Device and method for detecting and displaying the rear and/or side view of a motor vehicle

摘要

A device for detecting and displaying the rear and/or side traffic of a motor vehicle is to be improved upon such that the driver can safely and quickly detect the present traffic situation by way of the overall image shown, in particular when the direction of travel is changed. This is accomplished in that the device for detecting and displaying the rear and/or side view of a motor vehicle (1) comprises a first apparatus (3) for producing images of the optically detected rear view (A), one or more further apparatuses (2) for producing images of the optical side view (B,C) of the motor vehicle (1), a display apparatus (6) adapted to display images or image sections of the first and/or the further apparatuses (2, 3) in partial areas (T1, T2), and a control apparatus (5) adapted to select the images or image sections and to assign them to the partial areas (T1, T2). The images or image sections are selected according to the signals of a driving direction indicator (7) and/or the signals of a sensor (8) that represents the steering direction and are assigned to the partial areas (T1, T2). Also provided is a method for detecting and displaying an overall image from an image section or overlapping image sections.

主权项

1. A device for sensing and displaying the surroundings at the rear and sides of a motor vehicle, said device comprising:
a first apparatus for generating images of the optically sensed surroundings rearward of the motor vehicle, wherein said first apparatus comprises a first camera disposed at a rear portion of the motor vehicle, and wherein said firs camera is generally centrally located at the rear portion of the motor vehicle; second and third apparatuses for generating images of the optical surroundings at first and second sides of the motor vehicle, respectively, wherein said second apparatus comprises a second camera disposed at an exterior rearview mirror assembly at the first side of the motor vehicle and wherein said third apparatus comprises a third camera disposed at an exterior rearview mirror assembly at the second side of the motor vehicle; a display apparatus operable to display images generated by the first apparatus and the second and third apparatuses at respective center, first side and second side partial regions of a display screen of the display apparatus; a control apparatus operable to select and assign the images to the respective center partial region, first side partial region and second side partial region; wherein, during forward travel of the motor vehicle, the control apparatus is operable to vary the horizontal extents of the partial regions and respective displayed images responsive to signals of a sensor that represent the steering angle of the motor vehicle; wherein, during forward travel of the motor vehicle, the images are selected and the images are assigned to and displayed at the respective partial regions of the display screen as a function of (i) a signal of a travel direction indicator and (ii) a signal of a sensor which represents the steering angle of the motor vehicle; wherein, during forward travel of the motor vehicle, the horizontal extents of the partial regions are dynamically adjusted according to the steering angle in order to display a dynamic composite seamless image which is composed of image sections with dynamically adaptive horizontal extents; wherein, during forward travel of the motor vehicle, at least the first side partial region and second side partial region are varied in their horizontal extents responsive to a change in the steering angle, and wherein the degree of variation of their horizontal extents is a function of a degree of chance in the steering angle of the motor vehicle; wherein the displayed images at adjacent partial regions are merged together in such a way that the displayed dynamic composite seamless image has seamless transitions in the boundary regions; and wherein, during forward travel of the motor vehicle, and as the steering angle to the first side of the motor vehicle increases, the horizontal extent of the image displayed at the first side partial region increases and the horizontal extent of the image displayed at the second side partial region decreases, and wherein the degree of variation of the horizontal extent of the images displayed at the first side partial region increases as a function of a degree of change in the steering angle of the motor vehicle and wherein the degree of variation of the horizontal extent of the images displayed at the second side partial region decreases as a function of a degree of change in the steering angle of the motor vehicle.
