Method and operator control system for controlling the trailing throttle of automotive drives

An operator control system configured to activate a control of a trailing throttle of an automotive drive, comprising:

• an arrangement for starting from an automatic transmission that has a control equipped with a plurality of shift programs;
• an arrangement for placing the automatic transmission in operative connection with a selector lever operated by a driver;
• an arrangement for selecting a specific one of the plurality of shift programs automatically as a function of an actuation of an accelerator;
• an arrangement for assigning an operating mode to a specific range of a drag torque for a selection of factors influencing the drag torque of the automotive drive and for one of a drivetrain control and a transmission-shift control;
• and
• an arrangement for performing one of individually and in combination after system start-up and a setting of the selector lever in a permanent position for a forward gear D, steps for controlling one of a drivetrain and the automatic transmission in each case according to the drag torque demanded, and a coasting operation wherein:
• the selector lever includes an electronic selector lever and is guided in a gearshift lever gutter, and
• in the permanent position for the forward gear D, by a formation of two opposite bulges adjacent to the gearshift lever gutter, the selector lever is configured to be tipped in a direction of the two opposite bulges such that, in response to the tipping, in each case one of actions x and y is executable for a purpose of activating one of an operating mode with an increased drag torque B, an operating mode with low drag torque C, and an operating mode for a coasting operation S.
