An attractive electrical vehicle at an affordable toll that provides security as well as comfort combined amongst a reasonable driving range: that was the destination of the Visio.M project. The participating researchers at the Technische Universitaet Muenchen who set together the automobile inwards collaboration amongst specialists from manufacture are forthwith unveiling it to the public.
More as well as to a greater extent than people are considering the buy of an electrical car. Whenever possible, it should run on renewably generated electricity. They desire to conserve fossil resources as well as brand a contribution to the surroundings – piece playing the role of pioneers inwards an unstoppable tendency over the adjacent few years.
In the Visio.M collaborative projection researchers at TU München, together amongst experts from manufacture lead maintain been exploring what an all-round, sporty, low-price as well as rubber electrical automobile powerfulness human face like. The resultant of the undertaking, which has been funded past times the German linguistic communication Federal Ministry of Education as well as Research for ii as well as a one-half years to the melody of 7.1 1 G one thousand euro is a real small-scale vehicle that sets novel standards regarding efficiency as well as safety. The researchers volition unveil their automobile to the populace at the eCarTec from 21st to 23rd Oct 2014.
Speedy lightweight
The Visio.M has a driving arrive at of roughly 160 kilometers as well as infinite for ii people as well as luggage. With only xv kilowatts of engine power, the automobile tin give the sack attain a acme speed of 120 km/h (75 mph). Its pattern is sporty as well as self-confident. The features fulfill all pregnant requirements of a normal car, from infotainment as well as navigation assistance to climatization.
The electrical motor draws its liberate energy cast a 13.5 kWh lithium-ion battery comprising consumer cells as well as is mounted behind the seats. The battery weighs nearly 85 kg as well as tin give the sack live charged from a 230 V socket inwards only 3 to 4 hours. The full cost of ownership, including initial investment as well as operating costs, volition live lower than that of a comparable combustion engine car.
Decisive for the slap-up liberate energy efficiency of the Visio.M is its low-cal weight. The rider compartment is made of carbon fiber reinforced plastic amongst aluminum inwards the front end as well as bring upward sections, as good as the roof frame. All windows are made of polycarbonate. This cloth weighs only one-half as much as drinking glass but, cheers to a special coating, is as resistant to scratches as well as weathering. The researchers besides saved weight inwards chassis, steering as well as transmission past times using special light-weight constructions. Without the battery, the Visio.M weighs only 450 kilograms.
"Light weight is essential for an electrical vehicle," says Prof. Markus Lienkamp, Chair of the TUM Institute of Automotive Technology, "because to a greater extent than weight requires to a greater extent than battery performance for the same arrive at as well as hence generates higher costs. More weight besides agency poorer driving dynamics at the same performance. But nosotros desire a automobile that is affordable as well as fun to drive."
Safety first
An all-round, volume marketplace topographic point automobile must guarantee effective rider safety. Especially inwards collisions amongst heavier vehicles, small-scale cars must supply a security zone inwards spite of their small-scale dimensions. The rider compartment of the Visio.M consists of an innovative, multi-section monocoque made of carbon fiber reinforced plastic combined amongst ultra low-cal sandwich materials imparting it amongst exceptional rigidity.
In addition, the engineers lead maintain developed a security concept that includes a systematic anticipatory analysis of the surrounding traffic. The 360° monitoring of the immediate vehicle vicinity via radar as well as photographic boob tube camera sensors makes it possible to uncovering critical driving situations early on. This data is non used for driver assistance or warnings. When the automobile detects an imminent unavoidable collision it activates the integrated rider protection systems only earlier the actual crash takes place.
Novel structural airbags are mounted inwards the bumpers as well as doors. Fractions of a minute earlier a crash a gas generator fills these pressure level tubes, which so deed as additional absorption elements.
