RADIO SIGNAL RESPONSIVE VEHICLE DISABLING SYSTEM

摘要

A selective call module (102), installed in a land vehicle having an engine with an ignition system (118), has a selective call receiver (104), a microprocessor (106) and a non-volatile memory (108). The selective call module is connected to an engine control module (116) of the land vehicle. The microprocessor decodes received selective call signals and causes the selective call module to enter into a shutdown state upon decoding of a shutdown page. In the shutdown state, the selective call module measures the engine speed and immediately shuts down the engine by completely turning off the ignition system if the engine speed is less than a pre-set value. The selective call module gradually shuts down the engine by interrupting the ignition system for gradually increasing durations if the engine speed is greater than the pre-set value.
