Abstract

An onboard-equipment control apparatus controls activation of an onboard apparatus such as an air conditioner and termination of the operation of the onboard apparatus in order to prevent an onboard battery from running out of residual electric charge in advance. Upon detection of a state in which an onboard radio apparatus is not capable of receiving a termination command from a cellular phone or the cellular phone is not capable of transmitting a termination command to the onboard radio apparatus while the air conditioner is in operation, the onboard-equipment control apparatus forcibly terminates the operation of the air conditioner even before a termination condition is satisfied. Thus, the onboard battery can be prevented in advance from running out of accumulated electric charge required for operating the activated air conditioner thereafter.
