Publication number: 20200362614Abstract: A vehicle door actuator assembly includes a base plate having a first portion and a second portion, a first gear disposed proximate the first portion of the base plate, a second gear disposed proximate the second portion of the base plate, a third gear connected to the base plate, and a linkage engaging the first, second, and third gears. The base plate of the vehicle door actuator assembly is rotatable between a first position and a second position. As the base plate rotates between the first and second positions, the vehicle door actuator assembly maintains an outer surface of the vehicle door substantially parallel to a longitudinal axis of the vehicle at all points along a travel path of the vehicle door.Type: ApplicationFiled: April 27, 2020Publication date: November 19, 2020Inventors: Brandon Loeb, Johannes Edren

Patent number: 10828955Abstract: A suspension system for controlling movement of a vehicle wheel may include a spring and damper assembly coupling the wheel to the vehicle chassis for movement of the wheel relative to the vehicle chassis. The spring and damper assembly may include a spring coupled to a damper member configured to extend and retract the wheel relative to the vehicle chassis. The suspension system may further include a damper actuator located remotely from the spring and damper assembly and configured to modify an amount of damping and/or wheel extension. The suspension system may also include a spring actuator integrated with the damper actuator and configured to control an amount of deflection of the spring and/or to alter a spring rate. The damper actuator may be provided at a location in the vehicle separated from the spring and damper assembly.Type: GrantFiled: June 29, 2018Date of Patent: November 10, 2020Assignee: Zoox, Inc.Inventors: Johannes Edren, Ahditya Melkote, Phillip Newport Kuys, Andrew James Webb, Paul Choin

Patent number: 10821981Abstract: An over actuated system capable of controlling wheel parameters, such as speed (e.g., by torque and braking), steering angles, caster angles, camber angles, and toe angles, of wheels in an associated vehicle. The system may determine the associated vehicle is in a rollover state and adjust wheel parameters to prevent vehicle rollover. Additionally, the system may determine a driving state and dynamically adjust wheel parameters to optimize driving, including, for example, cornering and parking. Such a system may also dynamically detect wheel misalignment and provide alignment and/or corrective driving solutions. Further, by utilizing degenerate solutions for driving, the system may also estimate tire-surface parameterization data for various road surfaces and make such estimates available for other vehicles via a network.Type: GrantFiled: October 18, 2017Date of Patent: November 3, 2020Assignee: Zoox, Inc.Inventors: Joseph Funke, Johannes Edren, Ali Javidan

Patent number: 10688841Abstract: 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.Type: GrantFiled: July 31, 2017Date of Patent: June 23, 2020Assignee: Zoox, Inc.Inventors: Robert Chen, Matthew Austin Terrel, Nivedita Chandrasekaran, Johannes Edren, Joseph Funke

Publication number: 20200094645Abstract: A suspension system may include a pneumatic spring at each wheel of a vehicle. The suspension system may be configured to determine and achieve a pressure set point in each of the pneumatic springs and a target ride height at each wheel of the vehicle. The pressure set point may be determined based on a load at each of the wheels and the center of gravity of the vehicle, such that upon reaching the pressure set point at each in each of the pneumatic springs, a target load and target ride height may be achieved at each of the wheels of the vehicle. The system may also be used to level the ride height of the vehicle and/or achieve a desired orientation.Type: ApplicationFiled: September 24, 2018Publication date: March 26, 2020Inventors: Johannes Edren, Ahditya Melkote

Publication number: 20190371093Abstract: Systems, methods, and apparatuses described herein are directed to vehicle self-diagnostics. For example, a vehicle can include sensors monitoring vehicle components, for perceiving objects and obstacles in an environment, and for navigating the vehicle to a destination. Data from these and other sensors can be leveraged to determine a behavior associated with the vehicle. Based at least in part on determining the behavior, a vehicle can determine a fault and query one or more information sources associated with the vehicle to diagnose the fault. Based on diagnosing the fault, the vehicle can determine instructions for redressing the fault. The vehicle can diagnose the fault in near-real time, that is, while driving or otherwise in the field.Type: ApplicationFiled: August 15, 2019Publication date: December 5, 2019Inventors: Johannes Edren, Moritz Boecker, Joseph Funke

Patent number: 10486485Abstract: Vehicle ride can be improved using perception based suspension control on a vehicle. A computing system on the vehicle may receive a map of a road surface. The computing system may identify a trajectory of the vehicle relative to the road surface, and determine if a deformation exists in a track of one of the vehicle tires. The deformation may include a depression and/or a raised portion from the road surface. The computing system may calculate an adjustment to make to one or more suspension system components to negate or minimize the effects of the vehicle traveling over the deformation or roughness of the road, and may send an instruction to adjust the suspension components accordingly. Additionally, or alternatively, the computing system may determine that the deformation may be avoidable, in whole or in part, and may cause the vehicle to maneuver around the deformation.Type: GrantFiled: April 19, 2017Date of Patent: November 26, 2019Assignee: Zoox, Inc.Inventors: Jesse Sol Levinson, Johannes Edren, Ali Javidan, Timothy David Kentley-Klay, Joseph Funke

Patent number: 10322724Abstract: Brake force distribution via a combination of mechanical braking and regenerative braking techniques is described. In an example, a brake system of a vehicle can detect a braking action and can cause a first negative force to be distributed across two or more wheel assemblies associated with the vehicle. A control system of the vehicle can send a command to at least a power system of the vehicle to cause the power system to affect a second negative force on a first wheel assembly and a positive force on a second wheel assembly to cause an uneven distribution of brake force between the first wheel assembly and the second wheel assembly. As a result, a combined net braking force is applied to the front wheels—the wheels with the most grip—and a reduced net braking force to is applied to the rear wheels to prevent rear-wheel lock-up.Type: GrantFiled: January 28, 2019Date of Patent: June 18, 2019Assignee: Zoox, Inc.Inventors: Johannes Edren, Moritz Boecker, Ryan O'Leary Flatland
