Changes to the baseline trajectory are received by a computer system associated with the vehicle. The computer system creates a function representing the current trajectory of the vehicle, as well as one or more functions defining any desired trajectory criteria, and generates an optimization problem from the functions, which, when solved, provide a new trajectory for the vehicle to follow that moves efficiently and smoothly toward the changed baseline trajectory.

Abstract: A system and method involve determining the airspeed of a vehicle using the propagation time of an acoustic signal from a transmitter located at one end of the vehicle to a receiver located at the other end of the vehicle. A digital representation of the acoustic signal is created and stored within non-volatile memory within the transmitter, then converted into an electrical signal which is filtered, amplified, and input into a transducer contained within the transmitter. The transducer radiates an acoustic signal toward the receiver, which receives and filters the acoustic signal, converts it into a digital signal, and processes the digital signal to determine the acoustic signal propagation time. The acoustic signal may have a continuous wave form, a duty cycle of about 100%, a peak to average amplitude ratio of less than about 2.5, and Fourier components of substantially equal amplitude and random phase.

Abstract: A steering system for a towable implement includes a steering sensor, an implement steering controller, a steering control valve, a steering cylinder, and an implement steering mechanism that steers the implement. The steering sensor measures, directly or indirectly, the angular position of the steerable wheels of the implement. The implement steering controller processes feedback from the steering sensor and with a desired steering angle, outputs a steering control signal that is input to the steering control valve. The steering control valve controls the flow of hydraulic fluid to the steering cylinder, which, in turn, powers the implement steering mechanism to turn the wheels of the implement. The steering system may be operated in various control modes, such as, a transportation steering mode, a corner and 180 turn steering mode, a swath tracking steering mode, crab steering mode, and a manual steering mode, which allows manual control of the steering system.

Abstract: Disclosed is a technique for compensating for an abnormal output of a resolver. More specifically, a central processing unit (CPU) sets a current motor position angle before compensation ?n,ORG as a current motor position angle ?n and obtains a motor position change ??n[rad] between a current sampling [n] and a previous sampling [n?1] and a motor position change ??n-1[rad] between the previous sampling [n?1] and a more previous sampling [n?2]. Subsequently, a variable A is calculated based on the above angles. The CPU determines whether to perform the compensation by comparing the calculated variable A and a calibration variable K and calculates a current motor position angle for compensation ?n[rad]. Finally, the CPU compensates for the absence of motor rotor position information with the calculated current motor position angle for compensation ?n[rad].

Abstract: A method for determining the return spring pressure of a clutch in a vehicle transmission includes using proportion-integral-derivative (PID) control logic of a controller to introduce a calibrated error into a pressure command of a holding clutch during a coast-down maneuver of the vehicle. The calibrated error causes a slip level to occur across the holding clutch. The method includes maintaining the slip level using the PID control logic and separately commanding engine torque at different threshold low values during the coast-down maneuver. The pressure/input torque relationship for the holding clutch is recorded for both threshold low levels as the controller continues to maintain the slip. The return spring pressure is calculated using the recorded pressure/input torque relationship. The holding clutch may be controlled a subsequent shift maneuver using the learned return spring pressure. A vehicle is also disclosed having a controller configured to execute steps of the method.

Abstract: The described method and system provide for GPS navigation utilizing an EHPE (estimated horizontal positioning error) timer for reducing route calculation failures. By utilizing an EHPE timer, a GPS unit may continue to check for GPS signal until the EHPE timer expires before reporting route calculation failure to the user. Thus, in situations where GPS signal is only temporarily lost and current location information is only temporarily degraded, user route requests will not necessarily result in route calculation failure. In preferred implementations, the system and method are implemented within the context of a telematics unit in a vehicle or in the context of a call center.
