Description

Technical Field

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

[0002] With the continuous improvement of automotive intelligence, the power-off methods for new energy vehicles (EV / PHEV / REEV) have evolved from turning the key or pressing a one-button start switch to automatically powering off when the door is opened or closed, delaying power-off, or automatically powering off when the car is locked, based on certain conditions, bringing a more convenient experience.

[0003] Currently, the coverage of scenarios where vehicles automatically shut down their power is insufficient. In some specific situations, automatic or delayed power-down can negatively impact the user experience. For example, if the driver needs to leave the vehicle for special reasons, but the passengers do not need to leave, the automatic shutdown after the driver's departure will interrupt the air conditioning, affecting cabin comfort. Another example is hybrid vehicles, where the battery's state of charge (SOC) is typically low after long-distance highway driving. If passengers need to rest for an extended period, keeping the air conditioning, audio system, and infotainment system running will gradually deplete the battery. When the battery level drops to a certain threshold, the vehicle will automatically shut down, compromising cabin comfort. Summary of the Invention

[0004] This invention provides a vehicle intelligent power-off control method and device, which can improve the comfort of the in-vehicle environment, ensure the safety of objects left in the vehicle, and broaden the vehicle's usage scenarios.

[0005] To address the aforementioned technical problems, this invention provides a vehicle intelligent power-off control method, comprising:

[0006] When a signal indicating that the driver has left the vehicle is received, liveness detection technology is used to determine whether there are any objects left behind in the vehicle.

[0007] If there are any objects left behind in the current vehicle, check if a vehicle lock signal has been received;

[0008] If a vehicle lock signal is received, check the on / off status of the care mode;

[0009] If the care mode is off, an alarm signal will be issued and the first timer will begin.

[0010] When the first timer reaches the preset first time threshold, the air conditioner is automatically turned on, the harmful gas concentration detection is activated, and the second timer begins.

[0011] When the second timer reaches the preset second time threshold, a reminder message is sent to the driver via the cloud.

[0012] Furthermore, the automatic activation of the air conditioner is specifically achieved as follows:

[0013] Control the air conditioner to turn on automatically, switch the air conditioner to external circulation mode, set the air conditioner temperature to the preset temperature value, and set the air conditioner fan speed to the preset fan speed value.

[0014] Furthermore, when the first timing reaches a preset first time threshold, it also includes:

[0015] Real-time monitoring of power battery charge and fuel level;

[0016] When the power battery charge reaches a preset power threshold and the fuel level does not reach a preset fuel level threshold, a low power warning signal is issued, and the power battery is charged by starting the engine.

[0017] Furthermore, the issuance of the alarm signal includes:

[0018] Control the in-vehicle infotainment system to display a reminder pop-up, control the horn to sound a horn, and control the headlights to flash.

[0019] Furthermore, the step of detecting the on / off state of the care mode upon receiving a vehicle lock signal also includes:

[0020] If the care mode is on, the air conditioner will be turned on automatically, the harmful gas concentration detection will be activated, and the second timer will begin.

[0021] When the second timer reaches the preset second time threshold, a reminder message is sent to the driver via the cloud.

[0022] Furthermore, the step of detecting whether a vehicle lock signal has been received if there is a lingering object on the current vehicle also includes:

[0023] If no lock signal is received, an alarm signal will be issued and the first timer will begin;

[0024] When the first timer reaches the preset first time threshold, the air conditioner is automatically turned on, the harmful gas concentration detection is activated, and the second timer begins.

[0025] When the second timer reaches the preset second time threshold, a reminder message is sent to the driver via the cloud.

[0026] Furthermore, the step of using liveness detection technology to determine whether there is any unattended object in the vehicle when a driver exit signal is received also includes:

[0027] If there are no remaining objects on the current vehicle, apply high-voltage control.

