The invention provides a drive-by-wire system based on an off-chip multi-core chip, a communication method and a vehicle. The drive-by-wire system comprises a first control chip, a second control chip and a first driving chip, wherein the first control chip and the second control chip are arranged in a redundant mode, and the first control chip and the second control chip are in communication connection with the first driving chip. The first control chip is in communication connection with the second control chip through a first pin and a second pin. The first pin is used for sending a communication state detection signal of the first control chip and the first driving chip; and the second pin is used for receiving a reset enable signal of the first control chip. Through the line control system, the reliability of communication among multiple chips in the system can be ensured, and the safety in the field of automotive electronics is improved.

    本申请提供了一种基于片外多核芯片的线控系统、通信方法和车辆。其中的线控系统包括:冗余设置的第一控制芯片和第二控制芯片、第一驱动芯片,所述第一控制芯片、所述第二控制芯片分别与所述第一驱动芯片通信连接;所述第一控制芯片分别通过第一引脚和第二引脚和所述第二控制芯片通信连接;所述第一引脚,用于发送所述第一控制芯片与所述第一驱动芯片通信状态检测信号;所述第二引脚,用于接收所述第一控制芯片的复位使能信号。通过该线控系统可保证系统中多颗芯片间通信的可靠性,提高汽车电子领域的安全性。
