Driver assistance system

摘要

The present invention relates to a driver assistance system for aiding driver vision in a vehicle, and a control transmission method of such a system. The system includes at least one camera which is arranged to be removably mounted in a docking station in the vehicle. The camera comprises a first communication means arranged to communicate with a second communication means located in the vehicle when the camera is out of the docking station. The docking station and the second communication means are connected to a central microprocessor which is further connected to a digital display which is located in the interior of the vehicle in a position where it is visible to a driver and further includes user input means. The first and the second communication means are provided with a UHF communication unit and a microwave communication unit arranged to transmit in real time the video signal from the camera to the digital display by way of microwave communication channel and to communicate remotely with the camera so as to provide remote control of camera functions by way of UHF link. The camera and the docking station further include an infra red communication means enabling to exchange data between the microprocessor and the camera when it is in the docking station so that the microprocessor is able to remote control the camera. In order to avoid battery drain and the interference respectively, the camera transmits the video signal at any particular time and a determined microwave channel and a control command are retransmitted to the required camera at regular intervals.
