A system includes a seat belt routing module and a user interface device (UID) control module. The seat belt routing module is configured to: determine a routing of a seat belt relative to an occupant in a vehicle seat based on input from a webbing payout sensor; and determine the seat belt routing based on an input from an in-cabin sensor. The in-cabin sensor includes at least one of a camera, an infrared sensor, an ultrasonic sensor, a radar sensor, and a lidar sensor. The UID control module is configured to control a user interface device to indicate that the seat belt is being worn improperly when: the seat belt routing determined using at least one of the webbing payout sensor and the in-cabin sensor is improper; and the seat belt routing determined using the webbing payout sensor corresponds to the seat belt routing determined using the in-cabin sensor.

Aspects of the disclosure relate to determining and responding to an internal state of a self-driving vehicle. For instance, an image of an interior of the vehicle captured by a camera mounted in the vehicle is received. The image is processed in order to identify one or more visible markers at predetermined locations within the vehicle. The internal state of the vehicle is determined based on the identified one or more visible markers. A responsive action is identified action using the determined internal state, and the vehicle is controlled in order to perform the responsive action.

A child safety seat is provided and includes a base, a seat body and a notifying system. The seat body is movable relative to the base between a first position and a second position. The notifying system includes at least one actuated device disposed on one of the base and the seat body, an actuating component disposed on another one of the base and the seat body, and a notifying device electrically connected to the at least one actuated device. When the seat body reaches at least one of the first position and the second position, the actuating component actuates the at least one actuated device, so that the at least one actuated device is actuated to generate different types of actuating signals. The notifying device generates different types of notifying signals when the at least one actuated device generates the different types of actuating signals.

A seating detection method includes: detecting whether a seat belt sensor in a vehicle seat is in an ON state or an OFF state; detecting whether a pressure sensitive sensor in a seat skin constituting a seating surface is in an ON state or an OFF state; and determining a foreign object insertion state in which a foreign object is inserted between the seating surface and a child seat based on whether the seat belt sensor is in the ON state or the OFF state and whether the pressure sensitive sensor is in the ON state or the OFF state. When the pressure sensitive sensor is changed from the ON state to the OFF state in a state in which the seat belt sensor is maintained in the ON state after the seat belt sensor is changed to the ON state, it is determined as the foreign object insertion state.

A universal reminder device in the form of a series circuit including a power source, a warning indicator, a pressure-sensitive normally closed momentary switch, and a pressure-sensitive normally open momentary switch.

A vehicle includes a safety device, a camera sensor configured to detect an obstacle around the vehicle, a radar sensor configured to detect the obstacle around the vehicle, and a controller configured to predict a collision state and a collision position of the vehicle through the camera sensor and the radar sensor, determine whether to control the safety device based on at least one of a vehicle type, a collision speed, a seat position of an occupant, whether the occupant wears a seat belt, a gender of the occupant, whether the occupant is an infant, or a size of the occupant, in response to a prediction result, and control the safety device depending on device determination result.

The proximity alarm and child seat pressure sensor is a safety device. The proximity alarm and child seat pressure sensor detects the presence of a child in a child safety seat. The child is in the custody of a custodian. The proximity alarm and child seat pressure sensor measures the span of the distance between the child safety seat and the custodian. If, while a child is detected in the child safety seat, the span of the distance between the child safety seat and the custodian is greater than a previously determined distance, the proximity alarm and child seat pressure sensor sends an alarm directly to the custodian. If the custodian fails to respond to the alarm within a previously determined amount of time, the proximity alarm and child seat pressure sensor sends an alarm informing the appropriate authority of the location of an unattended child.

A vehicle has a restraint system with at least two restraint devices. A sensor detects a potential collision object and outputs a signal representing a relative position of the potential collision object to the vehicle. A processing device suppresses deployment of at least one of the restraint devices based at least in part on the signal output by the at least one sensor.

A vehicle seat occupancy classification system having at least one weight-responsive sensor, including a supporting plate, a collecting plate, a hinge member mechanically connecting the supporting plate and the collecting plate, at least one elastic spring member, and a position sensor that is configured to determine a gap dimension between the supporting plate and the collecting plate. The occupancy seat classification system includes an evaluation unit that is configured to receive the output signal from the position sensor and to provide a seat occupant classification based on a level of the received output signal and at least a first pre-determined threshold value of the output signal.
