Description

Technical Field

[0001] This invention belongs to the field of vehicle technology, and particularly relates to a vehicle idling speed control method, device, vehicle, and storage medium. Background Technology

[0002] With rising oil prices and consumers becoming increasingly sensitive to vehicle fuel consumption, thermal management and energy efficiency have become areas of growing concern in the design and development process. For gasoline-powered vehicles, it is essential to save fuel as much as possible.

[0003] However, in real life, it often happens that car owners leave their vehicles for a long time without turning off the engine in time, causing the engine to idle for a long time and consume fuel. This not only causes unnecessary fuel waste, but also increases the vehicle's fuel consumption. In severe cases, it may even lead to the exhaustion of fuel, affecting the user's driving experience. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a vehicle idling speed control method, device, vehicle, and storage medium to reduce fuel waste caused by unconventional idling speeds in vehicles.

[0005] A first aspect of the present invention provides a vehicle idling speed control method, comprising:

[0006] Obtain vehicle operating status information;

[0007] Based on the operating status information, determine whether the vehicle is in an abnormal idling state;

[0008] If the vehicle is in an abnormal idling state, the system will detect whether there are any signs of life inside the vehicle and adjust the engine operation status based on the results of the life sign detection and the vehicle's air conditioning status.

[0009] Optionally, the operating status information includes gear position information, door status information, engine operating status information, and driver information;

[0010] Based on the operating status information, determine whether the vehicle is in an abnormal idling state, including:

[0011] If the vehicle's operating status information meets the following conditions simultaneously, the vehicle is determined to be in an abnormal idling state: the gear is in park or neutral, all doors are closed, the engine is on, and there is no one in the driver's seat.

[0012] Optionally, based on the results of vital sign detection and the vehicle's air conditioning status, the vehicle's engine operating status may be adjusted, including:

[0013] If the life detection results indicate the presence of life in the vehicle and the vehicle's air conditioning is on, the engine speed will be adjusted according to the air conditioning's operating power, and the engine will remain on.

[0014] If the life detection results indicate the presence of life in the vehicle and the vehicle's air conditioning is off, the air conditioning will be turned on, and the target temperature of the air conditioning will be set to the preset temperature value. After setting the target temperature, the engine speed will be adjusted according to the operating power of the air conditioning, and the engine will be kept running.

[0015] Optionally, based on the results of vital sign detection and the vehicle's air conditioning status, the vehicle's engine operating status may be adjusted, including:

[0016] If the life detection results show that there are no life signs in the vehicle and the vehicle's air conditioning is on, then the engine speed will be adjusted to the minimum speed at which the air conditioning can be turned on.

[0017] If the vital signs detection results show that there are no vital signs inside the vehicle and the vehicle's air conditioning is off, then the engine speed will be adjusted to the lowest permissible engine speed limit.

[0018] Optionally, after adjusting the vehicle's engine operating status, the following may also be included:

[0019] Detect whether the distance between the vehicle key and the vehicle is greater than a preset distance value;

[0020] If so, monitor the duration of the vehicle's idling in an unconventional idling state;

[0021] When the idling time reaches the first preset time, a prompt message is sent to the user's mobile terminal at a preset frequency. The prompt message is used to remind the user that the vehicle is not turned off.

[0022] When the idling time reaches the second preset time, the engine will be shut off and the vehicle will be locked.

[0023] The second preset duration is longer than the first preset duration.

[0024] Optionally, when the idling time reaches the second preset time, before controlling the engine to shut down and lock the vehicle, the following steps are also included:

[0025] Determine if the vehicle's battery level is greater than a preset first battery level threshold;

[0026] If the vehicle's battery level is not greater than the preset first battery level threshold, the engine will remain running until the vehicle's battery level exceeds the preset first battery level threshold, at which point the engine will be shut off and the vehicle will be locked.

[0027] If the vehicle's battery level exceeds a preset first battery threshold, the engine will be shut off and the vehicle will be locked.

[0028] Optionally, after adjusting the vehicle's engine operating status, the following may also be included:

[0029] Detect whether the distance between the vehicle key and the vehicle is greater than a preset distance value;

[0030] If not, monitor the idling time of the vehicle in an unconventional idling state;

[0031] When the idling time reaches the third preset time, the vehicle's battery level is detected. If the vehicle's battery level is greater than the second preset threshold, the engine is directly shut down.

