This paper presents an improved electric vehicle (EV) dynamic model by considering the actual environmental conditions for EV powertrain components testing. The environmental conditions considered include the road gradient, road surface roughness, weather conditions, and wind speed. In comparison to the simplified vehicle dynamics model, the proposed enhanced model aims to simulate the vehicle dynamics...
This article deals with the design and modeling of PID regulators with two degrees of freedom for the thermal phase of the hybrid vehicle. It shows how to regulate the speed of a vehicle using a PID control with two degrees of freedom with a set point weighting. Two main objectives of this controller are tracking set points and rejecting load disturbances at the same time. A number of control algorithms...
The purpose of this research is the modeling and Linear Control of Quad copter through pitch, roll, yaw and thrust command Interface. This research starts with derivation of nonlinear mathematical model of quad copter dynamics that consists of 6 degree of freedom(DOF) motions. The non-linear model is then linearized around equilibrium point and then 3DOF kinematics is extracted in order to design...
In this paper, the series-parallel drivetrain architecture present in Hybrid Electric Vehicles is studied and modeled in detail using Matlab/Simulink. The system is composed of two permanent magnet synchronous machines in addition to the internal combustion engine all mechanically combined using a power split device. The novelty of this model is to use exclusively basic Simulink blocks resulting in...
The paper presents a concept, development and comparison of selected control algorithms used in distributed control system of a three wheeled vehicle. First simulations are carried out, then the selected algorithms are tested on a real vehicle. The article includes the description of the mathematical model of the tricycle: kinematics, dynamics, motor drives, central control system, communication network...
Fossil fuel depletion risk forecasting and growing environmental concerns are strong impetus for developing higher efficient transportation system nowadays. Hybridization is considered as one of the most efficient short and mid-term solutions. In particular, series hydraulic hybrid configuration provides a further advantage when it provides more degree of freedom of engine control. However, low energy...
For future mobility intended to decrease energy consumption by smaller and lighter body and also by applying low RRC (Road Resistance Coefficient) tires, there is a possibility that maneuverability and stability of such a vehicle will become reduced than current conventional vehicles. To solve this problem, a benchmark study is announced by ‘Committee of vehicle control and modeling research’ of JSAE...
This paper describes a PSIM simulator for the analytical approach of the HEV (Hybrid Electric Vehicle) power train operation. For this research, a series-parallel type HEV (SPHEV) are chosen to apply the Forward-Facing approach simulation method. As the traction power of the series-parallel type HEV can be supplied from both of the ICE (Internal Combustion Engine) and the traction motor, the planetary...
Electric Power Steering (EPS) systems have many merits over traditional hydraulic power steering systems in fuel economy, variable assist capabilities and favorable road feeling by virtue of adjustment assist characteristic with adopting assist motor in replacement of hydraulic pump. This paper aims at modeling the mechanical parts, the assist motor and electronic control unit by bond graph technique...
In order to be an effective tool for driver evaluation and education, driving simulators need to be better designed to reduce simulator sickness. In this paper, we expose platform design, description and the modeling aspects of a 2 DOF low cost motion platform allowing the restitution of the longitudinal and yaw movements. To enhance the drive immersion in the virtual world, a haptic feedback steering...
In this brief, a new methodology for the identification of engine maps from static data is presented. In order to enhance the flexibility of the model and exploit prior knowledge on the boundary conditions of the maps, a basis function neural network with a large number of neurons is used. To ensure smoothness of the estimated map as well as guarantee reliable extrapolation properties, the weights...
To accomplish the demand of minimum fuel consumption and good power performance for continuously variable transmission (CVT) car. Aiming at the whole vehicle model including the engine, the clutch and the CVT, the dynamics mathematical model of CVT system is established according to different stages of clutch engaging, that the dynamic integrated simulation model is developed. A parameter self-adjusting...
This paper reports the modeling, identification and experimental validation of a marine propeller dynamic model. In fact, the existing models well reproduce propeller thrust and torque, but only at low dynamics. In practice, the rate of change of propeller rotational speed is then limited by the thruster controllers to avoid unmodeled phenomena. Otherwise important tracking error can occur during...
