adjusted according to the implementation environment. The embodiments of the present application do not limit this. Exemplarily, the speed threshold is 2 km / h.

[0076] Optionally, the process of obtaining the driving speed of the vehicle at the current moment includes: obtaining the driving speed of the vehicle at the current moment through interaction with the intelligent integrated braking system. It is also possible that when the power state of the vehicle is in the start state, the intelligent integrated braking system sends the driving speed of the vehicle at the current moment to the vehicle controller, so that the vehicle controller can obtain the driving speed of the vehicle at the current moment.

[0077] As Figure 4 is a flowchart for determining whether the traction mode of the vehicle is available provided by the embodiments of the present application. As Figure 4 shown, this process includes steps 401 to 409. Among them,

[0078] Step 401, when the power state of the vehicle is in the on state, obtain the gear of the vehicle, the connection state of the charging and discharging gun, and the state of the electronic parking brake system at the current moment.

[0079] Step 402, determine whether the gear of the vehicle is in the parking gear.

[0080] When the gear of the vehicle is in the parking gear, execute step 403; when the gear of the vehicle is not in the parking gear, execute step 406.

[0081] Step 403: Determine whether the connection status of the charging and discharging gun is unconnected.

[0082] When the connection status of the charging and discharging gun is unconnected, execute Step 404; when the connection status of the charging and discharging gun is connected, execute Step 409.

[0083] Step 404: Determine whether the status of the electronic parking brake system is available.

[0084] When the status of the electronic parking brake system is available, execute Step 405; when the status of the electronic parking brake system is unavailable, execute Step 409.

[0085] Step 405: Determine that the towing mode of the vehicle is available.

[0086] Step 406: Determine whether the gear of the vehicle is in neutral.

[0087] When the gear of the vehicle is in neutral, execute Step 407; when the gear of the vehicle is not in neutral, execute Step 409.

[0088] Step 407: Obtain the driving speed of the vehicle at the current moment.

[0089] Step 408: Determine whether the driving speed of the vehicle is less than the speed threshold.

[0090] When the driving speed of the vehicle is less than the speed threshold, execute Step 403; when the driving speed of the vehicle is not less than the speed threshold, execute Step 409.

[0091] Step 409: Determine that the towing mode of the vehicle is unavailable.

[0092] In a possible implementation, when the towing mode of the vehicle is available, the vehicle exits the PT Ready state (driving ready state), and at this time, the whole vehicle no longer activates the automatic shift to P (parking gear) function. Among them, the automatic shift to P function means that when the driver unbuckles the seat belt or opens the door in a non-P gear, the vehicle gear will automatically shift to the P gear. That is, when the towing mode of the vehicle is available, when the driver unbuckles the seat belt or opens the door in a non-P gear, the vehicle gear will not automatically shift to the P gear.

[0093] In a possible implementation, after the information display device displays the control for the towing mode as touchable, it may further display a prompt message at the position where the control for the towing mode is located. The prompt message is used to prompt the way to turn on the towing mode. The embodiments of the present application do not limit the position where the control for the towing mode is located. Exemplarily, the position where the control for the towing mode is located is the position next to the control for the towing mode. The embodiments of the present application also do not limit the content of the prompt message. Exemplarily, the prompt message is "To turn on the towing mode, you need to step on the brake. The vehicle may slide after the towing mode is turned on."

[0094] In step 203, when the control for the towing mode is displayed as touchable, in response to receiving a brake operation and a trigger operation on the control for the towing mode, the vehicle is controlled to enter the towing mode.

[0095] In a possible implementation, when the control for the towing mode is displayed as touchable, the driver can control the vehicle to enter the towing mode by touching the control for the towing mode, so that the vehicle can be towed.

[0096] When the driver wants to control the vehicle to enter the towing mode, the driver needs to step on the brake component and trigger the control for the towing mode; in response to receiving a brake operation and a trigger operation on the control for the towing mode, a release request is sent to the electronic parking brake system. The release request is used to release the electronic parking brake system; in the case of receiving a first confirmation message returned by the electronic parking brake system within a first duration, the gear of the vehicle is switched to neutral to make the vehicle enter the towing mode. The first confirmation message is used to indicate that the electronic parking brake system is in a released state.