[0032] And, after the engine is shut down, if the vehicle's battery level is detected to be less than the third preset threshold, the engine is turned on until the vehicle's battery level is greater than the second preset threshold.

[0033] The third preset threshold is less than the second preset threshold.

[0034] A second aspect of the present invention provides a vehicle idle speed control device, comprising:

[0035] The acquisition module is used to acquire vehicle operating status information;

[0036] The adjustment module is used to determine whether the vehicle is in an abnormal idling state based on the operating status information; if the vehicle is in an abnormal idling state, it detects whether there are any signs of life inside the vehicle, and adjusts the engine operating state of the vehicle based on the results of the signs of life detection and the air conditioning status of the vehicle.

[0037] A third aspect of the present invention provides a vehicle including a terminal device. The terminal device includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the steps of the vehicle idling control method of the first aspect described above.

[0038] A fourth aspect of the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the vehicle idling speed control method of the first aspect described above.

[0039] The beneficial effects of the embodiments of the present invention compared with the prior art are as follows:

[0040] This invention detects whether a vehicle is in an unconventional idling state by using its operating status information. When an unconventional idling state is detected, it differentiates between different idling scenarios based on the presence of living beings inside the vehicle and the vehicle's air conditioning status, thereby selecting different engine operating strategies. This reduces fuel waste caused by unconventional idling while still meeting the user's actual needs. This invention effectively saves fuel and improves the user's driving experience.

[0047] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0048] To illustrate the technical solution described in this invention, specific embodiments are described below.

[0049] The vehicle idling speed control method of this invention can be integrated into the vehicle's central control system as an automatic control function. Therefore, the vehicle's central control system can be used to obtain vehicle operating status information, adjust the vehicle's engine operating status, and start / stop the engine, etc.

[0050] See Figure 1 As shown, this embodiment of the invention provides a vehicle idle speed control method, which specifically includes the following steps:

[0051] Step S101: Obtain the vehicle's operating status information.

[0052] In this embodiment of the invention, the central control system of a typical vehicle generally has the function of monitoring the vehicle's operating status information, including gear position information, door status information, engine operating status information, driver information, tire pressure information, headlight status information, fuel level information, and battery level information. Therefore, this embodiment can directly obtain the vehicle's operating status information through the vehicle's central control system.

[0053] Step S102: Based on the operating status information, determine whether the vehicle is in an abnormal idling state.

[0054] In this embodiment, idling is a working condition of a vehicle, referring to the engine running in neutral. The engine speed at idle is called the idle speed. A well-performing engine typically idles at 550-800 rpm. The idle speed can be adjusted by changing the throttle opening and the idle fuel supply. Generally speaking, the optimal idle speed is the lowest speed at which the engine runs smoothly without vibration and with good acceleration within the idle range. The lowest engine speed at which the engine runs stably when the vehicle is parked is called the parking idle speed. When the accelerator pedal is released while the vehicle is moving, maintaining the minimum throttle opening, the engine speed at this point is the same as the parking idle speed; this is called the driving idle speed.

[0055] The unconventional idling state described in this embodiment refers to the condition where a user leaves the vehicle without turning off the engine after parking, which is a type of parking idling. For example, a user may forget to turn off the engine when leaving the vehicle; or they may not turn off the engine and intend to return to the vehicle quickly, but end up not returning for a long time. In such cases, the engine idles for an extended period, consuming fuel and causing unnecessary fuel waste, which may even lead to fuel exhaustion in severe cases.

[0056] Step S103: If the vehicle is in an abnormal idling state, detect whether there are any signs of life inside the vehicle, and adjust the engine operating state of the vehicle according to the results of the life sign detection and the air conditioning status of the vehicle.

[0057] In this embodiment, when a user leaves the vehicle without turning off the engine, various scenarios may arise, making it impossible to simply turn off the engine or reduce its speed. For example, when there are living beings (such as rear passengers or pets) in the vehicle, the user may want the air conditioning to remain running to ensure the comfort of the passengers or pets. Therefore, this embodiment uses the results of the living beings detection and the air conditioning status to differentiate between different scenarios and adjust the vehicle's engine operating status. This effectively saves fuel while meeting the user's actual needs, minimizing any impact on the user's driving experience.

