if so, an anti-theft instruction is sent out to control the vehicle window system, the engine locking system and the door lock system to enter a locking state.
3. An automobile keyless starting apparatus characterized by comprising: memory, processor and a vehicle keyless start program stored on the memory and executable on the processor, which when executed by the processor implements the steps of the vehicle keyless start method according to any of claims 1 to 2.
4. A storage medium having a car keyless start program stored thereon, which when executed by a processor, implements the steps of the car keyless start method according to any one of claims 1 to 2.
5. A keyless starting device for a vehicle, comprising: the device comprises an acquisition module and a starting module;
the acquisition module is used for acquiring low-frequency key information and digital key information from the intelligent key;
the starting module is used for judging whether to start the target vehicle according to the low-frequency key information and the digital key information;
the starting module is further used for continuously detecting position information of the digital key, encrypting the position information of the digital key and then sending the encrypted position information of the digital key to the bus, acquiring position information of the low-frequency key when an activation signal for opening the door of the target vehicle is received, judging whether the intelligent key is located in a preset area of the target vehicle according to the position information of the low-frequency key, acquiring the position information of the digital key from the bus if the intelligent key is judged not to be located in the preset area of the target vehicle, judging whether the intelligent key is located in the preset area of the target vehicle according to the position information of the digital key, and opening the door of the target vehicle if the intelligent key is located in the preset area of the target vehicle;
the starting module is further used for continuously detecting the position information of the digital key, encrypting the position information of the digital key and then sending the encrypted position information of the digital key to the bus, acquiring the position information of the low-frequency key when receiving an activation signal for starting a target vehicle, judging whether the intelligent key is positioned on the target vehicle according to the position information of the low-frequency key, if the intelligent key is judged not to be positioned on the target vehicle, acquiring the position information of the digital key from the bus, judging whether the intelligent key is positioned on the target vehicle according to the position information of the digital key, and if so, starting the target vehicle;
when a request instruction of the intelligent key is received, a verification request is sent to the intelligent key, the verification request comprises a random code automatically generated by the keyless entry device through a random number generator, a calculation result fed back by the intelligent key is received, the received calculation result is matched with a calculation result obtained by self calculation, and whether a vehicle is started or not is judged according to the matching result, wherein the calculation result fed back by the intelligent key is a result obtained by confirming a safety algorithm corresponding to a keyless entry mode according to the verification request when the intelligent key receives the random code, and calculating the random code through the safety algorithm.
