Abstract: A method for controlling a steering system in a motor vehicle, which system is designed to convert a steering wheel angle to a steering angle of a steered wheel of the motor vehicle in order to control a yaw angle of the motor vehicle. The method comprises steps of sampling oscillations of the steering wheel angle and of the yaw rate, detecting a predetermined phase difference between the oscillation of the steering wheel angle and the oscillation of the yaw rate, and increasing damping in the conversion of the steering wheel angle to the steering angle.

Abstract: Systems and methods are provided for sequentially updating a Kalman filter in a navigation system. Respective signals from a plurality of transmitters containing range-finding data are received at a plurality of antennas. For each of the plurality of transmitters, a single differenced observable is calculated between a given pair of the plurality of antennas.

A plurality of states stored in the Kalman filter are updated using the double differenced residual values.

Abstract: A vehicle includes a power source, such as an engine, an electric machine, or combination thereof. A torque converter is selectively coupled to the power source such that drive torque can be altered before being distributed into a transmission of the vehicle. A torque converter bypass clutch enables torque from the power source to selectively transmit directly to the transmission with little or no torque altering provided by the torque converter. At least one controller in the vehicle is in communication with a storage device. The controller sends road condition data to the storage device regarding a road segment. During a subsequent drive to or over the road segment, the controller receives the road condition data and enables the torque converter bypass clutch to slip to dampen driveline disturbances when the vehicle passes over the road segment.

Abstract: A brake force control apparatus includes a diagonal two-system brake device and performs front-rear wheel distribution control of brake force by individually controlling the brake pressure of the left and right rear wheels so as to obtain a target relationship between a wheel speed of the left and right rear wheels and the front wheels during braking. It is determined whether or not a difference in wheel speed between one wheel of one system and one wheel of the other system or a difference in wheel speed between the other wheel of the one system and the other wheel of the other system exceeds a threshold. When the threshold is exceeded, the reduction of brake pressure by the front-rear wheel distribution control of brake force is not performed with respect to a rear wheel with a lower wheel speed from among the left and right rear wheels.

Abstract: An automated child safety unlocking system for automobiles which disengages the child safety locks and unlocks the doors at appropriate times during events such as vehicle crashes. The vehicle ECU continually monitors the status of the vehicle to check if a crash event has occurred via various methods such as the status of airbag deployment, accelerometers placed in the car, and crumple points. In the event of a crash the vehicle ECU transmits one of at least two CSL command signals a child safety lock ECU. The command signals are each specific to an event severity and event type, and the child safety lock ECU then interprets the signal and acts according to the signal type. If the data interpreted indicates a crash, the child safety lock ECU unlocks the child safety locks, and if it does not determine a crash has not occurred, the locks remain engaged.

Abstract: An output signal device and method that provides the operator force feedback similar to a pilot control joystick. These force feedback regions include free play, dead-band start of modulation, modulation, fore-warning bumper and hold near max angle.

This improves signal accuracy and provides a service prognostic signal. The prognostic signal may be used to activate redundant sensor. The variable force feedback may improve operation on rough terrain. The force feedback, may allow more productive operating positions to be learned. This enables productivity and other important job site criteria such as fuel usage to be optimized by interactive communication with this output signal device.
