A mobility device that can accommodate speed sensitive steering, adaptive speed control, a wide weight range of users, an abrupt change in weight, traction control, active stabilization that can affect the acceleration range of the mobility device and minimize back falls, and enhanced redundancy that can affect the reliability and safety of the mobility device.

In an electric vehicle, a power supplier includes a software type condenser charging circuit and a hardware type condenser charging circuit. The software capacitor charging circuit operates when a controller controls the software type condenser charging circuit while monitoring a voltage between opposite ends at an initial charging stage. The hardware type condenser charging circuit is operated when the controller controls the hardware type condenser charging circuit without monitoring the voltage between the opposite ends of the DC-link condenser or by direct switching manipulation of a user.

An electric walking assisting vehicle configured such that in accordance with operating amounts acting on an operation part, driving of driving motors is controlled and includes an inclination detector which detects inclination of a vehicle body in a forward-backward direction, and on flat land where inclination is less than a threshold, with an operation origin of the operation part as a center, the driving motors are controlled to generate torque in a forward direction by operation of pushing the operation part forward and to generate torque in a backward direction by operation of pulling the operation part backward, on an uphill road on which the inclination is the threshold value or more, the operation origin is shifted to an pulling operation side, and on a downhill road on which the inclination is the threshold value or more, the operation origin is shifted to a pushing operation side.

A self-propelled machine includes a drive motor, a handle having two grips, an electromechanical converting device, and a speed adjusting element configured to move relative to the handle to adjust a rotational speed of the drive motor and configured to be operated by a user when the user holds one of the two grips with a single hand. The speed adjusting element is disposed between the two grips. The electromechanical converting device is configured to convert a positional change of the speed adjusting element into an electrical signal for adjusting the rotational speed of the drive motor. The speed adjusting element is movable between a first position and a second position. The rotational speed of the drive motor when the speed adjusting element is in the first position is greater than the rotational speed of the drive motor when the speed adjusting element is in the second position.

A vehicle includes a user-actuatable switch and a controller. When the switch is actuated, the controller is adapted to effect a regenerative braking command to actuate a regenerative brake system when a vehicle speed is above a threshold speed, and to effect a parking brake command to actuate an electric park brake when the vehicle speed is less than or equal to the threshold speed.

System and method configured to determine a direction of movement of a vehicle in response to a brake being released or in response to initiating movement of the vehicle from a stopped position along a route. The direction of movement is determined based on a selected travel direction of the vehicle, a grade of the route, and at least one of applied tractive efforts or applied braking efforts.

A vehicle control system determines an upper non-zero limit on deceleration of a vehicle to prevent rollback of the vehicle down a grade being traveled up on by the vehicle. The upper non-zero limit on deceleration is determined by the controller based on a payload carried by the vehicle, a speed of the vehicle, and a grade of a route being traveled upon by the vehicle. The controller is configured to monitor the deceleration of the vehicle, and to automatically prevent the deceleration of the vehicle from exceeding the upper non-zero limit by controlling one or more of a brake or a motor of the vehicle. The controller also is configured to one or more of actuate the brake or supply current to the motor of the vehicle to prevent rollback of the vehicle while the vehicle is moving up the grade at a non-zero speed.

In a vehicle capable of external charging, when the connection of an inlet of the vehicle with a charging cable is detected, an ECU transmits a locking command to a locking device. When it is determined that the locking device is in a locked state, the ECU permits external charging, and when it is determined that the locking device is not in the locked state, the ECU does not permit external charging. When the ECU does not permit external charging, the ECU displays information about manual locking by manual operation. When it is determined that the locking device is in the locked state after the ECU does not permit external charging, the ECU permits external charging.
