The driving of the engine 15 of the vehicle 1 may be stopped based on the engine 15 stop signal transmitted by the control unit 100, and when the driving of the engine 15 is stopped, the battery 80 of the vehicle 1 does not charge

As described above, when the charge amount of the battery 80 detected by the controller 100 is less than a predetermined value, the engine 15 of the vehicle 1 must be driven to charge the battery 80 . However, when the temperature of the engine exhaust heat recovery device 10 is higher than a predetermined temperature, the engine 15 of the vehicle 1 cannot be driven because the risk of fire caused by objects located around the vehicle 1 is high. The controller 100 may transmit a warning control signal to the driver of the vehicle 1 (480).

The display unit 350 may display at least one of the temperature of the exhaust heat recovery device of the engine 15 and warning contents related to the operation of the vehicle 1 based on the warning control signal transmitted by the control unit 100 (490). .

Specifically, as shown in FIG. 10 , the display unit 350 indicates that the area where the vehicle 1 is currently located is a hay area with dry grass, an area with paper or fallen leaves, and the temperature of the engine exhaust heat recovery device 10 is If the temperature is higher than a predetermined temperature, it is an area where there is a risk of fire, so a warning message to move the vehicle 1 without parking or stopping may be displayed.

That is, since the current temperature of the engine exhaust heat recovery device 10 of the vehicle 1 is equal to or higher than a predetermined temperature, it is possible to warn that there is a risk of fire caused by an object located around the vehicle 1 .

In addition, in order to drive the engine 15 of the vehicle 1 to charge the battery 80 even though the temperature of the current engine exhaust heat recovery device 10 of the vehicle 1 is higher than a predetermined temperature, it is necessary to get out of the fire risk area. A warning message can be displayed.

According to the vehicle 1 and the vehicle 1 control method according to the embodiment described above, the temperature of the engine exhaust heat recovery device 10 of the vehicle 1 is detected, and the vehicle 1 is detected based on the detected temperature. ), it is possible to control the driving of the engine 15 for charging the battery 80 in a fire risk area by determining whether the engine 15 is driven. Through such control of the vehicle 1, occurrence of a fire around the vehicle 1 due to the high-temperature engine exhaust heat recovery device 10 can be prevented.
