Description

Technical Field

[0001] This invention relates to the field of intelligent driving technology, and more specifically, to a vehicle monitoring method, a vehicle, and a storage medium. Background Technology

[0002] With the development of new energy vehicles, more and more people are paying attention to the battery issues of new energy vehicles. In order to prevent the batteries of new energy vehicles from running out of power, corresponding delay operation strategies have been implemented in various controllers of the vehicle. This not only meets the need to retain some functions after power is off, but also reduces the risk of the vehicle battery being continuously depleted. The integrated brake control assembly (IBC) can also meet the above functions.

[0003] However, in practical applications, the delayed operation strategy of the integrated brake control assembly that integrates the electronic parking brake system (EPB) cannot meet the above two requirements. Therefore, the electronic parking brake system may fail to function after power is off, resulting in the phenomenon of rolling backward.

[0004] There is currently no effective solution to the above problems. Summary of the Invention

[0005] This invention provides a vehicle monitoring method, a vehicle, and a storage medium to at least solve the technical problem in the prior art where the electronic parking brake system cannot function after power is off, resulting in a rollover phenomenon.

[0007] Optionally, the vehicle monitoring method further includes: determining the ignition switch state of the vehicle; in response to the ignition switch state being in the off state, determining a target time length, wherein the target time length is the duration for which the ignition switch state is in the off state; comparing the target time length with a preset time length; and in response to the target time length being greater than the preset time length, determining the vehicle's driving state as the off state.

[0008] Optionally, the vehicle monitoring method further includes: re-determining the ignition switch state in response to the target time length being less than or equal to the preset time length.

[0009] Optionally, the vehicle monitoring method further includes: in response to the vehicle being in a turned-off state, controlling the vehicle's message sending function to be turned off.

[0011] Optionally, the vehicle monitoring method further includes: in response to the switch being in the pulled-up state, activating the network communication function and the electronic control unit, and reacquiring the target time length.

[0012] Optionally, the vehicle monitoring method further includes: in response to the switch state being in a released state, controlling the activation of the target function of the electronic parking brake system.

[0013] According to one embodiment of the present invention, a vehicle monitoring device is also provided, comprising: a first determining module for determining the driving state of the vehicle; a first control module for controlling the network communication function and electronic control function of the vehicle to be turned off in response to the driving state being an off state; a second determining module for determining the on / off state of the electronic parking brake system of the vehicle; and a second control module for controlling the network communication function to remain off and controlling the electronic control function to be turned on in response to the on / off state being a released state.

[0014] According to one embodiment of the present invention, a vehicle is also provided, including a memory and a processor, wherein the memory stores a computer program and the processor is configured to run the computer program to perform the vehicle monitoring method described in any of the preceding claims.

[0015] According to one embodiment of the present invention, a non-volatile storage medium is also provided, wherein a computer program is stored in the non-volatile storage medium, wherein the computer program is configured to execute the vehicle monitoring method described in any of the above embodiments when running.

[0016] In this embodiment of the invention, the vehicle's driving state is determined, and in response to the driving state being off, the vehicle's network communication function and electronic control unit are turned off. The on / off state of the vehicle's electronic parking brake system is determined, achieving the purpose of keeping the network communication function off and controlling the electronic control unit to turn on in response to the on / off state being released. This achieves the technical effect that the electronic parking brake system can monitor the parking state after the vehicle is turned off, thereby solving the technical problem in the prior art where the electronic parking brake system cannot function after power is off, resulting in the phenomenon of rolling backward.

[0029] Figure 1 This is a flowchart of a vehicle monitoring method according to one embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0030] Step S102: Determine the vehicle's driving status.

[0031] Optionally, the execution subject in this embodiment is a vehicle monitoring system. It should be noted that other electronic devices and processors can also be used as execution subjects, and no further limitations are made here.

[0032] In the technical solution provided by step S102 of the present invention, the vehicle monitoring system can first determine the current driving state of the vehicle, for example, whether the vehicle is in a turned-off state or a started state.

[0033] In step S104, in response to the vehicle being in a turned-off state, the network communication function and electronic control unit of the vehicle are turned off.

[0034] In the technical solution provided by step S104 of the present invention, when the vehicle monitoring system determines that the vehicle is in a turned-off state, the network communication function and electronic control unit of the vehicle are turned off.

[0035] Optionally, the aforementioned network communication functions include communication with other modules of the vehicle, and the electronic control unit can control the integrated brake control assembly and the electronic parking brake system.

[0036] Optionally, in the prior art, after the vehicle is turned off, the vehicle's network communication function and electronic control unit will be shut down after a preset time to ensure responsiveness to the driver's operating intentions.

[0037] Step S106: Determine the on / off status of the vehicle's electronic parking brake system.

[0038] In the technical solution provided by step S106 of the present invention, when the vehicle's network communication function and electronic control function are both turned off, the on / off status of the vehicle's electronic parking brake system is detected in real time.

[0039] Optionally, when the vehicle is turned off, it is stationary, so the electronic parking brake system can be assumed to be engaged at this time to facilitate subsequent monitoring of the electronic parking brake system status.

[0040] In step S108, in response to the switch being in the released state, the network communication function is kept off, and the electronic control unit is turned on.

