METHOD FOR REDUCING FALSE ACTIVATIONS IN REVERSE COLLISION AVOIDANCE SYSTEMS

摘要

A collision avoidance system for a vehicle is disclosed that includes at least one sensor mounted to a vehicle to measure the vehicle's environment in the reverse driving direction, a controller which creates a feature vector based on relationships among data provided by at least one sensor, and a non-volatile memory which stores feature vectors and related object configurations for a number of different environments. The system utilizes a comparison between the current feature vector and previously stored feature vectors to match the current environment with a previously observed environment, and then loads a previously stored object configuration which can improve collision detection performance to reduce the number of unnecessary system interventions.

1. A reverse collision avoidance system for a vehicle comprising:
at least one sensor mounted to the vehicle to detect objects proximate to a path of the vehicle; a controller including instructions for:
analyzing data from the sensors to determine a current feature vector based upon data from the at least one sensor;storing the current feature vector and associated object configuration for the environment in non-volatile memory for the collision avoidance system;comparing the current feature vector with previously stored feature vectors; and selecting an object configuration representing the environment surrounding the vehicle based on the comparison of the current feature vectors with previously stored feature vectors.