[0058] As can be seen, this invention detects whether a vehicle is in an unconventional idling state by analyzing its operating status information. When an unconventional idling state is detected, it differentiates between different idling scenarios based on the presence of living beings inside the vehicle and the vehicle's air conditioning status, thereby selecting different engine operating strategies. This reduces fuel waste caused by unconventional idling while still meeting the user's actual needs. This invention effectively saves fuel and improves the user's driving experience.

[0059] As one possible implementation method, the operating status information includes gear position information, door status information, engine operating status information, and driver information.

[0060] In step S102, based on the operating status information, it is determined whether the vehicle is in an abnormal idling state, which can be described in detail as follows:

[0061] If the vehicle's operating status information meets the following conditions simultaneously, the vehicle is determined to be in an abnormal idling state: the gear is in park or neutral, all doors are closed, the engine is on, and there is no one in the driver's seat.

[0062] In this embodiment, a more detailed judgment strategy is designed for unconventional idling states. Specifically, the vehicle is judged to be in an unconventional idling state only when the following conditions are met simultaneously: the gear is in Park or Neutral, all doors are closed, the engine is running, and there is no one in the driver's seat. The gear being in Park or Neutral indicates that the vehicle is parked. All doors being closed filters out situations where the owner has exited the vehicle but has not moved far away, such as the owner only briefly stopping to refuel; in such cases, there is no need to implement fuel-saving control strategies. When both of the above conditions are met, and the engine is running and there is no one in the driver's seat, it can be determined that the owner has been away for an extended period without turning off the engine, and the vehicle is in an unconventional idling state, requiring the implementation of fuel-saving control strategies.

[0063] As one possible implementation, step S103, adjusting the vehicle's engine operating state based on the vital sign detection results and the vehicle's air conditioning status, can be detailed as follows:

[0064] If the life detection results indicate the presence of life in the vehicle and the vehicle's air conditioning is on, the engine speed will be adjusted according to the air conditioning's operating power, and the engine will remain on.

[0065] If the life detection results indicate the presence of life in the vehicle and the vehicle's air conditioning is off, the air conditioning will be turned on, and the target temperature of the air conditioning will be set to the preset temperature value. After setting the target temperature, the engine speed will be adjusted according to the operating power of the air conditioning, and the engine will be kept running.

[0066] In this embodiment, the operating power of the air conditioner is determined by the air conditioner's operating mode. Adjusting the engine speed according to the air conditioner's status can reduce the engine's fuel consumption while ensuring user needs are met.

[0067] In the first scenario, if the vital signs detection results show that there are vital signs inside the vehicle and the vehicle's air conditioning is on, it can be determined that the owner needs to turn on the air conditioning to ensure the comfort of other people or pets in the vehicle. Therefore, in this scenario, the engine speed is adjusted according to the operating power of the air conditioning and the engine is kept on to maintain the normal operation of the air conditioning and ensure the comfort of other people or pets in the vehicle.

[0068] In the second scenario, if the life detection results indicate the presence of living beings inside the vehicle and the air conditioning is off, the system can automatically turn on the air conditioning and set the target temperature to a preset value (typically 26°C) to ensure the comfort of other occupants or pets. Simultaneously, the engine speed is adjusted according to the air conditioning's operating power, and the engine remains running. It should be noted that during this process, if human intervention in the air conditioning is detected, the engine speed is adjusted based on the resulting air conditioning status, such as the passenger adjusting the temperature down, up, or turning the air conditioning off, prioritizing human control.

[0069] As one possible implementation, step S103, adjusting the vehicle's engine operating state based on the vital sign detection results and the vehicle's air conditioning status, can be detailed as follows:

[0070] If the life detection results show that there are no life signs in the vehicle and the vehicle's air conditioning is on, then the engine speed will be adjusted to the minimum speed at which the air conditioning can be turned on.

[0071] If the vital signs detection results show that there are no vital signs inside the vehicle and the vehicle's air conditioning is off, then the engine speed will be adjusted to the lowest permissible engine speed limit.

