Description

Technical Field

[0001] This application relates to vehicle technology, and in particular to a method, device, system, and vehicle for reminding users to forget their vehicle keys. Background Technology

[0002] In recent years, with the rapid development of China's economy and the significant improvement of people's living standards, vehicles have gradually become a common means of transportation. Regarding vehicle convenience design, especially in terms of ignition and starting, there has been a gradual transition from traditional mechanical key start to keyless and contactless start, greatly simplifying the steps for users and making vehicle use more convenient. Vehicles equipped with keyless and contactless start functions can automatically unlock / lock when the owner approaches or leaves the vehicle with the key, and the vehicle will start automatically when the door is opened. This has gradually fostered the habit of not needing to take out the key to use the car. Therefore, it is common for keys to be left inside the vehicle when leaving, posing a potential threat to the owner's property security.

[0003] Existing vehicle key reminder systems can display a reminder and emit a prompt sound on the vehicle's large screen when the car door is opened.

[0004] However, current key forgetting reminders cannot truly identify the owner's intention to leave the vehicle, lack accurate identification of operating conditions and intelligent reminders, resulting in frequent reminders and seriously affecting the owner's user experience.

[0045] Figure 4 This is a schematic diagram of a vehicle key forgetting reminder system provided in an embodiment of this application. Detailed Implementation

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] With the continuous development of vehicle technology, vehicles have gradually been equipped with functions such as keyless start and contactless start. Users can control the vehicle using a single remote key and / or a mobile phone Bluetooth key. When the owner approaches or leaves the vehicle with the key, the vehicle can automatically unlock or lock. Users have gradually developed the habit of not needing to take out their keys to use the car, which often leads to situations where the keys are left inside the car. In related technologies, when the car door is opened, a reminder is issued through the vehicle's large infotainment screen. However, this system cannot recognize the owner's intention to leave the vehicle, resulting in frequent reminders and a degraded user experience.

[0048] In response, this application provides a vehicle key forgetting reminder method, which can accurately identify the vehicle owner's opening of the car door, leaving the car, closing the car door, and moving away from the vehicle. It can also provide timely and effective reminders when the vehicle owner leaves the car and when the owner forgets the single remote key and mobile phone Bluetooth key inside the car. At the same time, it reduces the probability of false alarms and missed alarms, effectively improving the vehicle owner's car use experience and protecting the vehicle owner's property safety.

[0049] like Figure 1 As shown, this application provides a vehicle key forgetting reminder method. The executing entity of this method can be an in-vehicle controller, which can be a dedicated controller, a general-purpose controller, or a controller with other uses, such as an in-vehicle infotainment system controller, also known as an IHU (Infotainment Head Unit) controller. The method includes:

[0050] Step S101: In response to a vehicle door opening event, obtain the vehicle status information;

[0051] Step S102: In response to the vehicle status information meeting the preset forgetting condition, detect the location of the wireless key;

[0052] Step S103: In response to detecting that the wireless key is inside the vehicle, issue a forgotten reminder alarm.

[0053] The vehicle key forgetting reminder method provided in this application collects vehicle status information after the car door is opened to comprehensively determine the owner's intention to leave the vehicle and determines the location of the wireless key. It accurately identifies situations where keys may be forgotten. If the owner leaves the vehicle and the key is left inside, a forgetting alarm is issued to remind the owner, reducing false alarms and missed alarms for key forgetting reminders and improving the user experience.

[0054] like Figure 2 As shown in the embodiment of this application, another method for reminding users to forget their vehicle keys is provided. The executing entity of this method can be an in-vehicle controller, which can be a dedicated controller, a general-purpose controller, or a controller with other uses, such as a vehicle infotainment screen controller. The method includes:

[0055] Step S201: Detect the vehicle door opening event.

[0056] In some optional embodiments, before detecting a vehicle door opening event, the vehicle key forgetting reminder method further includes: the vehicle key forgetting reminder system performing a self-check to determine if the opening requirements are met. After the vehicle ignition switch is switched from the OFF position to the ON position, the vehicle key forgetting reminder system completes a self-check within a certain period of time. If the system meets the opening requirements, it remains active and the vehicle's infotainment screen (or central control screen) does not display any related information, preparing for the next step of testing; if the system does not meet the opening requirements, it indicates a system malfunction or functional failure, the system shuts down, and the infotainment screen displays a fault exit message.

