Abstract: A vehicle having a control system to utilize a movable suspension to increase sensor coverage. The control system can detect an object of interest that is partially, or completely, outside the field of view of one or more sensors on the vehicle. The system can then use the movable suspension to raise one portion of the vehicle and/or lower another portion of the vehicle to bring the object of interest at least partially into the field of view of the sensor, increasing the effective field of view of the sensor. When an object of interest is determined to be significant (e.g., a traffic or street sign), the system can attempt to bring the object of interest into view of the sensor by tilting the vehicle. The system can use different tilt rates and/or tilt angles depending on whether the vehicle is occupied or not.

Abstract: This disclosure describes methods, apparatuses, and systems for network training and testing for evaluating hardware characteristics and for hardware selection. For example, a sensor can capture a dataset, which may be transformed into a plurality of modified datasets to simulate changes to hardware. Each of the plurality of modified datasets may be used to individually train an untrained neural network, thereby producing a plurality of trained neural networks. In order to evaluate the trained neural networks, each neural network can be used to ingest an evaluation dataset to perform a variety of tasks, such as identifying various objects within the dataset. A performance of each neural network can be determined and compared. A performance curve can be determined for each characteristic under review, facilitating a selection of one or more hardware components and/or configurations.
