Problems solved by technology

This solution greatly increases power consumption, especially when the vehicle is not started, and will greatly accelerate the consumption of battery power in the vehicle
Existing CID identification systems are difficult to reduce power consumption while overcoming noise interference from the instrument panel
[0007] Second, traditional single RSSI solutions are difficult to accurately determine the location of the smart key in the vehicle

Embodiment Construction

[0026] figure 1 A schematic diagram of a vehicle 100 is shown, wherein a first antenna 101 and a second antenna 102 are arranged in the vehicle 100 . The second antenna 102 is arranged at the front of the vehicle 100, closer to the dashboard 103 of the vehicle; while the first antenna 101 is arranged at the rear of the vehicle 100, ie farther away from the dashboard 103 of the vehicle.

[0027] The first antenna 101 and the second antenna 102 send out a first signal and a second signal respectively. The second antenna 102 is closer to the dashboard of the vehicle and may receive greater electronic interference; while the first antenna 101 is farther away from the dashboard of the vehicle and may receive less electronic interference. In an embodiment according to the present invention, the power of the second antenna 102 is increased so that the power of the second antenna 102 is greater than the power of the first antenna 101, so that the signal emitted by the second antenna ...

Abstract

The present invention relates to an identity code recognition system for keyless entry and start of a vehicle, comprising: a first antenna arranged in a first area of ​​the vehicle and configured to transmit a first signal; a second antenna arranged in a first area of ​​the vehicle In the second area, and configured to transmit a second signal; the smart key is configured to interact with the first antenna and the second antenna to complete the matching verification of the smart key and the vehicle; wherein, the second area is more secure than the first area An electronic jamming device that is close to the vehicle and that transmits more power from the second antenna than the first antenna. The invention also includes an identification code identification method using the system.

Description

technical field [0001] The present invention relates to a system for identifying a coded identity (CID) in polling identification, and a method for identifying a CID in polling identification. [0002] The system and method are particularly used in PEPS systems (Passive Entry and Passive Start, ie keyless entry and start systems) for motor vehicles (such as cars, cars, trucks, etc.). And, the CID refers to the identity code of the vehicle, and corresponds to the smart key used in the PEPS system corresponding to the vehicle with the identity code. Background technique [0003] The PEPS system of the car is one of the most representative solutions in the wireless entry application of the vehicle. It uses radio frequency technology and an identity code identification system to automatically open and close the door lock through the smart key carried by the car owner. The driver can open the door and start the vehicle without pressing the remote button on the smart key or inser...
