Patent ID: 8655523

Claim:
A vehicle control device comprising: a drive element having a rotating electric device and a power supply device which is connected to the rotating electric device and which includes a step-up converter that enables boosting a voltage of a battery device side and supplying the boosted voltage to a rotating electric device side; an obtaining element to obtain a fuel-efficient running command from a user; a memory device that stores a normal operation condition map of the rotating electric device for allowing the step-up converter in the power supply device to operate normally within a voltage range between the voltage of the battery device side and a normal upper limit voltage of the step-up converter and a restricted operation condition map of the rotating electric device for allowing the step-up converter to operate in a restricted manner within a voltage range between the voltage of the battery device side and a restriction upper limit voltage which is set below the normal upper limit voltage; and a control element that controls the drive element, wherein the control element includes: a fuel-efficient running command determination part to determine whether the fuel-efficient running command has been obtained; and a switching part to switch an operation condition of the rotating electric device between operation according to the restricted operation condition map when the fuel-efficient running command has been obtained and the operation according to the normal operation condition map when the fuel-efficient running command has not been obtained.
