  • Controlling the automatic starting of a motor vehicle uphill in a ? split situation
    Patent number: 10703376
    Abstract: A method is described for controlling the automatic starting of a motor vehicle comprising an electronically controllable locking differential, uphill in a split mu situation. The method comprises the following steps: determining the positive gradient of the underlying surface; defining an initial locking torque on the basis of the determined positive gradient and on the basis of a component of the torque which the vehicle requires to travel uphill with only the first driven wheel powered; calculating the slip ratio SRxx for the first driven wheel xx according to SRxx=(Vxx?VRef)/VCrit if the reference velocity VRef is between 0 and a critical velocity VCrit, and according to SRxx=(Vxx?VRef)/VRef if the reference velocity VRef is higher than the critical velocity VCrit; and defining the locking torque of the electronically controllable locking differential on the basis of the slip ratio of the first driven wheel.
