Abstract

PURPOSE:To attain a shift lever device which can utilize a switch having a small electric capacity irrespective of presence of an ECT mechanism by mounting a driving circuit which drives an illumination lamp and an over drive mechanism driving solenoid in a shift lever device main body. CONSTITUTION:A drive circuit 100 is mounted on an ECU board 44 for directly driving an over drive driving solenoid. It is thus possible to utilize an over drive button 64 of a small electric capacity such as 20mA, even in the case that the ECT mechanism is not provided. When the over drive button is set ON, the drive circuit 100 supplies power to an illumination lamp 94 or an ECT computer. The illumination lamp 94 lights an indicator which indicates that the over drive mechanism is set ON. When a solenoid 98 is set ON, it enters into an over drive mode.

A pin (not shown) is separated from the cam on the shift lever 16, and L, R and P of the shift lever 16 are separated.
A button 60 for permitting movement to the position and an overdrive button 64 for instructing overdrive, that is, lockup of the torque converter are provided. Further, an electronic control unit (ECU) case 62 is provided on the rear side of the shift lever device body 12,
In the CU case 62, an ECU board 92 in which an ECU 90 (see FIG. 7) for controlling the shift lock release solenoid 48 for locking the shift of the driving position of the shift lever 16 and the key lock solenoid is mounted.
(See FIG. 7) is stored.

FIG. 7 shows a block diagram of an electrical system including the ECU board 92. The shift lock release solenoid 48 is connected to the ECU 90 in the ECU case 62 via the connector 82, and the parking position detection switch 58 for detecting whether the shift lever 16 is in the parking position is a connector. EC through 84
It is connected to the ECU 90 in the U case 62. Furthermore,
An I / O connector 86 is connected to the ECU 90 in the ECU case 62, and a connector 88 connected to the overdrive button 64 and the lighting device 80 is arranged adjacent to the I / O connector 86.

As a switch configuration of the overdrive button 64, an electronically controlled transmission (EC
T) and those that do not support T), and those that do not support ECT, as shown in FIG.
An illumination lamp 94 as an off display indicator and an overdrive mechanism driving solenoid 98 for driving the overdrive mechanism are connected in parallel. The switch configuration of the overdrive button 64 directly drives the overdrive mechanism driving solenoid 98, so that the switch has a medium current capacity (1.5
A) is used.

As shown in FIG. 8, the one with an ECT mechanism is provided with a lighting lamp 94 for displaying ON / OFF of the overdrive function on the instrument panel through a connector 88, and an ECT computer 96. Are connected in parallel, and an overdrive mechanism driving solenoid 98 is connected to the ECT computer 96. Therefore, E
A switch with a CT mechanism may have a small electric capacity (about 20 mA), but if the switches are divided according to the presence or absence of ECT, there is a disadvantage in terms of production cost such as increase in switch types and mold cost. , So in reality E
A switch with a medium current capacity is also used for the one with a CT mechanism.

Next, the operation will be described.

When the ECT mechanism is not provided, when the overdrive button 64 is turned on, power is supplied from the power source to the illumination lamp 94 and the overdrive mechanism driving solenoid 98, and the illumination lamp 94 has the overdrive function on. The overdrive mode is entered by illuminating an indicator that there is and solenoid 98 is turned on.

When the ECT mechanism is provided, when the overdrive button 64 is turned on, the illumination lamp 9
4 and the ECT computer 96 are supplied with power from a power source, the illumination lamp 94 illuminates an indicator indicating that the overdrive function is on, and the ECT computer 96 receives a predetermined signal based on the input signal from the overdrive button 64. An electric current is supplied to the overdrive mechanism driving solenoid 98. And the solenoid 98
Is turned on to lock up the ECT and enter the overdrive mode.

[0011]

As described above, the conventional shift lever device can be used with a small electric capacity (about 20 mA) when it is equipped with the ECT mechanism, but it does not work. Since the switch having the medium current capacity is used for the drive button 64, there is a problem that the switch becomes large and the cost is increased, and an occupied space becomes large.

The present invention has been made to solve the above problems, and a switch having a small electric capacity is provided by mounting a drive circuit for driving an ECT on an ECU board, regardless of the presence or absence of an ECT mechanism. It is an object of the present invention to provide a shift lever device that can be used.
