Description

Technical Field

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

[0002] The current level of automobile intelligence is constantly improving. The power-off method of new energy vehicles (EV / PHEV / REEV) has evolved from turning the key or pressing a one-button start switch to automatic power-off when opening / closing the door after certain conditions are met, delayed power-off or automatic power-off when locking the car, bringing a convenient experience.

[0003] At present, the coverage of car power-off scenarios is insufficient. In some special scenarios, automatic power-off or delayed power-off will affect 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 vehicle, the vehicle will automatically shut down and power off after the driver leaves, which will cause the vehicle's air conditioning to be interrupted and affect the comfort in the cabin. For another example, the SOC of the power battery of a hybrid vehicle is usually not high after long-distance high-speed driving. At this time, if the passengers need to rest for a long time in the car, keeping the air conditioning, audio, infotainment system and other electrical appliances running normally will gradually consume the power of the power battery. When the power is low to a certain threshold, it will automatically shut down and power off, resulting in the inability to maintain a comfortable environment in the cabin. Summary of the invention

[0004] The present invention provides a vehicle intelligent power-off control method and device, which can improve the comfort of the vehicle interior environment, ensure the safety of objects left in the vehicle, and expand the vehicle usage scenarios.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0044] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0045] Example 1

[0046] like Figure 1 FIG. 1 is a flow chart of an embodiment of a vehicle intelligent power-off control method provided by the present invention. The method includes steps 101 to 106, and each step is specifically as follows:

[0047] Step 101: When a driver leaves the vehicle, a liveness detection technology is used to determine whether there is an object left behind in the current vehicle.

[0048] In the first embodiment of the present invention, when a driver leaving vehicle signal is received, the liveness detection technology can be used to monitor whether there is a living organism (person / pet) left in the current vehicle. If there is a living organism left, the vehicle is not locked, and the corresponding power-off control is performed according to the mode of the vehicle.

[0049] Step 102: If there is an object left behind in the current vehicle, detect whether a vehicle lock signal is received.

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

[0051] Step 103: If a vehicle locking signal is received, the switch status of the care mode is detected.

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

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

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

[0055] Control the car's computer to pop up reminder pop-ups, control the horn to honk, and control the lights to flash.

[0056] In the first embodiment of the present invention, when a vehicle lock signal is received from the driver when it is detected that there is an object left behind in the current vehicle, and the switch state of the care mode in the vehicle is off, a reminder alarm signal needs to be sent to the driver, including controlling the vehicle computer to pop up a reminder pop-up window, controlling the horn to sound a whistle, and controlling the lights to flash, so as to remind the driver that there is an object left behind in the car.

[0057] Step 105: When the first timing reaches the preset first time threshold, the air conditioner is controlled to automatically turn on, the harmful gas concentration detection is started, and the second timing begins.

[0058] In the first embodiment of the present invention, a first timing starts when an alarm signal is issued. If the driver still does not take further measures when the first timing reaches a preset first time threshold, the air conditioner is automatically turned on to ensure the environmental comfort in the car, and harmful gas concentration detection is started to ensure the health and safety of objects left in the car.

[0059] Further, in the first embodiment of the present invention, the air conditioner is controlled to be automatically turned on, specifically:

[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 air volume to the preset air volume value.

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

[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 and fuel levels;

[0064] When the power battery power reaches a preset power threshold and the oil level does not reach the preset oil level threshold, a low power reminder signal is sent, and the power battery is charged by starting the engine.

[0065] In the first embodiment of the present invention, if the left-behind object rests in the car for a long time, the air conditioner, audio system, infotainment system and other electrical appliances are kept running normally, which will gradually consume the power of the power battery, and when the power is low to a certain threshold, the engine will automatically shut down and the power will be turned off, resulting in the inability to maintain a comfortable environment in the cabin. Therefore, while controlling the air conditioner to turn on automatically, the power battery and oil level in the car are monitored in real time. When the power battery reaches the preset power threshold and the oil level does not reach the preset oil level threshold, it is determined that the oil level of the vehicle can charge the power battery, so a low power reminder signal is issued, and the power battery is charged by starting the engine.

