The invention provides a signal monitoring system applied to a vehicle key chain, and the system comprises a processor and a memory; the memory stores an executable instruction of the processor, and when the instruction is executed by the processor, the following steps are realized: monitoring a signal in a preset frequency range; decoding the received signal in the preset frequency range; determining a signal characteristic of the received signal; in response to the received signal being unable to be decoded, notifying the vehicle computing system to display an alert to the driver based on the signal feature. The invention further discloses a corresponding vehicle and method. According to the scheme provided by the invention, hardware does not need to be transformed, and different countermeasures can be taken according to the signal characteristics and sources of the interference signals, so that the production cost is reduced, and the use satisfaction degree of a driver is improved.

    本发明提供了一种应用于车辆钥匙扣的信号监测系统,包括处理器和存储器,存储器存储有处理器可执行指令,指令被处理器执行时实现以下步骤:监测预设频率范围内的信号;对接收到的预设频率范围内的信号进行解码;确定所接收到的信号的信号特征;响应于所接收到的信号无法被解码,通知车辆计算系统基于信号特征向驾驶者显示告警。本发明还公开了相应的车辆和方法。本发明提出的方案无需在硬件方面进行改造,并且可以根据干扰信号的信号特性及其来源采取区别应对措施,从而降低了生产成本并且提升了驾驶者使用满意度。
