FUEL-EFFICIENT DRIVING DIAGNOSIS DEVICE, FUEL-EFFICIENT DRIVING DIAGNOSIS SYSTEM, AND FUEL-EFFICIENT DRIVING DIAGNOSIS METHOD

摘要

PPROBLEM TO BE SOLVED: To improve motivation of a driver to improve shift lever position selection operation and improve fuel-efficient driving knowledge and awareness of the driver. PSOLUTION: A shift lever position judgment unit 11b1 determines whether the shift lever position of a vehicle 1a meets a specified condition. When a traveling distance summing unit 11c determines that the shift lever position meets a specified condition, it sums the optimum shift lever position driving distance. If the traveling distance summing unit 11c determines that the shift lever position does not meet the specified condition, it sums a less-than-optimum shift lever traveling distance. A fuel-efficient driving rating unit 12 rates operation by the driver, based on respective summed values summed by the traveling distance summing unit 11c. A fuel-efficient driving advice generator 13 announces fuel-efficient driving advice to the driver according to the rating results, together with the rating results. Therefore, the driver is prompted to select the best shift lever position for good fuel consumption, and the fuel-efficient driving knowledge and awareness of the driver can be improved.
