Abstract
A movable structure driving unit is a movable structure driving unit used for a movable structure, including: an electric motor that is electrically connected to a power supply and that drives a front wheel; a rear-side motive power source that drives a rear wheel; a jump detector that detects a jump of the front wheel from ground; and a motor controller that controls driving of the electric motor. The motor controller stops supply of a driving current from the power supply to the electric motor when the jump of the front wheel from the ground is detected in a state in which driving of the front wheel and the rear wheel is instructed.

A movable structure driving unit used for a movable structure having a front wheel and a rear wheel, comprising:
- an electric motor that is electrically connected to a power supply and that drives the front wheel;
- a rear-side motive power source that drives the rear wheel;
- a jump detector that detects a jump of the front wheel from ground;
- and
- a motor controller that controls driving of the electric motor, wherein
- during all of the front wheel and the rear wheel are instructed to be simultaneously driven, the motor controller stops supply of a driving current from the power supply to the electric motor when the jump of the front wheel from the ground is detected.
A movable structure driving unit used for a movable structure having a front wheel and a rear wheel, comprising:
- an electric motor that is electrically connected to a power supply and that drives the front wheel;
- a rear-side motive power source that drives the rear wheel;
- a detector that detects a change of a weight of a part of the movable structure, acting on a suspension device from above;
- and
- a motor controller that controls driving of the electric motor, wherein
- during all of the front wheel and the rear wheel are instructed to be simultaneously driven, the motor controller stops supply of a driving current from the power supply to the electric motor when an amount of reduction of the weight detected by the detector is greater than or equal to a predetermined value.
