Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and more specifically to an EPB control method, device, vehicle, and storage medium. Background Technology

[0002] Electric vehicles are an inevitable trend in the future development of the automotive industry, and at the same time, electronic parking brakes (EPB) have almost become standard equipment in cars. With the maturity of parking brake technology and its activation from a safety perspective, functions such as automatic EPB clamping when the vehicle is in P gear, automatic EPB clamping after the engine is turned off, and automatic EPB clamping after the door is opened are constantly being developed and widely used.

[0003] With the increasing popularity of electric vehicles, more and more vehicles, especially those from emerging electric vehicle manufacturers, are eliminating the physical EPB switch. The gearshift area only displays the P (Park) gear and other gear buttons, resulting in a more minimalist interior. When the physical EPB switch is removed and a self-clamping function is added after the engine is turned off, the EPB switch cannot be released, thus hindering vehicle maintenance, towing, and other necessary operations. Summary of the Invention

[0004] The purpose of this disclosure is to provide an EPB control method, device, vehicle, and storage medium, which can solve the technical problem in the prior art that the EPB cannot be released after the vehicle is turned off, making it impossible to perform vehicle maintenance, towing, etc.

[0017] In some embodiments, controlling the EPB to clamp or release based on the first determination result and the second determination result includes:

[0018] If the vehicle triggers the automatic clamping when entering the parking gear and the automatic clamping when the engine is turned off, control the EPB to clamp;

[0019] If the vehicle does not trigger the automatic clamping for entering parking gear and the automatic clamping for turning off the engine, control the EPB to release.

[0020] In some embodiments, shifting the vehicle's gear to park or neutral based on the on / off state of the soft switch includes:

[0021] If the soft switch is in an active state, the vehicle's driving gear is shifted into parking gear.

[0022] If the soft switch is in the off state, shift the vehicle's gear into neutral.

[0023] The step of determining whether the vehicle has triggered automatic engagement of parking gear based on the vehicle's current driving gear, and obtaining a first determination result, includes:

[0024] If the vehicle's current driving gear is the parking gear, it is determined that the vehicle has triggered the automatic shift to parking gear.

[0025] If the vehicle's current driving gear is neutral, it is determined that the vehicle will not trigger the automatic shift to parking gear.

[0026] In some embodiments, determining whether the vehicle has triggered the automatic shut-off clamp based on the switching state of the soft switch to obtain a second determination result includes:

[0027] If the soft switch is in an active state, it is determined that the vehicle triggers the engine shutdown self-clamp.

[0028] If the soft switch is in the off state, it is determined that the vehicle will not trigger the engine shutdown self-clamp.

[0029] In some embodiments, the method further includes:

[0030] If the EPB is in the released state, determine the current driving gear of the vehicle;

[0031] If the vehicle's current driving gear is park, the system determines that the vehicle has triggered a self-clamping action in park and controls the EPB to clamp.

When the gear position signal is an IG OFF signal, the system determines whether the vehicle has triggered automatic clamping in parking gear and automatic engine shutdown based on the on / off state of the soft switch. Based on the determination result, the system controls the EPB to clamp or release. This allows the system to control the EPB to clamp or release after the vehicle is turned off, even when the physical EPB switch is disabled but the automatic engine shutdown clamping function is still provided, according to the actual needs of the vehicle. This avoids situations where the vehicle cannot be maintained or towed due to the automatic EPB clamping after the engine is turned off, thus improving the reliability of the vehicle.

[0055] Example 1

[0056] Figure 1 and Figure 2 A flowchart of the EPB control method according to an embodiment of this disclosure is shown, as follows: Figure 1 and Figure 2 As shown, the first embodiment of this disclosure provides an EPB control method, including:

[0057] S101: Determine the on / off status of the soft switch for the EPB automatic shutdown clamping function.

[0058] The EPB control method is applied to the vehicle's controller, which can be the vehicle control unit (VCU) or a separate controller specifically designed to implement the EPB control method.

[0059] A soft switch is a touch switch button set on an in-vehicle touchscreen. The in-vehicle touchscreen can be an in-vehicle control screen or an in-vehicle multimedia screen. The in-vehicle screen can also be a windshield connected to a head-up display, etc.

[0060] In this embodiment, a soft switch for the EPB automatic flameout clamping function (hereinafter referred to as EPB flameout self-clamping function) is preset. The soft switch has two states: active (POWER ON) and closed (POWER OFF). When the soft switch is active, the EPB automatic flameout clamping function is activated; when the soft switch is active, the EPB automatic flameout clamping function is deactivated.

[0061] S102: Obtain the ignition switch position signal of the vehicle.

[0062] The ignition switch position signal includes the ignition switch on signal (IG ON signal) and the ignition switch off signal (IG OFF signal). After receiving the ignition switch position signal, the transmission control unit (TCU) can send it to the controller.

