The invention relates to the technical field of vehicle manufacturing, in particular to a circuit board structure of a vehicle-mounted steering system, the vehicle-mounted steering system and a vehicle. In the circuit board structure, an electronic element on a first driving circuit board and an electronic element on a second driving circuit board are backup elements for each other; the first driving circuit board is in communication connection with the control circuit board through a first flexible circuit board, and the control circuit board is in communication connection with the second driving circuit board through a second flexible circuit board; the first driving circuit board performs information transmission with the second driving circuit board through the control circuit board; after the first flexible circuit board and the second flexible circuit board are bent, the circuit board structure is arranged in a multi-layer circuit board mode. The electronic components which are mutually backup components are respectively arranged on the two circuit boards, so that under the condition that a certain electronic component is damaged, the backup component can be started, the vehicle can operate normally, the safety of the vehicle is ensured, and the user experience is improved.
本申请涉及车辆制造技术领域,特别涉及一种车载转向系统的电路板结构、车载转向系统和车辆;在电路板结构中,第一驱动电路板上的电子元件以及第二驱动电路板上的电子元件互为备份元件;第一驱动电路板与控制电路板通过第一柔性电路板通信连接,控制电路板与第二驱动电路板通过第二柔性电路板通信连接;第一驱动电路板通过控制电路板与第二驱动电路板进行信息传输;在第一柔性电路板以及第二柔性电路板进行弯折后,电路板结构呈多层电路板设置;通过将互为备份元件的电子元件分别设置在两个电路板上,进而在某一电子元件受损的情况下,能够启动备份元件,车辆可以正常运行,保证车辆安全,提高用户体验。
