The invention relates to an acceleration sensor having a fastening axis, which is configured to fasten the acceleration sensor to a carrier along the fastening axis by means of a screw, and a sensor element having a plurality of sensor axes. A linear combination of all sensor axes runs parallel to the fastening axis. The invention also relates to a motor vehicle having in each case at least one acceleration sensor which is arranged in each case between a spring leg and a brake disc of a front wheel of the motor vehicle, wherein each acceleration sensor has a sensor element having a plurality of sensor axes. A linear combination of all sensor axes of the acceleration sensor is orthogonal to a horizontal plane of the motor vehicle. In a method for determining a vertical tyre force (Fz) of a wheel of the motor vehicle, at least one acceleration (z̈R) at a wheel of the motor vehicle in the direction of the ground is taken into account in the determination.
