A gas generator includes a supply of stored gas containing carbon dioxide, and a magnesium supply or source, such as magnesium mesh, that is readily ignitable in the presence of carbon dioxide in the presence of heat.

Systems, apparatus and methods implemented in algorithms, hardware, software, firmware, logic, or circuitry may be configured to process data and sensory input to determine whether an object external to an autonomous vehicle (e.g., another vehicle, a pedestrian, road debris, a bicyclist, etc.) may be a potential collision threat to the autonomous vehicle. The autonomous vehicle may be configured to implement interior active safety systems to protect passengers of the autonomous vehicle during a collision with an object or during evasive maneuvers by the autonomous vehicle, for example. The interior active safety systems may be configured to provide passengers with notice of an impending collision and/or emergency maneuvers by the vehicle by tensioning seat belts prior to executing an evasive maneuver and/or prior to a predicted point of collision.

Provided is a security device for a motor vehicle for automatically moving a device of the motor vehicle in a predefined driving situation, including an electric motor for moving the device and a first current supply interface that can be electrically coupled to an on-board current supply system of the motor vehicle. The security device includes a second current supply interface for electrically coupling the electric motor to a drive battery of the motor vehicle. The second current supply interface includes a switching device with switching for electrically coupling the electric motor to the drive battery depending on the predefined driving situation. Furthermore, provided is a security system with several security devices and a method for operating such a security system.

A vehicle pre-crash seat belt device includes: a buckle moving mechanism that moves a buckle, with which a tongue that has a webbing inserted therein engages, between a normal position and a raised position that is further toward a seat upper side than the normal position; a retractor that includes: a spool and a lock mechanism that locks rotation of the spool in the pull-out direction, and that releases the locked state by causing rotation of the spool in the take-up direction; and a controller that, due to a signal from a collision prediction sensor that predicts a collision of a vehicle, causes rotation of the spool in the take-up direction and increases tension acting on the webbing, and actuates the buckle moving mechanism to move the buckle from the normal position toward the raised position in a case in which the vehicle collision has been avoided.

An occupant protecting device for a vehicle, including: a pretensioner applying tension to a webbing that is configured to restrain an upper body of a vehicle occupant seated in a vehicle seat; a vibrating unit configured to vibrate a contact portion to which the vehicle occupant contacts; a single operating section operating the vibrating unit in a case in which an instruction to operate the vibrating unit is received, and operating the pretensioner in a case in which an instruction to operate the pretensioner is received; and a control section, in a case in which the vibrating unit is to be vibrated, outputting an instruction to vibrate the vibrating unit to the operating section, and, in a case in which the pretensioner is to be operated, outputting an instruction to operate the pretensioner to the operating section.

Vehicle passenger space contact mitigation (e.g., using a computerized tool) is enabled. For example, a system can comprise a memory that stores computer executable components, and a processor that executes the computer executable components stored in the memory, wherein the computer executable components comprise: a calculation component that determines a distance between an occupant of a vehicle and an object of the vehicle, and an impact mitigation component that, based on the distance, facilitates an action determined to mitigate an impact between the occupant and the object.

A control device to be applied to a vehicle equipped with an imaging device and a safety device is configured to, based on moving-object detection information detected from images captured by the imaging device, actuate the safety device for a moving object. In the control device, a control unit is configured to, in response to any of certain information that it is certain that the object is a moving object and uncertain information indicating that it is not certain whether the object is a moving object being acquired as moving-object detection information, actuate the safety device based on a position of the object subjected to detection with the certain information or the uncertain information. An actuation region setting unit is configured to, when the moving-object detection information is the uncertain information, narrow an actuation region as compared to when the moving-object detection information is the certain information.

A method for controlling actuation of an actuatable restraint in response to a vehicle rollover event includes detecting whether the vehicle (12) is being driven off-road. The method also includes determining whether the vehicle (12) is undergoing a roll event (99) that would warrant actuation of the actuatable restraint (20) if the vehicle was being driven on-road. The method further includes actuating the actuatable restraint (20) in response to determining that a roll acceleration (D RATE) of the vehicle (20) indicates that the roll event is continuing. A vehicle safety system (10) includes an actuatable restraint and a controller (50) configured to control actuation of the actuatable restraint according to this method.

A method and system for operating restraint devices in a vehicle during a fast roll event or a slow roll event includes a lateral acceleration sensor and an angular rate sensor. When the angular rate and a vertical acceleration of the vehicle predict a vehicle rollover, the system integrates the lateral acceleration from the lateral acceleration sensor to obtain a roll rate velocity. When the lateral acceleration is greater than a fast lateral acceleration threshold and the roll rate velocity is greater than a fast roll rate velocity threshold, the system provides a fast roll event output. When the lateral acceleration is less than the fast lateral acceleration threshold and greater than a slow lateral acceleration threshold while the roll rate velocity is greater than a slow roll rate velocity threshold, the system provides a slow roll event output. The system operates restraint devices based on the roll event.

Various embodiments relate generally to autonomous vehicles and associated mechanical, electrical and electronic hardware, computer software and systems, and wired and wireless network communications to provide map data for autonomous vehicles. In particular, a method may include accessing subsets of multiple types of sensor data, aligning subsets of sensor data relative to a global coordinate system based on the multiple types of sensor data to form aligned sensor data, and generating datasets of three-dimensional map data. The method further includes detecting a change in data relative to at least two datasets of the three-dimensional map data and applying the change in data to form updated three-dimensional map data. The change in data may be representative of a state change of an environment at which the sensor data is sensed. The state change of the environment may be related to the presence or absences of an object located therein.
