Patent DE-4123053-A1 (DE)
Inventor: CAO CHI-THUAN DR ING
IPC: G05D1/08
Filed: 1991-07-12
Abstract: Parameters of motion of a vehicle, for example lateral velocity Vy, yaw velocity  omega , floating angle  beta , slip angles av, ah and lateral forces Fy, are determined by the parameters for lateral acceleration ayh, ayv and steering angle  delta v,  delta h of the two codes.
