Next post deals with the design of the control logic of the hybrid powertrain southgate car centre vehicle VW Touareg Hybrid. The paper deals with the theoretical analysis of different strategies of cooperation between the combustion engine and an electric motor in a hybrid vehicle powertrain parameters with VW Touareg and assembling various driving modes. Vehicle model is created with parameters VW Touareg and compared 2 types of control logic: Efficient mode, Fuel - Use mode. These logics are compared in terms of fuel consumption and driving dynamics. The theoretically calculated southgate car centre values southgate car centre and the course we created a model of the entire drive mechanism proposed vehicle parameters VW Touareg Hybrid.
Hybrid technology, or combination of 2 or more different types of drives, not in the world of transport newsworthy. These included a diesel-electric locomotives and submarines of World War II. But the biggest expansion recorded hybrid technology nowadays. Teething problems, such as regulation of the combustion engine with a power transmission to the wheels (clutch, gearbox) with a combination of electric cars nowadays replaced the pressure on the increasingly stringent emission standards, minimizing fuel consumption and maximize streamline the entire propulsion system. The degree of "hybridization" We distinguish several kinds of hybrid drives. In today's ecological southgate car centre time largely extends the field of application hybrids, ranging from hybrid motorcycle through the entire automotive industry southgate car centre to freight. Particularly in urban transport, where precisely defined driving schedule may deploy hybrid technology appropriately to optimize operating strategy.
Block diagram of the hybrid system consists of several basic blocks. Had to be created model driving cycle. We used a standardized southgate car centre driving cycle NEDC is used to measure emissions and fuel consumption for European southgate car centre vehicles.
Driving cycle (driving cycle) - the simulations we used exactly difinovaný European NEDC driving cycle. This is a combined driving cycle, southgate car centre which consists of four urban driving cycles and an extra-urban driving cycle. The Fig.1 shows the use of the driving cycle NEDC (New Europen Driving Cycle).
Fuel converter (internal combustion engine) - contains a map of specific consumption, then recalculated the overall efficiency of the internal combustion engine. Maximum efficiency of chosen combustion engine is 36%. Map specific consumption is also bounded torque curve at maximum load.
Gearbox (transmission) - includes ratios of the individual gears with final gear ratio in the transfer case. It also contains data on the weight southgate car centre of the gear and its overall mechanical efficiency.
Energy southgate car centre storage system (battery) - this is a model of high-voltage 288V NiMH batteries. southgate car centre It contains data on nominal voltage, discharging characteristics, the number of cells and the total weight of the entire southgate car centre system.
The primary management objective parallel hybrid system is to keep the engine in such a load and speed, to work in areas with the highest efficiency. This increases the overall efficiency of the entire hybrid powertrain. This condition is best achieved using a Continuously Variable Transmission CVT ratio. In our case, the use of multi-stage gear, working area of the combustion engine depends on the load performance of the electric motor, gear engaged and the battery charge. For comparison, we used two control logic based on FUZZY:
Fuzzy logic controller (FLC) is used mainly for large non-linearity of time and the large number of variables southgate car centre upon which the entire managed system. FLC uses two main inputs: SOC - the battery charge status and the desired torque of the combustion engine. southgate car centre Based on these inputs and the chosen mode of management, FLC adjusts the operating point of the internal combustion engine. By equation (1) is then calculated by the torque of the electric southgate car centre motor. (1)
This mode limits the instantaneous fuel consumption of the internal combustion southgate car centre engine. This will ensure that the fuel consumption (g / s) does not exceed a certain southgate car centre value. This mode is not based on achieving the highest possible efficiency of an internal combustion engine, but this is mainly to limit consumption to a certain value. Threshold and fuel consumption depends on the requirements of the vehicle driving dynamics, maximum fuel consumption and battery charge. When you enter the required value of the marginal fuel consumption, FLC curve that translates into complete consumption characteristics of the internal combustion engine and ensure that the operating southgate car centre points of the internal combustion engine which operates are located on the border or below, see Fig. 5th
