Title: On-off control device and method of back monitor display of car navigation
Inventor: ARAI TOSHIAKI
IPC: G01C21/26
Filed: 2021-08-24
Abstract: To solve such problems that, in the conventional car navigation, a back monitor display becomes off when a shift knob of a transmission is moved to a position other than a reverse position by a turn-back operation for parking, therefore, a positional relation between the own vehicle and a parking place cannot be grasped with a back monitor in that period of time, and, when delay is put to a signal on the off side of a reverse switch, since a back monitor image continues until the delay time is terminated even if parking is completed and the knob is shifted to a position other than the reverse position, a normal car navigation operation cannot be performed in that period of time.SOLUTION: Off delay is added to a signal of a reverse switch, and the off delay is immediately released when a parking brake is pulled.SELECTED DRAWING: Figure 1