[0063] The IG OFF signal indicates that the ignition switch is off and can be obtained through the vehicle control unit (VCU). Since this embodiment mainly involves the automatic clamping and release of the EPB after the engine is turned off, the IG OFF signal indicating that the vehicle's ignition switch is off is used to determine whether EPB clamping is required.

[0064] S103: When the gear position signal is IG OFF, determine whether the vehicle triggers automatic clamping into parking gear and automatic clamping when the engine is turned off, based on the switching state of the soft switch.

[0065] After the controller receives the ignition switch position signal, it determines whether it is an IG OFF signal. If so, it determines whether the vehicle has triggered the automatic parking and automatic shutdown clamping based on the on / off state of the soft switch for the additional EPB automatic shutdown clamping function.

[0066] Among them, "automatic clamping when entering parking gear" means that when the vehicle is engaged in parking gear (P gear), the EPB is triggered to automatically clamp and park the vehicle; "automatic clamping when turning off the engine" means that when the vehicle is turned off (ignition switch is off), the EPB is triggered to automatically clamp and park the vehicle.

[0067] S104: Control the EPB to clamp or release based on the result of the judgment.

[0068] The system determines whether the vehicle has triggered the automatic clamping function for entering parking gear and automatic clamping function for stopping the engine. Based on the determination result, it controls the EPB to clamp or release. If the automatic clamping function for entering parking gear and automatic clamping function for stopping the engine is triggered, the EPB is controlled to clamp, parking the vehicle. If the automatic clamping function for entering parking gear and automatic clamping function for stopping the engine is not triggered, the EPB is controlled not to clamp. This allows the EPB to be released after the vehicle is turned off, releasing the vehicle from its parking state and allowing it to resume driving, thus enabling vehicle maintenance, towing, etc.

[0069] The EPB control method provided in this embodiment determines the on / off state of the soft switch for the EPB automatic shutdown clamping function and obtains the gear position signal of the vehicle's ignition switch. When the gear position signal is an IG OFF signal, it determines whether the vehicle has triggered automatic clamping in parking gear and automatic shutdown clamping based on the on / off state of the soft switch. Then, it controls the EPB to clamp or release based on the determination result. This method can control the EPB to clamp or release after the vehicle is turned off, even when the physical EPB switch is canceled but the automatic shutdown clamping function is also provided, according to the actual needs of the vehicle. This avoids the vehicle being unable to perform maintenance, towing, or other purposes due to automatic clamping of the EPB after the engine is turned off, thus improving the reliability of the vehicle.

[0070] In addition, in this embodiment, when the gear position signal is an IG OFF signal, the system simultaneously determines whether the vehicle has triggered both the automatic parking engage and automatic parking stop based on the switching state of the soft switch. If both are triggered, the EPB clamps; if neither is triggered, the EPB releases, ensuring the reliability of vehicle parking and driving decisions and guaranteeing user safety. For example, if only the automatic parking stop is triggered and not the automatic parking engage, the EPB can be controlled not to clamp, thus preventing the EPB from suddenly clamping and automatically parking after the vehicle is turned off, which could cause injury to the occupants due to sudden braking and forward tilting.

[0071] In some embodiments, step S103, determining whether the vehicle has triggered automatic engagement of parking gear and automatic shutdown based on the switching state of the soft switch, includes:

[0072] S201: Based on the on / off state of the soft switch, shift the vehicle's gear to parking or neutral.

[0073] S202: Based on the current driving gear of the vehicle, determine whether the vehicle has triggered the automatic clamping into parking gear, and obtain a first determination result;

[0074] S203: Based on the switching state of the soft switch, determine whether the vehicle has triggered the automatic shutdown clamp, and obtain a second determination result.

[0075] In this embodiment, the gear position of the transmission control unit during vehicle operation can be disregarded. The transmission control unit can be directly controlled to engage either Park (P) or Neutral (N) based on the on / off state of the EPB (Engine Brake) automatic shut-off function soft switch. Then, based on the currently engaged driving gear, it is determined whether automatic shut-off is triggered. Simultaneously, the on / off state of the EPB automatic shut-off function soft switch can be used to determine whether the vehicle has triggered automatic shut-off, thus obtaining a second determination result.

[0076] In some embodiments, step S104, controlling the EPB to clamp or release based on the result of the determination, includes:

[0077] S1041: Based on the first judgment result and the second judgment result, control the EPB to clamp or release.

[0078] After obtaining the first judgment result of whether the automatic clamping of the parking gear is triggered and the second judgment result of whether the automatic clamping of the engine shutdown gear is triggered, the first judgment result and the second judgment result can be considered together to determine whether to control the EPB to clamp or release.

[0079] Furthermore, in step S201, according to the on / off state of the soft switch, the vehicle's driving gear is shifted into parking or neutral, including:

[0080] S2011: If the soft switch is in an active state, shift the vehicle's driving gear into parking gear.

[0081] S2012: If the soft switch is in the off state, shift the vehicle into neutral.

