Abstract: A control device sets a second electricity control switch in an intermediate state in a process of switching a discharge battery for supplying a drive unit with an electrical current from a first battery to a second battery. Subsequently, when a comparative relationship between an electric potential of a smoothing capacitor and an electric potential of the second battery fulfills an intermediate state termination condition, the control device sets the second electricity control switch in a bidirectional conduction state. The intermediate state is when an electrical current flowing from the second battery to the drive unit is allowed, and an electrical current flowing from the drive unit to the second battery is inhibited. The bidirectional conduction state is when both of the electrical current flowing from the second battery to the drive unit and the electrical current flowing from the drive unit to the second battery are allowed.

Abstract: An electrically assisted bicycle includes a crank shaft, pedals, an electric motor, a pedal effort sensor that detects a pedal effort exerted on the pedals, a propelling detection sensor that detects that the electrically assisted bicycle is starting to be propelled, and a controller that executes a first control in which a command value provided to the electric motor is obtained based on the output of the pedal effort sensor and a second control in which a command value provided to the electric motor is obtained based on the output of the pedal effort sensor and the output of the propelling detection sensor. The controller is configured or programmed to select the first control or the second control as a calculation method of a command value provided to the electric motor during a period of time from a state in which the electrically assisted bicycle is stopped until a detection of the rotation of the crank shaft.

Abstract: An electrically assisted bicycle includes a motor controller that calculates a command value which determines a magnitude of an assisting torque based on at least an output of a pedal torque detector. The motor controller switches between a first control and a second control, in which a time required for the assisting torque to change to meet a change in the pedal torque is shorter and the amount of change in the assisting torque to meet a change in the pedal torque is greater than in the first control.
