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.
Claims16
A vehicle controller, comprising:
- one or more processors to:
- monitor a first operating input of a vehicle corresponding to a steering input;
- monitor a second operating input corresponding to an engine deceleration input;
- determine a turning maneuver is to be performed by the vehicle with a decreased turn radius based on the steering input and the engine deceleration input;
- determine that a transmission of the vehicle is to be downshifted to a low gear to enable the vehicle to perform the turning maneuver;
- and
- downshift the transmission to the low gear.
4 more elements
A system of a vehicle comprising:
- a steering input mechanism;
- a powershift transmission with at least two discrete gear ratios;
- a hydraulic motor;
- and
- a vehicle controller to:
- receive an operating input of the vehicle from the steering input mechanism;
- determine a turning maneuver is to be performed by the vehicle with decreased turn radius based on the operating input;
- determine that the powershift transmission of the vehicle is to be downshifted to a lower gear to enable the vehicle to perform the turning maneuver;
- automatically downshift the transmission to the lower gear;
- and
- adjust a steering output, associated with the hydraulic motor of the vehicle, based on downshifting the powershift transmission to the lower gear and the operating input, to cause the vehicle to perform the turning maneuver along a desired path.

A method, comprising:
- monitoring, by a vehicle controller, a steering input of a vehicle;
- monitoring, by the vehicle controller, an engine deceleration input of the vehicle;
- determining, by the vehicle controller, a turning maneuver with a decreased turn radius is to be performed by the vehicle based on the steering input and the engine deceleration input;
- determining, by the vehicle controller, that a transmission of the vehicle is to be downshifted to a lower gear to enable the vehicle to perform the turning maneuver;
- downshifting, by the vehicle controller, the transmission to the lower gear;
- and
- adjusting, by the vehicle controller, a steering output, associated with a hydraulic motor of the vehicle, based on downshifting the transmission, to cause the vehicle to perform the turning maneuver along a desired path.
