JPS5945245A - Antitheft device for vehicle - Google Patents

Abstract

PURPOSE:To certainly give antitheft warning even if electricity supply from a battery on a vehicle is cut off, by providing an auxiliary power source in an appropriate place hard to find, to supply electricity to a warning controller which sends out a warning instruction signal when a vehicle stealing act is detected. CONSTITUTION:A warning controller 4 is put into operation by turning on a switch 3. When a theft signal is applied from a sensor 2 to the warning controller 4 in operation, a warning generator means 5 is driven by the controller. An auxiliary power source 6 and a diode 7, which functions to prevent an inverse current, are connected to a line for supplying electricity to the warning controller 4 from a battery 1 on a vehicle. The auxiliary power source 6 is located in a place hard to find, such as the interior of the warning controller 4 or the riding room of the vehicle. As a result, even if electricity supply from the battery 1 is cut off, electricity can be fed to the warning controller 4 from the auxiliary power source 6 to maintain a state of being capable of giving warning.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a vehicle 11'a which is capable of providing theft prevention alarm even if the power supply from the vehicle battery is interrupted.
Mt security prevention device t+=qi3゜In the past, a number of devices have been proposed to prevent theft of offshore vehicles, an example of which is the one shown in Figure 1. In Fig. 1,] is a vehicle battery, 2 is a door switch, foot switch, trunk switch or vibration sensor, and 1 is a sensor that detects vehicle theft, such as an infrared sensor. Praise 1 work Controller 4 can be set to 4L state or activated state, 146 switch, 5 is mouth IJ J! (It is a means of generating a warning with 4 lights and a horn.In this device 1゛C, the switch 3 is not turned on and the 1fi1 warning controller 4 is activated and the anti-theft device is activated. 6゜In this state, theft from detection sensor 2!

It is supplied from the mounted battery J, and furthermore, the jIL mounted battery 1 can be easily attached and detached, and the arrangement is R7 and η, so that the controller 4 can be sued for a false warrant for r1 or for false accusations. Even if there is C, battery 1 or failure A
), or if the cable from the pantry 1 is disconnected from the pantry 1, or if the battery is in a depleted state, that is, in a so-called dead battery state, the controller 4 is reset and alerted. t4 in touch state
There was a problem in that even if the battery was subsequently reconnected, the anti-theft device would not work and the theft movement would not occur.

The present invention has been made in view of the above points, and provides a vehicle theft prevention device that includes an alarm controller that outputs a motion axis command signal when an act of vehicle theft is detected.
In order to ensure theft prevention f4h even if the introduction from the vehicle battery to the alarm controller is interrupted6,
The auxiliary m source for power supply to the dynamic axis controller is installed in thNr, which is difficult to find, such as inside the alarm controller or inside the 'J4L room.

The present invention will not be described below with reference to the drawings. Figure 2 is a block diagram showing an embodiment of the anti-theft device according to the present invention, and the same reference box numbers as in Figure 1 refer to the same numbers. The components are shown. As is clear from a comparison with FIG. 1, in this embodiment, a second power source 6 as an auxiliary source is installed in the power supply line of the alarm controller 4, and a diode 7 is installed in this power supply line to prevent backflow. This is a great continuation of the above. In reality, the source 6 and the diode 7 of the A32 are incorporated into the trailer 4 as shown by the dashed line in the figure. mosquito,
In Figure 2, it is shown externally to make it easier to understand the convergence angle.

The anti-theft device in Figure 2? 41 is basically the same as the device shown in Fig. 1, or the device shown in Fig. 2 is connected to the BT from the on-board battery 1. If power is not supplied continuously from then on, the output state of the t1 signal Ib command of the private controller 4 when the battery 1 is turned off remains unchanged. Therefore, after that, the 1uM battery and the anti-theft device can immediately generate a 4tLs alarm. Auxiliary m source 6 is fed back to Troller 4
Since the power supply deviation is only J, a secondary battery such as a nickel-cadmium battery can be used.

In the above embodiment, since only the controller 4 is configured to be disconnected from the auxiliary source 6, the battery 1 is cut off when an alarm occurs. i1. Controller 4 does not maintain the alarm condition.

Button 3 shows another embodiment of the present invention, in which an auxiliary m source 6 is added to the alarm controller 6 and the alarm means 5 in addition to that of the first embodiment. It is also designed to supply electricity. That is, in the apparatus shown in FIG. 3, the auxiliary power source 6 is configured to start supplying power by the relay 8 in an emergency. When the vehicle battery 1 is disconnected, the coil of the relay 8 is deenergized, and its contact point is connected to the auxiliary power supply 6 side 1.
C is switched, and the power supply to the alarm controller 4 and alarm generator &5 is maintained by the auxiliary m source 6, so the b alarm is also generated. The auxiliary power source 6 used in this embodiment is sufficient to allow the alarm controller 4 and the photoconversion means 5 to continue supplying power for a sufficient period of time.
It may be necessary to use a lead-acid battery with a large JTL, for example. In this case, the auxiliary source 6 is placed in a location where it is difficult to discover the connection between the auxiliary source and the alarm controller, such as inside the passenger compartment, to ensure that no explosion occurs. (
In addition to the on-board battery, the vehicle's anti-theft device outputs a sharpener shaft command signal when a theft is detected, replaces the alarm controller, and reports a crime based on the h alarm command signal. Connect the auxiliary source to a place where it is difficult to find, such as inside the vehicle or inside the vehicle. Since I supplied power from the mains source and continued to use it, m
It is possible to reliably prevent and report injuries.

Claims (1)

[Claims] Vehicle theft? In a device that outputs a W-axis command signal when detecting an accident, the controller outputs a W-axis command signal, and reports theft based on the report command signal. The vehicle theft prevention device is characterized by being installed in a location that is difficult to find, such as inside the controller or inside the vehicle.
