A door-mounted air bag and a control method for deploying the same are proposed. The door-mounted air bag is configured to minimize injuries to a passenger on a two-wheeled vehicle and a passenger in a vehicle when the passenger on the two-wheeled vehicle hits a door, and the door-mounted air bag includes a door-mounted air bag including: an air bag mounted to a door, and a cushion provided in the air bag and configured to be deployed in an inward direction of the door, and configured to be deployed in a form that covers an inner surface of a door trim and an edge of a door rear end.

An automatic seat belt retractor includes a belt reel configured to wind a seat belt and a sensor configured to permanently record a rotational speed of the belt reel. The sensor cooperates with an element that is speed-coupled to the belt reel to record the rotational speed. The automatic seat belt retractor includes a brake unit configured to decelerate the seat belt being unwound from the belt reel with a restraining force and a control module configured to control the brake unit with respect to the restraining force as a function of the rotational speed.

From a set of point data, a set of scattered rays is constructed. From the set of scattered rays, a set of ray slopes is computed. The set of ray slopes is mapped to a corresponding set of trigonometric functions. Using an optimization method, a parameter of the set of trigonometric functions is selected. Using an inverse of the set trigonometric functions, a vehicle mass corresponding to the set of point data is computed. Based on the vehicle mass, a threshold braking distance of a collision avoidance system of the vehicle is adjusted, the threshold braking distance comprising a distance from an object predicted to collide with the vehicle. By braking the vehicle at least the threshold braking distance from the object, a predicted collision between the vehicle and the object is avoided.

A wireless airbag control system includes a central master electronic control module having an RF transceiver. One or more slave nodes are provided, each slave node being associated with an airbag that is mounted to perform an operating function with respect to a mechanical device. Each slave node further includes an RF transceiver, a central processing unit and a CAN controller. Two-way communication is shared between the slave nodes and the master electronic control module on a prioritized message basis.

A rescue system includes an inflatable rescue cushion at the bottom of an automobile, which includes air cushion storage chambers in front, back, left, and right of the bottom of the automobile. A gas generator is correspondingly arranged in the air cushion storage chamber in each position, for inflating and opening air cushions in the corresponding air cushion storage chambers to form a front, back, left and right air cushion. The system also includes an electronic early warning and central processing collaboration part, which includes an external water level sensor, central collaborative processing unit, first grade early warning signal light, and a switch. The external water level sensor is connected to the central collaborative processing unit, which is connected to the warning signal light, the gas generator, and the automobile computer board. The switch is positioned in the automobile and is connected to the gas generators.
