    • PROBLEM TO BE SOLVED: To provide an electronic key system capable of shortening time required for ID verification of an electronic key.SOLUTION: When an electronic key 2 is activated by an wake signal 16 from verification ECU9, the electronic key 2 returns an ACK signal 17 as response. The ACK signal 17 is a key-specific signal in which a bit position of "1" is changed for every electronic key 2. When the verification ECU9 receives the ACK signal 17, it grasps which registration key is the electronic key 2 which is a current communication partner based on the bit position of the ACK signal 17. While transmitting a challenge 18 for challenge response authentication after receiving the ACK, the verification ECU9 then transmits only a key number 19 of the electronic key 2 which is the current communication partner.

    • PROBLEM TO BE SOLVED: To provide a communication area formation device capable of forming a desired communication area regardless of an antenna mounting direction.SOLUTION: A first transmission antenna 24 has two bar antennas 41 and 42 which are orthogonal to each other and are driven simultaneously. Individually setting values of drive currents Ix and Iy supplied to both bar antennas 41 and 42 makes it possible to arbitrarily control magnetic distribution, which is a direction and magnitude of directivity of a synthetic magnetic field Hxy synthesized from a magnetic field Hx by one bar antenna 41 and a magnetic field Hy by the other bar antenna 42, in a communication area 51. Thereby, a desired communication area 51 can be formed regardless of a mounting direction of the first transmission antenna 24. Second and third transmission antennas 25 and 26 are similar to the first transmission antenna 24.

    • PROBLEM TO BE SOLVED: To provide an on-vehicle system capable of acquiring a result of ID collation without adding any change to an existing electronic key system.SOLUTION: A period information detecting section 31 detects a change of an electric signal supplied from a collation ECU 5 to an out-vehicle transmitter 9 by a coil 31a, and generates period information of the electric signal based on the detection result. A determination section 32b determines success or failure in out-vehicle ID collation by analogical inference of a state of the out-vehicle ID collation by the collation ECU 5 from the period information. When it is determined that the out-vehicle ID collation is established by the determination section 32b, a lid lock control ECU 32 switches a state of a lid lock system 30 from a locked state to an unlocked state by driving a lid lock actuator 33 when it is recognized that a lid switch 34 is pressed for the predetermined period (for example, five seconds) or longer.