[0097] Optionally, when the driver steps on the brake component, the vehicle control unit receives the brake operation. When the driver triggers the control for the towing mode, the vehicle control unit receives the trigger operation on the control for the towing mode. After the electronic parking brake system receives the release request, it needs to release the electronic parking brake system within a reference duration and send a first confirmation message to the vehicle control unit after releasing the electronic parking brake system, so that the vehicle control unit knows that the electronic parking brake system has been released.

[0098] Among them, the first duration is set based on experience or adjusted according to the implementation environment. The embodiments of the present application do not limit this. Exemplarily, the first duration is 3 seconds.

[0099] The reason for triggering the control corresponding to the traction mode while stepping on the brake component is to avoid the situation where when the vehicle is temporarily parked on a slope and the user returns to the car, if the user accidentally clicks on the control corresponding to the traction mode due to misoperation, the vehicle starts to roll backward. When the user steps on the brake component and triggers the control corresponding to the traction mode, the situation of vehicle rollback will not occur.

[0100] In a possible implementation manner, when the gear of the vehicle is in neutral, the traction mode of the vehicle is available, and the control corresponding to the traction mode is displayed in a touchable state, in response to receiving a brake operation and a trigger operation for the control corresponding to the traction mode, a release request is sent to the electronic parking brake system, and the release request is used to release the electronic parking brake system; when the first confirmation information returned by the electronic parking brake system is received within the first duration, the vehicle enters the traction mode, and the first confirmation information is used to indicate that the electronic parking brake system is in a released state.

[0101] In a possible implementation manner, after controlling the vehicle to enter the traction mode in response to receiving a brake operation and a trigger operation for the control corresponding to the traction mode, a second signal may also be sent to the information display device, and the second signal is used for the information display device to display the control corresponding to the traction mode in an on state. In this way, after receiving the second signal, the information display device displays the control corresponding to the traction mode it displays in an on state, so that the driver knows that the vehicle is in the traction mode.

[0102] In a possible implementation manner, after controlling the vehicle to enter the traction mode in response to receiving a brake operation and a trigger operation for the control corresponding to the traction mode, the vehicle can also be controlled to exit the traction mode. This process includes: in response to receiving an operation to exit the traction mode, a tightening request is sent to the electronic parking brake system, and the tightening request is used to tighten the electronic parking brake system; when the second confirmation information returned by the electronic parking brake system is received within the second duration, the vehicle is controlled to exit the traction mode. The second confirmation information is used to indicate that the electronic parking brake system is in a tightened state. After receiving the tightening request, the electronic parking brake system tightens the electronic parking brake system.

[0103] The second duration is set based on experience or adjusted according to the implementation environment, and the embodiments of the present application do not limit this. Exemplarily, the second duration is 3 seconds.

[0104] Among them, the operations to trigger the exit from the traction mode include: triggering the operation to exit the traction mode in response to receiving again the triggering operation for the control corresponding to the traction mode; or, triggering the operation to exit the traction mode in response to the vehicle's gear being in the parking gear; or, triggering the operation to exit the traction mode when the connection state of the charging and discharging gun is connected; or, triggering the operation to exit the traction mode when the power state of the vehicle is in a reference state, and the reference state is the off state or the accessory state. The accessory state refers to the state where the vehicle is powered on but the engine is not started.

[0105] In the above implementation, there are multiple ways to make the vehicle exit the traction mode, making the ways for the vehicle to exit the traction mode more diverse and the exit ways of the traction mode more flexible.

[0106] In a possible implementation, when the electronic parking brake system is in a non-released state, control the vehicle to exit the traction mode.

[0107] In a possible implementation, after controlling the vehicle to exit the traction mode, a third signal can also be sent to the information display device, and the third signal is used for the information display device to display the control corresponding to the traction mode as the off state. After receiving the third signal, the information display device displays the control corresponding to the traction mode it displays as the off state, so that the driver knows that the vehicle has exited the traction mode.

[0108] In a possible implementation, when the vehicle is driving on the road, the vehicle's gear is in the D gear (forward gear), and the vehicle's driving speed is 20 km / h. If the driver accidentally touches the control corresponding to the traction mode by mistake, but since the traction mode of the vehicle is unavailable at this time, even if the driver triggers the control corresponding to the traction mode, the vehicle will not enter the traction mode, which can ensure the safety of vehicle driving.