[0066] Step 106: When the second timing reaches the preset second time threshold, a legacy reminder message is sent to the driver via the cloud.

[0067] In the first embodiment of the present invention, the care mode is provided with a second time threshold. When the timing time reaches the second time threshold in the care mode, a reminder signal is sent to the vehicle computer in the vehicle, and a pop-up reminder or a telephone reminder is sent to the driver's mobile terminal through the cloud.

[0068] Furthermore, in the first embodiment of the present invention, if a vehicle locking signal is received, the switch state of the care mode is detected, and the method further includes:

[0069] If the switch state of the care mode is on, the air conditioner is automatically turned on, the harmful gas concentration detection is started, and the second timing begins;

[0070] When the second timing reaches a preset second time threshold, a legacy 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 it is detected that there is an object left behind in the current vehicle, and the switch state of the care mode in the vehicle is on, the vehicle is controlled to enter the care mode, thereby controlling the air conditioner to turn on automatically to ensure the comfort of the vehicle interior environment.

[0072] Further, in the first embodiment of the present invention, if there is an object left behind in the current vehicle, detecting whether a vehicle locking signal is received also includes:

[0073] If the vehicle locking signal is not received, an alarm signal is issued and the first timer starts;

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

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

[0076] In the first embodiment of the present invention, when it is detected that there is an object left behind in the current vehicle and no vehicle lock signal is received from the driver, a reminder alarm signal is sent to the driver, and the air conditioner is controlled to turn on automatically when the first timing reaches a preset first time threshold to ensure the comfort of the vehicle interior environment.

[0077] Furthermore, in the first embodiment of the present invention, when a driver leaving vehicle signal is received, a liveness detection technology is used to determine whether there is an object left behind in the current vehicle, and the method further includes:

[0078] If there is no remaining object in the current vehicle, perform high-voltage control.

[0079] In the first embodiment of the present invention, when the driver leaves the vehicle, if it is determined by liveness detection technology that there is no object left behind in the current vehicle, the high-pressure control is controlled to switch the vehicle from a high-pressure state to a low-pressure state.

[0080] Further, in the first embodiment of the present invention, the lower high pressure 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 controlled to be disconnected, the power state of the entire vehicle is switched to OFF, and the vehicle doors are controlled to be locked.

[0082] In the first embodiment of the present invention, the vehicle is controlled to be under high voltage, including starting the engine to charge the power battery, controlling the main positive high voltage relay and the main negative high voltage relay to be disconnected, and switching the power state of the whole vehicle from ON to OFF, controlling the door to be locked, and exiting the care mode.

[0083] Furthermore, in the first embodiment of the present invention, the care mode is activated via the in-vehicle computer or remotely activated via an associated mobile terminal.

[0084] In the first embodiment of the present invention, the care mode can be turned on by the driver in the car computer or remotely turned on by the associated mobile phone APP. The driver can set the duration of the mode when turning on the care mode. When the in-car care mode is turned on and the timing time has not been reached, if it is detected that there are people or pets in the car, the whole vehicle will not be controlled to be powered off, and the air conditioner will be set at a comfortable temperature, the external circulation will be turned on, and the concentration of harmful gases in the car will be detected. When the in-car care mode is turned on and the timing time has been reached, if it is detected that there are people or pets in the car, the whole vehicle will not be controlled to be powered off, and the air conditioner will be set at a comfortable temperature, the external circulation will be turned on, and the concentration of harmful gases in the car will be detected. The driver's mobile phone will be called or an APP pop-up window will be sent to remind him that there are people or pets left in the car; the driver can continue to maintain the in-car care mode through the mobile phone APP remote control and set the duration of the mode again. After that, when the timing time is reached again or the energy in the car is about to run out, the driver will be reminded again by phone or APP pop-up window.

