The invention relates to a vehicle-mounted SerDes chip, a vehicle-mounted data transmission system comprising the same and a vehicle. The vehicle-mounted SerDes chip is provided with an input interface and an output interface, wherein the input interface is used for being connected with external equipment and receiving error information of the external equipment; the function safety controller is connected with the input interface, so that the error information can be input into the function safety controller as an external function safety mechanism; and the output interface is connected with the function safety controller, and the output interface is used for being connected with a main control chip so as to send the error information of the external equipment to the main control chip. According to the invention, the error information of the external electronic and electrical system can be transmitted to the main control chip by using the internal safety controller of the vehicle-mounted SerDes chip, so that the error information can be responded and processed in time, and the system architecture is simplified.
本发明涉及车载SerDes芯片、包括其的车载数据传输系统和车辆。所述车载SerDes芯片具有:输入接口,所述输入接口用于连接外部设备以及接收所述外部设备的错误信息;功能安全控制器,所述功能安全控制器连接所述输入接口,从而所述错误信息能够作为外部功能安全机制被输入至所述功能安全控制器;以及输出接口,所述输出接口连接所述功能安全控制器,并且所述输出接口用于连接主控芯片以向所述主控芯片发送所述外部设备的所述错误信息。本发明能够利用车载SerDes芯片的内部安全控制器向主控芯片传输外部的电子电气系统的错误信息,实现对该错误信息作及时响应处理,简化了系统架构。
