Patent number: 11068013Abstract: An electronic pedal assembly may include a pedal platform and at least one force sensor configured to sense a force applied to the pedal platform. One or more control devices may be communicatively coupled to the force sensor(s) and configured to determine a throttle output for controlling the throttle condition of the vehicle based at least in part on the force applied to the pedal platform and based at least in part on an operating condition associated with operating the vehicle. In some embodiments, the force sensor(s) may be configured to measure a force distribution on the pedal platform. The control device(s) may monitor the force distribution and adjust an operation of the vehicle based on the force distribution. The operation of the vehicle can include controlling the throttle condition of the vehicle or an operation that is different from controlling the throttle condition of the vehicle.Type: GrantFiled: July 16, 2019Date of Patent: July 20, 2021Assignee: AB Elektronik GmbHInventors: Stefan Rühl, Dirk Neubauer, Roger Möllers

Patent number: 11060882Abstract: Travel data may be gathered and published on a global map for use by various entities. The travel data may be captured by one or more vehicle computing devices, such as those associated with the operation and/or control of a vehicle. The vehicle computing devices may receive input from one or more sensors, and may identify and/or classify an event and/or areas of interest based on the input. The vehicle computing devices may then send travel data to the global map server for publication. Additionally or alternatively, the travel data may be captured by one or more user devices. The user devices may be configured to receive travel data, such as via a user interface, and to send the travel data to the global map server for publication. The global map server may consolidate and publish the travel data on a global map.Type: GrantFiled: June 7, 2019Date of Patent: July 13, 2021Assignee: Zoox, Inc.Inventors: Adriano Di Pietro, James William Vaisey Philbin, Gabriel Thurston Sibley

Patent number: 11022058Abstract: Work vehicle engine control systems operable in enhanced engine protection (EP) modes, and associated methods and program products, include a memory storing a first default power profile having a first profile shape as expressed on a power/speed graph, which plots power output and engine speed along vertical and horizontal axes, respectively. A controller architecture is coupled to the memory and is operable in the enhanced EP mode in which the controller architecture: (i) generates a first dynamically-adjusted power profile by repeatedly fitting the first profile shape beneath a moving EP ceiling as expressed on the power/speed graph; (ii) utilizes the first dynamically-adjusted power profile to determine a power output target (POTAR) corresponding to a current speed of the work vehicle engine; and (iii) schedules the power output of the work vehicle engine in accordance with the power output target (POTAR).Type: GrantFiled: April 20, 2020Date of Patent: June 1, 2021Assignee: DEERE & COMPANYInventor: Scott N.

Patent number: 10994707Abstract: A vehicle pedal sensor assembly for use in a vehicle brake pedal including a base and a pedal arm pivotally mounted to the pedal base. A sensor housing includes a non-contacting pedal position sensor and a contacting pedal force sensor. The sensor housing is mounted to the base of the vehicle brake pedal. A magnet is mounted to the pedal arm. The pedal position sensor senses a change in the magnitude and/or direction of the magnetic field generated by the magnet in response to a change in the position of the pedal arm for determining the position of the pedal arm. A pedal force application member exerts a force against the pedal force sensor in response to the change in the position of the pedal arm for determining the position of the pedal arm. The force sensor may be a piezoelectric element, a load cell, or a strain gauge.Type: GrantFiled: May 11, 2020Date of Patent: May 4, 2021Assignee: CTS CorporationInventors: Steven J.

Patent number: 10906553Abstract: Methods and systems for inhibiting an acceleration event prediction includes determining a current vehicle operating condition. An acceleration event is predicted based on a plurality of stored predictions that match the current vehicle operating condition. A determination is made whether to inhibit the acceleration event prediction. The acceleration event prediction is permitted to modify an acceleration event powertrain control such that a powertrain control occurs. A driver noncompliance with the acceleration event powertrain control is stored as a machine learning data and the current vehicle operating condition is stored as machine learning data upon the driver noncompliance. The stored machine learning data is used to determine whether to inhibit a future acceleration event prediction.Type: GrantFiled: July 30, 2018Date of Patent: February 2, 2021Assignee: Toyota Motor Engineering & Manufactuiring North America, Inc.Inventors: Joshua D.
