Patent Images

1. A drive assisting apparatus for displaying an image around a vehicle, which is acquired by an on-vehicle camera, on a screen of an on-vehicle monitor, comprising:

  • a data table for storing thereinto locus data which contains locus display data and adjusting data, said locus display data being used to display a travel predicted locus of the vehicle corresponding to a steering angle of a steering wheel on the screen, and said adjusting data being used to adjust a display position of the travel predicted locus on the screen based upon said locus display data;

    steering angle detecting means for detecting the steering angle of the steering wheel; and

    drive assisting image producing means for reading out said locus data corresponding to the steering angle detected by said steering angle detecting means from said data table during a normal driving operation subsequent to a setting operation, for producing a drive assisting image by superimposing the travel predicted locus on the image around the vehicle based upon the locus display data and the adjusting data, which are contained in said read locus data, and for outputting said drive assisting image to said on-vehicle monitor,wherein said drive assisting apparatus includes display position adjusting amount setting means for setting a value of the adjusting data contained in the locus data corresponding to said steering angle, andwherein based upon a value of adjusting data of said locus data with respect to a typical steering angle, said display position adjusting amount setting means calculates, during said setting operation, values of adjusting data of said locus data with respect to all of other steering angles.
