Abstract:
A wheelchair is disclosed that includes a seat, a pair of wheels, a detection part indicating the presence or absence of a user on the seat, electric brake units switching between applying braking forces to and releasing braking forces from the wheels based on control signals, and a control part connected to the detection part and the electric brake units and outputting the control signals to the electric brake units. The control signals include a first control signal causing the braking forces by the electric brake units to be applied to the wheels and a second control signal causing the braking forces by the electric brake units to be released therefrom. The first control signal is output when the detection part indicates the absence of the user on the seat, and the second control signal is output when the detection part indicates the presence of the user on the seat.
