Abstract: Systems and methods for reducing the number of runway excursions (i.e., airplanes going off the end of a runway). An alerting system is provided which alerts pilots when computer calculations indicate that current airplane braking is insufficient to keep the airplane from going off the end of the runway. The current airplane braking during rollout is evaluated using algorithms which take into account the current groundspeed of the airplane, the current deceleration rate or the maximum manual deceleration rate of the airplane, and the distance from the current position of the airplane to the end of the runway.

Abstract: According to a vehicle control apparatus of the invention, at a point in time when a driving mode switching part switches driving modes from any driving mode to another driving mode, a reference energy consumption amount calculation part multiplies a reference energy consumption amount by a driving mode switching coefficient which corresponds to the switching of the driving modes, whereby a reference energy consumption amount is compressed or expanded. An energy consumption rate calculation part calculates an energy consumption rate based on a reference mileage and the reference energy consumption amount.

Abstract: A latency analysis system determines a latency period, such as a wait time, at a user destination. To determine the latency period, the latency analysis system receives location history from multiple user devices. With the location histories, the latency analysis system identifies points-of-interest that users have visited and determines the amount of time the user devices were at a point-of-interest. For example, the latency analysis system determines when a user device entered and exited a point-of-interest. Based on the elapsed time between entry and exit, the latency analysis system determines how long the user device was inside the point-of-interest. By averaging elapsed times for multiple user devices, the latency analysis system determines a latency period for the point-of-interest. The latency analysis system then uses the latency period to provide latency-based recommendations to a user. For example, the latency analysis system may determine a shopping route for a user.

Abstract: A method for controlling a hydrostatic drive unit of a work vehicle is disclosed. The method may generally include determining a reference swashplate position for a hydraulic pump of the hydrostatic drive unit, wherein the reference swashplate position is associated with an uncompensated current command, and monitoring an actual swashplate position of the hydraulic pump, wherein the actual swashplate position differs from the reference swashplate position due to a loading condition of the work vehicle. In addition, the method may include determining a current compensation based at least in part on the actual and reference swashplate positions and generating a compensated current command by adjusting the uncompensated current command based on the current compensation, wherein the compensated current command is associated with a compensated swashplate position for the hydraulic that differs from the reference swashplate position.

Abstract: A control device for a vehicle executes an adaptive cruise control and an idle stop control. The control device automatically starts an internal combustion engine when an operation amount of a start operating member different from a brake pedal is larger than or equal to a predetermined amount while the idle stop control is being executed. The control device sets the predetermined amount to a first predetermined amount when the adaptive cruise control is not executed. The control device sets the predetermined amount to a second predetermined amount smaller than the first predetermined amount when the adaptive cruise control is being executed.

Abstract: Hybrid-electric and pure electric vehicles include a traction battery. During vehicle operation, impedance parameters of the traction battery may be estimated. To ensure accurate estimation results, certain persistent excitation criteria may be met. These conditions may not always be met, in which case active excitation of the traction battery power demand may be initiated. The invocation of active battery excitation may be based on a variability of estimates of a battery parameter and an age of a most recent estimate of the battery parameter. As the variability of the parameter estimates increases, the time between active battery excitation requests may decrease.

A passable time zone estimating unit estimates a passable time zone during which the own vehicle is able to pass by the traffic light, based on the one of the number of stopping vehicles and the length of the stopping vehicle line that have been estimated by the stopping vehicle estimating unit, and on schedule information.

Abstract: In one embodiment, a mobile device includes position circuitry and routing algorithms for generating routing instructions from a current position of the mobile device to a destination. The destination is specified in a navigation request and may describe a point-of-interest. A database associates points-of-interest individually or by category with estimated parking durations. The mobile device accesses an estimated parking duration and selects a preferred parking location based on the estimated parking duration. Considerations for selecting the preferred parking location include cost, parking restrictions, and/or distance. For example, the preferred parking location may be the available parking spot that is the least expensive during the estimated parking duration and avoids no parking zones or other time constraints.

The electric drive unit has an electricity storage device, a hydraulic pump of variable displacement type which is driven by a motor/generator, a regulator which performs variable control on the displacement volume of the hydraulic pump, a bidirectional converter which performs variable control on the revolution speed of the motor/generator, and an LS control device which controls the regulator and the bidirectional converter so that LS differential pressure Pls equals a target value Pgr. The bidirectional converter performs regeneration control for converting the inertial force of the rotor of the motor/generator into electric power thereby charging the electricity storage device when the revolution speed of the motor/generator is decreased in response to an excess of the LS differential pressure Pls over the target value Pgr.

Abstract: A method for calculating a virtual target path around a target object that includes providing scan points identifying detected objects and separating the scan points into target object scan points and other object scan points. The method identifies a closest scan point from the target object scan points and identifies a path point that is a predetermined safe distance from the closest scan point. The method determines a straight target line adjacent to the target object that goes through the path point, and determines a distance between the target line and each of the other objects and determines whether all of the distances are greater than a predetermined threshold distance. The method identifies curve points for each other object whose distance is less than the predetermined threshold distance, and identifies a curve path that connects the curve points to be the virtual target path using a quadratic polynomial function.
