Tilt angle detection device

Abstract

Tilt angle detection device in a vehicle (1) which has a chassis (3) with several vehicle wheels (10, 11, 12, 13) and several vehicle axles (8, 9) spaced apart from each other in a longitudinal direction (x) of the vehicle, each of which is assigned at least one of the vehicle wheels, and a vehicle body (2) supported by the chassis (3), wherein the tilt angle detection device (27) comprises several sensor units (30, 33) by means of which quantities characterizing a tilt of the vehicle body can be detected and sensor signals (a_b, Δ_b; a_RR) characterizing these quantities can be provided, an evaluation unit (35) connected to the sensor units (30, 33) which includes a neural network (44) by means of which a tilt (ΔN) of the vehicle body (2) is generated from the sensor signals (a_b, Δ_b; a_RR) or signals derived therefrom. Inclination signal (S&thgr;') can be determined, a load detection unit (36) by means of which at least one mass distribution value (Vm) characterizing a mass distribution of the vehicle (1) can be determined, and a correction unit (37) by means of which a load-dependent offset (&Dgr;S&thgr;) of the tilt signal can be compensated depending on the at least one mass distribution value (Vm).;
