Description
Technical Field
The invention relates to a pedal device for an electrically motor-driven motor vehicle.
Background
An electrically motor-operated motor vehicle may include an electric or hybrid vehicle having an electric machine for driving. The electric machine can be operated as an electric motor as well as a generator. The drive torque adjustable on the electric machine for the motor vehicle can be set by means of a driving pedal, similar to that in a vehicle which can be operated with an internal combustion engine. The torque is increased or decreased depending on how far the driver depresses the travel pedal.
In known electric or hybrid vehicles, it is known that the electric machine assumes the function of a generator which feeds back the current drawn from the kinetic energy into the vehicle battery as soon as the driver switches the driving pedal into a position in which the vehicle is decelerated. The process is also referred to as a recovery run. At the same time, a braking torque is generated which can lead to an effective deceleration of the motor vehicle.
In order to decelerate the motor vehicle, the driving pedal is arranged in a deceleration region. In known electric-motor-driven motor vehicles, a neutral region is provided between the acceleration region and the deceleration region, in which neutral region the electric-motor-driven motor vehicle is idling.
A pedal device is known from DE 102011088312 a1, in which a feedback in the form of vibrations can be given to the driver when the neutral range is exceeded.
Disclosure of Invention
It is an object of an exemplary embodiment of the present invention to further develop the pedal device described at the outset in such a way that it can be easily adapted to different users and their needs.
The object is achieved by a pedal arrangement for a motor vehicle which can be operated by an electric motor, having at least one travel pedal for adjusting the acceleration of the motor vehicle by a driver, which travel pedal can be moved along a travel pedal path and can be arranged in an acceleration region of the travel pedal path in which the motor vehicle can be accelerated in motor operation, in a deceleration region of the travel pedal path in which the motor vehicle can be decelerated in generator operation and in a neutral region of the travel pedal path between the acceleration region and the deceleration region, having at least one feedback unit which has at least one feedback mechanism by means of which at least a transition from the acceleration region to the neutral region or from the deceleration region to the neutral region can be fed back to the driver, and having at least one adjusting unit, at least one path length of an acceleration region, a deceleration region and/or a neutral region in the travel pedal path can be adjusted by the adjustment unit.
The path length of the acceleration region, the deceleration region and/or the neutral region in the travel pedal path can be adjusted by the adjustment unit. In this way, for example, the percentage proportion of the path length of the travel pedal in the acceleration region, the deceleration region and/or the neutral region in relation to the overall path length can be set. For example, a neutral region in the path length of the running pedal may be set to 30% to 50%. Correspondingly, the deceleration zone comprises the first 0 to 30% of the path length of the running pedal and the acceleration zone comprises a range from 50% to 100% of the path length of the running pedal.
In principle, it is conceivable that the regulating unit can be operated automatically. In one embodiment of the pedal device, it is provided that the adjusting element comprises at least one actuating element, by means of which the path length of the acceleration region, the deceleration region and/or the neutral region can be adjusted manually.
In this case, the user of the motor vehicle can easily adjust the pedal device to his individual needs. Furthermore, it has proven to be advantageous if the path length of the acceleration region, the deceleration region and/or the neutral region can be adjusted pneumatically, hydraulically, mechanically and/or electronically by means of the actuating element.
If the path length of the acceleration region, deceleration region and/or neutral region can be adjusted pneumatically or hydraulically by the actuating element, pneumatic and/or hydraulic components which are installed in motor vehicles per se can be used.
If the path length of the acceleration region, the deceleration region and/or the neutral region can be adjusted mechanically, the actuating element can be arranged, for example, directly on the driving pedal, for example, when the driving pedal is transferred to the motor vehicle. If the path length of the acceleration region, the deceleration region and/or the neutral region can be adjusted electronically, the actuating element can be arranged at a distance from the driving pedal.
In one embodiment of the pedal device, it has proven advantageous if the pedal device comprises at least one control unit, in which the path length of the acceleration region, the deceleration region and/or the neutral region can be stored or is stored, by means of which the position of the running pedal can be linked to the acceleration region, the deceleration region and/or the neutral region and in which the linking of the position of the running pedal to the acceleration region, the deceleration region and/or the neutral region can be electronically set by means of the operating element.
The position of the running pedal can be detected, for example, by means of at least one sensor element.
In order to indicate the transition from the acceleration region or the deceleration region to the neutral region in a simple and cost-effective manner relative to the driver, it has proven advantageous if the at least one feedback mechanism of the feedback unit comprises at least one optically, acoustically, tactilely and/or tactilely perceptible feedback mechanism, such as a screen, a display, a loudspeaker and/or a vibrating element.
If the feedback mechanism of the feedback unit comprises an optically perceivable feedback mechanism, said feedback mechanism may for example comprise a screen, a panel or a light source. If the feedback mechanism comprises an acoustically perceptible feedback mechanism, for example, a loudspeaker or a signal transmitter mounted in the motor vehicle can be used. If the feedback mechanism comprises a tactile and/or haptic feedback mechanism, said feedback mechanism may for example comprise a vibrating element.
In a further development of the last-mentioned embodiment, it has proven to be advantageous if the tactile and/or haptic feedback means comprise a vibration element which is arranged indirectly or directly on the running pedal and/or on a manually actuable steering mechanism, such as a steering wheel or a joystick.
