Abstract
A lane change by a motor vehicle is detected in a first variant, such that a lateral-acceleration variable representing the lateral acceleration of the vehicle and/or a yaw variable representing the yaw velocity is ascertained; the change, as a function of time, of the lateral-acceleration variable and/or of the yaw variable is formed; and a lane change is detected when the change as a function of time exceeds a specifiable threshold value. A second variant provides that speed variables are determined which represent the rotations of at least two wheels; a velocity variable is ascertained representing the longitudinal vehicle velocity; the difference is determined between the speed variable of the fastest rear wheel and the velocity variable; and a curve and/or a lane change is detected when a specifiably large difference exists for a time duration of specifiable length.
