The invention provides a vehicle anti-theft system and a vehicle anti-theft method. The vehicle anti-theft system comprises a master node arranged on a vehicle and at least two slave nodes in communication connection with the master node. The master node is configured to generate an unlock request in response to an unlock signal from the PEPS system. Each slave node is configured to generate a challenge message after receiving an unlocking request from the master node, and execute a vehicle unlocking security check after receiving a response message corresponding to the challenge message from the master node. And under the condition that the result of the vehicle unlocking safety verification performed at each slave node is passed, the master node sends a function activation permission message to each slave node, so that the function of each slave node is unlocked. And under the condition that the vehicle unlocking safety verification result of at least one slave node is not passed, the master node sends a message for forbidding function activation to each slave node, so that function unlocking of all the slave nodes is forbidden.
本发明提供了一种车辆防盗系统和车辆防盗方法。该车辆防盗系统包括设置在车辆上的主节点和与主节点通信连接的至少两个从节点。主节点构造成:响应于来自于PEPS系统的解锁信号生成解锁请求。各个从节点构造成:在接收到来自于主节点的解锁请求之后生成挑战消息,以及在从主节点接收到对应于所述挑战消息的应答消息之后执行车辆解锁安全性校验。在每个从节点处进行的车辆解锁安全性校验的结果均为通过的情况下,主节点向各个从节点发送允许功能激活消息,以便各个从节点的功能解锁。在至少一个从节点处的车辆解锁安全性校验的结果为不通过的情况下,主节点向各个从节点发送禁止功能激活的消息,从而禁止所有从节点的功能解锁。
