[0032] Figure 1 This is a flowchart of a vehicle parking brake control method according to one embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0033] Step S12: Obtain the target status information of the target vehicle, wherein the target status information includes operating status information and braking component status information.

[0034] In step S12 above, the target status information of the target vehicle can be obtained.

[0035] Specifically, the aforementioned target status information includes operational status information and braking component status information. The operational status information can be a signal indicating whether the target vehicle is in a parked state, which can be denoted as VehicleStandstilSt. For example, when VehicleStandstilSt is 1, it indicates that the target vehicle is in a parked state, and when VehicleStandstilSt is 0, it indicates that the target vehicle is in a non-parked state.

[0036] The above braking component status information refers to the status information of the parking brake, such as the status of the caliper, which can include the following states: Applied, Released, Appling, Releasing, and Unknown.

[0037] Step S14: Determine the target brake button corresponding to the target vehicle based on the operating status information.

[0038] In step S14 above, after obtaining the target status information of the target vehicle, the target brake button corresponding to the target vehicle can be determined based on the running status information in the target status information, and then the target brake button can be used to control the parking brake of the target vehicle.

[0039] Specifically, the aforementioned target braking buttons may include a virtual EPB button, a virtual EPB button for trailer mode, and a physical P-gear button. The virtual EPB button and the virtual EPB button for trailer mode are located on the central control screen of the target vehicle and can be used to apply or release the parking brake in response to user operations.

[0040] Step S16: In response to the triggering operation of the target brake button, control the braking component of the target vehicle to perform the target operation, wherein the target operation includes a clamping operation or a releasing operation.

[0041] In step S16 above, the user can trigger the target brake button by clicking, double-clicking, or long-pressing. When the target brake button is triggered, the brake components of the target vehicle are controlled to perform clamping or releasing operations, thereby enabling the vehicle to apply parking brake or release parking brake.

[0042] It should be noted that the target braking button can be triggered in various ways, not limited to the methods listed above.

[0043] Based on the above steps S12 to S16, by acquiring the target status information of the target vehicle, which includes operating status information and braking component status information, the target brake button corresponding to the target vehicle is determined based on the operating status information. Finally, in response to the triggering operation of the target brake button, the braking component of the target vehicle is controlled to perform the target operation, thereby achieving the purpose of using virtual buttons for parking brake control. This simplifies the parking brake operation and improves vehicle safety, thus solving the technical problem of low vehicle safety caused by inconvenient parking brake operation in related technologies.

[0044] Optionally, in step S14, determining the target braking button corresponding to the target vehicle based on the operating status information includes:

[0045] Step S141: Based on the operating status information, the response determines that the target vehicle is in a normal stopped state and determines that the target brake button corresponding to the target vehicle is the first virtual button, wherein the first virtual button is located in the central control screen of the target vehicle.

[0046] In step S141 above, the normal stop state indicates that the vehicle is in a stopped state and does not require towing. In this state, the target brake button corresponding to the vehicle is determined to be the first virtual button on the central control screen, wherein the first virtual button is the EPB virtual button.

[0047] For example, when the vehicle is in normal parking mode, the vehicle's calipers can be controlled to perform clamping or releasing operations via the EPB virtual button on the central control screen, thereby realizing the vehicle's parking brake or releasing the parking brake.

[0048] By replacing the physical EPB switch with a first virtual button, the static parking brake of the vehicle can be activated or deactivated, thereby simplifying the operation of parking brake control and reducing costs.

[0049] Step S142: Based on the operating status information, the response determines that the target vehicle is in an abnormal stop state, and determines that the target brake button corresponding to the target vehicle is the second virtual button, wherein the second virtual button is located in the central control screen of the target vehicle.

[0050] In step S142 above, the abnormal stop state indicates that the vehicle is in a stopped state and the vehicle needs to be towed. In this state, the target brake button corresponding to the vehicle is determined to be the second virtual button on the central control screen, wherein the second virtual button is the trailer mode EPB virtual button.

