The German luxury car Audi works relentlessly on new systems that enable their engines consume less fuel and be kinder to the environment. Now, the house with the four rings is developing a similar technology to that used hybrid vehicles to conventional engines off when not needed.
The technology known by the acronym iHEV (Intelligent Hybrid Electric Vehicle), could be combined with the efficiency predictor assistant (PEA) to achieve dramatic reductions in consumption, turning off the engine when not needed. In this case, if the function is activated decoupling or 'coasting' off the combustion engine. In the task of restarting the combustion engine handles an electric motor of 48 volts of power, built-in transmission and driven by a belt.
Meanwhile, a lithium ion battery of 48 volts and also resistant to charge and discharge cycles guaranteed supply of energy during engine shutdown, to power items such as power steering, air conditioning or team booster. The electric motor is used to restart the combustion engine when driving is responsible for maintaining the charge this battery.
Along with assistant predictor efficiency, iHEV vehicles can realize its potential efficiency, as demonstrated by the comparative runs were conducted with different prototypes, using as vehicles Audi A7 Sportback and Audi A8. During testing, the A7 Sportback 3.0 TFSI iHEV has covered several times a circuit of 61 km long and curvy road development north of Ingolstadt (Germany) in a typical everyday driving mode.
In the tests, which were conducted without the support of efficient predictor assistant, the driver crossed the 28 percent of the way with the engine off. In combination with active signs of efficiency thanks to assistant predictor, this proportion rose to 43 percent, while consumption was reduced by 10 percent. However, the run time was extended by just 2 minutes (3 percent), ie the length of travel is maintained practically neutral.
In the future, network integration features of Audi connect will allow continuous updating of data state. When it detects an Audi with its video camera signal speed limits, for example in a new piece of work, coordinates and communicates the speed limit through the mobile phone network to a server computer center Audi. From there, and after confirming its accuracy, the information reaches all vehicles with the equipment because they will drive on the same route, this is a concrete example of application of the technology future car-to-X in which the brand the four rings working hard.