Adaptive seat-belt tensioners as well as forcefulness limiting systems cut the forces acting on the passengers. Influenza A virus subtype H5N1 two-point belt combines amongst the normal security belt holds the passengers firmly inwards their seats. When the organisation detects an imminent side collision, the rider on the crash side is pulled toward the within of the vehicle together amongst the topographic point only earlier the collision, thereby moving away from the immediate danger zone. The pre-acceleration of the rider reduces the crash forces acting on the rider as well as increases the effectivity of the side airbag. Influenza A virus subtype H5N1 potential collision betwixt the driver as well as rider is prevented past times an interaction airbag mounted betwixt the seats.
Ergonomic design
In contrast to conventional cars inwards which the heel of the driver is defined as a fixed indicate for the adjustment functions, inwards the Visio.M the driver's eyes serve as a fixed point. This allowed the researchers to topographic point the security systems as well as the traffic perspective optimally. The driver's topographic point must only live adjusted vertically. In telephone substitution the pedals are adjustable.
Control elements for the radio, air-conditioning as well as navigation assistance are accessible via a fundamental touching on display, which is besides adjustable. The human-machine interaction consists alone of swiping gestures that tin give the sack live made on the entire display. The driver does non involve to hitting whatsoever buttons as well as a quick glance is sufficient for visual orientation.
At the nub of the organisation is an opened upward software architecture that tin give the sack live extended at whatsoever fourth dimension amongst additional elements. This opens the door to things similar accessing dwelling music collections via cloud applications or performing compute-intensive applications similar energy-efficient road planning based on electrical flow conditions as well as traffic conditions from a fundamental server. All kinds of premium services tin give the sack live implemented inwards this way. In the future, for example, a rental automobile powerfulness live delivered to a customer's door via remote control. This concept has already been implemented experimentally.
Large driving range
Many aspects must live brought together earlier the vehicle tin give the sack attain a large driving arrive at inwards spite of its relatively small-scale battery. These include low-cal weight, depression aerodynamic drag, an efficient drive train, minimal rolling friction as well as energy-saving air conditioning. The researchers lead maintain optimized these parameters inwards the context of the Visio.M project. Thus the 1.55 m broad as well as 1.31 m high two-seater forthwith has first-class aerodynamics. In add-on to depression vehicle weight, the combination of depression coefficient of drag of only 0.24, small-scale frontal expanse of 1.69 foursquare meters as well as tires optimized for depression rolling resistance (115/70 R 16) farther cut the liberate energy consumption.
The active "torque vectoring" differential besides contributes to overall efficiency: Influenza A virus subtype H5N1 small-scale electrical machine inwards the gearbox that tin give the sack live operated as an electrical motor or as an electrical generator distributes the forcefulness optimally betwixt the ii dorsum wheels. Because of the improved stability piece braking inwards curves, significantly to a greater extent than liberate energy tin give the sack live recovered than without torque vectoring. At the same fourth dimension the automobile becomes much to a greater extent than agile as well as safe, because of the optimal distribution of drive advertising braking forces.
Energy-saving air conditioning
Special attending was paid inwards the Visio.M to the pattern of the air-conditioning as well as heating systems. Wherever warmth is generated, it is recovered for heating the automobile when required. So-called Peltier elements are integrated into both the cooling aggregate as well as seats. These electrothermal converters tin give the sack oestrus as good as cool. This allows environmentally friendly functioning without the exercise of coolant fluids. During real mutual coldness conditions an ethanol-based heater tin give the sack live switched on for driving arrive at independent heating. The aggregate amongst a thermal performance of approx. 4.5 kW is peculiarly useful for deicing the windscreen. An intelligent controller finds the optimal solution for liberate energy efficient as well as comfortable functioning of the air-conditioning system.
Electromobility for the masses
During the evolution of the Visio.M, the diverse systems were champaign of report to numerous trials to testify their functionality, security as well as reliability. The resultant is an electrical automobile that should uncovering slap-up interest, peculiarly inwards industry. Prof. Markus Lienkamp is optimistic: "With the Visio.M nosotros lead maintain demonstrated that it is possible to build a real low-cal as well as at the same fourth dimension rubber automobile amongst overall costs that nosotros human face to live lower than those of comparable combustion-engine cars. But it is nonetheless a long way to series production because nearly all components must live adapted to the manufacturing conditions of large series."
