MCU+GDC双系统的汽车虚拟仪表设计
|
摘要
以瑞萨MCU+东芝GDC作为双处理器,提出了车载虚拟仪表的设计方案和系统构成,成功研制出了量产产品。商用车实验测试与路试结果表明,该方案提出的电源管理满足供电要求,采集的CAN数据与硬线传感器数据准确度高,图像处理过程中无跳变、残影等现象。
Using Renesas MCU and Toshiba GDC as dual processor,the design scheme of the vehicle virtual instrument and the system structure are put forward,and the mass production products are successfully developed.The experiment and road tests results of commercial vehicles show that the power management proposed by the scheme satisfies the power supply requirements,and the acquired CAN data and sensor data have high accuracy,and there is no jumping or residual image in the image processing process.
