Pedal map shift

A method for controlling a prime mover adapted to drive at least one ground engaging element of a working machine, comprising the steps of

• receiving an operator control input indicative of the control of the prime mover,
• determining at least one operation signal in response to the operator control input, which operation signal is sent for controlling the prime mover,
• receiving an operating state input indicative of an operating state of the working machine, and
• selecting a control mode in response to the operating state input, from at least one speed control mode, in which mode the determined operational signal comprises a desired speed of the prime mover, and at least one torque control mode, in which mode the determined operational signal comprises a desired torque of the prime mover,
• shifting the control mode from the torque control mode to the speed control mode when the machine switches to a reverse gear operating state.
