摘要:
A wireless wake-up system and an operation method thereof are provided to optimize power consumption when wireless data is received. The wireless wake-up system activates a wake-up detection module and then compares a wireless input signal received through an antenna with a pre-stored reference value. If the wireless input signal is equal to the reference value, the wireless wake-up system determines that the input signal is a wake-up signal with a low bit rate, and then generates a wake-up command corresponding to the wake-up signal. Also, the wireless wake-up system activates a selected module kept in an inactive state by sending the wake-up command to the selected module. The activated module may be a microcontroller unit (MCU). When the MCU is activated, the wireless wake-up system may inactivate the wake-up detection module.

An antitheft method and system for motorcycles are provided. The antitheft method and system for motorcycles authenticate an electronic identifier when power-up of a motorcycle or engine start-up is sensed and cut off the power-up or engine start-up if the power-up or engine start-up is not authenticated. An electronic control unit can generate a theft alarm signal in case of unauthenticated power-up or engine start-up. The motorcycle engine is automatically stopped if the engine is started through an illegal method, and thus the motorcycle is prevented from being stolen. Further, a user can confirm the electronic identifier and start the motorcycle without inserting a key into a key cylinder, and thus the user can start the motorcycle easily and rapidly.

Provided are an apparatus and a method for starting an engine of an automobile using a start-button without a normal car key. In the apparatus and method, it is determined whether plural signals including the start-button are on. A key FOB is requested to transmit its ID, the ID is received from the key FOB, and authentication is performed on the key FOB using the received ID when the signals are on. Power is provided to a starting motor and a driving signal is applied to a motor driver to drive a motor when the key FOB passes authentication. A shaft is driven according to the operation of the motor to operate a steering column and the starting motor is driven to start the engine. A safety member is inserted into a first hole of the shaft to block the shaft from moving and rotating when the engine is started.