[0028] Furthermore, the high-voltage control includes:

[0029] By starting the engine to charge the power battery, the main positive high voltage relay and the main negative high voltage relay are disconnected, the vehicle's power status is switched to OFF, and the doors are locked.

[0030] Furthermore, the care mode can be activated via the in-vehicle infotainment system or remotely via a connected mobile device.

[0031] Accordingly, the present invention provides a vehicle intelligent power-off control device, including a legacy detection module, a vehicle lock detection module, a mode detection module, a first control module, a second control module, and a third control module;

[0032] The abandoned object detection module is used to determine whether there is an abandoned object in the current vehicle when a driver leaves the vehicle signal is received;

[0033] The vehicle lock detection module is used to detect whether a vehicle lock signal has been received if there is a left-behind object on the current vehicle.

[0034] The mode detection module is used to detect the on / off status of the care mode if a car lock signal is received.

[0035] The first control module is used to issue an alarm signal and start the first timer if the care mode is off.

[0036] The second control module is used to control the air conditioner to turn on automatically, start the detection of harmful gas concentration, and start the second timer when the first timer reaches the preset first time threshold.

[0037] The third control module is used to send a reminder message to the driver via the cloud when the second timer reaches a preset second time threshold.

[0038] This invention provides a vehicle intelligent power-off control method and device. After the driver leaves the vehicle, it utilizes liveness detection technology to determine if any objects are left behind and whether a locking signal has been received. Based on different detection conditions, the vehicle power-off time is dynamically adjusted, expanding the vehicle's usage scenarios. When the driver leaves the vehicle, if any objects are left behind, the safety of the left-behind objects and the comfort of the vehicle's interior environment can be ensured to the greatest extent possible. If the driver forgets to lock the vehicle and there are no living objects inside, rapid power-off can be achieved, saving energy. When a left-behind object needs to rest in the vehicle temporarily or for an extended period, the vehicle's power supply can be ensured through a care mode switch and duration setting on the vehicle's infotainment system. Simultaneously, power supply can be maximized based on fuel and battery levels, thereby ensuring the comfort of the vehicle's interior environment. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0043] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0044] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0045] Example 1

[0046] like Figure 1 The diagram shown is a flowchart of an embodiment of the intelligent vehicle power-off control method provided by the present invention. The method includes steps 101 to 106, and the specific steps are as follows:

[0047] Step 101: When a driver leaves the vehicle signal is received, use liveness detection technology to determine whether there are any objects left behind in the vehicle.

[0048] In the first embodiment of the present invention, when a driver leaves the vehicle signal is received, liveness detection technology can be used to monitor whether there is any living organism (person / pet) left inside the vehicle. If a living organism is found, the vehicle is not locked, and the power is turned off according to the vehicle's current mode.

[0049] Step 102: If there are any objects left in the current vehicle, check if a lock signal has been received.

[0050] In the first embodiment of the present invention, if a left-behind object is detected in the current vehicle, further detection is performed to determine whether a vehicle locking signal triggered by the driver has been received, and corresponding power-down control is performed according to the different vehicle locking signal reception situations.

[0051] Step 103: If a vehicle lock signal is received, check the on / off status of the care mode.

[0052] In the first embodiment of the present invention, if a vehicle lock signal is received from the driver when an object is detected left behind in the current vehicle, it indicates that the driver may have forgotten about the object left in the vehicle. At this time, the on / off state of the care mode in the vehicle is determined. If the care mode is off, the driver is reminded that there is an object left in the vehicle. If the care mode is on, the corresponding mode control is entered.

[0053] Step 104: If the care mode switch is off, an alarm signal is issued and the first timer begins.

[0054] Furthermore, in the first embodiment of the present invention, issuing an alarm signal includes:

[0055] Control the in-vehicle infotainment system to display a reminder pop-up, control the horn to sound a horn, and control the headlights to flash.

