Embodiment Construction

[0020] figure 1 Motor vehicle 1, ie a coupe 2, is shown schematically. The passenger car has a drive unit 3 with an internal combustion engine 4 and a continuously variable transmission 5 . Connected downstream of the internal combustion engine 4 is an exhaust gas line 6 which is preferably equipped with a front silencer 7 and / or a final silencer 8 . The power of the internal combustion engine 4 is directed via the continuously variable transmission 5 to a drive train 9 , for example by means of a cardan shaft 10 , to the rear wheels 11 of the vehicle for their drive. Driver 12 can transmit a torque request or a torque request to internal combustion engine 4 via an accelerator pedal 13 known from the prior art. In addition, the motor vehicle 1 also has a device 14 for generating a simulated running noise 22 of the power unit 3, where the device 14 is connected to the accelerator pedal 13 via an interface of the device, via suitable electrical connections 15 and / or Or it is...

Abstract

The present invention relates to an arrangement for generating a simulated operating noise of a vehicle drive unit, comprising the drive unit that has a continuously variable transmission, a noise generator, and a noise output device. The noise generator (16) generates or influences the operating noise (22) independently of the actual speed (rr) and / or the actual load of the drive unit (3). The invention further relates to a vehicle (1) comprising such an arrangement (14) and a corresponding method.

Description

[0001] The invention relates to a generating device and a generating method for simulating running noise of a power plant of an automobile. The car has: a power plant equipped with a continuously variable transmission; a noise generator; and a noise output device. [0002] background technology [0003] The running noise of the vehicle (the "sound" of the vehicle) can be influenced with a system that is equipped, for example, with an electronic control unit and a loudspeaker at the exhaust outlet. The running noise of a car can also be simulated electronically. Such a simulation of operating noise as a function of a given or assumed rotational speed of the drive unit is known, for example, from US Pat. No. 6,859,539 B1. [0004] There are continuously variable transmissions for automobiles on the market, which can realize a continuous, ie non-graded, speed change of the vehicle power unit. In order to give the driver a familiar driving experience and driving noise, some trans...
