Abstract

Measurements or estimates of yaw rate (psi'), transverse velocity (Vy) and steering angle (delta) are used (1) in conjunction with vehicle-specific constants (Rv, beta) and free-running wheel speeds (vfr2-vfr4) in calculation of reference tolerances (phi 2 - phi 4). First-order filters (2,3) are applied to obtain absolute tolerances (r2-r4) for a final calculation (4) of the speeds to be compared with a reference wheel speed (vr01) in a controller (5). An AND gate (6) activates these computations only when eight specified conditions related to vehicle operation are fulfilled. USE/ADVANTAGE - In antilock braking and wheel-slip control systems, much more precise correction of wheel speed signal is possible even at low traction and steering torques.
