A method for operating a parking lock system () with a parking interlock gear () is provided. The parking lock system () also includes a parking pawl () insertable with an insertion section () in one of recesses () of the parking interlock gear () in order to interlock the parking interlock gear (), a parking lock actuator () for the parking pawl (), and a parking lock sensor () for detecting an absolute rotation angle position of the parking interlock gear (). The method includes detecting an absolute rotation angle position of the parking interlock gear () and comparing the detected absolute rotation angle position with a reference rotation angle position. When the particular absolute rotation angle position is situated behind the reference rotation angle position as viewed in the particular direction of rotation of the parking interlock gear (), a rattling process of the parking pawl () is detected.

Method and control unit for operating a parking lock system

A method for operating a motor vehicle. To determine a total operating strategy, predictive basic data describing the operation of the motor vehicle for a known route is determined from input data comprising route data. The operating strategies of the motor vehicle are evaluated based on the predictive basic data in order to determine the total operating strategy. The motor vehicle is then operated according to the total operating strategy. To determine the basic data, a performance profile is determined based on the total required performance of the vehicle throughout the route. The route is divided into route sections, each assigned characterizing performance information. Successive route sections are combined into a common segment when at least one similarity criterion is satisfied comparing the performance information of the route sections. Thereafter, the segments are provided with this assigned total performance information associated with the total performance information.
