The invention discloses an intelligent cabin instrument safety display method based on an SOC hard isolation technology, and relates to the technical field of automobile intelligent cabins. According to the invention, the instrument function is realized by monitoring the vehicle information through the two independent domains, and the backup function of the 2D instrument and the 3D instrument function are respectively realized through the Safety and the AP2. When the AP2 has an unknown fault and cannot normally output the display content, switching to a backup 2D instrument interface under the Safety so as to continuously provide the display of the important information of the vehicle and achieve the purpose of safe display of the information of the vehicle; when the 3D instrument application of the AP2 processes important vehicle information display, whether display content is complete and safe or not is confirmed by comparing a CRC value, calculated by a read-back display output controller, of a corresponding display area with a CRC value calculated by software when picture content is generated, and corresponding warning is given by Safety when the display content is abnormal, so that the purpose of safe instrument display is achieved.

    本发明公开了一种基于SOC硬隔离技术的智能座舱仪表安全显示方法,涉及汽车智能座舱技术领域。本发明通过2个独立域都监听车辆信息来实现仪表功能,通过Safety、AP2分别实现2D仪表的备份功能、3D仪表功能。当AP2出现未知故障而无法正常输出显示内容时切换到Safety下的备份2D仪表界面,以此来继续提供车辆重要信息的显示,达到车辆信息显示安全的目的;当AP2的3D仪表应用在处理重要车辆信息显示的时候,通过回读显示输出控制器计算的对应显示区域的CRC值,与图片内容产生时通过软件计算的CRC值对比来确认显示内容是否完整安全,异常时由Safety给出相应警告,以此达到仪表显示安全目的。