By the fact that the vibration element can be arranged in the driving pedal and/or in a manually actuatable steering mechanism, such as a steering wheel or a joystick, the transition from the acceleration or deceleration region to the neutral region is shown to the driver in a simple manner.
In a further embodiment of the pedal device, it is provided that the at least one actuating element of the actuating unit and the at least one feedback mechanism of the actuating unit comprise a common component.
For example, it is conceivable for the pedal device to comprise a control unit which communicates with the feedback mechanism via an operating element in the form of a screen, panel and/or display and in this regard can provide the path length stored in the control unit for the acceleration region, deceleration region and/or neutral region, or can adjust its correlation with the position of the driving pedal. In such a case the operating element may comprise a touch screen.
In addition, the embodiment of the running pedal provides that the feedback to the driver of the transition from the acceleration region or from the deceleration region to the neutral region includes a continuous or temporally defined feedback that can be optically, acoustically, tactilely and/or tactilely perceived, in particular an optical or acoustic indication or vibration.
In such a case, the feedback of the transition from the acceleration or deceleration region to the neutral region can be carried out permanently or in a temporally defined manner.
In a further development of the last-mentioned embodiment, it has proven advantageous if the switching mechanism of the actuating element and/or the actuating unit can be used to adjust a time duration during which the temporally defined optically, acoustically, tactually and/or tactilely perceptible feedback takes place.
The duration can thus be predefined by the user of the motor vehicle by means of the operating element. Alternatively or in addition thereto, a switching mechanism can be provided, with which the duration can be adjusted.
Finally, it has proven advantageous if the feedback to the driver of the transition from the acceleration region or from the deceleration region to the neutral region can be switched on and/or off by the driver by means of the operating element and/or the switching mechanism of the control unit.
In such a case, the feedback to the driver that would transition from the acceleration region or from the deceleration region to the neutral region may be discontinued when this proves inappropriate for the driver.
In the neutral range, the motor vehicle can be operated in idle mode.
By providing a control unit, in which the vehicle can be accelerated more strongly, the further the travel pedal is from the neutral range in the acceleration range, for example, can be stored. Correspondingly, the further the travel pedal is from the neutral region in the deceleration region, the greater the deceleration of the motor vehicle.

Detailed Description
Fig. 1 shows a schematic side view of a pedal device for an electrically motor-driven motor vehicle (not explicitly shown in the figures) which is provided with the reference number 2 in its entirety. The pedal device 2 comprises a travel pedal 4 for regulating the acceleration of the motor vehicle by the driver. The running pedal 4 is movable along the running pedal path 6 and can be arranged in an acceleration region 8 of the running pedal path 6, in a deceleration region 10 of the running pedal path 6, in which the motor vehicle can be accelerated in motor operation, and in a neutral region 12 of the running pedal path 6, which is arranged between the acceleration region 8 and the deceleration region 10, in which the motor vehicle can be decelerated in generator operation.
Furthermore, the pedal device 2 comprises a feedback unit 14 having at least one feedback mechanism 16, by means of which at least one transition from the acceleration region 8 to the neutral region 12 or from the deceleration region 10 to the neutral region 12 can be fed back to the driver. Furthermore, the pedal device 2 comprises an adjustment unit 18, by means of which at least one path length of the acceleration region 8, the deceleration region 10 and/or the neutral region 12 in the travel pedal path 6 can be adjusted.
In the embodiment visible in fig. 1, the adjusting element 18 comprises an operating element 20, by means of which the path length of the acceleration region 8, the deceleration region 10 and/or the neutral region 12 can be adjusted manually. In the exemplary embodiment shown in fig. 1, the operating element 20 is formed by an optical feedback mechanism 16, in particular a touch screen.
Furthermore, the pedal device 2 according to the exemplary embodiment of fig. 1 comprises a control unit 22, in which the path length of the acceleration region 8, the deceleration region 10 and/or the neutral region 12 can be stored and can be adjusted by means of an operating element 20, and by means of which the position of the travel pedal 4 can be associated with the acceleration region 8, the deceleration region 10 and/or the neutral region 12 and can be adjusted.
In addition to the optical feedback mechanism 16, the feedback unit 14 also comprises a tactile or haptic feedback mechanism 16 configured as a vibrating element 24. In the embodiment shown in fig. 1, the vibration element 24 and the running board 4 comprise a common component.
Furthermore, the adjustment unit 18, via the operating element 20 in combination with the control unit 22, includes the possibility of adjusting the duration of the oscillation of the oscillating element 24. Furthermore, the vibration element 24 can be switched in and/or out in its entirety by the operating element 20 of the actuating unit 18.
Fig. 2 shows a schematic representation of the torque at the electric machine of the motor vehicle. As can be seen from fig. 2, the braking torque increases with increasing distance between acceleration region 8 and deceleration region 10. Conversely, the acceleration torque in the acceleration region 8 increases with increasing distance from the neutral region 12.
The features of the invention disclosed in the above description, in the claims and in the drawings may be essential for the realization of the invention in its various embodiments both individually and in each arbitrary combination.
