A method and apparatus for harvesting a static electric charge from suspended particles in an atmosphere includes exposing a charge conductor to the suspended particles in the atmosphere and selectively providing a conductive path between the charge conductor and a terrestrial ground including a rechargeable energy storage device. Energy may be selectively transferred to another energy storage device.

The present application relates to a method and apparatus for generating a graphical user interface indicative of a vehicle underbody view including a LIDAR operative to generate a depth map of an off-road surface, a camera for capturing an image of the off-road surface, a chassis sensor operative to detect an orientation of a host vehicle, a processor operative to generate an augmented image in response to the depth map, the image and the orientation, wherein the augmented image depicts an underbody view of the host vehicle and a graphic representative of a host vehicle suspension system, and a display operative to display the augmented image to a host vehicle operator. A static and dynamic model of the vehicle underbody is compared vs the 3-D terrain model to identify contact points between the underbody and terrain are highlighted.

The present application relates to a method for performing off road adaptive cruise control in a host vehicle including controlling a vehicle speed at a first speed according to an adaptive cruise control algorithm, detecting an obstacle, using a sensor, within a host vehicle path, reducing the vehicle speed to a reduced speed in response to the detection of the obstacle, detecting a vehicle contact with the obstacle in response to a first inertial measurement unit measurement, applying a brake friction force and increasing an engine torque in response to detecting the vehicle contact with the obstacle, determining a traverse of the obstacle in response to a second inertial measurement unit measurement, and resuming the control of the vehicle speed at the first speed in response to the traverse of the obstacle.

A cargo management system for a vehicle includes a beam assembly that has a first end and a second end. At least one of the ends is biased axially outward and compressible axially inward. Each of the ends has a common interface configured to be supportable by the opposing side walls of the vehicle so that the beam assembly is supported at both of the first and second ends by the walls and extends over a floor of a vehicle, with said at least one of the ends compressed axially inward. The beam assembly can be used as a bed divider, to provide two-tier loading, and as a ladder rack.

Multi-functional cargo management system for a vehicle

An engine control system comprises a limit determination module and a torque control module. The limit determination module selectively varies a torque limit based on a steering angle. The torque control module selectively limits torque output by an engine to the torque limit.

Driveline protection systems and methods using measured steering angle

A control system for an engine that includes a turbocharger includes a restriction estimation module and an engine protection module. The restriction estimation module estimates restriction of airflow through an air filter of the engine based on a comparison between measured and modeled temperatures at an outlet of a compressor of the turbocharger. The engine protection module, based on the estimated airflow restriction, at least one of controls turbocharger boost, controls turbocharger airflow, controls a fueling rate of the engine, and generates a warning signal for a driver of a vehicle.

An exhaust system for a vehicle having a diesel engine and a method of operation are disclosed. The exhaust system may include a diesel particulate filter, a pipe located downstream of the diesel particulate filter and an exhaust gas cooling assembly. The exhaust gas cooling assembly may have an air pump and a connecting pipe connected to the pipe and configured to direct air from the air pump into the pipe. During particulate filter regeneration, the air pump may be activated to push air into the exhaust in order to reduce the temperature of exhaust gasses exiting the vehicle.

Diesel exhaust gas temperature reduction

A fluid entrainment apparatus is provided which operates to mix a first fluid stream with a second fluid stream. The apparatus includes first and second fluid flow conduits. The first fluid flow conduit includes a nozzle portion having a converging bore through which the first fluid is accelerated. Additionally, the second fluid flow conduit includes a nozzle portion having a converging bore, a duct portion having a generally cylindrical bore, and a diffuser portion having a diverging bore. The nozzle portion of the second fluid flow conduit is mounted with respect to the nozzle portion of the first fluid flow conduit such that an annular port is formed through which the second fluid passes to mix with the first fluid. Additional fluid mixing occurs in the duct portion and the diffuser portion. The fluid entrainment apparatus may be configured for use within a vehicle exhaust system.
