Abstract: This application provides an electronic device, to reduce a probability that a screen stalling phenomenon. A timing control unit sends one first pulse of a tearing effect signal every a first preset time T1. The timing control unit sends S second pulses of the tearing effect signal when a transceiver unit does not receive an Nth frame of display data within a preset time. The processing unit receives the Nth frame of display data in the (N+1)th frame, and controls, based on the Nth frame of display data, the display to display an Nth frame of image.

Abstract: The disclosure discloses a Bluetooth-based system for automatically matching a vehicle-mounted device with a mobile phone terminal. The system controls a vehicle-mounted device and a mobile phone terminal to turn on/off their respective Bluetooth function based on a vehicle ignition switch signal. In such a way, the driver needn't to turn on, match, and turn off the Bluetooth functions of the vehicle-mounted device and the mobile phone terminal manually. More intelligentized, convenient and efficient service is provided for the drivers and the power of the mobile phone terminal can be saved.

Abstract: A method for quickly calculating mileage includes the steps: A, receiving report data from a vehicular terminal and updating data center according to the report data; B, receiving an inquiry request which includes a vehicle number, a first time point which is earlier than a second time point and the second time point which are requested to inquire; C, inquiring the data center to acquire a first total mileage value to which the time point that is proximate to the first time point corresponds and a second total mileage value to which the time point that is proximate to the second time point corresponds; D, obtaining a running mileage L from the first time point to the second time point by subtracting the first total mileage value from the second total mileage value. A system for quickly calculating mileage quickly is also proposed.

Abstract: A method and a system for dispatching vehicle are provided. The method for dispatching vehicle includes the following steps: A. obtaining the vehicle information, which includes vehicle numbers, vehicle states and relative positions; B. placing the vehicle icons corresponding to the vehicle numbers in the corresponding positions on the virtual line schedule map according to the vehicle states and the relative positions; C. displaying the virtual line schedule map refreshed via step B. The system for dispatching vehicle includes vehicle information obtaining unit, vehicle states judging and processing unit, displaying unit and dispatching unit. The system realize the visual vehicle dispatching method by utilizing the virtual line schedule map, so as to implement vehicle monitoring and dispatching.
