As shown, the method in Box 312 comprises providing a portable child seat 20 designed to be secured in the vehicle 14 (generally Box 212, identification of the stationary vehicle seat). According to this example, the method implements the system 10 discussed above. Fig. 1, which the in the Fig. Includes the portable child car seat shown in 2-6.

[0067] In Fig. 12. The procedure further includes, in Box 314, the identification of a stationary vehicle seat 40 in the vehicle when a request to activate the child seat locking arrangement is received (generally Box 212, Identification of the stationary vehicle seat). According to this example, the procedure implements the above discussed and described in the Fig. The stationary vehicle seat 40 shown in Figures 1-6. As discussed above, the ECU 70 is designed to identify the stationary vehicle seat 40 in the vehicle when a request to activate the child seat locking arrangement is received. For example, the ECU 70 receives a booking ticket / signal or an activation request from the user device 74 via the cloud server 76 for a car trip and to activate the child seat locking arrangement / system. The user device 74 is preferably equipped with a global positioning system (GPS) for determining the location of a user via the user device 74.

[0068] According to one embodiment, the vehicle can include several stationary vehicle seats 40 that can be activated to engage with the portable child seat 20. The vehicle can, for example, include a first stationary vehicle seat located on one side (e.g., the left side) of the vehicle and a second stationary vehicle seat located on the other side (e.g., the right side) of the vehicle. In response to the requirement, the ECU 70 is designed to identify and select one of the several stationary vehicle seats 40 to be activated for engagement with the portable child seat 20, based on the GPS location of the user device 74 relative to the vehicle.
