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

#CMT# #/CMT# 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). #CMT# : #/CMT# 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. #CMT#USE : #/CMT# Control apparatus i.e. gear box control apparatus, for controlling a partial mechanical synchronized gear box (all claimed) e.g. automated manual transmission and dual clutch transmission, in a powertrain of a vehicle such as electric car and hybrid car e.g. mild hybrid car and full hybrid car. #CMT#ADVANTAGE : #/CMT# The signal providing device comprises the instruction about the rotation speed difference between the transmission input shaft and the transmission output shaft if the state or the intentional state change meet the predetermined condition, thus preventing or overcoming blockage of mechanical synchronization of the gear box, and hence enabling switching of gears in the gear box in a comfortable, reliable and rapid manner while reducing energy requirement of the vehicle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a powertrain with a control device. 110 : Partial mechanically synchronized gear box 120 : Transmission input shaft 130 : Transmission output shaft 200 : Electromotor 220 : Control apparatus 230 : Receiving device 240 : Input signal 270 : Control signal 280 : Signal providing device.
