Daylight changes from moment to moment, in brightness, colour and direction under changing bright daylight, in-vehicle displays can become unreadable due to washout or glare, causing driver distraction or masking safety critical information. With an increasing number of vehicle systems being controlled through a centralised display, the legibility of automotive displays under ambient lighting conditions has become an important consideration for engineers in terms of perceived quality, safety and driver distraction. Due to the dynamic nature of the sky, testing under natural daylight would not give the control required for meaningful measurements. Therefore, the challenge for the automotive industry is to standardise the simulation of illumination for performing assessments and to make the process controlled, repeatable and comparable to real daylight situations. The main objective of this project is to propose a method for recreating a daylight-comparable lighting environment to enable the evaluation of vehicle interiors under high ambient lighting conditions and to propose best-practice for illumination used in legibility evaluation for design and validation activities. This is achieved with a measurement and simulation approach, to evaluate current procedures and determine the gap between real world, simulation and lab-based assessments, and bring them closer to the real-world. There are two main outputs from this project; a comparative simulation study which verifies digital tools for use by JLR in display design and evaluation activities, and the recommendation to align physical and digital methods to move evaluations earlier in the new product development process. A concept has been included to enable controlled measurements as part of physical evaluations, as are the critical factors required for a repeatable physical environment for physical testing as the basis of continuous improvement of digital simulations.
