An automatic vehicle braking arrangement includes a vehicle control unit configured to determine whether one or more conditions that must occur to activate an automatic braking function of the vehicle are occurring, to automatically activate the automatic braking function after determining that the one or more conditions are occurring, and to automatically release the automatic braking function after determining that one or more conditions that must occur to release the automatic braking function are occurring. A method for operating such an arrangement is also provided.

A system (e.g., a vehicle control system) includes a brake control unit that is configured to be operably deployed onboard a vehicle. The brake control unit has one or more sensor inputs and one or more control outputs. One of the sensor units is configured to receive a speed signal from a speed sensor of the vehicle; the speed signal is indicative of a vehicle speed detected by the speed sensor. One of the control outputs is configured for connection to a brake system of the vehicle. The brake control unit is configured to generate a vehicle control signal to initiate a vehicle brake operation responsive to the speed indicated by the speed signal going above a designated first speed threshold and the speed signal meeting one or more first designated criteria in addition to the first speed threshold.
