An occupant determination apparatus includes a load sensor that detects weight of an occupant seated on a seat of a vehicle, and a determinator determining the weight of the occupant as one status among a plurality of statuses which is set corresponding to the weight based on the measurement weight measured by the load sensor. In a case where an absolute value of acceleration acting on the vehicle becomes equal to or larger than the threshold value set in advance, the determinator determines the weight of the occupant as one of the status among the plurality of statuses based on the measurement weight measured before it becomes the threshold value.

An occupant support for a vehicle includes a vehicle seat and a foundation. The vehicle seat is configured to support an occupant of the vehicle above a floor of the vehicle. The foundation is configured to interconnect the vehicle seat to the floor to permit movement of the vehicle seat relative to the floor along a linear path.

A seat state detection apparatus according to the present invention includes: a detecting unit configured to, in accordance with a moving operation in a front-rear direction by an operator on a seat of a vehicle, detect a moving status value representing a status of a moving mechanism that moves the seat in the front-rear direction; and a determining unit configured to determine that the moving mechanism is in a first state when the detected moving status value is more than a first threshold value, and determine that the moving mechanism is in a second state when the detected moving status value is less than a second threshold value set to a value lower than the first threshold value.

A device and a method for controlling a seat of a vehicle includes a detector for detecting vehicle environment information, a vibration generator mounted on the vehicle seat to generate the seat vibration, and a controller electrically connected to the detector and the vibration generator, and the controller detects seat environment information through the detector, determines a weight and a sitting posture of a user seated in the vehicle seat based on the seat environment information, determines a vibration pattern and a vibration excitation force based on the weight and the sitting posture of the user, and generates the seat vibration by controlling the vibration generator based on the determined vibration pattern and vibration excitation force.

Arrangements related to the operation of an autonomous vehicle are described. The autonomous vehicle includes a vehicle seat. It can be determined whether a future planned driving maneuver of the autonomous vehicle includes a change in a current motion of the autonomous vehicle. Responsive to determining that the future planned driving maneuver includes a change in the current motion of the autonomous vehicle, the vehicle seat can be caused to provide a haptic indication of the future planned driving maneuver prior to implementing the future planned driving maneuver. In this way, a vehicle seat occupant can be alerted to the future planned driving maneuver. The haptic indication can include a movement of the vehicle seat. In one or more arrangements, the movement of the vehicle seat can correspond to a sensation that a vehicle seat occupant will experience during at least a portion of the future planned driving maneuver.

A system for adjusting a position of a wheelchair occupant includes a sensor configured to generate sensor data based on the position of the occupant, an adjustment system coupled to a support point on the wheelchair and configured to be coupled to a support point on the occupant's clothing, and a processing circuit. The adjustment system is configured to extend and retract at least one adjustment element to adjust the position of the occupant, and the processing circuit is configured to determine the position of the occupant in the wheelchair based on the sensor data and adjust the adjustment element based on the determined position of the occupant.

A method and apparatus are disclosed for vehicle occupant protection in unintentional roadway departure by a vehicle having at least one vehicle seat with a seat cushion mounted on a seat frame, the height of which is adjustable through a motor operated height adjustment device. Vehicle travel is monitored using a remote sensor and/or a vehicle dynamics sensor. The remote sensor detects edges of the road. The vehicle dynamics sensor determines vehicle dynamics parameters. Road edge signals and/or vehicle dynamics signals are processed to determine whether the vehicle is about to leave the road. Operation of the height adjustment device to move a seat cushion towards a crash-position is triggered in response to an off-road signal indicating that the vehicle is about to leave the road.

Apparatus and methods are described for use of a sensor for monitoring a subject generate a sensor signal in response to the monitoring. Also disclosed is a computer processor to analyze the signal, and in response thereto, identify a correspondence between positions of the subject and occurrences of health events of the subject, and generate an output on the output device, in response to the identified correspondence. Other applications are also described.

Systems, devices, and techniques are provided for occupancy assessment of a vehicle. For one or more occupants of the vehicle, the occupancy assessment establishes position and/or identity for some or all of the occupant(s).

Methods, systems, and apparatus, including computer programs encoded on a storage device, for monitoring a vehicle are disclosed. A vehicle monitoring system for monitoring a vehicle includes one or more processors and one or more computer storage media storing instructions that are operable, when executed by the one or more processors, to cause the one or more processors to perform operations. The operations include: receiving, from a vehicle occupancy monitor and by the vehicle monitoring system, vehicle occupancy data that indicates presence of a vehicle occupant; receiving, by the vehicle monitoring system and from a sensor, sensor data that indicates an attribute of the vehicle; analyzing, by the vehicle monitoring system, the vehicle occupancy data and the sensor data; and based on analyzing the vehicle occupancy data and the sensor data, performing a vehicle monitoring system action.
