Description :
CAVA is a suite of products that can be bought together (CAVA All) or individually:
• CAVA OVA (Overall Vehicle Architecture): at the start of the design process – at the Vehicle Concept phase – usually no detailed geometry for the vehicle is present. The definitive vehicle parameters, such as dimensions, seat positions, etc., are still subject to alteration. In order to create quickly and visually the various (legal) requirements applicable to any current design, CAVA OVA offers a wide range of possibilities.
• CAVA Vision: there are a wide range of requirements for vehicle construction with which manufacturers have to comply which relate to the driver's direct and indirect vision, the latter via the rear view mirror. In CAVA VISION these tasks are covered by a series of different CAVA features.
• CAVA Mirror: Subset of the CAVA Vision module covering the rear view mirror requirements.
• CAVA Safety: the direct safety of passengers and pedestrians plays an increasingly major role in the development of new vehicles. It is also approved by some "crash tests" on the real vehicle, based on regulations which are still relatively new. It is important for the designer to identify as early as possible within the CAD System those areas which have to be checked by means of crash tests. With regard to the protection of pedestrians, these include the bonnet and the windscreen, and certain areas in the interior of the vehicle in the case of head impact. The size and position on these areas depends on the vehicle parameters but also on the vehicle geometry in particular.
• CAVA Manikin: within the sphere of ergonomics, SAE Standards specify a two-dimensional test dummy, for use in determining the various passenger positions. The dummy can be positioned according to the many different options relating to the geometric guidelines or specifications for the angle of the body and relevant parameters. Using the contours of the head position and the eye view points and ellipses, all the relevant SAE parameters, such as e.g. headroom or legroom, can be verified. Positioning is also possible across or against the direction of travel.
• CAVA Wiper: the geometry of the windshield wipers is not as such subject to legislation, however the area to be wiped must fulfil certain standards. With CAVA Wiper the user can simulate the geometry of the wipers and so determine the wiped area on the windscreen. Used together with the Field of View feature in CAVA Vision, it is possible to check the percentage of wiped area within the field of view.
