[0052] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only for illustrative purposes and are not used to limit the scope of these messages or information. It is understandable that before using the technical solutions disclosed in the embodiments of the present disclosure, the types, scope of use, usage scenarios, etc. of the personal information involved in the present disclosure should be informed to the user in an appropriate manner in accordance with relevant laws and regulations and the user's authorization should be obtained. The present disclosure is described below in conjunction with specific embodiments.

[0053] First, the application scenario of the present disclosure is explained. Many vehicles are equipped with an Electronic Park Brake (EPB) system. In the case of abnormal ignition or abnormal flameout of the vehicle, if the EPB of the vehicle is in a clamped state, the vehicle cannot move. If it is forced to move, it may cause vehicle failure and corresponding property losses. Among them, ignition abnormality may include: abnormal ignition switch, abnormal ignition circuit, battery abnormality, etc., and abnormal flameout may include: abnormal flameout of the vehicle during driving caused by mechanical failure, circuit failure, and battery failure of the vehicle.

[0054] In order to solve the above problems, better deal with the situation where the vehicle fails to ignite, realize the flameout and towing function of the vehicle in any state, and avoid the situation where the vehicle cannot be repaired, towed, etc. due to the clamping of the EPB after the flameout, the present disclosure provides an EPB control method, which can release the EPB when the vehicle cannot ignite, so as to realize the flameout and towing function of the vehicle.

[0055] Figure 1 FIG. 1 is a flow chart of an EPB control method according to an exemplary embodiment. Figure 1 As shown, the embodiment of the present disclosure provides an EPB control method, the method comprising the following steps:

[0056] In step S11 , it is determined that the EPB of the vehicle is in a clamped state and the EPB controller of the vehicle is in a dormant state.

[0057] Exemplarily, the EPB controller of a vehicle is an electronic control unit (ECU) on the vehicle, which can control the clamping or release of the vehicle's EPB; when the vehicle's ignition switch is in the off position, the vehicle's ECUs usually enter a sleep mode, or enter a sleep mode within a specified time range. Therefore, if the vehicle's EPB is clamped and cannot move due to problems such as abnormal ignition or abnormal flameout, if the vehicle's flameout trailer function needs to be implemented, it is necessary to first determine whether the vehicle's EPB controller is in an awake state. If the EPB controller is in a dormant state, it is necessary to wake up the EPB controller first. For example, before waking up the EPB controller, the vehicle's vehicle control unit (VCU), BCM (Body Control Module) controller, TBOX (Telematics Box, vehicle networking intelligent terminal) and other controllers that can communicate with the EPB controller and the EPB controller can determine the vehicle's EPB state and the state of the EPB controller.

[0058] In step S12, when the EPB switch of the vehicle performs a first designated action, the EPB controller is awakened.

[0059] For example, when it is determined that the EPB of the vehicle is in a clamped state and the EPB controller is in a dormant state, the vehicle user can perform a first designated action through the EPB switch of the vehicle to wake up the EPB controller. The present disclosure does not limit the first designated action. For example, the first designated action can be lifting or pressing the EPB switch, pressing the EPB switch twice in a row, or pressing the EPB switch for 3 seconds.

[0060] In step S13, when the EPB switch performs the second designated action, the EPB is released by controlling the EPB controller.

[0061] Optionally, the second specified action includes any one of the following actions:

[0062] The duration of pressing or lifting the EPB switch is greater than or equal to a third set time;

[0063] The EPB switch is pressed or released continuously for a specified number of times.

[0064] Exemplarily, when the EPB controller is in the awake state, when the user of the vehicle performs the second specified action through the EPB switch, the EPB controller can control the release of the EPB of the vehicle so that the vehicle can be towed. The second specified action can be that the duration of pressing or lifting the EPB switch is greater than or equal to a third set time. The present disclosure does not limit the size of the third set time. For example, the third set time can be 10 seconds. The second specified action can also be that the number of times the EPB switch is continuously pressed or lifted is equal to the specified number of times. The present disclosure does not limit the size of the specified number of times. For example, the specified number of times can be 2 times. It can be understood that the first specified action and the second specified action mentioned above in the present disclosure are different specified actions.

[0065] In the above technical solution, the present disclosure provides an EPB control method, which includes: determining that the EPB of the vehicle is in a clamped state and the EPB controller of the vehicle is in a dormant state; waking up the EPB controller when the EPB switch of the vehicle performs a first specified action; and controlling the EPB to be released by the EPB controller when the EPB switch performs a second specified action. When the vehicle is turned off, the EPB of the vehicle can be released by controlling the EPB switch to achieve the purpose of towing the vehicle, thereby avoiding vehicle failure and property loss caused by towing the vehicle in the clamped state of the EPB.

[0066] Figure 2 FIG. 1 is a flow chart of an EPB control method according to an exemplary embodiment. Figure 2 As shown, step S11 includes the following steps:

[0067] In step S111 , when the ignition switch of the vehicle is in the off position, the EPB is controlled by the EPB controller to clamp.

[0068] For example, when the ignition switch of the vehicle is in the off position, the vehicle is in a parked state. To prevent the vehicle from rolling away, the EPB controller of the vehicle controls the EPB of the vehicle to clamp. During the driving process of the vehicle, the vehicle may be abnormally shut down due to mechanical failure, circuit failure, or other abnormalities, so that the ignition switch of the vehicle is in the off position, and the EPB of the vehicle still needs to be controlled by the EPB controller of the vehicle to clamp. In summary, when the ignition switch of the vehicle is in the off position, the EPB can be controlled by the EPB controller to clamp, which can prevent the vehicle from rolling away.

