1. Electric locking device for locking brake, clutch, or accelerator pedal of an automobile comprising:

  • an encoder 5, a decoder 6, a control circuit 7 for controlling the operation of the motor and controlling the operation of the theft prevention systems working together with the locking device, driver circuit 8 for amplifying and formatting signals into a suitable form to control motor operations, motor 9 which functions as a power source in moving the mechanism for locking brake, clutch, and/or accelerator pedal 10 to carry a locking member 29 into locking or unlocking condition with the brake, clutch, and/or accelerator pedal to prevent these parts from functioning normally;

    the said mechanism being assembled to a rotation axle of the motor and then encased in a metal cylinder 28 to protect the mechanism and internal device from damage, a master lock for unlocking in case the electrical circuit or motor fails to operate. Characterized in that the decoder 6, control circuit 7, driver circuit 8 including connections between these circuits to the motor are encased to protect from damages or changes of connections of the circuits, these parts operating together in such a manner that when the decoder 6 receives an instruction signal to lock or unlock from the device or encoder 5, it will compare the code signal with a predetermined code for a matching and if the code signal matches the predetermined code, then a signal will be sent to the control circuit 7 to make the control circuit send an output 11 to control the operations of the theft prevention systems working together with the locking device and send a control signal 40 to a driver circuit to amplify and format signals into a suitable form to drive the motor 9 in order to rotate the locking mechanism 10 to carry a locking member 29 to move to lock the brake, clutch, and/or accelerator pedal of a vehicle so they cannot be used or moved to unlock the brake, clutch, and/or accelerator pedal of a car so they cannot be used;

    the control circuit also monitors the distance and position of the travel of the locking mechanism or the rotation position of the motor to determine whether it is in locking or unlocking conditions by comparing the electrical current used in driving the motor and/or counting the revolutions of the motor and/or receiving a signal from a sensor when the sensor detect the locking or unlocking position of the mechanism;

    when any part of the electrical circuit or motor fails to function, a key can be used to unlock the master lock to disengage the locking mechanism and the encoder 1 can be used to send a signal to reset to the decoder 2 provided separately in order to make the decoder compare the code signal received with a predetermined code and send a signal to disable the theft prevention systems 3 for matching in order to send an output 4 to reset the theft prevention systems working together with the locking device.
