Description

Technical Field

[0001] This invention relates to the field of vehicle fragrance control technology, and in particular to a control method, system and vehicle for delaying the power-off of a vehicle fragrance system. Background Technology

[0002] As people pay more attention to the air quality inside vehicles, in-car fragrances are increasingly being used. The scents released by in-car fragrances can improve the driver's mood and refresh their mind, thus providing a comfortable driving environment while enhancing driving safety.

[0003] However, in existing technologies, if the car air freshener is powered by the ignition switch, the power supply is cut off when the vehicle is turned off. This means the air freshener isn't promptly turned off, reducing its lifespan. If it's powered by the battery, the battery continuously supplies power, consuming battery power and shortening its lifespan. Therefore, reducing the cost of using car air fresheners and extending battery life are pressing issues that need to be addressed. Summary of the Invention

[0004] This invention provides a control method, system, and vehicle for delaying the power-off of in-vehicle fragrance diffusers, which can solve the problems of high usage costs and short battery life of in-vehicle fragrance diffusers.

[0005] According to one aspect of the present invention, a method for controlling delayed power-off of an in-vehicle fragrance diffuser is provided, comprising:

[0006] When the target vehicle switches from running state to engine off state, the ignition switch power-off signal is sent from the target body controller to the target engine control unit.

[0007] The target engine control unit receives the ignition switch power-off signal and controls the target engine to enter the off state. It counts the target time for the target engine to be in the off state. When the target time reaches the preset delay, it sends a disconnect command to the target main relay switch to control the target vehicle fragrance to delay power-off.

[0008] According to another aspect of the present invention, a control system for delayed power-off of an in-vehicle fragrance diffuser is provided, comprising:

[0009] The target vehicle body controller is used to send an ignition switch power-off signal to the target engine control unit when the target vehicle switches from running state to engine off state.

[0010] The target engine control unit is used to receive the ignition switch down signal and control the target engine to enter the shutdown state, and to time the target duration of the target engine in the shutdown state. When the target duration reaches the preset delay, it sends a disconnect command to the target main relay switch.

[0011] The target main relay switch is used to receive disconnection commands from the target engine control unit in order to control the delayed power-off of the target vehicle fragrance system.

[0012] According to another aspect of the present invention, a vehicle is provided, the vehicle comprising:

[0013] The system includes a body controller, an engine control unit, a main relay switch, a vehicle fragrance system, at least one processor, and a memory communicatively connected to the at least one processor; wherein...

[0014] The memory stores a computer program that can be executed by the at least one processor, which enables the at least one processor to perform the vehicle fragrance delayed power-off control method according to any embodiment of the present invention.

[0015] The technical solution of this invention involves the target vehicle controller sending an ignition switch power-off signal to the target engine control unit when the target vehicle switches from running to off state. The target engine control unit then receives the ignition switch power-off signal and controls the target engine to enter the off state. A target duration for which the target engine remains off is timed is recorded. When the target duration reaches a preset delay, a disconnect command is sent to the target main relay switch to control the delayed power-off of the target in-vehicle air freshener. This solves the problems of high operating costs and low battery lifespan of in-vehicle air fresheners in the prior art, reducing the operating cost of in-vehicle air fresheners and increasing battery lifespan.

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0024] It should be noted that the terms "target," "initial," "preset," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0025] Example 1

[0026] Figure 1 This is a flowchart of a control method for delayed power-off of a car air freshener according to Embodiment 1 of the present invention. This embodiment is applicable to situations where the car air freshener is turned off after the vehicle is turned off. This method can be executed by a control system for delayed power-off of the car air freshener. This control system can be implemented in hardware and / or software and can be configured in the vehicle. Figure 1 As shown, the method includes:

[0027] S110. When the target vehicle switches from running state to off state, the ignition switch is sent to the target engine control unit through the target body controller.

[0028] Here, "target vehicle" can refer to a vehicle that requires a delayed power-off function for its in-vehicle fragrance system. "Body Control Module (BCM)" can refer to a module that discretely controls numerous components within a vehicle. "Target Body Control Module" can refer to the body control module corresponding to the target vehicle. "Engine Management System (EMS)" can refer to a gasoline engine management system that integrates fuel injection, ignition timing, and emission control, primarily consisting of controllers, sensors, and actuators. "Target Engine Control System" can refer to the engine control system corresponding to the target vehicle. "Ignition switch power-off signal" can refer to the signal indicating that the ignition switch is in the off state. For example, it could be an ignition switch power-off (IG off) signal.

[0029] In an optional implementation, before sending the ignition switch power-off signal to the target engine control unit through the target body controller, the method further includes: determining a preset time delay based on the closing time of the target vehicle fragrance completing the closing action.

[0030] The target car fragrance can refer to the car fragrance corresponding to the target vehicle. The off time can refer to the time consumed by the target car fragrance to perform the off action. Typically, different target car fragrances have different off times, and this embodiment of the invention does not impose any limitations on this. The preset delay can refer to a pre-set delay duration. For example, the off time can be used as the preset delay, or the duration exceeding the set threshold for the off time can be used as the preset delay. That is, the preset delay needs to be a time value equal to or greater than the off time.

