Electronic Traction Control System
US Patent:
6631320, Oct 7, 2003
Filed:
Nov 27, 2002
Appl. No.:
10/305619

Assignee:
Caterpillar Inc - Peoria IL
International Classification:
B60K 2816
US Classification:
701 83, 180197, 180235, 180244
Abstract:
An articulated work machine has a front frame and a rear frame connected for pivotal movement therebetween for steering the machine by an articulation joint. Each of the front and rear frames has two driven wheels, spaced laterally, each having a brake associated therewith. As the machine articulates during steering, one or more of the wheels may lose traction and slip. An electronic traction control system receives measured wheel speed signals and an articulation angle signal, calculates a desired wheel speed responsive to the wheel speed and articulation angle signals, and selectively applies the brakes until the measured wheel speed is equal to the desired wheel speed.
Apparatus And Method For Varying Brake Response Of A Vehicle
US Patent:
7416265, Aug 26, 2008
Filed:
Nov 26, 2002
Appl. No.:
10/304340
Inventors:
Bradford J. Holt - Peoria IL, US
Jeffrey E. Jensen - Naperville IL, US
Jeffrey E. Jensen - Naperville IL, US
Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
B60T 8/32
US Classification:
303191, 477 92
Abstract:
A vehicle has a brake operator device adapted to travel in a range of brake operator device positions and produce a brake input signal, and a transmission adapted to produce a transmission gear signal. An electronic control module receives the brake input signal and the transmission gear signal and responsively controls engine braking, brake engagement, and/or a transmission downshift. The engine, brakes, and transmission are controlled differently responsive to the brake operator device position depending upon the transmission being in a higher or lower gear. In addition, braking is controlled during a downshift to avoid jerk.
Method For Controlling A Variable-Speed Engine

International Classification:
F02D 41/08, B60W 10/18, H02J 7/00
US Classification:
12333914, 477203, 477183, 320137
Abstract:
A method for controlling a variable-speed engine of a machine is provided. The machine may include a park-brake. The method may include receiving a signal indicating an engagement status of the park-brake. The method may also include operating the variable-speed engine at a first idle speed. Additionally, the method may include operating the variable-speed engine at a second idle speed, lower than the first idle speed, only if the signal indicates that the park-brake is engaged.
Parking And Service Brake Control System For A Vehicle
US Patent:

Filed:
Sep 6, 2002

Assignee:
Caterpillar Inc. - Peoria IL
International Classification:
B60T 13/74
US Classification:
303 3, 701 70, 303 15, 303 20
Abstract:
A vehicle includes at least one wheel, a parking brake associated with the at least one wheel and a service brake associated with the at least one wheel, and a braking control system. The braking control system interprets operator on/off commands to the parking brake. The service brakes are actuated instead of or in addition to the parking brake when a parking brake application is ordered and the vehicle speed falls outside a preferred vehicle speed range. If the vehicle is stopped and the parking brake is engaged, the parking brake is not disengaged responsive to an operator command until the service brake condition is within a preferred ready range.
