PROBLEM TO BE SOLVED: To provide a control device of an all-wheel drive vehicle, which can shorten a time until execution of discharge of a smoothing capacitor to improve safety in a vehicle collision.SOLUTION: A control device 30 is for an all-wheel drive vehicle which comprises: an electric motor 3; a capacitor 38; a clutch which adjusts power to be transmitted to one wheels (for instance, rear wheels) of front and rear wheels according to fastening force; a first power transmission mechanism which mechanically connects between the one wheels and the electric motor 3 via the clutch and transmits power; and a second power transmission mechanism which mechanically connects between the other wheels (for instance, front wheels) and the electric motor 3 and transmits power. The control device comprises collision detection means 34 for detecting a collision of the vehicle, rotation speed detection means 31 for detecting rotation speed of the electric motor 3, and control means 35, 36 which, when a collision is detected, performs increase control on the fastening force of the clutch, and when rotation speed of the electric motor 3 becomes below a predetermined value after start of the increase control, carries out discharge of the capacitor 38.SELECTED DRAWING: Figure 2 【課題】車両衝突時の安全性を向上させるために、平滑用コンデンサの放電実施までの時間を短くできる全輪駆動車両の制御装置を提供する。【解決手段】電動モータ３と、コンデンサ３８と、前後輪のうちの一方の車輪（例えば、後輪）に伝達される動力を締結力に応じて調節するクラッチと、一方の車輪と電動モータ３との間をクラッチを介して機械的に連結して動力を伝達する第１動力伝達機構と、他方の車輪（例えば、前輪）と電動モータ３との間を機械的に連結して動力を伝達する第２動力伝達機構とを備える全輪駆動車両の制御装置３０である。車両の衝突を検知する衝突検知手段３４と、電動モータ３の回転数を検出する回転数検出手段３１と、衝突を検知した場合、クラッチの締結力の増加制御を行い、増加制御開始後に電動モータ３の回転数が所定値以下になるとコンデンサ３８の放電を実施する制御手段３５、３６とを備えることを特徴とする。【選択図】図２
