Abstract

The invention provides a key-free vehicle entry system and an automobile and is applicable to the field of automobile electron. The key-free vehicle entry system comprises one or a plurality of wireless identification cards, a wireless base station which is in wireless communication with the wireless identification cards and adjustable in emission power, a main controller in connected communication with the wireless base station and a control circuit connected with the main controller, and the wireless base station, the main controller and the control circuit are arranged in a vehicle. The key-free vehicle entry system emits wireless identification signals through the wireless base station with the adjustable emission power, exchanges data with the wireless identification (ID) card, achieves wireless identification of the vehicle, adjusts effective range of wireless ID card detection by adjusting the emission power, and achieves identification of the plurality of wireless ID cards.

Description

technical field [0001] The invention belongs to the field of automotive electronics, in particular to a vehicle keyless entry system and an automobile. Background technique [0002] The development of technology has promoted the renewal of automobiles. The vehicle entry system has changed from the original mechanical key to the remote control system. With the wide application of RFID technology and the demand of the automobile market, the remote entry system has been replaced by the keyless entry system. [0003] The car keyless entry system (Passive Keyless Enter, PKE) is not a traditional key, but a smart key or smart card, using RFID wireless radio frequency technology and vehicle identification code identification system, applying miniaturized, low-power radio frequency antenna, integrating remote control system and The keyless system follows the traditional vehicle circuit protection, and automatically opens the door after identifying the vehicle's identity to achieve k...
