JPS6371455A - Steering lock controller driven by motor - Google Patents

Abstract

PURPOSE:To improve the using performance by allowing the turning position of a rotor cam installed onto a motor for driving a steering lock to be successively informed by sound, thus allowing the turning position of the rotor cam to be confirmed by ears. CONSTITUTION:In an electronic controller which drives a motor installed into a steering lock device, a control station module 2 having a plurality of push bottons 1 is connected with a microcomputer 4 having a CPU, through an A/D converter 3, and controls a motor operating device 5 having a rotor cam by the output of the CPU. A sound control circuit 7 which connects each contact point for LOCK position, ACC position, ON position, and START position with a sound generating circuit 6 is connected with the motor operating device 5, and an ignition switch 8 is connected with the sound control circuit 7. Therefore, the turning position of the rotor cam installed onto the motor can be successively informed by sound, and using performance can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a steering lock control device driven by a motor, which is operated by a dryer that drives the steering lock.

2. Description of the Related Art Conventionally, a so-called steering lock device installed in an automobile is operated by inserting a key into a cylinder lock provided in the steering lock device and locking the cylinder lock into a lock 4.
The engine is started 17 by sequentially rotating it from the I7 position to the start position.

Also, as the key rotates, the rotor cam installed at the rear of the cylinder lock locks the lock! This locking bolt is moved in conjunction with ・.

In addition, a steering wheel is provided on the head of the case body of this cylinder lock so that it can be rotated with a finger, without using a key, and the locking bolt can be moved by rotating this heir. There is also a locking device.

Furthermore, as a steering lock device that has already been published as a publication, for example, JP-A-59-1921i
43, but this invention incorporates a motor into the steering lock device, energizes this motor with an electronic button or radio waves, and rotates the motor to reciprocate the rotor cam from the lock position to the start position. The locking pole is moved at the same time as the ignition switch is turned on, similar to key operation.

Problems to be Solved by the Invention In a steering lock device in which a rotor cam built into the steering lock device is driven by a motor, it is difficult to determine whether the rotor cam rotated by the motor is at the LOCK position or AC (: Q There is a drawback that it is difficult to know which position, the ON position, or the 5TART position.

Means for Solving the Problems The purpose of the present invention is to eliminate such drawbacks by providing a steering lock device having a rotor cam driven by a motor, a microcomputer for controlling the motor of the steering lock device, and a microcomputer for controlling the motor of the steering lock device. A rotor cam that rotates together with the motor under the control of the rotor cam, and a sound generation circuit that sequentially announces the rotational position of the rotor cam by voice are provided, and the rotational position of the rotor cam can be confirmed with the ear by the sound generation circuit. It is in.

Operation: When you manually press the multiple push button switches on the control station module according to the password, the computer drives the motor, and when the rotor cam rotates with the motor, the ignition switch sequentially moves to the 10GK position as the rotor cam rotates. Switch to the CC position, ON position, or 5TART position, and each time you switch between these positions, you will be notified with a voice that the station is closed, and the O
When the rotor cam is located at the N position or the 5TART position, a voice command is given to press a push button switch provided on the steering lock device. When the engine starts, this push-button switch is automatically reset by releasing the finger and being biased by the spring. At this time, the position of the contact point of the rotor cam is reversed together with the motor to the ON position of the ignition switch.

Example An embodiment of the present invention will be described below with reference to the drawings.

In the drawings, FIG. 1 is a block diagram of electrical control for driving a motor (external appearance not shown) provided in the steering lock device A, and FIG. 2 is a perspective view of the main parts of the steering lock device A.

In FIG. 1, a CPU having an arithmetic processing function and a read-only memory ROM for reading are written to a control station module 2 equipped with a plurality of push buttons 1 to a D/D converter 3. A microcomputer 4 provided with M and the like is connected to a random access memory l'l. This microcomputer 4 is driven by the control of this microcomputer 4, 1. A motor actuating device 5 with a rotor cam (not shown)
Connect.

In addition, each LOCK position, Ace position,
The voice control circuit 7, which connects the contacts at the ON position and the 5TART position, is connected to the motor actuator 5, and the contacts are sequentially switched by the movement of the rotor cam of the motor actuator 5. Connect the ignition switch 8 with the start position (5TART)
Connect 10 and push button (PIISll) 11, and connect to ignition switch 8.

FIG. 2 shows a steering lock device A in which a push button (Pl]SN) 11 is provided at the center of the front surface of the housing 9.
A motor actuating device 5 is provided at the rear position of HsH) 11. In one embodiment of the present invention, a plurality of push buttons 1 are used to input human power signals, but the control station module 2 may be modified to generate human power signals using a radio wave card, a magnetic card, an IC card, etc. .

Effects of the Invention As described above, the present invention provides a steering lock device driven by a motor, by providing a voice control circuit consisting of a voice generating circuit that sequentially announces the rotational position of a rotor cam provided in the motor by voice. , CC position, ON position, or 5TART position can be confirmed by voice, which has a useful effect.
