Abstract
A method for controlling a vehicle device (10) configured to cool of a vehicle unit (20) includes reading in temperature information which is functionally related to an operation of the vehicle unit (20) and determining a temperature gradient. The method also includes checking whether the information read in exceeds a threshold value for the information read in, checking whether the temperature gradient determined exceeds a threshold value, and emitting a signal for the control of the vehicle device (10) as a function of check results of the checking steps, in order to bring about the cooling of the vehicle unit (20) by the vehicle device (10). In addition, a control unit (100) for carrying out the method and a vehicle (200) with a control unit (100) of that type.
Claims11
A method for controlling a vehicle device configured to bring about the cooling of a vehicle unit, the method comprising:
- reading-in a temperature which is in functional relationship with an operation of the vehicle unit;
- determining a gradient of the temperature;
- checking whether the gradient exceeds a threshold value;
- and
- emitting a signal for controlling the vehicle drivetrain as a function of a check result of checking whether the gradient exceeds the threshold value, in order to bring about the cooling of the vehicle unit by limiting drivetrain torque and/or limiting a drivetrain rotation speed.
A control unit for controlling a vehicle device configured to bring about the cooling of a vehicle drivetrain, the control unit comprising:
- an interface for reading in a temperature which is in functional relationship with an operation of the vehicle drivetrain;
- a computing system configured to determine a temperature gradient on the basis of the temperature read in, wherein the computing system is configured to check whether the temperature gradient exceeds a threshold value for the temperature gradient;
- and
- an interface for emitting a signal for the control of the vehicle device as a function of a check result of checking whether the temperature gradient exceeds the threshold value, in order to bring about the cooling of the vehicle drivetrain by one or more of limiting drivetrain torque and limiting a drivetrain rotation speed.
