摘要:
A method of operating a restraint system includes classifying a collision into a collision classification, generating a protruding contact sensor output and deploying the restraint system in response to the contact sensor output and the output classification. The method may also use a pre-crash sensor with or without classification and deploy the restraint system in response to the pre-crash sensor signal and the protruding contact sensor signal.

A system and method for performing side impact sensing in a vehicle including at least one side impact zone is provided. The system comprises a controller and at least one crash signature sensor. The controller is configured to deploy one or more safety restraints in response to at least one crash signature signal. The one crash signature sensor is positioned in the side impact zone. The crash signature sensor is configured to detect an impact with an object at the side impact zone. The crash signature sensor is further configured to generate the crash signature signal which corresponds to measured structural impact energy of the vehicle in the side impact zone deformed by the impact at frequencies above 2 kHz.

摘要:
An inflatable member, or deflector, is attached to the frame of the vehicle. The deflector in the expanded condition at least partially fills a space defined by a bumper beam, a portion of the frame, a front tire and a portion of the vehicle body. A sensor provides a signal to a controller to actuate an inflator. The sensor may be a contact sensor, such as an accelerometer or an electro-resistive sensor, or the sensor may be a predictive sensor, such as a radar sensor or a machine vision sensor.

A system includes a vehicle computing processor. The processor is configured to, through wireless communication with a phone, and after determining that a vehicle engine is not running, request and receive motion sensor data from the phone. The processor is further configured to determine if a phone is moving with a driver based on the motion sensor data. Also, the processor is configured to alert the driver if the phone is not moving with the driver.
摘要:
A system and a method for protecting the occupant of a vehicle during a side-impact detects an approaching vehicle and identifies a collision threat. A collision threat level is assessed based on a set of parameters, and when the collision threat exceeds a pre-determined collision threat threshold level, the system unlatches the occupant's door, pushes it a few centimeters outwards, and locks it in that position. Pressure sensors and accelerometers disposed at suitable locations on the sides of the vehicle, provide crash signals to a Restraint Control Module (RCM). When the crash signals exceed a certain threshold, the RCM commands an airbag deployment module to deploy the airbag between the occupant and the door. Since the door is pushed outwards, an extra pre-crush space is created between the occupant and the door, which allows the use of larger and softer side airbags to provide enhanced protection to the vehicle occupants.

A non-contact RFID reader reads a code contained on an RFID tag carried by a driver of a vehicle. The code is assigned to a specific individual expected to operate the vehicle. An electronic module in the vehicle contains a data file uniquely associated with the code, and the data file contains physical characteristics of the driver that may be pertinent to proper functioning of safety systems of the vehicle, such as weight, height, age, and sex. Performance parameters of restraints and/or other safety systems, such as an airbag associated with the driver's seating position are adapted in accordance with the physical characteristics in the data file. The RFID reader may read multiple tags on board the vehicle, so that restraints for multiple seating positions in addition to the driver's seat may be adapted to the individual occupying those positions.
摘要:
A system and method for activating a safety system when a vehicle may be involved in a spin, roll, and/or a spin-to-roll condition. The system and method include determining a side slip angle of the vehicle using the arctangent of the ratio of a lateral and longitudinal velocity. The system and method also include receiving a roll rate signal and determining a roll angle using the roll rate signal. The system and method also include determining a roll warning threshold that is a function of a relationship between the roll rate signal and the roll angle. Lastly, the system and method include activating the safety system when a side slip angle threshold and/or the roll warning threshold are exceeded.
