Preventing from traffic jams with electronics and connected cars

Honda Motor announced the successful development of the world’s first technology to detect the potential for traffic congestion and determine whether the driving pattern of the vehicle is likely to create traffic jams. It's been developed in conjunction with the Research Center for Advanced Science and Technology at the University of Tokyo.

Rather than providing information to help the driver avoid existing congestion based on current traffic information, the system monitors the acceleration and deceleration patterns of the vehicle to determine whether the driver’s driving pattern is likely to create traffic congestion. Based on this determination, the system provides the driver with appropriate information, including a color-coded display through the on-board terminal, to encourage smooth driving which will help alleviate the intensity of acceleration and deceleration by trailing vehicles, thereby helping to prevent or minimize the occurrence of vehicle congestion.

The test results demonstrated that the system helped increase the average speed by approximately 23% and improved fuel efficiency by approximately 8% of trailing vehicles.

CESA 2012 interview : Guillaume Devauchelle (Valeo) part 3

Last but not least, this is the last part of our interview with the R&D director from Valeo. Guillaume Devauchelle speaks of hybrids with an exclusive technology.

"Given the CO2 regulations in Europe and US for 2020 and beyond, it is now obvious for the automotive community that hybridization of powertrains is no longer an option. Hybrid means breeding together an Internal Combustion Engine (ICE) and an electrical motor. The electrical motor allows to recover kinetic energy during braking in the form of electricity which is stored in a battery and made available for the next acceleration where the electric motor will provide extra torque to the ICE which, in turn, will need less fuel.

The problem with the hybrids is that they use a powerful electric motor to allow significant range of electric drive. To do this a high voltage is needed, which turns the battery big and expensive. The battery is the main on-cost of an hybrid, and all of them today suffer from an overcost and overprice which limits their market penetration.

Valeo's affordable hybrid concept is streamlined by 2 main concepts: First, to turn an hybrid cheap, the main lever is to reduce the voltage to reduce the cost of the battery. This requires to limit the power of the electric machine. Second, to use the long experience in StopStart micro-hybrids systems (that Valeo invented) using cheap, alternator-based, electric motor. Extensive simulations have shown that limiting the power to 12 kW allows to save up to 10-15% of fuel on the European cycle while allowing a low 48V voltage system. Also, limiting the electric drive to take-off and some low speed cruise operations allows to have a reasonably small battery pack.

Valeo's affordable hybrid system consists then in a Belt-Driven Starter Generator with 12 kW peak power, inherited from our former StARS StopStart system, together with a small 300Wh 48V battery and a 48V-12V DC/DC converter. All together the cost of the system is halved compared to traditional hybrids. Vehicles have been built to demonstrate this "right sized" system with value-to-cost optimization and OEMs have all shown high interest for this solution in the past months. We have no doubt this will turn hybridization into a real mass-market, why we have tagged our system "Hybrid4All".

CESA 2012 interview : Guillaume Devauchelle (Valeo) part 2

For CESA 2012, R&D director from Valeo speaks about the connected car and applications from smartphones.

"The connected car offers a new range of opportunities to increase safety & comfort as well as to reduce CO2 consumption. We are working on the embedded devices that will enable the car to be connected to its environment using all available wireless standards (GSM, LTE, WiFi, Bluetooth, RF...). We see the crucial role that the connected mobility of the end-user will have in this new paradigm.

We already demonstrated some examples on how the car's systems could evolve : last September 2011 with Park4 Remote at the IAA in Franckfurt (autonomous Parking Manoeuvre with a remote control on a smartphone) and in the first quarter of 2012 with eSkin (connected display of the future that allows you to use safely your smartphone computing power while driving for off-board navigation for example) and many more to come...

Valeo firmly believes that connected Driving Assistance systems will also further contribute to C02 reduction by reducing the travel time (increased flow, quick & direct access to parking) and by optimizing the powertrain energy management thanks to the available extended horizon offered by connectivity".

To be continued with next Valeo and Hybrid4All.

CESA 2012 Interview : Guillaume Devauchelle (Valeo) part 1

For CESA 2012, Guillaume Devauchelle, R&D director at Valeo, speaks about the new Vedecom Institute in Paris area.

"In a context of unprecedented global change in both the demand for and use of personal transportation, the Vedecom Institute aims to increase the energy efficiency of personal transport and to decrease the presence of harmful emissions in priority urban and suburban areas, by inventing new mobilities at the same time as new vehicles.

No industrial company, no services operator, however powerful, will be able to achieve this on his own. It requires the automobile manufacturers and suppliers, the higher education and research establishments, the territorial collectivities, the mobility operators, the infrastructure engineering companies and managers, the city planners, the economists, the sociologists to work together in inventing and deploying these new mobility systems. VeDeCoM creates such a strategic alliance, for the first time in the world.


The entire car industry is reaching out to stakeholders in mobility systems, information services, and energy sectors. Vedecom will bring together a unique set of global specialists with multi-disciplinary skills, at the same time and in the same place, providing them with the environment and structure so needed by a fledgling industrial sector with a bright future.

It is a threefold programme, electrification of vehicules, connectivity and driving delegation, architecture and services which aims at addressing the whole system issues, in a multidisciplinary manner: design of new vehicles, design of new ways of drives, from assisted driving to automatic driving, design of new technology blocks, from mechatronics power traction, security controls and telecom assisted connectivity, offering best potential for massive new system introduction, a mandatory objective for having the required impact on energy consumption. Demonstrations, on annual basis, also show progress and test user acceptance. The Vedecom Institute is a brand new organization that is set to become a benchmark in the blossoming sustainable personal mobility sector, in order to get an energy reduction by at least a factor of 2 over the next 10 years.

Vedecom displays a technological reference to support the design and implementation of the “Grand Paris”. Being located in the Satory region at the north of the “Plateau de Saclay”, VeDeCoM is already asked to participate to the definition of new “eco-quartiers” around the new Grand Paris metro stations in this area. The new systems will serve as demonstrators and later on as benchmarks for the whole public transportation network, in Paris and worldwide, providing excellent grounds for companies to export their experience, and for researchers to attract students and high level personalities in France".