[0085] Example 2

[0086] See also Figure 2 , is a flow chart of another embodiment of the vehicle intelligent power-off control method provided by the present invention. The control method is implemented by a vehicle intelligent power-off control system and is applicable to pure electric and hybrid vehicles. The control system includes a body control system (BCM), a vehicle computer (TICE), a TBOX, a mobile phone APP, an air-conditioning system, an in-vehicle occupant detection system (OMS), a vehicle control system (PCU / VCU) and a power battery management system (BMS).

[0087] In the second embodiment of the present invention, when the BCM detects that the driver leaves the vehicle and triggers the active locking action (pressing the remote control locking button or the door handle locking button), the care mode switch state of TICE is detected. If the switch state of the care mode switch state is closed, and the in-vehicle occupant monitoring system (OMS) monitors that there are living organisms left in the car, the BMS controls the whole vehicle alarm (honking + flashing lights) to remind the driver, does not perform the locking action, and the car machine pops up a window to remind that there are people / pets left in the car, and performs the first timing. If the first time threshold T1 is reached and the driver still does not take further measures, the BCM controls the air conditioner to automatically turn on the comfortable temperature setting and cut off the external circulation and start timing. When the timing time reaches the second time threshold T2, the TBOX calls the mobile phone or sends an APP pop-up window to remind the customer that there are people / pets left in the car. If the switch state of the care mode switch state is open, the BCM controls the air conditioner to automatically turn on the comfortable temperature setting and cut off the external circulation and start timing. When the timing time reaches the second time threshold T2, the TBOX calls the mobile phone or sends an APP pop-up window to remind the customer that there are people / pets left in the car.

[0088] In the second embodiment of the present invention, when the BCM detects that the driver has left the car and has not triggered the active locking action, if the OMS monitors that there are living organisms left in the car, the BMS controls the entire vehicle to alarm (honking + flashing lights) to remind the driver, and does not perform the locking action. The car machine pops up a window to remind that there are people / pets left in the car, and the first timing is performed. If the first time threshold T1 is reached and the driver still does not take further measures, the BCM controls the air conditioner to automatically turn on the comfortable temperature setting and cut off the external circulation and start timing. When the timing time reaches the second time threshold T2, the TBOX calls the mobile phone or sends an APP pop-up window to remind the customer that there are people / pets left in the car. If the switch state of the care mode switch state is on, the BCM controls the air conditioner to automatically turn on the comfortable temperature setting and cut off the external circulation and start timing. When the timing time reaches the second time threshold T2, the TBOX calls the mobile phone or sends an APP pop-up window to remind the customer that there are people / pets left in the car.

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

[0090] In the second embodiment of the present invention, when the BCM detects that the driver has left the vehicle and triggers the active vehicle locking action (pressing the remote control or door handle lock button), the vehicle occupant monitoring system (OMS) monitors whether there are living organisms (people / pets) left in the vehicle. If there are no living organisms left in the vehicle, the OMS sends a signal to the BCM, the BCM controls the vehicle to lock and power off, and the PCU / VCU controls the high voltage to power off.

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

[0092] In the second embodiment of the present invention, the driver can remotely turn on the in-car care mode through the in-car computer or mobile phone APP, and set the duration of the mode (i.e., the second timing time threshold); when the in-car care mode is turned on and the second timing time threshold T2 is not reached, if the OMS detects that there are people or pets in the car, the BCM does not control the whole vehicle to power off, and keeps the air conditioner set at a comfortable temperature, turns on the external circulation, and detects the concentration of harmful gases in the car. If the in-car care mode is turned on and the second timing time threshold T2 is reached, if the OMS detects that there are people or pets in the car, the BCM does not control the whole vehicle to power off, keeps the air conditioner set at a comfortable temperature, turns on the external circulation, and detects the concentration of harmful gases in the car, the car computer calls the driver's mobile phone through TBOX or sends an APP pop-up window to remind the customer that there are people or pets left in the car; the driver can remotely control the in-car care mode and set the mode and maintain the second timing time threshold T2 through the mobile phone APP, and call or APP pop-up window to remind the driver again after the second timing time threshold T2 is reached again or the energy in the car is about to run out.
