Control apparatus i.e. gear box control apparatus, for use in e.g. electric car, has signal providing device comprising instruction about rotation speed difference if state or intentional state change meet predetermined condition

摘要

The apparatus (220) has a receiving device (230) for receiving an input signal (240) and information about a state or an intended state change of a partial mechanically synchronized gear box (110). A signal providing device (280) provides a control signal (270) and comprises an instruction about rotation speed difference between a transmission input shaft (120) and a transmission output shaft (130) if the state or the intentional state change meet a predetermined condition. The transmission input shaft is coupled with an electromotor (200). The input signal and the control signal are formed as an electrical signal or an optical signal. Independent claims are also included for the following: (1) a method for overcoming or preventing blockage of mechanical synchronization (2) a program comprising a set of instructions for executing a method for overcoming or preventing blockage of mechanical synchronization.
