The invention relates to a device and a method for measuring motion quantities for the purpose of recognizing the driving status of a motor vehicle with the aid of a first sensor for measuring a motion quantity along a first direction in space and a second sensor for measuring the motion quantity along a second direction in space, the measuring direction of the first sensor forming an angle with the measuring direction of the second sensor. In this manner, a primary direction and an additional direction can be assigned to the two measuring directions of the sensors. The primary direction coincides with one of the two measuring directions of the sensors or it lies between the two measuring directions of the sensors so that both measuring directions of the sensors have a component along the primary direction. The additional direction is essentially perpendicular to the primary direction and lies in the plane defined by the two measuring directions of the sensors so that at least one of said measuring directions also has a component along the additional direction. The device is configured so that, on the one hand, two essentially redundant values of the motion direction are measured along the primary direction and, on the other, additionally the motion quantity along the additional direction is calculated from the values measured by the first sensor and the values measured by the second sensor.
