Abstract
A method and a device for supporting a driver of a motor vehicle in utilizing an automatic engine start-stop system of the vehicle is provided. A method includes predetermining or determining a first limit value tG1 that indicates a time, which, after an engine has been stopped through the start-stop system, has to elapse until an energy saving through the stopping of the engine compared with a continued operation of the engine is obtained. A time currently carried out through the start-stop system is registered, where t0 is a point of time at which the engine is stopped through the start-stop system and t is a time. A visually, haptically, and/or acoustically perceptible information dependent on the tG1 and Δt(t) from which the driver can gather the time with effect from which the engine stop leads to the energy saving is generated and output.
