A vehicle includes an electric power source, a load configured to be supplied electric power from the electric power source, a relay provided between the electric power source and the load, and a processor. The processor is configured to control the relay to a conductive state based on a predetermined drive instruction. The processor is configured to acquire a value of current flowing through the relay and a value of voltage applied to the relay after a predetermined amount of time elapses following conduction of the relay based on the drive instruction. The processor is configured to transmit the value of the current and the value of the voltage that are acquired to an external of the vehicle.

A luminance control device and a luminance control method for controlling luminance of a light emitting member are provided in order to reduce the amount of information to be stored while preventing the user from feeling uncomfortable. The CPU divides by the interpolation division number a value obtained subtracting the reference duty ratio from the reference duty ratio so as to calculate an interpolation variation width, and integrates the interpolation variation width to the reference duty ratio every time the interpolation period elapses, and the variation width in the luminance of the LED is therefore reduced, preventing users to feel uncomfortable, which allows for suppressing the amount of information to be stored.

Provided are an overcurrent protection device and an overcurrent protection system which can provide time differences among the timings for executing the retry operations among a plurality of overcurrent protection devices connected to a common power supply. When a battery voltage (VBA) becomes a value equal to or lower than a threshold voltage after an FET (Q) of an IC circuit (-) is turned on, all FETs (Q) of the respective IC circuits are turned off, and a time until the battery voltage (VBA) reduces to a value lower than a threshold voltage after the turning-on of the FET (Q) is clocked. When the time is smaller than 400 &#x3bc;sec, the count value N is incremented. Further, turning-on of the FETs (Q) is repeated after the lapse of the standby time (Tp) set randomly. When the count value N reaches 7, the FET (Q) of the IC circuit-is held in the turned-off state. Accordingly, only the load-driving circuit at which the dead short occurs can be stopped and the driving of the other load-driving circuits can be continued.
