Title:
STEP DETECTION DEVICE AND STEP GETTING-OVER DEVICE
Document Type and Number:
Japanese Patent JP2017003383
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a step detection device for detecting a step using contact-type detection means and a step getting-over device for getting over a step which mounts the step detection device thereon.SOLUTION: An acceleration sensor 300 which is attached to a portion contacting a rotary axis of a drive wheel 101, and detects acceleration in two-axis directions forming a right angle in a plane which is vertical to the rotary axis of the drive wheel, is provided as a step detection device. When a step on a track and the drive wheel contact, a resistance direction angle is determined from the two-axis direction component of resistance acceleration obtained from the acceleration sensor, then a height h of the step is estimated based on the resistance direction angle. In a step getting-over device, the step detection device is provided, and drive wheels 101, 103 are arranged on a front side of a front wheel 201 and a rear side of a rear wheel 202 of a bogie, and actuators 102, 104 for changing a height of the drive wheels, are provided, and based on a value of the resistance direction angle θ, it is determined whether a step which the front side drive wheel contacts, is in a direction of rising to a travel direction of the bogie, or in a direction of lowering, then, the actuators are operated by the height of the step.SELECTED DRAWING: Figure 1
