20150348417 | BOUNDARY DETECTION SYSTEM - Systems and methods provide for tracking objects around a vehicle, analyzing the potential threat of the tracked objects, and implementing a threat response based on the analysis in order to keep occupants of the vehicle safe. Embodiments include a boundary detection system comprising a memory configured to store threat identification information, and a sensor unit configured to sense the object outside the vehicle and obtain sensor information based on the sensed object. The boundary detection system further includes a processor in communication with the memory and sensor unit, the controller configured to receive the sensor information, and control a threat response based on the sensor information and the threat identification information. | 12-03-2015 |
20150360610 | System and Method for Improving Vehicle Wrong-Way Detection - Systems and methods for improving vehicle wrong-way detection including systems, sensors or features, such as those for system/network clocks, ambient light, driver impairment, automatic cruise control, blind spot warning or configurable vehicle security, either singly or in any combination therewith, may refine and/or modify the confidence level of detecting particular or potential wrong-way incidents. By modifying the confidence level, the system may change the system sensitivity by moving the cutoff point at which an alert activation takes place. The systems described above can modify the wrong-way detection sensitivity. Greater confidence, or system sensitivity, may also help enable the system to take further actions beyond a simple warning. At greater confidence levels, the system could intervene, by way of a non-limiting example, with throttle limiting, turning on the hazard lights or even bringing the vehicle to a stop. | 12-17-2015 |
20160101765 | AUTOMATIC BRAKING OVERRIDE SYSTEM - A vehicle includes a vehicle-driver interface and an automated braking system. The automated braking system is configured to automatically apply vehicle brakes in response to a detected rearward object and the vehicle being in REVERSE. The automated braking system is additionally configured to release the brakes in response to a driver input at the vehicle-driver interface when a distance from the vehicle to the rearward object exceeds a calibratable threshold. The automated braking system is further configured to apply the brakes in response to the vehicle traveling a predefined distance after the driver input. | 04-14-2016 |
