Abstract
A control system for a powertrain of a vehicle includes a set of sensors configured to monitor a set of operating parameters of the vehicle indicative of at least (i) whether a driver of the vehicle is in control of the vehicle, (ii) an intended direction of motion of the vehicle, and (iii) actual motion of the vehicle and a controller configured to, based on the set of operating parameters determine whether the driver of the vehicle is in control of the vehicle and when the driver is determined not to be in control of the vehicle determine whether the actual motion of the vehicle is in the intended direction of motion of the vehicle and when the actual motion of the vehicle is not in the intended direction of motion of the vehicle, control a torque output of the engine to hold the vehicle stationary.
