Abstract
Methods and systems are provided for operation of a lifting mechanism coupled to a mobility service vehicle. In one example, a method may include, during an engine idle-stop, in response to a request for operation of a lifting mechanism used by mobility devices to access the vehicle, the transmission may be shifted to park, an electronic braking system may be enabled, and the engine may be restarted to provide power for operation of the lifting mechanism.

11. A vehicle method, comprising;
-
during a first engine restart condition, responsive to a request for operating a lifting mechanism, restarting an engine with a transmission in park and an electronic parking brake enabled before operating the lifting mechanism; and during a second engine restart condition, responsive to a request for operating an air-conditioning system, restarting the engine with the transmission in drive and the electronic parking brake disabled before operating the air-conditioning system. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A vehicle system comprising:
-
a vehicle including a vehicle cabin; a lifting mechanism coupled to the vehicle cabin; a hydraulic system coupled to the lifting mechanism; a dashboard including a switch electronically coupled to the lifting mechanism; a powertrain including an engine and a transmission, the engine coupled to an electric motor; an air-suspension system; a mechanical parking brake; an electronic parking brake; an air-conditioning system; and a controller with computer readable instructions stored on non-transitory memory for; in response to the switch being activated to request operation of the lifting mechanism while the engine is at rest in idle-stop; shifting the transmission from drive to park; enabling the electronic parking brake to bring the vehicle to rest; restarting the engine by cranking the engine via the electric motor; operating the lifting mechanism via the hydraulic system after engine speed is above a threshold speed; and upon completion of the operating, shutting down the engine and returning the engine to idle-stop. - View Dependent Claims (19, 20)
