Abstract

An antitheft device 91 for preventing the theft of a vehicle M is provided with: a means for determining whether an approaching object T exists on the basis of the information obtained from a peripheral monitoring sensor 93 monitoring the periphery of the vehicle M; a means for determining whether the approaching object T to the vehicle M is a suspicious individual on the basis of the information obtained from a motion sensor 94 for monitoring the periphery of the vehicle M and / or the inside of the vehicle M when it is determined that the approaching object T to the vehicle M exists; and a means for taking measures such as lighting of an indicator 38 when it is determined that the approaching object T to the vehicle M is the suspicious individual.

Description

technical field [0001] The invention relates to an anti-theft device, a monitoring device and an anti-theft system, in particular to an anti-theft device aimed at preventing vehicles from being stolen, a monitoring device for monitoring vehicles, and an anti-theft system. Background technique [0002] The number and incidence of vehicle theft and vehicle prying cases are increasing day by day. Therefore, in recent years, various anti-theft devices (such as the devices disclosed in Japanese Patent Laid-Open Publications No. Hei 11-7561 and No. 2000-231691) related to preventing vehicle theft (including vehicle prying) have been proposed. [0003] FIG. 29 is a block diagram schematically showing main parts of an anti-theft system equipped with a conventional anti-theft device. 1 represents anti-theft device among the figure, and anti-theft device 1 is provided with CPU3, the microcomputer 2 of ROM4 and RAM5 is housed, memory is set to the EFPROM6 of the ID code that each vehi...
