  • Patent number: 10486699
    Abstract: A vehicle system includes a processor with access to a memory storing instructions executable by the processor. The instructions include determining whether an autonomous host vehicle can traverse an environmental obstacle, and if the autonomous host vehicle can traverse the environmental obstacle, controlling an active suspension system in accordance with the environmental obstacle and controlling the autonomous host vehicle to traverse the environmental obstacle.
    Type: Grant

  • Patent number: 10315481
    Abstract: Systems and method for assigning vehicle suspension dynamics are disclosed. Control signals that correspond to a current driving dynamic of a suspension system of a vehicle are generated. A vehicle state associated with the generated control signals is computed and a non-traditional suspension mode is selected. Based on the computed vehicle state and the selected suspension mode, a suspension height of the vehicle is adjusted.

  • Patent number: 10293653
    Abstract: The present disclosure generally relates to an obstacle avoidance system with active suspensions. The obstacle avoidance system uses one or more active suspensions to lift or jump one or more corresponding wheels over an obstacle in the vehicle's path to avoid contact with the obstacle when the vehicle cannot practically drive over, steer around, or stop before hitting the obstacle.

  • 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: 9340228
    Abstract: A trailer backup assist system for a vehicle reversing a trailer includes a sensor module adapted to attach to the trailer and generate a trailer yaw rate or a trailer speed. The trailer backup assist system also includes a vehicle sensor system that generates a vehicle yaw rate and a vehicle speed. Further, the trailer backup assist system includes a controller that estimates a hitch angle based on the trailer yaw rate or the trailer speed and the vehicle yaw rate and the vehicle speed in view of a kinematic relationship between the trailer and the vehicle.

  • Patent number: 9187076
    Abstract: Methods and systems are provided for reducing audible clunks and objectionable drive feel in vehicles including start/stop systems. In one example, a vehicle engine is shutdown during vehicle coasting. The vehicle engine is then restarted, while the vehicle is moving with a torque converter clutch disengaged. A transmission clutch pressure is then adjusted during the restart based on a torque converter output speed relative to a torque converter input speed.