[0057] Understandably, this step includes detecting the controllers and other devices involved in the vehicle key forgetting reminder method, and the activation requirement may be detecting that the vehicle key forgetting reminder system can normally collect and transmit information.

[0058] In some optional embodiments, the vehicle key forgetting reminder method further includes detecting whether the power supply is in the ON position before responding to a vehicle door opening event. If the power supply is detected to be in the ON position, i.e., the vehicle is not powered off, the detection of a door opening event begins; if the power supply is detected to be in the non-ON position, the forgetting reminder system is turned off.

[0059] In some optional embodiments, the door opening event includes the recognition of one or more door opening information, which may be provided by the body control module (BCM). If the vehicle does not recognize any door opening information, step S201 is periodically continued; if the vehicle recognizes one or more door opening information, the process proceeds to step S202.

[0060] Step S202: Obtain vehicle status information.

[0061] In some optional embodiments, the vehicle information status includes automatic parking status information and information on the presence or absence of occupants in all seats. The automatic parking status information can be provided by the Advanced Driving Assistance System (ADAS), and the information on the presence or absence of occupants in all seats can include information on whether the driver's seat, front passenger seat, and rear seats are occupied. This information is provided by the Driver Monitoring System (DMS), Air Bag Module (ABM), and Occupant Monitoring System (OMS), respectively. In other optional embodiments, the presence or absence of occupants in all seats can be identified using seat gravity sensors combined with in-vehicle cameras. If both the seat gravity sensors and the in-vehicle camera detect that the vehicle is unoccupied, then the vehicle is determined to be unoccupied.

[0062] Step S203: Determine whether the vehicle status information meets the preset forgetting conditions.

[0063] In some optional embodiments, the preset forgetting condition includes: the automatic parking status information is that the vehicle is in a non-automatic parking state, and the information on whether there are people in the vehicle seats changes from "there are people in the vehicle seats" to "there are no people in the vehicle seats". If it is determined that the vehicle status information does not meet the preset forgetting condition, step S201 is executed again; if it is determined that the vehicle status information meets the preset forgetting condition, step S204 is executed.

[0064] In some optional embodiments, after obtaining the vehicle status information, if the automatic parking information in the vehicle status information indicates that the vehicle is in an automatic parking state, the automatic parking status information is continuously detected until the automatic parking state changes to the vehicle being in a non-automatic parking state. After that, it is determined whether the vehicle status information meets the preset forgetting conditions.

[0065] It's understandable that when a vehicle is in automatic parking mode, the owner may temporarily leave the vehicle, making a forgotten key reminder issued by the vehicle in this state potentially unnecessary. However, if the system detects that the vehicle is in non-automatic parking mode after a door is opened, and recognizes that all seats have changed from occupied to unoccupied, it can be determined that the owner has finished driving and left the vehicle, which is a situation where a forgotten key might occur.

[0066] Step S204: Detect the location of the wireless key.

[0067] In some optional embodiments, the wireless key includes a single remote control key and / or a mobile phone Bluetooth key. If the wireless key is detected not in the vehicle, step S201 is executed again; if the wireless key is detected in the vehicle, step S205 is executed.

[0068] Understandably, a standalone remote key allows for remote unlocking and locking without inserting a key into the lock. The vehicle's control system typically receives signals from the standalone key, authenticates them, and then executes the action. A mobile Bluetooth key, on the other hand, uses a mobile app to provide functions such as keyless start and keyless locking. The Bluetooth keys for both the mobile key and the vehicle are managed and distributed through the OEM's backend system. For example, when allocating Bluetooth key keys, the OEM sends information to both the mobile key and the vehicle; the vehicle only responds to the authorized mobile key. The mobile Bluetooth key is a virtual key, and multiple keys can be assigned, managed centrally by a server. The remote key, however, is a physical key and cannot be freely created. Only one type of key can be used, or both can be used simultaneously.

