Abstract
Abstract In a remote control apparatus for a transmission, a gear change of a transmission is performed by auxiliary power, the auxiliary power is controlled upon change lever operation by a driver and, in case that the present selected position of the gear is different from the selecting position instructed by the change lever, the gear of the transmission is held in a neutral position for a predetermined period of time when the gear is moved from any shift position to the neutral position.

Claim 1
Independent Claim
327 words
A remote control apparatus for a transmission which has a selection path, a plurality of shift paths disposed parallel to each other and intersecting said selection path, neutral positions each of which is disposed at the intersections of said selection path and each of said plurality of shift paths, a shift position disposed at each end of each of said shift paths, and a striker which changes its position from one to another of said shift positions through at least one of said shift paths and at least one of said neutral positions, comprising: means for sending a signal representing an operation state of a change lever; auxillary power means, remote-controlled by said change lever, for changing a gear position of the transmission and sending a signal representing the gear position; and control means for controlling an operation of said auxillary power means in accordance with the change lever operation state signal and gear position signal, said control means being provided with neutral position holding means responsive to a signal indicating that the shift path on which the striker presently exists is different from the shift path instructed by said change lever, for holding for a predetermined period the striker in the neutral position on the current shift path of said striker; wherein said neutral position holding means comprises signal transmission delay means having: detecting means for detecting that the shift path on which said striker presently exists is different from the shift path instructed according to said change lever operating signal, then detecting that said striker has reached the first neutral position according to the neutral position signal and generating a neutral position detection signal; timer means, started in response to the neutral position detection signal, for generating an output signal when a predetermined period of time has elapsed; and gate means for opening a signal line between said control means and said auxiliary power means in response to an output signal from said timer means.

A remote control apparatus for a transmission which has a selection path, a plurality of shift paths disposed parallel to each other and intersecting said selection path, neutral positions each of which is disposed at the intersections of said selection path and each of said plurality of shift paths, a shift position disposed at each end of each of said shift paths, and a striker which changes its position from one to another of said shift positions through at least one of said shift paths and at least one of said neutral positions, comprising: means for sending a signal representing an operation state of a change lever; auxillary power means, remote-controlled by said change lever, for changing a gear position of the transmission and sending a signal representing the gear position; and control means for controlling an operation of said auxillary power means in accordance with the change lever operation state signal and gear position signal, said control means being provided with neutral position holding means responsive to a signal indicating that the shift path on which the striker presently exists is different from the shift path instructed by said change lever, for holding for a predetermined period the striker in the neutral position on the current shift path of said striker; wherein said neutral position holding means comprises signal transmission delay means having: detecting means for detecting that the shift path on which said striker presently exists is different from the shift path instructed according to said change lever operating signal, then detecting that said striker has reached the first neutral position according to the neutral position signal and generating a neutral position detection signal; timer means, started in response to the neutral position detection signal, for generating an output signal when a predetermined period of time has elapsed; and gate means for opening a signal line between said control means and said auxiliary power means in response to an output signal from said timer means.
Claim 3
Dependent Claim
14 words
An apparatus according to claim 1, wherein said timer means comprises a monostable multivibrator.
Claim 4
Dependent Claim
288 words
A remote control apparatus for a transmission which has a selection path, a plurality of shift paths disposed parallel to each other and intersecting said selection path, a plurality of neutral positions each of which is disposed at the intersections of said selection path and each of said plurality of shift paths, a shift position disposed at each end of each of said shift paths, and a striker which changes its position from one to another of said shift positions through at least one of said shift paths and at least one of said neutral positions, comprising: means for sending a signal representing an operation state of a change lever; auxiliary power means, remote-controlled by said change lever, for changing a gear position of the transmission and sending a signal representing the gear position; and control means for controlling an operation of said auxiliary power means in accordance with the change lever operation state signal and gear position signal, said control means being provided with; neutral position holding means, for holding the striker in said neutral position, said neutral position holding means comprising: signal transmission delay means having detecting means for detecting that the current shift path occupied by said striker is different from the shift path instructed according to said change lever operating signal, and detecting when said striker has reached a first neutral position and generating a neutral position detection signal; timer means for generating an output signal when a predetermined period of time has elapsed; said timer means being actuated in response to said neutral position detection signal; and gate means for opening a signal line between said control means and said auxiliary power means in response to an output signal from said timer means.
Claim 5
Dependent Claim
288 words
A remote control apparatus for a transmission which has a selection path, a plurality of shift paths disposed parallel to each other and intersecting said selection path, a plurality of neutral positions each of which is disposed at the intersections of said selection path and each of said plurality of shift paths, a shift position disposed at each end of each of said shift paths, and a striker which changes its position from one to another of said shift positions through at least one of said shift paths and at least one of said neutral positions, comprising: means for sending a signal representing an operation state of a change lever; auxiliary power means, remote-controlled by said change lever, for changing a gear position of the transmission and sending a signal representing the gear position; and control means for controlling an operation of said auxiliary power means in accordance with the change lever operation state signal and gear position signal, said control means being provided with; neutral position holding means, for holding the striker in said neutral position, said neutral position holding means comprising: signal transmission delay means having detecting means for detecting that the current shift path occupied by said striker is different from the shift path instructed according to said change lever operating signal, and detecting when said striker has reached a first neutral position and generating a neutral position detection signal; timer means for generating an output signal when a predetermined period of time has elapsed; said timer means being actuated in response to said neutral position detection signal; and gate means for opening a signal line between said control means and said auxiliary power means in response to an output signal from said timer means.
