A method of assessing an area for parking a vehicle includes ultrasonically scanning the area to obtain ultrasonic data, radar scanning the area to obtain radar data, and determining whether to park the vehicle in the area based on both the ultrasonic data and the radar data.

Active park assist object detection

A method of determining an object distance from a vehicle includes sending a first transmission signal during a first burst period from a first transmitter, listening for a first reflection signal during a first listen period in a receiver, and sending a second transmission signal during a second burst period from a second transmitter. The second transmission signal is sent based on a time when the first transmission signal is sent.

Park assist object distance measurement clock control

A method of parking a vehicle includes calibrating a wheel speed count of the vehicle based on a measured length that is external to the vehicle, and parking the vehicle based on the calibrated wheel speed count.

Enhanced park assist wheel speed compensation technique

A method of parking a running vehicle includes measuring a length of a parked vehicle that is proximate to a desired parking location, and estimating the width of the parked vehicle based on a regression equation. The running vehicle is parked based on the estimated width.

Enhanced alignment method for park assist

Temperature compensation for ultrasonic sensors can have a significant error that is highly undesirable because temperature of ultrasonic sensors and the temperature of the medium through which they sense objects affect signal strength calibrations (e.g., echo thresholds) applied when detecting an object. In order to increase the detection capabilities and reported distance of an object, ultrasonic sensors need to adjust their detection criteria and distance calculations as the temperature of air surrounding a vehicle (i.e., outside air temperature) changes and also as the temperature of the sensor changes. Embodiments of the inventive subject matter provide for a simple, effective and consistent approach for determining a temperature upon which such detection criteria and distance calculation adjustments can be based.
