Method and device for preventing a surging of fluids in a tank of a tank truck
First Claim
1. A method for preventing a surging of fluids in a tank of a tank truck, during transportation, the tank truck having a drive train comprising an internal combustion engine, a clutch device and an automatic or automated manual transmission, the drive train being controlled by an electronic control unit which is configured to receive input data from detecting means for detecting a tank drive mode and sensing means for sensing a load status of the tank truck, the method comprising the steps of:
- detecting a tank drive mode, andpreventing surging of fluids in the tank bycalculating a launch gear as a function of detection tank drive mode and the load status of the tank truck, andlimiting a clutch device torque gradient as a function of detection of tank drive mode and the load status of the tank truck.

Abstract
A method and device for preventing a surging of fluids in a tank of a tank truck, during transportation, the tank truck having a drive train including an internal combustion engine, a clutch device and an automatic or automated transmission device, and the drive train is controlled by an electronic control unit (ECU), which is prepared to receive input data from an arrangement for detecting a tank drive mode and sensors for sensing a load status of the tank truck. The method includes detecting a tank drive mode, calculating a launch gear, and limiting the clutch device torque gradient.
