Abstract: A solenoid control apparatus includes a resin housing having a solenoid mounting portion, a connector portion, and a circuit board mounting portion in which a circuit board is mounted. Terminals extending from the solenoid mounting portion and the connector portion are soldered to the electrical circuit on the circuit board. The circuit board has a reduced-rigidity portion in its area corresponding to a portion of the resin housing through which the connector portion is connected to the solenoid mounting portion. The reduced-rigidity portion is formed by reducing the amount of material forming the circuit board per unit area, and is more easily deformable than the remaining portion of the circuit board. When the connector portion is thermally deformed, the circuit board is also easily deformable about the reduced-rigidity portion. This reduces stress on the soldered portions.

Abstract: There is provided a low-cost, power-saving brake control apparatus that is capable of performing control with good pressure regulation precision.

Abstract: In a brake hydraulic pressure control device, a main ECU is provided with a first converter for converting serial signals or parallel signals inputted thereto into parallel signals or serial signals to output the converted signals, while a motor ECU arranged away from the main ECU is provided with a second converter for converting serial signals or parallel signals inputted thereto into parallel signals or serial signals to output the converted signals. The first and second converters are electrically connected with each other through at least one conductive member capable of serial communication.

Abstract: In a braking pressure control unit for a vehicle braking system, an electric motor is arranged at one side of a hydraulic pressure control block, while electromagnetic valves and an electronic control unit are arranged at the other side of thereof. A connector portion to be connected with an external terminal and an accommodation space are formed in a casing of the braking pressure control unit, such that the connector portion and the accommodation space protrude outwardly from an outer periphery of the hydraulic pressure control block in a direction perpendicular to a direction of a motor shaft of the electric motor, and that the accommodation space is neighboring to the connector portion. And a large-sized electrical part included in a motor driving circuit is accommodated in the accommodation space.
