Принадлежит: Denso Corp

A control apparatus is used in an onboard system provided to a vehicle. The onboard system includes an internal combustion engine and a power generator. The power generator generates power and supplies the generated power to an electrical load provided to the vehicle. An output torque of the internal combustion engine causes the vehicle to travel and causes the power generator to generate power. Based on a power supply request by the electrical load, the control apparatus controls the output torque of the internal combustion engine. In response to the output torque being increased based on the power supply request, the control apparatus causes the power generator to generate the power by the output torque, while restricting generated power during an initial period when the output torque is being increased.

In a control circuit for controlling a power converter that includes a switch, a power supply circuit outputs electrical power, and a command generator generates a switching command that controls switching operations of the switch, based on the electrical power output from the power supply circuit. A failure mode determiner executes a determination of whether which of failure modes has occurred in the power supply circuit, and outputs a result of the determination. A switch controller selectively executes, based on the result of the determination, a first switch control task and a second switch control task. The first switch control task forcibly shuts down the switch independently of the switching command, and the second switch control task enables the switching operations of the switch to be continuously controlled based on the switching command.

Load-driving circuit having two transistors switched for heat dissipation

Номер: US20090278572A1
Автор: Shouichi Okuda, Tomohisa Ose
Принадлежит: Denso Corp

A load-driving circuit supplies electric current to a load, such as a resistor of an airbag squib. The load-driving circuit includes high side and low side current control circuits, both connected in series. Each current control circuit is composed of a driving transistor, a resistor and a current mirror circuit for controlling operation of the driving transistor. The components in the load-driving circuit are positioned in an integrated circuit chip to generate different temperature gradients among the components. For example, the low side resistor is positioned close to the high side driving transistor, so that the low side resistor is heated by the high side driving transistor controlled under a constant current control. As the low side resistor is heated, the high side driving transistor is switched from the constant current control to a full-on control. In this manner, controls of both driving transistors are automatically switched thereby to avoid overheating of one of the driving transistors.
