A method of operating a drive-train (1) of a motor vehicle, which has a drive aggregate (2), a transmission (3) with a hydrodynamic torque converter (4), an engine brake device (6) and a drive output (5). The engine brake device (6) which is activated when the drive-train (1) is operating in an overdrive mode, during a coasting process, before carrying out an overdrive downshift, when the turbine rotational speed (n_tu) of the torque converter (4) is lower than the engine idling rotational speed (n_mot_LL) of the drive aggregate (2). The engine brake device (6) is deactivated at a point in time chosen such that, when the overdrive downshift is carried out, a load change in the drive-train (1) is avoided.

A control device is provided for a motor vehicle having an electronically controllable automatic transmission, an electronic transmission selector lever and an electronic control unit. The control unit, which may be the transmission control unit, has a car wash functional module such that, after activation of the car wash functional module, the following steps are permitted at least once and/or at least for a predefined limited time, in each case without activation of the brake pedal: shutting down of the engine in the transmission selector lever position N; a subsequent restart of the engine in the transmission selector lever position N; and a changeover from the transmission selector lever position N to D. The car wash functional module can be activated or deactivated by the driver at his discretion via a display operator control element.

A computing device detects that an ignition switch of the vehicle was activated, wherein the vehicle includes a navigation device. The computing device requests a destination from the navigation device. The computing device interlocking, an operation of the vehicle based on determining that the destination is not valid.

Methods and systems are provided for generating a predictive tachometer profile at a tachometer of a vehicle. When an inertia phase of a transmission shift event is determined to be in progress, the predictive tachometer profile can be computed based on: a computed shift completion percentage; a difference between the current attained gear speed and the commanded gear speed; and a commanded engine torque that is determined based on the accelerator pedal position and the vehicle speed. The predictive tachometer profile can then be displayed at the tachometer. The predictive tachometer profile accounts for delays in a signal path between an engine speed sensor and the tachometer.

Provided is a steering assist apparatus including: a detector configured to detect an own-vehicle peripheral state of an own-vehicle; a mode selector configured to select any one of a parallel exit-from-parking-space mode and a parking mode as a mode based on the own-vehicle peripheral state detected by the detector; and a steering assist device configured to set a target path to a target position, and assist a steering operation of a driver in such a manner that the own vehicle travels along the target path. The mode selector selects any one the parallel exit-from-parking-space mode and the parking mode based on the own-vehicle peripheral state detected by the detector.
