Title:
A speed change controlling device of an automatic shift
Document Type and Number:
Japanese Patent JP5982766
Kind Code:
B2
Abstract:
A target shift stage comes to a high speed stage at t2, during reduction toward zero of a motor torque by an accelerator pedal releasing operation (reduction to zero of an accelerator pedal stroke amount STacc) from t1, and an up-shift request along with the torque reduction is generated. However, the shift request is not executed until t3 when a delay time TMs elapses after t2, but is executed for the first time at t3, and the automatic transmission is shifted up to a high speed stage from a current low speed stage selecting state. Therefore, even in the case that a request for increasing a motor regenerative torque is issued by a braking operation just after (t2 to t3) an up-shift request moment t2 in response to the torque reduction (the accelerator pedal releasing), the gear shift in response thereto is not generated, and it is possible to avoid generation of repeated gear shift of low speed stage high speed stage low speed stage for a short time.
