The invention provides a vehicle-mounted intelligent cockpit sharing display method and system. The method comprises the steps that S1, a central control terminal draws an image to be output to a virtual display screen; S2, the image to sequentially pass through a display middle layer and a kernel driving layer, and then image data is writted into a preset shared memory area; S3, the updated information of the image data is transmitted to an dashboard; S4, the dashboard reads the image data from the shared memory area after receiving the information; and S5, the image data is displayed on thedashboard. Information interaction, including image transmission through memory sharing, among multiple devices is completed through chip internal memory sharing, multiple device functions are achieved only through one physical host, and the product is more flexible, safer, more stable and more reliable. The equipment host is single, so that the automobile body wire harness is decreased progressively in multiples, the product cost is greatly reduced due to the reduction of research, development, manufacturing, packaging and transportation links, and the unit price advantage of the whole product is more obvious.

    本发明提供一种车载智能座舱共享显示方法及系统,包括步骤:S1、中控端将要输出的图像绘制到虚拟显示屏上;S2、将所述图像依次通过显示中间层和内核驱动层后将图像数据写入预设的共享内存区域中;S3、将所述图像数据已更新的信息发送至仪表端;S4、所述仪表端接收所述信息后从所述共享内存区域中读取所述图像数据;S5、将图像数据显示在所述仪表端上。通过芯片内部内存共享完成多设备间的信息交互,包括图像通过内存共享传输,仅需一个物理主机实现多个设备功能,产品更加灵活、安全、稳定、可靠。设备主机单一,使得车身线束成倍递减,研发、制造,包装、运输、各环节的缩减使产品成本上得到较大的降低,产品整机单价优势更明显。