[0051] It should be noted that before using the trailer mode EPB virtual button on the central control screen to control the vehicle's calipers to release, the vehicle must be switched to neutral (N) before powering off.

[0052] For example, when the vehicle is in an abnormal parking mode, that is, when the vehicle needs to be towed, the vehicle's calipers can be released by using the towing mode EPB virtual button on the central control screen. This also prevents the calipers from self-clamping when the engine is off and prevents the gear from being shifted to P, thus ensuring that the vehicle is in N gear after power is off and that the calipers are in the released state.

[0053] By replacing the physical EPB switch for trailer mode with a second virtual button, static braking in trailer mode is achieved, thereby simplifying the operation of parking brake control and reducing costs.

[0054] Step S143: Based on the operating status information, the response determines that the target vehicle is in operation and determines that the target brake button corresponding to the target vehicle is a physical button.

[0055] In step S143 above, the above operating state indicates that the vehicle is in a non-stop state. In this case, the target brake button corresponding to the vehicle is determined to be a physical button, wherein the physical button is the P gear physical button.

[0056] Specifically, when the vehicle is not stopped, the user can activate the vehicle's anti-lock braking function through the P gear physical button, so that the vehicle can be controlled to stop slowly with a preset deceleration value (e.g., 0.15g), thereby achieving dynamic braking of the vehicle.

[0057] Based on the above steps S141 to S143, by responding to the determination that the target vehicle is in a normal stopped state based on the operating status information, the target brake button corresponding to the target vehicle is determined to be a first virtual button; by responding to the determination that the target vehicle is in an abnormal stopped state based on the operating status information, the target brake button corresponding to the target vehicle is determined to be a second virtual button; and by responding to the determination that the target vehicle is in a running state based on the operating status information, the target brake button corresponding to the target vehicle is determined to be a physical button, different target brake buttons can be used to realize static parking, dynamic parking, and trailer mode braking of the vehicle when the vehicle is in different operating states.

[0058] Optionally, the vehicle's parking brake control method also includes:

[0059] Step S15: Determine the state and working mode of the first virtual button based on the target state information. The state of the first virtual button includes an enabled state and a disabled state. The working mode of the first virtual button includes activating the parking brake and releasing the parking brake.

[0060] In step S15 above, the state and working mode of the first virtual button can be determined based on the target state information. Specifically, the state and working mode of the first virtual button can be determined based on the operating state information of the target vehicle and the state information of the braking components.

[0061] For example, when the VehicleStandstilSt is 0, it indicates that the vehicle is not stationary. Therefore, the EPB virtual button is disabled and its operating mode is determined to be activating the parking brake. The EPB virtual button's display will be grayed out, indicating that it is unavailable. Since the EPB virtual button is unavailable at this time, it will not respond to user input when the vehicle is not stationary.

[0062] When the VehicleStandstilSt is 1, it indicates that the vehicle is stationary. At this time, it is possible to detect whether there is a fault in the braking components. If there is no fault in the braking components, the state and working mode of the EPB virtual button are determined based on the vehicle braking component status information, which may include the following situations:

[0063] When the vehicle's calipers are in a released or unknown state, the EPB virtual button is confirmed to be enabled, and its operating mode is confirmed to be activating the parking brake. The EPB virtual button is then highlighted to indicate its availability. Because the EPB virtual button is available at this time, the user can press it to engage the calipers and achieve static parking when the vehicle is stationary.

[0064] When the vehicle's calipers are clamped, it is necessary to check whether the brake pedal is depressed. Since the calipers are clamped at this time, if the vehicle is on a slope and the parking brake is released directly via the EPB virtual button without checking whether the brake pedal is depressed, the vehicle may roll backward, which could easily lead to an accident. Therefore, it is necessary to check whether the brake pedal is depressed to ensure vehicle safety.

