Problems solved by technology

When the OFF gear is in the standby state for a long time, the static power consumption of the whole vehicle will be large, resulting in a high risk of vehicle power feeding
[0005] In summary, both of the above two methods require the whole vehicle to work in a low power consumption state, which still has the problem of high power consumption, and the identification steps are relatively cumbersome.

Abstract

The invention provides a vehicle owner identity recognition system and method. The system comprises an NFC card; a first NFC controller which comprises an MCU awakening circuit and an MCU, the awakening circuit is used for awakening the MCU when the NFC card is close to the first NFC controller, so that the first NFC controller performs near field communication with the NFC card, the first NFC controller acquires vehicle owner information in the NFC card and verifies the vehicle owner information, and if the vehicle owner information in the NFC card passes the verification, the first NFC controller performs authentication communication with the vehicle body controller; and a vehicle body controller which is in communication connection with the first NFC controller and is used for controlling the vehicle door to be unlocked. According to the system, the power consumption is reduced, and the step of identity recognition is simplified.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a vehicle owner identification system, method and vehicle. Background technique [0002] When performing identification of the vehicle owner, it is first necessary to wake up the whole vehicle or wake up the NFC controller, and then the identification of the vehicle owner can be performed. [0003] When the vehicle is in low-power sleep, the user presses the door handle micro switch to generate a low-level signal, and the battery manager is awakened when it detects the low-level signal, and then the battery manager wakes up the vehicle through the CAN signal. After waking up the vehicle, the owner needs to swipe the NFC card to realize the identity authentication. Unlocking the vehicle is a cumbersome operation; some models have the NFC sensing area arranged at the exterior rearview mirror, which will cause pressing the micro switch, swiping the exterior rearview mirror a...
