Abstract

A vehicle system for a commercial vehicle comprises a first forward-looking camera, a service braking controller; and a driver assistance controller communicating with the first forward looking camera and the service braking controller. The driver assistance controller identifies a pedestrian as a target within the field of view of the first forward looking camera, determines a distance to the pedestrian is less than or equal to a predetermined distance, transmits a signal to the service braking controller to request deceleration of the vehicle in response to the distance to the pedestrian being less than or equal to the predetermined distance. The driver assistance controller maintains the signal to the service braking controller until the pedestrian is no longer identified as a target.

First claim

What is claimed is:

1 . A vehicle system for a commercial vehicle comprising:
a first forward looking camera; a service braking controller; and a driver assistance controller communicating with the first forward looking camera and the service braking controller; wherein the driver assistance controller
identifies a pedestrian as a target within the field of view of the first forward looking camera;
determines a distance to the pedestrian is less than or equal to a predetermined distance;
transmits a signal to the service braking controller to request deceleration of the vehicle in response to the distance to the pedestrian being less than or equal to the predetermined distance; and
maintains the signal to the service braking controller until the pedestrian is no longer identified as a target.

2 . The vehicle system as in claim 1 , further comprising a parking brake controller in communication with the driver assistance controller, wherein the driver assistance controller transmits a signal to the parking brake controller to park the vehicle in response to the pedestrian remaining a target.

3 . The vehicle system as in claim 2 , wherein a driver of the vehicle is able to override the signal to the parking brake controller.

4 . The vehicle system as in claim 1 , wherein the pedestrian is no longer identified as a target occurs when the pedestrian is detected at a distance greater than the predetermined distance.

5 . The vehicle system as in claim 1 , wherein the driver assistance controller determines that the pedestrian remains a target in response to the pedestrian no longer being detected in a field of view of the first forward camera and not detected at a distance greater than the predetermined distance and thereby continues to transmit the signal requesting deceleration

6 . The system as in claim 1 , wherein the driver assistance controller and the service brake controller are a single controller.

7 . The system as in claim 1 , further comprising a second forward looking camera mounted at a location on the vehicle separate from the first forward looking camera, wherein the pedestrian is no longer a target occurs when the second forward looking camera detects the pedestrian as a distance greater than the predetermined distance.

8 . A method for controlling a commercial vehicle comprising:
detecting a pedestrian with at least one forward camera; determining a distance to the pedestrian is less than or equal to a predetermined distance; and transmitting a signal requesting deceleration of the vehicle as long as the pedestrian is detected less than the predetermined distance.

9 . The method as in claim 8 , further comprising maintaining the signal requesting deceleration of the vehicle until the pedestrian is detected at greater than the predetermined distance.

10 . The method as in claim 8 , further comprising determining that the pedestrian remains less than a predetermined distance in response to the pedestrian no longer being detected by the at least one forward camera and continuing to transmit the signal requesting deceleration.

11 . The method as in claim 8 further comprising: transmitting a signal to engage a parking brake of the commercial vehicle until the pedestrian has been detected at greater than the predetermined distance.

12 . The method as in claim 10 , further comprising: overriding the signal to engage the parking brake through an action of the driver of the commercial vehicle.

13 . The method as in claim 11 further comprising:
detecting the pedestrian has moved to greater than the predetermined distance; and
transmitting a signal to release the parking brake of the commercial vehicle.
