JPS6371456A - 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 confirmed by the light irradiation and sound, thus allowing the turning position of the rotor cam to be easily confirmed. 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. An illuminating device 13 having lamps for lighting the LOCK position, ACC position, ON position, and START position and a position confirmation control circuit 7 having a sound generating circuit 6 connected to the START position are connected with the motor operating device 5, and an ignition switch 8 is connected with the position confirmation control circuit 7. Therefore, the turning position of the rotor cam can be confirmed by the light irradiation and sound.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a motor-driven steering lock control device in which a steering lock is driven by a motor.

BACKGROUND OF THE INVENTION Conventionally, a so-called steering lock device installed in an automobile is used to start the engine by inserting a key into a cylinder lock provided in the steering lock device and sequentially rotating the cylinder lock from the lock position to the start position. It's starting.

Further, as the key rotates, a rotor cam provided at the rear of the cylinder lock works in conjunction with the locking bolt to move the locking bolt.

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 an accompanying item, for example, JP-A-59-19264
3 exists, but this invention incorporates a motor into the steering lock device, and by rotating the motor, the rotor cam is reciprocated from the lock position to the start position, and the ignition switch can be switched in the same way as a key operation. At the same time, the locking bolt is being moved.

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, is the position of the rotor cam rotated by the motor at the LOCK position? There is a drawback that it is difficult to know whether it is in the ON position or START position.

(1tLL) ＼ A steering lock device having a rotor cam driven by an L motor,
A microcomputer that controls the motor of this steering lock device, a rotor cam that rotates together with the motor under the control of this microcomputer, and the rotational position of this rotor cam are sequentially determined by light: 10 (position, ACC position, ON position, or START position). A light emitting circuit that connects a lamp that illuminates the position, and a sound generating circuit that notifies the START position by sound are installed so that each position can be visually and audibly heard at the same time.

Operation: When a plurality of push button switches are manually operated on the control station module according to a password, when the button of the present invention is rotated, the ignition switch is activated with the rotation of the rotor cam. are sequentially L[1(
: position, ΔCC position, ON position, or S T A
RT 4: Switch to i position and ST from this LOGK position
The light emitting circuit lights up the lamp up to the ART position, and at the same time, the lamp is illuminated at each position.At the same time, at the ON position or START position, a sound is also announced by the sound generation circuit, so if you press the push button (PI] Sl+) at this time, the The engine does not start. At this time, if you release your finger from the push button (PIISH), the engine will continue to start.

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

FIG. 2 is a block diagram of electrical control for driving the provided dryer (external shape not shown), and FIG. 2 is a perspective view of the main parts of the steering lock device.

In FIG. 1, a control stage module 2 with a plurality of push buttons 1 includes an A/D converter 3, a CPU having an arithmetic processing function, a read-only memory ROM for reading and writing. A microcomputer 4 equipped with a random access memory RAM and the like is connected. Connected to this microcomputer 4 is a motor actuating device 5 which is driven under the control of this microcomputer 4 and has one rotor cam (not shown).

In addition, a lamp that illuminates the 1.0 G, K, ACc, ON, and START (Q) positions was installed in the light emitting circuit 13, but a radio card or magnetic car 12 was connected, and a sound source was installed at the START position. A position confirmation control circuit 7 formed by connecting the generation circuit 6 is connected to the motor actuating device 5.

This position confirmation control circuit 7 connects an ignition switch 8 whose contacts are sequentially switched by the movement of the rotor cam of the motor actuating device and which has each contact point, and connects the ignition switch 8 to the start position (
START) 10 and push button (PUSH) 11 are connected to the ignition switch 8.

FIG. 2 shows a steering lock device A in which a push button (PUSH) 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 ISH) 11. In one embodiment of the present invention, a plurality of push buttons 1 are used to generate manual signals.

The control station module 2 may be modified to generate human input signals by means of cards, IC cards, etc.

Effects of the Invention As described above, the present invention provides a steering lock device driven by a motor with a position confirmation control circuit consisting of a light emitting circuit and a sound generation circuit, thereby sequentially emitting light from the LOCK position to the START position. This has a useful effect because it can be confirmed by audio.
