摘要:
Disclosed is a damping force control device for a vehicle that controls the damping coefficient of a damping force generation device on the basis of a final target control amount that is based on the target control amount for attitude control, which suppresses changes in the vehicle body attitude in at least the rolling direction, and the target control amount for riding comfort control, which increases riding comfort with regards to vehicle body vibrations in at least the rolling direction. The target control amount for riding comfort control is a control amount calculated as the total of a fixed basic control amount and a variable control amount. The target control amount and the variable control amount for attitude control are calculated, a post-correction basic control amount, which is nearer to the target control amount for attitude control than the basic control amount, is calculated, and the total of the post-correction basic control amount and the variable control amount is set as the final target control amount, thereby excellently achieving both the suppression of attitude changes and an increase in riding comfort.

摘要:
A vehicle control device includes a spring mechanism configured to connect a sprung member and an unsprung member of a vehicle, generate a spring force according to a relative displacement between the sprung member and the unsprung member, and be able to variably control the spring force, and a damping mechanism configured to connect the sprung member and the unsprung member, generate a damping force for damping a relative motion between the sprung member and the unsprung member, and be able to variably control the damping force, wherein the spring mechanism and the damping mechanism are controlled based on a first physical quantity relating to a sprung vibration of the vehicle and a second physical quantity relating to an unsprung vibration of the vehicle.

摘要:
A corrected state space model obtained by correcting a state space model to represent a controllable system by adding an error matrix Δ to a state space model representing an uncontrollable system is designed. A control object is controlled based on a control input of the system represented by this corrected state space model. The control input is calculated by a state feedback controller. By correcting the state space model representing the uncontrollable system by the error matrix Δ, the system can be made controllable. Since the error matrix Δ is added to a state matrix, an influence of an error on an output of the system can be reduced.

An electric wire with terminal includes an electric wire covering an outer periphery of a core wire with an insulating coating and a female terminal. The female terminal includes: a wire barrel having a bottom plate on which the core wire is placed and crimped onto the core wire; a groove portion extending from the bottom plate in a direction in which the core wire extends and whose surface on the side where the core wire is placed is bent into a concave shape. The groove portion has a water blocking wall molded by synthetic resin. The water blocking wall is provided to fill the inside of the groove portion. A region extending from the water blocking wall to the end of the insulating coating is covered with a water blocking coating, and the inner surface of the water blocking coating is in close contact with the water blocking wall.

Each of a plurality of auxiliary connector (10) includes an auxiliary housing (11), a seal (40) attached to the rear of the auxiliary housing (11), and a rear holder (50) mounted on the rear of the seal (40) to retain the seal (40). Auxiliary connectors (10) that are adjacent in an arranging direction are united by the rear holders (50). The united auxiliary connectors (10) are inserted into a frame (60) in the arranging direction through an insertion opening (60A) of the frame (60), and are retained in the frame (60) by engaging a lock (50B) on the last auxiliary connector (10A) and an interlocking portion (61) of the frame (60). The frame (60) has no partition walls between the auxiliary connectors (10). Thus, the connector is narrowed by a total thickness of the partition walls.
摘要:
A female housing (20) made of a synthetic resin is formed with cavities (22) for accommodating female terminal fittings (21), and locks (24) engageable with the female terminal fittings (21) to retain them are provided in the cavities (22). Each lock (24) projects from an outer surface (20a, 20b) of the female housing (20) during resilient deformation. A lock arm (40) for holding a mating male connector (M) in a connected state is mounted on the female housing (20). The lock arm (40) is made of metal and includes a press-in portion (42) that can be pressed into press-in grooves (30) of the female housing (20). The lock arm (40) is arranged to face the locks (240) and can be retracted into deformation spaces (330) for the locks (240) during the resilient deformation.

A rubber plug (10) has a main body (11) with opposite front and rear ends. A wire insertion hole (12) extends through the main body (11) from the rear end to the front end and has a wire-introducing opening (14) at the rear end. A forwardly and inwardly tapered portion (18) is formed on the outer circumferential surface of the main body (11) at the front end and a fastening portion (17) is rearward of the tapered portion (18). Protrusions (19) project radially out at the front end of the main body (11). The maximum outer diameter of the front end, including the protrusions (19), exceeds the inner diameter of the wire-introducing opening (14) at the rear end of the main body (11) and is no greater than the minimum outer diameter of the fastening portion (17).
摘要:
A connector has a housing (10) formed with cavities (11) for receiving male terminal fittings (40). Each cavity (11) has a receiving surface (16) substantially normal to an inserting direction of the male terminal fitting (40), and each male terminal fitting (40) has a contact surface (50) substantially normal to the inserting direction. The inserted male terminal fitting (40) is stopped at a front-limit position by bringing the contact surface (50) thereof into contact with the receiving surface (16) in the cavity (11) substantially in the same direction as the inserting direction of the male terminal fitting (40). Thus, the male terminal fitting (40) can be stopped at a proper insertion position.
