  • Publication number: 20230421880
    Abstract: A camera monitoring system (CMS) disposed on a panel of a vehicle body. A housing is disposed on a vehicle body. A movable housing is movable along the housing. A CMS camera is disposed on one end of the movable housing. A motor part provides driving force by which the movable housing moves along the housing. A transparent part is disposed on the housing and is located in an area facing the CMS camera when the movable housing is retracted into the housing. A controller controls a driving amount of the motor part and controls turning on/off of the CMS camera.

  • Publication number: 20070005213
    Abstract: Disclosed herein is a backward control system for an automobile using telematics. The system includes: a sensor unit to sense a backward speed, presence of a backward object, and the operating state of the brake pedal and the accelerator pedal of an automobile when backward-travelling; a telematics system unit to output a control signal, when a distance between the automobile and the object is within a pre-set range in response to the signal from the sensor unit, such that the backward-travelling is automatically interrupted to thereby prevent collision with the object; and a accelerator pedal control unit and a brake pedal control unit to automatically control the operation of the accelerator pedal and the brake pedal to thereby interrupt the backward-travelling in response to the control signal outputted from the telematics system unit.