[0031] Therefore, by determining the preset delay based on the closing time of the target car fragrance, an effective basis can be provided for subsequent operations.

[0032] It is worth noting that, in the embodiments of the present invention, the target engine control unit can be connected to the target body controller via a controller area network (CAN) or via a hard wire to receive the ignition switch power-down signal. The embodiments of the present invention do not impose any restrictions on this.

[0033] S120: Receive the ignition switch power-off signal through the target engine control unit and control the target engine to enter the off state. Time the target engine in the off state for a target duration. When the target duration reaches the preset delay, send a disconnect command to the target main relay switch to control the target vehicle fragrance to delay power-off.

[0034] The target engine can refer to the engine of the target vehicle. Typically, after the ignition switch is triggered and turned off, the target body controller receives the ignition switch power-off signal for the target vehicle and sends this signal to the target engine control unit. This allows the target engine control unit to recognize that the target vehicle has a shutdown request and then controls the target engine to switch from the running state to the shutdown state, thus shutting down the target vehicle.

[0035] The target duration refers to the length of time the target engine is in a switched-off state. The main relay switch refers to a switch with functions such as automatic adjustment, safety protection, and circuit switching. The target main relay switch refers to the main relay switch corresponding to the target vehicle. The disconnect command refers to the command to disconnect the target main relay switch. This disconnects the battery's power supply to the target vehicle's air freshener.

[0036] The technical solution of this invention involves the target vehicle controller sending an ignition switch power-off signal to the target engine control unit when the target vehicle switches from running to off state. The target engine control unit then receives the ignition switch power-off signal and controls the target engine to enter the off state. A target duration for which the target engine remains off is timed is recorded. When the target duration reaches a preset delay, a disconnect command is sent to the target main relay switch to control the delayed power-off of the target in-vehicle air freshener. This solves the problems of high operating costs and low battery lifespan of in-vehicle air fresheners in the prior art, reducing the operating cost of in-vehicle air fresheners and increasing battery lifespan.

[0037] Example 2

[0038] Figure 2 This is a flowchart of a method for delaying the power-off of a vehicle fragrance diffuser according to Embodiment 2 of the present invention. This embodiment is a refinement based on the above embodiment. Specifically, this embodiment refines the operation of receiving the ignition switch power-off signal from the target engine control unit, controlling the target engine to enter the off state, and timing the target duration of the target engine in the off state. Specifically, it may include: receiving the ignition switch power-off signal from the target engine control unit, controlling the target engine to switch from the running state to the off state, and recording the initial switching time of the target engine to the off state; and timing the duration of the target engine in the off state based on the initial switching time to obtain the target duration. Figure 2 As shown, the method includes:

[0039] S210. When the target vehicle switches from running state to off state, the ignition switch is sent to the target engine control unit through the target body controller.

[0040] In an optional implementation, while sending the ignition switch power-off signal to the target engine control unit via the target body controller, the method further includes sending the ignition switch power-off signal to the target vehicle air freshener via the target body controller. Specifically, at the same time as sending the ignition switch power-off signal to the target engine control unit via the target body controller, the ignition switch power-off signal is also sent to the target vehicle air freshener, thereby ensuring the synchronous execution of subsequent operations and providing a basis for subsequent operations.

[0041] In an optional implementation, after sending an ignition switch power-off signal to the target vehicle fragrance through the target vehicle body controller, the method further includes: if the target vehicle fragrance receives the ignition switch power-off signal, controlling the target fragrance motor to perform a shutdown action through the internal controller in the target vehicle fragrance.

[0042] The internal controller can refer to the microcontroller unit (MCU) inside the target car fragrance system. The target fragrance motor can refer to the fragrance motor that matches the target car fragrance system. Typically, a car fragrance system may include an MCU controller, a fragrance motor, and a fragrance cartridge.

[0043] Specifically, after the target vehicle body controller sends an ignition switch power-down signal to the target vehicle fragrance, the target vehicle fragrance receives the ignition switch power-down signal and then controls the target fragrance motor to close the target fragrance box through the internal controller in the target vehicle fragrance, so as to realize the timely closure of the target vehicle fragrance and reduce the use cost of vehicle fragrance.

[0044] S220: Receives the ignition switch down signal through the target engine control unit, controls the target engine to switch from running state to off state, and records the initial switching time of the target engine to off state.

[0045] The initial switching time can refer to the current moment when the target engine switches from the running state to the off state. The running state can refer to the target engine's state signal being "Running". The off state can refer to the target engine's state signal being "Engine off".

[0046] S230: The target engine control unit calculates the duration during which the target engine is in a shut-off state based on the initial switching time to obtain the target duration.

[0047] In one optional implementation, the target engine control unit times the duration of the target engine being in a shut-off state based on the initial switching time to obtain the target duration, including: obtaining the current system time through the target engine control unit, and timing the duration of the target engine being in a shut-off state based on the time difference between the current system time and the initial switching time to obtain the target duration.

