1. A thermal management system for controlling cooling of an engine system during shutdown, the engine system comprising an engine configured to provide power to a working machine, wherein the thermal management system comprises:
a controller;
the controller being configured to receive a signal indicative of an engine shutdown command; the controller being further configured to derive, infer or receive a temperature parameter of the engine system and to determine whether the temperature parameter of the engine system is above a first predetermined threshold;
wherein the controller is configured to signal the progressive reduction of a speed of the engine prior to issuing a signal to shutdown the engine in the event that the first predetermined threshold is exceeded when the engine shutdown command is received, thereby cooling the engine system prior to engine shutdown; and
wherein the progressive reduction of the speed of the engine is a gradual decrease in the speed of the engine over a period of time from a first engine speed above an idle speed to a second engine speed lower than the first engine speed.
