  • VEHICLE POWER SUPPLY SYSTEM AND CONTROL METHOD OF VEHICLE POWER SUPPLY SYSTEM
    Publication number: 20240132147
    Abstract: A vehicle power supply system includes a power source control device that executes a process of switching a connection state of a driving circuit to the main power source and an auxiliary power source including; a process of switching the connection state so as to transition to a backup state as a voltage decrease of the main power source occurs, and a process of switching the connection state so as to transition to a normal state as the voltage decrease of the main power source is resolved. After a voltage decrease of the main power source occurs, a turning-side control device of a steering control unit sets an output-limited state for a turning-side motor. The output-limited state is canceled upon the power source control device completing switching of the connection state so as to transition.

  • Communication control device and communication control method
    Patent number: 8542651
    Abstract: In a communication system of a subscriber extension line system, there is provided a communication controller whereby the load of an unnecessary process to be applied on a communication controller relating to a destination of a mobile telephone is eliminated and the processing efficiency for communication control is enhanced. In a D-RNC which controls the communication of the mobile telephone and which is commonly connected with an S-RNC, the mobile telephone moves while maintaining the communication with the S-RNC. When the mobile telephone enters a cell relating to the D-RNC, the control data is transmitted or received between the S-RNC and the node for managing the mobile telephone.
