Abstract

investment for theft prevention of vehicles by radio with vehicle-side recipients for the Vehicle locking commands that activate an immobilizer, characterized by a delay circuit (10, 14) with variable delay time in the output of the receiver, which is connected to operating data sensors (8, 9) of the vehicle and the lock command only when the operating setpoints are undershot releases.

Description

  • object of the property right is a system for theft prevention of vehicles on the radio path.
  • Out the radio show 20/1994, page 36/37, it is known, if required by one outside the vehicle central station a blocking command for activation an immobilizer of a motor vehicle to radiate through this to receive a receiver tuned to the central transmitter in the vehicle and to the immobilizer.
  • In the DE 94 11 560 U1 or WO 93/17895 A1 each systems for theft prevention of vehicles according to the preamble of claim 1 are described with a delay circuit. Corresponding systems for theft prevention of vehicles according to the preamble of claim 1 are described in the DE 93 08 721 U1 and U.S. Patent 5,370,201.
  • Advantages of invention
  • The Invention differs from this prior art by the features in the characterizing part of claim 1.
  • The Invention has the advantage that in the execution of the Lock command takes into account the current driving situation of the vehicle can be and a threat the vehicle occupants and other road users by the activation the immobilizer is avoided.
  • In the claims 2 to 5 are advantageous embodiments characterized the invention.
  • drawing
  • at the further explanation The invention is referred to the drawing. It shows
  • 1 a block diagram of a system according to the invention.
  • description an embodiment
  • The vehicle-mounted receiver of the inventive system for theft prevention of vehicles on the radio path comprises a vehicle antenna 1 , a radio receiver 2 and an evaluation circuit 3 ,
  • The radio receiver 2 must be designed for the frequency range in which the central transmitter works and possibly sends out a blocking command. As a central transmitter, a terrestrial radio transmitter can serve, which also emits signals from the radio data system (RDS) at the same time as its radio program. Among other things, it also provides a paging channel, which can also be used for the transmission of blocking commands provided here.
  • But also other transmitter systems used for transmission are designed by pagers, z. B. Cityrufsender, Eurosignalsender, can for the transfer Lock commands are eligible if they have sufficient range of their reception.
  • In the to the radio receiver 2 connected evaluation circuit 3 the transmission of a lock command for the individual vehicle is detected. Such a locking command can, for. B. consist of the vehicle registration. The system of vehicle registration ensures that each vehicle can be addressed individually without further effort for the identifier.
  • On the question of the proof of the authorization to initiate the transmission of a locking command for an individual vehicle, and the procedures for initiating the transmission of a locking command need not be discussed here, since they are to be expected in the prior art. It is essential that the actual receipt of a locking command for the individual vehicle in the evaluation circuit 3 is recognized.
  • The evaluation circuit 3 is with a switch block 4 connected, which includes the entire on-board electronics for engine control.
  • Depending on the vehicle type, the effort in the on-board electronics varies. For engine control, the on-board electronics optionally intervene in the ignition circuit 5 or in the control of the fuel supply 6 or in both.
  • The ignition circuit 5 also includes the starter 7 of the vehicle, but only after the engine is switched off, ie usually only after a long break, used again.
  • The on-board electronics 4 is connected to various sensors, including speed sensors 8th and / or with speed sensors 9 for recording the vehicle speed (speedometer cable). The output signals of these sensors Provide information about whether the wheels of the vehicle are rolling or resting at the time the sensors are polled. For the inventive system, the output signals of the sensors are important, indicating a resting of the wheels.
  • In the system according to the invention is the on-board electronics 4 for optionally desired delay of the locking command as a delay circuit an AND stage 10 upstream of which one input via an OR stage 11 with one of the sensors 8th or 9 is connected and whose second input to the output of the evaluation circuit 3 is connected while the output of the Andstufe 10 with an input of the on-board electronics 4 is connected, from which this can silence or switch off. The on-board electronics 4 usually includes a microprocessor, which is programmed according to the invention such that the state of the output of the Andstufe 10 is queried regularly in sufficiently short time intervals.
  • In the output of the evaluation circuit 3 can be a memory 12 lie in which a detected lock command can be cached for a long time, if z. B. transmitter side for the transmission of the locking command only a short period of time is available.
  • The recognized and optionally in the memory 12 Stored locking command can be due to the switching on the Andstufe 10 only be forwarded to the on-board electronics when the wheels stop rolling. This ensures that the engine is not blocked at high speed or even in an overtaking maneuver. If the wheels have come to a standstill, then the engine can be switched off without risk to the occupants and other road users. The vehicle itself may prove to be an obstacle to traffic, but this will give the stationary vehicle more attention.
  • By other sensors and associated with these Andstufen can the desired engine shutdown be further delayed in those traffic situations that are accident-prone, if the vehicle is longer stop.
  • As an example, in the 1 a sensor 13 indicated for not turning on the left flashing light. A standing left turn should not block the road longer than necessary. The output signal of this sensor is therefore one of the input signals for another AND stage 14 whose second input is connected to the output of the first stage 10 connected is. Only the output of the further Andstufe 14 is then with the shutdown input of the on-board electronics 4 connected.
  • To safeguard the other road users, the output of the first stage can also be used with the on / off switch of the hazard warning lights 15 be connected so that the moment the shutdown of the on-board electronics 4 the other road users are warned.
  • It has proved to be very effective when the hazard warning lights ( 15 ) directly from the output of the evaluation circuit ( 3 ) is turned on instantaneously upon receipt of a lock command.
  • Instead of the hazard warning lights can also used other means for signaling a disturbance to the outside become.
