Abstract: A method of vehicle and operator guidance by pattern recognition begins with collecting data on vehicle and operator patterns through sensors. The collected data is combined and analyzed with a pattern recognition algorithm. The combined and analyzed data is compared with patterns in a pattern database. If data matches a pattern in the pattern database, the pattern can be selected. If the data does not match a pattern in the pattern database, a new pattern can be created and selected. Based on the selected pattern, a determination is made to passively assist the operator, selectively assist the operator or passively and actively assist the operator. The determined action is then implemented.

Abstract: A method for selecting a trajectory for container locking uses at least one twistlock sensor on a machine to sense a location of a twist lock hole on an object. The sensed location is transmitted to a processor to calculate a sensed trajectory for a twistlock to engage the twist lock hole. At least one operator input sensor is used to sense an input from an operator moving the twist lock to engage the twist lock hole. The sensed operator input is transmitted to the processor to calculate an operator trajectory for the twist lock to engage the twist lock hole. The sensed trajectory is compared with the operator trajectory to determine which should be used.