[0041] In the technical solution provided by step S108 of the present invention, when the switch state of the electronic parking brake system is detected to be in the released state, the integrated brake control responds to the released state of the electronic parking brake system and cannot accurately determine whether the driver intends to release the switch at this time. If the electronic parking brake system is released at this time, there may be a risk of rolling backward. Therefore, the release operation is not performed on the electronic parking control system, and the vehicle's network communication function is not required. However, since the driver has operated the switch of the electronic parking brake system, in order to avoid problems, the integrated brake control should monitor the switch state of the electronic brake system again, so the electronic control unit should be turned on again.

[0042] From the above steps S102 to S108, it can be seen that in this invention, as... Figure 2 As shown, by determining the vehicle's driving state, and responding to the vehicle being in a turned-off state, the vehicle's network communication function and electronic control unit are turned off, and the on / off state of the vehicle's electronic parking brake system is determined. This achieves the goal of keeping the network communication function off and controlling the electronic control unit to turn on when the on / off state is in an engaged state. This realizes the technical effect that the electronic parking brake system can monitor the parking status after the vehicle is turned off, and thus solves the technical problem in the prior art where the electronic parking brake system cannot function after power is off, resulting in the phenomenon of rolling backward.

[0043] The method described in this embodiment will now be described in further detail.

[0044] As an optional implementation, the ignition switch state of the vehicle is determined; in response to the ignition switch state being in the off state, a target time length is determined, wherein the target time length is the time length during which the ignition switch state is in the off state; the target time length is compared with a preset time length; in response to the target time length being greater than the preset time length, the vehicle's driving state is determined to be in the off state.

[0045] In this embodiment, determining the vehicle's driving state includes the following steps: first, determining the vehicle's ignition switch state; when the ignition switch state is closed, it indicates that the vehicle is not in motion; then, it is necessary to further determine the duration for which the vehicle's ignition switch state is closed; then, it is determined whether the vehicle's time in the off state exceeds a preset time; when the vehicle's time in the off state exceeds the preset time, the vehicle's driving state is determined to be off.

[0046] Optionally, the above preset time can be determined according to the actual application or legal regulations, and different preset times can be determined for different vehicle models.

[0047] As an optional implementation, the ignition switch state is redefined in response to the target time length being less than or equal to the preset time length.

[0048] In this embodiment, the time the vehicle remains in the off state is compared with a preset time. If the time the vehicle remains off does not exceed the preset time, the ignition switch of the vehicle is not kept in the off state. That is, the driver may have the intention to start the engine at this time. Therefore, the state of the ignition switch should continue to be monitored. When the state of the ignition switch is detected to be off again, the target time length is re-determined.

[0049] As an optional implementation, the vehicle's message transmission function is turned off in response to the vehicle being in a turned-off driving state.

[0050] In this embodiment, when the vehicle is detected to be in a turned-off state, the vehicle monitoring system should control the vehicle's network communication function to be turned off, that is, control the message sending function between the various functional modules of the vehicle.

[0051] As an optional implementation, in response to the engine being turned off while driving, the target functions of the electronic parking brake system are turned off, including: high-temperature re-clamping function, hill-drift re-clamping function, and static switch parking function.

[0052] In this embodiment, when the vehicle is detected to be in a turned-off state, the vehicle monitoring system should also control the vehicle's electronic control unit to shut down, that is, control the target function of the electronic parking brake system to shut down.

[0053] Specifically, the aforementioned target functions include high-temperature re-clamping function, slope re-clamping function, and static parking switch function. Among them, the high-temperature re-clamping function can prevent the vehicle from rolling backward due to the brake pads softening due to excessive heat. Therefore, when the temperature exceeds the preset temperature, the electronic parking brake system can be controlled to perform a clamping operation again to avoid the risk of rolling backward. The slope re-clamping function can prevent the risk of rolling backward when the vehicle is on a slope. When the vehicle detects that the wheels of the vehicle parked on the slope are moving, the electronic parking brake system can be controlled to perform a clamping operation again to avoid the risk of rolling backward.

[0054] As an optional implementation, in response to the switch being in the pulled-up state, the network communication function and electronic control unit are activated, and the target time length is reacquired.

[0055] In this embodiment, when determining the on / off state of the vehicle's electronic parking brake system, if the switch state is detected as engaged, the integrated brake control assembly assumes the driver intends to engage the switch. Therefore, the vehicle monitoring system activates the network communication function. At this time, the integrated brake control assembly activates the network communication function with other controllers and the electronic control unit. Thus, the electronic control unit can enable the electronic parking brake system to perform the clamping operation again. Since the vehicle is still in a turned-off state, the target time length should be acquired again to restart the timing. When the target time length exceeds the preset time length, the network communication function and the electronic control unit are deactivated again.

[0056] As an optional implementation, the target function of the electronic parking brake system is activated in response to the switch being in the released state.

[0057] In this embodiment, when the electronic parking brake system is detected to be in the released state, since the driver has operated the electronic parking brake system switch, in order to avoid problems, the integrated brake control should monitor the electronic parking brake system's switch state again. Therefore, the electronic control unit should be turned on again, and the target functions of the electronic parking brake system should be restored, namely, high-temperature re-clamping function, hill-drift re-clamping function, and static switch parking function.
