Patent attributes
Automated collision warnings may be provided by stationary vehicles. Stationary vehicles may monitor the external environment of the vehicle for moving objects. If a possible collision with a moving object is detected, a collision avoidance action may be selected. The vehicle may be directed to perform the collision avoidance mechanism, which may include visual warnings, auditory warnings, vehicle-to-vehicle warning communications, or automated movement of the stationary vehicle to avoid the collision. A wakeup mechanism may be implemented to reduce power consumption of automated collision warnings by initiating monitoring for possible collision events automatically when a possible collision is likely.
