Method and security apparatus for validating an authorization for locking and unlocking and/or using an object
First Claim
1. A method for validating an authorization for locking and unlocking and/or using an object, comprising the steps of:
- sending out a request signal by at least one transmit and receive unit at the initiation of a control device, andif a moving and in particular portable code generator receives this request signal, sending back a reply signal,analyzing said reply signal being by the control device following receipt in the transmit and receive unit, andif an authorization is present and confirmed, outputting by the control device at least one control command in the object or motor vehicle, depending on a relevant distance of the code generator from the object or motor vehicle and depending on a location in a relevant detection zone around the object or motor vehicle,carrying out a series of distance measurements,calculating an associated quality value by a mathematical function in each case for the measuring results of said distance measurements, wherein only those measured values which fall below a certain quality value as a threshold value are accepted for an analysis in respect of initiating a distance-related function.

Abstract
Taking as a starting point known security apparatuses and their methods for distance-dependent initiation of functions in or at an object, the reliability of distance measurements is essentially increased by carrying out a series of distance measurements, an associated quality value (G) being calculated by a mathematical function in each case for the measuring results (M1–M5, R1, R2) of said distance measurements. Only those measured values which fall below a certain quality value (Krit) as a threshold value are generally accepted for an analysis in respect of initiating a distance-related function. Developments provide for selecting measured values beforehand with reference to a level measurement, in order to further increase the reliability, or applying methods of statistical analysis subsequently.

- 10. A security apparatus for validating an authorization for locking and unlocking and/or using an object, comprising a control device and a memory arranged in the object, said control device being connected to at least one transmit and receive unit, wherein the transmit and receive unit is operable to transmit a request signal to a remote code generator when initiated by the control device, wherein the control device is further operable to calculate a distance of the code generator to the respective transmit and receive unit and operable to determine an authorization, wherein if an authorization is present and confirmed depending on a relevant distance of the code generator from the object or motor vehicle and depending on a location in a relevant detection zone around the object or motor vehicle, at least the control device is operable to output a control command in the object or motor vehicle, wherein the apparatus comprises means to analyze a reply signal from the code generator, and means to calculate an associated quality value by a mathematical function in each case for the measuring results of said distance measurements, wherein only those measured values which fall below a certain quality value as a threshold value are accepted for an analysis in respect of initiating a distance-related function and wherein adjustment parameters and threshold values for the quality criterion and/or a level are permanently stored in the memory of the security apparatus.
