Vehicle Cabin Noise Simulation due to High-frequencies Stimulation
In this paper, the acoustic environment in a vehicle cabin under the influence of highfrequencies aerodynamic sources has been studied. Some panels on the windshield, the roof, the doors, the front pillars, and the floor of a vehicle simulated as input source of noise when the car is moving at high speed, i.e. 112 km/h. The status of vehicle cabin in each of these modes has been studied and com...
متن کاملParameters Design and Economy Study of an Electric Vehicle with Powertrain Systems in Front and Rear Axle
To achieve higher economy of the original driving scheme with single motor and settled gear ratio, new configurations with different powertrain systems in front and rear axle were designed. Firstly, according to the power and torque required by a micro electric vehicle (mEV) in various drive cycles, the parameters of a small and high power motor were determined. Secondly, for schemeⅠwith dual m...
متن کاملLong distance moving vehicle detection using rear lamp at night
This paper proposes a vehicle detection system for identifying the moving vehicles at night which is far distance away by locating their rear-lights in the road. Many advanced driver-assistance systems (ADAS), such as collision mitigation, automatic cruise control (ACC) and automatic headlamp dimming were proposed by many researchers for driver assistance. We present a novel image processing sy...
متن کاملStability of Three-Wheeled Vehicles with and without Control System
In this study, stability control of a three-wheeled vehicle with two wheels on the front axle, a three-wheeled vehicle with two wheels on the rear axle, and a standard four-wheeled vehicle are compared. For vehicle dynamics control systems, the direct yaw moment control is considered as a suitable way of controlling the lateral motion of a vehicle during a severe driving maneuver. In accorda...
متن کاملModeling Driver Response to Lead Vehicle Decelerating
This paper presents a driver performance map of braking and steering in response to three driving scenarios that lead to rear-end crashes. This map encompasses low risk, conflict, near-crash, and crash imminent driving states that correspond to advisory warning, crash imminent warning, and crash mitigation functionalities for intelligent vehicle rear-end crash countermeasures. Specifically, thi...
