为了更好的提高虚拟驾驶模拟系统人机交互的灵活性及稳定性,主要研究了基于转向阻力矩的方向盘交互方法。转动方向盘后,底层硬件驱动对方向盘转角信号进行实时采集,并将转角信号传送给虚拟驾驶模拟系统;根据实际方向盘转向阻力矩计算出对应虚拟汽车转向阻力矩;根据虚拟汽车转向阻力矩计算汽车转弯角速度;计算汽车转弯后的位置信息和朝向信息,完成虚拟汽车转向。为了验证该方法的有效性,设计并实现了一款半实物的虚拟驾驶模拟系统,并且应用了该方向盘交互方法。实验证明,该方法是可行有效的。采用该方法设计的驾驶模拟系统已经在实际中应用,运行稳定。
In order to improve the flexibility and stability of human-computer interaction in virtual driving simulation system, the steering wheel interaction method based on steering resistance moment is mainly studied. After turning the steering wheel, the underlying hardware driver collects the steering wheel angle signal in real time and transmits the steering angle signal to the virtual driving simulation system; calculates the corresponding steering resistance torque of the virtual car according to the actual steering wheel steering resistance torque; calculates the car turning curve according to the steering resistance torque of the virtual car Angular velocity; calculation of the car after turning the location information and orientation information, to complete the virtual car steering. In order to verify the effectiveness of the method, a semi-physical virtual driving simulation system is designed and implemented, and the steering wheel interaction method is applied. Experiments show that this method is feasible and effective. The driving simulation system designed by this method has been applied in practice and runs steadily.
