Abstract

The present invention has an object of providing a vehicle-running-state display method capable of easily displaying a running state of a vehicle. The invention provides a vehicle-running-state display method, including the steps of obtaining position information, time information, speed information, and acceleration information of a vehicle, detecting a special state of the vehicle, based on the position information, the time information, the speed information, or the acceleration information, displaying a track of the vehicle on a map screen, based on the position information and the time information, and displaying the detected special state of the vehicle, on the map screen on which the track is displayed.

Claims

1. A vehicle-running-state display method, comprising the steps of:

obtaining a speed excess state in which the speed of the vehicle exceeds a set speed during at least a predetermined time, a rapid acceleration state in which the speed of the vehicle increases by at least a predetermined speed during a predetermined time, and a rapid deceleration state in which the speed of the vehicle decreases by at least a predetermined speed during a predetermined time, based on position information, time information, or speed information of the vehicle, by a processor;

displaying a track of the vehicle into a map screen of a display, based on the position information and the time information, by the processor; and

displaying the detected speed excess state, rapid acceleration state, or rapid deceleration state, on the map screen on which the track is displayed, by the processor.

2. The vehicle-running-state display method according to claim 1, further comprising the step of changing a set condition of obtaining the speed excess state, the rapid acceleration state, or the rapid deceleration state.

3. A vehicle-running-state display method comprising the steps of:

storing operating information and an image at every first predetermined time, and recording the operating information and the image stored for a predetermined period into a nonvolatile recording unit when a recording condition is established, by the processor;

recording position information and time information of the vehicle at every second predetermined period longer than the first predetermined time, into the nonvolatile recording unit, by the processor;

obtaining a speed excess state in which the speed of the vehicle exceeds a set speed during at least a predetermined time, a rapid acceleration state in which the speed of the vehicle increases by at least a predetermined speed during a predetermined time, a rapid deceleration state in which the speed of the vehicle decreases by at least a predetermined speed during a predetermined time, an idling state in which there is no movement of the vehicle during at least a predetermined time, and a long-time driving state in which the movement of the vehicle continues during at least a predetermined time, based on the operating information, by the processor;

displaying a track of the vehicle on the map screen of a display, based on the position information and the time information at each second predetermined period, by the processor; and

displaying the speed excess state, the rapid acceleration state, the rapid deceleration state, the idling state, or the long-time driving state on the map screen on which the track is displayed, by the processor.

4. The vehicle-running-state display method according to claim 3, further comprising the step of changing a setting condition of obtaining the speed excess state, the rapid acceleration state, the rapid deceleration state, the idling state, or the long-time driving state.
