A method for returning driver control in a vehicle during automatic braking includes the steps of determining a minimum value of accelerator pedal position during the automatic braking, determining a current value of accelerator pedal position, and disengaging the automatic braking, if the current value is greater than the minimum value by at least a predetermined value.

Override of automatic braking in a collision mitigation and/or avoidance system

A method and apparatus is provided for detecting and avoiding an obstacle using a system of a vehicle. The method includes the steps of detecting a distance between the obstacle and the vehicle, generating an action when the distance between the obstacle and the vehicle is less than a threshold, determining whether an override of the system has been initiated, and disabling the action if it is determined that the override has been initiated. The system includes an obstacle detector, an action generator, an override mechanism, and a processor configured to implement the steps of the method set forth above.

Threat assessment state processing for collision warning, mitigation and/or avoidance in ground-based vehicles

A rear obstacle detection and avoidance system for use on a vehicle comprises a rear obstacle detector that is coupled to the vehicle and measures the distance between the vehicle and an obstacle substantially to the vehicle's rear, a speed sensor that determines vehicle speed, an alert generator that notifies an occupant of the vehicle of a rear obstacle, and a processor that is coupled to the rear obstacle detector, the speed sensor, and the alert generator. The processor causes the generation of a first alert when the vehicle's speed is less than a threshold speed and the distance between the vehicle and an obstacle substantially to the vehicle's rear is less than a first distance determined in accordance with a first function of speed vs. distance. Additionally, the processor causes the generation of a second alert when the vehicle's speed is greater than the threshold speed and the distance between the vehicle and an obstacle substantially to the vehicle's rear is less than a second distance determined in accordance with second function of speed vs. distance.
