Problems solved by technology

[0007] A disadvantage of the known solution is that it is not possible to operate the air conditioner with a standstill or a standstill, since the belt drive cannot be mechanically decoupled from the crankshaft
However, due to installation space reasons, this clutch cannot be combined with a pulley isolator (RSE)

Embodiment Construction

[0030] figure 1 A Cartesian coordinate graph with x-axis 1 and y-axis 2 is shown. Represent time in seconds on the x-axis. On the y-axis the rotational speed is represented in a suitable unit. The area 3 below the x-axis 1 represents the parking air conditioning operation according to the invention. The area 4 above the x-axis 1 represents conventional parking air conditioning operation. Region 5 represents an engine shutdown phase.

[0031] Curve section 11 represents a conventional brake operated by a generator. Curve section 12 represents the reverse rotation of the auxiliary unit in parking air conditioning operation 3 according to the invention. Curve section 11 begins at a positive rotational speed 9 . The positive rotational speed may be the idling rotational speed of the internal combustion engine.

[0032] Curve section 12 begins at a negative rotational speed 10 . The negative speed 10 can be a negative idle speed. Curve section 13 represents the engine spee...

Abstract

A vehicle with an internal combustion engine, a belt starter generator (RSG) and decouplable auxiliary driven units for auxiliary units, wherein at least one air conditioning compressor and a The electric machine as belt starter generator is arranged in the auxiliary output as an auxiliary unit, which is characterized in that the auxiliary output is decoupled and coupled by means of a form-locking clutch, in particular a switchable pawl freewheel The device realizes; in the stop state of the internal combustion engine, during the brief shutdown phase, the parking air conditioning operation is carried out by means of the reverse rotation of the auxiliary unit, and, after the shutdown phase, the starting of the internal combustion engine is carried out by means of the reversal of the direction of rotation of the electric machine.

Description

technical field [0001] The invention relates to a vehicle with a belt starter generator (RSG) and a decoupled auxiliary output, in particular for a restart strategy in combination with a parking air conditioning drive and a switchable pulley. Background technique [0002] Vehicles with belt starter generators are known which are characterized by: [0003] a) Rigid pulley with torsional vibration damper (TSD) [0004] b) Pulley decoupler (RSE) with torsional vibration damper [0005] c) Magnetic clutches for friction locking of auxiliary units [0006] Only in variant c) can the operating point of the disengaged crankshaft be indicated. However, due to the installation space, it cannot be combined with the pulley decoupler. Starting from the parking air-conditioning operation as a so-called impulse start, the internal combustion engine can be started directly by means of a friction clutch. [0007] A disadvantage of the known solution is that it is not possible to operat...
