Obviously, The described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

请参阅图1，图1为本发明第一实施例提供的机动车控制方法的实现流程示意图，本实施例从执行主体为无钥匙进入及启动系统PEPS控制器的角度进行描述，本发明实施例中提供的机动车控制方法包括：Please refer to Fig. 1. Fig. 1 is a schematic diagram of the implementation flow of the motor vehicle control method provided by the first embodiment of the present invention. The motor vehicle control methods provided in include:

S101、无钥匙进入及启动系统PEPS控制器获取智能钥匙的身份信息并保存；S101. The PEPS controller of the keyless entry and start system obtains and saves the identity information of the smart key;

S102、按照预置的秘钥生成规则生成第一秘钥以及与第一秘钥匹配的第二秘钥，并将第二秘钥发送给智能钥匙；S102. Generate a first secret key and a second secret key matching the first secret key according to a preset secret key generation rule, and send the second secret key to the smart key;

步骤S101及S102是智能钥匙的学习过程，当PEPS控制系统进入智能钥匙的学习状态后，用户将智能钥匙放置在机动车IMMO(发动机防盗锁止系统)线圈处，该PEPS控制器就会与智能钥匙之间进行低频通讯。PEPS控制器会获取并保存智能钥匙的身份信息等重要信息，生成并保存第一秘钥以及与第一秘钥匹配的第二秘钥，并将该第二秘钥写入智能钥匙相应的存储器中，可以理解的，此处的第一秘钥和第二秘钥可以是相同的秘钥。这样，在该学习过程结束后，PEPS控制器与智能秘钥之间不管是进行高频通讯还是低频通讯，都会涉及到密钥数据，从而保障了汽车的安全。Steps S101 and S102 are the learning process of the smart key. When the PEPS control system enters the learning state of the smart key, the user places the smart key at the coil of the IMMO (immobilizer system) of the motor vehicle, and the PEPS controller will communicate with the smart key. Low frequency communication between keys. The PEPS controller will obtain and save important information such as the identity information of the smart key, generate and save the first secret key and the second secret key matching the first secret key, and write the second secret key into the corresponding memory of the smart key , it can be understood that the first secret key and the second secret key here may be the same secret key. In this way, after the learning process is over, no matter whether high-frequency communication or low-frequency communication is performed between the PEPS controller and the smart key, the key data will be involved, thereby ensuring the safety of the car.

PEPS控制器生成第一秘钥以及与第一秘钥匹配的第二秘钥，具体包括：调用第一预置次数的C语言函数，生成第一预置位数的随机数，将该第一预置位数的随机数作为第一秘钥；调用第二预置次数的C语言函数，生成第二预置位数的随机数，将第二预置位数的随机数作为第二秘钥。The PEPS controller generates the first secret key and the second secret key matching the first secret key, which specifically includes: calling the C language function for the first preset number of times, generating a random number with the first preset number of digits, and using the first The random number of the preset number of digits is used as the first secret key; the C language function of the second preset number of times is called to generate the random number of the second preset number of digits, and the random number of the second preset number of digits is used as the second secret key .

在本实施例中，密钥不是个固定的值，要是随机值，因此通过调用C语言的函数来生成秘钥，在C语言中，函数srand()就是给rand()提供种子的，如果srand每次输入的参数是一样的，那么每次运行产生的随机数也是一样的；如果srand每次输入的参数不一样，那么每次运行产生的随机数也不一样。选择定时器的毫秒值作为函数srand()的参数，这样每次调用rand()，所生成的随机数就是变化的。产生随机数的函数的C代码如下所示：In this embodiment, the key is not a fixed value, but a random value, so the secret key is generated by calling a function in C language. In C language, the function srand() provides seeds for rand(). If srand If the input parameters are the same each time, the random numbers generated by each run are also the same; if the parameters input by srand are different each time, then the random numbers generated by each run are also different. The millisecond value of the timer is selected as the parameter of the function srand(), so that each time rand() is called, the generated random number changes. The C code for the function that generates random numbers is as follows:

unsigned int Create_random(void)unsigned int Create_random(void)

{{

unsigned int uiRandSeed＝Get_mSecond_value()；//采集定时器的毫秒值unsigned int uiRandSeed＝Get_mSecond_value();//collect the millisecond value of the timer

srand(uiRandSeed)；srand(uiRandSeed);

return(rand())；return(rand());

}}

该代码每次运行，能产生一个16位的随机数。若需要生成128位数的随机数作为第一秘钥，则需要连续调用8次上述函数即可得到。Each time the code runs, it generates a 16-bit random number. If you need to generate a 128-digit random number as the first secret key, you need to call the above function 8 times in a row to get it.

当PEPS控制系统进入智能钥匙的学习状态后，PEPS控制器和智能钥匙之间通过低频(LF)方式进行通讯，频率在120K-140K之间，有效通讯距离在10CM以内。通过相关的通讯协议，可以直接通过明码的方式将第二密钥写入到智能钥匙相应的存储器中，也可以通过Hash编码的方式，对第二秘钥进行加密，以非明码的方式将第二密钥写入到智能钥匙相应的存储器中，采用加密的方式安全性更高，操作也更复杂。When the PEPS control system enters the learning state of the smart key, the PEPS controller and the smart key communicate through low frequency (LF), the frequency is between 120K-140K, and the effective communication distance is within 10CM. Through the relevant communication protocol, the second key can be directly written into the corresponding memory of the smart key in a clear way, or the second secret key can be encrypted by Hash coding, and the second key can be written in a non-clear way. The second key is written into the corresponding memory of the smart key, and the encryption method is more secure and the operation is more complicated.

S103、当接收到智能钥匙发送的配对信息及控制指令时，分别验证配对信息中包含的身份信息和第二秘钥与保存的身份信息和第一秘钥是否匹配；S103. When receiving the pairing information and the control instruction sent by the smart key, respectively verify whether the identity information and the second secret key included in the pairing information match the saved identity information and the first secret key;

步骤S103及S104是智能钥匙通过PEPS控制器控制机动车的过程。Steps S103 and S104 are the process in which the smart key controls the motor vehicle through the PEPS controller.

配对信息中包含该智能钥匙的身份信息及第二秘钥。分别将配对信息中包含的身份信息与在步骤S101中获取并保存的身份信息进行匹配，将配对信息中包含的第二秘钥与步骤S102中生成的第一秘钥进行匹配。The pairing information includes the identity information of the smart key and the second secret key. The identity information included in the pairing information is matched with the identity information acquired and saved in step S101, and the second secret key included in the pairing information is matched with the first secret key generated in step S102.

S104、若配对信息中包含的身份信息与保存的身份信息相匹配，且第二秘钥与第一秘钥相匹配，则控制打开机动车中控制指令指向的对应部件。S104. If the identity information included in the pairing information matches the saved identity information, and the second secret key matches the first secret key, control to open the corresponding component in the motor vehicle to which the control command points.

其中，打开机动车中控制指令指向的对应部件，可以但不限于包括：打开全部车门的车锁；打开控制指令指向的目标车门的车锁；打开后备箱的车锁；启动汽车的引擎。Wherein, unlocking the corresponding parts pointed to by the control command in the motor vehicle may include, but is not limited to: unlocking the locks of all doors; unlocking the locks of the target doors pointed to by the control command; unlocking the lock of the trunk; starting the engine of the car.
