Embodiment Construction
[0045] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0046] The structure of the automobile keyless system of the present invention, as figure 1 As shown, it includes a connected induction remote controller 1 and a main control mechanism 2. The main control mechanism 2 has an MCU module 5 inside, and the main control mechanism 2 is also connected to the executive mechanism 3 and the original vehicle circuit 4. The connection between the induction remote controller 1 and the main control mechanism 2 is realized through wireless communication, and the main transmitted signals are remote control signals and induction signals, and the remote control signals include remote control unlocking, remote locking, remote car search, and remote trunk; The induction signal is the induction door lock and the induction door lock. Both the remote control signal and the induction signal can realize opening and ...

The invention discloses an automobile keyless system, comprising an inno tech used for inducing the low frequency induction signals sent by a master control mechanism and transmitting the remote control operation command signals, the master control mechanism used for responding to the signals of the inno tech and carrying out corresponding process and operation and an executing mechanism used for executing an operation command sent by the master control mechanism to drive corresponding electric devices to move, wherein the inno tech is connected with the master control mechanism, the master control mechanism is also connected with the executing mechanism and a primary circuit inside the automobile. Regarding the communication encryption method for the automobile keyless system of the invention, the study process of the inno tech and the master control mechanism is carried out at first, and then the communication process of the inno tech and the master control mechanism is carried out. The automobile keyless system and the communication encryption method thereof solve the problems of redundancy in opening and closing door locks of the present automobiles and potential safety hazard of communication in the system.
Description
technical field [0001] The invention belongs to the technical field of automobile electronics, and relates to an automobile switch door lock device, in particular to an automobile keyless system, and also relates to a communication encryption method of the system. Background technique [0002] At present, car door locks generally use high-frequency wireless communication with button remote control, which is inconvenient (keys and buttons are required) and unsafe (forgetting to lock the door when leaving the car, and the remote control command is captured or cracked). The encryption method is mainly through the traditional encryption mode and the relatively new KEELOQ rolling code encryption algorithm. For the KEELOQ rolling code encryption algorithm, first of all, its security is based on the factory key and seed code SEED, and the factory key is composed of the factory serial number and manufacturer code. , Seed code generation (in security mode), the manufacturer code is f...
