1. be used for the equipment of positioned vehicle electron key, described equipment comprises:

  • Key card, be used for receiving low frequency signal, determine the low frequency signal intensity value of the low frequency signal received and provide radio-frequency responsive signal, a part for response signal comprises the low frequency signal intensity value determined;

    Central authorities'"'"' low-frequency antenna, is positioned at the center of the operator'"'"'s compartment of vehicle and the operator'"'"'s compartment near vehicle, is used for substantially also substantially in the operator'"'"'s compartment of vehicle, providing low frequency signal throughout the operator'"'"'s compartment of vehicle;

    Controller, is used for from key card received RF response signal, by the low frequency signal intensity value determined compared with predetermined threshold, and determines key card whether at the cabin interior of vehicle according to comparing;

    AndVehicle motor hill holder, in response to described controller, described controller controls described hill holder in response to described comparison,Wherein, the low frequency energy that described controller comprises pre-stored maps, and wherein said controller is by compared with mapping the low frequency signal intensity signal value determined with the low frequency energy of pre-stored, carries out key card whether in the determination of the cabin interior of vehicle.