[0065] When the vehicle's calipers are clamped and the brake pedal is not depressed, the EPB virtual button is disabled and its function is to release the parking brake. The button's display is grayed out, indicating it is unavailable. In this state, clicking the EPB virtual button will have no effect; the vehicle's calipers will not perform any operation.

[0066] When the vehicle's calipers are clamped and the brake pedal is depressed, the EPB virtual button is confirmed to be enabled and its function is to release the parking brake. The EPB virtual button is then highlighted to indicate its availability. The user can then press the EPB virtual button to release the vehicle's calipers, thereby releasing the parking brake.

[0067] When the vehicle's calipers are clamping, the EPB virtual button is determined to be disabled and its operating mode is confirmed to be activating the parking brake. The EPB virtual button is then displayed in gray, indicating it is unavailable. At this time, clicking the EPB virtual button will have no effect; the vehicle's calipers will not perform any operation.

[0068] When the vehicle's calipers are in the release process, the EPB virtual button is determined to be disabled and its operating mode is determined to be releasing the parking brake. The EPB virtual button is then displayed in gray, indicating that it is unavailable. At this time, clicking the EPB virtual button will have no effect; that is, the vehicle's calipers will not perform any operation.

[0069] Based on the above step S15, the state and working mode of the first virtual button can be determined based on the target state information. Then, based on the state and working mode of the first virtual button, parking brake control can be realized through the first virtual button, which simplifies the operation of parking brake control, improves vehicle safety, and reduces costs.

[0070] Optionally, in step S16, in response to the triggering operation of the target brake button, controlling the braking components of the target vehicle to perform the target operation includes:

[0071] Step S161: In response to the first trigger operation of the first virtual button, control the braking component of the target vehicle to perform the target operation based on the state and working mode of the first virtual button.

[0072] In step S161 above, when the user operates the first virtual button, the braking components of the target vehicle can be controlled to perform the target operation based on the state and working mode of the first virtual button.

[0073] For example, when a user presses the EPB virtual button, if the EPB virtual button is grayed out or disabled, and the EPB virtual button is configured to activate or release the parking brake, then the EPB virtual button will not respond to the user's operation.

[0074] When a user presses the EPB virtual button, if the EPB virtual button is highlighted and enabled, and the EPB virtual button is set to activate the parking brake, then the EPB virtual button can control the vehicle's calipers to perform a clamping operation, thereby achieving static parking of the vehicle.

[0075] When a user presses the EPB virtual button, if the EPB virtual button is highlighted and enabled, and the EPB virtual button is set to release the parking brake, then the EPB virtual button can control the vehicle's calipers to perform a release operation, thereby releasing the vehicle's parking brake.

[0076] In an optional embodiment, after a user operates the first virtual button, if the state of the braking component is not detected after a preset time, the user is not allowed to operate the first virtual button again; if the state of the braking component is detected, the user is allowed to operate the first virtual button again.

[0077] In an optional embodiment, when the vehicle is stationary, the user can also apply the static parking brake to the vehicle via the P gear physical button because the P gear and EPB clamping function are linked.

[0078] In an optional embodiment, when the vehicle is stationary, the user can activate the EPB's self-clamp function by turning off the engine, thereby achieving static parking brake on the vehicle.

[0079] In step S162, in response to the second trigger operation of the second virtual button, the braking component of the target vehicle is controlled to perform a release operation.

[0080] In step S162 above, when the user operates the second virtual button, the braking components of the target vehicle can be controlled to perform a release operation.

[0081] Specifically, when the vehicle is in an abnormal parking mode, that is, when the vehicle needs to be towed, the user can use the towing mode EPB virtual button on the central control screen to control the vehicle's calipers to perform a release operation, and prevent the vehicle's calipers from self-clamping when the engine is off, and prevent the gear from being shifted to P, thereby ensuring that the vehicle is in N gear after power is off, and ensuring that the vehicle's calipers are in the released state.

[0082] By replacing the physical EPB switch for trailer mode with a second virtual button, static braking in trailer mode is achieved, thereby simplifying the operation of parking brake control and reducing costs.