[0048] Here, system time can refer to the display time corresponding to the target vehicle. Current system time can refer to the system time corresponding to the current timing moment. Specifically, after the initial switching time of the target engine to the off state is recorded by the target engine control unit, the current system time can be obtained in real time, and the time difference between the current system time and the initial switching time can be calculated as the target duration, providing a valid basis for subsequent operations.

[0049] S240: Match the target duration with the preset delay through the target engine control unit. If the target duration reaches the preset delay, send a disconnect command to the target main relay switch.

[0050] Specifically, the target duration is compared with the preset delay by the target engine control unit. If the target duration is equal to the preset delay, a disconnect command can be sent to the target main relay switch to realize the power supply between the battery and the target vehicle fragrance.

[0051] The technical solution of this invention involves the target vehicle controller sending an ignition switch power-off signal to the target engine control unit when the target vehicle switches from running to off state. The target engine control unit then receives the ignition switch power-off signal, controls the target engine to switch from running to off state, records the initial switching time, and calculates the duration the target engine remains off based on the initial switching time to obtain a target duration. Finally, the target engine control unit matches the target duration with a preset delay. If the target duration reaches the preset delay, a disconnect command is sent to the target main relay switch. This solution addresses the problems of high operating costs and low battery lifespan associated with existing in-vehicle air fresheners, reducing the cost of using in-vehicle air fresheners and extending battery lifespan.

Figure 3 As shown, the system includes: a target body controller 310, a target engine control unit 320, and a target main relay switch 330;

[0054] Among them, the target body controller 310 is used to send an ignition switch power-off signal to the target engine control unit 320 when the target vehicle switches from the running state to the engine off state;

[0055] The target engine control unit 320 is used to receive the ignition switch down signal and control the target engine to enter the shutdown state, and to time the target duration of the target engine in the shutdown state. When the target duration reaches the preset delay, it sends a disconnect command to the target main relay switch 330.

[0056] The target main relay switch 330 is used to receive a disconnect command issued by the target engine control unit 320 to control the target vehicle fragrance to delay power-off.

[0057] The technical solution of this invention involves a target vehicle controller 310 that sends an ignition switch power-off signal to a target engine control unit 320 when the target vehicle switches from a running state to a shut-off state. The target engine control unit 320 receives the ignition switch power-off signal, controls the target engine to enter a shut-off state, and times the target engine's shut-off state for a target duration. When the target duration reaches a preset delay, it sends a disconnect command to a target main relay switch 330. The target main relay switch 330 receives the disconnect command from the target engine control unit 320 to control the delayed power-off of the target vehicle fragrance system. This solves the problems of high operating costs and low battery lifespan of vehicle fragrance systems in the prior art, reducing operating costs and extending battery lifespan.

[0058] Optionally, the control system for delayed power-off of the in-vehicle fragrance may also include: a battery unit for supplying power to the target main relay and the target engine control unit.

[0059] Optionally, the target body controller 310 can also be used to send an ignition switch power-down signal to the target vehicle fragrance system at the same time as sending the ignition switch power-down signal to the target engine control unit 320 through the target body controller 310.

[0062] The target duration is obtained by timing the duration the target engine is in a shut-off state based on the initial switching time.

[0063] Optionally, the target engine control unit 320 can be used for:

[0066] Obtain the current system time, and based on the time difference between the current system time and the initial switching time, time the duration for which the target engine is in the off state is calculated to obtain the target duration.

[0067] Optionally, the control system for delayed power-off of the in-vehicle fragrance may further include: a target in-vehicle fragrance, which, after the ignition switch power-off signal is sent to the target in-vehicle fragrance via the target body controller, controls the target fragrance motor to perform a shutdown action via an internal controller in the target in-vehicle fragrance if the ignition switch power-off signal is received.

[0068] The vehicle fragrance delayed power-off control system provided in this embodiment of the invention can execute the vehicle fragrance delayed power-off control method provided in any embodiment of the invention, and has the corresponding functional modules and beneficial effects of the execution method.

[0069] Figure 4 The diagram illustrates an optional vehicle fragrance delayed power-off control system according to an embodiment of the present invention. Specifically, the battery unit provides power to the target engine control unit and the target vehicle fragrance. A communication connection exists between the target body controller and the target engine control unit, and a target main relay switch is installed between the battery unit and the target vehicle fragrance. When the target vehicle switches from running to off state, the target body controller sends an ignition switch power-off signal to the target engine control unit. Simultaneously, the target body controller sends a shutdown signal to the target vehicle fragrance. The internal controller of the target vehicle fragrance controls the target fragrance motor to perform a shutdown action, thereby turning off the target vehicle fragrance. Then, the target engine control unit receives the ignition switch power-off signal, controls the target engine to enter the off state, and counts the target duration the target engine is in the off state. When the target duration reaches a preset delay, indicating that the target vehicle fragrance has completed the shutdown action, a disconnect command is sent to the target main relay switch to control the target main relay switch to disconnect, thus achieving delayed power-off of the target vehicle fragrance.
