Assembly and method for monitoring the driving condition of a vehicle
First Claim
1. A system for monitoring a driving condition of a vehicle, comprising:
- an arrangement for generating a steering angle signal;
an arrangement for generating a transverse acceleration signal;
low-pass filters configured to receive the steering angle signal and the transverse acceleration signal which are each routed to the low-pass filters, and to output a filtered steering angle signal and a filtered transverse acceleration signal;
an arrangement for generating a first absolute value of a difference between the steering angle signal and the filtered steering angle signal;
an arrangement for generating a second absolute value of a difference between the transverse acceleration signal and the filtered transverse acceleration signal;
an arrangement for performing a first comparison of the first absolute value to a maximum steering angle signal; and
an arrangement for performing a second comparison of the second absolute value to a maximum transverse acceleration signal;
wherein a variable describing the driving condition of the vehicle is derived from the first and second comparisons.

Abstract
The present invention relates to an arrangement for monitoring the driving condition of a vehicle, having means for generating a steering angle signal (Lw) and means for generating a transverse acceleration signal (ay), means being provided for comparing a signal derived from the steering angle signal Lw to a maximum steering angle signal, means being provided for comparing a signal derived from the transverse acceleration signal (ay) to a maximum transverse acceleration signal, and a variable (F) that describes the driving condition of the vehicle being derivable from the comparison. The present invention also relates to a method of monitoring the driving condition of a vehicle.
