  • Patent number: 11231292
    Abstract: Aspects of the disclosure relate generally to generating and providing route options for an autonomous vehicle. For example, a user may identify a destination, and in response the vehicle's computer may provide routing options to the user. The routing options may be based on typical navigating considerations such as the total travel time, travel distance, fuel economy, etc. Each routing option may include not only an estimated total time, but also information regarding whether and which portions of the route may be maneuvered under the control of the vehicle alone (fully autonomous), a combination of the vehicle and the driver (semiautonomous), or the driver alone.

  • Patent number: 11230318
    Abstract: A steering control apparatus for a steering system includes a controller. The controller sets a limit value to less than or equal to a steering angle limit value, the limit value being an upper limit of an absolute value of a torque command value, and controls a motor such that a motor torque follows the torque command. When the absolute value of a rotation angle of a rotary shaft exceeds a steering angle threshold, the controller computes a damping control amount such that the damping control amount increases with an increase in an excess of an angular velocity of the rotary shaft over a first upper limit angular velocity. The controller computes the torque command value based on a value obtained by combining the basic command value and the damping control amount such that an absolute value of the basic command value is reduced.

  • Patent number: 11192469
    Abstract: A vehicle seat can be configured to selectively provide support to a vehicle occupant in conditions when lateral acceleration is experienced. An actuator can be located within the vehicle seat. When activated, the actuator cause a portion of the seat to morph into an activated configuration. The actuator can be activated based on vehicle speed, steering angle, and/or lateral acceleration. The actuator can include a bladder containing a dielectric fluid. A first and second conductor can be operatively positioned on opposite portions of the bladder. When electrical energy is supplied to the first and second conductors, they can have opposite charges. As a result, the first and second conductors can be electrostatically attracted toward each other to cause at least a portion of the dielectric fluid to be displaced to an outer peripheral region of the bladder, which bulges as a result and increases an overall height of the actuator.
