Abstract
A device for cleaning a camera lens (6), by means of a cleaning head, comprises a fixed cleaning head and a camera that is made mobile by means of drive means (10), the head being accommodated in a structural element (2) of the vehicle. The drive means are suitable for generating a relative movement of the camera in relation to the cleaning head, between a passive image capture position in which the camera is disposed accommodated in said structural element of the vehicle facing the cleaning head, and an active position in which the camera is deployed at a distance from the structural element of the vehicle to allow image capture. The device is particularly effective when applied to the cleaning of a reversing camera implanted in motor vehicles.
Claims18
A device for cleaning a lens of a driving assistance video camera of a motor vehicle by a cleaning head, in which the video camera and the cleaning head face each other in a position for cleaning the lens and are at a distance from each other in an active imaging position, the device comprising:
- a fixed cleaning head;
- and
- a video camera that is moved by driving means,
- the head being housed in a structural element of the vehicle and the driving means being configured to generate a movement of the video camera relative to the cleaning head between a passive position in which the video camera is housed in said structural element of the vehicle facing the cleaning head and an active position in which the video camera is deployed at a distance from the structural element of the vehicle to enable imaging.
A method of cleaning a motor vehicle video camera in which said video camera is cleaned by ejection of liquid from a cleaning head, the method comprising:
- generating instructions for interchangeably moving the video camera depending on input data from a passive position in which the video camera is retracted into the structure of the vehicle and an active imaging position in which the video camera is deployed;
- and
- generating an instruction for ejection of liquid by the cleaning head when at the same time the video camera is in said passive position and the cyclic conditions for triggering cleaning are complied with.
