Entry and starting system and method for entry and starting verification
An entry system includes a transponder unit and a transmission unit which is arranged in an object. The transmission unit is designed to transmit a request to the transponder unit, and the transponder unit includes a motion sensor which is designed to detect a movement of the transponder unit and to generate motion information. The transponder unit is designed to transmit, in a first operating state, to the transmission unit, in response to the request, a reply containing the motion information, wherein the transmission unit is designed to decide on the basis of the motion information whether to activate the object.
1. An entry system comprising:
a transponder unit and
a transmission unit which is arranged in an object, wherein
the transmission unit is designed to transmit a request to the transponder unit;
the transponder unit comprises a motion sensor which is designed to detect a movement of the transponder unit and to generate motion information;
the transponder unit is designed to transmit, in a first operating state, to the transmission unit, in response to the request, a reply containing the motion information, and wherein
the transmission unit is designed to decide on the basis of the motion information whether to activate the object,
wherein the transponder unit is also designed to transmit to the transmission unit a notification that the transponder unit will transition into a second operating state within a predefined second time interval after transmission of the notification, the second operating state being a state in which one or more components of the transponder unit are disabled.
2. The entry system as claimed in claim 1 , in which the transmission unit is also designed to activate the object if the transmission unit recognizes from the motion information that the transponder unit has been moved within a predefined first time interval prior to transmission of the request.
3. The entry system as claimed in claim 1 , in which the transmission unit is also designed to decide on the basis of at least one specified state transition criterion, after receiving the notification, whether to transmit to the transponder unit an instruction that causes the transponder unit to remain in the first operating state within and beyond the predefined second time interval after transmission of the notification.
4. The entry system as claimed in claim 1 , in which activating the object comprises at least one of the following activities:
unlocking the object;
locking the object;
giving the object clearance to start; and
switching on the object.
5. The entry system as claimed in claim 1 , in which the transmission unit and the transponder unit are additionally designed to transfer the request, the reply, the notification and the instruction in signed or encrypted form.
6. The entry system as claimed in claim 1 , in which the transmission unit is also designed to decide on the basis of the motion information and at least one specified activation criterion whether to activate the object.
7. The entry system as claimed in claim 6 , in which the at least one specified activation criterion is selected from a group consisting of:
a locking state of the object;
an operating state of the object; and
a position of the transponder unit relative to the object.
8. The entry system as claimed in claim 1 , in which the transponder unit is arranged in one of the following portable devices:
a vehicle key;
a smartphone;
a tablet; and
a laptop.
9. A method which comprises:
transmitting a request from a transmission unit to a transponder unit, wherein the transmission unit is arranged in an object;
detecting movements of the transponder unit by means of a motion sensor and generating motion information;
transmitting from the transponder unit to the transmission unit a reply containing the motion information; and
the transmission unit deciding on the basis of the motion information whether to activate the object, wherein
the transmission of the reply takes place in a first operating state of the transponder unit and in response to the request,
wherein the transponder unit is also designed to transmit to the transmission unit a notification that the transponder unit will transition into a second operating state within a predefined second time interval after transmission of the notification, the second operating state being a state in which one or more components of the transponder unit are disabled.
10. A vehicle comprising an entry system, wherein the vehicle comprises a transmission unit which is arranged in the vehicle, and a transponder unit, which is arranged in a portable device, wherein
the transmission unit is designed to transmit a request to the transponder unit;
the transponder unit comprises a motion sensor which is designed to detect a movement of the transponder unit and to generate motion information;
the transponder unit is designed to transmit, in a first operating state, to the transmission unit, in response to the request, a reply containing the motion information, and wherein
the transmission unit is designed to decide on the basis of the motion information whether to activate the vehicle,
wherein the transponder unit is also designed to transmit to the transmission unit a notification that the transponder unit will transition into a second operating state within a predefined second time interval after transmission of the notification, the second operating state being a state in which one or more components of the transponder unit are disabled.
