H2020-IoT-03-2017 - Integration -Y- platforms: industrial partners sought for an innovative prototypal suspension system for vehicles
Summary:
Large Italian international company committed to the design and production of hi-tech systems and components for the automotive sector is looking for industrial partners for a H2020- IoT--03-2017 integration -Y- platforms project whose goal is to develop an innovative prototypal suspension system for vehicles, able to perform the functions of continuous damping control, suspension height adjustment, and regeneration of the kinetic energy of the suspension into electric energy.
Description:
The goal of this project is to develop an innovative prototypal suspension system for vehicles, able to perform the functions of continuous damping control, suspension height adjustment, and regeneration of the kinetic energy of the suspension into electric energy. The project aims at designing, manufacturing and testing into a demo vehicle the whole prototypal system, composed by suspension actuators, sensors integrated in those actuators, dedicated control electronics for damping and height control and energy recuperation, intermediate energy storage devices at 48 V, DC/DC converters to manage the energy flow to the vehicle battery.
In addition, the project aim includes also vision systems, and HMI for the customization and tuning of suspensions control. ADAS systems are more and more used in automotive to assist the driver in performing his tasks, and their diffusion will further increase in the context of the Autonomous Driving. Vision systems, such as cameras or radars, are the main sensors used to recognize the driving scenario by means of the identification of the environment around the vehicle.
Moreover, many authors in literature believe that Autonomous Vehicle will require the use of semi-active suspensions (electronic shock absorbers) or active suspensions, since the main requirement for such vehicles will be the passengers comfort. In fact, when the driver will not have any more the task of drive the vehicle, during travels he will be allowed to do other things, like work at computer, read books, rest, etc., and so the requirement of comfort will be more stringent than today.
On the other hand, especially for certain typologies of sporty oriented vehicles and users, it is still very appreciated the possibility for the driver and the passengers to interact with the main systems controlling vehicle dynamics, by customizing and tuning their way of intervention.
In this complex context, this project proposes to develop an integration between controlled suspensions, like semi active or active suspensions, front vision systems, like Stereo Cameras or Radars, and user interfaces allowing the communication with suspensions control logics, like an App to be uploaded into a tablet or a smartphone.
A system able to scan the road surface in front of the vehicle will be used to recognize large and isolated obstacles on the road and use this information to pre-set in advance the suspensions control system. Nowadays, all the traditional suspension control systems, without vision means, can recognize the road obstacles only after the impact against them of the front wheels. Accordingly, the damping control of the front wheels is not very effective, because the control actions are typically taken with a certain delay, and that has negative effects on passengers comfort and road holding. As opposite, by means of front vision systems, the recognition of obstacles can be performed in advance, thus allowing to pre-set the control actions on suspensions and improve both passengers comfort and road holding. Further improvements are possible, for instance by exploiting the synergies between front vision systems and High Definition GPS Maps. Finally, when the accuracy and the resolution of front vision systems will be so high to allow the recognition of discontinuities with height in the order of magnitude of the millimeter, it will be possible to perform a fine scan of the road profile for the identification of its roughness. With such performance, front vision systems will allow to control suspensions without using other additional sensors, like the vertical accelerometers or the suspension stroke sensors typically used today; that will allow the reduction or even the elimination of these sensors, and thus a cost reduction.
Advantages and Innovations:
Nowadays, a system able to integrate all these functions does not exist into the market: semi active shock absorbers for damping control, and lifting systems for height adjustment control, are already present into the market, but as independent and not integrated systems, while regenerative dampers, to convert suspensions energy into electricity, do not exist at all. An integrated system, as proposed, will allow to exploit the synergies between components to minimize weight and cost and optimize energy savings.

Estimates indicate that regenerative dampers can reduce the CO2 emission of cars up to 2.5 gr/km, while height adjustment can improve aerodynamics allowing a CO2 saving of 1 gr/km. Therefore, the impact of such an integrated system on the CO2 saving will be relevant.

Moreover, the integration of sensors inside the shock absorbers, like suspension stroke sensors or pressure sensors, will contribute to the evolution of such components toward smart actuators, able to send useful information to the vehicle communication network about the status of the actuator itself, or the status of the road the vehicle is moving on. Among the possible information which can be derived on the road status, we can mention the detection of isolated obstacles, like bumps or potholes, and the measurement of their dimensions, the identification of the average level of roughness of the road, a precise measure of body roll during cornering and body pitch during braking/accelerating, etc.. All these information can be used within the vehicle itself, for instance to optimize the intervention of other active control systems like the ABS or the EPS, or can be sent to other vehicles or to the road infrastructure, following a V2X communication scheme.
