Embodiment Construction

[0011] Below, according to Figure 1 ~ Figure 2 One embodiment of the electric steering lock device of the present invention will be described.

[0012] Such as figure 1 As shown, the electric steering lock device 1 includes a steering shaft 11 connected to a steering wheel, a lock lever 12 , a motor 13 as a driving device, and a steering lock ECU 14 as a control device. The steering lock ECU 14 is electrically connected to a motor 13 and a locked position detection switch 16 as a detection device. In this embodiment, the lock position detection switch 16 is a normally open (contact A) mechanical switch (limit switch in this example), one end of which is connected to the anode (+B) of the battery, and the other end is connected to the steering lock ECU 14 connected.

[0013] The outer surface of the steering shaft 11 is provided with a concave portion 11 a capable of receiving the front end of the lock lever 12 . In the state where the front end portion of the lock lever 1...

Abstract

The invention relates to an electric steering locking device. The locking device is characterized in that: the steering locking ECU(14) which is arranged at the electric steering locking device(1)can accept the detection signal from a locking position sense switch(16) corresponding to the position of a lock bar(12); a motor(13) can be driven according to the detection signal. When the motor is commanded to be driven, the detection signal is not input at the maximum power-on time(MT), the drive for the motor is stopped by the steering locking ECU. The steering locking ECU will store the detection state value which shows the implementation for the power-on control into a memory(14a). Thereby the maintenance worker can conveniently confirm whether the locking position sense switch is fault by checking the detection state value in the memory.

Description

technical field [0001] The invention relates to an electric steering locking device. Background technique [0002] In the past, mechanical steering locks were widely used to prevent vehicle theft. The mechanical steering locking device is to insert a mechanical key into the lock cylinder and turn the key so that the lock bar moves and engages with the steering shaft. Because the lock bar is engaged on the steering shaft, the steering shaft is fixed (locked), and the rotation of the steering wheel is restricted. Therefore, adopting the steering lock device improves the anti-theft property of the vehicle. [0003] However, in recent years, in order to improve the operability of vehicles, a push-button engine start / stop system that starts and stops an engine by pressing an operation button switch has been proposed. The steering lock device (electric steering lock device) of the above system moves the lock lever through a motor (driving device), and the driving of the motor i...
