In this paper, the problem of comfort and handling improvements of a ground vehicle is treated through the joint control of the suspension and braking systems. Two H∞ gain-scheduled controllers are synthesized to achieve, attitude and yaw performances according to the driving situation, observed through of a simple vehicle monitor. The proposed strategy tackles the nonlinear tire braking force ...

In this article, we evaluate the performance of an iterative registration algorithm for position estimation of Unmanned Ground Vehicles (UGVs) operating in unstructured environments. Field data obtained from trials on UGVs traversing undulating outdoor terrain is used to quantify the performance of the algorithm in producing continual position estimates. These estimates are then compared with t...

Ground leveling by bulldozer blade should be automatically controlled since the operation is an exhausting work for the bulldozer operator. In this paper, fuzzy control is used for the blade operation in the ground leveling. A series of tests using model bulldozing vehicle are carried out to check the effect of membership functions in the fuzzy control and the vehicle speed. Moreover some tests...

This paper uses the Bekker model for land locomotion analysis to compare ground vehicle vehicles with different running gear configurations. The Bekker model is inherently phenomenological in nature and requires empirical data to both calibrate and validate the methodology for realistic soil/terrain conditions. This formalism consists of two fundamental equations. The first uses the Coulomb-Moh...

We propose a circular path and linear momentum method for the seismic response analysis of vehicles. This method considers the momentum induced by earthquake excitation and applies the concept of centripetal force acting laterally on the vehicle in addition to longitudinal forces. This method is valid for vehicles at rest as well as those moving at a range of speeds. The vertical responses are ...

An excellent navigation, guidance, and control (NGC) system had a high impact on trajectory tracking the following scenarios. Both scenarios will include heading, tangent, velocity parameters in computation. However, design problem is not new issue unmanned surface vehicle (USV) autonomous ground vehivle (AGV) due to this constraint faced by many researchers since early these autonomy developme...

This paper presents the power management strategy for a parallel hybrid electric vehicle (PHEV). The vehicle is powered by dual energy sources consisting of internal combustion engine (IC engine) as the peak power source and the electric battery as the secondary energy source. The operational principle of the power management strategy and the possible power flow patterns are described. Based on...

Most studies of pedestrian injuries focus on reducing traumatic injuries due to the primary impact between the vehicle and the pedestrian. However, based on the Pedestrian Crash Data Study (PCDS), some researchers concluded that one of the leading causes of head injury for pedestrian crashes can be attributed to the secondary impact, defined as the impact of the pedestrian with the ground after...
