Claims31
A vehicle, comprising:
- an internal combustion engine;
- and
- an exhaust-gas system which has at least one first exhaust-gas tract with at least one first exhaust-gas outlet opening into surroundings and at least one second exhaust-gas tract with at least one second exhaust-gas outlet opening into the surroundings, wherein
- as viewed in a direction of travel of the vehicle, the at least one second exhaust-gas outlet is located in front of the at least one first exhaust-gas outlet,
- as viewed in a side view of the vehicle, the first exhaust-gas outlet is located in a rear vehicle half and the second exhaust-gas outlet is located in a front vehicle half,
- the first exhaust-gas outlet is located behind a rear axle of the vehicle,
- the second exhaust-gas outlet is located in front of a bulkhead of the vehicle and in front of a passenger compartment of the vehicle.
A method for open-loop or closed-loop control of a distribution of a collective exhaust-gas stream between a first and a second exhaust-gas tract of a vehicle having an internal combustion engine and an exhaust-gas system which has at least one first exhaust-gas tract with at least one first exhaust-gas outlet opening into surroundings and at least one second exhaust-gas tract with at least one second exhaust-gas outlet opening into the surroundings, wherein as viewed in a direction of travel of the vehicle, the at least one second exhaust-gas outlet is located in front of the at least one first exhaust-gas outlet, as viewed in a side view of the vehicle, the first exhaust-gas outlet is located in a rear vehicle half and the second exhaust-gas outlet is located in a front vehicle half, the first exhaust-gas outlet is located behind a rear axle of the vehicle, and the second exhaust-gas outlet is located in front of a bulkhead of the vehicle and in front of a passenger compartment of the vehicle, the method comprising the acts of:
- distributing the collective exhaust-gas stream dependent on at least one of:
- (a) a present drive power of the internal combustion engine,
- (b) a speed of the vehicle,
- (c) a spatial position of the vehicle, or
- (d) an acoustic signal which is measured in the passenger compartment or outside the passenger compartment or on the passenger compartment of the body of the vehicle.
