    摘要： A method is provided for estimating vehicle velocity for a vehicle using a single-antenna global positioning system (GPS). An absolute speed and a course angle of the vehicle is measured using the single-antenna GPS. The yaw rates of the vehicle are measured independently of the GPS. An integrated yaw rate of the vehicle is calculated as a function of the measured yaw rates over a period of time. A yaw angle is determined as a function of a reference yaw angle and the integrated yaw rate. Aside slip angle is calculated as a function of the estimated yaw angle and the course angle provided by the GPS. The vehicle velocity is determined as a function of the absolute speed and the side slip angle. The vehicle velocity is provided to a vehicle dynamic control application.

    摘要： A diagnostic method for improving the reliability, accuracy, efficiency and/or robustness of a vehicle dynamic control system (VDCS) by providing analytical redundancy for one or more sensor readings. Sensor readings such as wheel speed, yaw rate, lateral acceleration, longitudinal acceleration and steering angle are oftentimes related to one another. Thus, the diagnostic method may use these dynamic relationships to detect faults in the sensor readings without having to add additional redundant hardware or use complex circular logic structures, which can increase the cost and impose processing burdens on the VDCS. In an exemplary embodiment, the diagnostic method checks for faulty sensor readings through a process of analytical redundancy that includes intra- and inter-parameter evaluations having linear and forward dependencies.
