To achieve both prevention of oversteer and ensuring of a regeneration amount in a rear drive vehicle.SOLUTION: A vehicle transmission control device comprises: an engine 4; a motor 5; an automatic transmission 8; a friction brake system 3; and a control device (controller 20) which executes regenerative control to apply regenerative brake torque to rear wheels 2R through causing the motor to perform regenerative operation and variable speed control to variably change a transmission stage of the automatic transmission through outputting a variable speed signal according to a rotation speed of an input shaft to the automatic transmission while a vehicle is decelerated with brake force distributed to front wheels 2F and the rear wheels through the friction brake system. When determining an oversteer state of the vehicle with the regenerative control in execution, the control device: maintains the regenerative operation of the motor while increasing input torque of the input shaft of the automatic transmission so as to reduce the regenerative brake torque; and limits the transmission control between the input shaft and an output shaft for the automatic transmission.SELECTED DRAWING: Figure 15

    【課題】後輪駆動車両におけるオーバーステアの抑制と、回生量の確保とを両立させる。【解決手段】車両の変速制御装置は、エンジン4と、モータ5と、自動変速機8と、摩擦ブレーキシステム3と、モータに回生動作をさせることによって後輪2Rへ回生制動トルクを付与する回生制御、及び、入力軸の回転数に応じた変速信号を自動変速機へ出力することによって自動変速機の変速段を変える変速制御を、摩擦ブレーキシステムが前輪2F及び後輪へ制動力を分配している車両の減速中に実行させる制御器(コントローラ20)と、を備え、制御器は、回生制御中に、車両のオーバーステア状態を判定した場合には、回生制動トルクが減少するよう自動変速機の入力軸の入力トルクを増大しつつモータの回生動作を維持すると共に、自動変速機の入力軸と出力軸との間の動力伝達を遮断させる。【選択図】図15
