US 5,247,564 A · Adaptive vehicle alarm detection and reporting system

Abstract

A cellular mobile radiotelephone (CMR 12) which detects and reports security breach conditions is disclosed. The CMR (12) includes a remotely programmable unit (RPU 48) in which alarm parameter data (1200) may be recorded from a remote programming (RP) host (22). An input (54) may be adapted to receive a vehicle alarm system (26) output. When the alarm system activates, a Mode 1 Alarm procedure (1700) is performed. If the alarm indication is deemed genuine, the CMR (12) automatically places a call to a security service (28). When a vehicle ignition signal (52) has just turned "on", a Mode 2 Alarm procedure (1800) is performed. A user is given a period of time, which is established remotely (1214), to enter a disarming code. If the disarming code is not entered in time, a genuine alarm event is assumed, and the CMR (12) places a call to the security service (28). In placing calls to the security service (28), numerous alarm parameters are established remotely. Thus, multiple call attempts to multiple telephone numbers (1216-1218), repeat call attempts for multiple iterations (1220), delays between call attempts (1222), diverse data formats (1224-1226), and multiple security breach reporting intervals (1228) are programmed remotely as needed to achieve a desired level of security protection.

Dependent claims

A cellular radiotelephone system for use in a vehicle having an ignition terminal adapted to carry an ignition signal, said system comprising:

a cellular mobile radiotelephone transmit/receive unit (TRU) for engaging in first and second phone calls;
remote programming control means, coupled to said TRU, for receiving and recording alarm parameters from said TRU during said first phone call;
a vehicle alarm system having an output signal which activates to indicate a security breach condition;
user input means for generating a disarming signal in response to a physical manipulation of said user input means by a user;
timing control means, coupled to said ignition terminal, for determining a disarming duration which begins substantially at activation of said ignition signal and continues for a period of time established by said alarm parameters;
and
alarm detection control means, coupled to said vehicle alarm system, to said TRU, to said user input means, and to said timing control means, for instructing said TRU to place said second call to a telephone number when said security breach condition occurs, said telephone number being defined by said alarm parameters, and for instructing said TRU to place said second call to said telephone number when said disarming signal is not generated prior to expiration of said disarming duration.

4 more elements

A method of operating a cellular telephone having a keypad for receiving user input, said cellular telephone being installed in a vehicle having a vehicle ignition terminal and a vehicle alarm system, and said method comprising the steps of:

a) receiving one or more programming phone calls which communicate alarm parameters to said cellular telephone, said alarm parameters including data defining a predetermined duration and a telephone number;
b) monitoring said vehicle alarm system to detect an alarm signal which indicates a security breach condition;
c) monitoring said vehicle ignition terminal to determine when vehicle ignition becomes activated;
d) monitoring said keypad to determine whether a predetermined sequence of keys from said keypad is activated;
e) monitoring time to determine when said predetermined duration transpires after activation of said vehicle ignition;
and
f) placing a call to said telephone number when said predetermined duration transpires prior to determining said predetermined sequence at said keypad or when said alarm signal is detected.
