US 4,646,582 A · Operating device for transmission

Abstract

An operating device in which a speed change operation performed by a manual operating member is boosted by electric energy or hydraulic pressure or the like and transmitted to the transmission, wherein if an operator moves the manual operating member to perform the speed-change operation, a high reaction force is applied against the movement of the manual operating member by an interference device until the speed change condition of the transmission has reached the one desired and in turn when the speed-change condition of the transmission reaches the one desired, operation of the interference means is controlled by a control means, resulting in applying a low or no reaction force in respect to the movement of said manual operating member, thereby the operator can be apprised of the completion of the speed-change operation of the transmission through a rapid decrease in resistance to operation of the manual operating member, and upon completion of the speed-change operation, the operator may direct his efforts to other operating functions without being concerned with the speed change operation. Since a tactual sense of the operator is applied to detect a completion of the speed-change operation of the transmission, his sense of sight and hearing can be applied to assuring safety in running operation of the vehicle or the like and thereby a quite safe operation of the vehicle can be assured.

Dependent claims

An operating device for a transmission comprising:

a manual operating member movable selectively along an operating pattern consisting of a passage of a selecting direction and a plurality of shift directions;
signal generating means for generating an instruction signal corresponding to an operation of said manual operating member by detecting movement of said manual operating member to effect a speed change,
signal processing means for generating a speed change signal in response to said instruction signal,
gear shift means for changing the condition of the transmission in response to said speed change signal from said signal processing means,
interference means engageable with said manual operating member and applying to said manual operating member a reaction force to interfer with but not prevent speed change movement of said manual operating member,
sensing means for detecting the condition of said transmission and outputting a signal when the transmission has been shifted to the condition corresponding to said speed change signal, and
control means for controlling the reaction force of said interference means according to the output signal of said sensing means,
said control means being constructed to release the reaction force of said interference means when said sensing means detects that said transmission has been shifted to the condition corresponding to said speed change signal in order to complete a shift as a result that said manual operating member moves along a selected shift direction.
