and the control module is used for matching a reminding mode of the vehicle according to the fatigue grade and controlling a reminding device of the vehicle to carry out fatigue reminding on the driver according to the reminding mode.
8. The apparatus according to claim 7, wherein before the reminding device of the vehicle is controlled to remind the driver of fatigue according to the reminding manner, the control module further comprises:
a receiving unit for receiving a modification instruction of the driver;
and the correcting unit is used for identifying a reminding intention according to the modifying instruction and correcting the fatigue grade or the reminding mode according to the reminding intention.
9. The apparatus of claim 7, wherein the control module comprises:
the first control unit is used for controlling at least one acoustic reminding device to play voice to carry out acoustic reminding when the fatigue grade is a first-grade fatigue grade;
the second control unit is used for controlling the olfactory reminding device to release stimulating smell to remind olfactory when the fatigue grade is a secondary fatigue grade;
and the generating unit is used for controlling the vehicle-mounted terminal to be connected with a preset terminal for communication and generating navigation data according to the nearest rest area and the current position of the vehicle so as to guide the vehicle to the rest area when the fatigue level is a three-level fatigue level.
10. A vehicle, characterized by comprising: the fatigue driving detecting device of the vehicle according to claims 7 to 9.
