Abstract
A system for a vehicle includes a trio of ultrasonic sensors, and a controller configured to, responsive to a location of an object identified from a distance between the ultrasonic sensors, a receive time at each of the ultrasonic sensors associated with a same ultrasonic pulse from a transmitter of the object, and an absence of data regarding a send time of the ultrasonic pulse, steer the vehicle to the object.
Claims17
A system for a vehicle comprising:
- a trio of ultrasonic sensors;
- and
- a controller configured to, responsive to a location of an object identified from a distance between the ultrasonic sensors, a receive time at each of the ultrasonic sensors associated with a same ultrasonic pulse from a transmitter of the object, and an absence of data regarding a send time of the ultrasonic pulse, steer the vehicle to the object.
A method for a vehicle comprising:
- steering, by a controller, the vehicle to an object responsive to a location of the object being identified from a distance between an outer pair of a plurality of ultrasonic sensors on the vehicle, a receive time at each of the ultrasonic sensors associated with a same ultrasonic pulse from a transmitter of the object, and an absence of data regarding a send time of the ultrasonic pulse.
A vehicle comprising:
- a bumper having sensors thereon;
- and
- a controller configured to steer the vehicle to an object based on a location of the object identified from receive times at each of the sensors associated with a same pulse emitted from the object and an absence of data regarding a send time of the pulse.
