Problems solved by technology

For example, starting from a certain position of the accelerator pedal, the actuator can selectively resist further depression of the accelerator pedal in order to signal to the driver, for example, that a stronger depression of the accelerator pedal could lead to a disproportionate increase in fuel consumption.

Embodiment Construction

[0032] figure 1 A cross-sectional view of a vehicle 1 with a tactile accelerator pedal 11 is shown. By depressing said pedal, the driver seated on the seat 5 causes the engine 17 of the vehicle 1 to accelerate the vehicle through the cable drive 15 or a line (not shown) connected to the engine control device. For this purpose, the driver must depress the accelerator pedal 11 in the direction of the arrow 7 , whereby the accelerator pedal 11 can be displaced from the rest position along the displacement range to a position of maximum actuation. In this case, position sensor 21 can determine the current position or current position of accelerator pedal 11 . The spring 19 bounces the drive pedal to the rest position against the operating direction 7 .

[0033] The accelerator pedal 11 is configured as a tactile accelerator pedal. Here, the accelerator pedal 11 has an actuator 13 , by means of which the accelerator pedal 11 is moved in a desired direction opposite to the actuat...

Abstract

A method and a control device for controlling a haptic acceleration pedal in a motor vehicle includes determining a foreseeable signal position in which a haptically perceivable signal is foreseeably to be generated by the acceleration pedal at a future time. The signal position is configured to be located between a rest position and a maximally actuated position within the shifting range of the pedal. While the pedal is located in a current position between the rest position and the foreseeable position, an actuator that is configured to generate a haptically perceivable signal on the acceleration pedal is arranged in such manner that the actuator is in operational connection with the acceleration pedal when the acceleration pedal has reached the foreseeable position. The configuration results in a prompt generation of a haptically perceivable signal and a reduced energy consumption for the actuator.

Description

technical field [0001] The invention relates to a method and a control device for controlling a haptic pedal in a motor vehicle. The invention also relates to a computer program product which, when executed on a programmable control device, is to carry out the method according to the invention, and a computer-readable medium on which the said computer program product. Background technique [0002] In contemporary motor vehicles, a large amount of information is available to support the driver when driving the vehicle. For example, it may be very useful to signal a certain driving state to the driver or to request the driver to take certain measures in order to be able to increase driving safety or driver comfort or to be able to save fuel. The feedback can be provided in different ways, eg optically or acoustically. [0003] In contemporary motor vehicles, the possibility of tactile feedback to the driver via the accelerator pedal of the vehicle is additionally also possi...
