Abstract
A control arrangement and a method for controlling vehicle speed of a vehicle using a cruise control system are provided. The vehicle comprises a power take-off connected to a powertrain of the vehicle. The method comprises a step of, in response to a determination that the power take-off is subjected to a load, predicting future braking torque resulting from the power take-off load. The method further comprises a step of determining a planned driving strategy for an upcoming road section taking into account the predicted future braking torque. The method further comprises controlling the powertrain in accordance with the planned driving strategy, thereby controlling vehicle speed of the vehicle.
Claims15
A method, performed by a control arrangement, for controlling vehicle speed of a vehicle using a cruise control system, said vehicle comprising a power take-off configured to power an auxiliary power consumer, the power take-off being connected to a powertrain of the vehicle said method comprising:
- in response to a determination that the power take-off is subjected to a load, predicting future braking torque that will be applied to the powertrain by the power take-off during an upcoming road section as a result of the power take-off load;
- determining a planned driving strategy for the upcoming road section, where the strategy takes into account the effects of predicted future braking torque to the powertrain;
- and
- controlling the powertrain of the vehicle in accordance with the planned driving strategy, thereby controlling vehicle speed of the vehicle.
A computer program product stored on a non-transitory computer-readable medium, said computer program product for controlling vehicle speed of a vehicle using a cruise control system, said vehicle comprising a power take-off configured to power an auxiliary power consumer, the power take-off being connected to a powertrain of the vehicle, wherein said computer program product comprising computer instructions to cause one or more computer processors to perform the following operations:
- in response to a determination that the power take-off is subjected to a load, predicting future braking torque that will be applied to the powertrain by the power take-off during an upcoming road section as a result of the power take-off load;
- determining a planned driving strategy for the upcoming road section, where the strategy takes into account the effects of predicted future braking torque to the powertrain;
- and
- controlling the powertrain of the vehicle in accordance with the planned driving strategy, thereby controlling vehicle speed of the vehicle.
A control arrangement configured to control vehicle speed of a vehicle using a cruise control system, said vehicle comprising a power take-off configured to power an auxiliary power consumer, the power take-off being connected to a powertrain of the vehicle, wherein the control arrangement is configured to:
- in response to a determination that the power take-off is subjected to a load, predict future braking torque that will be applied to the powertrain by the power take-off during an upcoming road section as a result of the power take-off load;
- determine a planned driving strategy for the upcoming road section, where the strategy takes into account the effects of predicted future braking torque to the powertrain;
- and
- control the powertrain of the vehicle in accordance with the planned driving strategy using the cruise control system, thereby controlling vehicle speed of the vehicle.
A cruise control system for a vehicle, the cruise control system comprising a control arrangement configured to control vehicle speed of the vehicle using the cruise control system, said vehicle comprising a power take-off configured to power an auxiliary power consumer, the power take-off being connected to a powertrain of the vehicle;
- wherein the control arrangement is configured to:
- in response to a determination that the power take-off is subjected to a load, predict future braking torque that will be applied to the powertrain by the power take-off during an upcoming road section as a result of the power take-off load;
- determine a planned driving strategy for the upcoming road section, where the strategy takes into account the effects of predicted future braking torque to the powertrain;
- and control the powertrain of the vehicle in accordance with the planned driving strategy using the cruise control system, thereby controlling vehicle speed of the vehicle.
