Abstract
Methods, apparatuses, and systems for determining a dynamic shift schedule for a system are provided. A method includes: determining, by a controller, a priority for a system based on data indicative of operation of the system; determining, by the controller, a shift point for the system based on the priority and at least one of a current gear, a current accelerator pedal position (APP), an acceleration vector, or a target gear; and taking, by the controller, an action based on the determined shift point.
Claims20
A method comprising:
- determining, by a controller, a first or a second priority for a transmission shift point for a system from a plurality of priorities based on data indicative of operation of the system, the data comprising at least one of an operation mode of an engine of the system or a temperature of a component of an aftertreatment system of the system, wherein the first priority is determined based on at least one of the operation mode being in a first mode or the temperature of the component being above a first temperature threshold, and wherein the second priority is determined based on at least one of the operation mode being in a second mode or the temperature being below a second temperature threshold;
- determining, by the controller, the transmission shift point for the system based on the determined first or second priority and at least one of a current gear, a current accelerator pedal position (APP), an acceleration vector, or a target gear, wherein the transmission shift point for the first priority is different from the transmission shift point for the second priority;
- and
- taking, by the controller, an action based on the determined transmission shift point.

A system, comprising:
- a controller comprising a processing circuit including at least one processor coupled to at least one memory storing instructions that, when executed by the at least one processor, cause the controller to:
- determine a first or a second priority for a transmission shift point for a system from a plurality of priorities based on data indicative of operation of the system, the data comprising at least one of an operation mode of an engine of the system or a temperature of a component of an aftertreatment system of the system, wherein the first priority is determined based on at least one of the operation mode being in a first mode or the temperature of the component being above a first temperature threshold, and wherein the second priority is determined based on at least one of the operation mode being in a second mode or the temperature being below a second temperature threshold;
- determine the transmission shift point for the system based on the determined first or second priority and at least one of a current gear, a current accelerator pedal position (APP), an acceleration vector, or a target gear, wherein the transmission shift point for the first priority is different from the transmission shift point for the second priority;
- and
- take an action based on the determined transmission shift point.

A non-transitory computer-readable medium storing instructions that, when executed by at least one processor, cause the at least one processor to perform operations comprising:
- determining a first or a second priority for a transmission shift point for a system from a plurality of priorities based on data indicative of operation of the system, the data comprising at least one of an operation mode of an engine of the system or a temperature of a component of an aftertreatment system of the system, wherein the first priority is determined based on at least one of the operation mode being in a first mode or the temperature of the component being above a first temperature threshold, and wherein the second priority is determined based on at least one of the operation mode being in a second mode or the temperature being below a second temperature threshold;
- determining the transmission shift point for the system based on the determined first or second priority and at least one of a current gear, a current accelerator pedal position (APP), an acceleration vector, or a target gear, wherein the transmission shift point for the first priority is different from the transmission shift point for the second priority;
- and
- taking an action based on the determined transmission shift point.
