Abstract: A method for adjusting a seat in a vehicle includes adjusting the seat from an initial position to a passenger adjusted position based on receiving an input from a passenger. The method further includes determining the passenger exited the vehicle after adjusting the seat and predicting a likelihood of the passenger returning to the vehicle based on determining the passenger exited the vehicle. The method also includes adjusting the seat to the initial position based on the likelihood of the passenger returning is less than a passenger returning threshold. The method still further includes identifying a person approaching the vehicle after the passenger exited the vehicle based on information captured by one or more sensors of the vehicle. The method also includes adjusting the seat to a position associated with the previous passenger based on identifying the person approaching the vehicle as the previous passenger.

Abstract: A control device for a vehicle comprises: a communication section configured to receive first information from a sensor installed at a tire, and receive second information from a sensor installed at a vehicle body; and a controller configured to estimate a wheel load from the first information, estimate a vehicle weight from the second information, and control the vehicle based on one of the wheel load and the vehicle weight.

Abstract: A tire state monitoring system comprises an acquisition device and a control device. The acquisition device is configured to repeatedly acquire a pressure and temperature inside a tire. The control device is configured to: calculate, based on ratios between the pressure and temperature acquired in a first period, a representative value of the ratios in the first period; and compare a ratio between the pressure and temperature acquired in a second period after the first period with the representative value, to determine whether the pressure inside the tire has dropped.

Abstract: A tire air pressure monitoring system includes: a data acquisition unit that acquires tire air pressure data at each fixed detection period; a storage unit that stores newly acquired air pressure data P(0), and air pressure data P(1) to P(N) acquired 1 to N periods prior to the air pressure data P(0); a determination unit that determines a state in which air pressure has decreased, on the basis of air pressure data; and a communication unit that transmits a determination result of the determination unit to an external device, in which the determination unit compares each piece of the air pressure data P(1) to P(n) with the air pressure data P(0) to calculate decrease values, compares the decrease values with a preset first threshold value (th1), and determines that tire air pressure is decreasing when at least one decrease value is greater than or equal to the first threshold value.

Abstract: An electric vacuum cleaning apparatus that offers a high degree of convenience is provided that is capable of easily switching between a function that empties dust from an electric vacuum cleaner by moving dust collected by the cleaner to a station and accumulating the dust at the station, and a function that accumulates dust that is swept up together after quickly performing localized cleaning using an cleaning implement other than the cleaner at the station.

Abstract: A vacuum cleaner includes a main casing, driving wheels, side brushes, an obstacle sensor, and a controller. The driving wheels enable the main casing to travel. The side brushes are reciprocatively movable in both a direction of protruding from an outer frame of the main casing and its opposite direction, enabling cleaning of dust and dirt located outside the outer frame of the main casing. The obstacle sensor detects an obstacle by detecting a movement of the side brush in the opposite direction due to its contact with the obstacle. The controller controls drive of the driving wheels based on detection of an obstacle by the obstacle sensor to make the main casing autonomously travel. The vacuum cleaner can detect an obstacle at a position of a side brush while securely cleaning dust and dirt located outside an outer frame of a main casing by the side brush.

Abstract: A vacuum cleaner capable of ensuring communication between a suction port and a dust collecting unit even in a state that a body portion of a cleaning unit has pivoted along an up/down direction relative to a main casing. The body portion is provided on the main casing to be pivotable along the up/down direction. A sliding-contact surface portion is provided in the body portion and curved along a pivoting direction of the body portion. A curved surface portion is provided in the communicating section body and curved along the pivoting direction of the body portion to be brought into sliding contact with the sliding-contact surface portion by pivoting motion of the body portion. A communicating opening is opened in the curved surface portion to communicate with the dust collecting unit.

Abstract: A vacuum cleaner includes link mechanisms that connect a bumper to be movable in a relatively horizontal direction with respect to a case main body. A coil spring energizes the bumper in a direction separated from the case main body. Obstacle sensors are arranged at positions facing the bumper in the case main body, and detect an obstacle by detecting movement of the bumper, due to contact with the obstacle, in at least one of a direction opposite to an energizing direction of the coil spring and a direction crossing such a direction. A controller controls the drive of a driving wheel based on detection of the obstacle by the obstacle sensor to allow the main body case to travel autonomously. The vacuum cleaner can detect an obstacle brought into contact with the bumper in a wide range with a simple configuration.

Abstract: An electric vacuum cleaner includes a main body case, driving wheels, and a cleaning portion. The main body case includes an electric blower, and a dust collecting portion communicating with a suction side of the electric blower. The driving wheels allow the main body case to travel on the surface to be cleaned. The cleaning portion includes a main body portion, the suction port, and wheels. The main body portion with a bottom surface portion facing the surface to be cleaned is located in a lower portion of the main body case and can move up and down. The suction port is provided on the bottom surface portion and communicates with the dust collecting portion. The wheels protrude downward from the bottom surface portion to contact the surface to be cleaned, thereby causing the main body portion to move up and down to trace the surface to be cleaned.
