In the embodiment of the present invention, a certain time period is preset as the standby time period. The standby time period may be set according to parameters such as a use time period and a use frequency of the vehicle, which may be a period of 24 hours, and a continuous time or a plurality of continuous times within 24 hours is set as the standby time period. And time units such as months and quarters can be used as periods, and one or more continuous time can be set as the standby time period, so that the beneficial effects of the invention are not influenced.
As an example, with 24 hours a day as a cycle, 6:00 to night 22:00 as the standby period. And judging whether the current time is in a standby time period of 6:00-22:00, if so, starting the standby function of the vehicle-mounted host.

An RTC timing module (Real-Time-Clock) is arranged for realizing the timing function, so that reliable Time is provided for the vehicle-mounted system. In an embodiment of the present invention, the RTC timing module is configured to: when the count-down reaches a predetermined standby start time point, for example, 6:00 in the above embodiment, a standby start command is issued. When the controller receives the standby starting instruction, the controller judges that the standby time period is about to enter the preset standby time period from the current time point, and starts the standby function of the vehicle-mounted host in the standby time period. When the time is counted down to a preset standby end time point, for example, 22:00 in the above embodiment, the standby end instruction is issued, so that the controller determines that the standby time period will not be within the preset standby time period from the current time point when receiving the standby end instruction, and turns off the in-vehicle host standby function.

And if the current charging function state of the power battery is a state capable of charging a storage battery of a vehicle, controlling the storage battery to supply power to the vehicle-mounted host in a standby mode and controlling the vehicle-mounted host in the standby mode.
The charge function state of the power battery includes a state in which the storage battery of the vehicle can be charged and a state in which the storage battery of the vehicle is prohibited from being charged; and when the power battery is in a state of being capable of charging the storage battery, the storage battery is charged according to the charging requirement of the storage battery.
Specifically, the in-vehicle host standby function is started after it is determined that the current time is within a preset standby period. And then after the whole vehicle is powered OFF, namely when the vehicle is in a KL15 OFF state, acquiring the current charging function state of the power battery of the vehicle. And if the current charging function state of the power battery is a state capable of charging a storage battery of the vehicle, controlling the vehicle-mounted host machine to be in a standby state.
And in the process that the vehicle-mounted host is in the standby state, the storage battery supplies power to the vehicle-mounted host in a standby mode, so that the power consumption requirement in the standby state of the vehicle-mounted host is met. In the process, if the electric quantity of the storage battery is insufficient, the storage battery can be charged by the power battery by sending the charging requirement of the storage battery to the power battery, so that the power consumption requirement of the storage battery is ensured.
It should be noted that, in the embodiment of the present invention, the steps S22 and S23 correspond to the steps S11 and S12 in the first embodiment one to one, and the execution principle and the beneficial effect of the two steps are the same, which is not described herein again.
