Models created in a digital world are put through a simulation analysis test and installation evaluation through auto simulation and a 3-D digital design process to review possible problems in advance. This process greatly optimizes engineering design and minimizes development times.
Body structure design
The body structure acts much like the skeleton in a human body, providing the basic framework for driving parts like the engine and chassis, as well as various convenience systems. We consider all of the qualities required of a car, such as strength, crash resistance, aerodynamics, quietness, fuel efficiency and space, when designing a car that is safe, comfortable, fast and economical.
A vehicle‘s exterior and interior are designed with a focus on providing a pleasant, comfortable and safe environment for passengers. A new technology called adaptive headlamps involves low-beam bulbs swiveling left and right in response to the steering wheel so that they illuminate where the driver is looking rather than straight ahead. Additionally, the lamps move up and down in consideration of the number of passengers and vehicle yaw.
NVH (noise, vibration, harshness) analysis
To control vibration and noise levels encountered during driving, we analyze the causes of vibration and characteristics of how vibrations are relayed to vehicle occupants. Reduction of these factors takes place using computer simulation two to three years before an actual car is made.
After several engineering design proposals are examined, an optimal solution is selected and a prototype car is produced. To minimize noise and vibration during driving, we identify their points of origin and then try to eliminate the root causes. This process is conducted with the help of computerized technologies up to three years before the first prototype vehicles are built. Once all conceivable sources of noise and vibration have been isolated, we can then begin manufacturing the first prototypes.
A virtual car model is created to obtain quantitative data on the load that is transferred from the road surface to the car body while driving. Based on the load predictions on the body and suspension, we conduct detailed modeling and durability analysis which enable us to pinpoint weak areas and execute durability assessment studies.
Package layout refers to the series of engineering works required to efficiently form and arrange key elements of a vehicle, taking various conditions into consideration. In sum, it deals with realizing concepts from the entire development process, from the design concept stage to mass production, into a technically concrete format. The process is aimed at maximizing customer comfort and convenience by achieving optimal space, field of visibility, comfort, maneuverability, storage, assembly, and maintenance convenience.
