Abstract: A device for generating an additional reset force on the gas pedal for motor vehicles, wherein a position change of the gas pedal relative to the initial position thereof, induced by a corresponding actuating force, against a reset force leads to an increase in the motive power of the engine and, when there is a decrease in the actuating force, a reset force moves the gas pedal back in the direction of the initial position thereof, and wherein an actuator is provided, which applies an additional reset force that acts in the reset direction of the gas pedal, and wherein the motor vehicle has a unit for determining the shifting point of a manually shifted transmission. Moreover, the invention relates to a method for operating the device according to the invention.

Abstract: Disclosed is a method for controlling a regenerative brake system with a number of friction brakes (F) and an electro-regenerative brake (R), whose total deceleration is composed of deceleration components of the brakes, and the actual deceleration components are desired to correspond to the nominal deceleration components as exactly as possible. A control unit is used to change the ratio of the nominal deceleration components of a number of brakes (R, F) relative to each other by determining a correction value (k1, k2) for a number of the brakes based on the quantities of efficiency w of a number of brakes representing the ratio between the actual deceleration (aactual) and the nominal deceleration (anominal), which correction value is applied to the nominal deceleration (anominal) of these brakes.
