Method for controlling a deceleration arrangement of a motor vehicle
First Claim
1. A method for controlling a deceleration arrangement of a motor vehicle with at least one regenerative braking device, which is designed to decelerate the motor vehicle at a variable braking torque and to generate electrical energy according to the braking torque, wherein a speed of return of an operating element for driving the motor vehicle is detected, wherein a predefined braking torque is exerted by the regenerative braking device when the speed of return and/or a variable correlated therewith exceeds a first predefined threshold value or the speed of return and/or a variable correlated therewith falls below a second predefined threshold value.

Abstract
The invention relates to a method for controlling a deceleration arrangement (10) of a motor vehicle with at least one regenerative braking device (12) which is designed to decelerate the motor vehicle by means of a variable braking torque and to generate electrical energy corresponding to the braking torque. A return speed of an operating element for driving the motor vehicle, in particular an accelerator pedal (22), is detected (S2). A predefined braking torque is exerted (S5) by the regenerative braking device (12) if the return speed and/or a variable correlating thereto exceed(s) or fall(s) below a predefined threshold value.
