Claim Text:
1. A vehicular control system for a vehicle, the system comprising: a portable terminal operated with an embedded battery and to be carried by a user; and an in-vehicle apparatus mounted in the vehicle, the portable terminal performing a wireless communication with the in-vehicle apparatus in a wave-detection state where the portable terminal detects a transmission electric wave that is transmitted from the in-vehicle apparatus, the portable terminal selecting either a sensitivity periodic-switchover mode or a sensitivity fixed mode, to change an operating power of the portable terminal, the sensitivity periodic-switchover mode switching periodically a sensitivity switchover of a detection sensitivity for detecting the transmission electric wave from the in-vehicle apparatus between a first sensitivity and a second sensitivity, the second sensitivity having a detection area of the transmission electric wave greater than a detection area of the first sensitivity, the second sensitivity being higher than the first sensitivity, the sensitivity fixed mode fixing the detection sensitivity to the first sensitivity, the sensitivity periodic-switchover mode using the operating power greater than the operating power that the sensitivity fixed mode uses, the sensitivity periodic-switchover mode being selected to be performed until the portable terminal is verified by the in-vehicle apparatus in the wave-detection state, the sensitivity fixed mode being selected to be performed, by being switched from the sensitivity periodic-switchover mode to reduce the operating power, either
