Abstract: A computer-implemented method of using telematics data at a destination device is provided. The destination device may be a mobile device associated with a driver, or a smart vehicle controller of a destination vehicle.

Abstract: A control system uses visual odometry (VO) data to identify a position of the vehicle while moving along a path next to the row and to detect the vehicle reaching an end of the row. The control system can also use the VO image to turn the vehicle around from a first position at the end of the row to a second position at a start of another row. The control system may detect an end of row based on 3-D image data, VO data, and GNSS data. The control system also may adjust the VO data so the end of row detected from the VO data corresponds with the end of row location identified with the GNSS data.

Abstract: A driving analysis server may be configured to receive vehicle operation data from mobile devices respectively disposed within the vehicles, and may use the data to group the vehicles into multiple groups.

A driver score the outliers may be adjusted positively or negatively based on whether the outlier behaved in a manner more or less safe than its group. Further, unsafe driving events performed by the outlier that were the result of another vehicle's unsafe driving event may be ignored or positively accounted for in determining or adjusting the outlier's driver score.

Abstract: A method of controlling a propulsion system on a marine vessel includes receiving proximity measurements describing locations of one or more objects with respect to the marine vessel, receiving a command vector instructing magnitude and direction for propulsion of the marine vessel with respect to a point of navigation for the marine vessel, and then determining a funnel boundary based on the command vector. An object is identified based on the proximity measurements and determined to be within the funnel boundary, and then a propulsion adjustment command is calculated based on the command vector and an angle of the object with respect to the point of navigation. At least one propulsion device is then controlled based on the propulsion adjustment command in order to avoid the object.

Abstract: A method for operating a motor vehicle having partial/full autonomous driving, having a plurality of wheels, a drive system for producing a drive torque at at least one of the wheels, and a brake system for producing at least one holding force for holding still at least one of the wheels, a rotational speed sensor being allocated to at least one of the wheels, which sensor produces a respective signal pulse for each of a plurality of positions of angular rotation of the associated wheel, a specifiable driving maneuver being performed as a function of the produced signal pulses. For a short path driving process starting from a standstill, the brake force is reduced until the rotational speed sensor produces a first signal pulse, and is then held at least temporarily constant until a specified number of signal pulses is produced, and subsequently is increased up to the holding force.

Abstract: A positional sensor detects a current position and a current bearing of a boat body and outputs position information indicating the current position and the current bearing. A controller receives the position information. The controller determines a first target position of the boat body and a target bearing in the first target position. The controller calculates a bearing difference between the current bearing and the target bearing. The controller determines an offset amount of the first target position in response to the bearing difference or an outside disturbance. The controller determines a position spaced away by the offset amount from the first target position on a side toward the current position as a second target position. The controller generates an instruction signal to control a propulsion device so as to cause the boat body to arrive at the second target position.