[0056] In the first embodiment of the present invention, when a vehicle lock signal is received from the driver when a left-behind object is detected in the current vehicle, and the care mode in the vehicle is turned off, a reminder alarm signal needs to be sent to the driver. This includes controlling the in-vehicle infotainment system to pop up a reminder window, controlling the horn to sound a horn, and controlling the headlights to flash, so as to remind the driver that a left-behind object exists in the vehicle.

[0057] Step 105: When the first timer reaches the preset first time threshold, control the air conditioner to turn on automatically, start the harmful gas concentration detection, and start the second timer.

[0058] In the first embodiment of the present invention, a first timer is started at the same time as the alarm signal is issued. If the driver still does not take further measures when the first timer reaches a preset first time threshold, the air conditioner is automatically turned on to ensure the comfort of the environment inside the vehicle, and the detection of harmful gas concentration is initiated to ensure the health and safety of the object left in the vehicle.

[0059] Furthermore, in the first embodiment of the present invention, controlling the air conditioner to turn on automatically specifically involves:

[0060] Control the air conditioner to turn on automatically, switch the air conditioner to external circulation mode, set the air conditioner temperature to the preset temperature value, and set the air conditioner fan speed to the preset fan speed value.

[0061] In the first embodiment of the present invention, controlling the air conditioner to automatically turn on includes switching the air conditioner to external circulation mode, setting the air conditioner temperature to a preset temperature value, and setting the air conditioner fan speed to a preset fan speed value. As an example, the air conditioner temperature can be set to 24 degrees Celsius, and the air conditioner fan speed can be set to medium speed.

[0062] Furthermore, in the first embodiment of the present invention, when the first timing reaches a preset first time threshold, the method further includes:

[0063] Real-time monitoring of power battery charge and fuel level;

[0064] When the power battery charge reaches a preset power threshold and the fuel level does not reach a preset fuel level threshold, a low power warning signal is issued, and the power battery is charged by starting the engine.

[0065] In the first embodiment of this invention, if a person remains in the vehicle for an extended period, the operation of electrical appliances such as the air conditioner, audio system, and infotainment system will gradually deplete the power battery. When the battery level drops to a certain threshold, the engine will automatically shut off, compromising the comfort of the cabin environment. Therefore, while automatically turning on the air conditioner, the power battery level and fuel level are monitored in real time. When the power battery level reaches a preset threshold and the fuel level does not reach a preset threshold, it is determined that the vehicle's fuel level is sufficient to charge the power battery. Therefore, a low battery warning signal is issued, and the engine is started to charge the power battery.

[0066] Step 106: When the second timer reaches the preset second time threshold, send a reminder message to the driver via the cloud.

[0067] In the first embodiment of the present invention, the care mode is set with a second time threshold. When the timer reaches the second time threshold while in care mode, a reminder signal is sent to the in-vehicle infotainment system, and a pop-up reminder or telephone reminder is sent to the driver's mobile device via the cloud.

[0068] Furthermore, in the first embodiment of the present invention, if a vehicle lock signal is received, detecting the on / off state of the care mode further includes:

[0069] If the care mode is on, the air conditioner will be turned on automatically, the harmful gas concentration detection will be activated, and the second timer will begin.

[0070] When the second timer reaches the preset second time threshold, a reminder message is sent to the driver via the cloud.

[0071] In the first embodiment of the present invention, when a vehicle lock signal is received from the driver when a left-behind object is detected in the current vehicle, and the care mode switch in the vehicle is turned on, the vehicle is controlled to enter care mode, thereby controlling the air conditioner to turn on automatically to ensure the comfort of the in-vehicle environment.

[0072] Furthermore, in the first embodiment of the present invention, if there is a left-behind object on the current vehicle, detecting whether a vehicle lock signal has been received further includes:

[0073] If no lock signal is received, an alarm signal will be issued and the first timer will begin;

[0074] When the first timer reaches the preset first time threshold, the air conditioner is automatically turned on, the harmful gas concentration detection is activated, and the second timer begins.

