Autonomous braking failure management in pedestrian protection
First Claim
1. A collision avoidance system for a vehicle, the collision avoidance system comprising:
- a video camera configured to detect a presence of a pedestrian;
a distance sensor configured to detect the presence of the pedestrian;
a driver control configured to receive an input from a driver;
a vehicle control system configured to automatically maneuver the vehicle; and
a controller including an electronic processor, the controller communicatively coupled to the video camera, the distance sensor, the driver control, and the vehicle control system, the controller configured toreceive a first signal from the video camera indicative of the presence of the pedestrian,receive a second signal from the distance sensor indicative of the presence of the pedestrian,when the presence of the pedestrian is detected by both the video camera and the distance sensor, determine a course deviation from a current path of travel of the vehicle and activate a timer, wherein the timer is activated after the presence of the pedestrian is detected,when the driver control receives an input from the driver that is above a threshold, reset the timer, andwhen the driver input is below the threshold and the timer expires, apply the course deviation using the vehicle control system.

Abstract
A collision avoidance system and method for a vehicle. The system includes a video camera and a distance sensor. The system includes a driver control, a vehicle control system, and a controller. The controller is communicatively coupled to the video camera, the distance sensor, the driver control, and the vehicle control system. The controller receives a first signal from the video camera indicative of the presence of the pedestrian and receives a second signal from the distance sensor indicative of the presence of the pedestrian. The controller determines a course deviation from a current path of travel of the vehicle and activates a timer. The controller resets the timer when the driver control receives an input from the driver that is above a threshold. When the driver input is below the threshold and the timer expires, the controller applies the course deviation using the vehicle control system.

11. A method of performing collision avoidance for a vehicle, the method comprising:
-
receiving, at a controller, a first signal from a video camera indicative of a presence of a pedestrian, receiving, at the controller, a second signal from a distance sensor indicative of the presence of the pedestrian, when the presence of the pedestrian is detected by both the video camera and the distance sensor, determining, at the controller, a course deviation from a current path of travel of the vehicle and activate a timer, wherein the timer is activated after the presence of the pedestrian is detected by both the video camera and the distance sensor, when a driver control receives an input from the driver that is above a threshold, resetting the timer, and when the driver input is below the threshold and the timer expires, applying the course deviation using a vehicle control system. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A collision avoidance system for a vehicle, the collision avoidance system comprising:
-
a sensor configured to detect a presence of a pedestrian; a driver control configured to receive an input from a driver; a vehicle control system configured to automatically maneuver the vehicle; and a controller including an electronic processor, the controller communicatively coupled to the sensor, the driver control, and the vehicle control system, the controller configured to receive a signal from the sensor indicative of the presence of the pedestrian, determine a probability of collision between the pedestrian and the vehicle; when the probability of collision is greater than a threshold, determine a course deviation from a current path of travel of the vehicle and activate a timer, wherein the timer is activated after determining a probability of collision between the pedestrian and the vehicle, when the driver control receives an input from the driver that is above another threshold, reset the timer, and when the driver input is below the threshold and the timer expires, apply the course deviation using the vehicle control system.