[0069] In step S112, when the ignition switch of the vehicle is not switched to the on position within the first set time range, the EPB controller of the vehicle is controlled to enter a dormant state.

[0070] For example, a vehicle user may restart the ignition within a short time after the vehicle is abnormally turned off, thereby waking up the EPB controller. In order to avoid frequent switching of the EPB controller state in a short period of time, after the vehicle EPB is clamped, within a first set time range, if the ignition switch of the vehicle is not switched to the on position, the EPB controller of the vehicle can be controlled to enter a dormant state. The present disclosure does not limit the size of the first set time range. For example, the first set time range can be 5 minutes.

[0071] Figure 3 FIG. 1 is a flow chart of an EPB control method according to an exemplary embodiment. Figure 3 As shown, step S13 includes the following steps:

[0072] In step S131, within a second set time range, when the EPB switch performs a second designated action, the EPB is controlled to be released through the EPB controller.

[0073] Exemplarily, after waking up the EPB controller through the first specified action, in order to avoid the EPB controller being in the awake state for a long time, the EPB can be released by controlling the EPB controller within a second set time range after the EPB controller is awakened when the EPB switch performs the second specified action. The present disclosure does not limit the size of the second set time range. For example, the second set time range can be 5 minutes.

[0074] Figure 4 FIG. 1 is a flow chart of an EPB control method according to an exemplary embodiment. Figure 4 As shown, step S13 includes the following steps:

[0075] In step S132, when the EPB switch does not perform the second designated action within the second set time range, the EPB controller is controlled to enter a sleep state.

[0076] Exemplarily, after waking up the EPB controller, if the EPB switch of the vehicle does not perform the second specified action for a long time, the EPB controller may remain in the awake state for a long time, thereby consuming the battery power of the vehicle. In order to avoid wasting the battery power of the vehicle, within the second set time range, if the EPB switch does not perform the second specified action, the EPB controller can be controlled to enter a sleep state.

[0077] Figure 5FIG. 1 is a flow chart of an EPB control method according to an exemplary embodiment. Figure 5 As shown, step S13 includes the following steps:

[0078] In step S133, the BCM controller of the vehicle is awakened.

[0079] For example, the BCM controller (Body Control Module) is an important component in the vehicle's electronic system, which can control the vehicle's doors, windows, rearview mirrors, lights, wipers, etc., and the BCM controller can communicate with other ECUs, and obtain control signals of various components in the vehicle, such as brake signals and gear signal lights, to achieve more complex control and functions. Before the BCM controller obtains the control signal, if the BCM controller is in sleep mode, the BCM controller can be awakened first.

[0080] In step S134, when the EPB switch performs the second designated action and the BCM controller obtains the designated signal, the EPB is controlled to be released through the EPB controller.

[0081] Optionally, the designated signal includes: one or more of a brake signal, a seat belt insertion signal, a gear signal, and a turn signal signal.

[0082] For example, in order to avoid the vehicle from slipping when the ignition switch of the vehicle is in the off position, in order to avoid the user's misoperation or other objects in the vehicle triggering the EPB switch to perform the second specified action, the EPB controller controls the EPB to release, which may cause the vehicle to slip. Therefore, when the EPB switch performs the second action, the vehicle's BCM controller can simultaneously obtain the vehicle's specified controller signal. When the EPB switch performs the second specified action and the BCM controller obtains the specified signal, the EPB controller controls the EPB to release, which can avoid the EPB release caused by the user's misoperation or mistriggered by other objects in the vehicle. The specified signal can include one or more of a brake signal, a seat belt insertion signal, a gear signal, and a turn signal signal.

[0083] For example, when the second designated action is to press the EPB switch for a duration greater than 5 seconds, if the user's water cup happens to be on the EPB switch for a time greater than 5 seconds, the EPB controller will control the EPB to release, which may cause the vehicle to slip. Therefore, in order to avoid false triggering of the second designated action, after waking up the EPB controller, the BCM controller of the vehicle can be woken up, and when the EPB switch performs the second designated action and the BCM controller obtains the designated signal, the EPB can be controlled to release by the EPB controller. Among them, the second designated action can be to press the second switch for a duration greater than 5 seconds, and the designated signal can be a brake signal. It can be understood that when the user of the vehicle steps on the brake, the BCM controller can obtain the brake signal.

[0084] Figure 6 FIG. 1 is a flow chart of an EPB control method according to an exemplary embodiment. Figure 6 As shown, the method also includes the following steps:

[0085] In step S14, when the EPB switch performs a third designated action, the EPB is controlled to be clamped by the EPB controller;

[0086] In step S15, the EPB controller is controlled to enter a sleep state.

[0087] For example, after the vehicle has completed towing, it may still be necessary to park. To prevent the vehicle from slipping, when the EPB switch performs the third designated action, the EPB controller can be controlled to clamp the EPB, and after the EPB is clamped, the EPB controller can be controlled to enter a dormant state. The present disclosure does not limit the third designated action. For example, the third designated action can be pressing the EPB switch twice in a row. In addition, the third designated action can be the same as or different from the first designated action, and the third designated action can be the same as or different from the second designated action.

[0088] In the above technical solution, the present disclosure provides an EPB control method, which includes: determining that the EPB of the vehicle is in a clamped state and the EPB controller of the vehicle is in a dormant state; waking up the EPB controller when the EPB switch of the vehicle performs a first specified action; and controlling the EPB to be released by the EPB controller when the EPB switch performs a second specified action. When the vehicle is turned off, the EPB of the vehicle can be released by controlling the EPB switch to achieve the purpose of towing the vehicle, thereby avoiding vehicle failure and property loss caused by towing the vehicle in the clamped state of the EPB.
