An in-vehicle driving assistance apparatus includes an automatic garage leaving control unit that performs automatic garage leaving cooperation control in which the automatic garage leaving control unit cooperates with a shutter control apparatus to cause a vehicle to automatically leave the garage. The automatic garage leaving control unit acquires vehicle surrounding information on presence or absence of abnormality around the vehicle when the automatic garage leaving control unit accepts an automatic garage leaving request signal, transmits an open request signal requesting to open a shutter to the shutter control apparatus when the automatic garage leaving control unit determines based on the vehicle surrounding information that a space around the vehicle is safe, and suspends the automatic garage leaving cooperation control when the automatic garage leaving control unit determines that abnormality is present around the vehicle.

A mobile machine includes controllable mechanism that performs a prescribed operation on a worksite as the mobile machine travels over the worksite in a direction of travel, and a communication system that receives attribute data indicative of an attribute corresponding to the worksite, and that receives effect data indicative of an effect of the prescribed operation being performed on the worksite. The mobile machine may further include a control system that generates a difference map indicative of a difference between the attribute data and the effect data, and that controls the controllable mechanism to adjust performance of the prescribed operation on the worksite, based on the difference.

A motor control apparatus that vector-controls a sensorless motor includes an estimating unit configured to obtain an estimated phase value by estimating a phase of a rotor in the sensorless motor, and a generating unit configured to generate, from the estimated phase value and a phase command value of the rotor, a phase conversion value that is used for a coordinate conversion between a rotary coordinate system and a static coordinate system in the vector control. The generating unit is further configured to output the phase command value as the phase conversion value when the rotor is caused to start to rotate, and change the phase conversion value so that the phase conversion value approaches the estimated phase value from a predetermined timing after the rotor is caused to start to rotate.

A gaseous-fluid environmental sensor having a gaseous-fluid flow system that defines a flow path coupling an intake port to an exhaust port. The gaseous-fluid flow system includes a blower and a flow sensor. The blower includes a motor and the flow sensor senses a flow-related parameter. The gaseous-fluid environmental sensor further includes a battery, an electrical sensor sensing an electrical power-related parameter, and a controller electrically coupled to the electrical sensor, the flow sensor, and the motor. The controller is configured to generate a composite drive waveform having a first component based on the sensed flow-related parameter and a second component based on the sensed electrical power-related parameter. The controller is further configured to drive the motor using the composite drive waveform. Also disclosed is a method of controlling the gaseous-fluid environmental sensor.

Techniques for navigating semi-autonomous mobile robots are described. A semi-autonomous mobile robot moves within an environment to complete a task. A navigation server communicates with the robot and provides the robot information. The robot includes a navigation map of the environment, interaction information, and a security level. To complete the task, the robot transmits a route reservation request to the navigation server, the route reservation request including a priority for the task, a timeslot, and a route. The navigation server grants the route reservation if the task priority is higher than the task priorities of conflicting route reservation requests from other robots. As the robot moves within the environment, the robot detects an object and attempts to classify the detected object as belonging to an object category. The robot retrieves an interaction profile for the object, and interacts with the object according to the retrieved interaction profile.