[0109] In a possible implementation, when the vehicle is being charged and the charging pile is on a slope, if the driver accidentally touches the control corresponding to the traction mode by mistake, but since the connection state of the vehicle's charging and discharging gun is connected, the traction mode of the vehicle is unavailable at this time. Therefore, even if the driver touches the control corresponding to the traction mode by mistake, the vehicle will not enter the traction mode, which can ensure the safety of vehicle driving.

[0110] In a possible implementation, when the user is driving the vehicle on the road and the vehicle breaks down and loses power, the user can turn on the traction mode of the vehicle, push the vehicle to a safe place and wait for rescue, and then send the vehicle back to the repair shop for repair by pushing the vehicle onto the rescue vehicle or hooking up the tow hook to let the rescue vehicle tow it.

[0111] In a possible implementation, when the user activates the traction mode on a ramp due to special circumstances and the vehicle starts to roll back, the user can shift the vehicle's gear to the P gear to exit the traction mode, enabling the vehicle to quickly exit the traction mode and thus ensuring the safety of the vehicle's driving.

[0112] In a possible implementation, when the user forgets to exit the traction mode after using it, if the user gets out of the vehicle and locks it, the power state of the vehicle will change to the off state. Since the power state of the vehicle is off, the vehicle will automatically exit the traction mode, thus eliminating the risk of rolling back and making the driving of the vehicle safer.

[0113] For a vehicle without a one-touch start switch, the above method can determine whether the traction mode of the vehicle is available based on the vehicle's gear, the connection status of the charging and discharging gun, and the status of the electronic parking brake system. When the traction mode of the vehicle is available, a first signal is sent to the information display device to make the control corresponding to the traction mode displayed in a touchable state on the information display device, enabling the user to activate the traction mode. The user can control the vehicle to enter the traction mode by stepping on the brake and touching the control corresponding to the traction mode. This method allows a vehicle without a one-touch start switch to also enter the traction mode, and controlling the vehicle to enter the traction mode by triggering the control corresponding to the traction mode makes the way for the vehicle to enter the traction mode more convenient.

[0114] Moreover, through reasonable state judgment and function implementation logic, the risk of the vehicle rolling back is reduced, and the danger of the vehicle accidentally entering the traction mode is also reduced, improving the safety of the vehicle's driving.

[0117] When the vehicle gear is in the park position, the charging and discharging gun is not connected, and the electronic parking brake system is available, the vehicle control unit sends a first signal to the information display device, so that the information display device displays the control corresponding to the traction mode as a touchable state.

[0118] When the vehicle gear is in the neutral position, the vehicle speed is less than the speed threshold, the charging and discharging gun is not connected, and the electronic parking brake system is available, the vehicle control unit sends a first signal to the information display device, so that the information display device displays the control corresponding to the traction mode as a touchable state.

[0119] When a brake operation is received and a trigger operation for the control corresponding to the traction mode is received, the vehicle control unit sends a release request to the electronic parking brake system to release the electronic parking brake system. And send a second signal to the information display device, so that the information display device displays the control corresponding to the traction mode as an enabled state.

[0120] In response to an operation to exit the traction mode, the vehicle control unit sends a tightening request to the electronic parking brake system to tighten the electronic parking brake system. And send a third signal to the information display device, so that the information display device displays the control corresponding to the traction mode as a closed state.

[0127] 6. When the traction mode is available, the vehicle control unit sends a first signal to the information display device, so that the information display device displays the control corresponding to the traction mode as a touchable state.

[0128] 7. In response to receiving a braking operation and a triggering operation for the control corresponding to the traction mode, a release request is sent to the electronic parking brake system.

[0129] 8. The electronic parking brake system enters the release state within a first time period.

[0130] 9. The electronic parking brake system sends a first confirmation message to the vehicle control unit, and the first confirmation message is used to indicate that the electronic parking brake system is in the release state.

[0131] 10. The vehicle control unit switches the gear of the vehicle to the neutral gear, so that the vehicle enters the traction mode.

[0132] 11. The vehicle control unit sends a second signal to the information display device, so that the information display device displays the control corresponding to the traction mode as an open state.
