Method for the adaptive control of a driver operation-dependent actual vehicle deceleration

A method for the adaptive control of a driver operation-dependent actual vehicle deceleration (ZIst) in a commercial vehicle, the method comprising:

• determining an operating variable that indicates a displacement of a brake pedal of a brake valve demanded by the driver as well as an assistance deceleration demand;
• providing a mass-dependent feeling curve that associates a driver's deceleration demand with the operating variable;
• adapting the mass-dependent feeling curve if there is no assistance deceleration demand so that the determined operating variable is associated with an actually prevailing actual vehicle deceleration and at least one scaling factor is determined that adapts the driver's deceleration demand which results from the mass-dependent feeling curve for the determined operating variable to the determined actual vehicle deceleration, wherein, for this purpose, an adaptation feeling curve is formed that results from the mass-dependent feeling curve adapted with the scaling factor so that the adaptation feeling curve associates an adapted driver's deceleration demand with the operating variable;
• specifying a target vehicle deceleration depending on a driver operation-dependent driver's deceleration demand determined from the corresponding feeling curve and the assistance deceleration demand if there is an assistance deceleration demand;
• and
• actuating a brake pressure corresponding to the target vehicle deceleration for adaptively adjusted, driver operation-dependent control of the actual vehicle deceleration.
