MOVEMENT-ASSISTING DEVICE

摘要

An assistive control means provided in a movement-assisting device has a probability determining unit for determining whether the detection probability according to a first detection signal is high, and a same-object-identifying unit for identifying whether other objects specified respectively by the first detection signal and a second detection signal are the same objects. The assistive control means controls the operation of an assistive means only when the detection probability is determined to be high and when the objects are identified as being the same object. Consequently, a behavior-stabilized assistive operation can be continued even if the detection probability of one of the detection signals is low when the other objects are detected on the basis of two types of detection signals.

1. A movement assisting device including an assisting unit configured to assist movement of a physical object or a living body as a mobile object, comprising:
a first detecting member configured to acquire a first detection signal indicative of another physical object that exists in vicinity of the mobile object; a second detecting member configured to acquire a second detection signal indicative of the other physical object, and to use a same or a different detection system as the first detecting member; and an assistance control member configured to implement a process in the mobile object to cope with the other physical object, by controlling an assisting operation performed by the assisting unit based on the first detection signal and the second detection signal that are acquired respectively by the first detecting member and the second detecting member; wherein the assistance control member includes: an accuracy determining unit configured to determine whether or not detection accuracy in accordance with the first detection signal is high; and a same object identifying unit configured to identify whether or not the other physical objects specified respectively by the first detection signal and the second detection signal are the same object; wherein, in a case it is determined by the accuracy determining unit that the detection accuracy is greater than a predetermined value, the assisting operation is capable to be controlled based on only a detection result obtained from the first detecting member, and in a case it is determined by the accuracy determining unit that the detection accuracy is less than or equal to the predetermined value, the assisting operation is controlled only if it is further identified by the same object identifying unit that the other physical objects are the same object.
