in addition to increment of the vehicle sprung mass, the main physical effects of addition of cng tank to the vehicle are the longitudinal and height displacement of center of gravity, which have the most influences on the handling, braking, roll stability and spin stability of the vehicle. increment of cng tank mass to the sprung mass of the vehicle increases the vehicle under-steer gradient, ...

Vehicle trajectories contain rich information on microscopic phenomena such as car following and lane changing. Despite many efforts to retrieve reliable trajectories from video images, previous approaches do not give high enough quality of trajectories that can be used in microscopic analysis. We introduce a new vehicle tracking approach based on a model-based 3-D vehicle detection and descrip...

Visual angle car following models assume fixed values (thresholds) for the angular velocity (∆Ө/∆t) over which the driver of the following vehicle is affected by the leading vehicle. This paper explains the advantages and limitations of such models and provides possible solutions for these limitations. Sensitivity analysis has been carried out for these purposes as a part of this paper. It was ...

Vehicle automation is used to increase traffic throughput and road safety. Automated vehicles should be highly versatile navigate on both highways urban roads. To do so, fully automated autonomous often adopt motion planners ensure collision-free comfortable trajectories. In contrast, in cooperative driving, feedback control achieve string-stable vehicle-following at very short inter-vehicle di...

In this paper, an improved distributed model predictive control (IDMPC) method for the platoon consisting of electric vehicles is put forward. And motion performed in two dimensions, which contains longitudinal and lateral motion. Firstly, a built based on car-following single following vehicle. Then, IDMPC strategy designed with consideration multiple objectives. The symmetrical weight matrice...
