Video-based roll angle estimation for two-wheeled vehicles

2011 IEEE Intelligent Vehicles Symposium (IV), 2011
Video-based driver assistance systems are a key component for intelligent vehicles today. Applications for lane detection, traffic sign recognition, and collision avoidance have been successfully deployed in cars and trucks. State-of-the art algorithms rely on machine learning and therefore depend on invariance conditions, e.g.

Neural Roll Angle Estimation in a Model Predictive Control System

2019 IEEE Intelligent Transportation Systems Conference (ITSC), 2019
This article deals with the integration of a neural state estimator into a control environment. A pre-trained recurrent neural roll angle estimator is analyzed in a closed loop environment of a model predictive control. The roll estimator consists of long short-term memory cells and predicts the angle based on the lateral acceleration, the steering ...

On Navigation Systems for Motorcycles: The Influence and Estimation of Roll Angle

Journal of Navigation, 2005
Vehicle navigation systems use various sensors and the global positioning system (GPS) to locate a vehicle. This location is then matched to a map database to provide navigation information. Between GPS updates, the vehicle's heading angle and forward speed are used to “dead reckon” its position.

Estimation of the Roll Angle in a Spinning Guided Munition Shell

2006 IEEE/ION Position, Location, And Navigation Symposium, 2006
A projectile in flight follows a trajectory defined by an interaction of gravity, aerodynamics, and mechanical forces due to spin, shape and possible steering fins. The projectile’s flight phases can be described in terms of a pre-launch phase, launch phase, and ballistic phase.

Roll angle estimation of a spinning object: Experimental setup and preliminary results

2015 27th International Conference on Microelectronics (ICM), 2015
In this paper, a low-complexity concept is presented to estimate the roll angle of a spinning object. The circuitry is based on a radio frequency (RF) power detector in combination with a linearly polarized antenna for signal reception. Due to the utilization of the power detector, the requirement on the sampling rate of the mandatory analog-to-digital

Roll angle estimation for motorcycles: Comparing video and inertial sensor approaches

2012 IEEE Intelligent Vehicles Symposium, 2012
Advanced Rider Assistance Systems (ARAS) for powered two-wheelers improve driving behaviour and safety. Further developments of intelligent vehicles will also include video-based systems, which are successfully deployed in cars. Porting such modules to motorcycles, the camera pose has to be taken into account, as e. g.

Robust bank angle estimation for rolling stability control on electric vehicle

2010 11th IEEE International Workshop on Advanced Motion Control (AMC), 2010
In this paper, vehicle state variables and bank angle estimation for rolling stability control (RSC) is proposed using one accelerometer and two gyro sensors, instead of using inertial navigation system (INS) or global positioning system (GPS). We proposed a novel robust RSC for in-wheel motor electric vehicle (IMEV) using differential torque by right ...

Fault detection in roll angle estimation for two-wheeled vehicles

IFAC Proceedings Volumes, 2012
The knowledge of the lean angle represents a fundamental information to design a control system for the out-of-plane dynamics of 2-wheel vehicles. Recent papers has tackled successfully the problem of lean angle estimation by the use of inertial sensors.

Real Time Roll Angle Estimation for Fast Spinning Projectiles

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2018
This paper presents a roll angle estimation algorithm that can be employed in all spinning projectiles regardless of their spin rate. The proposed algorithm uses GNSS velocity information in combination with 2 axis rate gyroscope measurements. An important contribution of the paper is that the algorithm is designed considering the GNSS measurements has
