Description

  The present invention relates to a system for managing a driver's fuel consciousness by eco-driving, which is an energy-efficient driving operation in an automobile, and this system also reduces environmental burden by reducing CO2 emissions. It is about planning.

  In recent years, eco-driving has been recommended for automobiles, and a system for controlling a driving state of a vehicle such as fuel consumption for the eco-driving has been proposed (see Patent Documents 1 and 2). Keeping the above-mentioned eco-driving consciousness is very important for reducing the environmental load, such as reducing CO2 emissions. As driving to improve fuel efficiency, eco-driving is recommended to prevent fuel deterioration and improve fuel efficiency, such as sudden start, avoidance of sudden acceleration, constant speed driving, use of high speed stages, and idling stop. In order to improve the fuel efficiency improvement awareness of the driver, a display device has been proposed that displays fuel consumption information on the display device (see Patent Documents 3 and 4). The fuel consumption is the travel distance per unit fuel consumption.

  However, simply displaying the state of eco-driving on the display can be effective in maintaining awareness of fuel efficiency improvement, but in practice it is not always easy to implement eco-driving. The reason is, for example, an accelerator operation as one of the driving operations that leads to an improvement in fuel consumption. Although the accelerator operation is an important operation for improving the fuel efficiency of the automobile, it is difficult to determine in which mode the operation should be performed. In addition, brake operation, steering wheel operation, shift operation, etc. are also related to fuel efficiency improvement, but it is difficult to improve fuel efficiency by using these driving operations properly.

  In the present invention, while maintaining an awareness of fuel economy improvement by eco-driving, specifically, it is possible to easily implement fuel economy improvement by eco-driving, thereby realizing reduction of environmental load as a problem to be solved. .

  The present invention relates to a fuel consumption awareness management system by eco-driving, which includes a driving record card that electronically records a driver's driving operation into a plurality of driving operation items, and the driving operation for each item. Driving recording means for electronically recording on the driving record card, driving analysis means for analyzing whether or not the driving operation of each item electronically recorded on the driving recording card contributed to fuel efficiency improvement, and Display means for displaying a fuel consumption improvement state in the driving operation on the display screen, and learning of the driving operation related to the fuel consumption improvement can be performed from the display on the display screen.

  In the present invention, during driving, the driving recording means is used to electronically record the driving state of the driver on the driving record card, and after the recording is finished, the driving operation contributing to fuel efficiency improvement is analyzed for each item by the driving analysis means. Since the driving operation judged to have been improved is displayed on the display screen, each driver can learn driving operation that can improve fuel consumption from his / her own driving record displayed on the display screen It will be possible to perform further eco-driving while maintaining awareness of fuel economy improvement.

  According to the present invention, the driver records the driving operation on the driving record card by the driving recording unit, the driving operation that can automatically contribute to the improvement of the fuel consumption is analyzed by the driving analyzing unit, and the result is displayed by the display unit. Therefore, it becomes possible to learn driving operations that can contribute to fuel efficiency improvement.

FIGS. 5A and 5B show examples of electronic recording display of the driving operation on the display screen of the car navigation display 3. There are various conditions for improving fuel consumption. In rainy weather and snowy roads, the fuel efficiency deteriorates unlike normal sunny weather driving. In addition, fuel efficiency is different even on highways, mountain roads, and climbing roads. Furthermore, it is different in urban areas and congested roads. In driving operation, there is a great difference between accelerator operation, brake operation, steering wheel operation, and shift operation. In the present embodiment, as a representative example of the many fuel consumption improvement items, it is assumed that the vehicle is traveling on a normal road, and the accelerator operation, the brake operation, the steering wheel operation, and the shift operation are performed as driving operations of the fuel consumption improvement items. And The fuel consumption analysis requires travel time, travel distance, average accelerator opening, stop time, and the like. In the present embodiment, for simplification of description, travel time and travel distance are used for these fuel consumption analyses. In FIGS. 5A and 5B, the items of driving operation and fuel consumption improvement are displayed together with the driver name, travel time, and travel distance.

  The driving operation is an accelerator operation, a brake operation, a steering wheel operation, and a shift operation. On the driving operation recording screen of the car navigation display 3 shown in FIG. 5A, all the driving operations that improve fuel efficiency are performed. From the driving operation recording screen shown in FIG. 5 (b), it can be seen that the fuel efficiency has deteriorated due to the accelerator operation and the fuel efficiency has not been improved as a whole.
