Abstract

A system for calculating a desired time of arrival to a target destination for a vehicle includes a device mountable to a first vehicle. The device includes a transmitter, a receiver, and a logic unit configured to receive signals for determining a current position and a current vehicle speed of the first vehicle, the logic unit being further configured to determine an estimated time of arrival at a target destination for the first vehicle based on predetermined route information, the current position of the first vehicle and the target destination of the first vehicle. The device is configured to transmit the estimated time of arrival at the target destination for the first vehicle, receive, from a second vehicle, an estimated time of arrival at the target destination for the second vehicle, calculate a desired estimated time of arrival at the target destination for the first vehicle based on the received estimated time of arrival at the target destination for the second vehicle, and calculate a desired vehicle speed for the first vehicle for achieving the desired estimated time of arrival at the target destination for the first vehicle.

First claim

1 . A system for calculating a desired time of arrival to a target destination of a working site for a working machine, comprising a device mountable to a first vehicle being a working machine, the device comprises:
a transmitter; a receiver; and a logic unit configured to receive signals for determining a current position and a current vehicle speed of the first vehicle, the logic unit being further configured to determine an estimated time of arrival at a target destination for the first vehicle based on predetermined route information, the current position of the first vehicle and the target destination of the first vehicle; characterized in that the device is configured to: transmit the estimated time of arrival at the target destination for the first vehicle; receive, from a second vehicle being a working machine, an estimated time of arrival at the target destination for the second vehicle; calculate a desired estimated time of arrival at the target destination for the first vehicle based on the received estimated time of arrival at the target destination for the second vehicle; and calculate a desired vehicle speed for the first vehicle for achieving the desired estimated time of arrival at the target destination for the first vehicle.

2 . The system according to claim 1 , wherein the device is further configured to:
receive an estimated time of arrival at the target destination for a third vehicle being a working machine; calculate a desired estimated time of arrival at the target destination for the first vehicle based on the received estimated time of arrival at the target destination for the third vehicle; and calculate a desired vehicle speed for the first vehicle for achieving the desired estimated time of arrival at the target destination for the first vehicle only if the estimated time of arrival at the target destination for the third vehicle 1 s later than the estimated time of arrival at the target destination for the second vehicle.

3 . The system according to claim 1 , wherein the device is further configured to:
receive an estimated time of arrival at a second target destination for a third vehicle being a working machine; and calculate a desired estimated time of arrival at the second target destination for the first vehicle based on the received estimated time of arrival at the second target destination for the third vehicle only lithe second target destination is the same target destination as the target destination.

4 . The system according to claim 1 , wherein the target destination is a first target destination wherein the device further configured to:
determine an estimated time of arrival at a second target destination for the first vehicle, and select that a next desired target destination for the first vehicle is the first target destination if the determined estimated time of arrival at the first target destination is earlier in time than the determined estimated time of arrival at the second target destination.

5 . The system according to claim 1 , wherein the device is further configured to:
receive signals, from eight sensors of the vehicle, indicative of a current weight of a load on a platform of the vehicle; and select that a next desired target destination for the first vehicle is a second target destination if the weight of the load on the platform of the first vehicle is above a predetermined weight value.

6 . The system according to claim 1 , wherein the device is further configured to:
determine an estimated tune of arrival at a second target destination for the first vehicle; and select that a desired target destination for the first vehicle is the second target destination if a time difference between the estimated time of arrival at a first target destination for the first vehicle and the estimated time of arrival at the first target destination for the second vehicle is below a predetermined time period.

7 . The system according to claim 1 , wherein the target destination is selected based on the route information and the current position.

8 . The system according to claim 1 , wherein the device is further configured to:
receive signals indicative of a weight of a load on a platform of the respective first and the second vehicle, and calculate a desired estimated time of arrival at the target destination for the first vehicle based on the received estimated time of arrival at the target destination for the second vehicle and a weight ratio between the weight of the load on the platform of the first vehicle and the weight of the load on the platform of the second vehicle.

9 . The system according to claim 1 , wherein the device is further configured to:
receive a signal indicative of a current vehicle speed of the first vehicle; receive a signal indicative of a current vehicle speed of the second vehicle; and calculate a desired estimated time of arrival at the target destination for the first vehicle based on the received estimated time of arrival at the target destination for the second vehicle and a vehicle speed ratio between the vehicle speed of the first vehicle and the vehicle speed of the second vehicle.

10 . The system according to claim 1 , wherein the device is further configured to:
transmit a signal to a display unit arranged within a compartment of the first vehicle wherein the signal is indicative of the calculated vehicle speed of the first vehicle.

11 . The system according to claim 1 , wherein the device is further configured to:
transmit a signal to a driveline of the first vehicle wherein the signal is indicative of the calculated vehicle speed of the first vehicle for controlling the speed of the driveline of the first vehicle.

12 . The system according to claim 1 , wherein the calculated vehicle speed of the first vehicle is based on the estimated time of arrival received from the second vehicle and a predetermined time period.

13 . The system according to claim 12 , wherein the predetermined time period is a part of the time period the second vehicle is expected to be stationary at the target destination.

14 . The system according to claim 1 , wherein the device is further configured to:
receive a signal from the target destination, the signal being indicative of an estimated duration of stay for the second vehicle at the target destination.

15 . The system according to claim 1 , wherein the signals received by the logic unit for determining a current position of the first vehicle are provided from a global positioning unit.

16 . The system according to claim 1 , wherein the signals received by the logic unit for determining a current vehicle speed of the first vehicle are provided from a global positioning unit or a speedometer.

17 . A system for calculating a desired time of arrival to a target destination of a working site for a working machine, comprising a first and a second device mountable to a respective first and second vehicle being working machines, each of the first and the second devices comprising:
a transmitter; a receiver; and a logic unit configured to receive signals for determining a current position and a current vehicle speed for the respective first and the second vehicle, the logic unit being further configured to determine an estimated time of arrival at a target destination based on predetermined route information, the current position and the target destination for the respective first and second vehicles, wherein the second device is configured to transmit the estimated time of arrival at the target destination for the second
