A typical ultrasonic sensor has a major lobe that extends beyond 45 degrees. Because the wide beam of sensor’s main lobe, which is used for straightforward distance measurement, low angular resolution, conventional methods such as incidence angle and linear measurements cannot accurately determine azimuthal angle. Determining whether one or more objects are present in single also challenging. I...

Tire slip angle is a vital parameter in tire/vehicle dynamics and control. This paper proposes an accurate estimation method by the fusion of intelligent tire technology machine-learning techniques. The equipped MEMS accelerometers attached to its inner liner. First, we describe system along with implemented testing apparatus. Second, experimental results under different loading velocity condit...

Sideslip angle is an important variable for understanding and monitoring vehicle dynamics but it lacks inexpensive method direct measurement. Therefore, typically estimated from inertial other proprioceptive sensors onboard using filtering methods the family of Kalman Filter. As a novel alternative, this work proposes modelling problem directly as graphical model (factor graph), which can then ...

Array receiver structures for tracking the motion of targets using only passive signals have been developed. The "bearings only" problem has been investigated in a state-variable context. The effects of target motion on the temporal structure of signals, e. g., Doppler effects, have been incorporated, and lead to a receiver structure that is similar to a phase-locked loop coupled to a split-bea...
