Motor vehicle on-board electrical system has circuit breaker between battery and starter to reversibly separate battery-starter connection if precrash sensing arrangement detects crash

摘要

The system has a battery (2), a starter (5), a generator (4) and a precrash sensing arrangement. The starter and the generator are connected together and a circuit breaker (3) is arranged between the battery and starter for reversible separation of the connection between the battery and the starter if the precrash sensing arrangement detects a crash. Independent claims are also included for the following: a method of protecting a starter lead in a motor vehicle on-board electrical system.
