JPS6371458A - Steering lock controller driven by motor - Google Patents

Abstract

PURPOSE:To permit the certain start operation by allowing the turning position of a rotor cam installed onto a motor for driving a steering lock to be informed by sound and allowing an engine to be started by the push botton operation at the START position. 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 l 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 a sound generating circuit 6 with each position of LOCK position, ACC position, ON position, and START position is connected with the motor operating device 5, and an ignition switch 8 is connected with the sound control circuit 7. Further, an engine can be started by pressing-operating a push button 11 built in the steering lock device when the rotor cam turns to the START position.

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.

2. Description of the Related Art 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 a publication, for example, Japanese Patent Application Laid-Open No. 59-19264
3, but this invention incorporates a motor into the steering lock device, energizes the motor using an electronic button or radio waves, and rotates the motor to move the rotor cam from the lock position to the start position. The reciprocating motion allows the locking bolt to be moved at the same time as the ignition switch is switched, similar to key operation.

When the key is inserted into the cylinder lock provided on the steering lock and the key is turned to the START position,
The engine can be started. Furthermore, when the engine is started, the key is immediately returned to the ON position to prevent the ignition system from malfunctioning, but this key is biased by a spring and automatically returns to the ON position.

Furthermore, it is necessary to provide a control device for reversing the rotor cam from the START position to the ON position.

Problems that the invention aims to solve: After starting the engine, immediately turn it on from the START position.
The rotor cam must be returned to the position, but when driving with a motor, unlike the key, it is
Since the timing for returning to the N position is important, manufacturing a specific control device that functions with such timing has the drawback of being expensive.

Means for Solving the Problems The purpose of the present invention, in order to eliminate such drawbacks, is to manually control the timing of returning from the START position to the ON position in the same way as with conventional key operations. I
When the rotor cam is at the start position, the start position is announced by voice by the voice control circuit, and in accordance with this voice announcement, for example, the center of the front part of the steering lock device is When the provided push button is pressed, an engine (not shown) is started, and when the engine is started by the operation of this push button, the push button is automatically returned by a spring by immediately releasing the hand from the push button.

Operation: When you manually press the multiple pushbutton switches on the control station module according to your password, the computer drives the motor, and when the rotor cam rotates with this motor, the rotor cam 1 is at the OC position, the ^CC position, and the ON position. , or to the START position, and each rotation position is announced by voice from the audio control circuit each time the position is switched. Also, when the rotor cam is positioned at the ON position or START position, the steering lock is activated at E+7. A command is given to press a push button switch provided on the 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 above with reference to the drawings.
