US 11,613,338 B2 · Modular shift protection algorithm for marine vessel

Abstract

A first method of protecting an engine and a transmission of a marine vessel during gear shifts and a second method of programming one or more Shift Protection Sequences (SPS) are disclosed. The first method includes receiving a Shift Request (SR) and activating a SPS from among a plurality of enabled SPS. The second method includes configuring a Shift Protection Type (SPT); enabling and configuring a plurality of required and SPS variables; and, optionally, enabling and configuring a plurality of optional SPS variables. The SPT may be a Basic Shift Protection (BSP), which includes time-based SPS; or the SPT may be an Advanced Shift Protection (ASP), which includes alternate time-based and operating-variable based SPS. The SPS of the ASP may be incrementally programmed and added to the BSP.

Dependent claims

A method of programming one or more shift protection sequences (SPS) which protect an engine and a transmission of a marine vessel during gear shifts, the method comprising the steps of:

configuring a shift protection type (SPT) to be a basic shift protection (BSP) or an advanced shift protection (ASP), wherein:
if the SPT is configured to be the BSP, by default, a normal shift protection (NSP) and a basic crash reversal (BCR) are enabled;
or
if the SPT is configured to be the ASP, by default, the NSP, the BCR, a slow vessel mode shift protection (SVMSP) and an advanced crash reversal (ACR) are enabled;
and
configuring a plurality of required SPS variables, including:
configuring a maximum engine speed to shift (MESTS);
configuring a shift protection engine speed limit (SPESL);
configuring a shift protection hold time (SPHT);
configuring an acceleration time (AT);
configuring a deceleration time (DT);
and
configuring a neutral hold time (NHT).

A method of protecting an engine and a transmission of a marine vessel during gear shifts, the method comprising the steps of:

receiving a shift request (SR);
and
activating a shift protection sequence (SPS) from among a plurality of enabled SPS;
wherein the plurality of enabled SPS always includes a normal shift protection (NSP) and a basic crash reversal (BCR) which execute time-based shift protection logic;
wherein the plurality of enabled SPS includes a slow vessel mode shift protection (SVMSP) and an advanced crash reversal (ACR) which execute alternate time-based and operating-variable-based shift protection logic.
