Portable device for automotive device control system
First Claim
1. A portable device of an automotive device control system for controlling access to an automobile based on a communication to the automotive device control system comprising:
- a communication means for receiving and sending a signal to the automotive device control system;
a control means for controlling the communication means;
a potential detection means for detecting electrical potential of a battery used to energize the communication means and the control means and a detection control means for controlling detection operation of the potential detection means, wherein the detection control means operates the potential detection means either continuously in a continuous monitor mode or intermittently in an intermittent monitor mode in order to detect electrical potential of the battery, wherein the detection control means operates the potential detection means in the intermittent monitor mode when electrical potential of the battery is equal to or higher than a predetermined switch potential, and wherein the detection control means operates the potential detection means in the continuous monitor mode when electrical potential of the battery is lower than the predetermined switch potential.

Abstract
A portable device for receiving and sending a signal to an automotive device control system includes a communication means for receiving and sending the signal to the automotive device control system, a control means for controlling the communication means, a potential detection means for detecting electrical potential of a battery used to energize the communication means and the control means, and a detection control means for controlling detection operation of the potential detection means. The detection control means operates the potential detection means either in a continuous monitor mode or in an intermittent monitor mode in order to detect potential of the battery. The intermittent monitor mode is used when potential of the battery is equal to or higher than a predetermined potential, and the continuous monitor mode is used when potential of the battery is lower than a predetermined potential.
