Automobile vehicle door locking assembly and process for testing correct operation of a lock module of this assembly
View Patent ↗An automobile vehicle door locking assembly, intended to be fitted in a vehicle door, of the type including an electric lock module incorporating, first, an electronic board providing an interface connecting the lock module to a main electrical power supply and to a control of said lock module, and, secondly, back-up electrical power supply to supply the lock module in the event of a malfunction of the main electrical power supply, wherein the back-up electrical power supply include at least one electronic energy-storage component mounted on the electronic board, this component preferably being a supercapacitor.
1. Automobile vehicle door locking assembly fitted in a vehicle door, including an electric lock module ( 14 ) incorporating an electronic board ( 16 ) providing an interface connecting said lock module ( 14 ) to main electrical power supply means ( 18 , 20 ) and to means ( 22 to 26 ) of control of said lock module ( 14 ), and back-up electrical power supply means ( 28 ) to supply said lock module ( 14 ) in the event of a malfunction of said main electrical power supply means ( 18 , 20 ), wherein said back-up electrical power supply means ( 28 ) include at least one electronic energy-storage component ( 30 ) mounted on said electronic board ( 16 ), wherein said electronic energy-storage component ( 30 ) is permanently loaded by said main electrical power supply means in normal use, and
wherein said electronic energy-storage component ( 30 ) is a supercapacitor.
2. Door locking assembly according to claim 1 , wherein said back-up electrical power supply means ( 28 ) include at least two electronic energy-storage components ( 30 ) mounted in series.
3. Door locking assembly according to claim 1 , wherein said back-up electrical power supply means ( 28 ) include at least two groups of electronic energy-storage components ( 30 ), the electronic components of a given group being mounted in series and the two or more groups being mounted in parallel.
4. Door locking assembly according to claim 1 , wherein said back-up electrical power supply means ( 28 ) include at least one pair of electronic energy-storage components ( 30 ) mounted in parallel.
5. Door locking assembly according to claim 1 , wherein said back-up electrical power supply means ( 28 ) include at least two pairs of electronic energy-storage components ( 30 ), these pairs being mounted in series.
6. Door locking assembly according to claim 1 , wherein said electronic energy-storage components ( 30 ) have an energy density between 0.4 and 10 Wh/kg.
7. Door locking assembly according to claim 1 , wherein said electronic energy-storage components ( 30 ) have a maximum charging or discharging current between 1 and 10 A for a voltage between 0.8 and 14 V.
8. Door locking assembly according to claim 1 , wherein said electronic board ( 16 ) includes memorization means ( 34 ) which can be electrically supplied by said electronic energy-storage components ( 30 ) and in which is stored software designed to test the correct operation of said lock module ( 14 ).
9. Process for testing correct operation of a vehicle door locking assembly fitted in a vehicle door and including an electric lock module ( 14 ) incorporating an electronic board ( 16 ) providing an interface connecting said lock module ( 14 ) to main electrical power supply means ( 18 , 20 ) and to means ( 22 to 26 ) of control of said lock module ( 14 ), and back-up electrical power supply means ( 28 ) to supply said lock module ( 14 ) in the event of a malfunction of said main electrical power supply means ( 18 , 20 ), wherein said back-up electrical power supply means ( 28 ) include at least one electronic energy-storage component ( 30 ) mounted on said electronic board ( 16 ), wherein said electronic energy-storage component ( 30 ) is permanently loaded by said main electrical power supply means in normal use, and wherein said electronic energy-storage component ( 30 ) is a supercapacitor,
said process characterized in that the test is performed before electrical connection of said lock module ( 14 ) to said main electrical power supply means ( 18 , 20 ) and after electrical charging of said electronic energy-storage component ( 30 ), said test process using software stored in memorization means ( 34 ) electrically supplied by said electronic energy-storage component ( 30 ).
