Abstract
A motor vehicle having a chassis including an air spring system. The motor vehicle includes a high-voltage on-board electrical system and a high-voltage battery supplying electrical energy to the high-voltage on-board electrical system. The air spring system includes at least one air spring which is supplied with air at a respective required pressure via a pneumatic line connected to an air spring compressor. The air spring compressor is a high-voltage air spring compressor which is supplied with electrical energy via the high-voltage on-board electrical system of the motor vehicle. The air spring is supplied with air exclusively and directly via the high-voltage air spring compressor during operation of the motor vehicle.
