ACTUATOR CONTROL DEVICE AND WORK VEHICLE
First Claim
1. An actuator control device comprising:
- an actuator,an operation unit that receives an operator'"'"'s operation of driving the actuator,a storage unit that stores a drive control characteristic which is represented by a characteristic line monotonically increasing on a two-dimensional plane defined by a first axis which represents the operation amount of the operation unit and a second axis which is orthogonal to the first axis and represents the driving speed of the actuator, the drive control characteristic representing the driving speed corresponding to the operation amount, anda control unit that drives the actuator based on the drive control characteristic stored in the storage unit,wherein the control unit performs;
a first reception process in which inputs of values of a minimum operation amount and a maximum operation amount of the operation unit on the first axis for driving the actuator, and a value of a maximum driving speed on the second axis, which is the actuator driving speed corresponding to the maximum operation amount, are received,a second reception process in which designations of the shape of the characteristic line are received,a determination process in which a function representing a characteristic line that links a first point, which corresponds to the minimum operation amount and the driving speed of 0, and a second point, which corresponds to the maximum operation amount and the maximum driving speed to form the designated shape, is stored in the storage unit as the drive control characteristic,a drive control process is performed in which, in response to operation of the operation unit, the actuator is driven at the driving speed corresponding to the operation amount specified by the drive control characteristic stored in the storage unit, andthe characteristic line which is designated in the second reception process is a single straight line or a curve which does not include an inflection point.

Abstract
[Problem] To provide an actuator control device with which desired drive control characteristics can be obtained by means of a simple operation.
[Solution] This device performs: a reception process (S12) in which designations of a minimum operation amount and maximum operation amount of an operation unit for driving an actuator, and a maximum driving speed which is the actuator driving speed corresponding to the maximum operation amount are received; a determination process (S13, 14) in which a function representing a characteristic line that links a first point, which corresponds to the minimum operation amount and the driving speed of 0, and a second point, which corresponds to the maximum operation amount and the maximum driving speed, is stored in a storage unit as a drive control characteristic; and a drive control process in which, in response to operation of the operation unit, the actuator is driven at a driving speed corresponding to the operation amount specified by the drive control characteristic stored in the storage unit.
