Problems solved by technology

[0005] However, this approach has the problem that, in the event of a damaged bonnet sensor, the vehicle may stall in a so-called ready-to-drive mode (Fahrbereitschaftsmodus) or in an electric mode (in which the internal combustion engine has not yet been activated). start), because, in this case, the start of the internal combustion engine is not possible

Abstract

The invention relates to a method and a device (8) for operating a hybrid vehicle (1), wherein the combustion engine (2) of the hybrid vehicle is automatically started if the hybrid vehicle (1) is in a mode ready for driving and an opening of an engine cover (4) of the hybrid vehicle is detected.

Description

technical field [0001] The invention relates to a method and a device for operating a hybrid vehicle (Hybridfahrzeug) for warning of potential hazards (potentiellen ), in particular the danger posed by an unrecognized operating readiness or driving readiness of the hybrid vehicle. Background technique [0002] Modern hybrid vehicles usually have a start / stop device (Start / Stop-Einrichtung), by which the engine of the hybrid vehicle is stopped as soon as the hybrid vehicle stops longer than a predetermined time interval (eg 1 second). stop in order to save fuel. As soon as the driver subsequently actuates the accelerator pedal of the hybrid vehicle, actuates the clutch or engages a gear, the engine is automatically started again in order to continue driving the hybrid vehicle. Furthermore, in modern hybrid vehicles with internal combustion engine (Verbrennungsmotor) and electric motor (Elektromotor), as a rule, under certain preconditions, in particular when the hybrid veh...
