Definitions

  • the invention relates to a motor vehicle with electric drive.
  • motor vehicles There are known purely electric motor-powered vehicles as well as hybrid motor vehicles, which can be operated by internal combustion engine and alternatively or additionally also by electric motor.
  • Electric motor driven vehicles are very quiet, especially during slow driving, for example in a residential area. This results in an increased risk of accidents for passers-by, especially when passers-by expect a loud noise of an internal combustion engine when approaching a motor vehicle.
  • a solution to this problem suggests, for example, the
  • DE102007003201 A1 has a device for noiseless or almost noiselessly moving vehicles, which generates an audio signal that can be heard by other road users.
  • it is often proposed to simulate the noise of a conventional internal combustion engine with the audio signal.
  • the advantage of a lower acoustic emission of the electric vehicle is abandoned.
  • it is often suggested in this context to use an electrodynamic loudspeaker for Schallab- radiation but due to its position in the engine compartment in the lower audio frequency range can only have a limited performance and its use relatively high power (about 300 watts) requires ,
  • the invention is based on the object of specifying a motor vehicle with an electric motor, by means of which acoustic signaling required to reduce the risk of an accident is output with little effort. This object is solved by the features of the independent claim. Advantageous developments of the invention can be found in the dependent claims.
  • An electrically drivable motor vehicle comprises an electrodynamic converter device for, in particular acoustic, excitation of a body surface, in particular a body surface movable relative to the vehicle, preferably a bonnet or a trunk lid, and a control device which is set up and coupled to the transducer device the body surface is excited to produce an acoustic signal.
  • the acoustic signal is preferably a warning signal or a warning sound, which is automatically output when the motor vehicle is not acoustically or only badly perceptible due to the electromotive operation of passers-by.
  • a motor vehicle can be acoustically well perceived by passers-by, even at low speeds, in electric motor operation.
  • the generation of signals can be implemented particularly economically in practice, since the sound source is realized by an already existing body surface, and the excitation can take place by means of a known electrodynamic transducer produced in large numbers.
  • the realizable with the invention bandwidth of the audio signal is greater than in a conventional, realizable in the engine compartment speakers.
  • the space requirement and the additional weight for the implementation of the invention is limited to the electrodynamic converter and optionally the control device.
  • the generated audio signal is executed in such a way that technical or regulatory requirements with regard to the audio signal to be output by an electric vehicle are met in terms of frequency and volume.
  • the audio signal is as quiet as possible, in particular significantly quieter than the noise of an internal combustion engine or a simulated internal combustion engine.
  • control unit has a data input for receiving speed information, which the motor vehicle anyway detects and provides, for example via a data bus.
  • the control unit is set up such that the acoustic signal generated by the body surface becomes quieter with increasing speed.
  • the motor vehicle includes an output stage amplifier device for suitable generation of an acoustic signal.
  • the invention is particularly advantageous when used in a hybrid vehicle, which thus provides not only the electric motor but also an internal combustion engine for additional or alternative drive of the vehicle.
  • the converter device is preferably automatically deactivated when the internal combustion engine is put into operation, and / or when the internal combustion engine is at rest or substantially at rest (engine speed is lower than the engine speed).

  • a program-controlled control device is set up in such a way that signals for the response of the converter device are generated by an integrated output stage amplifier device depending on different input information and transmitted to the converter device.
  • the control unit comprises, for example, a functional unit with which the converter device and / or a sound generator (signal or noise generator) are adapted to the mechanical conditions of the body to achieve the same playback characteristics on different vehicles.
  • a sound generator signal or noise generator
  • Input information may be, for example: operating state of the electric motor, operating state of the internal combustion engine, rotational speed of the internal combustion engine, vehicle speed, environmental information from an environment detection system or from a navigation system, etc.
  • control unit can now be set up so that starting from a switched-off, stationary hybrid vehicle, the converter device is addressed by switching on or ready switching of the electric motor such that a low-frequency background noise is generated by the engine hood.
  • the converter device of the electric motor is addressed such that alternatively or in addition to the background noise an audio signal is output, which together with the speed-dependent other vehicle noise, such as wind noise, rolling noise, the minimum requirements legislator Specifications, especially in terms of level and frequency, met.
  • the artificially generated by the hood audio signal is quieter with increasing speed.
  • the internal combustion engine is activated to drive the hybrid vehicle, the converter device is deactivated or the converter device remains deactivated. If now the internal combustion engine is switched off again, the converter device is activated again when the electric motor is switched on and, depending on the operating state of the electric motor and the vehicle speed, is addressed again in such a way as described above.
