Method and system for unlocking and starting vehicle based on voice system outside vehicle

Abstract

The invention discloses a method and a system for unlocking and starting a vehicle based on an out-of-vehicle voice system, and relates to the field of intelligent networked vehicles. The system comprises a cloud platform used for generating and verifying a random secret key for vehicle identity authentication; intelligent mobile equipment which communicates with the cloud platform through a communication network and requests to generate a visible random secret key; a pickup which is arranged in a key of the PE door handle and serves as a wake-up source of a voice system outside the automobile; an out-of-vehicle voice system which is used for processing a random secret key input by out-of-vehicle voice, and an offline module of the out-of-vehicle voice system transmits the random secret key to the T-Box vehicle-mounted intelligent terminal; the T-Box vehicle-mounted intelligent terminal transmits the received random secret key to the cloud platform for verification; the vehicle body control module receives a signal transmitted by the T-Box through a CAN signal and is used for giving vehicle unlocking and ignition authority.

Description

technical field [0001] The invention is used in the field of intelligent networked vehicles, and in particular relates to a takeover method for keyless entry and starting of a vehicle based on an external voice system. Background technique [0002] With the increasing development of intelligent networked vehicles, people now have higher and higher requirements for "convenience, intelligence, and safety" in cars. Providing a different entry method from traditional car physical keys can make the car more convenient and high-tech Smart sense. How to enter and start a vehicle without carrying a mechanical key has become a research direction of more and more people. At present, the mainstream solutions for replacing physical keys include Bluetooth keys, face keys and card keys, but there are still the following shortcomings: 1. You need to carry a mobile phone or card key. If it is lost, the vehicle may be stolen; 2. Biometric keys such as faces have high hardware costs, and th...

AI Technical Summary

Problems solved by technology

However, the technology of this patent has the following problems: First, the mobile terminal and the unlocker are required to have visible light signal receiving and conversion hardware equipment, which requires high technical requirements and hardware costs for visible light signals; Key storage and sent directly to the unlocker through the mobile terminal, there is a greater risk of leakage

However, the stability of the connection between the built-in Bluetooth of the mobile phone and the Bluetooth of the car is not high. When the mobile phone is missing or forgotten, it cannot effectively solve the scene of keyless entry into the vehicle.

[0005] Application No. 202010725356.7 Name A method for starting a vehicle without a key provides a way to start the vehicle by presetting an asymmetric public key to the body controller to request a random factor from the cloud for matching before the vehicle leaves the factory; the existing problems are The steps of requesting random factor input authentication are too cumbersome, and the technical solution described in this patent is too small for use scenarios. It still needs to carry mobile terminals or mechanical keys, and it does not completely solve the smart and convenient scenarios that replace traditional keys.
