Abstract:
1. A travel energy learning device for a host vehicle having a transmission shaft, a motor for driving the transmission shaft to transmit a driving force from the motor to a wheel and a rechargeable battery for powering the motor, a revolution sensor which detects rotary speed of the transmission shaft and a torque sensor which detects torque output by the transmission shaft, the energy learning device comprising: a road section identifying unit that identifies a road section on which the host vehicle is currently located; a travel condition information obtaining unit that obtains travel condition information that indicates a travel condition when the host vehicle has traveled the road section; a work rate deriving unit that derives information that indicates a work rate of the transmission shaft based on a signal from the revolution sensor and on a signal from the torque sensor; and an energy information accumulating unit that:
