An airbag device includes a first chamber filled with a gas supplied from a first gas supply part and inflated and deployed in a traveling direction of a vehicle body, a second chamber that is disposed behind the first chamber and able to bring in communication with an inside of the first chamber through a communication section, and a third chamber disposed to cover the communication section and configured to adjust an opening degree of the communication section by being filled with a gas supplied from a second gas supply part and being inflated and deployed.

Systems and methods for autonomous delivery management are disclosed. In various embodiments, the system includes one or more processors and a memory storing instructions which, when executed by the processor(s), cause the autonomous delivery management system to provide a user interface for a customer to enter subscription information, receive subscription information from the user interface where the subscription information includes an item and a time interval for regularly delivering the item to the customer, store the subscription information, determine a handling itinerary for the item that includes delivery of the item in compliance with the time interval, and communicate instructions to an autonomous vehicle based on the handling itinerary.

An apparatus comprising a transceiver, an antenna and a processor. The transceiver may be configured to send/receive data messages to/from a plurality of vehicles. The antenna may be configured to receive signals from GNSS satellites. The processor may be configured to (i) determine a first region based on relative coordinates calculated using the data messages, (ii) determine a second region calculated using the signals received from the GNSS satellites, (iii) determine whether a pre-determined amount of the first region to the second region overlap and (iv) increase a confidence level of a positional accuracy of the plurality of vehicles if the pre-determined amount of the first region and the second region overlap. One of the vehicles implements one or more automatic responses based on the confidence level of the positional accuracy.

A method and system of diagnosing the integrity of a sealed air tube of a pedestrian protection system of a vehicle is provided. The method provides the sealed air tube having a pressure sensor connected at each end of the air tube. The air tube is constructed and arranged to be located in front fascia of a vehicle. A processor circuit is electrically connected with the pressure sensors and the processor circuit has a Fast Fourier Transform element. Natural frequencies of a frequency spectrum of the air tube are obtained when no leak is known to be present in in the air tube. Signals from the pressure sensors are transformed into the frequency domain with the Fast Fourier Transform element. A leak is determined to be present in the air tube if frequencies other than the natural frequencies exist in the frequency spectrum of the air tube.

A dual direction accident prevention (DDAP) and assistive braking system (ABS) which detects both the risk of a frontal accident and a rear accident and then coordinates braking to prevent both if possible while giving priority to preventing a frontal accident. In the event of an imminent rear collision with an object or vehicle in front of a driver, the system will choose a braking force which minimizes the impact of the rear collision, while determining a safe approach toward the front obstacle. Furthermore, if a vehicle is approaching the driver and an accident is imminent, and there is no further room in front to reduce the effect of the imminent impact, the system prepares the vehicle and driver by bracing for impact by applying emergency brakes, tightening seatbelts, etc.
