PURPOSE: To make effective use of energy and obtain a desirable travel feeling in a vehicle with an electric motor by executing an energy-saving mode on the basis of the operation start of a brake, whereas releasing the energy-saving mode when the vehicle speed and human power are respectively the fixed value or more.
CONSTITUTION: In a vehicle with an electric motor, a human power driving system and an electric power driving system are disposed in parallel, that is, a driving shaft 30 is driven by human power 32 for driving a crankshaft and the electric power of a motor 22 so as to rotate a rear wheel 14, and electric power is controlled by a controller 54 according to the change of human power. In this case, a human power (depressing power) detecting means 46, a vehicle speed detecting means 56 and a brake switch 84 are respectively connected to the controller 54, and the controller 54 executes a braking energy-saving mode on the basis of the operation start of a brake, whereas releases the energy-saving mode when the detected vehicle speed and human power are respectively the fixed value or more. This results in securing the effective use of energy and a desirable travel feeling.
