A method, a device and a system for communicating in a vehicle at least one deviation of a measured actual vehicle parameter value from its predetermined value to a driver involve determining an amount of the deviation, color-coding the amount of deviation, and communicating the amount of deviation to the driver by using the color-code. The counting information represents the number of rotations counted from a predetermined time. The amplitude of the opening width oscillation is set to ta quantity, which des not provoke any plastic deformation of the strand shell.
