  • Patent number: 10166980
    Abstract: A vehicle having a drivetrain is controlled based on a difference between a torque transmitted by the drivetrain when the vehicle has constant non-zero speed and the torque transmitted by the drivetrain when the vehicle is accelerating. The drivetrain torque may be measured by a drivetrain torque sensor. The effective vehicle mass is computed from the torque difference. The computed mass of the vehicle is used to adjust the activation of a collision warning system or a collision avoidance system. A method of operating a vehicle where the activation of a collision avoidance system is adjusted based on a difference between a torque transmitted by a drivetrain when the vehicle has constant non-zero speed and the torque transmitted by the drivetrain when the vehicle is accelerating is disclosed. The torque difference is used to compute a vehicle mass that is used to adjust a collision warning distance.

  • Publication number: 20180201256
    Abstract: Method and apparatus are disclosed for autonomous parking of vehicles in perpendicular parking spots. An example vehicle includes a front corner, a camera, and an autonomous vehicle parker. The autonomous vehicle parker is to detect, via the camera, a perpendicular parking spot and an outer boundary of the perpendicular parking spot, determine a linear parking path located within the perpendicular parking spot and based on the outer boundary, and autonomously turn into the perpendicular parking spot such that the front corner travels along the linear parking path.

  • Patent number: 10000103
    Abstract: A method of controlling a vehicle active suspension system may include, in response to an object being detected forward of the vehicle and a vehicle speed exceeding a threshold, identifying an object classification associated with the object. The method may further include actuating the active suspension system to induce a vibration signature in the vehicle based on the object classification such that a different identified object classification corresponds to a different vibration signature.

  • Patent number: 9975391
    Abstract: Arrangements (e.g., method, apparatus, computer-readable non-transitory media embodying a program) for compensating for understeer or oversteer behavior in a vehicle having a fully active suspension, including: determining whether an understeer or oversteer condition exists; determining a compensation torque needed to correct the understeer or oversteer condition; and generating the compensation torque by using the fully active suspension to shift tire loads between tires.

  • Patent number: 9945300
    Abstract: A method of operating a vehicle includes measuring a transmission output torque, measuring impeller and turbine speeds, estimating a transmission component torque, and adjusting an engine torque to avoid overstressing a transmission component such as a gear. The method does not rely on an accurate estimate of engine torque. Furthermore, the method does not rely on a fixed transmission torque rating in each gear ratio.

  • Patent number: 9841765
    Abstract: Systems and methods for curb detection for parking are disclosed. An example vehicle parking assist system includes a processor and memory. An example program stored in the memory is configured to move a vehicle using a set of maneuvers to park the vehicle in a parking space based on an estimated location of a curb. The example program is also configured to compare a first yaw rate to a reference yaw rate to detect when the vehicle contacts the curb. Additionally, the example program is configured to move the vehicle using an adjusted set of maneuvers based on an actual location of the curb.

  • Patent number: 9709164
    Abstract: A method of operating a transmission includes measuring an output torque, estimating a gearbox input torque using a model, and estimating gearbox component torques based on a detailed gearbox model. The model used to estimate the input torque varies depending on whether a torque converter is locked, open, or slipping. In some operating conditions, multiple estimates are available for gearbox input torque, impeller torque, or shift element torque in which case the models are adapted. When an estimated component torque is outside an expected range, a warning flag is raised and diagnostic data is saved. When an estimated torque approaches or exceeds a torque limit, the input torque command may be reduced to prevent component damage. A warning flag may also be raised and diagnostic data saved in response to a model parameter being adapted to a value outside of a predetermined range.
