CONTROL APPARATUS FOR CONTROLLING ON-VEHICLE STARTER FOR STARTING ENGINE
First Claim
1. A control apparatus for controlling a starter used to start an engine mounted on a vehicle, the starter generating a torque for starting the engine and having a first gear outputting the generated torque, the engine having a second gear to receive the torque, the first gear mechanically engaging with the second gear to start the engine, the control apparatus comprising:
- a trigger circuit adapted to output a trigger signal in response to a start request;
a detection circuit adapted to detect an overall state of the starter which comprises an electrical state and a mechanical state of the starter while the starter is powered on; and
a controller including first means configured to power on the starter in response to the trigger signal outputted by the trigger circuit, and second means configured to power off the starter when the controller detects that a predetermined condition of the starter is satisfied based on the overall state of the starter.

Abstract
A control apparatus for controlling a starter used to start an engine mounted on a vehicle, the starter generating a torque and having a first gear mechanically engaged with a second gear of the engine to start the engine. The control apparatus includes a trigger circuit adapted to output a trigger signal in response to a start request; a detection circuit adapted to detect an electrical state and a mechanical state of the starter while the starter is powered on; and a controller adapted to control power on and off of the starter. The controller powers on the starter in response to the trigger signal outputted by the trigger circuit, and powers off the starter when the controller detects that a predetermined condition is satisfied based on the state of the starter.

11. A control apparatus for controlling a starter used to start an engine mounted on a vehicle, adapted to an automatic stop/restart system where an engine is controlled to be stopped when an automatic stop condition is met and restarts when a predetermined start condition is met, the starter generating a torque for starting the engine and having a first gear outputting the generated torque, the engine having second gear to receive the torque, the first gear mechanically engaging with a second gear to start the engine, the control apparatus comprising:
-
a trigger circuit adapted to output a trigger signal in response to a start request; a detection circuit adapted to detect an electrical state and a mechanical state of the starter while the starter is powered on; and a controller adapted to control power on and off of the starter; wherein the controller powers on the starter in response to the trigger signal outputted by the trigger circuit, and powers off the starter when the controller detects that a predetermined condition is satisfied based on the state of the starter.
