Electronic control unit and vehicle behavior control device
An electronic control unit which includes: a sensor board to which a sensor for detecting a predetermined physical quantity is attached; a control board which controls an operation of an electric part based on the physical quantity detected by the sensor; and a housing which accommodates the sensor board and the control board, wherein the housing has a first room for accommodating the electric part, a second room for accommodating the sensor board and the control hoard in a stacked condition, and a partition portion for separating the first room and the second room from each other, wherein a recess which is opened to the second room is formed in the partition portion, and a sensor accommodating portion for accommodating the sensor is formed using the recess.
1. A vehicle behavior control device comprising a base body having a brake fluid path formed therein, and an electronic control unit, the electric control unit comprising:
a sensor board to which a sensor for detecting a predetermined physical quantity is attached, wherein the sensor comprises an angular velocity sensor and an acceleration sensor;
a control board which controls a brake fluid pressure in the brake fluid path by controlling an operation of an electric part based on a behavior of a vehicle body detected by the sensor; and
a housing which accommodates the sensor board and the control board,
wherein the housing has a first room for accommodating the electric part, a second room for accommodating the sensor board and the control board in a stacked condition, and a partition portion for separating the first room and the second room from each other,
wherein a recess which is opened to the second room is formed in the partition portion, and a sensor accommodating portion for accommodating the sensor is formed using the recess,
wherein the sensor accommodating portion is enclosed by the sensor board directly contacting the partition portion, and
wherein the control board directly contacts the partition portion.
