Remote immobilisation of moving powered vehicles

摘要

A system to achieve the disablement of moving stolen vehicles by remote means addresses e.g. a paging receiver in the vehicle by radio, causing a reduction of power delivered to propel the vehicle, e.g. by modifying the signal from the air flow sensor A.F.S to the engine control unit E.C.U. Successive pager calls cause successive reductions of power (or one call may be sufficient to cause progressive reduction of power) for safe speed reduction.
