Device for instructing the driver on driving operation to improve fuel efficiency

摘要

Coaching for driving operation for improving the fuel efficiency is provided. A first region and a second region adjacent to the first region are visually distinguishably displayed in one direction with respect to a predetermined reference position. A third region and a fourth region adjacent to the third region are visually distinguishably displayed in another direction with respect to the reference position. The first region is established as a region indicating a fuel-efficient driving operation state for an operation for driving the vehicle. The second region is established as a region indicating a fuel-inefficient driving operation state for the operation for driving the vehicle. The third region is established as a region indicating a fuel-efficient driving operation state for an operation for braking the vehicle. The fourth region is established as a region indicating a fuel-inefficient driving operation state for the operation for braking the vehicle. Extensible graphics is provided at the reference position. For each operation for driving and braking the vehicle, the length of the graphics is changed based on an operating state of the vehicle according to the operation, thereby allowing a driver to recognize whether his/her operation is fuel-efficient.
