汽车虚拟仪表的指针设计与实现

Design and Realization of Car Virtual Instrument

针对汽车虚拟仪表指针运动过程中的指示准确度、响应时间和平滑性问题,将传统汽车仪表机械指针运动机制与显示器帧频率相结合,设计一种虚拟指针运动控制方案。CANoe硬件在环仿真实验结果表明:该方案不仅满足指针指示的准确度和响应时间要求,而且指针运动过程中无拖影、跳变等现象。

Aiming at the indication accuracy, response time and smoothness in the movement process of car virtual instrument pointer, a virtual pointer motion control scheme was presented by combining the mechanical pointer movement mechanism of traditional automobile instrument with the display frame frequency. Through CANoe hardware-in-the-loop simulation experiment, the experimental shows that this scheme not only meets the requirements of pointer accuracy and response time, but also has no phenomenon of smear and jump during the movement of pointer.
