Description
Technical Field
The invention relates to the technical field of vehicles, in particular to a vehicle power supply control method, a controller and a vehicle.
Background
At present, when a controller of a vehicle is powered on, a clear electrical signal is required, such as a CAN (controller area network) bus signal or a switch level signal. When a controller of the vehicle is in a power-down state, part of the functions of the vehicle may fail.
However, as the demand for vehicle performance by users increases, users desire to implement functions such as vehicle theft prevention or OTA (Over-the-Air Technology) upgrade of controllers while the vehicle is in a parked state. For the anti-theft of the vehicle, it is necessary to keep the controller of the vehicle in an operating state all the time, so that the static power consumption of the vehicle is high. For the OTA upgrade of the controller, since the OTA upgrade needs to be restarted, the user needs to intervene to power down or power up the controller.
It can be seen that the controllers of existing vehicles cannot be powered up or down autonomously.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
First embodiment
As shown in fig. 1, a vehicle power supply control method includes the steps of:
And 103, controlling the controller to be powered on if the power-on trigger condition is detected to be met.
The controller in the embodiment of the invention can be a Vehicle Control Unit (VCU), and the controller is an assembly controller of a hybrid power or pure electric Vehicle power system and is responsible for coordinating the work of each component such as an engine, a driving motor, a gearbox, a power battery and the like. Embodiments of the present invention encompass power control of the controller, that is, control of power up or power down of the controller.
As shown in fig. 2, the hardware modules of the controller 20 may include a power supply chip 21, a single chip 22, and other functional circuits 23. The power chip 21 may provide a working power supply for the single chip 22 and the other functional circuits 23, and the single chip 22 may perform communication interaction with the power chip 21 through a level signal or other manners, such as performing operations of function diagnosis, powering down a controller, powering up the controller, or setting a register in the power chip 21. The switch signal or the bus signal may be accessed from outside of the controller 20 to provide the power-on command and/or the power-off command for the power chip 21.
Each step of the embodiment of the present invention is specifically described below with reference to a hardware module of the controller.
Before the controller of the vehicle is powered down, the single chip 22 may determine whether there is a power-up requirement after the controller is powered down. And judging whether the controller has a power-on requirement after power-off can be judged by acquiring the working state of the controller. For example, whether the controller is performing or needs to perform an OTA upgrade, whether the controller needs to be repeatedly activated to monitor the vehicle status, and so on.
If the single chip microcomputer 22 determines that the controller has a power-on requirement after powering off, the single chip microcomputer 22 may preset a power-on trigger condition before powering off the controller. In this way, after the controller is powered off, if it is detected that the power-on trigger condition is satisfied, the power supply chip 21 is controlled to be powered on, thereby realizing the autonomous power-on of the controller.
If the single chip microcomputer 22 judges that the controller does not have a power-on demand after power-off, the single chip microcomputer 22 can send a power-off instruction to control the power supply chip 21 to power off, so that power off of the controller is achieved.
In the embodiment of the invention, before the controller is powered off, whether the controller has a power-on requirement after the controller is powered off is judged, so that the controller is powered on autonomously. On one hand, the controller can be automatically electrified, so that manual intervention of a driver is not needed, and the automation degree of the vehicle can be improved; on the other hand, the controller can be automatically powered on, and the controller does not need to be in a working state all the time, so that the static power consumption of the vehicle can be reduced.
On the basis of the above embodiments of the invention, the following description is given by taking the controller performing or needing system upgrade (for example, OTA upgrade) as the controller having a power-on requirement.
Optionally, the step of determining whether there is a power-on demand after the controller is powered off includes:
judging whether the controller is in progress or needs to be upgraded;
and if the controller is in progress or needs to be upgraded, judging that the controller has a power-on requirement after power-off.
Further, before the step of controlling the controller to be powered on, the method further comprises:
and if the controller system is detected to be upgraded, controlling the controller to power off.
Generally, after the controller completes the system upgrade, the controller needs to be restarted to ensure that the system upgrade is valid. Conventionally, after the controller completes the system upgrade, the driver is required to power on the vehicle again to complete the restart operation of the controller.
After the power supply control method provided by the embodiment of the invention is adopted, the system upgrade of the controller can be completely and automatically realized, and a driver only needs to allow the upgrade by one key, so that the controller can be automatically electrified and restarted after the system upgrade is finished without manual intervention.
Optionally, after the controller is powered off, if an external power-on trigger signal is received, the controller is controlled to be powered on.
In the embodiment of the invention, if the controller receives an external power-on trigger signal before the preset power-on trigger condition is met, the controller can immediately enter a power-on state. Thereby enabling the controller to respond to power-up requirements in real time.
Second embodiment
As shown in fig. 3, a vehicle power supply control method includes the steps of:
And step 304, controlling the controller to be powered on.