[0069] In some optional embodiments, the wireless signal of the individual remote key is detected by an onboard antenna. When the wireless signal of the individual remote key is detected, it is determined whether the individual remote key is located inside the vehicle. For example, the body controller may have multiple onboard antennas installed inside the vehicle. When the multiple onboard antennas detect the radio wave signal emitted by the individual remote key, the individual remote key is authenticated. After authentication, the signal strength of the radio wave signal received by the multiple onboard antennas is determined, and the distance between the multiple onboard antennas and the individual remote key is determined based on the signal strength. Optionally, the body controller may install at least three onboard antennas at different locations inside the vehicle. Based on the determined distances between the multiple onboard antennas and the individual remote key, multiple circles are determined, each centered on one of the onboard antennas and with a radius equal to the distance between the multiple onboard antennas and the individual remote key. The intersection of the multiple circles is used as the location information of the individual remote key to determine whether the individual remote key is located inside the vehicle.

[0070] In some optional embodiments, the Bluetooth signal of the mobile phone Bluetooth key is detected by an in-vehicle Bluetooth module. When the Bluetooth signal of the mobile phone Bluetooth key is detected, it is determined whether the mobile phone Bluetooth key is located inside the vehicle. This in-vehicle Bluetooth module can be integrated into an electronic control unit such as a Telematics Box (T-BOX) or a vehicle body controller. For example, the in-vehicle Bluetooth module can periodically send Bluetooth signals carrying a request to obtain the key of the mobile phone Bluetooth key. After receiving the request from the mobile phone Bluetooth key, the mobile phone Bluetooth key sends a Bluetooth signal to the in-vehicle Bluetooth key, carrying the key of the mobile phone Bluetooth key and the transmission strength of the Bluetooth signal. At least one in-vehicle Bluetooth module located in different positions on the vehicle receives the Bluetooth signal sent by the in-vehicle Bluetooth module, records the reception strength of the Bluetooth signal, and obtains the key of the mobile phone Bluetooth key. Each vehicle Bluetooth module matches the key of the mobile phone Bluetooth key with a pre-stored key. When the mobile phone Bluetooth key matches the pre-stored key, it obtains the transmission strength and reception strength of the mobile phone Bluetooth key. Based on the transmission and reception strengths of the Bluetooth signal, and the pre-stored relationship between the strength changes and distance of the Bluetooth signal, it determines the distance between the vehicle Bluetooth module and the mobile phone Bluetooth key, thus determining the distance between each vehicle Bluetooth module and the mobile phone Bluetooth key. Based on the determined distances between multiple vehicle Bluetooth modules and the mobile phone Bluetooth key, the location information of the mobile phone Bluetooth key is determined. This method is similar to determining the location information of a single remote control key based on the distances between multiple vehicle antennas and a single remote control key, and will not be elaborated further here.

[0071] Optionally, after receiving the Bluetooth signal sent by the mobile phone Bluetooth key, the vehicle's Bluetooth module can determine the distance between itself and the mobile phone Bluetooth key based on the time difference between sending and receiving the Bluetooth signal, as well as the Bluetooth signal propagation speed. Furthermore, after receiving the Bluetooth signal from the mobile phone Bluetooth key, the vehicle's Bluetooth module can determine the angle at which the Bluetooth signal was received and define this angle as the relative angle between itself and the mobile phone Bluetooth key. Therefore, based on the communication distance and relative angle between the vehicle's Bluetooth module and the mobile phone Bluetooth key, the location information of the mobile phone Bluetooth key can be determined.

[0072] Step S205: Detect whether the vehicle status information meets the preset forgetting conditions and whether the wireless key remains in the vehicle for a duration greater than the first threshold.

[0073] If the duration exceeds the first threshold, it indicates that the automatic parking status information is that the vehicle is in a non-automatic parking state. Regarding the presence or absence of passengers, if the vehicle status information remains unchanged after all seats change from occupied to unoccupied, and the wireless key has been detected in the vehicle for more than the first threshold, the system enters a Level 1 forgotten reminder state and proceeds to step S206. If the above conditions change, it is considered that the owner did not intend to leave the vehicle, and the process proceeds to step S201.

[0074] Step S206: Issue a Level 1 Forgot Reminder Alert.

[0075] In some alternative embodiments, visual alerts are provided via an in-vehicle screen and audio alerts are provided via an in-vehicle audio system, both of which are controlled by the in-vehicle infotainment screen controller.

