Abstract
The invention relates to a method and an arrangement for controlling a gearshift in a vehicle with a transmission (120) comprising a stepped gearing, the transmission (120) being arranged between an engine (110) and at least one driven axle (123), wherein the engine and the transmission are controlled by an electronic control unit (140), The method involves monitoring at least one parameter related to a vehicle operating condition; registering that a manual upshift command is requested; determining a desired shift point and a target engine speed based on a parameter comprising at least current engine speed; and performing an upshift when the target engine speed is reached.

A method to control a gearshift in a vehicle with a transmission comprising a stepped gearing, the transmission being arranged between an engine and at least one driven axle, wherein the engine and the transmission are controlled by an electronic control unit, the method comprising:
- monitoring at least one parameter related to a vehicle operating condition;
- registering that a manual upshift command is requested;
- determining a desired shift point and a target engine speed based on a parameter comprising at least current engine speed;
- and
- performing an upshift at a delayed point in time after the manual upshift command is requested and when the target engine speed is reached.
An arrangement to control a gearshift in a vehicle with a transmission comprising a stepped gearing, the transmission being arranged between an engine and at least one driven axle, wherein the engine and the transmission are controlled by an electronic control unit, wherein
- the electronic control unit is arranged to monitor at least one parameter related to a vehicle operating condition;
- the electronic control unit is arranged to register that a manual upshift command is requested by the driver;
- the electronic control unit is arranged to determine a desired shift point and a target engine speed based on a parameter comprising at least current engine speed;
- and
- the electronic control unit is arranged to generate instructions to the transmission to perform an upshift at a delayed point in time after the manual upshift command is requested and when the target engine speed is reached.