In this embodiment of the present invention, the power-on triggering condition may be a time condition, that is, the first preset time in step 301. As such, the hardware modules of the controller 20 may also include a timer 24. The timer 24 may be disposed in the manner as shown in fig. 2, that is, the timer 24 is integrated inside the power supply chip 21; in addition, the timer 24 may also be a part of the controller system circuit, which is not limited in the embodiment of the present invention.
The timer 24 can be set by the single chip 22, and the output signal of the timer 24 can trigger the power supply chip 21 to be powered on, so that the controller is powered on again.
Specifically, if the single chip microcomputer 22 determines that there is an autonomous power-on demand after the controller is powered off, the single chip microcomputer 22 may set the timer 24 in the power supply chip 21 before the single chip microcomputer 22 sends a power-off instruction to the power supply chip 21. After the power supply chip 21 receives a power-off instruction from the single chip 22, each power supply output channel is closed, and at this time, the timer 24 starts to time. When the timer 24 finishes timing, the timer 24 outputs an internal trigger signal to the power chip 21, the power chip 21 supplies power to each functional circuit again, namely, the controller is powered on, and the controller enters a normal working mode after being powered on.
In the embodiment of the invention, when the controller has a power-on requirement, the power-on trigger condition is set as the first preset time, so that the controller can be powered on automatically when the first preset time is reached from the power-off moment of the controller. On one hand, the controller can realize the automatic power-on at the set time, so that the manual intervention of a driver is not needed, and the automation degree of the vehicle can be improved; on the other hand, the controller can realize the autonomous power-on at the set time, and the controller does not need to be in a working state all the time, so that the static power consumption of the vehicle can be reduced.
It should be noted that the execution order of step 301 and step 302 is not limited, that is, step 301 and step 302 do not have a logical order. In addition, the execution times of step 302 are not limited, and the power-on trigger condition in step 302 may be set according to specific situations.
All the optional implementation manners in the first embodiment can be implemented by combining the embodiments of the present invention, and can achieve the same beneficial effects, and in order to avoid repetition, the embodiments of the present invention are not described in detail herein.
Third embodiment
As shown in fig. 4, a vehicle power supply control method includes the steps of:
And step 403, controlling the controller to be powered on if the power-on trigger condition is detected to be met.
And step 404, detecting whether a preset power-off trigger condition is met.
And 405, controlling the controller to power off if the power off triggering condition is met.
In steps 401 to 403, reference may be made to the related descriptions in the first embodiment and the second embodiment, and the same beneficial effects can be achieved.
In steps 404 to 405, after the controller is powered on autonomously, if it is detected that a preset power-off trigger condition is met, the controller may be controlled to be powered off.
Therefore, the embodiment of the invention can realize the autonomous power-on and the autonomous power-off of the controller. Therefore, the automation degree of the vehicle can be further improved, and the static power consumption of the vehicle can be further reduced.
It should be noted that steps 401 to 405 may be executed circularly, that is, after step 403 is executed and before step 405 is executed, step 401 may be executed again. Therefore, the embodiment of the invention can realize the cyclic autonomous power-on and autonomous power-off of the controller.
Optionally, before the step of detecting whether the preset power-on trigger condition is met, the method further includes:
setting the power-on trigger condition as a first preset time;
the step of detecting whether the preset power-on trigger condition is met comprises the following steps:
and when the controller is started at the power-off moment and the first preset time is reached, judging that the power-on trigger condition is met.
Optionally, before the step of detecting whether the preset power-off trigger condition is met, the method further includes:
setting the power-off trigger condition as a second preset time;
the step of detecting whether a preset power-off trigger condition is met comprises the following steps:
and when the controller is started to be powered on and the second preset time is reached, determining that the power-off triggering condition is met.
It should be noted that, for the case that the power-on trigger condition and the power-off trigger condition are time conditions, the determination of the power-on trigger condition and the determination of the power-off trigger condition may be performed by the timer 24 shown in fig. 2, and the working principle of the timer 24 may be the same as that in the second embodiment, and is not described again to avoid repetition.
For example, the controller has completed a system upgrade, requiring a reboot of the controller. First, if the completion of the upgrading of the controller system is detected, the controller can be controlled to be powered off. Secondly, after the controller is powered off, if it is detected that a preset power-on trigger condition (e.g., a time condition) is satisfied, the controller can be controlled to be powered on, and at this time, the restart of the controller is completed. Finally, to further reduce the static power consumption of the vehicle, after the controller is powered on, if it is detected that a preset power-off triggering condition (e.g., a time condition) is satisfied, the controller may be controlled to be powered off.
For example, based on the anti-theft requirements of the vehicle, the controller needs to be periodically activated to monitor the vehicle state while the vehicle is in a key-off state. The controller can be enabled to automatically power up again at intervals after power down, and automatically power down again at intervals after power up, and the process is cycled.
