摘要： PROBLEM TO BE SOLVED: To provide a vehicle control device and a vehicle control method preventing the production of rattling noise from a drive system when a lock-up clutch is engaged.
SOLUTION: When the lock-up clutch provided in a torque convertor 300 is engaged, a 4WD_ECU 2000 increases a torque transmitted to a rear wheel 1100 by controlling an electronic control coupling 900. Thereby, since a driven gear is pushed to a drive gear in the drive system on the side of the rear wheel (for example, a transfer 500) including gears, it is possible to prevent impact of gears when the lock-up clutch is engaged. Accordingly, it is possible to suppress the production of rattling noise.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus for further correcting output of acceleration sensors for vehicles and capable of accurately correcting the drift errors of the acceleration sensors.
SOLUTION: On the basis of a gradient θ in the forward and the backward directions estimated by a road gradient estimation means (166), output of the acceleration sensors 90 and 92 is corrected at an acceleration correction means 168. Acceleration values from the acceleration sensors are thus advantageously and accurately corrected, in comparison with a conventional correction device which considers that a vehicle is linearly cruising, when the difference between right and left rotation speeds of the vehicle remains within a prescribed value and takes output values of the acceleration sensors 90 and 92 at the time as drift errors.

摘要： PROBLEM TO BE SOLVED: To provide a control device for a driving force distribution apparatus for a vehicle capable of realizing downsizing/light weight of a driving system.
SOLUTION: The control device of a driving force distribution apparatus for a vehicle includes a transmission torque determination means 104 (SA8) for determining whether or not transmission torque of a predetermined value or more is transmitted by operation of a coupling 24; and a transmission torque control means 114 (SA10 to SA12) for transmitting it such that the transmission torque becomes a value less than a predetermined value when it is determined that the transmission torque of a predetermined or more is transmitted by the transmission torque determination means 104. Therefore, it can be controlled such that excess torque is not transmitted to the driving system when the coupling 24 is quickly engaged in the state that a rotation speed ne of an engine is relatively high at the start of the vehicle.

摘要： PROBLEM TO BE SOLVED: To provide a control device of a torque distribution clutch for a vehicle whereby turning traveling-time control for performing torque distribution control at turning travel and ordinary traveling-time control for performing torque distribution control at linear travel is prevented from being repeatedly selected in a short time period. SOLUTION: When selection from turning traveling-time control to other torque distribution control is determined by a torque distribution control determination means 264, other torque distribution control is selected based on the fact that a predetermined time period passes after the determination by a torque distribution control selection delay means 266. Thus, frequent control mode switch whereby turning travel control for performing torque distribution control at turning travel, ordinary traveling-time control for performing torque distribution control at linear travel or starting-time control is repeatedly selected at a short time period is suitably solved in winding or slalom travel whereby right or left turning travel is repeatedly performed.

摘要： PROBLEM TO BE SOLVED: To suppress generation of the noise associated with the change of the speed change mode in a vehicular sub transmission of a vehicle in which the rotational force of an internal combustion engine is inputted via an automatic transmission with a torque converter.
SOLUTION: A lock mechanism 40 is provided on a fork shaft 17 which is connected to a motor 30 via a waiting mechanism 20 to displace a sleeve 16 in the extending direction of a rotary shaft of an output shaft 15 based on the driving force of the motor 30. The lock mechanism 40 regulates the displacement of the sleeve 16 in an engaged state with a spline 11a for a normal mode when changing the speed change mode, and a spiral spring 23 of the waiting mechanism 20 is deformed. On the other hand, the lock mechanism 40 releases its regulation when the spiral spring 23 is deformed over the predetermined amount. Thus, the sleeve 16 in a neutral state separate from the spline 11a for the normal mode is urged to a spline 14a side for the low-speed mode by the elastic force of the spiral spring 23.
