The transverse acceleration sensor supplies information about the transverse accelerations occurring in the vehicle to the PSM control module. Together with the information from the steering-angle sensor and the rate-of-turn sensor, the current handling behaviour with respect to its transverse dynamics is calculated. The sensor element is a damped spring-and-mass system.

Its deflection is detected magnetically using a linear Hall element. The deflection is a direct measure of the occurring transverse accelerations.
