  • Article transport facility
    Patent number: 11897698
    Abstract: A transport vehicle control system restricts a travel speed of an article transport vehicle to less than or equal to a restrictive speed prescribed in advance, in a case where a temperature sensor detects that the temperature of a regenerative resistor is greater than or equal to a first temperature set to a higher temperature than a steady temperature range which is a temperature range of a steady state prescribed in advance, and disconnects the connection between a power supply unit and a travel motor with a switch, in a case where the temperature sensor detects that the temperature of the regenerative resistor is greater than or equal to a second temperature set to a higher temperature than the first temperature.
