Estimating the term…
The invention relates to a method and a device for detecting the initiation of the driving off process by a driver of a vehicle. In this context, at least one variable (M, N) is determined and the initiation of the driving off process is then inferred from said variable (M, N). The engine torque (M) and/or the engine speed (N) and/or a variable ({dot over (M)}, {dot over (N)}) which is correlated with the at least one variable (M, N) to be evaluated is used as at least one measured variable. The detection of the driving off process can be used, for example, in methods and devices for avoiding unintentional rolling of the vehicle, in particular when making a hill start.

A method for detecting the initiation of the driving off process by a driver of a vehicle, wherein at least the time derivative ({dot over (M)}) of the engine torque (M) and the time derivative ({dot over (N)}) of the engine speed (N) is sensed as a variable ({dot over (M)}, {dot over (N)}) to be evaluated and the initiation of the driving off process is then inferred from said variable ({dot over (M)}, {dot over (N)}), characterized in that the initiation of the driving off process is detected by virtue of the fact that the time derivative ({dot over (M)}) of the engine torque (M) is greater than or equal to a predefinable engine torque change threshold value ({dot over (M)}0) and at the same time the time derivative ({dot over (N)}) of the engine speed (N) is less than or equal to a predefinable negative engine speed change threshold value (−{dot over (N)}0).
