Abstract

The invention relates to a method for changing gear ratio in a gearbox (2) of a vehicle (1), said gearbox (2) being arranged to transfer torque in a powertrain (3) between a power source (4) and at least one drive wheel (8) of said vehicle (1), said gearbox (2) being controllable to engage at least two gears having different gear ratios, the method comprising steps of: - applying a first force (Fa-i) acting on an engaging element (43) arranged between said gearbox (2) and said at least one drive wheel (8); - decreasing torque (Ts) generated by the power source (4); - disconnecting said gearbox (2) from said at least one drive wheel (8) by means of the first force (Fa-i) acting on the engaging element (43) when the first force (Fa-i) overcomes a reaction force (Fr) acting on the engaging element (43), which reaction force (Fr) is a result of a torque (Ts) transferred by the engaging element (43); - changing gear ratio of said gearbox (2) when the gearbox (2) is disconnected from said at least one drive wheel (8); and - connecting said gearbox (2) to said at least one drive wheel (8) when said gear ratio of said gearbox (2) has been changed. The invention also relates to a computer program comprising program code, a system for changing gear ratio in a gearbox (2) of a vehicle (1), and a vehicle (1).(Fig. 2)
