A restraining device control system includes: a restraining device that is provided at a vehicle seat and that restrains an occupant seated in the vehicle seat; a surrounding environment detection unit that detects an environment surrounding a vehicle; and a control unit that increases a restraining force on the occupant by the restraining device in a case in which it has been predicted, from the surrounding environment of the vehicle, that vacillation of the vehicle while in an autonomous driving mode will exceed a threshold amount and that decreases the restraining force on the occupant by the restraining device in a case in which it has been predicted, from the surrounding environment of the vehicle, that the vehicle will maintain a state in which vacillation of the vehicle while in the autonomous driving mode is less than the threshold amount.

A seatbelt detection system detects seatbelt use in each seat of a passenger aircraft to produce safety-compliance data. A computer system, which is communicatively coupled to the seatbelt detection system, receives sensor data from a plurality of sensors in an aircraft cabin; and employ an artificial intelligence (AI) program to train on input data comprising at least one of safety compliance data, aircraft system data, cabin environment data, cabin operations data, or aircraft operations data; and the AI program is configured to minimize a summed error of predictions of seatbelt compliance.

Devices, systems and processes for the detection of unsafe cabin conditions that provides a safer passenger experience in autonomous vehicles are described. One example method for enhancing passenger safety includes capturing at least a set of images of one or more passengers in the vehicle, determining, based on the set of images, the occurrence of an unsafe activity in an interior of the vehicle, performing, using a neural network, a classification of the unsafe activity, and performing, based on the classification, one or more responsive actions.

A wheelchair-bound passenger restraint device has a wheelchair retractor that rewinds one end portion of a wheelchair belt member in an extractable manner, a wheelchair buckle that can be fitted with a wheelchair tongue plate, a passenger retractor that rewinds one end portion of a passenger belt member in an extractable manner, a passenger buckle that can be fitted with a passenger tongue plate, a buckle sensor that detects that the wheelchair tongue plate has been fitted to the wheelchair buckle, and a passenger belt lock mechanism that is configured to be able to make a changeover between a locked state making the passenger belt member unextractable an unlocked state making the passenger belt member extractable, and that makes a changeover from the locked state to the unlocked state when it is detected that the wheelchair tongue plate has been fitted to the wheelchair buckle.

The present invention relates to a rider holder for an amusement ride (14), comprising a holding portion (16) for holding a rider, a restraining device (24) which can be moved between an open position, in which the rider can access the holding portion (16), and a closed position, in which the held rider in the holding portion (16) can interact with the restraining device (24), a lockable securing device (32) which, in a locked state, fixes the restraining device (24) in the closed position and, in an unlocked state, releases the restraining device (24), and a control unit (52) which has detection means (55), by means of which it can be redundantly determined in a fail-safe manner whether the securing device (32) is in the locked or unlocked state, wherein the control unit (52) generates corresponding state signals. The invention further relates to a vehicle having at least one such rider holder for an amusement ride and to a method for operating such a vehicle. Furthermore, the invention relates to an amusement ride having at least one such vehicle.
