Abstract: An automobile anti-theft device comprises a decoupling assembly having a first decoupling portion that couples to an accelerator system and a second decoupling portion that couples to a throttle system. The first decoupling portion and the second decoupling portion are removably rotatingly coupled together. The first decoupling portion comprises a first decoupling disc having a locking pin aperture. A locking pin assembly is configured to removably couple with the first decoupling portion. The locking pin assembly comprises a locking pin removably extendable into the locking pin aperture, such that when the locking pin is not extended into the locking pin aperture the accelerator system may operate the throttle system and the automobile's engine can rev above idle, and when the locking pin is extended into the locking pin aperture the accelerator system is prevented from operating the throttle system and the automobile's engine cannot rev above idle.

Abstract: A remote-controllable automobile anti-theft device replaces a common connection between the accelerator and the throttle of an automobile with a locking main shaft connector between an accelerator shaft and a throttle shaft. The locking main shaft rotates about a central axis in response to motion from the accelerator, and translates that motion to the throttle. The locking main shaft contains a hole. The remote control activates a push-pull solenoid which reversibly inserts a solenoid locking pin into the hole in the locking main shaft. When the solenoid locking pin is inserted into the hole in the locking main shaft, the locking main shaft is prevented from rotating around a pivot axis of the locking main shaft. Therefore, when the locking pin is inserted into the hole in the locking main shaft, motion of an accelerator shaft does not translate to the throttle shaft, and the automobile's engine cannot rev.
