1. A control unit for at least one vehicle deceleration device of a vehicle, comprising:
an electronics device having a memory unit in which a characteristic curve is stored which specifies a relation between a first input variable specified by a driver by an actuation of a brake actuation element of the vehicle, and a setpoint variable regarding a setpoint vehicle deceleration to be exerted on the vehicle using the at least one vehicle deceleration device, the electronics device is configured to actuate the at least one vehicle deceleration device under consideration of the characteristic curve and the first input variable in such a way that the vehicle is decelerated using the at least one actuated vehicle deceleration device;
wherein the electronics device is further configured to newly specify at least one characteristic curve value of the characteristic curve and to store a correspondingly modified characteristic curve in the memory unit under consideration of:
a second input variable specified by the driver by an actuation of an accelerator of the vehicle; and/or
a current traffic and/or environment situation ascertained using at least one vehicle-installed and/or external: traffic and/or environment detection device; and/or
an ascertained position of the vehicle and a position-specific item of traffic and/or environment information read out or queried using the ascertained position, wherein the electronics device is configured to reduce at least one characteristic curve value of the characteristic curve after a braking operation induced using the at least one actuated vehicle deceleration device, when at least the second input variable specified by the driver during a first time interval after the induced braking operation exceeds a predefined maximum value.
