Claim 8:
9. A system for determining a corrected distance dkorr to an authenticator from a point on the vehicle longitudinal axis based on a distance (dr, dl) between at least one antenna arranged on a vehicle side and the authenticator, wherein the corrected distance dkorr is calculated with the system using the formula:, d
      korr
    
    =
    
      
        (
        
          
            d
            
              r
              ,
              l
            
          
          +
          
            
              (
              
                FZB
                2
              
              )
            
            *
            
              (
              
                ∝
                90
              
              )

      *
      
        k
        d
      
    
  
  ,

wherein dr is the calculated distance to the authenticator from an antenna mounted on a right passenger side in or on the vehicle or dl is the calculated distance to the authenticator from an antenna mounted on a left driver side in or on the vehicle,
wherein FZB is a vehicle width,
wherein α is the angle between the longitudinal axis of the vehicle and the authenticator determined in claim 1, and
wherein kd is a correction factor for the corrected distance calculation that is that is pre-stored in the system and is specific to a vehicle type of the vehicle.
