  • Steering a differential steering machine while commanded to be in neutral
    Patent number: 11148714
    Abstract: A method for steering a machine while commanded to be in neutral, including: sensing that a transmission is in a neutral setting; applying one or more service brakes into a braking mode; ramping off a steering pump on a hydraulic steering system; sensing a steering command; releasing the one or more service brakes from the braking mode in response to sensing the steering command; and ramping on the steering pump on the hydraulic steering system.
    Type: Grant
    Filed: February 4, 2019
    Date of Patent: October 19, 2021
    Assignee: Caterpillar Inc.
    Inventors: Randall T. Anderson, Benjamin D. Miller, Luke R. Sheley, Michael Anthony Berry
  • Transmission control or steering control based on one or more operating inputs associated with a vehicle
    Patent number: 10850736
    Abstract: An example, described herein, involves monitoring an operating input of a vehicle; determining a turning maneuver is to be performed by the vehicle with a decreased turn radius based on the operating input; determining that a transmission of the vehicle is to be downshifted to a low gear to enable the vehicle to perform the turning maneuver; and downshifting the transmission to the low gear.

  • BRAKE CONTROL BASED ON TRANSMISSION SPEED
    Publication number: 20190351904
    Abstract: An example described herein may involve monitoring a transmission speed associated with a transmission of a vehicle; determining a threshold transmission speed for the transmission; determining an amount of braking to be applied by a braking device of the vehicle based on the transmission speed and the threshold transmission speed; and/or automatically causing the braking device to apply the amount of braking to cause the vehicle to travel at a vehicle speed that corresponds to the threshold transmission speed.
