Embodiment approach 1
[0076] refer to Figure 1 to Figure 10 , the door lock locking and unlocking system according to Embodiment 1 of the present invention will be described. In Embodiment 1, a system in which a lock command or an unlock command is sent from a user terminal 37 to an on-vehicle device 1 of a vehicle 2 via a server 3 to lock or unlock a door lock by the on-vehicle device 1 will be described. For locking and unlocking of the door locks, the terms so-called internal relays and external relays are used. In addition, in this embodiment, regarding the operation of switching the vehicle to a non-startable state, an internal combustion engine vehicle running using an internal combustion engine such as a gasoline engine is exemplified, and an engine start control line (ST line) that cuts off the internal combustion engine by using the engine start external relay 20 will be described. 23 and switched to the form of the system that cannot be started. Here, the operation of switching the veh...
Embodiment approach 2
[0169] refer to Figure 11 , an example of car sharing will be described with respect to the door lock locking and unlocking system according to Embodiment 2 of the present invention. Figure 11 It is an overall view of a system for locking and unlocking a door lock according to Embodiment 2. right with Figure 1-10 The same symbols are assigned to common configurations, and explanations thereof are omitted. In the first embodiment, the lock command and the unlock command are sent to the vehicle-mounted device 1 from the user terminal 37 via the server 3, but in the second embodiment, the difference from the embodiment is that the user terminal 37 directly sends the command to the vehicle-mounted device 1. Lock command and unlock command.
[0170] First, the flow from the reservation of the specific vehicle 2 by the user terminal 37 to the unlocking of the specific vehicle 2 will be described. A plurality of business offices (manned or unmanned parking lots, etc.) are regi...
Embodiment approach 3
[0186] refer to Figure 12 , the operations of the internal relay and the external relay according to Embodiment 3 of the present invention will be described. in addition, Figure 12 It is a wiring diagram of the door lock actuator control circuit 26A in the third embodiment. According to the wiring conditions of the 12V power supply and ground, the door lock actuator control circuit 26 has the following five forms.
[0187] (1) Negative control (usually, the lock line and unlock line are 12V power supply)
[0188] (2) Positive control 1 (normally, the lock wire and unlock wire are grounded)
[0189] (3) Positive control 2 (normally, the lock line and unlock line are open)
[0190] (4) Negative and positive control (grounded when locked, 12V power supply when unlocked)
[0191] (5) Positive and negative control (12V power supply when locked, grounded when unlocked)
[0192] Embodiment 1 corresponds to (1) negative control, and Embodiment 3 corresponds to (2) positive con...
