  • Patent number: 8335616
    Abstract: A method for predicting potential injury assessment for at least one occupant of a vehicle involved in a crash event and for broadcasting assessment of the occupant to a medical response unit. An occupant seated in each seat of a vehicle is detected. Occupant data is obtained relating to physical characteristics of each occupant seated in the vehicle. A crash event involving the vehicle is detected. Vehicle dynamic data and safety restraint data during the crash event is recorded. The potential injury assessment of each occupant is predicted by an injury assessment processing module based on the vehicle dynamic data and safety restraint data obtained during the crash event and the occupant data of each occupant in the vehicle. The corresponding injury assessment of each occupant of the vehicle is broadcast to a medical response unit.

  • Patent number: 8155853
    Abstract: A system and method for providing mechanical time dilation by pre-braking a vehicle in the event there is a collision threat so as to reduce or eliminate the need for full automatic braking if the collision becomes imminent. The system calculates a time dilation deceleration to either maintain a time to collision at a previous value before the calculation or at a predetermined value. The system also estimates a projected closing speed of the vehicle to the object at a distance that would require full automatic braking to prevent a collision. The system then determines whether the time dilation deceleration is greater than a decelerating threshold and, if so, provides automatic vehicle braking at the threshold until the vehicle comes to a full stop. If the time dilation deceleration is not greater than the threshold, then the system provides automatic braking to decelerate the vehicle at the time dilation deceleration.

  • Publication number: 20120053793
    Abstract: A method and system for recognizing and verifying the identity of a driver and front seat passenger of a vehicle. A vehicle owner uploads profile data for several individuals who may be a driver or passenger to a database in the vehicle. When a driver or passenger enters the vehicle, the system uses the profile data—which can include height, weight, and gender information about the individual—along with vehicle data such as seat position, to identify the driver or passenger from the database. The profile data for the known individual is then used to adjust the position of the seat and other components in the cockpit. The profile data is also used by various safety and convenience systems onboard the vehicle.

  • Publication number: 20120053794
    Abstract: A method and system for automatically adjusting a driver seat, steering wheel, pedals, mirrors, and other components of a vehicle, based on information about the size of the driver. The method uses basic information about the driver's size—including standing height, sitting height, and gender—in a model which estimates all anthropometric data for the driver. The anthropometric data for the driver—including upper and lower arm and leg lengths, torso length, and other dimensions—is used in inverse kinematic calculations to determine optimal positions and orientations for the adjustable components of the vehicle's cockpit. The method then pre-adjusts the components before the driver enters the vehicle, and makes compatible adjustments to the mirrors and other components if the driver adjusts the driver seat.

  • Patent number: 8056427
    Abstract: An adjustable head tool (AHT) is configured for positioning a free motion headform (FMH) having a regulated FMH backoff requirement prior to an impact between the FMH and a target surface having a target point. The AHT has a built-in or a variable backoff angle relative to the position of the target point, and includes a cranial portion and an adjustable facial template. The cranial portion encloses a linkage assembly, and the facial template has one or more facial features. A rotary dial translates the facial template with respect to the cranial portion to maintain the regulated FMH backoff requirement. The cranial portion includes a forehead impact zone having a first set of demarcations, and the rotary dial has a second set of demarcations corresponding to the first set of demarcations. The dial is set so the second set of demarcations matches the first set during positioning of the AHT.

  • Patent number: 7997620
    Abstract: An adaptive load-limiting seat belt buckle presenter includes a plow assembly movable within a tube and connected to the buckle by cables. Movement of the plow assembly presents the buckle at various positions relative to the occupant. The plow assembly has a plurality of plow elements that engage with the tube to plow troughs in the tube when an occupant restraining load moves the plow assembly within the tube. A plow actuator mechanism selects a number of the plurality of plow elements to be engaged or not engaged with the tube to thereby adapt the load-limiting capability of the presenter. A controller and various sensors cooperate to operate an adjusting motor for translating the plow assembly within the tube to present the buckle at a desired position and to also operate a rotary actuator to select the number of plow elements that will be engaged or not engaged.

  • Patent number: 7996133
    Abstract: An algorithm that is part of a collision preparation system that provides selective and limited vehicle braking to avoid undesirable intrusive high-G braking while still giving the system adequate time to activate collision mitigation devices on the vehicle before impact with an object. If a predicted time to collision between the vehicle and the object is less than a required time to collision, which is determined by how much time is necessary for a certain collision mitigation device to be activated, the algorithm calculates a time dilation deceleration. The system causes the vehicle to automatically brake to decelerate the vehicle at the time dilation deceleration until the time dilation deceleration reaches a predetermined decelerating threshold so that more time is available for the collision preparation system to determine whether to activate the collision mitigation device.

  • Patent number: 7866696
    Abstract: A seat assembly for a vehicle includes a lower seat portion and a seatback portion. The seatback portion is selectively movable to vary the reclination angle of the seatback portion. The seat assembly is configured so that a first part of the lower seat portion rises relative to a second part of the lower seat portion so that the lower seat portion acts as an occupant restraint when a predetermined condition exists. Exemplary predetermined conditions include the reclination angle changing, the reclination angle exceeding a predetermined amount, and conditions indicative of an elevated risk of vehicle impact.

  • Patent number: 7735908
    Abstract: An energy-absorbing hood assembly for a vehicle includes upper and lower layers and a middle panel. The upper and lower layers have first and second interface surfaces, respectively. The middle panel has opposing first and second surfaces defining a corrugated profile having a plurality of bonding surfaces, the bonding surfaces being attached to the first and second interface surfaces to thereby define a plurality of laterally oriented channels. The corrugated profile further defines a height and wavelength along a substantial portion of the hood assembly, each being configured to be variably tunable to provide different predetermined levels of absorption and attenuation of kinetic energy imparted to the hood assembly by objects upon impact therebetween. Preferably, the hood assembly also includes an upper hood panel having an inner surface secured to the upper layer. Ideally, the corrugated profile is a trapezoidal waveform profile.

  • Publication number: 20100121535
    Abstract: A system and method for classifying the optimization of safety features on a vehicle for a driver of the vehicle based on the height and mass of the driver. The method includes determining a number of basic driver sizes based on driver height and mass and determining a driver's seat position for each basic driver height. The method also identifies a set of tunable design variables that are used to adjust the safety features of the vehicle and performs design optimization analysis to identify an optimal design for the vehicle safety features for each of the basic driver sizes. The method then identifies the design from the optimal designs that provides the best performance for randomly selected reference drivers and classifies all drivers into a predetermined number of classifications where each classification represents a particular optimal design.
