Abstract
A method for determining an axle load on a vehicle axle of a tractor includes providing a power lift and a payload coupled thereto, driving the power lift by a hydraulic pump, setting a pump pressure of the hydraulic pump as a function of the coupled payload, detecting the pump pressure by a sensor, and determining the axle load as a function of the detected pump pressure from characteristic data which represents a relationship between the pump pressure and the weight of the payload.
Claims13
A method for determining an axle load on a vehicle axle of a tractor, comprising:
- providing a power lift and a payload coupled thereto;
- driving the power lift by a hydraulic pump;
- setting a pump pressure of the hydraulic pump as a function of the coupled payload;
- detecting a current pump pressure by a sensor arranged at an outlet of the hydraulic pump, wherein the pump pressure is prevailing at the pump outlet and is detected at the pump outlet by the sensor which is arranged at the pump outlet between the hydraulic pump and a hydraulic controller;
- and
- determining the axle load from characteristic data which represents a relationship between the detected current pump pressure and the weight of the payload, wherein the characteristic data is generated during the course of a calibration outside operational use of the tractor when the tractor is at a standstill and other hydraulic loads or hydraulic consumers of the tractor connected to the hydraulic pump are switched off during the detection of the current pump pressure.
