Title:
内燃機関に設けられている負圧アキュムレータを駆動する方法、コンピュータプログラム、および制御装置
Document Type and Number:
Japanese Patent JP5311701
Kind Code:
B2
Abstract:
Described are a method, a computer program, and a control unit for operating a vacuum reservoir (6) provided in an internal combustion engine of a motor vehicle for a servo booster or power-assist unit (8, 10, 11) of the internal combustion engine, which is coupled to an intake manifold (1) of the internal combustion engine and to an electrical suction pump (30). The pressure prevailing in the vacuum reservoir (6) is determined by a computational model in which quantity flows are fed to the vacuum reservoir (6) when at least one servo unit (8, 10, 11) is actuated, quantity flows are removed from the vacuum reservoir (6) when the pressure prevailing in the intake manifold (1) is lower than the pressure prevailing in the vacuum reservoir (6), i.e., when the electrical suction pump (30) is switched on. The total pressure prevailing in the vacuum reservoir (6) is calculated from the balance of these flow quantities.
