Abstract
A feature avoidance system for a vehicle including at least one ultrasonic sensor disposed on a vehicle and communicatively coupled to a vehicle controller. A dynamic vehicle model is stored in the controller. The dynamic vehicle model is a computer model of current and expected dynamic vehicle component positioning. An analysis module configured cause at least one of the controller and a remote processing system to identify a feature at least partially via data from the at least one ultrasonic sensor, compare a predicted feature position and an estimated vehicle component position, and generate an output in response to the predicted feature position and the estimated vehicle component position intersecting.
Claims19
A feature avoidance system for a vehicle comprising:
- at least one ultrasonic sensor disposed on a vehicle and communicatively coupled to a vehicle controller;
- a dynamic vehicle model stored in said controller, the dynamic vehicle model being a computer model of current and expected dynamic vehicle component positioning;
- an analysis module configured cause at least one of the controller and a remote processing system to identify a feature at least partially via data from the at least one ultrasonic sensor, compare a predicted feature position and an estimated vehicle component position, and generate an output in response to the predicted feature position and the estimated vehicle component position intersecting.
A method for detecting and avoiding feature collisions in a commercial vehicle comprising:
- generating a three-dimensional map of an environment based on sensor measurements from at least one ultrasonic sensor and locating the vehicle within the three-dimensional map;
- identifying at least one feature within the three-dimensional map distinct from the vehicle;
- comparing a predicted position of the at least one feature and an estimated vehicle component position at a future time;
- and
- generating an output in response to the predicted feature position and the estimated vehicle component position intersecting.
