Abstract
An injection control device includes: a booster circuit that boosts a battery voltage; a boosting control unit that performs boosting control on the booster circuit; a charge control setting unit that sets a charge prohibition time of the booster circuit for the boosting control unit; and a maximum time specification unit that specifies a maximum valve-closing detection time based on a valve-closing detection time.
Claims6
An injection control device configured to open and close a fuel injection valve by driving the fuel injection valve with a current to control fuel injection to an internal combustion engine, the injection control device comprising:
- a booster circuit configured to boost a battery voltage;
- a boosting control unit configured to perform boosting control on the booster circuit;
- a charge control setting unit configured to set a charge prohibition time of the booster circuit for the boosting control unit;
- and
- a maximum time specification unit configured to specify a maximum valve-closing detection time based on a valve-closing detection time,
- wherein
- the charge control setting unit is configured to set the maximum valve-closing detection time as the charge prohibition time for the boosting control unit.
An injection control device configured to open and close a fuel injection valve by driving the fuel injection valve with a current to control fuel injection to an internal combustion engine, the injection control device comprising:
- a booster circuit configured to boost a battery voltage;
- one or more processors;
- and
- a memory coupled to the one or more processors and storing program instructions that when executed by the one or more processors cause the one or more processors to at least:
- perform boosting control on the booster circuit;
- set a charge prohibition time of the booster circuit;
- and
- specify a maximum valve-closing detection time based on a valve-closing detection time;
- and
- set the maximum valve-closing detection time as the charge prohibition time for the boosting control unit.