[0072] In the third scenario, when there are no living signs inside the vehicle and the air conditioning is on, it may be because the owner is briefly leaving the vehicle. The engine speed is adjusted to the minimum speed required for the air conditioning to operate, thus keeping only the air conditioning on to save unnecessary fuel consumption and avoid the need for the user to frequently turn on the air conditioning when getting in and out of the vehicle. The engine speed can be automatically restored once the user returns to the vehicle.

[0073] In the fourth scenario, if the life detection results indicate the absence of life signs inside the vehicle and the air conditioning is off, the user may have left for an extended period or forgotten to turn off the engine. In this case, adjusting the engine speed to the minimum permissible speed limit will reduce fuel consumption during idling.

[0074] As one possible implementation, see Figure 2 As shown, after adjusting the vehicle's engine operating state in the third and fourth scenarios, the following is also included:

[0075] Step S1041:

[0076] Detect whether the distance between the vehicle key and the vehicle is greater than a preset distance value;

[0077] If so, monitor the duration of the vehicle's idling in an unconventional idling state;

[0078] When the idling time reaches the first preset time, a prompt message is sent to the user's mobile terminal at a preset frequency. The prompt message is used to remind the user that the vehicle is not turned off.

[0079] When the idling time reaches the second preset time, the engine will be shut off and the vehicle will be locked.

[0080] The second preset duration is longer than the first preset duration.

[0081] In this embodiment, generally, within a certain range, the vehicle can detect the distance between itself and the car key. Therefore, it can be set to determine that the distance between the car key and the vehicle is greater than a preset distance value when the vehicle cannot detect the car key; or, it can be set to determine that the distance between the car key and the vehicle is greater than a preset distance value when the vehicle detects that the car key is not inside the vehicle. In this case, there may be a situation where the owner forgets to turn off the engine. Therefore, it can be set to send a message to the owner's mobile phone every 5 minutes via SMS or APP if the vehicle is idling in an unconventional idling state for 30 minutes, reminding the owner that the engine is not turned off.

[0082] When a vehicle idles at an unconventional speed for 40 minutes, it can automatically shut off the engine to prevent fuel depletion. It can also send a notification message to the owner's mobile phone that "the engine of your car has been automatically shut off," making the owner feel cared for and appreciated.

[0083] In this scenario, after turning off the engine, you should also lock the vehicle to avoid property damage.

[0084] As one possible implementation, in step S1041, before controlling the engine to shut down and lock the vehicle, when the idling time reaches the second preset time, the following steps are also included:

[0085] Determine if the vehicle's battery level is greater than a preset first battery level threshold;

[0086] If the vehicle's battery level is not greater than the preset first battery level threshold, the engine will remain running until the vehicle's battery level exceeds the preset first battery level threshold, at which point the engine will be shut off and the vehicle will be locked.

[0087] If the vehicle's battery level exceeds a preset first battery threshold, the engine will be shut off and the vehicle will be locked.

[0088] In this embodiment, before controlling the engine to shut down and lock the vehicle, it can be determined whether the vehicle's battery level is low. If it is low, the engine can be kept running to charge the vehicle before shutting it down.

[0089] For example, if the vehicle's battery level is no more than 60%, you can charge the vehicle to 60% and then turn off the engine to minimize the risk of the vehicle running out of power due to prolonged parking.

[0090] As one possible implementation, see Figure 2 As shown, after adjusting the vehicle's engine operating state in the third and fourth scenarios, the following is also included:

[0091] Step S1042:

[0092] Detect whether the distance between the vehicle key and the vehicle is greater than a preset distance value;

[0093] If not, monitor the idling time of the vehicle in an unconventional idling state;

[0094] When the idling time reaches the third preset time, the vehicle's battery level is detected. If the vehicle's battery level is greater than the second preset threshold, the engine is directly shut down.

[0095] And, after the engine is shut down, if the vehicle's battery level is detected to be less than the third preset threshold, the engine is turned on until the vehicle's battery level is greater than the second preset threshold.

[0096] The third preset threshold is less than the second preset threshold.

