Control unit

A controller for a vehicle, said vehicle comprising a wheel axle fluid circuit adapted to feed wheel axle fluid to one or more wheel axles of said vehicle, said vehicle further comprising a propulsion assembly adapted to propel said vehicle, said controller being adapted to:

• on the basis of at least the following:
• information indicative of said propulsion assembly being inactive,
• information indicative of an expected time range until an expected operation start time of said vehicle, and
• information associated with a temperature of said wheel axle fluid,
• determine whether or not a conditioning procedure, during which the temperature of said wheel axle fluid is increased as compared to a present temperature of said wheel axle fluid, should be initiated for said wheel axle fluid;
• wherein said vehicle comprises a wheel axle fluid heat exchanger, said wheel axle fluid circuit being fluidly connected to said wheel axle fluid heat exchanger such that wheel axle fluid passes through said wheel axle fluid heat exchanger when said wheel axle fluid is circulated through said wheel axle fluid circuit, wherein said vehicle further comprises a transmission fluid pump as well as a transmission converter, said transmission fluid pump being adapted to feed transmission fluid to said transmission converter, said transmission converter being arranged in relation to said wheel axle fluid heat exchanger such that transmission fluid leaving said transmission converter can be used as a heat source for said wheel axle fluid heat exchanger, said controller being adapted to:
• in response to determining that said conditioning procedure should be initiated, issue a wheel axle fluid heat exchanger control signal such that the wheel axle fluid heat exchanger adds heat to the wheel axle fluid;
• and
• in response to determining that said conditioning procedure should be initiated, issue a transmission fluid pump control signal to said transmission fluid pump such that said transmission fluid pump feeds transmission fluid to said transmission converter as well as to issue a transmission converter control signal to said transmission converter to assume a transmission converter operating condition in which the temperature of the transmission fluid leaving said transmission converter is higher than the temperature of said transmission fluid entering said transmission converter.

A controller for a vehicle, said vehicle comprising a wheel axle fluid circuit adapted to feed wheel axle fluid to one or more wheel axles of said vehicle, said vehicle further comprising a propulsion assembly adapted to propel said vehicle, said controller being adapted to:

• on the basis of at least the following:
• information indicative of said propulsion assembly being inactive,
• information indicative of an expected time range until an expected operation start time of said vehicle, and
• information associated with a temperature of said wheel axle fluid,
• determine whether or not a conditioning procedure, during which the temperature of said wheel axle fluid is increased as compared to a present temperature of said wheel axle fluid, should be initiated for said wheel axle fluid;
• wherein said wheel axle fluid circuit comprises a wheel axle fluid pump arrangement adapted to circulate said wheel axle fluid through said wheel axle fluid circuit, wherein said vehicle comprises an implement fluid circuit with an implement fluid pump, said wheel axle fluid pump arrangement comprising a wheel axle fluid motor and a wheel axle fluid pump, said wheel axle fluid motor being mechanically connected to said wheel axle fluid pump, said implement fluid circuit being connected to said wheel axle fluid pump arrangement such that implement fluid in said implement fluid circuit can power said wheel axle fluid motor, said controller being adapted to:
• in response to determining that said conditioning procedure should be initiated, issue a wheel axle fluid pump arrangement control signal to said wheel axle fluid pump arrangement to circulate said wheel axle fluid through said wheel axle fluid circuit to thereby increase the temperature of said wheel axle fluid prior to said expected operation start time of said vehicle;
• and
• in response to determining that said conditioning procedure should be initiated, issue an implement fluid pump control signal such that said implement fluid in said implement fluid circuit powers said wheel axle fluid motor.
