In this embodiment, prompting and/or sending the power-off prompting message may be understood as prompting and sending the power-off prompting message in one embodiment. In another embodiment, a prompt is provided to prompt for information. In yet another embodiment, a power down prompt message is sent.
In this embodiment, the vehicle 100 includes a central control display 20 for prompting the power-off prompting information, including:
the control center display screen 20 prompts the power-off prompting information.
The power-off control method of the above embodiment can be realized by the controller 10 of the present embodiment. The controller 10 is used for controlling the central control display screen 20 to prompt the power-off prompting information. In this way, the user can timely obtain the prompt message of the vehicle 100 about to be powered off through the central control display screen 20, so that corresponding processing can be performed.
Specifically, in one embodiment, when the timing duration reaches a second preset duration, the central control display 20 may have a pop-up window, and a power-off prompt message appears in the pop-up window. In this embodiment, the power-off prompt message includes a remaining time period for executing power-off and a prompt for canceling power-off. Referring to fig. 3, fig. 3 shows the power-off prompt information prompted by the central control display screen 20, the power-off prompt information is displayed by a pop-up window, the remaining time of the pop-up window display is 40 minutes, and "power-off command is displayed, whether to cancel? "," yes "and" no ". The user can select an operation on the popup. In other embodiments, the power-off prompt message is also broadcasted on the central control display 20 by voice prompt, which is not limited herein.
In this embodiment, the sending the power-off prompt message includes:
and sending the power-off prompting information to the preset terminal 200, so that the preset terminal 200 prompts the power-off prompting information.
The power-off control method of the above embodiment can be realized by the controller 10 of the present embodiment. The controller 10 is configured to send a power-off prompting message to the preset terminal 200, so that the preset terminal 200 prompts the power-off prompting message. In this way, the user can timely obtain the power-off prompt information that the vehicle 100 is to be powered off through the preset terminal 200, so that corresponding processing can be performed.
Specifically, under the condition that the timing duration reaches the second preset duration, the first controller 12 pushes the power-off prompt information to the preset terminal 200, and after the preset terminal 200 receives the push, the APP of the preset terminal 200 displays the remaining duration of the power-off instruction and cancels the prompt of the power-off instruction. Referring to fig. 4, the default terminal 200 is a mobile phone, and after receiving the push of the power-off command, the mobile phone displays that the remaining time is 40 minutes, and displays "power-off command, whether to cancel? "," yes "and" no ". In other embodiments, the power-off prompt message is also broadcasted in the preset terminal 200 in a voice prompt manner, which is not limited herein.
In this embodiment, referring to fig. 5, the power-down control method includes:
in step S90, the timing duration is cleared and the power-off is cancelled when the power-off cancellation instruction is received between the second preset duration and the first preset duration.
The power-off control method of the above embodiment can be implemented by the vehicle 100 of the present embodiment. Here, step S90 may be implemented by the controller 10. The controller 10 is configured to clear the timing duration and cancel the power-off when the power-off cancellation instruction is received between the second preset duration and the first preset duration. Thus, under the condition that the vehicle 100 still needs to be used, the user can timely prevent the vehicle 100 from automatically powering off, and the user experience is good.
Specifically, between the second preset duration and the first preset duration, it can be understood that the timed duration is also within the countdown duration. That is to say, within the countdown duration, if the APP of the central control display 20 or the preset terminal 200 receives the power-off cancellation instruction, it indicates that at this time, the user selects the option of canceling the power-off through the APP of the central control display 20 or the preset terminal 200. The first controller 12 may then clear the timed length and cancel the power down command. It should be noted that, after the first controller 12 clears the timer period and receives the power-off cancellation command, the detection of the state of the vehicle 100 is continued again.
In this embodiment, if the power-off cancellation instruction is not received between the second preset time and the first preset time, that is, the user does not select the power-off cancellation instruction through the central control display 20 or the APP of the preset terminal 200. In this case, in the case where the counted time period reaches the first preset time period, that is, the countdown is ended, at which time the first controller 12 issues a request for a power-off command and the second controller 14 controls the power-off of the vehicle 100.
In this embodiment, referring to fig. 6, the power-down control method includes:
when the start automatic power-off function command is received, the process proceeds to the step of acquiring the state of the vehicle 100.
The power-off control method of the above embodiment can be realized by the controller 10 of the present embodiment. The controller 10 is configured to start acquiring the state of the vehicle 100 when receiving an instruction to start the automatic power-off function. Thus, the user can flexibly turn on and off the automatic power-off function of the vehicle 100, and various requirements of the user are met.
Specifically, the automatic power-off function command may be input through the central display 20 of the vehicle 100, or through the preset terminal 200, or through a key of the vehicle 100, which is not limited herein and may be set according to actual conditions.
In one embodiment, referring to FIG. 6, vehicle 100 includes an input assembly 30 through which an automatic power down function command may be input, input assembly 30 including, but not limited to, input mechanical keys, input touch keys, and the like. In the case where the user turns off the automatic power-off function of the vehicle 100 through the input assembly 30, the controller 10 does not acquire the state of the vehicle 100.
Referring to fig. 7, the present disclosure also provides a computer-readable storage medium 300. The computer-readable storage medium 300 stores a computer program. The computer program, when executed by the processor 310, implements the power down control method of any of the above embodiments.
For example, referring to fig. 1 and 7, when executed by the processor 310, the computer program implements the following steps:
step S20, acquiring the state of the vehicle 100;
step S40, when the state of the vehicle 100 meets the preset condition, timing is started according to a first preset time length;
step S60, prompting and/or sending a power-off prompting message when the timing duration reaches a second preset duration, wherein the second preset duration is less than the first preset duration;
and step S80, controlling the vehicle 100 to power off under the condition that the power off cancellation instruction is not received between the second preset time length and the first preset time length and the timing time length reaches the first preset time length.
In the computer-readable storage medium 300 of the above embodiment, when the state of the vehicle 100 satisfies the preset condition, the power-off prompting message is prompted and/or sent, and when the power-off cancelling instruction is not received within a certain time period and the timing time period reaches the first preset time period, the power-off of the vehicle 100 is controlled, so that the problem that the driving range of the vehicle 100 is reduced when the user forgets to power off the vehicle 100 can be prevented.
