This paper presents results of a parametric study performed on an automotive air-conditioning (AAC) system of a passenger car. The goals are to assess the effects of varying the volumetric flow rate of supply air, number of occupants, vehicle speed, and the fractional ventilation air intake (XOA), on the dry-bulb temperature and specific humidity of the air inside the passenger’s cabin, and on ...

It is well known that the vehicle interior noise comfort is one of the main target which may attract customers for purchasing a vehicle. Eventually, the amount of discomfort depends on magnitude, frequency, direction and, as well as, on the duration in vibration exposition inside the cabin. The comfort of the driving strongly influences the driving performances. Generally, the acoustic noise ex...

A noisy environment dominated by low frequency noise can often be improved through the use of active noise control. This situation arises naturally in propeller aircraft where the propellers induce periodic low frequency noise inside the cabin. The cabin noise is typically rather high, and the passenger flight comfort could be improved considerably if this level were significantly reduced. This...

It has been suggested that the risk of rupture of intracranial aneurysms may be fostered by climatic drops in barometric pressure, as also occurs to passengers subjected to the air pressure settings inside aircraft cabins. We present two cases of flight-related aneurysmal SAH followed by intracerebral rebleeding in the cabin (case 1) and carotid dissection after landing (case 2). Management and...

The paper describes the design and test of a prototype active noise controller for a semienclosed cabin inside a turbo-prop aircraft. Here, the eight active noise control loudspeakers and sixteen microphones are mounted at the cabin walls and ceiling. For the development process, an acoustical mock-up is built to reproduce the acoustic situation inside the aircraft on the ground. The acoustic r...

As interest in autonomous driving increases, efforts are being made to meet requirements for the high-level automation of vehicles. In this context, functionality inside vehicle cabin plays a key role ensuring safe and pleasant journey driver passenger alike. At same time, recent advances field artificial intelligence (AI) have enabled whole range new applications assistance systems solve autom...

This paper shows the effect of adding vibrations in a car cabin during driving simulation on driver perception. Actually, current dynamic driving simulators induce the simulator sickness and it still difficult for the driver to project himself in the virtual reality due to a lack of perception. To know the effect of vibrations on a subject, the effect of the whole body vibration must be defined...

UNLABELLED Quick information on airborne infectious disease transmission in airliner cabins is essential to reduce the risk of infection of passengers and crew members. This investigation proposed a one-dimensional analytical model that can predict the longitudinal transmission of airborne contaminants or disease viruses inside an airliner cabin. The model considered both diffusive and convecti...

Vision for intelligent vehicles is a growing area of research [6] for many practical reasons including the relatively inexpensive nature of camera sensing units and even more the non-contact and non-intrusive manner of observation. The latter is of critical importance when observing occupants inside the vehicle cockpit because no sensing unit should impede the primary task of driving. Conventio...
