Vehicle (10), comprising: a controller (40) programmed to operate the engine (14) and an electric machine (20) to supply energy to a low-voltage battery (26) and a high-voltage battery (28) at respective rates based on a target engine torque and a temperature of the engine (14) or the electric machine (20) when an engine (14) is operating in response to a remote start request and in response to exhaust gas sensor data indicating closed-loop engine operation.

A controller may cause, in a lubrication oil warm-up mode of a transmission, the transmission to operate in a stall mode that transfers heat to transmission oil for the transmission. The transmission oil may be diverted to a lubrication oil heater to heat the lubrication oil using the transmission oil. The controller may cause the transmission to disengage the stall mode and to engage a park mode, to pause the lubrication oil warm-up mode. The controller may cause the transmission to operate in the stall mode, to resume the lubrication oil warm-up mode, after the pause duration.

The present disclosure provides a cooling system for a hybrid vehicle having an engine and electrical components. The system includes a cooling module having a cooling fan; an engine cooling device having a first line connected to the cooling module and the engine, a first coolant flowing through the first line; an intercooler; an electrical component cooling device having a water pump and a second line connected to the cooling module, the electrical components, and the water pump, a second coolant flowing through the second line; and a controller for controlling operation of the cooling fan and the water pump. The intercooler circulates the second coolant and is disposed in series with the electrical components. Based on a flow direction of the second coolant, the electrical component cooling device includes a bypass line connected to the second line downstream of the cooling module and the second line upstream of the intercooler.

A method (100) of operating a cooling system (1, 1') of a vehicle (2) is disclosed. The cooling system (1, 1') comprises a first and a second coolant circuit (6, 8). The first coolant circuit (6) comprises a first coolant pump (10), a conduit section (12) connected to a pump inlet (10') of the first coolant pump (10), a primer conduit (18), a filling point (75), and a conduit portion (p6) located between the filling point (75) and the pump inlet (10'), wherein the conduit portion (p6) is arranged below the pump inlet (10'). The method (100) comprises the steps of initiating (110) a supply of coolant from the second coolant circuit (8) to the conduit section (12) via the primer conduit (18) during standstill of the first coolant pump (10), and then initiating (120) operation of the first coolant pump (10). The present disclosure further relates to a computer program, a computer-readable medium (200), a control arrangement (21), a cooling system (1, 1'), and a vehicle (2).
