<p>A component of a motor vehicle, such as the gearbox in an automatic transmission (Fig. 1-15) or the engine (Fig. 16-20) is controlled adaptively by:-… Storing data relating to at least two consecutive timing intervals tset (eg the notional time for the engine speed to vary by two amounts) in store 91 at preset ordinates (eg engine speed (n), torque (P), airflow (Q), possibly in combination);… obtaining 67 actual data corresponding to the stored data but possibly at different ordinates;… interpolating 66 the stored data if necessary;… comparing 73 the actual 131 and interpolated 130 data;… using the result of the comparison to obtain 99 a correction face tork for the stored data at the nearest preset ordinate only; and… storing the correction factor in store 90 for subsequent correction of stored data tset, in which case it also may be interpolated 92. Correction factor K is then updated adaptively. …<??>Embodiments allow smooth gear change, reduced pollution and reduced knocking. …<IMAGE>… </p> |
