Abstract
A starter device (1) for an internal combustion engine (2) is provided that comprises an electric starter motor (3), a power supply (16), and an activating unit (4) for the starter motor (3). The activating unit comprises circuit-breaker electronics (6) and a control unit (5) for the circuit-breaker electronics (6). Sensors are provided to register physical parameters relevant to the starting power of the starter motor (3) in order to adapt the start characteristic line of the starter motor (3) in optimal fashion within permissible limit values of the physical parameters.
Claims11
A starter device for an internal combustion engine comprising
- an electric starter motor (3),
- a power supply (16) for the starter motor (3),
- an activating unit (4) for the starter motor (3),
- wherein
- the activating unit (4) comprises
- circuit-breaker electronics (6),
- a control unit (5), the control output (8) of which is connected to the control input (9) of the circuit-breaker electronics (6), and
- sensors (11, 12, 13, 15, 20) connected to the inputs (10) of the control unit (5) for registering physical parameters relevant to the starting power of the starter motor (3), wherein the control unit (5) optimizes—and maximizes, in particular—the start characteristic line (5) for activation of the starter motor (3) within the permissible limit values (E, M, K) of the physical parameters based on the parameters registered by the sensors (11, 12, 13, 15, 20).
