Abstract
A vehicle electronic key includes: a receiver for receiving a request signal transmitted from an in-vehicle device; a transmitter for transmitting a response signal responding to the request signal; a key controller that determines whether the request signal has been received and controls the transmitter to transmit the response signal based on a determination that the request signal has been received; and an acceleration sensor that detects an acceleration applied to the vehicle electronic key and sets a vibration detection flag based on a determination that a vibration equal to or greater than a threshold value has been detected according to a detected acceleration.
