This application claims the benefit of priority to Korean Patent Application No. 10-2021-0136927, filed on Oct. 14, 2021 in the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference.
The present disclosure relates to a mobility system and an update management method thereof, and more particularly, to a technique for effectively updating a battery-based mobility system.
With development of the vehicle industry, in-vehicle controllers are continuously developed to provide convenience to drivers, and these controllers are updated with software, etc. based on wireless communication.
In general, a controller of an internal combustion engine vehicle performs an update when vehicle starting is turned on. However, when the vehicle starting is not turned on, the update is carried out in a state where a battery thereof is sufficiently charged, and when the battery is not sufficiently charged, the update is not performed.
Recently, even in a battery-based vehicle (mobility system), controllers directly related to driving, as in an internal combustion engine vehicle, are difficult to update when starting is on, so the update is performed when the starting is off, and in this case, the update is interrupted or difficult problems occur due to a risk of battery discharge by performing the update only with a charged battery in a starting-off state.
The above information disclosed in this Background section is only for enhancement of understanding of the background of the disclosure, and therefore, it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art.

The processor 140 may process a signal transferred between components of the update management apparatus 100, and may perform overall control such that each of the components can perform its function normally.
The processor 140 may be implemented in the form of hardware, software, or a combination of hardware and software, or may be implemented as microprocessor, and may be, e.g., an electronic control unit (ECU), a micro controller unit (MCU), or other sub-controllers mounted in the vehicle.
When updating the first controller 500 and the second controller 600 among one or more controllers, the processor 140 may perform the update by using the first auxiliary battery 300. In addition, the processor 140 may perform the update by using the second auxiliary battery 400 when updating the third controller 700 among the one more controllers 500, 600, and 700.
When a battery capacity level of the first auxiliary battery 300 is smaller than a battery capacity level required for updating the first controller 500 and the second controller 600, the processor 140 may supplementally charge the first auxiliary battery 300 by using the driving system battery 200, and when the battery capacity level of the first auxiliary battery 300 is equal to or greater than the battery capacity level required for updating the first controller 500 and the second controller 600, may update the first controller 500 and the second controller 600.
When the battery capacity level of the first auxiliary battery 300 is smaller than the battery capacity level required for updating the first controller 500 and the second controller 600, the processor 140 may update the second controller 600 by using the second auxiliary battery 400 instead of the first auxiliary battery 300.
When an update importance level of the first controller 500 among the one or more controllers is higher than a predetermined reference value, the processor 140 may perform the update of the first controller 500 without interruption by using one of the first auxiliary battery 300 or the second auxiliary battery 400, having a battery capacity level that is greater than the battery capacity level required for the update of the first controller 500.
In the case where the first controller 500 among the one or more controllers cannot be updated while the vehicle is driving and the second controller 600 among the one or more controllers can be updated while the vehicle is driving, when the vehicle starts driving while the first controller 500 is updated in a stopped state of the vehicle, the processor 140 may stop the update of the first controller 500, and may perform the update of the second controller 600 first.
The driving system battery 200 may supply power for driving the mobility system 10.
The first auxiliary battery 300 and the second auxiliary battery 400 may supply power when the one or more controllers 500, 600, and 700 are updated. Although two auxiliary batteries are illustrated in

Referring to
Then, the update management apparatus 100 may determines which battery is used for each controller to receive power and to update it depending on a present state (e.g., a battery capacity level) of each of the batteries 200, 300, and 400, relative update importance of the controller, and whether the vehicle is driven (S102).
That is, the present state of each battery is the battery capacity level, and the update management apparatus 100 may determine whether the battery capacity level is sufficient to complete the update of the controllers. In particular, the update management apparatus 100 may determine a battery to supply power to each controller by using the relative update importance of the controller and the battery capacity level. In this case, when the relative update importance of the controller is high compared to other controllers, it indicates that the update must be completed to the end without interruption of the update in the middle when updating each controller. For example, in the case where the battery capacity level of the auxiliary battery 300 is 5 Ah, when the expected battery required for updating the first controller 500 is 7 Ah and the first controller 500 is a controller with high update importance, if power is supplied by using the first auxiliary battery 300 for the update of the first controller 500, the update may be stopped due to insufficient power in the middle. In this case, the first controller 500 is a controller of high importance that the update should not be interrupted, and in this case, it may be determined to supply power to the first controller 500 by using the second auxiliary battery 400 having a high battery capacity level instead of the first auxiliary battery 300.
