Advanced automotive display measurements: Selected challenges and solutions

Today's trend in automotive displays is toward more, larger, better, and flexible panels. The requirements for cars differ largely from consumer displays: Automotive displays have unique requirements in terms of optical performance, longevity in harsh environment, and production of 100,000s per year per model. Consumer electronics displays, however, set the pace and premium automotive panels have to follow in short time because of customer expectations despite long development cycles. Advanced procedures and measurements have to be applied like lifetime and ambient light. In order to reduce the effort in specifying and evaluating car displays in terms of optical performance, the German Flat Panel Forum has set common requirements for automotive validation. As standard measurement procedures are often less suitable for automotive evaluation, dedicated methods were developed like Black Mura, gamma and visual assessment of anti‐glare surfaces. Standardization reduces the effort along the automotive display value chain. People in future autonomous cars will spend more time watching displays than today, which must then be of highest optical performance. Design visions trend to present information – and not displays – to driver and passengers, which includes seamless displays and smart surfaces. A simple integration of flat displays into dashboards is no longer state‐of‐the‐art.     

The influence of company identity on the perception of vehicle sounds

In order to determine how the interior of a car should sound, automotive manufacturers often rely on obtaining data from individual evaluations of vehicle sounds. Company identity could play a role in these appraisals, particularly when individuals are comparing cars from opposite ends of the performance spectrum. This research addressed the question: does company identity influence the evaluation of automotive sounds belonging to cars of a similar performance level and from the same market segment? Participants listened to car sounds from two competing manufacturers, together with control sounds. Before listening to each sound, participants were presented with the correct company identity for that sound, the incorrect identity or were given no information about the identity of the sound. The results showed that company identity did not influence appraisals of high performance cars belonging to different manufacturers. These results have positive implications for methodologies employed to capture the perceptions of individuals. STATEMENT OF RELEVANCE: A challenge in automotive design is to set appropriate targets for vehicle sounds, relying on understanding subjective reactions of individuals to such sounds. This paper assesses the role of company identity in influencing these subjective reactions and will guide sound evaluation studies, in which the manufacturer is often apparent.

Advanced methods for safe visualization on automotive displays

Camera Monitor Systems (CMSs), for example, for backup cameras or mirror replacements, become increasingly important and already cover safety aspects such as guaranteed latency and no frame freeze. Today's approaches deal only with supervision of the digital interface, LCD backlight, and power supply. This paper introduces methods for advanced safety monitoring of panel electronics and optical display output that aim to enable future CMS based automotive use cases. Our methods are based on correlation of physical measurements with predicted values derived from a corresponding display model. This model was made via calibration measurements and many test patterns. Correlation of the monitoring results with predicted values corresponds to the probability that the RGB data are shown as intended. This implies that an overlying system, an Automotive Safety Integrity Level (ASIL) Prepared Video Safety System (APVSS), ensures that only safety verified RGB data are provided to the panel electronics. In case of failures, our methods enable a safe system state, for example, by deactivating the panel. An additional challenge is to allow graceful degradations, a safe but slightly degraded image may provide a better customer experience compared with no information. We successfully verified our approach by a fully functional prototype and extensive evaluation towards “light‐to‐light” (camera to display output) supervision.     

Analysis of the bonding process and materials optimization for mitigating the Yellow Border defect on optically bonded automotive display panels

The Optical Bonding (OB) technology has become a critical aspect of the performance of displays, and an essential requisite of their supply chain. This paper presents the development and the implementation of a technological solution to the OB of automotive instrument panel displays. The goal is to select and develop the adequate materials and bonding techniques that can meet the rigorous performance, quality, cost and productivity of OB displays for the automotive industry. The implementation of a display wet-OB production line is firstly presented. The process is then optimised by selecting the adequate silicone based OB materials that can eliminate defects such as Yellow Border, YB (a type of MURA defect), meeting the application requirements at reduced cycle time.

Vehicle velocity estimation using nonlinear observers

Nonlinear observers for estimation of lateral and longitudinal velocity of automotive vehicles are proposed. The observers are based on a sensor suite that is standard in many new cars, consisting of acceleration and yaw rate measurements in addition to wheel speed and steering angle measurements. Two approaches are considered: first, a modular approach where the estimated longitudinal velocity is used as input to the observer for lateral velocity, and second, a combined approach where all states are estimated in the same observer. Both approaches use a tire-road friction model, which is assumed to be known. It is also assumed that the road is flat. Stability of the observers is proven in the form of input-to-state stability of the observer error dynamics, under a structural assumption on the friction model. The assumption on the friction model is discussed in detail, and the observers are validated on experimental data from cars.

A Factor Analysis of Consumer Expectations for Autonomous Cars

This study explores consumers’ expectations for autonomous cars in Korea, which will soon be available. We applied exploratory and confirmatory factor analyses to derive consumer expectations using responses from 1,506 potential autonomous car consumers. Then, we carried out a structural equation analysis to identify relationships among expectations, attitude, and behavioral intention. Seven consumer expectations were identified; of these, convenience, safety, ethics, licensing, and monetary cost were found to have a direct effect on attitude, whereas convenience, safety, and monetary cost were found to have a direct effect on intention. In addition, we demonstrate that attitude has a significant effect on intention. Autonomous cars are driving innovation in the automotive industry, transportation systems, and consumer experience. By analyzing the main factors that affect consumers’ purchasing intentions prior to the release of autonomous cars, this study provides guidance for fields preparing for the launch of autonomous cars.     

Advanced optical methods for safe image reproduction on automotive displays

Modern cars are equipped with camera monitor systems (CMSs), such as a backup camera or side-mirror replacement. These systems are expected to perform optimally and achieve high safety levels (ASIL). Currently, only digital data are supervised in CMSs and safety mechanisms for such systems are individually derived on a case-by-case basis which is not effective. This study proposes generic optical supervision for displays of automotive CMS. This paper introduces “light-to-light” (camera to display output) protection for both in-car CMS and remote operator monitors used in autonomous car fleet operation centers. The first method is based on photodiodes attached to the display to optically supervise, for instance, the speedometer of vehicles. By combining intensities of photodiodes with calibration data, we can compare the measured speed with the value from CAN (Controller Area Network) data. The second method that entails capturing the display content using a camera enables top safety levels for both in-car displays and remote operator monitors. This safeguarding was successfully verified by conventional image processing and artificial intelligence (AI)-based analysis methods. Our results demonstrate that AI methods allow a substantial reduction in the wireless transmission bandwidth from a car to a remote operator compared with conventional image processing.
