METHOD FOR OPERATING A FEED PUMP WHICH OPERATES IN A PULSATING FASHION |
摘要 |
A method for operating a feed pump operating in a pulsating manner in a feed unit to feed a liquid operating substance in a feeding direction, is used in a motor vehicle. The feed pump has a feed piston and a drive coil for driving the feed piston. The feed unit has a pressure sensor downstream of the feed pump in the feeding direction. A voltage profile is firstly applied to the drive coil. A feed stroke of the feed piston is subsequently carried out in accordance with the voltage profile. In this context, a pressure profile in the feed unit downstream of the feed pump in the feeding direction is monitored. This pressure profile is subsequently evaluated. The voltage profile is subsequently adapted as a function of at least one characteristic property of the pressure profile. A motor vehicle having a feed pump is also provided. |
