Abstract
A transient increase or decrease of power supplied to a reconfiguration circuit to be a logic circuit whose circuit configuration can be changed is reduced. An autonomous traveling control ECUhas a reconfiguration circuita main power supply circuitan auxiliary current source circuitand a function control unitThe reconfiguration circuitis a reconfigurable logic circuit. The main power supply circuitsupplies a power supply voltage to the reconfiguration circuitThe auxiliary current source circuitincreases or decreases a current supplied from the main power supply circuitto the reconfiguration circuitThe function control unitdetermines an operation mode of the reconfiguration circuiton the basis of a mode determination signal input from the outside and indicating a traveling mode of a vehicle, and controls a reconfiguration of the reconfiguration circuiton the basis of a determination result. The auxiliary current source circuitincreases or decreases the current supplied to the reconfiguration circuitin accordance with a load variation of the reconfiguration circuiton the basis of an auxiliary current control signal for giving an instruction on an increase or decrease of the current supplied to the reconfiguration circuit
