Abstract

PROBLEM TO BE SOLVED: To facilitate the recognition of information during running and achieve safety driving by providing an information-transmitting apparatus which transmits running information between a vehicle running information external presenting apparatus recording and operating outside a vehicle and a vehicle running information internal presenting apparatus recording and operating inside the vehicle. SOLUTION: A user carries an information-transmitting device 101 and retrieves road information, sightseeing spot information, etc., with the use of a vehicle running information external presenting device 102 set outside a vehicle such as a home or shop. At this time, the information-transmitting device 101 is set on the vehicle running information external presenting device 102, thereby obtaining information of a retrieval result and information related to a deformation process. The information-transmitting device 101 is formed of a magnetic recording medium or semiconductor memory element, transmitting running information between the vehicle running information external presenting device 102 and a vehicle running information internal presenting device 103. Since the running information is recorded and operated partly outside the vehicle, an operation volume of the presenting device 103 is reduced, and operability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle traveling information presentation device for presenting traveling information to a user of a vehicle such as an automobile. This device is suitably used particularly as a navigation system using digitized map data.

[0002]

2. Description of the Related Art In recent years, a global positioning system (GPS) using artificial satellites and a vehicle navigation system using an electronic map have been widely used. However, the size of the device must be sufficiently small so that it can be installed in a limited space inside the vehicle such as a dashboard.Therefore, the number of input switches, the size of the screen, and the capacity of the computing device are limited by design. However, there is a problem that the operability when searching for roads and sightseeing spots and the listability when guiding are poor.

[0003] In order to solve this problem, a list of methods for operability by voice recognition using voice recognition and a method of superposing a touch panel on a display device to present buttons necessary for operation when necessary are listed. Regarding gender, a method of deforming a map displayed on a display device by calculation has been proposed.

[0004]

In the above-mentioned method, it is difficult to say that the operability and the listability have been improved as a whole.
First, in the method using speech recognition, the problem of malfunction when recognition is erroneous cannot be avoided. In the method using the touch panel, the display area is degraded because the display area is occupied by the buttons. In the method of deforming the map, the amount of calculation is significantly increased as compared with the case where the map is not deformed, and the operability is reduced due to the longer rendering time. Therefore,
It is an object of the present invention to provide a vehicle traveling information presentation device that is excellent in both browsability and operability.

[0005]

In order to achieve the object, a vehicle running information presenting apparatus according to the present invention is provided as a means for recording and calculating running information relating to a vehicle. It divides into a traveling information presentation device and an in-vehicle traveling information presentation device that performs recording and calculation inside the vehicle, and transmits traveling information between the out-of-vehicle traveling information presentation device and the in-vehicle traveling information presentation device. An information transmission device is provided.

According to the present invention, part of the recording and calculation of the traveling information is performed outside the vehicle, so that the amount of computation of the in-vehicle traveling information presentation device can be reduced, and the operability is improved.
In addition, since the information presented in the vehicle can be suppressed to a necessary minimum, the listability of the in-vehicle traveling information presentation device is improved. The travel information is typically geographic information, but is not limited thereto, and may be travel distance, fuel consumption, and the like.

When the traveling information is geographical information, the vehicle traveling information presenting apparatus of the present invention can be used as a navigation system for planning an outing. in this case,
A system with high processing capability and high operability, such as a personal computer installed at home, is used as an outside-vehicle running information presentation device, which searches for road and sightseeing spot information and performs map deformation processing outside the vehicle. By transferring the search results and parameters related to deformation to the in-vehicle navigation device, which is a device for presenting in-vehicle travel information, the operation itself of the user conventionally performed inside the vehicle is reduced and the operability is improved. In addition, the amount of calculation required for deformation is reduced, and the operability and listability of the on-vehicle navigation device are simultaneously improved.

When the traveling information is the traveling distance and the fuel consumption, it can be used as a fuel efficiency calculation system. In this case, the system for recording the output of the travel distance detector and the remaining fuel detector is a vehicle travel information presentation device,
The operability and listability of the in-vehicle device are improved by calculating the data using a personal computer, which is an information device outside the vehicle, and displaying the fuel efficiency.
