Abstract: The vehicle-use electricity management system includes an electricity demand detection means to detect electricity consumed by electrical loads, and an electricity price information generation means to generate electricity price information indicative of a price of electricity supplied to the electrical loads based on the electricity demand. At least one of the electrical loads includes an electricity consumption ability determination means to determine whether electricity supplied to the own electrical load can be consumed unconditionally based on comparison between the electricity price information received from the electricity price information generation means and electricity consumption ability information stored in the own electrical load, and an electricity consumption control means to control an amount of electricity consumed by the own electrical load based on a determination result made by the electricity consumption ability determination means.

Abstract: An engine control system checks whether communication is established between a mobile unit carried by a driver and a shift lever, a brake pedal and a steering wheel through a human body of the driver. If the communication is not established, the engine control system prohibits an automatic start of an engine even when a predetermined manipulation required for starting the engine is detected. As a result, the engine is prohibited from being started automatically against the driver's intention.
