Abstract: A two-terminal ferroelectric perovskite diode comprises a region of ferroelectric perovskite material positioned adjacent to a region of n-type doped perovskite semiconductor material. Asserting a positive voltage across the diode can cause the polarization of the ferroelectric perovskite material to be set in a first direction that causes the diode to be placed in a low resistance state due to the formation of an accumulation region in the perovskite semiconductor material at the ferroelectric perovskite-perovskite semiconductor boundary. Asserting a negative voltage across the diode can cause the polarization of the ferroelectric perovskite material to be set in a second direction that causes the diode to be placed in a high resistance state due to the formation of a depletion region in the perovskite semiconductor material at the ferroelectric perovskite-perovskite semiconductor material. These non-volatile low and high resistance states enable the diode to be used as a non-volatile memory element.

Abstract: A method for controlling operation of a motor vehicle includes an electronic controller receiving, e.g., from a vehicle-mounted sensor array, sensor data with dynamics information for a target vehicle and, using the received sensor data, predicting a lane assignment for the target vehicle on a road segment proximate the host vehicle. The electronic controller also receives map data with roadway information for the road segment; the controller fuses the sensor and map data to construct a polynomial overlay for a host lane of the road segment across which travels the host vehicle. A piecewise linearized road map of the host lane is constructed and combined with the predicted lane assignment and polynomial overlay to calculate a lane assignment for the target vehicle. The controller then transmits one or more command signals to a resident vehicle system to execute one or more control operations using the target vehicle's calculated lane assignment.

Abstract: Methods and systems of controlling a vehicle. The methods and systems include switching to a second processor executed mode in response to determining that a range of perception information extends to a range end point that is closer to the vehicle than a first Look Ahead (LA) point. In the second processor executed mode: a motion planner requests a lateral controller to provide a closer LA point relative to the vehicle. The lateral controller determines the closer LA point and sends the closer LA point to the motion planner. The lateral controller generates control commands for an EPS system based on an error between a desired trajectory and an actual trajectory at the closer LA point. The motion planner generates the desired trajectory based on perception data and the closer LA point.