[0083] In step S163, in response to the third trigger operation of the physical button, the braking component of the target vehicle is controlled to perform a clamping operation based on the preset deceleration of the target vehicle.

[0084] In step S163 above, when the user operates the physical button, the braking component of the target vehicle can be controlled to perform a clamping operation based on the preset deceleration of the target vehicle, thereby causing the vehicle to stop slowly.

[0085] Specifically, when the vehicle is not stopped, the user can activate the vehicle's anti-lock braking function through the P gear physical button, so that the vehicle can be controlled to stop slowly with a preset deceleration value (e.g., 0.15g), thereby achieving dynamic braking of the vehicle.

[0086] Based on the above steps S161 to S163, by responding to the first trigger operation of the first virtual button, the braking component of the target vehicle is controlled to perform the target operation based on the state and working mode of the first virtual button; by responding to the second trigger operation of the second virtual button, the braking component of the target vehicle is controlled to perform the release operation; and by responding to the third trigger operation of the physical button, the braking component of the target vehicle is controlled to perform the clamping operation based on the deceleration of the target vehicle. It is possible to realize static parking, dynamic parking and trailer mode braking of the vehicle by using different target braking buttons based on the running state of the vehicle and the state and working mode of the braking component.

[0087] Optionally, the vehicle's parking brake control method also includes:

[0088] Step S171: In response to the target vehicle's speed being less than a preset threshold and the target vehicle's first operating status information changing to second operating status information, third operating status information is obtained. The first operating status information is the target vehicle's operating status information obtained at the first moment, and the third operating status information is the target vehicle's operating status information obtained at the second moment. The second moment is after the first moment, and the second moment is spaced apart from the first moment by a preset time interval.

[0089] In step S171 above, there will be speed fluctuations when the vehicle is about to stop, which can easily lead to misjudgment of the vehicle's operating status. Therefore, it is necessary to add conditions for judging the operating status information when the vehicle speed is low.

[0090] For example, when the vehicle speed is less than a preset threshold, such as 1 km / h, a change in the vehicle's operating status information VehicleStandstilSt is detected. For example, when the operating status information VehicleStandstilSt changes from the first operating status information VehicleStandstilSt = 1 to the second operating status information VehicleStandstilSt = 0, the vehicle's operating status information VehicleStandstilSt is re-detected after a preset time interval, such as 1 second, as the third operating status information.

[0091] Step S172: Compare the second running status information and the third running status information to obtain the comparison result.

[0092] In step S172 above, after the third running status information is detected, the second running status information and the third running status information are compared to obtain a comparison result.

[0093] Specifically, the second running status information 1 second ago can be compared with the third running status information 1 second later to determine whether the second running status information and the third running status information are the same.

[0094] Step S173: Adjust the state of the first virtual button based on the comparison result.

[0095] In step S173 above, after obtaining the comparison result, the state of the first virtual button can be adjusted based on the comparison result.

[0096] Specifically, the state of the first virtual button can be adjusted by determining whether the second and third running status information are the same.

[0097] Based on the above steps S171 to S173, in response to the target vehicle's speed being less than a preset threshold and the target vehicle's first operating state information changing to second operating state information, third operating state information is obtained. Then, the second operating state information and the third operating state information are compared to obtain a comparison result. Finally, the state of the first virtual button is adjusted based on the comparison result. This can avoid misjudging the vehicle's operating state when the vehicle is about to stop, thereby ensuring the correct state of the first virtual button and improving vehicle safety.

[0098] Optionally, in step S173, adjusting the state of the first virtual button based on the comparison result includes:

[0099] Step S1731: Based on the comparison result, it is determined that the second running state information and the third running state information are different, and the state of the first virtual button is adjusted based on the first running state information.

[0100] In step S1731 above, when the response determines that the second running state information and the third running state information are different based on the comparison result, the state of the first virtual button can be adjusted based on the first running state information.

