Abstract:
An electric vehicle (HEV/BEV/EV) includes a dynamic traction control (DTC) system configured to perform a DTC process and an electric motor enhanced dynamic wheel torque control by brake (eDWT-B) system configured to perform an eDWT-B process. A controller selects according to a vehicle criterion a combination of the DTC and eDWT-B processes to control a vehicle operation.
Abstract:
Route planning for road vehicles is performed taking into account a ride quality that results from the roadway conditions along road segments on a route. A plurality of vehicles equipped with controlled suspensions calculate ride quality indices as the vehicles move over a plurality of road segments. The plurality of vehicles transmit the ride quality indices tagged with respective geographic coordinates to an aggregating server. The aggregating server determines a composite ride quality index for each road segment. A subscriber generates a route planning request identifying an origin and a destination. At least one potential route is identified between the origin and the destination comprised of selected road segments. A route ride quality index is determined in response to the selected road segments, and the potential route and the route ride quality index are presented to the subscriber for selection.
Abstract:
A vehicle's dynamic handling state, driver inputs to the vehicle, etc. may be examined to determine one or more measures of driver workload. Driver interface tasks may then be delayed and/or prevented from executing based on the driver workload so as to not increase the driver workload. Alternatively, driver interface tasks may be schedule for execution based on the driver workload and caused to execute according to the schedule, for example, to minimize the impact the executing driver interface tasks have on driver workload.
Abstract:
A predictive enhanced maneuverability system providing enhanced timely delivery of vehicle performance selection of chassis, and steering modes for potential predicted safety collisions is disclosed. The primary inputs of the disclosed invention include a determination of the proximity to a preceding vehicle, the density of the surrounding traffic, a forward collision warning alert, and the predictive enhanced maneuverability decision sub-system for vehicle mode selection. The system of the disclosed invention provides a customized vehicle dynamics chassis and steering dynamic mode output, based on a predicted decision about vehicle potential for collision, for improved driver maneuverability and safety. In addition, the disclosed invention provides an improved system and method for incorporating the time dependent headway, forward collision warning alert, and the traffic density for chassis collision-mode embedded decision-making. The predictive enhanced maneuverability decision-module allows vehicle dynamics mode selection to be tailored based on proximity to a potential collision.
Abstract:
A method for controlling a vehicle includes the step of determining if a curb parking operation is feasible for the vehicle. If a curb parking operation is deemed infeasible, an operator of the vehicle is notified that curb parking is infeasible. If a curb parking operation is deemed feasible, actuatable elements of the vehicle are controlled to facilitate the curb parking operation.
Abstract:
The present invention extends to methods, systems, and computer program products for path planning for autonomous moving devices. Aspects of the invention include planning a path for a mobile robot to move autonomously in an environment that includes other static and moving obstacles, such as, for example, other mobile devices and pedestrians, without reference to a prior map of the environment. A planned path for a mobile robot can be determined, adjusted, and adapted using diffusion maps to avoid collisions while making progress towards a global destination. Path planning can include using transition probabilities between grid points to find a feasible path through parts of the environment to make progress towards the global destination. In one aspect, diffusion maps are used in combination with a receding horizon approach, including computing diffusion maps at specified time intervals.
Abstract:
A battery expansion cradle is attachable to an electric scooter (eScooter) handlebar. The battery expansion cradle includes a battery connection terminal disposed on a face of the battery expansion cradle, where the battery connection terminal electrically connects with a power bus of the electric scooter. A battery module is removably attachable to the face of the battery expansion cradle and the back terminal of another battery. The battery module includes a connector electrically coupling the first rechargeable battery to the eScooter power bus, and includes a mobile device holder disposed on a face of the first battery module with holding means for securing a mobile device to the face of the battery module, which may be offset from the center of the external battery to allow for a clear forward view of the scooter using the smartphone's front camera, and the user's face using the rear camera.
Abstract:
A method for controlling a robotic vehicle in a delivery environment includes causing the robotic vehicle to deploy from an autonomous vehicle (AV) at a first AV position in the delivery environment. The method further includes localizing, via a robotic vehicle controller, an initial position within a global reference map using a robot vehicle perception system, receiving, from the AV, a 3-dimensional (3D) augmented map and localizing an updated position in the delivery environment based on the 3D augmented map and the global reference map. The robot vehicle perception system senses obstacle characteristics, and generates a unified 3D augmented map with robot-sensed obstacle characteristics. The method further includes generating a dynamic path plan to a package delivery destination using the unified 3D augmented map, and actuating the robot vehicle to the package delivery destination according to the dynamic path plan.
Abstract:
Systems and methods that allow a smartphone to be used as an imaging device for undercarriage inspection of a moving vehicle are provided. The method may include locating the smartphone on the ground via one or more sensors of the vehicle. The vehicle may generate a path for the vehicle to drive over the smartphone based on the location of the smartphone, and optionally display the path to facilitate manual driving of the vehicle by the driver over the smartphone. Alternatively, the vehicle may self-drive to follow the path. The smartphone may capture image data indicative of the undercarriage of the vehicle, inspect and analyze the image data to identify one or more issues of the undercarriage of the vehicle, and transmit the analyzed image data to the vehicle for display. The driver may confirm the one or more issues and transmit the data to an inspection professional for additional assistance if needed.
Abstract:
Systems and methods are provided herein for managing a transportation device fleet using teleoperation. Teleoperation may be beneficial for performing fleet management tasks such as rebalancing, relocation of devices to charging stations, and/or assisting devices operating autonomously that encounter obstacles and are unable to proceed autonomously.
