Computer system and method for controlling a vehicle

A vehicle comprising a computer system comprising processing circuitry configured to control a vehicle, the processing circuitry being configured to:

• determine that an expected travelling route of the vehicle comprises a downhill road segment followed by an uphill road segment;
• predict an engine exhaust condition of an engine of the vehicle, wherein the engine exhaust condition is expected to apply while driving the vehicle along the uphill road segment;
• determine a target temperature criterion for an exhaust aftertreatment system of the vehicle based on the predicted engine exhaust condition;
• control the vehicle during the downhill road segment such that a temperature of the exhaust aftertreatment system meets the target temperature criterion at a beginning of the uphill road segment;
• monitor a temperature of the exhaust aftertreatment system during the downhill road segment;
• and
• control the engine to be turned off and decoupled from a driveline of the vehicle in response to detecting that the target temperature criterion is met.

A computer-implemented method for controlling a vehicle, the method comprising:

• determining, by processing circuitry of a computer system, that an expected travelling route of a vehicle comprises a downhill road segment followed by an uphill road segment;
• predicting, by the processing circuitry, an engine exhaust condition of an engine of the vehicle, wherein the engine exhaust condition is expected to apply while driving the vehicle along the uphill road segment;
• determining, by the processing circuitry, a target temperature criterion for an exhaust aftertreatment system of the vehicle based on the predicted engine exhaust condition;
• controlling, by the processing circuitry, the vehicle during the downhill road segment such that a temperature of the exhaust aftertreatment system meets the target temperature criterion at a beginning of the uphill road segment;
• monitoring a temperature of the exhaust aftertreatment system during the downhill road segment;
• and
• controlling the engine to be turned off and decoupled from a driveline of the vehicle in response to detecting that the target temperature criterion is met.