[0076] Step S207: Detect whether the duration of the state continuation condition is greater than the second threshold.

[0077] In some optional embodiments, the conditions for this state to continue include: the vehicle is unoccupied, the vehicle power status is not ON, and the wireless key is located inside the vehicle.

[0078] If the duration of the status condition exceeds the second threshold, it is considered that the vehicle owner has moved away from the vehicle, and the system needs to enter the second-level forgotten reminder state, i.e., proceed to step S208. If the above conditions change, it is considered that the vehicle owner did not intend to move away from the vehicle, and the system will proceed to continue executing step S201.

[0079] Step S208: Issue a Level 2 Forgot Reminder Alert.

[0080] In some optional embodiments, when the wireless key is a standalone remote key, a mobile application notification message is sent, and an SMS message is sent to the vehicle owner's mobile phone and / or a phone call is made; when the wireless key is a mobile phone Bluetooth key, a mobile application notification message is sent, and an SMS message is sent to the emergency contact's mobile phone and / or a phone call is made.

[0081] Understandably, the in-vehicle T-BOX can respond to the vehicle entering a Level 2 forgotten reminder state and send text messages and / or make phone calls to specific mobile phones through the Telematics Service Provider (TSP) platform.

[0082] The vehicle key forgetting reminder method provided in this application collects vehicle status information after the car door is opened to comprehensively determine the owner's intention to leave the vehicle and determines the location of the wireless key. It accurately identifies situations where the key may be forgotten. If the owner leaves the vehicle and the key is left inside, a forgetting alarm is issued to remind the owner, reducing false alarms and missed alarms for key forgetting reminders and improving the user experience.

[0083] Figure 3 This is a schematic diagram illustrating the structure of a vehicle key forgetting reminder device 300 according to an exemplary embodiment. The vehicle key forgetting reminder device 300 may include:

[0084] The acquisition module 301 is used to acquire vehicle status information in response to a vehicle door opening event. The vehicle status information includes automatic parking status information and whether there are any occupants in the vehicle seats.

[0085] The detection module 302 is used to detect the location of the wireless key in response to the vehicle status information reaching a preset forgetting condition. The preset forgetting condition includes: the automatic parking status information indicating the vehicle is in a non-automatic parking state, and the vehicle occupancy information indicating the vehicle is no longer occupied. The wireless key includes a single remote key and / or a mobile phone Bluetooth key. Detecting the location of the wireless key includes: detecting the wireless signal of the single remote key via the vehicle's antenna; when the wireless signal of the single remote key is detected, identifying whether the single remote key is located inside the vehicle; and detecting the Bluetooth signal of the mobile phone Bluetooth key via the vehicle's Bluetooth module; when the Bluetooth signal of the mobile phone Bluetooth key is detected, identifying whether the mobile phone Bluetooth key is located inside the vehicle.

[0086] Alarm module 303 is used to issue a forgotten reminder alarm in response to detecting that the wireless key is inside the vehicle. Issuing the forgotten reminder alarm in response to detecting that the wireless key is inside the vehicle includes: entering a first-level forgotten reminder state if the vehicle status information meets preset forgotten conditions and the duration of the wireless key being detected inside the vehicle exceeds a first threshold; in response to entering the first-level forgotten reminder state, detecting the duration of the state's conditions, which include: all seats in the vehicle are empty, the vehicle power status is in the off-ON position, and the wireless key is inside the vehicle; and entering a second-level forgotten reminder state if the duration of the state's conditions exceeds a second threshold. Issuing the forgotten reminder alarm also includes: issuing a first-level forgotten alarm in response to entering the first-level forgotten reminder state; and issuing a second-level forgotten alarm in response to entering the second-level forgotten reminder state. Issuing the first-level forgotten alarm includes: providing a visual reminder via the in-vehicle screen and an audio reminder via the in-vehicle audio system. Issue a Level 2 Forgot Alert, including: when the wireless key is a standalone remote key, sending a mobile application notification message and sending an SMS to the owner's mobile phone and / or making a phone call; when the wireless key is a mobile phone Bluetooth key, sending a mobile application notification message and sending an SMS to the emergency contact's mobile phone and / or making a phone call.

