Abstract
Vehicle safety remains a topic of major interest, and diverse assistance systems are implemented that focus primarily on analyzing the immediate vicinity of the car and the driver’s control inputs. In this paper, by contrast, we emphasize understanding the driver’s control performance via obtaining valuable data and relevant characteristics. To acquire the data, we employed an in-house-designed, laboratory-built vehicle driving simulator. This simulator exploits the Unreal Engine 4 framework to deliver a high level of realism. The fact that the actual designing and associated processes were materialized through our own efforts has brought advantages such as simplified data acquisition, possibility of creating custom scenarios, and modification of the virtual elements according to our specific needs. We also developed an application to analyze the measured data from the perspective of control theory, establishing a set of parameters that provided the basis for an early version of a driver performance index indicator.
Highlights
In all state-of-the-art technologies, safety embodies a most important parameter
In order to create a safe test environment, vehicle driving simulators find use as an effective, simulation-based alternative comprising multiple scenarios that may be difficult to execute in real life
We opted for developing an in-house vehicle driving simulator because commercially available devices did not allow us to create custom scenarios and to modify the software to suit our research needs
Summary
Scientists and engineers are attempting to combine adequate safety precautions, considering all relevant aspects, while making every effort to maintain a reasonable price for the final product. These facts obviously apply to the automotive industry and the development of new technologies that are or will be implemented in modern cars [1]. Many tests are conducted to evaluate vehicles or drivers (for example, the moose test); such assessment, tends to be rather costly and, most significantly, potentially dangerous for the test subjects (drivers). In order to create a safe test environment, vehicle driving simulators find use as an effective, simulation-based alternative comprising multiple scenarios that may be difficult to execute in real life. The advantages of a simulator are presented in [2,3,4]