[0082] In step S202, based on the vehicle's current driving gear, it is determined whether the vehicle has triggered automatic engagement of parking gear, resulting in a first determination result, including:

[0083] S2021: If the current driving gear of the vehicle is the parking gear, determine that the vehicle triggers the automatic clamping of entering the parking gear;

[0084] S2022: If the current driving gear of the vehicle is neutral, determine that the vehicle does not trigger the automatic clamping of entering parking gear.

[0085] When the soft switch is in the active state, the EPB (Engine Brake) automatic stop function is activated. In this case, the vehicle's gear can be shifted into Park by controlling the transmission control unit. When the transmission control unit shifts into Park, it determines that the automatic stop function needs to be triggered. When the soft switch is in the active state, the EPB automatic stop function is deactivated. In this case, the vehicle's gear can be shifted into Neutral by controlling the transmission control unit, and the automatic stop function will not be triggered.

[0086] P gear, also known as parking gear, is a dedicated parking gear. Therefore, in this embodiment, when the vehicle is engaged in P gear, the automatic parking gear locking mechanism is triggered to ensure that the wheels are mechanically locked when the vehicle is completely stopped, preventing it from rolling. When the vehicle is engaged in N gear, the automatic parking gear locking mechanism is not triggered. This mechanism can be used when starting the vehicle, towing, or temporarily stopping (e.g., at a red light). This facilitates subsequent comprehensive judgment that the vehicle will not trigger the automatic shutdown locking mechanism, and controls the EPB to release, making it convenient for towing when the vehicle is in N gear.

[0087] Furthermore, in step S203, based on the switching state of the soft switch, it is determined whether the vehicle has triggered the automatic engine shutdown clamp, and a second determination result is obtained, including:

[0088] S2031: If the soft switch is in an active state, determine that the vehicle triggers the engine shutdown self-clamp;

[0089] S2032: If the soft switch is in the off state, determine that the vehicle does not trigger the engine shutdown self-clamp.

[0090] In this embodiment, when the soft switch of the EPB flameout self-clamping function is in the on state, it is determined that the flameout self-clamping is triggered; and when the soft switch of the EPB flameout self-clamping function is in the off state, it is determined that the flameout self-clamping is not triggered.

[0091] Furthermore, in step S1041, controlling the EPB to clamp or release based on the first judgment result and the second judgment result includes:

[0092] If the vehicle triggers the automatic clamping when entering the parking gear and the automatic clamping when the engine is turned off, control the EPB to clamp;

[0093] If the vehicle does not trigger the automatic clamping for entering parking gear and the automatic clamping for turning off the engine, control the EPB to release.

[0094] like Figure 2 As shown, when it is determined that both the automatic clamping for entering the parking gear and the automatic clamping for engine shutdown are triggered, the EPB is controlled to clamp after comprehensive judgment. When it is determined that neither the automatic clamping for entering the parking gear nor the automatic clamping for engine shutdown are triggered, the EPB is controlled to release after comprehensive judgment. This allows the EPB to be released when the vehicle is in neutral (N) and the automatic clamping for entering the parking gear is not triggered, facilitating towing; and also prevents the automatic clamping for engine shutdown from being triggered, facilitating vehicle maintenance. During vehicle maintenance, the driver can control the soft switch state of the EPB automatic clamping function by clicking the soft switch button on the vehicle's touchscreen, releasing the EPB. After the EPB is released, the driver can directly enter the maintenance mode by clicking the maintenance mode button on the vehicle's touchscreen to diagnose and repair the vehicle.

[0095] In some embodiments, the method further includes:

[0096] The activation state of the soft switch is determined to be the initial default state of the soft switch.

[0097] In this embodiment, the activation state of the EPB automatic shut-off clamping function soft switch is determined as the initial default state of the soft switch, facilitating the activation of the EPB automatic shut-off clamping function after the engine is shut down in the next ignition cycle. For example, after determining that the soft switch of the EPB automatic shut-off clamping function is in the off state in step S101, and releasing the EPB through steps S103 and S104, the soft switch can be switched from the off state to the on state to promptly activate the EPB automatic shut-off clamping function after the engine is shut down in the next ignition cycle, avoiding any impact on driving safety.

[0098] It is understandable that, in specific implementation, the closed state of the soft switch can also be determined as the initial default state of the soft switch. The determination of the initial default state can be set according to the actual needs of the vehicle, and this disclosure does not specifically limit it.

[0099] In some embodiments, the method further includes:

[0100] S301: If the EPB is in the released state, determine the current driving gear of the vehicle;

[0101] S302: If the current driving gear of the vehicle is the parking gear, determine that the vehicle has triggered the self-clamping of the parking gear, and control the EPB to clamp.

[0102] In the above embodiments, the P and N gears are automatically controlled by the transmission control unit. In this embodiment, the EPB clamping function can be integrated into the vehicle's P gear button. When the EPB is in the released state, the user can press the button to engage the parking gear. When the controller detects that the vehicle has entered the parking gear, it determines to trigger the self-clamping mechanism, thereby controlling the EPB to clamp. This meets the regulatory requirements for the parking brake system while also ensuring user safety.
