PART B: VALORISATION PLAN
|Please provide a short description of the state-of-the-art and/or current trends in the field? How does the result fit into it?|
|The proposed mounting aggregate is aiming to solve some basic safety and efficiency problems in vehicle driving performance.
At present this problem is solved particularly by the so called Electronic stability control (ESC) systems or similar – ESP, ASC, etc. – designed to help prevent the drive wheels from spinning while the car is accelerating, and monitors and compares the rotational speed of the drive wheels..
ESC triggers anti-lock brake (ABS) system, and all ESC-equipped vehicles are fitted with traction control. The ESC components include a yaw rate sensor, a lateral acceleration sensor, a steering wheel sensor, and an integrated control unit.
Availability of ESC in vehicles varies between manufacturers and countries. In 2007, ESC was available in roughly 50% of new North American models compared to about 75% in Sweden. However, consumer awareness affects buying patterns so that roughly 45% of vehicles sold in North America and the UK are purchased with ESC contrasting with 78-96% in other European countries such as Germany, Denmark, and Sweden. Nowadays increase of the number of vehicles with ESC is in place. Some of the manufacturers offer it as part of the base equipment..
The advantage of the proposed system is that it is a mechanical construction built almost entirely by standard automotive spare parts. It is simple and requires no electronics, sensors or complex hydraulics components.
It is very important to underline the flexibility of application that this device provides:
For vehicles that already dispose of the above described (computerized)control systems, the device could be installed to complement their performance and efficiency by increasing tire to road cohesion during dynamical processes of driving;
For the low-cost vehicle segment, the system could be an economic substitute of the of the “Dynamic control’” type systems;
The system is designed to be applied and operational simultaneously at the four wheels of the vehicle and it has shown efficiency in all road conditions in contrast to the currently applied analogues – for instance ESC system has to be disangaged when the vehicle is stuck in mud or snow, drived on a sand, or when a smaller-size spare tire is used, which would interfere with the sensors.
The mechanical lever (leverage) system is designed to mount the drive units in the vehicle in such a way that the power derived from the torque of the engine is always directed downward. This increases the traction of the wheels to the road surface and results in better balance of the vehicle, increases performance and reduces tendency to tilt. The effect is similar for both intense acceleration and deceleration leading to a significantly better driving control. To summarize the proposed invention solves and increases:
ü Drivetrain power balance
ü Stability and driveability of the car
ü Drivetrain dynamic balance
ü Energy efficiency
|What is the problem/need/knowledge gap that the research result is responding to? How was it addressed before?|
|The proposed invention is addressing a general problem of the overall vehicle safety and driving performance which currently is solved by a combination of complex electronic (including sensors and hydraulics) systems. The systematic measurements and tests, undergone so far has generated reliable results and indicate a better performance of this auto system in comparison with the current analogues.
Due to it concept and construction, the proposed system achieves better balance of the vehicle, increases performance and reduces tendency to side and longitudinal tilt. The effect is the same for both acceleration and deceleration leading to increased driving control. The proposed solution provides:
ü Reduced slipping/skidding of tires at start.
ü Decrease of breaking distance – accordingly, this proportion is expected to reduce the time for an intense acceleration at start and braking distance in emergency braking.
ü Improved stability and better driving on turns.
ü Higher overall safety.
Another very significant problem that the proposed invention solves is that due to mechanical concept and its positive effect on the power distribution, it leads to significant overall reduction of power consumption ( overall economy). This feature of the device is of high importance taking into account the hybrid and the electro-car trend and the interrelated sustainable product concept which prove to affect the global industry and market.
|What is the potential for further research?|
|The invention has a potential for various application in all automotive sub-sectors.
In short term, the researcher is willing to develop two market channels – as an industrial product for integration in the newly-produced vehicles and kits for car-tuning and optimization for vehicles already in use.
Sports and racing cars is a potential domain for application as the implementation of this innovation can lead to improvement of their parametres at relatively low cost and short mounting time.
The principle of this technical solution will be especially useful and more easily applicable for application in future electric vehicles..
|What is the proposed method of IPR-protection? (patent, license, trademark etc.)|
|The technical solution is a subject of national patent and its application is to increase the road traction by about 20%, proved by tests of simplified initial prototypes.
The researcher has started procedure for obtaining European and Canadian patent as well.
The challenges foreseen are with regard to maintenance of the patents and management of the regions of validity.
|What are the steps that need to be taken in order to secure the IPR-protection? What is the cost of IPR-protection?|
|Support the application with patent maintenance – international protection requires substantial resources. Another challenge is the expansion of the regions of protections as the technology shows potential for application in global scale.
A specialized consultancy on intellectual property management is necessary as the nature of the invention suggests as a main direction for realization is industrial application and therefore partnbership for licensing is the most desirable form of developing the proposed R&D.
|What is you overall assessment of the scientific maturity of the research result?|
|The scientific maturity of the proposed technical decision is at prototyping stage. It represents an iingenious idea with extremely simplified construction showing high results in terms of optimization and safety, theoretically and practically proved. The construction and simplified design lead to low cost and easy implementation in the present-day automobiles wich proves a significant market potential.
The invention is already in process of national and international (European and Canadian) patenting.