[0075] When the second timer reaches the preset second time threshold, a reminder message is sent to the driver via the cloud.

[0076] In the first embodiment of the present invention, when an object is detected left behind in the current vehicle and no locking signal is received from the driver, a reminder alarm signal is sent to the driver, and the air conditioner is automatically turned on when the first timer reaches a preset first time threshold to ensure the comfort of the in-vehicle environment.

[0077] Furthermore, in the first embodiment of the present invention, when a driver leaves the vehicle signal is received, determining whether there is any object left behind in the current vehicle using liveness detection technology further includes:

[0078] If there are no remaining objects on the current vehicle, apply high-voltage control.

[0079] In the first embodiment of the present invention, when the driver leaves the vehicle, if the liveness detection technology determines that there is no object left in the vehicle, the high-voltage control is activated to switch the vehicle from a high-voltage state to a low-voltage state.

[0080] Furthermore, in the first embodiment of the present invention, high-voltage control is performed, including:

[0081] By starting the engine to charge the power battery, the main positive high voltage relay and the main negative high voltage relay are disconnected, the vehicle's power status is switched to OFF, and the doors are locked.

[0082] In the first embodiment of the present invention, the vehicle is subjected to high-voltage control, including starting the engine to charge the power battery, controlling the main positive high-voltage relay and the main negative high-voltage relay to disconnect, switching the vehicle power status from ON to OFF, controlling the door to lock, and exiting the care mode.

[0083] Furthermore, in the first embodiment of the present invention, the care mode is activated via the in-vehicle infotainment system or remotely via a connected mobile device.

[0084] In the first embodiment of the present invention, the care mode can be activated by the driver via the in-vehicle infotainment system or remotely via a connected mobile app. The driver can set the duration of the care mode when it is activated. When the in-vehicle care mode is activated and the timeout period has not yet elapsed, if a person or pet is detected inside the vehicle, the vehicle will not be powered down, and the air conditioning will remain at a comfortable temperature, with external air circulation enabled and the vehicle's harmful gas concentration detection function activated. When the in-vehicle care mode is activated and the timeout period has elapsed, if a person or pet is detected inside the vehicle, the vehicle will not be powered down, the air conditioning will remain at a comfortable temperature, with external air circulation enabled and the vehicle's harmful gas concentration detection function activated, and a call will be made to the driver's mobile phone or a pop-up message will be sent to the app to remind the driver that a person or pet has been left inside the vehicle. The driver can remotely control the in-vehicle care mode to continue using the mobile app and set the duration of the mode again. The driver will then be reminded again via phone or app pop-up when the timeout period expires again or when the vehicle's energy is about to run out.

[0085] Example 2

[0086] See Figure 2 This is a flowchart illustrating another embodiment of the intelligent vehicle power-off control method provided by the present invention. The control method is implemented through an intelligent vehicle power-off control system and is applicable to pure electric and hybrid vehicles. The control system includes a body control system (BCM), a vehicle infotainment system (TICE), a vehicle battery box (TBOX), a mobile app, an air conditioning system, an onboard occupant detection system (OMS), a vehicle control unit (PCU / VCU), and a battery management system (BMS).

[0087] In the second embodiment of the present invention, when the BCM detects that the driver has left the vehicle and triggers an active locking action (pressing the remote lock button or the door handle lock button), it checks the care mode switch status of the TICE. If the care mode switch status is off, and the Occupant Monitoring System (OMS) detects a living organism left in the vehicle, the BMS controls the vehicle alarm (honking + flashing lights) to remind the driver, does not perform the locking action, and displays a pop-up window on the vehicle's infotainment system reminding the driver that a person / pet has been left in the vehicle, and starts a first timer. If the first time threshold T1 is reached and the driver still has not taken further action, the BCM controls the air conditioning to automatically turn on, set the comfort temperature, switch to external circulation, and start the timer. When the timer reaches the second time threshold T2, a phone call is made to the mobile phone via the TBOX or an app pop-up window is sent to remind the customer that a person / pet has been left in the vehicle. If the care mode switch status is on, the BCM controls the air conditioning to automatically turn on, set the comfort temperature, switch to external circulation, and start the timer. When the timer reaches the second time threshold T2, a phone call is made to the mobile phone via the TBOX or an app pop-up window is sent to remind the customer that a person / pet has been left in the vehicle.

