Abstract

PROBLEM TO BE SOLVED: To guide the passing route, along which a mobile object really moves, in the past to the destination while reproducing it without depending on any human memory by storing time sequentially found current positions as the passing route and presenting that stored passing route. SOLUTION: When the storage instruction signal of passing route is inputted to a controller 2 by operating a manipulator 6, based on a signal inputted from a GPS sensor 5, the controller 2 time sequentially operates the positions of vehicle, on which the controller itself is loaded, and stores these time sequentially found current positions in a storage device 8 for read/write as the passing route. In past passing route presentation mode, an image signal corresponding to the past passing route stored in the storage device 8 for read/write is generated and outputted to an image display 3a of head-up display 3. Thus, image indication light L corresponding to the passing route is emitted from that image display 3a and presented for a driver as image information.

In a conventional route presenting apparatus, after a destination is set in advance, a route to the destination is determined and presented. However, since the route to the destination is determined based on the map information, it is not possible to cope with ever-changing road conditions such as road construction and traffic congestion. Therefore, it may be necessary to travel on a route that deviates from the presented route. In addition, when the vehicle deviates from the presentation route, the vehicle may arrive at the destination early. In the case of re-progressing on a route that deviates from such a presentation route, the conventional device cannot cope with the problem and must rely on the memory of the driver.

[0004] It is an object of the present invention to provide a route presentation device that can solve the above-mentioned problem.
