发明名称 Method and Device for Detecting Leaks in a Motor Vehicle Air Spring Arrangement
摘要 Disclosed is a method for detecting leaks in an air spring arrangement ( 1 ) in a motor vehicle, having a ride level control device which has a plurality of air springs ( 2 a , 2 b , 2 c , 2 d), devices ( 5 a , 5 b , 5 c , 5 d , 6, 12, 14 a , 14 b , 14 c , 14 d) for determining the total quantity of air in the air spring arrangement ( 1 ), and devices ( 15 a , 15 b , 15 c , 15 d , 16, 17 ) for sensing the temperature, and a device for carrying out the method. According to the invention, in the method there is provision that the total quantity of air Q<SUB>1 </SUB>at a first time t<SUB>1 </SUB>and the total quantity of air Q<SUB>2 </SUB>at a second time t<SUB>2 </SUB>are determined in the air spring arrangement ( 1 ) and are corrected by a temperature-dependent factor which is obtained by sensing the temperature of the air which is located in the air spring arrangement and forming the difference between the total quantities of air Q<SUB>1</SUB>, Q<SUB>2</SUB>, which have been temperature-corrected, so that when the difference is exceeded by a specific limiting value Q<SUB>limit </SUB>a leak is detected in the air spring arrangement ( 1 ).
