The vehicle includes an internal combustion engine having a crankshaft, a motor generator having an output shaft, a clutch, a water pump, a coolant temperature sensor, and a controller. The clutch is located between the crankshaft and the output shaft. The water pump is configured to pump the coolant in conjunction with rotation of the crankshaft. The coolant temperature sensor is configured to detect a coolant temperature of the internal combustion engine. The clutch is switchable between an engaged state and a disengaged state. The controller includes processing circuitry. When a predetermined condition is satisfied, the processing circuitry is capable of executing an engine stopping process of bringing the clutch into the disengaged state and stopping operation of the internal combustion engine. The predetermined condition includes that the coolant temperature detected by the coolant temperature sensor is equal to or lower than a first temperature.

An apparatus for handling fluid within an at least partially electrically driven vehicle, with a valve device including a valve housing. The valve housing includes at least three two radially arranged port openings and at least one axially arranged port opening for the inflow and/or outflow of fluid, and a valve body which is arranged inside the valve housing and is configured to be rotatable about an axial axis of rotation R. The valve body includes a first connecting channel of arcuate shape for connecting two radially arranged port openings and a second connecting channel of arcuate shape for connecting a radially arranged port opening with an axially arranged port opening. The at least two radially arranged port openings define a base plane B, which is configured orthogonally to the axial axis of rotation R, and the first arcuate connecting channel defines a first connecting channel plane V.