[0087] It should be noted that the vehicle key forgetting reminder device provided in the above embodiments is only an example of the division of the above functional modules. In actual applications, the above functions can be assigned to other functional modules as needed to complete all or part of the functions described above. In addition, the user identification device and user identification method embodiments provided in the above embodiments belong to the same concept, and their specific implementation process can be found in the method embodiments, which will not be repeated here.

[0088] The vehicle key forgetting reminder device provided in this application collects vehicle status information after the car door is opened to comprehensively determine the owner's intention to leave the vehicle and determines the location of the wireless key. If the owner leaves the vehicle and the key is forgotten inside, a forgetting alarm is issued to remind the owner. Compared to existing technologies that issue an alarm whenever the car door is opened, the vehicle key forgetting reminder device provided in this application accurately identifies situations where keys may be forgotten, reducing false alarms and missed alarms, and improving the user experience.

[0089] Figure 4 This is a schematic diagram illustrating the structure of a vehicle key forgetting reminder system 400 according to an exemplary embodiment. The vehicle key forgetting reminder system includes:

[0090] The body controller 401 is used to respond to door opening events, detect the wireless signal of the individual remote key, and provide vehicle power status information. The body controller 401 collects various signals, including door opening information and door lock status information, and processes these signals according to the needs of body control. Finally, it controls the body's electrical system based on the processing results. Common controlled objects include door locks, lights, air conditioning, and horn.

[0091] The vehicle-mounted Bluetooth module 402 is used to detect the Bluetooth signal of the mobile phone Bluetooth key. The vehicle-mounted Bluetooth (BLE, Bluetooth Low Energy) module 402 uses short-range wireless communication technology. When communication is needed, the vehicle-mounted Bluetooth module 402 continuously broadcasts signals at regular intervals. After receiving the signal, the mobile phone Bluetooth key sends a connection request to the vehicle-mounted Bluetooth module 402. After successful authentication, a connection is established between the vehicle-mounted Bluetooth module 402 and the mobile phone Bluetooth key for communication.

[0092] The intelligent driving controller 403 provides automatic parking status information. It assists in driving by collecting data from the vehicle's internal and external environment and using algorithms to identify moving and static objects. Typically, the intelligent driving controller 403 comprises multiple subsystems; the automatic parking status information can be provided by the automatic parking system within the ADAS (Advanced Driver Assistance Systems).

[0093] The driver monitoring system 404 is used to provide information on whether the driver's seat is occupied. The driver monitoring system 404 uses sensors, optical cameras, and infrared cameras installed in the vehicle to perform functions such as driver identification, driver fatigue monitoring, driver attention monitoring, and monitoring of dangerous driving behaviors.

[0094] The airbag controller 405 is used to provide information about whether there is someone in the front passenger seat. The airbag controller 405 is typically installed in front of the front passenger seat and uses the front passenger seat gravity sensor signal to determine whether someone is in the front passenger seat.

[0095] The occupant monitoring system 406 provides information on whether there are occupants in the rear seats. The occupant monitoring system 406 monitors occupant behavior using devices such as seat sensors, cameras, and millimeter-wave radar, and identifies occupant behavior through behavioral analysis algorithms. It then alerts the occupants to safety issues, effectively ensuring driving safety and occupant safety.

[0096] The vehicle infotainment screen controller 407 receives signals from the body control controller, in-vehicle Bluetooth module, intelligent driving controller, driver monitoring system, and occupant monitoring system. When a single remote key and / or a mobile phone Bluetooth key is detected inside the vehicle, it issues a Level 1 forgotten alarm, including providing visual reminders via the in-vehicle screen and audible reminders via the in-vehicle audio system. It also requests the vehicle networking system to issue a Level 2 forgotten alarm, including sending mobile application notification messages and sending SMS messages and / or making phone calls to the owner's mobile phone. The vehicle infotainment screen controller 407 is equipped with a central control screen and communicates via a CAN bus. It can display the acquired signals on the central control screen and issue audible reminders, and also requests the vehicle networking system to issue a Level 2 forgotten alarm.

[0097] The vehicle key forgetting reminder system provided in this application embodiment can comprehensively determine the owner's intention to leave the vehicle by collecting vehicle status information after the car door is opened, and determine the location of the wireless key.
