Abstract
An apparatus (10) for controlling the road speed of a motor vehicle has an accelerator pedal (12), which is biased counter to its actuating direction into an inoperative position and is movable from the inoperative position into a neutral position, from which a further movement of the accelerator pedal (12) counter to the spring bias leads to an increase of the drive torque of the motor vehicle drive. A device for detecting the inoperative position of the accelerator pedal (12) is connected to a braking-force generator (40) and in the inoperative position of the accelerator pedal (12) causes the braking-force generator (40) to make a predetermined braking force available. In order to make the apparatus (10) more comfortable, according to an alternative the braking-force generator (40) builds up the predetermined braking force in a controlled manner when the accelerator pedal (12) attains its inoperative position, and/or reduces the built-up braking force in a controlled manner when the accelerator pedal (12) leaves its inoperative position. According to another alternative, the device for detecting the inoperative position of the accelerator pedal (12), upon a movement of the accel…
