1. A vehicle configured to perform the steps of:
- determining a time to a potential collision threat identified by using an autonomous emergency braking system of the vehicle, wherein the autonomous emergency braking system of the vehicle comprises pre-defined control phases the pre-defined control phases comprising a first alert phase, a second warning brake phase, and a third full brake phase, and wherein a current one of the control phases depends on the determined time to collision; and
sending the determined time to collision to one or more following vehicles,wherein the determined time to collision is based on a relative speed between the potential collision threat and the lead vehicle or on a distance between the potential collision threat and the lead vehicle.

Abstract
A vehicle is configured to perform the steps of: obtaining an indicator of a potential collision threat identified by an autonomous emergency braking system of the vehicle, wherein the autonomous emergency braking system of the vehicle comprises pre-defined control phases, and wherein the indicator at least partly determines a current control phase of the autonomous emergency braking system; and sending the obtained indicator to one or more following vehicles.

2. A method of controlling inter-vehicle gap(s) between a lead vehicle and one or more following vehicles, wherein the method comprises the steps of:
-
determining a time to a potential collision threat identified by an autonomous emergency braking system of the lead vehicle, wherein the autonomous emergency braking system of the lead vehicle comprises pre-defined control phases, the pre-defined control phases comprising a first alert phase, a second warning brake phase, and a third full brake phase, and wherein a current one of the control phases depends on the determined time to collision; sending the determined time to collision to the one or more following vehicles; receiving, in the one or more following vehicles, the determined time to collision; obtaining, in the one or more following vehicles, a reading from one or more on-board sensors that measure an actual gap to a vehicle ahead, and automatically adjusting inter-vehicle gap(s) based on the received determined time to collision or the obtained reading, wherein the received determined time to collision overrides the obtained reading when the received determined time to collision indicates a greater deceleration than the obtained reading, and wherein the obtained reading overrides the received determined time to collision when the obtained reading indicates a greater deceleration than the received time to collision. - View Dependent Claims (3, 4, 5)

6. A method of controlling inter-vehicle gap(s) between a lead vehicle and one or more following vehicles, wherein the method comprises the steps of:
-
receiving, in the one or more following vehicles, an indicator of a potential collision threat identified by an autonomous emergency braking system of the lead vehicle, wherein the autonomous emergency braking system of the lead vehicle comprises pre-defined control phases, the pre-defined control phases comprising a first alert phase, a second warning brake phase, and a third full brake phase, wherein a current one of the control phases depends on the determined time to collision; obtaining, in the one or more following vehicles, a reading from one or more on-board sensors that measure an actual gap to a vehicle ahead; and automatically adjusting the inter-vehicle gap(s) based on the determined time to collision or the obtained reading, wherein the received determined time to collision overrides the obtained reading when the received determined time to collision indicates a greater deceleration than the obtained reading, and wherein the obtained reading overrides the received determined time to collision when the obtained reading indicates a greater deceleration than the received time to collision. - View Dependent Claims (7)
