The method may include comparing a driver's required acceleration/deceleration with a current acceleration/deceleration of the vehicle, determining that a failure has occurred in the brake system of the vehicle when the driver's required acceleration/deceleration is different from the current acceleration/deceleration of the vehicle and comparing a driver's required braking torque with a regenerative braking maximum torque, and determining that the failure does not occur in the brake system of the vehicle when the driver's required acceleration/deceleration is substantially equal to the current acceleration/deceleration of the vehicle.Type: ApplicationFiled: December 11, 2013Publication date: October 30, 2014Applicants: Research & Business Foundation SungKyunKwan University, Hyundai Motor CompanyInventors: In Su KIM, Jong Yun Jeong, Dong Yoon Hyun, Ji Weon Ko, Hyun Soo Kim

Publication number: 20140309850Abstract: A method of calculating payload material weight is executable by an electronic controller of a machine and includes steps of determining a first force on first front and rear struts of the machine in an unloaded condition of the machine, and adjusting the first force based on at least one of an unloaded front strut friction force and an unloaded rear strut friction force to define an unloaded weight. The method also includes steps of determining a second force on the first front and rear struts in a loaded condition of the machine, and adjusting the second force based on at least one of a loaded front strut friction force and a loaded rear strut friction force to define a loaded weight. A payload material weight is calculated by the method based on a difference between the loaded weight and the unloaded weight.Type: ApplicationFiled: April 15, 2013Publication date: October 16, 2014Applicant: Caterpillar Inc.Inventor: Magomed Gabibulayev

Publication number: 20140288766Abstract: A monitoring unit for vehicle monitoring comprising a receiving module configured to receive data from an OBD, wherein the data is associated with a plurality of jerks detected by a 3-axis accelerometer. The monitoring unit comprises an analytics module configured to compare an intensity of each jerk of the plurality of jerks to a predefined jerk threshold and capture high intensity jerks from the plurality of jerks. The high intensity jerks have intensity equal to or more than the predefined jerk threshold. The method further comprises determining an elapsed time for each of the high intensity jerks. The elapsed time for each of the high intensity jerks is compared to a predefined time threshold. Further it is determined whether an analysis on the high intensity jerks is to be performed at the vehicle or at a server located remotely.Type: ApplicationFiled: February 18, 2014Publication date: September 25, 2014Applicant: Tata Consultancy Services LimitedInventors: Tapas Chakravarty, Avik Ghose, Balamuralidhar Purushothaman, Arpan Pal, Arijit Chowdhary

Patent number: 8831821Abstract: An inhibit path diagnostic system includes a first control module. The first control module includes a message output and transmits a first message from the message output to a controller area network (CAN) via a message transmission path. An inhibit path circuit includes the message transmission path. A second control module transmits a disable control signal to the inhibit path circuit to disable the message transmission path. The first control module transmits a second message from the message output subsequent to and based on the transmitting of the disable control signal. At least one of the first control module and the second control module detects a fault of the inhibit path circuit subsequent to the transmitting of the second message and based on a feedback signal from the CAN.Type: GrantFiled: March 21, 2011Date of Patent: September 9, 2014Inventors: Aubrey Walter Downs, Jr., Hanne Buur, David Dean Tarby, James Mason Faucett
