Definitions

  • the invention relates to a method for generating a tactile driver feedback regarding the operational readiness of a vehicle, in particular a hybrid vehicle.
  • Modern vehicles provide the driver due to their particular smoothness and very good decoupling of noise and / or vibration of the drive train very little or no feedback in terms of their operational readiness.
  • hybrid vehicles in particular, when they are operated with the electric motor, the operational readiness for the driver is not readily apparent. After pressing a start button or an ignition key while the vehicle is ready to drive, especially if at high high-voltage battery level, the engine of the hybrid vehicle is not used, but the vehicle is started directly with the electric motor and the vehicle is to be moved purely electrically; However, this operational readiness is not recognized by the driver without further ado.
  • a display presentation or a display of purely optical displays, such as signal lamps often not sufficient to the driver to display the operational state of the vehicle sufficiently accurate, especially not if the driver is, for example, in a stressful situation or inattentive.
  • the driver is in this case about the actual state of his vehicle, namely, whether he can start by mere kick on the accelerator pedal, not sufficiently clear.
  • the driver is provided a tangible driver feedback regarding the operational readiness of his vehicle, which informs him without a need for specific attention about the operational readiness of his vehicle.
  • a method for generating a tactile driver feedback regarding the operational readiness of a vehicle is proposed, in particular hybrid vehicle, wherein the driver feedback is generated depending on the state of a drive train of the vehicle.
  • Decisive for the operational readiness in the sense of a "driving off" is the state of the drive train of the vehicle, so in particular the available driving power on torque request of the driver.
  • the driver feedback is a vibration message.
  • a vibration message is one that communicates itself to the driver through vibration, ie through actively and passively perceivable changes in position of at least one object in space.
  • haptic vibrations come into consideration here, ie those which are actively felt by the driver and in which an active activity of the motor cortex is required, but in particular those which can be detected by way of the perception of passive stimuli. This considerably expands the range of sensible messages that may be considered, in particular requiring no active or even directed attention or active action by the driver. Namely, while the haptic perception an active feeling in the sense of a
  • the driver feedback is an acoustic message.
  • An acoustic message is in the broadest sense also a vibration message or includes a vibration message, but the vibration is at least partially carried out in a perceptible for the human sense of hearing frequency range or generated by human perceptible frequencies.
  • the acoustic perception is as well as the perception of a general vibration message unplayed, so it is in particular no active looking at the driver as required for an optical message.
  • the acoustic message is a modulated engine noise.
  • the engine noise is either stored or artificially generated, especially modulated by volume and frequency response, giving the driver the perception of a conventional internal combustion engine.
  • the driver habitually connects the available standing of the vehicle, in particular namely the readiness of the drive train to provide propulsion to the vehicle.
  • the driver feedback is preferably provided on a vehicle device in contact with the driver of the vehicle.
  • a vehicle device in contact with the driver of the vehicle.
  • all parts of the vehicle device as such into consideration, which are in contact with the driver. These are, in particular, those that he or she touches in a targeted manner or with which he or she is otherwise in contact, even unintentionally and without any specific intervention.
  • a steering wheel in a method training as a vehicle device, can be used, while in another method training alternatively or additionally as a vehicle device, a seat, in particular a driver's seat, is used.
  • a seat in particular a driver's seat
  • the embodiment of the method using the driver's seat is very advantageous because the driver is accustomed to draw conclusions about the state of the vehicle, the road and certain movement processes via stimuli mediated by and / or by means of the driver's seat.
  • the driver feedback is a continuous message. It is therefore continued.
  • the driver feedback is a time-limited message, ie one that exists only for a certain period of time. The period may be longer or shorter.
  • the driver feedback is a message repeated at certain time intervals, in particular periodically.
  • the driver is reminded at certain time intervals, in particular periodically, of the ready-to-operate state of the vehicle. This is particularly advantageous for longer life, for example, in front of a red light, closed railroad crossings or at a traffic jam.
