Patent ID: 7853391

Claim:
An energy-saving driving promotion system comprising: a vehicle state detecting device configured to detect a vehicle state; a current value calculating device configured to calculate a current value associated with an accelerator operation amount or a vehicle drive power, based on the detected vehicle state; a recommended value calculating device configured to calculate a recommended value associated with the accelerator operation amount or the vehicle drive power, based on the detected vehicle state; an indicator device configured to indicate a relationship between the calculated recommended value and the calculated current value; and an acceleration intention determining device configured to determine whether a driver intends to accelerate, based on the detected vehicle state, wherein if the acceleration intention determining device determines that the driver intends to accelerate, the recommended value calculating device calculates a larger recommended value when the acceleration intention determining device determines that the driver intends to accelerate than when the acceleration intention determining device determines that the driver does not intend to accelerate, the energy-saving driving promotion system, further comprising: an index value calculating device configured to calculate an index value indicating a driver's intention to accelerate based on the detected vehicle state, wherein the acceleration intention determining device determines that the driver intends to accelerate if the index value calculated by the index value calculating device exceeds a predetermined first threshold, wherein the indicator device is a lamp of which an on-off state changes when the calculated current value exceeds the calculated recommended value, wherein there is further provided a provisional determination device configured to provisionally determine that the driver intends to accelerate if the index value calculated by the index value calculating device exceeds a second threshold that is smaller than the first threshold, and wherein if the provisional determination device provisionally determines that the driver intends to accelerate, the on-off state of the lamp remains in a current state for a predetermined period of time.
