Description
Technical Field
The invention belongs to the technical field of power management, and particularly relates to a parking power management method and system.
Background
At present, the on-board operating system is generally upgraded by OTA, the on-board vehicle system is generally upgraded by pushing an OTA upgrade package through a cloud when a driver starts an automobile or runs, the system resources occupied by the upgrade are many, the time is long, the probability of system blockage is increased, and the user experience is poor. With the development of a vehicle-mounted video entertainment domain, the functions of vehicle-mounted software are more and more complex and diversified, and at this time, mobile phone housekeeping software like a mobile phone is required to perform system optimization.
For example when the high in the clouds has new OTA upgrade package, can send the car end through the mode of propelling movement, if the user has started the car, can receive this propelling movement, the car end downloads OTA upgrade package from the high in the clouds, then triggers the inside upgrading flow of android system: checking a packet, decompressing the packet, upgrading, waiting for restarting next time, wherein a general power management state machine of the existing vehicle machine is shown in figure 1: scheme 1: when a user starts the computer for the first time, the computer is in cold start, the computer enters a false start state from shutdown, and the screen is turned off at the moment; and (2) a flow scheme: the last time, the vehicle is stopped to enter the dormancy, and the next time, the vehicle is started from the dormancy to enter a false start state; and (3) a flow path: a user opens a vehicle door to get on the vehicle, plays the starting animation, and after the starting animation is played, the vehicle machine enters a running state; and (4) a flow chart: when the user dials the ACC OFF gear, the screen of the vehicle machine is turned OFF, and the vehicle machine enters a false shutdown state; and (5) a flow chart: after the MCU judges that the CAN network is not active, entering a dormant state from a false power-off state; and (6) a flow path: under special conditions, the power-off state is directly entered from a false power-off state, such as monitoring that the storage battery is running out of power or upgrading the OTA.
