The invention relates to a vehicle-mounted SerDes chip, a data transmission system comprising the same and a vehicle. The vehicle-mounted SerDes chip is provided with a function safety controller module which is used for forwarding a function safety state to the outside, and further comprises a function module which is connected with a data source in the vehicle-mounted SerDes chip, processes first data from the data source and outputs the first data as second data; the read-back module is connected with the output end of the function module and reads back the second data to the vehicle-mounted SerDes chip; and the comparison module is used for receiving the first data and the second data, and sending an error signal to the function safety controller module when the first data and the second data are judged to be inconsistent, so that the function safety controller module forwards the error signal to the main control chip. By comparing the data before and after the output of the functional module of the chip, whether the signal output by the chip to the use end is accurate is detected, so that the vehicle-mounted safety is ensured.

    本发明涉及车载SerDes芯片、包括其的数据传输系统及车辆。所述车载SerDes芯片具有功能安全控制器模块,用于向外部转发功能安全状态,并且,进一步具有:功能模块,连接车载SerDes芯片内部的数据源并将来自数据源的第一数据处理和输出为第二数据;回读模块,连接功能模块的输出端并将第二数据回读至车载SerDes芯片;比较模块,用于接收第一数据、第二数据,在判定第一数据与第二数据不一致时,向功能安全控制器模块发送错误信号,以供功能安全控制器模块转发至主控芯片。本发明通过对芯片的功能模块输出前后的数据进行比较,检测芯片对使用端输出的信号是否准确,从而保证车载的安全性。
