Conti develops autonomous vehicle for tire braking tests
Automated, electrical machine enables “precise monitoring” of friction characteristics
Hanover, Germany – Continental AG has produced a driverless and fully electric powered examination motor vehicle designed for measuring the braking overall performance of passenger motor vehicle tires.
The AVA – analytic car AIBA – enables exact monitoring of the frictional attributes of tires in the course of braking manoeuvres on dry and soaked streets, reported Conti in a statement 2 May.
The equipment, reported Continental, brings together the pros of a model-unbiased take a look at process with the controlled and reproducible check surroundings of its automated indoor braking analyser (AIBA).
The AIBA has been in procedure considering that 2012 and provides a 75-metre exam monitor, in an air-conditioned spot and up to 5 highway surfaces for brake testing.
With the new vehicle, Continental said it can now execute exams irrespective of motor vehicle precise qualities.
“With this, Continental has just one of the world’s most superior and precise tire braking exam methods,” it additional.
Continental’s flagship R&D centre Contidrom in the vicinity of Hanover, Germany, now residences the vehicle.
“Our analytic automobile AVA allows us to analyse the efficiency of our top quality tires in even higher detail and systematically build them,” defined Dr Boris Mergell, head of tire R&D.
For tire braking checks, the AVA is accelerated to a check velocity of 65 km/h with the aid of an electromagnetic linear drive, which is derived from roller coaster technological innovation.
Then, a number of absolutely automatic braking tests are carried out.
The AVA push method is outfitted with two electrically driven axles, which are driven by a high-efficiency battery.
The substantial maximum torque, Continental said, assures that a continual velocity can be taken care of, though the exam tires on the 3rd axle can be systematically braked.
The integrated braking process of the AVA is outfitted with “brake-by-wire technology” from Continental’s automotive business sector.
Unlike common hydraulic braking techniques, the technology transfers braking sign electronically.
In this article, Continental said, the brake reaction is “very speedy and precise”, which is vital for exact testing or measuring.
“Our AVA determines the transmission of forces in between the tire and the street surface area, while different slipping states, so-referred to as ‘µ-slip curves’, are precisely reproducible,” explained Meletis Xigakis responsible for world-wide tire tests.
“With the… engineering we measure all of the forces which act between the tire and the road area all through braking,” he extra.
The facts developed from the test will empower Continental to look at its tires and their several compound compositions “even additional precisely” and assist it optimise them for their exclusive works by using, Xigakis included.
