  • Publication number: 20090256374
    Abstract: Provided is an armrest assembly disposed on an inner door panel of a vehicle. The armrest assembly includes an armrest panel shaped to form the body of the armrest, and a support surface made of flexible skin. The armrest panel is fixed to a predetermined location on the inner door panel, and extends upwardly and away from the inner door panel to a proximal end. The proximal end is spaced apart and opposite the inner door panel to define an cavity. The flexible skin is attached to the proximal end and pulled taut over the cavity and fixed to the inner door panel to form the support surface for receiving the load of a passenger arm. The armrest assembly having the flexible skin for a support surface is able to fold into itself when the vehicle door is subject to a predetermined load, thus presenting no rigid structure posing a threat of being pushed into a passenger under said predetermined load.

  • Publication number: 20090259841
    Abstract: In a vehicle-to-vehicle communication network utilizing PKI security methods to protect communications and in which the PKI encryption utilizes a Certificate Authority having both a private key and a publicly distributed key, a method for allocating multiple certificates for each vehicle which are assigned to each vehicle in the communication network. The method includes the step of assigning a unique secret key k to each vehicle in the communication network. The Certificate Authority then creates a plurality of public key and private key encryption pairs for each vehicle and each encryption pair is associated with an index i. A plurality of certificates are then created with one certificate for each value of the index. A revocation list comprising the secret keys is maintained by the Certificate Authority so that all encryption pairs assigned to a particular vehicle may be revoked by the secret key k corresponding to that vehicle.

  • Publication number: 20090260057
    Abstract: In a vehicle-to-vehicle wireless communication system utilizing certificates to verify trustworthiness of received communications, a method for distributing a list of certificate revocations to vehicles in the communication system. At least one main station transmits a list of certificate revocations to at least one vehicle and the vehicle thereafter transmits the list of certificate revocations to other vehicles in the communication network. Each of the other vehicles in the communication network updates its list of certificate revocations in response to the receipt of the list of certificate revocations from another vehicle in the system. The other vehicles thereafter transmit their updated list of certificate revocations to other vehicles in the system.

  • Publication number: 20090251375
    Abstract: A method for fabricating a microwave horn antenna in which a thermoplastic sacrificial layer is mounted to a thermoplastic horn layer. A heated horn embossing plate having at least one horn shaped embossing element is then moved into the horn layer so that the horn element penetrates through the horn layer and extends partially into the sacrificial layer thus forming a horn opening in the horn layer complementary in shape to the horn element. The horn layer and sacrificial layer are then separated from each other and the horn opening and at least a portion of the back surface of the horn layer is covered with a metal coating. A thermoplastic wave guide layer formed by embossing wave guide channels into the layer is covered with metal and attached to the back side of the horn layer to form the antenna. Alternatively, a portion of the horn and the remaining portion of a microwave channel are formed in both a first and second thermoplastic section.

  • Publication number: 20090236825
    Abstract: A system for assisting the alignment of a hitch pin mounted on the rear of a vehicle with a hitch socket mounted on the front of a trailer. The system includes a camera mounted to the vehicle and positioned to capture an image rearwardly of the vehicle. A video display is contained within the vehicle which displays the image captured by the camera. A processor is also contained in the vehicle which calculates a preferred path of travel of the vehicle to position the hitch pin in alignment with the hitch socket. The processor is programmed to provide instructions to an operator of the vehicle of the required steering to maintain the vehicle on the preferred path of travel. The processor recalculates the preferred path of travel whenever the vehicle veers from the preferred path of travel by a preset threshold.

  • Patent number: 7593796
    Abstract: An apparatus for the determination of engine torque comprises a neural network receiving engine operational data, such as crankshaft rotation data, and providing an output corresponding to engine torque. The neural network may be, for example, a recurrent neural network (RNN) that is configured using training data obtained using a training process. By comparing a determined engine torque with an intended engine torque, for example determined from engine control input values such as throttle position, a useful engine diagnostic is obtained.

  • Publication number: 20090233762
    Abstract: A method for adjusting downshift points of a vehicle transmission to assist vehicle braking in a vehicle having a brake system with a brake master cylinder and a brake pedal for actuating the brake system may comprise determining if the brake pedal is pressed. When the brake pedal is pressed, an intended brake effort may be determined and the actual deceleration of the vehicle may be calculated. A threshold deceleration for the intended brake effort may then be determined and compared to the vehicle deceleration. When the vehicle deceleration is less than the threshold deceleration for the intended braking effort a downshift point of the transmission may be adjusted. Thereafter the transmission may be downshifted using the adjusted downshift point.

  • Publication number: 20090227418
    Abstract: A method for regulating the speed at which an electric vehicle descends a hill includes determining a position of a shift lever and determining if the vehicle accelerator and/or the vehicle brake are depressed. If the vehicle is in either drive or reverse and neither the vehicle accelerator nor the vehicle brake is depressed, a change in the motor speed is determined based on the current motor speed and a reference motor speed. The current braking assist is then adjusted based on the change in the motor speed such that the motor speed, and therefore the speed of the electric vehicle, remains constant as the vehicle descends the hill.

  • Publication number: 20090224896
    Abstract: Provided is a system and method for detecting the presence of an intruder in a vehicle using sensors to measure the change in distance between a portion of the vehicle and the ground. Distance sensors may be placed in a plurality of locations along the vehicle, preferably under the hood where the sensors have a clear line of sight to the ground. A computer is provided to receive the measurements from the sensors to compute a base distance which represents the weight of the vehicle with no intruder. The sensors continue to measure the distance to the ground and the computer subsequently computes a present distance and compares said present distance to said base distance. The computer activates an alarm when the present distance is lesser than the base distance by a predetermined value.
