Title:
ELECTRONIC CONTROL APPARATUS, IN-VEHICLE SYSTEM, AND POWER SUPPLY CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2018/096767
Kind Code:
A1
Abstract:
The present invention reduces transient increases/decreases in the power to be supplied to a reconfigurable circuit which is a logic circuit with a changeable circuit configuration. An autonomous travel control ECU 201 has a reconfigurable circuit 209, a functional control unit 207, a power supply circuit 211, and a power supply control unit 206. The reconfigurable circuit 209 is a logic circuit that can be reconfigured. The functional control unit 207 determines the operation mode of the reconfigurable circuit 209 on the basis of a mode determination signal and controls the reconfiguration of the reconfigurable circuit 209 on the basis of the determination result. The power supply circuit 211 supplies power to the reconfigurable circuit 209. The power supply control unit 206 controls the power supply circuit. The power supply control unit 206 controls the load current generated by the power supply circuit 211 before a the load of the reconfigurable circuit 209 fluctuates, on the basis of power supply control information that is information for controlling the power supply circuit 211.
