摘要： PURPOSE: To make a tibia moment not act on a shin part by preventing that an angle between a foot and the shin part becomes smaller than that at the time of usual traveling caused by a head-on collision, through a simple structure. CONSTITUTION: A front end of a car room 1 is composed of a floor face 2a, a toe board surface 3a rising forward aslant, and a dashpanel 4. A lower mounting piece 5b of a footrest 5 is clamped to the floor face with a mounting bolt 6. The upper part of a body 5a is supported from the toe board surface to the rear with a gap 8 between via an engaging means 7 which is composed of a pin member 7a and a support member 7c, and in an engaged state at usual time, it coms into contact with a peripheral surface of this pin member and supported on the support member, while in time of a collision from the front, the pin member is slidden forward by rear displacement of the support member with the rising deformation of toe board surface, thereby forming an incline 7e relatively shifting the body 5a to the toe board side.

摘要： PURPOSE:To restrict the shock due to a speed change by properly controlling the released state of a first friction element. CONSTITUTION:Learning control by a releasing pressure learning controlling means 200C is exercised on the releasing oil pressure of a first friction element on the releasing side, at the time of speed change when the first friction element is released and a second friction element is fastened, based on a difference between a target speed changing time, which is set by a target speed changing time setting means 200A, and actual speed changing time, which is detected by a speed changing time detecting means 200B. Accordingly, the released state of the first friction element can be properly controlled, thereby restricting the shock due to the speed change. The target speed changing time is set, based on turbine torque. In addition, since the fastening oil pressure of the second friction element on the fastening side is controlled based on the variation in the number of revolutions on the input side of a transmission, the fastening timing of the second friction element can be properly controlled, thereby restricting a timing lag.

摘要： PURPOSE:To prevent deterioration of a convergence property of slip control due to response delay of supercharging limitation at the time when it is changed over to the slip control by the supercharging limitation in a supercharging region when it is transferred to the supercharging region by accelerating operation during the slip control by fuel cutting or an ignition delay angle in a non- supercharging region. CONSTITUTION:By detecting slip (S2) by speed difference between a driving wheel and a driven wheel, when slip is generated in a non-supercharging region, slip control by fuel stop and an ignition delay angle is carried out (S6), and when slip is generated in a supercharging region, slip is restrained by supercharging limitation by a by-pass control valve (ABV) (S5). However, in the case when it is transferred to the supercharging region during the slip control by the fuel stop or the ignition delay angle, by limiting supercharging, the slip control by the fuel stop and the ignition delay angle is continued.

摘要： PURPOSE:To make it possible to set the effective length of a resonant air intake passage longer by providing a pair of resonant air intake passages, connected to a pair of air intake manifolds located between banks, on one bank and extending a resonant air intake passage on the other bank in an output shaft direction and bending it. CONSTITUTION:In the case of a traverse V-type six-cylinder engine 1, an air intake member 13, comprizing a pair of No.1 and No.2 air intake manifolds 14a and 14b arranged in parallel to each other and along with banks 1a and 1b, is provided between the banks 1a and 1b. Each three No.1 and No.2 independent air intake pipes 16a and 16b are connected integrally onto the underside of the air intake manifolds 14a and 14b, respectively. A one end of a No.1 and No.2 resonant air intake pipes 22a and 22b is connected to a joint of the independent air intake pipes 16a and 16b connected to No.3 and No.5 cylinders 4c and 4e and No.4 and No.6 cylinders 4d and 4f, respectively, roughly on the upper surfaces of each air intake manifold 14a.

摘要： PURPOSE:To ensure a large service space for an ignition plug by disposing both aggregate intake paths offset above one bank to connect a throttle body to longitudinal ends of the both aggregate intake paths. CONSTITUTION:A path 21b communicating to cylinders 4b, d, f of a bank 1b to which both aggregate intake paths 21a, 21b are biased is deflected from the path 21a in the same direction as the cylinder of a bank 1a is deflected from that of the bank 1b. Hence, a distance between the path 21b and a throttle body 27 is shortened by that deflection to be equal to that between the path 21a and said body 27, so that the distribution of intake to the cylinders of both banks 1a, 1b is uniformalized and the rotational frequencies of resonance synchronization in both banks can coincide with each other. Also, an independent intake path 20b connected to the path 21b is bent to locate plug holes 5 of respective cylinders of the bank 1b in gaps between the paths 20b, so that a large service space for ignition plugs can be ensured between the paths 20b.

摘要： PURPOSE:To prevent a car speed from its rapid increase while contriving the improvement of startability by providing an increase correction limiting means which limits an increase correction by an intake air amount increase correcting means when a connection condition detecting means detects an engine to be placed in a connected condition to a power transmission system. CONSTITUTION:In a condition that an engine E is not connected to a power transmission system, when an engine speed detecting means A detects an engine speed to be not more than a predetermined value, an intake air amount increase correcting means B is actuated increasing an intake air amount by a predetermined value, engine output and an engine speed. Accordingly, a predetermined speed is ensured of the engine, when it is started. While by a connection condition detecting means C, when the engine is detected to be placed in a connected condition to the power transmission system, an increase correcting means D is actuated limiting an increase correction by the intake air amount increase correcting means B. Accordingly, even when the engine speed decreases to the predetermined value or less by disturbance of step difference or the like, an increase of the engine output is suppressed, and an increase of a car speed due to a response delay is avoided.
