Abstract: A control system for a vehicle comprises a controller comprising a processor and a non-transitory computer-readable medium including instructions. The system comprises a transformable knob manipulated between first and second states. The knob comprises a body having a periphery wall arranged to flex between first and second configurations with the first and second states, respectively. The system comprises an output device arranged to change between first and second settings. Manipulation of the transformable knob from the first state to the second state transmits an input signal to the controller and facilitates flexing of the periphery wall from the first configuration to the second configuration. The controller receives the input signal, and the processor compares the input signal to the instructions in the non-transitory computer-readable medium and transmit an output signal to the output device to change the output device from the first setting to the second setting.

Abstract: Rules based semantic map sharding is proposed. A method of handling semantic objects for semantic map sharding makes used of rules to define which semantic objects are to be included in a shard. Hereto, semantic objects are defined in a geographical area to be contained in shard data. For the semantic objects, a set of rules is defined comprising a definition of which semantic objects are to be combined into a shard data entry of the shard data and which semantic objects are to be stored in separate shard data entries.
Abstract: A system for monitoring a battery assembly includes a processing device configured to receive measurement data from a plurality of battery components, and input the measurement data to a battery model configured to determine parametric data. Based on the battery model, the processing device is configured to acquire the parametric data, extract statistical information based on at least one parameter of each battery component, and input the statistical information to a failure identification module that includes a first classifier configured to determine whether the battery assembly is in a failure condition based on the statistical information. The processing device is configured to output a health indicator having a first value indicating that the battery assembly is healthy based on first classifier determining that the battery assembly is in the healthy condition, and a faulty value based on the first classifier determining that the battery assembly is in a failure condition.
Abstract: A power control system comprises a battery system including N battery packs. A plurality of contactors selectively connects N battery packs of a battery system in a first configuration supplying a first voltage level, a second configuration supplying a second voltage level, and a disconnected configuration. M power inverters connect the battery system to M electric machines, respectively. A controller is configured to determine when to transition between the first configuration and the second configuration. The controller is configured to transition between the first configuration and the second configuration by causing one of a positive torque transient and a negative torque transient to be generated by at least one of the M electric machines, transitioning the battery system from one of the first configuration and the second configuration to the disconnected configuration, and transitioning from the disconnected configuration to the other one of the first configuration and the second configuration.

Abstract: An autonomous vehicle (AV) implements a notification system that provides notifications to user devices in nearby vehicles to alert drivers of the nearby vehicles of the AV's planned behavior. The notifications are delivered wirelessly and output by the user device to the drivers. The planned behaviors of the AV may not be conveyed by existing mechanisms, such as turning signals or hazard lights. The AV or the receiving user device may determine when an AV's planned behavior may impact a particular driver, and provide relevant notifications to the driver.
Abstract: An automated driving system (ADS) of an autonomous vehicle includes a communication module, a misbehavior detection module, and a processor. The communication module is configured to receive a vehicle-to-vehicle (V2V) message including source vehicle data and receive a fusion data message including fusion data from a mobile edge computing (MEC) system including a roadside unit (RSU). The source vehicle data includes a source vehicle location. The fusion data is based on RSU sensed data and on vehicle sensed data received at the RSU from at least one vehicle. The misbehavior detection module is configured to determine whether a source vehicle is disposed at the source vehicle location based on the fusion data. The processor is configured to manage performance of the autonomous vehicle in accordance with the source vehicle data based at least in part on the determination. Other embodiments are described and claimed.

The vertically stacked lidar assembly includes a first lidar sensor system configured to spin about an axis and a second lidar sensor system configured to spin about the axis. The first lidar sensor system is vertically stacked above the second lidar sensor system in the vertically stacked lidar assembly. Moreover, the first lidar sensor system and the second lidar sensor system are coaxially aligned. Redundancy is provided by the vertically stacked lidar assembly including the first lidar sensor system and the second lidar sensor system.
Abstract: Various aspects of the subject technology relate to a lidar validation system. The lidar validation system is configured to acquire one or more lidar point clouds from a lidar unit, wherein the lidar unit comprises one or more lasers, and wherein each point cloud is a representation of a scene according to a laser in the lidar unit, the scene comprising a fiducial target. The lidar validation system is configured to generate, based on points in the one or more point clouds, a target cloud that correspond to the fiducial target, perform a rigid body processing to minimize a sum of distances from each point in the target cloud to the fiducial target, and generate lidar validation measurements based on the distances from each point in the target cloud to the fiducial target.

Abstract: A vehicle seat restraint system includes a vehicle seat of a vehicle. The vehicle seat includes a leg-rest supporting lower legs and feet of an occupant of the vehicle seat. An in-vehicle occupant detection system identifies positions of the lower legs and the feet of the occupant. A restraint actuator is connected to the vehicle seat. A safety restraint element is extended by actuation of the restraint actuator from a stowed position proximate to the leg-rest into an engaged position wherein the safety restraint element contacts and restrains the lower legs and the feet of the occupant against the leg-rest, mitigating against occupant knee hyperextension due to leg straightening at an occupant knee joint.
