METHOD AND MODULE FOR DETERMINING AT LEAST ONE REFERENCE VALUE Russian patent published in 2016 - IPC B60K31/00 B60W10/06 B60W10/11 B60W30/14 B60W50/06 

FIELD: data processing; transportation.

SUBSTANCE: to determine a reference value which indicates how a vehicle's speed (V) is to be influenced, following steps are carried out: making a first prediction V_pred_T_new__ret and a second prediction V_pred_T_new__acc of speed along a horizon, said first prediction based on an engine torque T_ret which retards vehicle as compared with a conventional cruise control, and said second prediction based on an engine torque T_acc which accelerates vehicle as compared with a conventional cruise control; comparison of said respective first prediction V_pred_T_new__ret and second prediction V_pred_T_new__acc with lower limit value v_min and/or upper limit value v_max, which delineate a range within which vehicle's speed should be, with an offset V_offset added to said lower and/or upper limit values v_min and v_max, if vehicle is in a route segment which comprises a steep hill; determining at least one reference value based on at least one of said respective comparisons and said first prediction V_pred_T_new__ret and second prediction V_pred_T_new__acc of speed along horizon.

EFFECT: improved cruise control of vehicle, when its speed should be predicted by logic automatic circuit to maintain constant speed and simultaneously should be controlled by a controller, in particular, to avoid unnecessary fuel injection into engine due to unstable control signal in engine control system.
