Abstract: The present disclosure provides a vehicle operation control method, device and system.

Abstract: The present disclosure discloses a driver fatigue alert method for a vehicle. The method includes: if a driver fatigue detection device detects driver fatigue information of the present vehicle, then sending the driver fatigue information of the present vehicle to an alert device and a wireless communication device; sending, by the wireless communication device, the driver fatigue information to the outside; and generating, by the alert device, an alert signal according to the driver fatigue information. The present disclosure further discloses a driver fatigue alert system for a vehicle, where the system includes: a driver fatigue detection device; a wireless communication device communicatively connected with the driver fatigue detection device, configured to send driver fatigue information to the outside wirelessly; and an alert device communicatively connected with the driver fatigue detection device and the wireless communication device.

Abstract: The invention discloses a failure alert method for a vehicle, the method including: if a failure detection device of the present vehicle detects failure information of the present vehicle, then sending the failure information of the present vehicle to an alert device and a wireless communication device; sending, by the wireless communication device, the failure information to the outside; and generating, by the alert device, an alert signal according to the received failure information. The invention further disclose a failure alert device for a vehicle, the device including: a failure detection device; a wireless communication device communicatively connected with the failure detection device, configured to send failure information wirelessly to the outside; and an alert device communicatively connected with the failure detection device and the wireless communication device. The invention alleviates in effect a traffic accident from occurring due to the failure of the vehicle.

Abstract: A navigating device and a vehicle are disclosed. A V2X communication circuit electrically connected with the navigating unit may be additionally provided in the navigating device; thereby a communication connection with nearby vehicles may be established via V2X communication. Since V2X is a kind of short-range communication, it is possible to perform interactions with nearby vehicle by establishing communication connection with nearby vehicles via V2X communication, and may address the technical problems that the navigating device in the related art have unitary functions and thus cannot perform interaction with nearby vehicles.
