Embodiment approach 1

[0038] Hereinafter, the present invention will be specifically described based on the drawings showing the embodiments thereof. figure 1 and figure 2 It is a block diagram showing the structure of the door lock system of this embodiment. The door lock system of the present embodiment includes a vehicle door lock control device (vehicle lock control device) 10 mounted on a vehicle 1 and a portable wireless key 5 held by a user. The vehicle door lock control device 10 and the wireless key 5 can transmit and receive information by wireless communication. The vehicle door lock control device 10 is a device that controls locking / unlocking of one or a plurality of doors (not shown) of the vehicle 1 , and is, for example, a vehicle body ECU or the like. The vehicle door lock control device 10 controls the operation of the door lock mechanism 3 to lock / unlock the doors according to the user's operation on the lock operation unit (not shown) provided on each door of the vehicle 1 or...

Embodiment approach 2

[0070] Figure 7 It is a schematic diagram for explaining the door lock control performed by the vehicle door lock control device 10 according to the second embodiment. In the door locking system according to the second embodiment, the antenna 14a for short-range wireless communication is provided in four places of the vehicle 1, namely, the driver's door, the front passenger's door, and the left and right rear seats' doors (however, in the Figure 7 The illustration of the reference numeral 14a of each antenna is omitted in the figure). The communication range of each antenna 14a is within the range of tens of centimeters to several meters centered on the door where the antenna 14a is provided (refer to Figure 7 4 dotted circles in ). In addition, the communication ranges of the four antennas 14a overlap with each other but are different from each other.

[0071] After the control unit 11 of the vehicle door lock control device 10 according to Embodiment 2 receives an unl...

Abstract

The present invention provides a vehicle lock control device capable of improving the safety performance of a vehicle by automatically locking the doors of the vehicle at an appropriate time. A human detection sensor (2) is provided in a vehicle (1), and a vehicle door lock control device (10) detects a human present around the vehicle (1) based on an output signal of the human detection sensor (2). A vehicle door lock control device (10) includes a short-range wireless communication unit (14) for performing wireless communication with a wireless key (5) within a short distance from a vehicle (1), and a short-range wireless communication unit (14) for performing wireless communication with a wireless key (5) within a long-distance range. ) a long-distance wireless communication unit (15) for wireless communication. A vehicle door lock control device (10) determines a timeout period from unlocking the doors of the vehicle (1) to automatic locking based on the presence or absence of communication between the wireless communication unit and the wireless key (5).

Description

technical field [0001] The present invention relates to a vehicle lock control device that controls locking / unlocking of doors of a vehicle. Background technique [0002] Conventionally, a system for locking / unlocking (locking / unlocking) a door of a vehicle based on an operation of an operation unit provided on a wireless communicator held by a user is widely used. The wireless communicator is provided, for example, as an integral type with a vehicle key or a separate key holder type. For example, a vehicle lock control device is mounted on a vehicle as a vehicle body ECU (Electronic Control Unit, Electronic Control Unit), and the vehicle lock control device performs wireless communication with a wireless communicator to lock / unlock the doors. Furthermore, the vehicle lock control device has a function of automatically locking the vehicle door after a predetermined time elapses when the vehicle door is unlocked by operating the wireless communicator.