In addition, in the case where the first controller 500 is a controller that can be updated only when the vehicle is stopped, the update of the first controller 500 may be controlled to be performed while the vehicle is stopped, and when the vehicle starts driving, the update of the controller that can be updated while the vehicle is driving may be controlled to proceed.
As such, the update management apparatus 100 may determine which controller receives power from which battery to perform the update based on the update importance of each of the controllers 500, 600, and 700 and priority depending on a driving condition of the vehicle.
The update management apparatus 100 receives power from the first auxiliary battery 300 to perform the update of the first and second controllers 500 and 600 (S103), and receives power from the second auxiliary battery 400 to perform the update of the third controller 700 (S104).
Referring to
Next, the update management apparatus 100 determines which battery is used to receive power and to perform the update depending on the present state of each of the batteries 200, 300, and 400 (S202). For example, the update management apparatus 100 may determine to receive power from the first auxiliary battery 300 and to perform the update of the first and second controllers 500 and 600, and to receive power from the second auxiliary battery 400 and to perform the update of the third controller 700.
In this situation, the update management apparatus 100 determines whether the battery capacity level of the first auxiliary battery 300 is insufficient to update the first and second controllers 500 and 600, when it is determined that it is insufficient, supplementally charges the first auxiliary battery 300 through the driving system battery 200, and when the battery capacity level of the first auxiliary battery 300 is charged more than a predetermined reference value, updates the first and second controllers 500 and 600 (S203).
In this case, the update management apparatus 100 receives power from the second auxiliary battery 400 to perform the update of the third controller 700 (S204).
Referring to
Next, the update management apparatus 100 determine which battery is used to receive power and to perform the update depending on the present state of each of the batteries 200, 300, and 400 (S302).
The update management apparatus 100 may control the power to be received from the second auxiliary battery 400 instead of the first auxiliary battery 300 to update the second controller 600 (S303) when it is determined that the battery capacity level is insufficient for the first auxiliary battery 300 to update the first and second controllers 500 and 600 in a situation where it is determined to receive power from the first auxiliary battery 300 and to perform the update of the first and second controllers 500 and 600, and to receive power from the second auxiliary battery 400 and to perform the update of the third controller 700.
Referring to
In this case, the second controller 600 needs the battery capacity level of 7 Ah for the update, but the current battery capacity level of the first auxiliary battery 300 is 5 Ah, and thus when the update is performed by receiving power from the first auxiliary battery 300, the second controller 600 has no choice but to stop the update because power supply is cut off during the update.
Accordingly, the update management apparatus 100 controls the power to be received from the second auxiliary battery 400 with a sufficient battery capacity level and to update the second controller 600 (S401). Accordingly, the second controller 600 may perform the update without interruption of the update.
Referring to
The update management apparatus 100 performs an update of the second controller 600 in a vehicle stop state (S401).
Thereafter, the update management apparatus 100 monitors a moving state of the vehicle, when the vehicle is changed from a stopped state to the moving state (S502), cannot continue to update the second controller 600, and stops updating the second controller 600 and changes the order to update the third controller 700 first (S503).
In this case, although the second controller 600 was receiving power from the first auxiliary battery 300, the power supply is changed to be performed by the second auxiliary battery 400 for the update of the third controller 700 (S504).
As such, according to the present disclosure, it is possible to perform update by determining a battery for supplying power to each controller based on the battery capacity level, the relative update importance of the controller, and the vehicle driving state. Further, according to the present disclosure, it is determined whether the update of the controller is possible based on the current battery capacity level and, if not possible, the update may be controlled to be started after supplementally charging from the drive system battery, or the update may be started after the battery to supply power for the update of the controller is changed to a battery with sufficient battery charge. In addition, according to the present disclosure, the update order of the controller may be changed depending on the driving state of the vehicle.
