1. One kind can remote monitoring vehicle, this vehicle comprises wireless monitor controller (100) and engine controller (200),Described wireless monitor controller (100) can with remote service center (300) wireless connections, this remote service center (300) can change the licensing status of described wireless monitor controller (100), so that this wireless monitor controller (100) can'"'"'t be by the checking of described engine controller (200) in uncommitted situation;

  • Described engine controller (200) links to each other with described wireless monitor controller (100), be used for verifying first before starting engine whether described wireless monitor controller (100) authorizes through remote service center (300), and in the situation that checking is passed through, just allow starting engineWherein,Described wireless monitor controller (100) generates random number, utilize encryption key and the cryptographic algorithm of storing in the described wireless monitor controller (100) that described random number is encrypted, obtain encrypted ones, and described random number and encrypted ones are sent to engine controller (200);

    AndDescribed engine controller (200) receives described random number and encrypted ones, and utilize encryption key and the cryptographic algorithm of storing in the described engine controller (200) that the random number that receives is encrypted, obtain another encrypted ones, this another encrypted ones and the encrypted ones that receives are compared, if both are identical, show that then described wireless monitor controller (100) authorizes through remote service center (300), otherwise show that described wireless monitor controller (100) authorizes without remote service center (300).
