This document describes near-object detection using ultrasonic sensors. Specifically, when an object is in a near-object range or distance from a vehicle, an object-detection system of the vehicle can utilize raw range measurements and various parameters derived from the raw range measurements. The various parameters may include an average, a slope, and a variation of the range. In the near-object range, using the parameters derived from the raw range measurements may lead to increases in the accuracy and performance of a vehicle-based object-detection system. The increased accuracy in near-object detection capability enhances safe driving.

Near-object detection using ultrasonic sensors

This document describes spatial and temporal processing of ultrasonic-sensor detections for mapping in vehicle-parking-assist functions. Specifically, spatial intersections, which are determined from a pair of neighboring ultrasonic sensors having ultrasonic detections at substantially the same time, can address latency issues associated with temporal intersections and can be determined without the vehicle moving. Temporal intersections can address situations when one sensor of the pair of neighboring ultrasonic sensors has an ultrasonic detection while the other sensor does not. Using both the spatial and temporal intersections provides high accuracy for angular information, which enables enhanced mapping and efficient performance of vehicle-parking-assist functions.

A lane keeping system includes an absolute pressure sensor located in a door on each of opposing sides of a vehicle. Each sensor generates a signal indicative of a door cavity pressure on that side of the vehicle. A safety restraint system (SRS) controller is in communication with the pressure sensor. The SRS controller is configured to determine a collision event in response to the signal (e.g., increased pressure in the door as it is crushed) and activate a safety restraint component in response to the determined collision event. A lane keeping system (LKS) controller is in communication with the pressure sensors. The LKS controller determines a lateral wind force on the vehicle in response to the signal from each pressure sensor. The LKS controller determines a correction in response to the determined lateral wind force to maintain the vehicle along a desired path.

A lane keeping system for a vehicle includes a first roll angle sensor configured to provide a first signal indicative of dynamic vehicle body roll. A second roll angle sensor is configured to provide a second signal indicative of an angle between vehicle sprung and unsprung masses. A lane keeping system (LKS) controller is in communication with the first and second roll angle sensors. The LKS controller is configured to discern a vehicle roll angle in response to the first and second signals based upon effects of a lateral wind force on the vehicle. The LKS controller is configured to produce a correction in response to the determined lateral wind force effects to maintain the vehicle along a desired path.

A passive entry passive start (PEPS) vehicle security system configured to thwart a relay attack on the system. The system includes one or more ultra wideband transceivers (UWBX) installed on a vehicle and configured to transmit a request pulse at a request time. A mobile UWBX, possibly installed in a nomadic device such as a smart phone, is configured to transmit a reply pulse in response to the request pulse. A controller is configured to determine a distance between each UWBX and the mobile UWBX based on a time interval between the request time and a time that corresponds to when the reply pulse is received by the each UWBX. The controller may also be configured to unlock doors of the vehicle only if the distance is less than an unlock threshold.

A vehicle pre-impact sensing system is provided that includes an array of energy signal transmitters mounted on a vehicle for transmitting signals within multiple transmit zones spaced from the vehicle and an array of receiver elements mounted on the vehicle for receiving signals reflected from an object located in one or more multiple receive zones indicative of the object being in certain one or more zones. A processor processes the received reflected signals and determines range, location, speed and direction of the object, determines whether the object is expected to impact the vehicle as a function of the determined range, location, speed and direction of the object, and generates an output signal indicative of a pre-impact event. The system may detect one or more features of a target object, such as a front end of a vehicle. Additionally, the system may modulate the transmit beams. Further, the system may perform a terrain normalization to remove stationary items.

An occupant presence sensor apparatus disposed in a seat includes first and second substantially non-compliant force translation plates generally parallel to the seating surface of the seat, an elastomeric mat disposed between the first and second force translation plates, and a switch mechanism disposed between the first and second force translation plates within an opening formed in the elastomeric mat. The elastomeric mat includes a distributed array of hollow protuberances that extend toward and contact the force translation plates, and the mat has a stiffness that normally provides a clearance between the switch mechanism and one of the force translation plates. When an occupant of specified or higher weight sits on the seating surface, the protuberances collapse and the force translation plates activate the switch mechanism.

A method and apparatus is provided for determining seat belt tension in a seat belt system. The apparatus includes webbing and a motor coupled to the webbing for retracting the webbing and generating a seat belt tension. When the seat belt apparatus is deployed to restrain an occupant, the tension on the seatbelt is monitored by applying a voltage to the motor to retract the webbing, measuring an electrical current during the application of the voltage, determining a maximum value of the electrical current and determining the seat belt tension based upon the maximum value.
