Abstract

An electrical unit relaying between an electrical component and an electronic control unit which determines a target operating amount of the electrical component, includes a communication port connectable with a communication wire connected to the electronic control unit, a power supply port connectable with a power supply wire connected to an external power supply, a ground port connectable with a ground wire, and one or more electrical component ports capable of supplying electric power to the electrical component. The electrical unit receives a signal relating to the target operating amount from the electronic control unit through the communication port. Electric power for operation according to the target operating amount is supplied to the electrical unit through the power supply port. The electrical unit supplies the electric power for operation to the electrical component through the electrical component ports.

Claims

1. An electrical unit relaying between an electrical component and an electronic control unit which determines a target operating amount of the electrical component, the electrical unit comprising:

a communication port connectable with a communication wire connected to the electronic control unit;

a power supply port connectable with a power supply wire connected to an external power supply;

a ground port connectable with a ground wire;

one or more electrical component ports capable of supplying electric power to the electrical component; and

a switch port connectable with a signal wire connected to a switch relating to on/off of the electrical component.

wherein the electrical unit receives a signal relating to the target operating amount from the electronic control unit through the communication port,

wherein electric power for operation according to the target operating amount is supplied to the electrical unit through the power supply port,

wherein the electrical unit supplies the electric power for operation to the electrical component through the one or more electrical component ports,

wherein the electrical unit transmits a signal received through the switch port to the electronic control unit through the communication port, and

wherein the electronic control unit determines the target operating amount based on the signal received through the switch port.

2. The electrical unit according to claim 1,

wherein when the electrical component is a motor, the electrical unit supplies the electric power for operation to the motor through a full-bridge circuit having a half-bridge circuit, and

wherein when the electrical component is a load other than a motor, the electrical unit supplies the electric power for operation to the load through half-bridge circuit.

3. The electrical unit according to claim 1,

wherein the electrical unit is integrally molded with resin in a stat that the communication port, the power supply port, the ground port, the switch port, and the one or more electrical component ports are disposed on the same side of the electrical unit in an aligned manner.

4. The electrical unit according to claim 1, further comprising:

a connecting mechanism capable of directly connecting the electrical unit to the electrical component.
