  • Patent number: 11498382
    Abstract: In some examples, a vehicle suspension for supporting, at least in part, a sprung mass, includes a damper connected to the sprung mass, the damper including a movable piston. The vehicle suspension further includes an actuator and a controller. The controller may be configured to determine a frequency of motion associated with the sprung mass. When the frequency of motion is below a first frequency threshold, the controller may send a control signal to cause the actuator to apply a deceleration force to the sprung mass. Further, when the frequency of motion associated with the sprung mass exceeds the first frequency threshold, the controller may send a control signal to cause the actuator to apply a compensatory force to the sprung mass. For instance, a magnitude of the compensatory force may be based on a friction force determined for the damper.

  • Patent number: 11148665
    Abstract: Provided are a vehicular motion control device and method such that, even when a vehicle is turning, the target trajectory can be followed while maintaining traveling stability, with a reduced sense of incongruity felt by the driver. This vehicular motion control device is equipped with: a target trajectory acquisition unit that acquires a target trajectory for a vehicle to travel; and a speed control unit that increases or decreases the longitudinal acceleration generated in the vehicle, the longitudinal acceleration being positive in the vehicle travel direction. If the vehicle deviates from the target trajectory during turning, the speed control unit performs longitudinal acceleration control to increase or decrease the longitudinal acceleration.

  • Patent number: 11112252
    Abstract: To localize a vehicle in the given map precisely for autonomous driving, the vehicle needs to compare the sensor perceived environment with the map information accurately. To achieve this, the vehicle may use information received from multiple on-board sensors in combination of GPS and map data. Example implementations described herein are directed to maintaining accuracy of sensor measurements for autonomous vehicles even during sensor failure through a raw data fusion technique and a repopulation of data through a prediction technique based on historical information and statistical method if any of the sensors fail.
