Abstract

Systems and methods for coordinating and controlling vehicles, for example heavy trucks, to follow closely behind each other, or linking, in a convenient, safe manner and thus to save significant amounts of fuel while increasing safety. In an embodiment, on-board controllers in each vehicle interact with vehicular sensors to monitor and control, for example, relative distance, relative acceleration/deceleration, and speed. Additional safety features in at least some embodiments include providing each driver with one or more visual displays of forward and rearward looking cameras. Long-range communications are provided for coordinating vehicles for linking, and for communicating analytics to fleet managers or others.

First claim

What is claimed is:

1 - 45 . (canceled)

46 . A computerized vehicular convoying control system, useful in association with a plurality of vehicles to identify one or more opportunities to form a convoy of a lead vehicle and at least one following vehicle, the control system comprising, on the at least one following vehicle:
a first computerized controller, responsive to remotely-transmitted information regarding the lead vehicle and the at least one following vehicle, and configured to compute a smooth trajectory for the at least one following vehicle as part of the identification of the opportunity to convoy, the information regarding the lead vehicle and the at least one following vehicle being selected from the group consisting of: vehicle location, vehicle destination, vehicle load, vehicle type, and trailer type; a first inter-vehicular transceiver configured to enable communications between the first computerized controller and a second computerized controller on the lead vehicle; a first vehicular separation sensor configured to detect a distance between the lead vehicle and the at least one following vehicle, and further configured to detect a relative speed between the lead vehicle and the at least one following vehicle, and to provide such distance and relative speed to the first computerized controller; and a first user interface configured to receive an input from the first computerized controller and to provide vehicular data to a driver.

47 . The convoying control system of claim 46 further comprising:
a first braking actuation sensor configured to measure brake actuation and to provide such brake actuation measurements to the first computerized controller;
a first supplemental braking actuator responsive to inputs from the first computerized controller to vary braking of the at least one following vehicle;
a first acceleration actuation sensor for measuring acceleration actuation and providing such measured acceleration to the first computerized controller; and
a first supplemental acceleration actuator responsive to the first computerized controller to vary acceleration of the at least one following vehicle.

48 . The convoying control system of claim 46 , further comprising:
a long-range vehicular transceiver configured to communicate between a central server and the first computerized controller.

49 . The convoying control system of claim 46 , further comprising:
a global positioning system (GPS) receiver providing positioning information to the first computerized controller.

50 . The convoying control system of claim 46 , additionally comprising, on the lead vehicle:
a second computerized controller that is responsive to remotely-transmitted information regarding the lead vehicle and the at least one following vehicle, and configured to compute a smooth trajectory for the lead vehicle as part of the identification of the opportunity to convoy, the information regarding the lead vehicle and the at least one following vehicle being selected from the group consisting of: vehicle location, vehicle destination, vehicle load, vehicle type, and trailer type; a second long-range vehicular transceiver configured to communicate between a central server and the second computerized controller; a second user interface configured to receive an input from the second computerized controller and to provide vehicular data to a driver; a second inter-vehicular transceiver configured to enable communications between the second computerized controller and the first computerized controller; and a forward-facing camera configured to substantially capture a substantially frontal image as viewed from the lead vehicle and to provide such frontal image to the second computerized controller.

51 . The convoying control system of claim 50 , wherein
the substantially frontal image is provided to the first computerized controller via the first and second inter-vehicular transceivers.

52 . The convoying control system of claim 46 , wherein
the second inter-vehicular transceiver is coupled to, and further configured to operate, a rear brake light of the lead vehicle independently of the lead vehicle's braking system as a transmitter of vehicular control signals from the lead vehicle to the at least one following vehicle.

53 . A computerized vehicular convoying control system, useful in association with a lead vehicle and at least one follower vehicle to implement a convoy, the control system comprising, on the at least one follower vehicle:
a first computerized controller, responsive to remotely-transmitted information regarding the lead vehicle and the at least one follower vehicle, and configured to monitor and control acceleration and deceleration of the at least one follower vehicle, thereby maintaining a safe vehicular spacing between the lead vehicle and the at least one follower vehicle while moving, the information regarding the lead vehicle and the at least one follower vehicle being selected from the group consisting of: vehicle location, vehicle destination, vehicle load, vehicle type, and trailer type; a first user interface configured to receive an input from the lead computerized controller and to provide vehicular data to a driver; a first inter-vehicular transceiver configured to communicate between the first computerized controller and a second computerized controller on the lead vehicle; a vehicular separation sensor configured to detect a distance between the lead vehicle and the at least one follower vehicle, and further configured to detect a relative speed between the lead vehicle and the at least one follower vehicle, and to provide such distance and relative speed to the first computerized controller.

54 . The convoying control system of claim 53 , further comprising:
a first braking actuation sensor configured to measure brake actuation and to provide such brake actuation measurements to the first computerized controller; a first supplemental braking actuator responsive to inputs from the first computerized controller to vary braking of the at least one follower vehicle; a first acceleration actuation sensor for measuring acceleration actuation and providing such measured acceleration to the first computerized controller; a first supplemental acceleration actuator responsive to the first computerized controller to vary acceleration of the at least one follower vehicle.

55 . The convoying control system of claim 53 , wherein
the second computerized controller is responsive to remotely-transmitted information regarding the lead vehicle and the at least one follower vehicle, and configured to monitor acceleration and deceleration of the at least one follower vehicle, thereby maintaining a safe vehicular spacing between the lead vehicle and the at least one follower vehicle while moving, the information regarding the lead vehicle and the at least one follower vehicle being selected from the group consisting of: vehicle location, vehicle destination, vehicle load, vehicle type, and trailer type; the system further comprising, on the lead vehicle: a second user interface configured to receive an input from the second computerized controller and to provide vehicular data to a driver; and a second inter-vehicular transceiver configured to communicate between the second computerized controller and the first computerized controller.

56 . The convoying control system of claim 53 , additionally comprising:
a forward-facing camera configured to substantially capture a substantially frontal image as viewed from the lead vehicle and to provide such frontal image to the second computerized controller; and wherein the s
