  • Publication number: 20250132977
    Abstract: A central ECU serving as a communication control device is provided with a memory and a processor coupled to the memory, the processor receives a change notification relating to a change of an intra-vehicle network communication setting from a center server; and determines whether or not new setting information of the intra-vehicle network that is required in association with the change notification is memorized at at least one of the central ECU and an Ethernet switch. When it is determined that the setting information is memorized at neither the central ECU, or the Ethernet switch, the processor requests the setting information from the center server.

  • Patent number: 11118985
    Abstract: A load sensor to be used in an electromechanical brake system includes a flange member capable of deflecting when receiving, at a load receiving portion, a load from the axially front side; a support member capable of supporting the flange member from the axially rear side, at a support portion displaced from the load receiving portion in a radial direction orthogonal to the axial direction; and a displacement detecting mechanism configured to detect the amount of relative movement between the flange and support members. A variable detection sensitivity mechanism enables the relative movement amount with respect to the change of the load applied to the flange member to be larger in a low load range in which the load is equal to or lower than a predetermined load value than in a high load range in which the load is higher than the predetermined load value.

  • Patent number: 10808781
    Abstract: In an electric linear motion actuator, while an axially forward load is not being applied to an object by an outer ring member, a preload is applied to a frictionally coupling surface by an elastic member, and, when the axially forward load is applied to the object by the outer ring member, an axial load applied to the frictionally coupling surface decreases by an amount equal to the axially rearward reaction force which the outer ring member receives from the object. The electric linear motion actuator includes a load sensor for supporting, through planetary rollers and a carrier, the axially rearward reaction force. The load sensor is arranged such that any change in magnitude of an axially forward load applied through a snap ring will not affect the value of the axially rearward reaction force detected by the load sensor.
