IN-VEHICLE DEVICE AND VEHICULAR COMBINED CONTROL SYSTEM
First Claim
1. An in-vehicle device for a vehicular combined control system, comprising:
- first control means configured for a smart entry system and to conduct radio communication with a portable device carried by a user of a vehicle to conduct authentication required to permit execution of predetermined controls in the vehicle;
second control means configured for a tire pressure monitoring system and to conduct radio communication with tire pressure detecting means thereby to acquire information related to the conditions of the tires from the detecting means; and
receiving means configured to switch over any one of a first operation mode for receiving the information that is transmitted from the portable device to output the information to the first control means, and a second operation mode for receiving the information that is transmitted from the detecting means to output the information to the second control means,wherein the receiving means is configured to switch over to the first operation mode when an output signal from the first control means turns on irrespective of ON/OFF condition of an ignition switch of the vehicle, and switch over to the second operation mode when the ignition switch of the vehicle is ON and the output signal from the first control means turns off,wherein the first control means is configured to turn on the output signal intermittently or based on a given trigger, and input information from the portable device which is output from the receiving means when the output signal turns on, andwherein the second control means inputs the information from the detecting means which is output from the receiving means, when the ignition switch of the vehicle is ON and the output signal from the first control means is OFF.

Abstract
A vehicular combined control system has functions of a smart entry system and a TPMS. A smart ECU turns on the output of a voltage signal terminal intermittently or in response to a given trigger. When the output of the voltage signal terminal turns on, a RF receiver section receives information from a portable device regardless of the ON/OFF state of an ignition switch to transmit the information to the smart ECU. When the ignition switch is ON and the output of the voltage signal terminal turns off, the RF receiver section receives information from tire sensors to transmit the information to a TPMS microcomputer.
