Japanese Patent JP6762904
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a battery for a vehicle from wearing even when a reservation operation is performed many times.SOLUTION: A door control system 100 is composed of an in-vehicle control unit 10 and a portable device 20. When a UHF reception part 11 of the in-vehicle control unit 10 receives a reservation signal transmitted by a UHF transmission part 22 of the portable device 20, a reservation processing unit 15 performs reservation processing and an LF transmission unit 122 starts transmission of a response request signal. When the portable device receives a response request signal, the UHF transmission part 22 transmits a response signal. When the UHF reception part 11 receives a response signal, a control unit 13 performs unlocking of a door and/or opening of the door. When the UHF reception part 11 receives a reservation signal again before receiving a response signal and a determination unit 17 determines that the reception status of the reservation signal meets predetermined conditions, the LF transmission unit 122 stops transmission of a response request signal.SELECTED DRAWING: Figure 1
