Embodiment Construction
[0023] In one embodiment, the interaction between the key and the base station is realized through the direct interaction between the key and the NXP chip (the signal processing process of the wireless radio frequency module and the modem unit is ignored here). The internal coprocessor of the NXP chip also includes Hitag2 / Hitag3, 11, 12, 13 and other algorithm logics, so that the NXP chip can be set as a common anti-theft chip compatible with various car models; the NXP chip has two memories, EEPROM and Erom, and the internal EEPROM is used for It is used to store anti-theft data, cooperate with the internal algorithm coprocessor of the chip to realize anti-theft function, internal Erom stores anti-theft user program, anti-theft user program includes anti-theft basic program and anti-theft application program, anti-theft basic program controls NXP chip to enter configuration mode or run anti-theft application program, In the configuration mode, the NXP chip can be configured wi...

The invention provides a software configuration method and device for a universal automobile key, and belongs to the technical field of automobile electronics. Obtaining first identity authentication information according to the first instruction, and sending the first identity authentication information to the initialization equipment; receiving a second instruction; second identity authentication information is obtained according to the second instruction, the second identity authentication information is sent to the initialization equipment, so that the initialization equipment matches the first identity authentication information with target identity authentication information corresponding to the second identity authentication information, and if matching succeeds, the initialization equipment configures software to the automobile key. The method can be used for realizing software configuration of various vehicle types, anti-theft software and remote control software are both stored in an erasable memory, when the vehicle type controlled by the vehicle key needs to be replaced, the existing anti-theft software and remote control software are erased, and then the software corresponding to the target vehicle type is configured in the vehicle key by utilizing the method, so that the vehicle type controlled by the vehicle key can be replaced. Hardware does not need to be replaced, and resource occupation is reduced.
Description
technical field [0001] The invention belongs to the technical field of automobile electronics, and more specifically relates to a wireless configuration method of a universal automobile key. Background technique [0002] With the increase of car ownership year by year, the number of damaged and lost car keys is also increasing year by year. The differences in anti-theft systems of different vehicles and the continuous update of car anti-theft technology make car keys various and have different functions. Car keys as consumables Bring difficulties to the automobile repair and maintenance market. [0003] At present, a typical car key is mainly composed of an anti-theft chip and a wireless remote control. The anti-theft chip usually has a unique chip identification number and an authentication key. When the ignition switch is turned on or the car is started, the anti-theft chip responds to the engine challenge data. If the response data is correct , the car can start. Differ...
