The ECOCHAMPS project addresses topic GV-4-2014, Hybrid Light and Heavy Duty Vehicles. The work will, in a single coordinated project, address all aspects of this topic and will be conducted by 26 partners representing the European automotive industry (OEMs (EUCAR), suppliers (CLEPA), ESPs and universities (EARPA)) including members of ERTRAC and EGVIA. The objective is to achieve efficient, compact, low weight, robust and cost effective hybrid powertrains for both passenger cars and commercial vehicles (buses, medium and heavy duty trucks) with increased functionality, improved performance, comfort, safety and emissions below Euro 6 or VI, all proven under real driving conditions. The five demonstrator vehicles, for this purpose developed to TRL 7, that use the hybrid powertrains will among other give a direct cost versus performance comparison at two system voltage levels in the light duty vehicles, and include the modular and standardized framework components in the heavy duty vehicles. Achieving these innovations affordably will strengthen technical leadership in powertrains, enable a leading position in hybrid technology and increases the competitiveness of European OEMs. The vehicles will be ready for market introduction between 2020 and 2022 and (price) competitive to the best in-class (full hybrid) vehicles on the market in 2013. More importantly, the technology devised will impact on the reduction of CO2 emissions and the improvement of air quality. The project proposes to reach a 20% powertrain efficiency improvement and a 20% powertrain weight and volume reduction, with a 10% cost premium on the base model for the demonstrator. To meet air quality targets the project will prove, via independently supervised testing, real driving emissions at least below Euro 6 or VI limits and by simulation show the potential of the passenger car technologies to reach Super Low Emission Vehicle standards.

In order to realize sustainable mobility in Europe, both urban and long distance vehicles for road transport will have to be significantly more efficient by 2020\ and a considerable contribution will have to come from the energy efficiency improvement of the powertrain. Moreover, together with the progressive efficiency increase coming from the engine technology evolution, the use of Low-Carbon Alternative Fuels, such as Natural Gas, will play a fundamental role to accelerate the process of decarbonization of the transportation sector that in Europe is targeted for the 2050 time horizon. In this context, being well-known the benefits of the Natural Gas Vehicles adoption in Europe, this proposal aims to exploit the main benefits of gas-powered engines developing CNG-only, mono-fuel-engines able to comply with: post Euro 6 noxious emissions 2020\ CO2 emissions targets new homologation cycle and Real Driving conditions and simultaneously improving engine efficiency and vehicle performance also with regard to its CNG range capability. These engines, based on new combustion processes, require also dedicated technological solutions for: Innovative injection, ignition and boosting system concepts Advanced exhaust gas aftertreatment system Detecting the gas-quality and its composition The results obtained from the experimental activities on the demonstration vehicles and engines will be harmonized and analysed throughout a final overall assessment of the different approaches. The demonstrator vehicles will be assessed in terms of performance and emissions with regard to NEDC, WLTP and under real driving conditions. Moreover, the final assessment of the vehicles will be certified, as independent testing, by JRC (Joint Research Centre) which will carry out additional measurements in their own testing facilities both on chassis dyno and by means of PEMS (Portable Emissions Measurement System).


Disclosed are a method of correcting a control logic of a selective catalytic reduction (SCR) catalyst and an exhaust system. The control logic may be adapted to calculate an injection amount of a reducing agent for the SCR catalyst at the least. The method may include detecting input variables including temperature of the SCR catalyst and exhaust flow rate, discretizing the input variables, standardizing the discretized input variables, determining whether the discretized input variables are within a correction range, and correcting the control logic of the SCR catalyst if the discretized input variables are within the correction range.


Disclosed are a method of determining a correcting logic for a reacting model of an SCR catalyst, a method of correcting parameters of the reacting model of the SCR catalyst and an exhaust system to which the methods are applied. The reacting model of the SCR catalyst is defined by m parameters and has n input variables, where m and n are natural numbers with n smaller than m. The reacting model of the SCR catalyst may be adapted to predict nitrogen oxide (NOx) concentration at a downstream of the SCR catalyst at the least.


A method of determining suitability of correction for a control logic of a selective catalytic reduction (SCR) catalyst, may include determining a suitability function of the correction based on a previous error and a current error when the correction has been performed, determining a suitability coefficient based on the suitability function of the correction, determining whether the correction may be suitable based on the number of corrections and the suitability coefficient, and resetting the control logic when the correction may be not suitable.
