The invention discloses a signal transmission circuit and a vehicle, and the signal transmission circuit comprises a first power supply which is connected to the output end of a first controller and the first end of a level conversion module, and is used for providing a first voltage of a first high-level signal to the level conversion module when the output end of the first controller outputs the first high-level signal; the second end of the level conversion module is connected to the input end of the second controller, and the level conversion module is used for converting the first voltage of the first high-level signal into a first low-level signal or converting the second voltage of the second low-level signal into a second high-level signal and inputting the second high-level signal into the input end of the second controller. The high-level signal and the low-level signal which are externally input are converted through the level conversion module, it is ensured that the high-level signal and the low-level signal which are input into the second controller are safe and stable, and it is avoided that the second controller identifies signals mistakenly or is damaged due to external fluctuation.
本发明公开了一种信号传输电路以及车辆,信号传输电路包括:第一电源,连接于第一控制器的输出端以及电平转换模块的第一端,用于当第一控制器的输出端输出第一高电平信号时,提供第一高电平信号的第一电压至电平转换模块;电平转换模块,电平转换模块的第二端连接于第二控制器的输入端,用于将第一高电平信号的第一电压转换为第一低电平信号,或者将第二低电平信号的第二电压转换为第二高电平信号后,并输入至第二控制器的输入端。通过电平转换模块将外部输入的高电平信号、低电平信号进行转化,确保输入第二控制器的高电平信号、低电平信号是安全且稳定的,避免外部波动导致第二控制器识别信号出错或者出现损坏。
