  • Control system and control method of vehicle group
    Patent number: 11984025
    Abstract: A control device included in each vehicle composing a vehicle group predicts a vehicle state of a subject vehicle before a traveling regulation point based on speed information of the subject vehicle, light color information of a traffic signal, and distance information between the subject vehicle and an entrance of the traveling regulation point. Based on the vehicle state, it is determined whether a vehicle of which the vehicle state corresponds to an unenterable state is included in the vehicle group. The unenterable state indicates a state where the subject vehicle cannot enter the traveling regulation point before the traffic signal is changed to the yellow light when its speed is maintained at a current speed. When it is determined that the vehicle in the unenterable state is included in the vehicle group, the subject vehicle is controlled such that it does not enter the traveling regulation point.

  • METHOD FOR PRODUCING PLATE PIECE AND PUNCHING MACHINE
    Publication number: 20240149324
    Abstract: A technique disclosed herein relates to a method for producing a plate piece including a partial outline and a remaining outline continuous from the partial outline. The method disclosed herein may comprise removing an outer region external to the partial outline from a plate workpiece by a first punch (first punching process); and punching out an inner region internal to the remaining outline by a second punch from the plate workpiece in which the outer region has been removed while applying a block to a side surface of the plate workpiece along the partial outline (second punching process). In the second punching process, by applying the block to the side surface of the already-formed partial outline, deformation of the partial outline can be suppressed when the inner region internal to the remaining outline is punched out by the second punch.
