Embodiment Construction

[0025] Hereinafter, a steering lock device 1 according to an embodiment of the present invention will be described.

[0026] like figure 1 As shown, the steering lock device 1 is an electronic steering lock device, which uses the rotational driving force of the motor 10 to engage the lock lever 30 on the steering wheel center shaft 20 so that the steering operation cannot be performed. figure 1 The steering lock device 1 shown with figure 2 The main difference between the conventional steering lock device 100 shown in (a) to (c) is the operation at the time of reset. That is, the steering lock device 1 of the present embodiment includes a steering lock ECU (recognition device) 40 designed to immediately perform control on the premise that the unlocked state is in the unlocked state even when the steering lock ECU 40 is reset in the unlocked state. in addition, figure 1 Among the parts marked with the symbol, andfigure 2 The components (a) to (c) with the same symbols (fo...

Abstract

One of the requisite conditions for enabling a steering lock ECU 40 to acknowledge that the situation is in the unlocked condition will be met when all of the following three factors are met even in case resetting is generated in the unlocked condition. The three factors signify that a lock switch 41 is turned Off, an unlock switch 42 is turned On, and that the position data to show the unlocked condition is stored in a RAM 40a. Therefore, a control based upon the unlocked condition, for example the vehicle engine start control, can be conducted immediately when all factors are met even in case resetting is generated in the unlocked condition.

Description

technical field [0001] The present invention relates to a steering lock device which prevents the steering operation from rotating by using a lock lever to prevent the central axis of the steering wheel from rotating. Background technique [0002] In recent years, someone has proposed an electronic steering lock device (for example, refer to Japanese Patent Application Laid-Open No. 2003-063354), which uses the driving force of an operating mechanism such as a motor to move the lock lever to prevent the rotation of the steering wheel central axis, so that the car's Steering operation cannot be performed. [0003] Existing electronic steering lock device 100 such as figure 2 (a) ~ (c) shown. figure 2 (a) shows the state (locked state) in which the lock lever 30 is arrange|positioned at the lock position so that a steering operation cannot be performed. figure 2 (c) shows the state (unlocked state) in which the lock lever 30 is arranged in the unlocked position so that the ...
