Abstract: A method is provided for resuming the movement of a motor vehicle after unforeseen stopping in an automated parking process performed by a parking assistance system having automated longitudinal and transverse guidance. If the vehicle is stopped, a decision is made about a resumption of movement of the vehicle in the prior direction of travel that existed before the vehicle was stopped. The decision is made in dependence on the remaining travel path from the current position to the next planned stopping point of the trajectory lying in the prior direction of travel. A stopping point of the trajectory can be a reversal point or the final parking position, for example. If the decision is positive, the movement of the vehicle is resumed in the prior direction of travel. If the decision is negative, the movement of the vehicle is resumed against the prior direction of travel. Alternatively, in the case of a negative decision, the movement of the vehicle may not be resumed and the parking process may be ended.

Abstract: A control system for controlling a pitch of a plurality of fan blades of a variable pitch fan driven by an engine of a harvester. The control system comprises first, second, and third feedback devices that provide first, second, and third feedback signals indicative of at least one harvester temperature, an ambient temperature, and an engine load. A controller is operable to receive the first, second, and third feedback signals, lookup an initial pitch setting, generate an initial pitch setting signal, and compare the harvester temperature to a harvester temperature limit and generate a fan reversal signal if certain conditions are met.

The system may include one or more sensors configured to generate output signals conveying information related to the vehicle. In some implementations, the system may detect execution of the driving maneuvers by the vehicle based on a comparison of the information conveyed by the output signals from the sensors to criteria included in the pre-determined driving maneuver profiles.

Abstract: A travel control apparatus is configured to perform an overtaking travel on a host vehicle with a vehicle travelling ahead as an overtaking target vehicle during an autonomous driving of the host vehicle. In a case where the overtaking travel starts, the apparatus determines whether or not the overtaking target vehicle accelerates during the overtaking travel. In a case where it is determined that the overtaking target vehicle accelerates, the apparatus determines whether or not a front vehicle is present in front of the overtaking target vehicle. In a case where it is determined that the front vehicle is not present, the apparatus stops the overtaking travel of the host vehicle, and in a case where it is determined that the front vehicle is present, the apparatus continues the overtaking travel of the host vehicle under a predetermined condition.
Abstract: Method of estimation of the speed of an aircraft relative to the surrounding air, in a reference frame tied to the aircraft estimates an estimated static pressure on the basis of measurements of geographical altitude. The process then estimates a first intermediate variation of the speed of the aircraft relative to the surrounding air using explicitly the fact that the pressure measured by the static probe is falsified by a known quantity under the effect of the speed of the aircraft relative to the surrounding air. Finally, temporal integration of the first intermediate variation of the speed of the aircraft relative to the surrounding air provides an estimated speed of the aircraft relative to the surrounding air.
Abstract: Method and apparatus for a vehicle cruise control, particularly concerning a school bus, which includes collecting information on the school bus and a road environment positioned around nearby vehicle, monitoring position, velocity and moving direction of the school bus, and state of surrounding road. If the school bus is stopped relatively near the front of the nearby vehicle, the method continues by determining whether or not the vehicle is stopped by comparing the collected school bus information and the road environment information with a predefined cruise regulation based on the school bus, and guiding the driver to stop as well as controlling the vehicle to stop depending on the determination result.
Abstract: A working vehicle includes a revolving pump output calculating section that calculates the revolving pump output where the output of an electric motor is converted to be the output of a hydraulic pump. A reduction amount determining section determines a reduction amount for the output of the hydraulic pump during the multiple operations based on the revolving pump output. A pump output determining section determines a value, where the reduction amount is subtracted from the output of the hydraulic pump which is determined according to the state with the multiple operations, in a first control mode as the output of the hydraulic pump during the multiple operations. The pump output determining section increases the output of the hydraulic pump during the multiple operations in a second control mode more than in the first control mode.
Abstract: A target recognition apparatus includes a detecting unit and an estimating unit. The detecting unit detects an object that is present in a traveling direction of a vehicle, and acquires information for estimation that is used to perform an object type estimation to presume whether or not the detected object is an object to be used in control for enabling the vehicle to perform a predetermined operation. The estimating unit performs the object type estimation based on the information for estimation. When a predetermined first condition is met, the control for enabling the vehicle to perform a predetermined operation is prohibited or suppressed. The predetermined first condition indicates that erroneous estimation may occur in the object type estimation.
