The presently disclosed subject matter is directed to an anti-theft device for use with a motorized vehicle, such as a riding lawn mower. The device comprises a main body defined by first and second ends. Each end of the device comprises a pair of arms, each with a distal end and a proximal end. The distal end of each arm includes an aperture sized and shaped to allow a lock or other securing element to pass therethrough. For example, with riding lawn mowers, the disclosed device can be used to lock the mower handles in an off position, so that the mower cannot be started until the device is removed.

A steer-by-wire steering system for motor vehicles may include a primary steering level with a steering transmission device, which is arranged to subject wheels of the motor vehicle to a desired setpoint steering effect, and a secondary steering level with a safety device that provides predefined functions, so that in the case of a malfunction of the primary steering level, steering the wheels remains possible during an emergency mode. The steer-by-wire steering system may also include an authentication system with a communications interface for communications with the safety device. The authentication system may be arranged so that in the case of a successful authorization, the secondary steering level of the steer-by-wire steering system is also available after the emergency mode.

A vehicular authentication device that includes: a first processor; and a second processor. The first processor is configured to: perform a first permission to permit release of a steering lock of a vehicle in a case in which a verification of key information of the vehicle has been performed successfully, and in a case in which the steering lock has been released by the first permission, perform a second permission to permit deactivation of an immobilizer of the vehicle based on a successful verification of biometric information by the second processor.

A locking mechanism for a motor is provided. The locking mechanism includes a detent mounted on a shaft coupled to the motor, and a solenoid including an electromagnetic coil, a plunger, and a spring that holds the plunger at an extended state. The plunger engages the detent at the extended state when no voltage is applied, and the spring is configured to exert a predetermined force for the plunger to engage the detent to lock the shaft. The plunger retracts away from the detent to allow rotation of the motor shaft when a voltage is applied to the solenoid.

A steering lock device includes a trigger that is displaced as a frame cover drops from a frame, an auxiliary lock device that holds a lock member in a locked position as the trigger is displaced under condition that the lock member is positioned in the locked position, a housed component that is arranged in a housing chamber defined by the frame cover and the frame or in a guide hole, and a trigger coupling member that couples the housed component and the trigger. When the housed component is displaced, the trigger is displaced via the trigger coupling member.

An ignition device for a motor of an automotive vehicle is provided that the device includes a rotor configured to receive a key and mounted in rotation on a bracket, the rotor including a retainer configured to retain the rotor in translation relative to the bracket, and a first push back device configured to apply a linear force between the bracket and the rotor along an axis parallel to the axis of the rotation of the rotor. The bracket and the retainer are configured to cooperate so as to inhibit the rotation of the rotor in a predetermined direction from a predetermined angular position and to allow the rotation of the rotor beyond the predetermined angular position in the predetermined direction upon preliminarily applying a force on the rotor in an opposite direction to the direction of the linear force applied by the first push back device.
