Patent number: 11753009Abstract: A reactive pedal algorithm is used to modify an accelerator pedal output (APO)-to-torque conversion to produce more deceleration for the same accelerator pedal position. Modifying the APO-to-torque conversion provides the driver of a vehicle the sensation that the vehicle is resisting approaching closer to a lead vehicle. The APO-to-torque conversion is modified based on a scene determination to classify vehicles as in-lane, neighbor-lane, or on-coming. Lane change assist methods and systems are used to modify the APO-to-torque conversion range based on a lead vehicle, a neighbor vehicle, or both.Type: GrantFiled: April 30, 2021Date of Patent: September 12, 2023Assignee: Nissan North America, Inc.Inventors: Christopher Ostafew, Qizhan Tam, Therese Cypher-Plissart

Patent number: 11752820Abstract: A releasable alignment clip secures a primary leaf spring to one or more secondary leaf springs of a suspension of a vehicle. The releasable alignment clip prevents separation of the primary leaf spring from the secondary leaf spring during normal operation while permitting relative sliding. The releasable alignment clip has a minimum separation force such that in response to a collision forcing a wheel forwardly, the releasable alignment clip deforms and permits separation of the primary leaf spring from the secondary leaf spring to avoid the primary leaf spring from breaking between the alignment clip and a point of attachment to the vehicle. The releasable alignment clip may have a reduced thickness, notches, or one or more perforations to achieve the minimum separation force.Type: GrantFiled: August 31, 2022Date of Patent: September 12, 2023Assignee: Nissan North America, Inc.Inventors: Allison Yard, Matthew Gapinski, Yu Zhang, Jeff Mazur, Mike Bristol

Patent number: 11754174Abstract: The transmission control unit includes a gear ratio abnormality determination unit and a limp home control unit. The gear ratio abnormality determination unit is configured to determine that a gear ratio is abnormal when, during travelling at a predetermined gear position, a difference between an actual gear ratio, which is calculated based on a transmission input shaft rotation speed and a transmission output shaft rotation speed, and a set gear ratio at the predetermined gear position is equal to or greater than a set value.Type: GrantFiled: November 20, 2020Date of Patent: September 12, 2023Assignees: JATCO LTD, NISSAN MOTOR CO., LTD.Inventors: Norihira Amano, Masahiro Hamano
