Abstract: Systems and methods for basis path generation are provided. In particular, a computing system can obtain a target nominal path. The computing system can determine a current pose for an autonomous vehicle. The computing system can determine, based at least in part on the current pose of the autonomous vehicle and the target nominal path, a lane change region. The computing system can determine one or more merge points on the target nominal path. The computing system can, for each respective merge point in the one or more merge points, generate a candidate basis path from the current pose of the autonomous vehicle to the respective merge point. The computing system can generate a suitability classification for each candidate basis path. The computing system can select one or more candidate basis paths based on the suitability classification for each respective candidate basis path in the plurality of candidate basis paths.

Abstract: An autonomous vehicle includes an array of sensors, a processor, and a switch. The array of sensors generate sensor data related to one or more objects in an external environment of the autonomous vehicle and the processor determines an environmental context. The switch transfers the sensor data from the array of sensors to the processor, where the switch is configured to: (a) receive first sensor data from a first sensor group of the array of sensors; (b) receive second sensor data from a second sensor group of the array of sensors; (c) determine an order of transmission of the first sensor data over the second sensor data in response to the environmental context; and (d) transmit the first sensor data to the processor prior to transmitting the second sensor data based on the order of transmission.

Abstract: An autonomous can include one or more configurable passenger seats to accommodate a plurality of different seating configurations. For instance, the one or more passenger seats can include a passenger seat defining a seating orientation. The passenger seat can be configurable in a first configuration in which the seating orientation is directed towards a forward end of the autonomous vehicle and a second configuration in which the seating orientation is directed towards a rear end of the autonomous vehicle. The passenger seat can include a seatback rotatable about a pivot point on a base of the passenger seat to switch between the first configuration and the second configuration. Alternatively, or additionally, the autonomous vehicle can include a door assembly pivotably fixed to a vehicle body of the autonomous vehicle such that a swept path of the door assembly when moving between an open position and a closed position is reduced.
