US 5,315,516 A · Process and system for generating a signal representative of the transverse movement of a vehicle

Abstract

Signals delta.sub.-- w representing the RPM difference of at least two wheels of at least one axle and signals V representing the vehicle speed are linked through a nonlinear characteristic diagram. Obtained thereby are signals which represent the transverse movements, specifically the transverse acceleration, of the vehicle. This makes it possible to allow for nonlinear effects such as the expansive deflection of the curve inside tires and the compressive deflection of the curve outside tires due to the roll moment backing, particularly through empirically determined parameters. The signal of the stationary transverse acceleration is dynamized by further processing, in a second order filter, of the signal of the stationary transverse acceleration (steering angle is constant) so obtained.

Dependent claims

A method of generating a signal representative of transverse movement of a vehicle, comprising the steps of:

determining respective speeds of rotation of a plurality of wheels, at least two of said wheels associated with an axle of the vehicle;
generating a first signal representing a difference between said speeds of rotation of said at least two wheels;
generating a second signal representing a speed of the vehicle;
generating a third signal representing a static transverse acceleration of the vehicle, utilizing mapped data, dependent on said first and second signals;
and
processing said third signal in a second order filter having an output comprising a fourth signal representing a dynamic transverse acceleration of the vehicle, said fourth signal corresponding to said signal representative of said transverse movement.
