Abstract:
A running control device for an electric vehicle includes: a first calculation unit that calculates a predetermined reference torque required for braking/driving the motor that provides a beneficial effect with regard to power consumption of the electric vehicle; a second calculation unit that calculates interval allocation between a first interval in which the electric vehicle is propelled by braking/driving the motor at the predetermined reference torque and a second interval in which the electric vehicle is coasted without the motor being braked or driven; a third calculation unit that calculates a control requested torque for braking/driving the motor intermittently, so as alternatingly to repeat running of the electric vehicle in the first intervals and coasting of the electric vehicle in the second intervals; and a running control unit that performs running control of the electric vehicle by braking/driving the motor intermittently according to the control requested torque.
