  • Patent number: 8030881
    Abstract: A battery control system and method for a battery of a vehicle includes a battery for supplying electrical power to a plurality of loads of the vehicle and a controller that receives a battery signal representative of a condition of the battery, an ignition key signal representative of a state of an ignition key of the vehicle, and an engine signal representative of a state of an engine in the vehicle. The controller selectively electrically connects/disconnects the plurality of loads of the vehicle and the battery based on at least one of the battery signal, the ignition key signal, and the engine signal. An interface provides information on at least one of the battery and a connection state between the plurality of loads and the battery.
    Type: Grant

  • Patent number: 7912618
    Abstract: A battery protection system is provided in a vehicle having an ignition system for selectively starting and stopping an engine of the vehicle and an electrical system including an electrical load and a battery that selectively delivers electric current to said load via a first device that protects said load from receiving excessive current. The battery protection system includes: a second device that selectively connects and disconnects the load from the battery; and a controller that controls said second device in response to a detected number of ignition cycles.

  • Patent number: 6803765
    Abstract: In a system for detecting misfire for an internal combustion engine wherein ionization current that flows following the discharge current is detected and integrated during a period (gate) and occurrence of misfire of the engine is detected based on the integrated value, a processing delay circuit is provided which inputs at least one of the discharge current or the ionization current and based on the inputted current, delays starting of the period by a time point which is not earlier than termination of the discharge current. With this, the system is unaffected by fluctuation in ignition coil discharge period, various kinds of noise and the like, and can therefore ensure accurate misfire detection by preventing erroneous detection owing to such causes.
