摘要： A walking aid vehicle (1) includes: an operation part (3) provided on an upper portion of a vehicle body for grasping by a user in a walking posture; a detector (30) for detecting an operation force applied to the operation part; and an inclination detector (20) for detecting inclination of the vehicle body. When an advance direction inclination detected by the detector is less than threshold, a normal control (100) generates a normal direction torque in the drive motor (40L, 40R) responsive to pushing the operation part (3) forward and generates a reverse direction torque in the drive motor responsive to pulling the operation part rearward, and when the advance direction inclination is equal to or greater than threshold and pushing operation force is detected, a shift to a pull control (110) is made which generates normal direction torque in the drive motor responsive to a pulling operation force.

摘要： A mobile object is configured so as to be capable of moving front and rear bases 10,30 object to each other in order to make a wheel base provided between the front wheels 12 and the rear wheels 32 expandable and contractible. The front base 10 moves so as to be expand and contract the tread width between the front wheels 12 in association with the expansion and the contraction of the wheel base achieved. The seating part 41 is configured so as to turn forward in association with the relative movement of the front and rear bases 10,30 in order to contract the wheel base and the tread width. The seating part 41 is configured so as to turn backward in association with the relative movement of the front and rear bases 10,30 in order to expand the wheel base and the tread width.

摘要： An electric vehicle includes: a mobile base capable of traveling by an electromotive drive; a seat including a seating portion having a sitting surface; and a battery capable of supplying electric power used in the electromotive drive. The seating portion of the seat includes a receiving portion capable of receiving the battery and arranged on a seat lower side with respect to the sitting surface. The mobile base is changeable between an expanded state in which a wheelbase is expanded and a contracted state in which the wheelbase is more contracted than in the expanded state. The seat is movable between a sitting position that the sitting surface faces a vehicle upper side in an expanded state of the mobile base, and a retracted position that the seating portion is retracted from the sitting position to a vehicle front side in a contracted state of the mobile base.

摘要： An operating device of an electric vehicle enables an electric vehicle to be operated, the electric vehicle having: left and right driving wheels; and left and right driving motors respectively independently driving these left and right driving wheels. The operating device has: a joystick operable to move so as to issue a turning direction instruction of the vehicle; and a traveling instruction portion issuing a traveling instruction of the vehicle by operation different from movement operation of this joystick. The joystick has a grip operable to be gripped by an occupant of the vehicle. By making a difference between rotating speeds of the left and right driving motors based on a combination of the turning direction instruction of the joystick and the traveling instruction of the traveling instruction portion, a gentle turn or a pivotal brake turn of the vehicle is performed.
