Abstract
A fuel efficiency degradation amount displaying device detects a tire air pressure and calculates an amount of degradation of fuel efficiency of the vehicle compared to fuel efficiency in a case that the tire air pressure is appropriate. Then the fuel efficiency degradation amount displaying device indicates not only a warning of the decrease of the tire air pressure but also the amount of the fuel efficiency degradation. Therefore the driver can recognize the amount of the degradation clearly and intuitively. As a result, it is possible to prevent drivability of the vehicle from getting worse, because the driver can adjust, knowing a relation between the tire air pressure and the fuel efficiency, the tire air pressure to the appropriate tire air pressure.
