  • Publication number: 20190210805
    Abstract: A method includes acquiring starting position information of moving bodies; acquiring destination position information of movement destinations; acquiring path information indicating paths on which the moving bodies can move; calculating, for each moving body, a minimum movement amount required for the moving body to move on a path from the starting position to each movement destination, based on the starting position information, the destination position information, and the path information; allocating a movement destination not allocated to any moving body to a moving body that has a minimum movement amount being the smallest of the minimum movement amounts and that has no allocation of any movement destination; further allocating, when there is a movement destination not allocated to the moving body on a movement route, the not-allocated movement destination to the allocated moving body; and determining movement routes of the moving bodies based on the allocation.

  • Patent number: 10262823
    Abstract: A relay control method is provided for controlling an in-vehicle motor that includes a steering angle main control module. The main control module has a power supply relay is connected to a battery, a motor drive circuit connected to a fixed contact of the power supply relay via a bus bar, and a phase relay connected to the motor drive circuit via a bus bar. The motor drive circuit contacts a heat radiation part that has a higher thermal conductivity than the power supply relay. After the ignition is turned off and with the switches for the power supply relay and the phase relay remaining in the on state, a motor energization control is performed for maintaining a rotation stop state in the motor for a predetermined time, and after the predetermined time has elapsed, the switch of the power supply relay is switched to off.

  • Publication number: 20180202500
    Abstract: Protruding portions have an agitation face on the side surface thereof to agitate or dam hydraulic oil. An oil chamber defining portion has a supply hole that is allowed to supply the hydraulic oil from outside a hydraulic oil chamber by communicating with the hydraulic oil chamber from the rotational center side. When the protruding portions abut against the oil chamber defining portion so that the capacity of the hydraulic oil chamber is minimized, the supply hole faces, in a radial direction, a flow passage that is surrounded by circumferentially adjacent ones of the protruding portions, an oil chamber defining portion, and a piston.
