Patent attributes
A mobile telecommunications device for providing an in-vehicle driver warning system during a vehicle journey using sensed driving information and local traffic information is described. The mobile telecommunications device comprises: a sensor set comprising at least one of an image sensor, an audio sensor, a geographic positioning sensor and an accelerometer; a user interface for receiving user input; a processor operatively connected to the sensor set and the user interface; a wireless communications module for communicating with a remote server, the wireless communications module being operatively connected to the processor; the processor, through its connection to the user interface, determining, during the vehicle journey, using the inputs received by the user interface, or through its connection to the sensor set, using sensor data received from the sensor set, a start of a driving period during which the mobile device is removably installed to the vehicle and the vehicle is in use; the processor, through its connection to the sensor set, using the sensor data received from the sensor set during the driving period to derive, in use, the sensed driving information associated with how the vehicle is driven; the processor, through its connection to the wireless communications module, receiving the local traffic information obtained from the wireless communications module, the local traffic information concerning other vehicles in the vicinity of the mobile telecommunications device; the processor using, in use, the local traffic information and the driving information and determining if the current relative position and speed of the vehicle exceeds a threshold profile; and wherein the processor generates, in use, a warning signal if the current relative position and speed of the vehicle exceed the threshold profile, and, through its connection to the user interface, transmits the warning signal to the user interface for warning the driver of the vehicle.