[0088] In the second embodiment of the present invention, when the BCM detects that the driver has left the vehicle and has not triggered an active locking action, if the OMS monitors that a living organism has been left inside the vehicle, the BMS controls the vehicle alarm (honking horn + flashing lights) to remind the driver, does not perform the locking action, and the vehicle infotainment system displays a pop-up reminder that a person / pet has been left inside the vehicle, and begins a first timer. If the first time threshold T1 is reached and the driver still has not taken further action, the BCM controls the air conditioning to automatically turn on, set the comfort temperature, switch to external circulation, and start the timer. When the timer reaches the second time threshold T2, a phone call is made to the mobile phone via the TBOX or an app pop-up is sent to remind the customer that a person / pet has been left inside the vehicle. If the care mode switch is in the "on" state, the BCM controls the air conditioning to automatically turn on, set the comfort temperature, switch to external circulation, and start the timer. When the timer reaches the second time threshold T2, a phone call is made to the mobile phone via the TBOX or an app pop-up is sent to remind the customer that a person / pet has been left inside the vehicle.

[0089] In the second embodiment of the present invention, when the BCM detects that the driver has left the vehicle and has not triggered an active vehicle locking action, the OMS monitors whether any living organisms (people / pets) are left inside the vehicle. If the OMS detects that no living organisms are left inside the vehicle, the OMS sends a signal to the BCM, the BCM controls the entire vehicle to lock and power down, and the PCU / VCU controls the high voltage to power down.

[0090] In the second embodiment of the present invention, when the BCM detects that the driver has left the vehicle and triggers an active locking action (by pressing the remote locking button or the door handle locking button), the Occupant Monitoring System (OMS) monitors whether any living organisms (people / pets) are left inside the vehicle. If no living organisms are left inside the vehicle, the OMS sends a signal to the BCM, which then controls the entire vehicle to lock and power down, and the PCU / VCU controls the high voltage to power down.

[0091] In the second embodiment of the present invention, when the PCU / VCU sends a high-voltage reduction command, the PCU controls the engine to start and charge the power battery. When the BMS receives the high-voltage reduction command from the PCU / VCU, it controls the main positive high-voltage relay and the main negative high-voltage relay to disconnect.

[0092] In the second embodiment of the present invention, the driver can remotely activate the in-vehicle care mode via the in-vehicle infotainment system or a mobile app, and set the duration of the mode (i.e., the second time threshold). When the in-vehicle care mode is activated but the second time threshold T2 has not been reached, if the OMS detects a person or pet in the vehicle, the BCM does not power down the entire vehicle, but keeps the air conditioning set to a comfortable temperature, the external air circulation activated, and the vehicle's harmful gas concentration detection function active. If the in-vehicle care mode is activated and the second time threshold T2 has been reached, and the OMS detects a person or pet in the vehicle, the BCM does not power down the entire vehicle, but keeps the air conditioning set to a comfortable temperature, the external air circulation activated, and the vehicle's harmful gas concentration detection function active. The infotainment system calls the driver's mobile phone via the TBOX or sends an app pop-up notification to remind the customer that a person or pet has been left in the vehicle. The driver can remotely control the in-vehicle care mode to continue using the mobile app, setting the mode and maintaining the second time threshold T2. When the second time threshold T2 is reached again or the vehicle's energy is about to run out, the driver will be reminded again via phone or app pop-up.
