Patent number: 10794477Abstract: A method for operating a pneumatic actuating system of a transmission. The actuating system has an air reservoir at a first pressure. The reservoir couples an actuating space of the actuating system which is at a second pressure, and the actuating space couples, via control valves, shifting cylinders. When conducting a transmission gearshift, an air mass delivered to the active shifting cylinders via corresponding control valves, and an air mass sum including a nominal air mass in the active cylinders required for accomplishing the gearshift and an actual basic leakage from the activated shifting cylinder are determined. A defect leak in the pneumatic actuating system is recognized, if the air mass delivered to the active shifting cylinders is larger than the air mass sum. If a defect leak is recognized, the control valves coupling the actuating space and the shifting cylinders are shut off for a period of time.Type: GrantFiled: November 17, 2017Date of Patent: October 6, 2020Assignee: ZF FRIEDRICHSHAFEN AGInventors: Alain Tierry Chamaken Kamde, Wilhelm Moser

A rigid base of the light source may be flush with the bottom exterior surface around the cavity. The cavity may be concave inward toward a center of the hollow container. A fluid level sensor switch may protrude through a bottom wall of the hollow container to sense a fluid level in the hollow container. A circuit connected to the fluid level sensor switch and the light source may be wired to cause the light source to blink when the fluid level sensor switch detects a predetermined fluid level within the hollow container and a hood switch detects an open vehicle hood. A hole in a top exterior surface may have a cap and facilitate addition or removal of a liquid to the hollow container.Type: ApplicationFiled: March 18, 2010Publication date: September 22, 2011Applicant: DENSO INTERNATIONAL AMERICA, INC.Inventor: Dwayne Taylor

Publication number: 20110148618Abstract: An accelerator opening determining unit determines whether an accelerator opening achieved through an accelerator operation by a driver of a vehicle exceeds an upper limit value thereof. A travel distance adding-up unit adds up a travel distance within accelerator-opening upper limit value when the accelerator opening is not determined to exceed the upper limit value. When the accelerator opening is determined to exceed the upper limit value, the travel distance adding-up unit adds up a travel distance exceeding accelerator-opening upper limit value. A fuel-saving driving rating unit rates the driving of the driver based on each added-up value added up by the travel distance adding-up unit.Type: ApplicationFiled: July 30, 2009Publication date: June 23, 2011Applicants: FUJITSU TEN LIMITED, TOYOTA JIDOSHA KABUSHIKI KAISHA, AISIN AW CO., LTD.Inventors: Satoshi Harumoto, Kouei Kiyo, Shojiro Takeuchi, Naoki Miura, Masaki Nakamura, Hiroaki Sugiura, Yoshio Yamatani, Junichi Nonomura

Patent number: 7877198Abstract: A system and method of identify fuel savings opportunity in a fleet of vehicles based on a determination of fuel consumption due to modifiable use conditions is described. Modifiable use conditions, such as unauthorized usage, speeding and excessive idling, which represent opportunities for fuel savings are identified and fuel consumption based on the modifiable use conditions is determined. A user-defined statistical metric for the fleet, or a portion of the fleet, can be determined for each of the modifiable use conditions evaluated. Fuel consumption of an individual vehicle, or a group of vehicles, resulting from modifiable use conditions can be compared with a larger group of vehicle, or the fleet, to determine vehicles which correspond to a metric of the fleet. Fleet managers can use this information to modify the use conditions of individual or group of vehicles to provide fuel savings for the fleet.Type: GrantFiled: January 23, 2006Date of Patent: January 25, 2011Assignee: General Electric CompanyInventors: Stephen Tenzer, Benjamin J.

Publication number: 20100207754Abstract: RFID and sensor assemblies for vehicles in which an interrogator transmits RF signals and receives responsive RF signals from the RFID assemblies. Each RFID assembly includes a sensor and an RFID switch which receives an RF signal from the interrogator and upon receipt of a signal containing its identification, enables transmission of a signal from the sensor from which a property being monitored by the sensor is determinable. The sensor may be a SAW sensor which modifies a received wave as a function of the property being monitored by the sensor and thus transmits a modified wave. Each RFID assembly may include an antenna arranged to receive signals from and provide signals to the interrogator. The RFID switch is arranged to connect or disconnect the sensor from a circuit dependent on whether the antenna receives a particular signal associated with the RFID assembly.Type: ApplicationFiled: August 1, 2006Publication date: August 19, 2010Applicant: Automotive Technologies International, Inc.Inventors: Oleksandr T.
