MOVING MACHINE CONTROL PROGRAM AND MOVING MACHINE CONTROL DEVICE
A moving machine control program causes a computer to execute: acquiring requested external force regarding an actuator; reading out a reference kinetic model that defines moving machine behavior exhibited when the actuator generates external force corresponding to the requested external force; calculating, as requested moving machine behavior, the moving machine behavior exhibited when the actuator generates the external force corresponding to the requested external force, in accordance with the reference kinetic model; measuring actual moving machine behavior during traveling of the moving machine; correcting the requested external force such that the actual moving machine behavior measured in the measuring step approaches the requested moving machine behavior calculated in the calculating step; and controlling the actuator based on the corrected requested external force.
Braking device for vehicle
A braking device includes: a reservoir; a master cylinder in which when the amount of operation performed on a brake pedal reaches or exceeds a predetermined amount, a port communicating between a pressure chamber and the reservoir is cut off and hydraulic pressure corresponding to the brake pedal operation amount is generated; a hydraulic pressure unit for adjusting the wheel cylinder hydraulic pressure; and a control unit for controlling the hydraulic pressure unit. The control unit determines, based on a temperature-related value related to the temperature of a friction member pressed by the wheel cylinder hydraulic pressure against a rotating member fixed to a wheel, whether the friction member is in a fade state. When the friction member is in a fade state, the control unit controls the hydraulic pressure unit to suction brake fluid from the reservoir through the port, and is fed to the wheel cylinder.
