Abstract
(DE)
Es wird ein Verfahren zum Verändern einer Kennlinie eines Gaspedals eines Kraftfahrzeugs vorgeschlagen, wobei das Verfahren folgende Schritte umfasst: Feststellen, dass ein Bremskraftverstärker des Kraftfahrzeugs eine Fehlfunktion aufweist, insbesondere dass ein Bremskraftverstärker des Kraftfahrzeugs nicht funktioniert; und wenn eine Fehlfunktion des Bremskraftverstärkers festgestellt wird, Verändern der Kennlinie des Gaspedals derart, dass bei einem Nicht-Betätigen des Gaspedals und einem Nicht-Betätigen eines Bremspedals des Kraftfahrzeugs das Kraftfahrzeug verzögert wird.
(EN)
A method for changing a characteristic curve of an accelerator pedal of a motor vehicle is proposed, wherein the method comprises the following steps: determining that a brake booster of the motor vehicle has a malfunction, in particular that a brake booster of the motor vehicle is not functioning; and if a malfunction of the brake booster is detected, changing the characteristic curve of the accelerator pedal in such a way that when the accelerator pedal is not activated and a brake pedal of the motor vehicle is not activated, the motor vehicle is decelerated.
