In the frame of SAHE, Hybrid and Electric Automotive Show, celebrated in Valladolid from the 22nd to the 24th of April, Cidaut has presented its last innovations related to sustainable mobility and intelligent transport.
At Cidaut’s booth, it was possible to see and touch two of the prototypes development in the last research and development projects carried out by the technological center. The first one was a crash test prototype that had been tested according to Regulation 94 homologation, in the frontal part of the vehicle the consequences of the crash were still visible. The rest of the vehicle has been repaired in order to shortly make an additional lateral pole crash test. Inside the vehicle, in the driving position, a crash test dummy was seated in order to make this testing tool familiar to the visitors. Most of the youngest assistants to the show were surprised and happy to see and touch the dummy while very few were surprised or scared.
The second prototype was a functional extra-light and safe urban electric vehicle. The interior of this prototype was monitored with a simple webcam and thanks to the application of artificial vision solutions, the vehicle was able to determine the position of the occupants, the direction of their glance, the number of flickers and yawns, and the alertness level of the driver. This solution will be applied to avoid unattended driving in automated driving scenarios, but also in standard driving conditions. The vehicle was open for the visitors to come in and test the performance of the monitoring systems. Again the youngest visitors were the ones who enjoyed the most the technological advances. Great to know the interest of youngest attendants in innovative solutions.
In our commitment to fight climate change, Cidaut is contributing to European Commission’s ambitious policies framed in Green Deal Initiative. The European Climate Pact is an EU-wide initiative inviting people, communities and organisations to participate in climate action and build greener Europe. This initiative is based on connecting and sharing knowledge, learning about climate change, and developing, implementing and scaling up solutions.
In this frame, Cidaut, together with 46 partners, participates in Probono European project. The vision of Probono is to create a people-focused European construction industry that works with a community of stakeholders to create sustainable positive and zero-carbon emitting green buildings and neighbourhoods. The consortium consists of construction actors, public asset service mangers, municipalities, technology solutions providers and experts to transform six European districts into green buildings and neighbourhoods.
The six districts are located in Madrid, Dublin, Aarhus, Brussels, Porto and Prague, where living labs will be implemented to validate Probono’s innovations. The living labs will provide experimentation and innovation environment and will allow testing different solutions for sustainable buildings, circular economy, material up-grading and electromobility. These solutions will be implemented in the coming five years.
The project will provide strong examples of green buildings and neighbourhoods’ technological and social innovation implementation by focusing on building infrastructure and exploiting digitalisation and smart technologies. Probono will create green buildings and neighbourhoods Strategic Planning Tools and provide evidence-based policy recommendations, standardisation actions, and robust adoption and commercialisation strategies. Project work will engage citizens in co-designing and co-delivering sustainable GBNs.
The research leading to these results received funding from the European Union (EU) project PROBONO (GA #101037075)
On 24th October 2011, Cidaut started one exciting jorney on board a Nissan Leaf. Since that day, the vehicle has been used as a laboratory for understanding the users’s acceptance, the influence of the weather and the driving style on the battery behaviour, the regenerative braking efficiency and so many other issues that have allowed our sustaineble movility and intelligent transport department to fix important knowledge to build many.
All the vehicle movements have been tracked to understand the influence of driving profiles, roads orography, weather conditions, battery temperature and vehicle payload on energy consumption. Also the charging processes have been monitored to evaluated the influence of low charging vs fast charging, battery temperature and voltage and current evolution along the charging.
Braking system has been instrumented to understand the influence of driving style and battery state of charge on regenerative braking working. Noise measurements in the interior and exterior of the vehicle have been performed and on board thermal analysis has allowed to understand some charateristics of the HVAC system.
The vehicle has been used by more than 200 drivers that have completed surveys and have participated in interviews to better understand the initial users’ acceptance to the electric vehicle use. This information has been valuable for Cidaut in order to advance in the evolution of several projects related not only with the electric vehicle, but also with the connected one.
Probono Project has been approved for funding by the European Commission in the Frame of Green Deal. Probono brings together 47 partners all around Europe to develop innovative energy efficient buildings in connected suitable green neighbourghoods.
To demonstrate the results achieved through the project two large scale demonstrators, Madrid and Dublin, and four living labs, Brussels, Porto, Aarhus and Prague, have been proposed across Europe. Cidaut will contribute with mobility, connectivity and integration of renewable energies in Dublin and Madrid.
The large scale demonstrators will focus on new buildings, retrofitting and green districts development, energy optimization at district level, integration in the grid and electromobilty. The project will provide support at city level and will interact with citizens looking for solutions to be reproduced in follower cities.
The living labs will focus on smaller scale business driven renovation or construction projects with clear definition of value proposition and also looking for solutions to be integrated in follower cities.
The project will start on Autumn and will last for 60 months.
In the field of the CERO Project, Cidaut has performed real time on board tests for vulnerable road users’ protection and short range communication. In the case of vulnerable users’ protection the tests have consisted in detecting both pedestrians and cyclist in different traffic scenarios, like overtaking, crossing or appearing behind big vehicles front blind points. The solution obtained is based in low cost components and simplified software. In fact, the system consists of a monocular webcam with a single processor to evaluate the images registered by the camera. The big effort has been made in the optimisation of the system program and in the use of artificial intelligence to teach the system.
All the scenarios tested were successfully completed, the different vulnerable road users were detected in advance and attending to their relative position with the vehicle trajectory the driver was advised accordingly. An important output of these trials has been the time needed for the system to register the image, process it and decide if it is a vulnerable road user or not. This time is 0,11 seconds clearly lower than the average reaction time of a human, 1 second, or the reaction time of a driver in alert situation, 0,5 seconds, and with the additional advantage of no distractions or drowsiness.
In parallel, the dedicated short range communication system developed in the project has been tested in different scenarios, the most relevant ones have been: semaphore communication, work zone + traffic jam and personalised messages for different users. In the first case communication between vehicle and traffic light, when the vehicle is approaching the traffic light, it communicates to the traffic light its speed and position, according to the time to red or to green, the traffic light makes a recommendation to the vehicle about how to proceed, immediately, the message appears in the HMI developed for the project. In the second case, the vehicle is alerted 500m in advance about the cut of one of the lanes of the road due to road works, and in the case of traffic jam due to the work zone, the vehicle is informed by the rest of the vehicles about this situation, as in the previous case, the corresponding graphic messages appear in the HMI of the vehicle. The personalised messages is aimed to substitute the large and costly (about 40 thousand euro) variable message signals in the roads. In this case the infrastructure has several pieces of information available for the users, but the users will only receive the information useful for them. For the test two vehicles were running on the track, the first one was an electric vehicle, and the second one a dangerous goods vehicle. The first vehicle received information about how to reach the closest charging station, while the second one was informed about a mandatory deviation for dangerous goods transport. The short range communication demonstrated to have more than 800 meters range and at the same time to be the best ally of the large range communication to warranty a seamless connectivity for the future autonomous vehicle.
