According to an aspect, a method includes receiving a passenger request to reserve an elevator car of an elevator system to travel to a targeted destination. At least two different travel options to the targeted destination are determined based on a plurality of elevator car travel plans comprising at least two elevator cars having different travel ranges. The at least two different travel options are output to an interactive display. At least one of the at least two elevator cars is reserved responsive to a user selection of one of the at least two different travel options.

According to an embodiment there is provided a building automation system control apparatus comprising building automation system control logic configured to receive signaling from entities connected to a building automation system and to cause transmission of control signaling to the entities connected to the building automation system, wherein the building automation system control logic comprises elevator control logic as an integral part to directly control an elevator system comprising one or more elevators, the building automation system control logic being configured to take into account signaling received from the entities connected to the building automation system when determining control signaling for the elevator system; and the building automation system control logic being configured to take into account signaling received from the elevator system when determining control signaling for the entities connected to the building automation system.

A group control device according to the present disclosure includes a registration unit, a calculation unit, and a selection unit. The registration unit makes call registration for a boarding floor, a destination floor, and an allocated car when a user makes a hall destination call by a hall destination calling device. The calculation unit calculates an in-car stay time of the user for the hall destination call. The selection unit selects a past hall destination call as an alternative candidate for call registration for a new hall destination call, in a case where the past hall destination call which has already been registered by the registration unit, whose allocated car is different from a car allocated to the new hall destination call, and whose in-car stay time is shorter than the in-car stay time calculated by the calculation unit.

A method of assigning destination call in an elevator group forms chromosomes including genes where each gene is a correlation of a call and an elevator trip, the possible round trips are calculated, each round trip is evaluated for optimization procedure. The calls are assigned to the elevators by the destination call control based on the best chromosome determined.

The present disclosure provides a system and a method for controlling motion of a bank of elevators. The method includes accepting current requests for service by the bank of elevators, accepting a partial trajectory of a motion of a person moving in an environment serviced by the bank of elevators, and obtaining a probability of a future elevator request. The method further includes processing the partial trajectory with a neural network trained to estimate a weighted combination of probability density functions that indicates an arrival time distribution of the person, and generating a set of possible future requests jointly representing the probability of the future elevator request and the arrival time distribution. The method further includes optimizing a schedule of the bank of elevators to serve the current requests and the set of possible future requests, and controlling the bank of elevators according to the schedule.

A method for controlling an elevator where an elevator is allocated for the use of a passenger in a first optimization phase in such a way that a first cost function is minimized, a second optimization phase is performed, in which the route of the allocated elevator is optimized in such a way that a second cost function is minimized.

Each of a plurality of cars includes an in-car notification device configured to receive an announcement command from one of the individual car control devices, to thereby execute an announcement of the name of its own car. When an assignment command is received from a group management device, each of a plurality of individual car control devices causes the car to perform a door opening operation after causing the car to arrive at a floor on which a user is to ride in the car, and outputs the announcement command when it is determined after the door opening operation is finished that an elapsed period of time since the reception of the assignment command is equal to or longer than a period of time required for the user to arrive at an elevator landing after registering a destination floor call on the landing operation panel.

A drive system for driving an electric motor includes a drive control unit and a frequency converter including a speed controller. The drive control unit is configured to: define a speed reference of the electric motor; preset operating parameters of the speed controller to provide a first response time of the speed controller, before a drive of the electric motor is initiated; adjust at least one operating parameter of the speed controller to provide a second response time of the speed controller, after the speed of the electric motor reaches a constant speed, wherein the second response time is slower than the first response time; and readjust the at least one operating parameter of the speed controller to provide the first response time, before a deceleration from the constant speed is initiated. A method is disclosed for controlling the drive system for driving the electric motor.

A method for dispatching an elevator car that includes determining a first duration for each of a plurality of first elevator cars to travel from a current location to a first location, and dispatching at least one of the first elevator cars to the first location when the first duration of the at least one first elevator car is less than a threshold duration. The method includes determining a second duration for an occupant to travel from the first location to a second location, and each of a plurality of second elevator cars to travel from the current location to the second location, when the first duration for the first elevator cars exceeds the threshold duration. The method includes dispatching at least one of the second elevator cars to the second location when the second duration of the at least one second elevator car is less than the threshold duration.

A method for allocating elevators in an elevator system, the elevator system including a group control system responsive to hall calls received from call input devices, and elevator-specific elevator controllers configured to control elevators based on commands issued by the group control system, wherein the method including generating a number of route alternatives based on calls active; calculating, by the elevator controllers, elevator-specific cost terms associated with the route alternatives; transmitting, by the elevator controllers, the cost terms to the group control system; and allocating, by the group control system, the hall calls to the elevators according to the route alternative giving the lowest allocation cost.