  • the driver is reminded of the operational state of his vehicle and prevented, for example, from leaving the vehicle without thinking.
  • this memory can be an occasion for the driver to switch off his vehicle to save energy.
  • the driver feedback can be generated by the vehicle without the interposition of a separate evaluation device which receives, for example via sensors, conditions of the vehicle or the surroundings of the vehicle. Rather, it is possible to cause the driver feedback directly via the control unit of the vehicle, such as in the manner in which a display or other visual display for signaling an operational state of the vehicle, for example in hybrid vehicles takes place.
  • the figure shows a vehicle with apparatus and method for generating tactile driver feedback.
  • Figure 1 shows a vehicle 1, namely a motor vehicle 2, which is designed as a hybrid vehicle 3 with drive by an internal combustion engine 4 and an electric motor 5, and wherein the internal combustion engine 4 and
  • Electric motor 5 are controlled and switched by a control unit 6 or by a control unit network in their operating states and bring their mechanical power output via a gear 7 and drive shafts 8 on the wheels 9 to drive the vehicle.
  • the vehicle 1 has a passenger compartment 11 for receiving a driver 12 and other passengers, not shown, and / or loads.
  • a driver's seat 13 is provided, which is configured in a conventional arrangement in front of a dashboard 14 and a steering wheel 15.
  • the electric motor 5 or both can be used, wherein the selection takes place depending on the state of charge of batteries, not shown, for the electric motor 5 via the control unit 6.
  • such a selection of the drive can also be effected by the driver 12.
  • unrepresented accelerator pedal attach a torque request to the controller 6, which then converts via the transmission 7 and either the engine 4 or the electric motor 5 or optionally both the torque request in a rotational movement of the wheels 9 and thus the vehicle 1 moves.
  • the usual noise from the engine 4 noise and / or vibration backdrop is not given to the driver 12, which may be in unfavorable situations or in great inattention of the driver 12 confusion about the state of the drive train 10 , in particular on whether the vehicle will respond to a torque request, ie is ready to drive.
  • a signaling element 17 is arranged under the driver's seat 13 as a vehicle device 16, namely a vibration element 18, which communicates with the control device 6 via suitable connecting lines, not shown. The state of the drive train 10 is transmitted to the vehicle device 16.
  • the control unit 6 which is responsible for the control and switching of internal combustion engine 4 and electric motor 5, the operational readiness of the drive train 10, in particular after restart of the electric motor 5 is present, via the not shown suitable electrical connections, the vibrating element 18 under the driver's seat 13th actuated, so that a driver feedback 19 from the vibrating element 18 and the signaling element 17 to the driver 12 via the vehicle device 16, namely the driver's seat 13, is introduced.
  • the driver 12 thus perceives, via his sitting in the driver's seat 13, the driver feedback 19 due to the vibration of the vibration element 18, so that for him the state of the drive train 10 can be seen as ready for operation.
  • the steering wheel 15 via the signaling element 17 or a further signaling element 17 can be used to generate a driver feedback 19 as a further vehicle device 16.
  • driver feedback 19 can be provided to execute the driver feedback 19 periodically, that is to say at essentially the same time intervals, for a specific time, in order to provide the driver 12 with regular feedback about the driver R. 323738 7
  • the driver feedback is formed here as a vibration message 20.
  • This 5 has the advantage that it can be perceived by the driver 12 unconsciously and without purposeful attention. Further, it has the advantage that it can be designed to be similar to, or similar to, the commonly driven motor vehicles equipped with internal combustion engines 4 when operating with internal combustion engine 4. In this respect, there is no learning need for the driver 12 and no settling-in period.
  • the driver feedback 19 may additionally be an acoustic message 21, wherein both the vibration message 20 and the acoustic message 15 21 may alternatively or cumulatively and with other, not shown messages, in particular optical signaling, for example via displays not shown in the dashboard 14 or other suitable facilities can be combined.
