Computational steering allows researchers to monitor and manage long running, resource intensive applications at runtime. Limited research has addressed high performance computational steering. High performance in computational steering is necessary for three reasons. First, a computational steering system must act intelligently at runtime in order to minimize its perturbation of the target app...

According to the independence, accuracy and controllability of the driving/braking torque of the distributed drive electric vehicle, a control strategy of differential drive assisted steering was designed. Firstly, the assisted curve under different speed and steering wheel torque was developed and the differential torques were distributed to the right and left front wheels. Then the steering r...

Recently, automatic steering systems for emergency obstacle avoidance have been studied extensively. The control input of such active steering control systems can be classified into the steering angle and the steering torque input. The steering torque based control provides some degree of freedom for drivers to control the vehicle motion, thus it has potential for development as steering assist...

this research presents a guidance-assistance system for agricultural swing machines. the new automatic steering system controls the vehicle based upon the position of the traces of the previous operation carried out on the field. for each image the trace of the tilled soil by seed drill is placed either on the center line, or on either side of the line. for traces coinciding with images' c...

[Abstract] An automated E/H steering controller is essential for autonomous off-road equipment. This paper presents a methodology for designing the E/H steering controller through a combination of testing and simulation. The steering kinematic model provides the steering linkage gain between the hydraulic actuator and the front wheel. The model makes it possible to close the steering control lo...

There are a variety of factors affecting steering performance on off-road vehicles, including vehicle dynamics and soil stiffness. It is essential to understand the steering dynamics for designing a reasonable electrohydraulic (E/H) steering control system for wheel-type tractor. A computer-controlled E/H steering simulator, consisting of a steering actuator and a steering load simulator, is an...

To design an automatic steering controller with high performance for autonomous vehicle, it is necessary to have a precise model of the lateral dynamics with respect to the steering command input. This paper presents an empirical modeling of the steering system for an autonomous vehicle. The steering system here is represented by three individual transfer function models: a steering wheel actua...

This paper aims to develop a driver steering model that can capture driver’s key steering mechanisms from a control engineering point of view. Analyses with Double Lane Change (DLC) vehicle test data suggest that, instead of following the traditional concept of trajectory planning, drivers use target points located along the centerline of the lane they are changing to as references for control....

Interactive Computational Steering is the online, interactive allocation and adjustment of system resources and application parameters. Causal consistency is an important feature of interactive steering of distributed computations, as it is often required to maintain the correctness of the computation. However, due to the asynchronous nature of distributed computations, it is difficult to coord...
