In order to make the aforementioned objects, features and advantages of the embodiments of the present invention more comprehensible, specific embodiments accompanied with figures are described in detail below.
Referring to fig. 1, a schematic structural diagram of an in-vehicle power management device in an embodiment of the present invention is provided. Fig. 2 is a schematic diagram illustrating a connection between an onboard power management device and an automotive fuse box according to an embodiment of the invention. The following describes the in-vehicle power management device with reference to fig. 1 and 2.
In a specific implementation, the in-vehicle power management device 10 may include a ground interface 11, a first interface 12, a second interface 13, and a controller 14. The ground wire port 11 is connected to a ground wire port 21 of the automobile fuse box 20 and grounded. The first interface 12 is connected to an ACC power supply port 22 of the automobile fuse box 20. The second interface 13 is connected to a normally-powered charge port 23(VBAT) of the automobile fuse box 20. The constant-current power supply port 23 can continuously supply power, and can continuously output 12V voltage for example. It can be understood that the voltage output by the normal power supply port 23 may also be other values according to the actual vehicle scene application requirements. When the vehicle is in a key-OFF state or the vehicle key is turned to the ACC OFF gear, the ACC power-take port 22 is not powered, and the output voltage of the ACC power-take port 22 is 0V at this time. When the vehicle key is turned to the ACC ON position or ignited, the ACC power-take port 22 supplies power, and the output voltage of the ACC power-take port 22 is a preset voltage. When the ACC power takeoff 22 supplies power, the input voltage of the first interface 12 is a preset voltage, for example, the preset voltage is 12V. When the ACC power supply port 22 is not powered, the input voltage of the first interface 12 is 0V.
In a specific implementation, the controller 14 may obtain an input voltage of the first interface 12, and when the input voltage of the first interface 12 is 0V, it indicates that the vehicle is in a flameout state, and according to the input voltage of the first interface 12 and a type of the electrical equipment, reduce power consumption of the electrical equipment coupled to the vehicle-mounted power management apparatus 10 to reduce power consumption of the electrical equipment.
In a specific implementation, the controller 14 may be a Power Management Unit (PMU), a Central Processing Unit (CPU), or a Micro Controller Unit (MCU), where the MCU is also called a single-chip microcomputer. In the specific implementation, the power consumption of the electric equipment is adjusted in different ways according to the type of the electric equipment when the vehicle is in a flameout state. The electric equipment can comprise one or more of a rear-mounted vehicle entertainment system, a vehicle interior lighting lamp, a camera, a radio, Bluetooth equipment, a vehicle event data recorder and the like. It is understood that the powered device may be other devices on the vehicle, which is not illustrated herein.
In an embodiment of the invention, when the input voltage of the first interface 12 is 0V, the controller 14 may adjust an electrical device coupled to the vehicle-mounted power management apparatus 10 to enter a low power consumption state, where power consumption of the electrical device in the low power consumption state is less than power consumption of the electrical device in a normal operating state.
For example, the electric device is a bluetooth device, and when the input voltage of the first interface 12 is 0V, the controller 14 reduces the broadcast frequency of the bluetooth device to reduce the power consumption of the electric device, so that the power consumption of the bluetooth device can be considered while the bluetooth device can normally operate.
For another example, the electric device is a camera, and when the voltage of the first interface 12 is 0V, the controller 14 reduces the resolution of an image acquired by the camera, or adjusts the current shooting mode of the camera to a photo mode, or adjusts the camera to enter another working mode, so as to reduce the power consumption of the camera, and further reduce the power consumption of the electric device.
For another example, when the electric device is an interior lamp, the controller 14 reduces the brightness of the interior lamp to reduce the power consumption of the interior lamp when the voltage of the first interface 12 is 0V.
In another embodiment of the present invention, when the input voltage of the first interface 12 is 0V, the controller 14 stops supplying power to the electric device coupled to the vehicle-mounted power management apparatus 10.
In another embodiment of the present invention, when the input voltage of the first interface 12 is 0V, the controller 14 turns off the electric device coupled to the vehicle-mounted power management apparatus 10.
In an implementation, the controller 14 may simultaneously adjust the power consumption of a plurality of electrical devices coupled to the in-vehicle power management apparatus 14. The controller 14 may adjust the power consumption amounts of the plurality of electric devices in the same adjustment manner, or may adjust the power consumption amounts of the plurality of electric devices in different adjustment manners for different electric devices. For example, when the input voltage of the first interface 12 is 0V and the vehicle is in a flameout state, a part of the electric devices are controlled to enter a low power consumption mode, power supply to another part of the electric devices is stopped, and the part of the electric devices is turned off. For another example, when the input voltage of the first interface 12 is 0V and the vehicle is in a flameout state, all the electric devices are controlled to enter the low power consumption mode. For another example, when the input voltage of the first interface 12 is 0V and the vehicle is in a key-off state, power supply to all the electric devices is stopped.
In specific implementation, when the vehicle is in a flameout state, that is, when the input voltage of the first interface 12 is 0V, it may be determined which electric devices in the vehicle enter the low power consumption mode, or stop supplying power to which electric devices, or turn off which electric devices according to the actual demand of the user.
In a specific implementation, the vehicle-mounted power management device 10 may further include a power supply interface (not shown in the figure) for supplying power to the external device. Because the second interface 13 of the vehicle-mounted power management device is connected with the normal power electricity taking port 23 of the automobile fuse box 20, the power supply interface can continuously supply power under the condition that the automobile storage battery has reserved electric quantity. Therefore, even if the vehicle is in a flameout state, the user can supply power to the mobile phone, the tablet or other external equipment through the power supply interface.
In order to protect the vehicle battery and avoid excessive power shortage of the vehicle battery, in the embodiment of the present invention, the controller 14 may further obtain the input voltage of the second interface 13, and when the input voltage of the second interface 13 is lower than the safety threshold, the power supply to the electric device coupled to the vehicle-mounted power management apparatus 10 may be stopped.
For example, the input voltage of the second interface 13 is 12V, and when it is detected that the input voltage of the second interface 13 is lower than 11.5V, the power supply to the electric device coupled to the vehicle-mounted power management apparatus 10 is stopped, it can be understood that the safety threshold may also be other values, and may specifically be set according to requirements of an actual application scenario.
According to the scheme, the vehicle-mounted power supply management device is adopted, the vehicle-mounted power supply management device is connected with the ACC power-taking port and the normal power-taking port on the automobile fuse box, the output voltage of the ACC power-taking port can be obtained, namely the input voltage of the first interface, so that the power consumption of the electric equipment coupled with the vehicle-mounted power supply management device is reduced according to the input voltage of the first interface and the type of the electric equipment, and the power consumption of the electric equipment is reduced. Compare prior art OBD interface and continuously supply power, can learn whether the car is currently in flame-out state through the input voltage of first interface to adjust the power consumption of consumer according to the current state of vehicle, can practice thrift the energy consumption, reduce car storage battery insufficient voltage.
The embodiment of the invention also provides a vehicle-mounted power management method which can manage any vehicle-mounted power management device provided by the embodiment of the invention. Referring to fig. 3, a flowchart of a vehicle power management method in the embodiment of the present invention is shown, which may specifically include the following steps:

