Method for actuating the cruise control function in a vehicle equipped with hybrid driving, especially an industrial or commercial vehicle
First Claim
1. Method for actuating the cruise control function in a vehicle equipped with hybrid driving, especially an industrial or commercial vehicle, said hybrid driving comprising at least a primary driving and an electric driving, the method comprising the steps of:
- cyclic check of the possibility of activation of said cruise control function, wherein said cyclic check of the possibility of activation of the cruise control function comprises;
check if the vehicle'"'"'s speed exceeds a speed threshold value (VS);
check if the vehicle is moving forward;
if positiveactivation of said electric driving of the type “
electric cruise-control”
(ElCC), and deactivation of said primary driving, if a cyclic check of the conditions of activation of the electric driving is positive, wherein said cyclic check of the activation conditions of the electric driving comprises;
if a road slope is lower than a slope threshold value (Pmax);
if a target speed (Vset) set for the activation of the cruise control function is lower than a speed threshold value (Vmax);
if the state of charge (SOC) of the driving battery of said electric driving is higher than a state of charge threshold value (SOCs);
if an instant power required to said electric driving is lower than a power limit value PLIMIT-Mot deliverable by said electric drivingwherein the state of charge threshold value (SOCs) and one or more values of said slope threshold values (Pmax), speed threshold value (Vmax), deliverable power limit value (PLIMIT-Mot), are variable within respective tolerated percentage variations around the respective values;
otherwiseactivation of said primary driving of the type “
engine cruise-cruise control”
(EnCC), and deactivation of said electric driving;
wherein when said cruise control function is actuated, said vehicle is configured to transition between “
electric cruise-control”
(ElCC) and “
engine cruise-cruise control”
(EnCC) without combining “
electric cruise-control”
(ElCC) and “
engine cruise-cruise control”
(EnCC).

Abstract
The present invention describes a method for actuating the cruise control function in a vehicle equipped with hybrid driving, comprising at least a primary driving and an electric driving. The method comprises the steps of: —cyclic check of the possibility of activation of the cruise control function; if positive—activation of the electric driving of the type “electric cruise-control” (ElCC), and deactivation of the primary driving, if a cyclic check of the conditions of activation of the electric driving is positive; otherwise—activation of the primary driving of the type “engine cruise-cruise control” (EnCC), and deactivation of the electric driving.
