Title:
TRAVELING CONTROL METHOD AND TRAVELING CONTROL DEVICE FOR AERIAL WORK PLATFORM
Document Type and Number:
WIPO Patent Application WO/2019/130421
Kind Code:
A1
Abstract:
The present invention greatly reduces the minimum turning radius of an aerial work platform. Drive motors 351, 352 are provided to the driven wheels 33c, 33d of the aerial work platform respectively, so that the driven wheels 33c, 33d can be independently controlled in terms of rotational speed and rotation direction. When the steering angle of steered wheels 33a, 33b is at most a first steering angle (for example, ±6°), constant velocity control is performed, driving both of the driven wheels 33c, 33d in the same rotation direction and at the same rotational speed. When the steering angle exceeds the first steering angle and is at most a second steering angle (for example, ±54°), differential control is performed, reducing the rotational speed of the driven wheel on the inside in the turning direction relative to the driven wheel on the outside in the turning direction. When the steering angle exceeds the second steering angle, counter-rotation control is performed, counter-rotating the driven wheel that is on the inside in the turning direction.
