Problems solved by technology

In addition, when an obstacle moves and approaches the electric wheelchair from a blind spot in the detection area, the maximum speed limit of the electric wheelchair is released due to the obstacle leaving the detection area, so the possibility of collision between the electric wheelchair and the obstacle cannot be reduced.

Abstract

The present invention provides that, in a mobile body equipped with a detection device for detecting an obstacle, the detected obstacle relatively moves due to being in an area detected by the detection device, and departs from the area to approach the mobile body. A mobile object that can travel safely and securely. A control device for an electric wheelchair as a mobile body includes: an obstacle presence / absence detection unit that extends in a first region extending along a traveling direction of a predicted traveling path of the electric wheelchair predicted based on input information from the operating device and at a distance from the electric wheelchair. The presence or absence of an obstacle is detected in a second area as a peripheral area within a predetermined distance; and the driving amount limiting unit is detected as being in at least any one of the first area and the second area by the passing obstacle presence / absence detection unit. When there is an obstacle in the area, the drive amount of the drive unit is limited to the limit drive amount.

Description

technical field [0001] The present invention relates to a mobile body, and particularly relates to a mobile body that travels through the operation of passengers. Background technique [0002] A mobile body disclosed in Patent Document 1 is known as one form of a mobile body that moves by being operated. As in Patent Document 1 figure 1 as well as figure 2 As shown, the mobile body is, for example, an electric wheelchair, which includes an object detection sensor 19 for detecting objects in the detection area, a motor 5 for driving the wheels, and a control circuit 25 for controlling the driving amount of the motor 5 to control the travel of the electric wheelchair. The control circuit 25 includes drive control means that limits the maximum speed of the electric wheelchair when a detection signal from the object detection sensor 19 is input. Thereby, the possibility of a collision between the electric wheelchair and an obstacle such as a pedestrian can be reduced. [00...
