The controller 50 continuously performs a monitoring operation consisting of a series of processing operations such as an analysis operation of data, a data storage operation, and a notification operation while the vehicle is running, while the monitoring operation is selectively performed when the vehicle is not running. .

That is, the controller 50 may perform the monitoring operation only when a person or an object approaches when the vehicle is not running or change the monitoring operation condition (or operating power supply condition) according to the amount of power of the vehicle. In this case, the monitoring operation condition is a condition for varying the execution period of the monitoring operation and the type of the operation (for example, an analysis operation, a data storage operation, and a notification operation).

When the data storage is requested by the user (that is, a data storage command is input from the user interface unit 40), the controller 50 immediately performs a data storage operation in response thereto.

In addition, even when the user requests to copy specific monitoring data to the external memory device 91, the controller 50 reads the monitoring data from the data storage unit 60 in response to the external memory device 91. You can also save it to.

That is, when the amount of power of the vehicle is 'high', the monitoring operation is activated every 1 minute, in case of 'medium', the monitoring operation is activated every 5 minutes. It is assumed that the user notification operation is performed without the data storage operation.

First, when the vehicle in which the vehicle is installed is not running (S31), the power saving mode is set (S32), and the current amount of power of the vehicle is checked (S33).

As a result of checking in step S33, when the amount of power of the vehicle is 'phase', the monitoring data is obtained and analyzed at intervals of 1 minute (S34), and if it is 'medium', monitoring data is obtained and analyzed at intervals of 5 minutes (S35).

As a result of the analysis of step S34 or S35, if an abnormal vehicle state change has occurred (S36), a message for notifying this is sent to the user terminal 83 registered in advance (S37), and the monitoring data for a predetermined amount of time before that time point. It permanently stores (S38).

On the other hand, if the amount of power is 'low' as a result of checking in step S33, the monitoring data is acquired and analyzed every 10 minutes (S39), and if an abnormal vehicle state change occurs (S40), only whether the abnormal vehicle state change occurs to the user After notifying, the operation ends (S41).

That is, the vehicle state monitoring method of FIG. 5 minimizes power consumption for the monitoring operation by sequentially adjusting the monitoring operation conditions of the vehicle according to the amount of power of the vehicle.

In the above embodiment, the case in which the monitoring operation condition is divided into three stages according to the remaining amount of power of the vehicle has been described.
