Moose test

As moose test ( driving dynamics test) is called a maneuver that simulates the evasion of a sudden obstacle on the road. With the test, the driving stability of passenger cars is checked. With speeds of about 50 km / h and 80 km / h to change lanes to the left and, after a short straight track, a lane change is driven to the right unabated. The vehicle should neither break nor fall over sideways.

The term was coined Elchtest the end of 1997 through the press after a Mercedes -Benz A-Class upset by journalists in Sweden during a test. Originally called the test in Sweden children test. The term 'elk test a collision test of the vehicle is denoted by a (simulated) moose. Saab Automobile and Volvo perform such tests to ensure the stability of the A-pillar and the roof over one impacting elk.

General

The moose test offers due to its large, constant lanes widths a wide scope for the driver's steering strategy. The Association of the Automotive Industry (VDA) has therefore designed an alternative test in which the lanes widths of the vehicle width are dependent. Next, the gas removal is required in the first lane. This maneuver has now been adopted under the designation ' VDA lane-change test ' in the international standard ISO 3888-2. It is part of the testing of the handling characteristics of new vehicles. With a special charging tip of the elk test is partially carried out in trucks.

A vehicle equipped with ESP is evasive tests such as the elk test much more stable than a vehicle without ESP. From November 2011 onwards, all new car and truck models, which are approved in the European Union, be equipped with ESP. From 2014, this applies to all new vehicles, even if the series itself is on the market for several years.

History

The term Elchtest received a high level of awareness, as on 21 October 1997, a vehicle of the type " Mercedes -Benz 168 series " (then the most recent product of the Daimler -Benz AG) tipped in a test in Sweden on the page and finally on the roof remained lying. As a consequence, Daimler- Benz built the standard Electronic Stability Program ( ESP ) is a - then a novelty outside the luxury class. The reputation of the A-Class was initially nevertheless struck.

Tests with other cars

The newspaper Thüringer Allgemeine the elk test resulted in 1997 with a Trabant 601 by, this was the test at 75 km / h

Another example is the Dacia Logan, who initially had apparently failed the moose test in July 2005. However, it was not a question the standardized elk test, but a road test of ADAC. The spacing between the lane changes were increased and the rate was increased, thereby leading to the tipping over to the partial draining of the tire from the rim. In retrospect, this test proved to be inconclusive because the tires of the vehicle concerned had already been damaged by various previous extreme tests.

In October 2005, the BMW E60 was how the Swedish magazine Teknikens Värld reported tested in the Swedish Bromma and showed a breaking of the stern. This was seen by BMW as planned late intervention of the ESP.

In June 2007, tipped the Land Rover Defender, a classic that has been built for over 60 years. This was due to its high center of gravity and the lack of ESP.

The ADAC performs its own alternative test that can be driven at higher speeds. In 2010, the three nearly identical cars Citroen Nemo, Peugeot Bipper and Fiat Qubo were tested at a speed of 80 km / hr. Nemo tipped when tested at 80 km / h around. Citroen said to immediately equip the vehicles from Autumn / Winter 2010 with ESP. The Qubo, who owned the optional ESP during the test, passed the test and at 90 km / h For safety reasons, the test on Peugeot Bipper has not been carried out.

Since 1999, the Citroën Xantia Activa V6 is the record holder of the moose test Teknikens Värld at a speed of 85 km / h He placed himself so that, in spite of the absence of ESP, before cars such as the Porsche 911 GT3, or Audi R8.

In particular, road transport vehicles with high center of gravity, because of their height ( vans, SUVs, SUVs, vans and minivans ) during extreme maneuvers around its longitudinal axis tilt (to the side fall ). This has physical reasons and is therefore independent of manufacturers and price.