In a specific implementation, the vehicle-mounted power management device may include a first interface, and the first interface is connected with an ACC power supply of the automobile fuse box. The input voltage of the first interface of the vehicle-mounted power management device can be acquired.
When the vehicle is in a flameout state or the vehicle key is screwed to an ACC OFF gear, the ACC power taking port is not powered, and the output voltage of the ACC power taking port is 0V at the moment. When a vehicle key is screwed to an ACC ON gear or is ignited, the ACC power taking port supplies power, and the output voltage of the ACC power taking port is preset voltage. When the ACC power-taking port supplies power, the input voltage of the first interface is a preset voltage, for example, the preset voltage is 12V. When the ACC power-taking port is not powered, the input voltage of the first interface is 0V.
And step 32, reducing the power consumption of the electric equipment coupled with the vehicle-mounted power management device according to the input voltage of the first interface and the type of the electric equipment.
In a specific implementation, after the input voltage of the first interface is acquired, the power consumption of the electric equipment coupled with the vehicle-mounted power management device may be reduced according to the input voltage of the first interface and the type of the electric equipment.
In the embodiment of the invention, when the input voltage of the first interface is 0V, the automobile is characterized to be in a flameout state.

In an embodiment of the present invention, when the input voltage of the first interface is 0V, the electrical device coupled to the vehicle power management apparatus is adjusted to enter a low power consumption state.
For example, the electric equipment is bluetooth equipment, and when the input voltage of first interface was 0V, reduced bluetooth equipment's broadcast frequency to can compromise bluetooth equipment's consumption when guaranteeing that bluetooth equipment can normally work.
For another example, the electric device is a camera, and when the voltage of the first interface is 0V, the resolution of an image acquired by the camera is reduced, or the current shooting mode of the camera is adjusted to a photo mode, or the camera is adjusted to enter other working modes, so as to reduce the power consumption of the camera.
For another example, when the electrical device is an interior lighting lamp, and the voltage of the first interface is 0V, the controller reduces the brightness of the interior lighting lamp to reduce the power consumption of the interior lighting lamp.
In another embodiment of the present invention, when the input voltage of the first interface is 0V, the power supply to the electric device coupled to the vehicle-mounted power management apparatus is stopped.

In an implementation, the controller may adjust the power consumption of a plurality of electrical devices coupled to the in-vehicle power management apparatus at the same time. For example, when the input voltage of the first interface is 0V and the vehicle is in a flameout state, a part of the electric devices are controlled to enter a low power consumption mode, power supply to another part of the electric devices is stopped, and the part of the electric devices is turned off. For another example, when the input voltage of the first interface is 0V and the vehicle is in a flameout state, all the electric devices are controlled to enter the low power consumption mode. For another example, when the input voltage of the first interface is 0V and the vehicle is in a flameout state, power supply to all the electric devices is stopped.
