A restraint control system of a vehicle includes: a position module configured to determine positions of seats within a passenger cabin of the vehicle; a restraint control module configured to, in response to detection of a collision of the vehicle: select which ones of the restraints of the vehicle to activate based on the positions of the seats; activate the selected restraints of the vehicle; and not activate non-selected ones of the restraints.

The present disclosure discloses a wireless sensing system of a seat position and a control method of the sensing system, the system including a slave control unit provided for each seat to detect a seat belt fastening status and a seat occupancy status by a passenger, and a master control unit provided in a vehicle to receive data based on a radio signal of the slave control unit through radio communication with each slave control unit, calculate a position of each slave control unit based on the data received through the radio communication, and discontinue a position checking of a slave control unit when it is determined that the position of the slave control unit calculated for each slave control unit is outside the vehicle.

A vehicle interlock system includes a wheelchair fixing device configured to fix a wheelchair to a vehicle, a seatbelt device having a seatbelt configured such that, an occupant seated in the wheelchair wears the seatbelt, and a control unit. The control unit is configured to limit at least one of an upper limit traveling speed and an upper limit acceleration of the vehicle or output a warning signal, or to output a warning signal while limiting at least one of the upper limit traveling speed and the upper limit acceleration of the vehicle depending on at least one of the following conditions: whether the wheelchair is fixed to the vehicle with the wheelchair fixing device; whether the occupant is wearing the seatbelt; and so forth.

A vehicular belt tactile apparatus is provided. The apparatus includes a buckle, a belt configured to be fastened to the buckle and at least one air pouch disposed at a portion of the belt that contacts the body of an occupant when the belt is fastened to the buckle. An air controller generates a control signal when the belt is fastened to the buckle. The buckle includes an air supply unit that is configured to inject air into the at least one air pouch through the belt or to discharge air from the at least one air pouch in response to the control signal.

The present disclosure relates to methods and systems for determining a state indicating whether a seat belt of a vehicle is used. A computer implemented method for determining a state indicating whether a seat belt of a vehicle is used comprises: acquiring at least one image of a portion of an interior of the vehicle; determining whether the at least one image comprises a buckle receiver; if it is determined that the at least one image comprises the buckle receiver, determining the state based on the image, and otherwise performing: extracting, from the acquired image, information related to a user of the seat belt and/or information related to a buckle of the seat belt; determining a probability of a change of the state based on the extracted information, and updating the state based on the determined probability.
