6 is connected to a contact point 166 for neutral provided in 6. The common contact side of the analog switch 156a is connected to a light emitting diode 146 as a neutral indicator.

The change switch 16 is configured to switch to the contacts 161 to 166 in conjunction with the number of stages of the transmission. The analog switches 151 to 155 are switched according to outputs out1 to out5 of the sign determination unit 17 by the processing described later. In addition, the analog switches 151a-
155a and 156a are switched according to the output out0 of the sign determination unit 17.

The sign determination unit 17 is constituted by a microcomputer including a CPU, a memory, and the like. The switches 181 to 185 of the indicators 141 to 145 formed by the ring 5 and the contact patterns P1 and P2 are connected to the input interfaces A1 to A5 of the sign determination unit 17 via the resistors R1 to R5. Note that pull-down resistors R11 to R15 are connected to the input interfaces A1 to A5.

Outputs out1 to o of the code determination unit 17

To 155a and 156a are controlled collectively. Output out
When all 0 to out5 are high (H), all the analog switches 151 to 155 are switched to the resistors r1 to r5, and all the analog switches 151a to 156a are turned off. Then, the light emitting diodes 61 to 65 of the indicators 141 to 145 are all turned on.

If all the outputs out1 to out5 are low (L), all the analog switches 151 to 155 are switched to the analog switches 151a to 155a, and all the analog switches 151a to 156a are turned on. Contact 161 of
To 166. In this state, indicator 1
Reference numerals 41 to 145 and 146 turn off the light except for those corresponding to the switching positions of the change switch 16.

Further, one of the outputs out1 to out5
If only one is low, analog switches 151-155

9 and a memory 20 in which a password can be registered in advance. The determination unit 26 compares the personal identification number read into the buffer 19 with the personal identification number set in the memory 20. Then, based on the result of the comparison, an instruction to permit / disallow the start of the engine is output. Specifically, an ignition permission command, a fuel supply command, a starter motor rotation permission command, and the like are output as an engine start permission command. When the password is confirmed, the analog switches 151 to 15
5 is switched to the side of the second electronic switch unit 10a, and the analog switches 151a to 155a are switched to the side of the change switch 16, respectively.
Reference numeral 146 indicates the gear position.

FIG. 5 is a flowchart showing the main processing of the power-on device. This process is executed after the main switch 3 is turned on. In step S1, the data in the buffer 19, that is, the indicators 141 to
Clear the password entered from step 5. Step S2
Then, the outputs out1 to out5 are all set to high (H) so that the indicators 141 to 145 are all turned on. The output out0 is also set to high (H). Output ou
By setting all of t1 to out5 to high (H), the analog switches 151 to 155 are all connected to the resistor r1.
To r5, all the light emitting diodes 61 to 65 are energized. By turning on all the indicators 141 to 145, a "standby state" in which a password can be input can be displayed, thereby facilitating the night operation.

In step S3, the indicators 141 to 141
The presence or absence of the operation of 145 is determined. If an operation has been performed, the process proceeds to step S4, where the operated indicator is blinked. That is, among the outputs out1 to out5, the one corresponding to the operated indicator is alternately switched to “high / low”. The indicator flashes for a few seconds.

In step S5, the number corresponding to the operated indicator is stored in the buffer 19. In step S6, it is determined whether the input is completed. For example, 5
If the password is a digit password, when five numbers are stored in the buffer 19, step S6 becomes affirmative. When the input is completed, the process proceeds to step S7, where the password registered in the memory 20 is compared with the input password stored in the buffer 19.

If the passwords match, step S8
Then, the outputs out1 to out5 are set so that the gear positions can be displayed by the indicators 141 to 145.
That is, the outputs out1 to out5 and out0 are all set to low (L). In steps S9 and S10, ignition permission and start permission are output, respectively. Note that all of the indicators 141 to 145 may blink several times so that the user can recognize that the passwords match.

If the input password is not correct, the process proceeds to step S11, in which all the outputs out1 to out5 are set to low (L) so as to turn off all the indicators 141 to 145, and the output out0 is set to high (H). .
As a result, the password input function by the indicators 141 to 145 is stopped.

If the indicators 141 to 145 are not operated after all the lights are turned on in step S2, step S3
Then, the process proceeds to step S12, where it is determined whether or not the scheduled standby time T has elapsed. If the time T has elapsed, an input error occurs and the process ends. If an input error occurs or the passwords do not match, it is preferable that the main switch 3 be turned off once before the password is accepted. However, the number of allowable errors is set in advance. Alternatively, the process may return to step S1 and wait for the input of the personal identification number until the allowable number of errors is reached.

As described above, in this embodiment, the interlock mechanism for preventing theft can be added without adding a space by using the indicator for displaying the switching position of the transmission also as the password input means. .

In the above-described embodiment, the light emitting diode is used as a means for irradiating the lens 8 of the indicator. However, the present invention is not limited to this, and a light bulb may be used. The switches 181 to 185 are of a type in which the conductive rubber ring 5 is pressed, but may be those that open and close mechanical contacts.

In particular, according to the invention of claim 2, the space provided for displaying the gear position can be effectively used as it is for inputting the password information.

According to the third aspect of the present invention, the switching between the password information input function and the gear position display function is automatically performed, and according to the fourth aspect of the invention, the acceptance of the password information is permitted. Are clearly shown to the user, so that the operability is good in each case.

According to the fourth aspect of the invention, the reception of the password information is not permitted in a state where the main switch is not turned on, that is, in a state where there is no reliable operation by the user. If there is an error in the input, the reception of the password information is not permitted thereafter. Further, according to the invention of claim 7, when an error occurs, the input of the password information is permitted through a certain procedure.
