Abstract: A control unit in an electronic control device includes: an activation mode information storage unit having a software area with a plurality of sides for storing software and activation mode information indicating whether a system is activated in a normal mode or a reprogram mode; and an activation side information storage unit storing activation side information indicating with which of the plurality of sides the system is activated in the normal mode. At least one of the activation mode information and the activation side information is updated according to a progress of reprogram. The system is activated based on the activation mode information and the activation side information.

Abstract: An electronic control system includes: a master controller that: receives an update program and an update information file including information related to a program update; and transfers the update information file and the update program; a sub-controller that: writes an update program into a first memory; and receives the update information file and the update program from the master controller; and a specific update execution unit that: stores specific update information related to a program update for a second memory; and writes an update program into the second memory. The sub-controller controls the specific update execution unit to write, according to the specific update information, an update program of a firmware into the second memory when the update information file indicates that the program update includes an update of the firmware.

Abstract: A link apparatus includes a cam plate, a lever and an accommodation member. The cam plate has a cam groove. The lever has a roller engaged with the cam groove and a pin which is inserted through a center of the roller so that the roller is rotatably supported on the pin. The accommodation member accommodates the cam plate and the lever. The accommodation member and the pin have a distance “A” therebetween. The roller has a thickness “B” along an axial direction of the pin. The value of the distance “A” is smaller than the value of the thickness “B”.

Abstract: A sleeve member of a movable unit has a first pressure receiving surface and a second pressure receiving surface. The first pressure receiving surface receives a first fluid pressure in an axial direction opposite to a biasing force of a spring, when a valve member closes a seat opening portion. The second pressure receiving surface receives a second fluid pressure in the same axial direction to a direction of the biasing force of the spring, when the valve member closes the seat opening portion. A first surface area and a second surface area are made to be equal to each other. Each of the first and the second surface areas is an area of a projected portion on a virtual plane perpendicular to the axial direction. Each of the projected portions is obtained when each of the first and the second pressure receiving surfaces is projected to the virtual plane.

Abstract: An exhaust gas recirculation device includes a housing including an inner wall defining an intake passage through which an intake air passes. The housing includes an outlet opening of an EGR gas provided in the inner wall, and a throttle valve positioned in the intake passage and generating a negative pressure at the outlet opening. The housing includes an intake air guide device provided in the housing and guiding the intake air, which has passed between the throttle valve and the inner wall of the housing, toward an axial center area of the intake passage. At least a part of the intake air guide device is positioned on an upstream side of the intake air with respect to the outlet opening.
