  • Patent number: 12280759
    Abstract: A vehicle brake system includes a first fluid pressure generating device for generating a fluid pressure according to a brake operating amount, a second fluid pressure generating device for generating a fluid pressure by moving a piston with an electric actuator, and a switching valve switchable between a first state allowing communication between the first fluid pressure generating device and a vehicle behavior stabilizing device and a second state allowing communication between the second fluid pressure generating device and the vehicle behavior stabilizing device. A control device places the switching valve in the second state during execution of automatic brake control, and places the switching valve in the first state when a predetermined abnormality occurs in the vehicle, except that the control device places the switching valve in the second state when an abnormality including inability of the second fluid pressure generating device to generate the fluid pressure occurs.

  • Publication number: 20240384997
    Abstract: A control system is for issuing a control instruction to at least one autonomous mobile unit. The control system sets a departure point and an arrival point for the autonomous mobile unit, generates route information regarding the autonomous mobile unit from the departure point and the arrival point, converts location information defined by a coordinate system capable of specifying a location in a space into unique identifier information in a format that identifies, using a unique identifier, state-related information and time-related information regarding an object present in the space defined by the coordinate system, and communicates with the autonomous mobile unit. The control system generates route information from any set departure point and any set arrival point, and converts location information regarding each point included in the route information into the unique identifier to express the route information using the unique identifiers.

    Abstract: A vehicle brake system includes a switching valve switchable between a first state allowing communication between a first fluid pressure generating device and a frictional brake and a second state allowing communication between a second fluid pressure generating device and the frictional brake. The second fluid pressure generating device generates a fluid pressure by moving a piston with an electric actuator, and has a fluid pressure supply port connected to the switching valve and an atmosphere opening port connected to a reservoir tank. When, due to a failure, the switching valve becomes a third state in which the switching valve makes each of the first fluid pressure generating device and the second fluid pressure generating device communicate with the frictional brake, a control device controls the second fluid pressure generating device to close the atmosphere opening port with the piston.
