Preventing automatic leveling during battery replacement
The invention refers to a method of preventing automatic leveling during battery replacement, and a computer-program thereof. The method of preventing automatic leveling during battery replacement, according to invention, operates for an electric vehicle equipped with a first electronic control unit ( 100 ) in charge with battery replacement and a second electronic control unit ( 200 ) of suspension system, the respective ECUs ( 100, 200 ) communicating by means of an internal bus system. The method includes the following steps: ( 51 ) Sending an information from the first ECU to the second ECU that the vehicle is prepared to perform a battery replacement; ( 52 ) Once said information is received by the second ECU, triggering a leveling forbid flag to the suspension system and deactivating it; ( 53 ) Once said deactivation has been performed, setting a feedback signal to inform that battery replacement can commence; ( 54 ) during battery replacement, setting said feedback signal to inform that battery replacement is ongoing; ( 55 ) Upon completion of battery replacement, informing the second ECU that the battery replacement has been finished successfully, and allowing the activation of suspension.
1. A method of preventing automatic leveling during battery replacement, operating for an electric vehicle equipped with a first electronic control unit in charge with batter replacement and a second electronic control unit of a suspension system, the first electronic control unit and the second electronic control unit communicating by means of an internal bus system, the method comprising:
sending information from the first electronic control unit to the second electronic control unit that the vehicle is prepared to perform a battery replacement;
in response to the information received by the second electronic control unit, triggering a leveling forbid flag to the suspension system and deactivating the automatic leveling;
in response to deactivating the automatic leveling, setting a feedback signal to inform that battery replacement can commence;
during battery replacement, setting said feedback signal to inform that battery replacement is ongoing; and
in response to completion of battery replacement, informing the second electronic control unit that the battery replacement has been finished successfully, and activating the automatic leveling.
2. The method according to claim 1 , wherein deactivating the automatic leveling comprises temporarily blocking all leveling and pressure compensations of the suspension system.
3. The method according to claim 2 , wherein the activating comprises triggering a pressure compensation.
4. A non-transitory computer-readable recording medium having embodied thereon a computer program that when executed by a first electronic control unit and a second electronic control unit causes an electric vehicle equipped with a first electronic control unit in charge with battery replacement and a second electronic control unit of a suspension system, the first electronic control unit and the second electronic control unit communicating by means of an internal bus system, to perform a method of preventing automatic leveling during battery replacement, the method comprising;
sending information from the first electronic control unit to the second electronic control unit that the vehicle is prepared to perform a battery replacement,
in response to the information received by the second electronic control unit, triggering a leveling forbid flag to the suspension system and deactivating the automatic leveling;
in response to deactivating the automatic leveling, setting a feedback signal to inform that battery replacement can commence;
during battery replacement, setting said feedback signal to inform that battery replacement is ongoing; and
in response to completion of battery replacement, informing the second electronic control unit that the batter replacement has been finished successfully, and activating the automatic leveling.
