摘要: A cart includes: a body; wheels; a drive unit, driving each of the wheels; a handle, receiving a user's operation; an input detection sensor, detecting a load and/or moment applied to the handle; a rotation number sensor, detecting number of rotations of each of the wheels; and a control device, setting a target propulsive force to be output as a propulsive force from each of the wheels based on the load and/or moment, and controlling the drive unit to output the target propulsive force as the propulsive force. If the number of rotations of the wheel located on a side close to a turning center exceeds a predetermined threshold during turning, the control device sets the target propulsive force of the wheel located on a side away from the turning center to be less than the target propulsive force set based on the load and/or moment.

摘要: A walk power mower having a cutting deck supported upon the ground by a front and rear wheel(s). The mower includes a traction drive system incorporating a bidirectional transmission adapted to propel the mower alternatively in both forward and reverse directions. In some embodiments, the mower may include a single bidirectional transmission (e.g., powering only rear wheel(s) or only front wheel(s) of the mower), while in other embodiments, two bidirectional transmissions may be provided to power both the front and the rear wheel(s). In other embodiments, the mower may include a bidirectional transmission powering the rear wheel(s), while the front wheel(s) may be attached to the deck via a caster assembly.

摘要: A power assist device may include a motor, a motor driving circuit, sensors to output signals in accordance with a rotational speed of the wheel, a memory, and a signal processor. The memory stores information of a parameter defining a transfer function that interrelates a total torque to be input to the vehicle and a rotational speed of the wheel, and an inverse transfer function thereof. Based on the inverse transfer function, the signal processor determines an estimated value of total torque from a detected value of rotational speed of the wheel. Moreover, based on the transfer function, the signal processor updates at least a portion of the information of the parameter so that, for example, an error between a detected value of rotational speed of the wheel and an estimated value of rotational speed of the wheel as determined from the estimated value of total torque is reduced.

摘要: A mobile X-ray imaging apparatus has an angle sensor and a movement calculation circuit that controls the driving of drive wheels based on the turning angle of auxiliary wheels relative to a straight moving direction of the base unit when a fine movement switch instructs movement of the base unit in the fine movement mode. The turning angle of auxiliary wheels is detected by a turning angle sensor and the rotation of the pair of drive wheels is controlled by the movement calculation circuit as the auxiliary wheels turns to the straight moving direction.

摘要: An electric push cart includes a motor; a drive wheel that is rotationally driven by the motor; a cart frame that rotatably supports the drive wheel and includes left and right handles for a user to hold; a controller that drives the motor and issues a warning. The controller issues a warning when a motor-stop condition is fulfilled as a result of an increase in load on the motor when driving the motor and stops the drive of the motor after a given time has elapsed.

摘要: A power assist system for a wagon is provided. The power assist system provides a rotational force to one or more drive wheels under certain conditions to provide propulsion for the wagon. The power assist wagon preferably includes a drive system for providing the rotational force to the drive wheel, a control system for determining when the drive system should be activated and how much propulsion assist to provide to the drive wheel, and a power system for providing power to the drive system. The power assist wagon may also have a safety cut-off system to preclude the drive system from providing a rotational force to the drive wheel 16 even when the system is in the “on” mode.

摘要: A transporter for transporting a subject over a surface that may be irregular. The transporter includes a support platform for supporting a load, the loaded support platform defining fore-aft and lateral planes and characterized by a load distribution. A plurality of ground contacting elements are coupled to the support platform. At least one of the plurality of ground contacting elements is driven by a motorized drive arrangement. A sensor module generates a signal indicative of the load distribution of the loaded support platform. Based at least on the load distribution, a controller commands the motorized drive arrangement.