[0097] In this embodiment, generally, within a certain range, the vehicle can detect the distance between itself and the car key. Therefore, it can be set that when the vehicle detects the car key, the distance between the car key and the vehicle is not greater than a preset distance value; or, it can be set that when the vehicle detects the car key is inside the vehicle, the distance between the car key and the vehicle is not greater than a preset distance value. In this case, it might be a scenario where the owner intended to return to the vehicle quickly but didn't return for a long time. Therefore, it can be set that if the vehicle is idling for 50 minutes in an unconventional idling state and the vehicle's battery level is above 80%, the engine will be shut off first to save fuel. Since the vehicle's power is not turned off, it will continue to consume the vehicle's battery power. Therefore, when the vehicle's battery level drops below 30%, the engine can be restarted to charge the vehicle.

[0098] Understandably, in this scenario, the car cannot be locked because the key is inside. Additionally, it could be configured to automatically start the engine when the driver's side door is detected as open, improving convenience.

[0099] In one specific embodiment, the vehicle idle speed control method can be found in [reference needed]. Figure 3 As shown.

[0100] In this embodiment, the detailed steps of the vehicle idle speed control method are as follows:

[0101] (1) When the vehicle is powered on, the controller determines whether the vehicle simultaneously meets the following conditions: the gear is in parking or neutral, all doors are closed, the engine is on, and there are no people in the driver's seat.

[0102] (2) If the condition is not met, the subsequent steps will not be executed; if the condition is met, it will be determined whether the air conditioning cooling is turned on.

[0103] (3) If the air conditioner is not turned on, proceed to step 4; if the air conditioner is turned on, proceed to step 5.

[0104] (4) Determine if there are any signs of life inside the vehicle; if so, automatically turn on the air conditioner and set the temperature to 26°C. Then, the engine speed is determined according to the air conditioner's operating power and the engine is kept running; if there are no signs of life, the engine speed is set to the engine's minimum speed limit.

[0105] (5) Determine if there are signs of life inside the vehicle; if so, determine the engine speed based on the air conditioning operating power and keep the engine running; if not, set the engine speed to the minimum speed at which the air conditioning can be turned on.

[0106] (6) Determine if the car key is inside the car; if it is inside the car, proceed to step 7; otherwise, proceed to step 8.

[0107] (7) The engine running time is timed. When the engine running time is >50 minutes, if the battery charge is >80%, the engine is controlled to shut down. At this time, the controller is always in a non-sleep state. After shutting down, it is determined whether the battery charge is <30%. If it is, the engine is controlled to start and the engine charges the battery. The controller continues to determine whether the battery charge is >80%. If it is not, the engine continues to start. If it is determined, the controller controls the engine to shut down. After the engine is shut down, the engine is automatically started when the driver's side door is detected to be open.

[0108] (8) The engine running time is timed. When the engine running time is >30 minutes, the information that the engine is not turned off is sent to the owner's mobile phone every 5 minutes to remind the owner that the vehicle is not turned off. When the engine running time is >40 minutes, it is determined whether the battery charge is >60%. If not, the engine is kept on to charge the battery. If it is, the controller controls the engine to turn off and then the vehicle is locked.

[0109] This invention, by determining different conditions and different scenarios, selects different engine operating strategies, which can effectively save fuel. At the same time, under certain conditions, when the customer returns to the car, the vehicle recognizes the driver's entry and automatically starts the engine, improving the customer's perception and making the vehicle more intelligent.

[0110] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

After setting the target temperature, the engine speed will be adjusted according to the operating power of the air conditioning, and the engine will be kept running.

[0120] As one possible implementation, adjustment module 42 is specifically used for:

[0121] If the life detection results show that there are no life signs in the vehicle and the vehicle's air conditioning is on, then the engine speed will be adjusted to the minimum speed at which the air conditioning can be turned on.

[0122] If the vital signs detection results show that there are no vital signs inside the vehicle and the vehicle's air conditioning is off, then the engine speed will be adjusted to the lowest permissible engine speed limit.

[0130] Determine if the vehicle's battery level is greater than a preset first battery level threshold;

[0131] If the vehicle's battery level is not greater than the preset first battery level threshold, the engine will remain running until the vehicle's battery level exceeds the preset first battery level threshold, at which point the engine will be shut off and the vehicle will be locked.

[0137] And, after the engine is shut down, if the vehicle's battery level is detected to be less than the third preset threshold, the engine is turned on until the vehicle's battery level is greater than the second preset threshold.

[0138] The third preset threshold is less than the second preset threshold.