[0101] For example, when the vehicle speed is less than 1 km / h, a change in the vehicle's operating status information VehicleStandstilSt is detected. For instance, when the operating status information VehicleStandstilSt changes from the first operating status information VehicleStandstilSt = 1 to the second operating status information VehicleStandstilSt = 0, the vehicle's operating status information VehicleStandstilSt = 1 is detected again after an interval of 1 second as the third operating status information.

[0102] At this time, the third running status information VehicleStandstilSt=1 is different from the second running status information VehicleStandstilSt=0, so the state of the first virtual button is adjusted based on the first running status information VehicleStandstilSt=1.

[0103] In step S1732, the response determines that the second running state information and the third running state information are the same based on the comparison result, and adjusts the state of the first virtual button based on the second running state information.

[0104] In step S1732 above, when the response determines that the second running state information and the third running state information are the same based on the comparison result, the state of the first virtual button can be adjusted based on the second running state information.

[0105] For example, when the vehicle speed is less than 1 km / h, a change in the vehicle's operating status information VehicleStandstilSt is detected. For instance, when the operating status information VehicleStandstilSt changes from the first operating status information VehicleStandstilSt = 1 to the second operating status information VehicleStandstilSt = 0, the vehicle's operating status information VehicleStandstilSt = 0 is detected again after an interval of 1 second and used as the third operating status information.

[0106] At this time, the third running status information VehicleStandstilSt=0 is the same as the second running status information VehicleStandstilSt=0, so the state of the first virtual button is adjusted based on the second running status information VehicleStandstilSt=0.

[0107] Based on the above steps S1731 to S1732, by responding to the comparison result and determining that the second and third operating status information are different, and adjusting the state of the first virtual button based on the first operating status information, and by responding to the comparison result and determining that the second and third operating status information are the same, and adjusting the state of the first virtual button based on the second operating status information, it is possible to avoid misjudging the vehicle's operating status when the vehicle speed fluctuates, thereby ensuring the correct state of the first virtual button and improving vehicle safety.

[0108] Figure 2 This is a schematic diagram of the control logic of a first virtual button according to one embodiment of the present invention, such as... Figure 2 As shown below, the control logic of the first virtual button will be described in detail:

[0109] By detecting the vehicle's operating status information, VehicleStandstilSt, when VehicleStandstilSt = 0, it indicates that the vehicle is not parked. In this case, the first virtual button is inoperable and displays "Activate Parking Brake" in gray; the first virtual button does not respond to user input. When VehicleStandstilSt = 1, it indicates that the vehicle is parked. At this time, it is possible to detect whether there is a fault in the braking components. If there is a fault in the braking components, the first virtual button displays "P!"; if there is no fault in the braking components, the status of the braking components is detected.

[0110] When the braking assembly is in a released or unknown state, the first virtual button is operable and displays "Activate Parking Brake," allowing the user to apply the parking brake. When the braking assembly is clamped, the system checks if the brake pedal is depressed. When the brake pedal is depressed, the first virtual button is operable and displays "Release Parking Brake," allowing the user to release the parking brake. When the brake pedal is not depressed, the first virtual button is inoperable and displays "Release Parking Brake" in gray; it does not respond to user input. When the braking assembly is releasing, the first virtual button is inoperable and displays "Release Parking Brake" in gray; it does not respond to user input. When the braking assembly is clamping, the first virtual button is inoperable and displays "Activate Parking Brake" in gray; it does not respond to user input.

[0111] When a change in the vehicle's operating status information VehicleStandstilSt is detected, the value of VehicleStandstilSt is rechecked after 1 second. If VehicleStandstilSt changes after 1 second, the state of the first virtual button is adjusted according to the VehicleStandstilSt before the change. If VehicleStandstilSt does not change after 1 second, the state of the first virtual button is adjusted according to the VehicleStandstilSt after the change.

[0112] After the user operates the first virtual button, wait 2 seconds. If no feedback status is received from the braking component, the user is not allowed to operate it again. If feedback status is received from the braking component within 2 seconds, the user can operate it again.
