Title:
CONTROL APPARATUS FOR VEHICLE
Document Type and Number:
Japanese Patent JP2008184137
Kind Code:
A
Abstract:

To secure excellent driveability by enhancing consistency when using both deceleration increase control (for example, deceleration flex lock-up control) and vehicle speed adjustment control (for example, adjustable speed limiter control) in a control apparatus (3, 4) for a vehicle mounted with an automatic transmission 2.

The control apparatus (3, 4) for a vehicle, which can use both of a deceleration increase control and a vehicle speed adjustment control, inhibits execution of the deceleration increase control, when there is a possibility that hunting, in which execution and stop of the deceleration increase control are repeated, may be caused during the vehicle speed adjustment control. Even though deceleration processing and acceleration processing are repeated in the process of maintaining a vehicle speed in this way, this repeating can be stopped at an earlier stage than when the intervention of the deceleration increase control is allowed, for example, during the vehicle speed adjustment control so that the fluctuations in a vehicle speed and torque can be converged in a short period of time.
