Abstract

To make it possible to achieve a run under a desired condition within a predetermined allowable range, a vehicle speed pattern display device displaying upper and lower limit speed patterns and set for a predetermined prescribed speed pattern on a graph having one axis representing a vehicle speed and the other axis representing time or a running distance is adapted to display a target speed pattern different from the prescribed speed pattern on the graph.

Claims

1. A vehicle speed pattern display device adapted to display an upper limit speed pattern and a lower limit speed pattern, the upper and lower limit speed patterns being set for a predetermined prescribed speed pattern, on a graph having one axis representing a vehicle speed and the other axis representing time or a running distance,

the vehicle speed pattern display device displaying a target speed pattern different from the prescribed speed pattern on the graph.

2. The vehicle speed pattern display device according to claim 1, wherein

the target speed pattern displayed on the graph is a speed pattern corresponding to a driving mode targeted by a user.

3. The vehicle speed pattern display device according to claim 2, wherein

the target speed pattern selected in accordance with the driving mode is set such that at least one of an amount of exhaust gas, an amount of carbon dioxide contained in the exhaust gas, drivability, effectiveness of a running test result, and a running index obtained by combining them meets a desired condition.

4. The vehicle speed pattern display device according to claims 1, wherein

the target speed pattern is an actual vehicle speed pattern of a vehicle, the actual vehicle speed pattern being acquired from a running test of the vehicle, or a pattern obtained by correcting the actual vehicle speed pattern.

5. The vehicle speed pattern display device according to claims 1, wherein

the target speed pattern is one calculated from the prescribed speed pattern.

6. A running test method comprising driving a vehicle to test within a range between an upper limit speed pattern and a lower limit speed pattern, the upper and lower limit speed patterns being set for a predetermined prescribed speed pattern,

the running test method comprising setting a target speed pattern different from the prescribed speed pattern.

7. An auto-driving device adapted to drive a vehicle within a range between an upper limit speed pattern and a lower limit speed pattern, the upper and lower limit speed patterns being set for a predetermined prescribed speed pattern,

the auto-driving device driving the vehicle in accordance with a target speed pattern different from the prescribed speed pattern.
