Automated vehicle control system with multiple brake-pedal selected disengagement modes
View Patent ↗A control system with multiple brake-pedal selected disengagement-modes for an automated vehicle includes a brake-pedal and a controller. The brake-pedal is used to detect a plurality of pedal-action-classifications based on one of pedal-force, depression-duration, and a combination of pedal-force and depression-duration. The controller is in communication with the brake-pedal. The controller operates the system into a first-mode in response to the brake-pedal being operated in accordance with a first-action-classification, and into a second-mode in response to the brake-pedal being operated in accordance with a second-action-classification different from the first-action-classification.
1. A control system with multiple brake-pedal selected disengagement-modes for an automated vehicle, said system comprising:
a brake-pedal operated by a human-operator of a host-vehicle by pressing on the brake-pedal to indicate one of a plurality of disengagement-modes, said brake-pedal used to detect a plurality of pedal-action-classifications, each of the plurality of pedal-action-classifications corresponding to one of the plurality of disengagement-modes and based on one of pedal-force, depression-duration, and a combination of pedal-force and depression-duration;
a controller in communication with the brake-pedal, wherein the controller operates the system into a first-mode in response to the brake-pedal being operated in accordance with a first-action-classification, and into a second-mode different from the first-mode in response to the brake-pedal being operated in accordance with a second-action-classification different from the first-action-classification.
2. The system in accordance with claim 1 , wherein the brake-pedal includes a distance-detector that indicates a pedal-deflection-distance to the controller that is indicative of the pedal-force.
3. The system in accordance with claim 1 , wherein the brake-pedal includes a force-detector that indicates the pedal-force to the controller.
4. The system in accordance with claim 1 , wherein the brake-pedal includes an actuation-switch that provides an indication to the controller of when the brake-pedal has been pressed, and the controller determines the depression-duration based on the indication of when the brake-pedal has been pressed.
5. The system in accordance with claim 1 , wherein the first-action-classification is characterized by the pedal-force being less than a force-threshold and the second-action-classification is characterized by the pedal-force being not less than the force-threshold.
6. The system in accordance with claim 1 , wherein the first-action-classification is characterized by the depression-duration being less than a duration-threshold, and the second-action-classification is characterized by the depression-duration being not less than the duration-threshold.
7. The system in accordance with claim 1 , wherein the first-action-classification is characterized by the pedal-force being less than a force-threshold and the depression-duration being less than a duration-threshold, and the second-action-classification is characterized by the pedal-force being not less than the force-threshold and the depression-duration being not less than the duration-threshold.
8. The system in accordance with claim 1 , wherein the system is characterized as an adaptive-cruise-control-system, the first-mode is characterized by disengaging acceleration-control while maintaining deceleration-control, and the second-mode is characterized is characterized by disengaging both acceleration-control and deceleration-control.
