摘　　要：介绍了一种具有运动-力解耦功能的多维车轮力传感器。基于车轮力传感器的特殊安装与实用环境的测量误差,在常规轮力传感器力-力维间解耦与测量的基础上,引入运动测量技术与校正方法,提出了一种联合的解耦方法,能够对运动场下传感器测量的旋转耦合误差和惯性耦合误差进行补偿,同时还兼顾初值误差校准,进一步提高了车轮力的测量精度和稳定性,即实现运动-力解耦。This work presents a new designed wheel force transducer which can decouple between the motion and force. Since the wheel force transducer is specially-designed and installed on the spinning wheel of a vehicle, the rotation and inertial couplings cause errors into the force measurement. With the introduced the motion measurement technique such as a MEMs unit, these errors can be eliminated with the combined algorithms including the rotation decoupling, inertial decoupling, and the initial error calibration, so the precision of force measurement can be improved for the transducer.
