摘要： An automatic transmission control apparatus is provided with a brake switch, a brake fluid pressure detecting section, a range position detecting section, a neutral control section and a prohibiting section. The brake switch is configured to output an on-signal when a brake pedal is depressed and otherwise output an off-signal. The brake fluid pressure detecting section is configured to detect a brake fluid pressure corresponding to a brake pedal depression force. The range position detecting section is configured to detect if a traveling range of an automatic transmission is selected. The neutral control section is configured to start a neutral control that puts the automatic transmission into a neutral state when the brake fluid pressure detected by the brake fluid detecting section exceeds a start threshold value while the range position detecting section detects that the traveling range is selected, and to end the neutral control when the brake fluid pressure falls below an end threshold value while the neutral control is being executed, with the start and end threshold values being set to values that are higher than the brake fluid pressure occurring when the brake switch starts outputting the on-signal. The prohibiting section is configured to prohibit the neutral control from being subsequently started again, after the neutral control has been started by the neutral control section, regardless of the brake fluid pressure detected by the brake fluid pressure detecting section until the brake switch outputs the off-signal.

摘要： A hybrid electric vehicle has a first mode in which slippage of a clutch (CL2) between an electric motor (MG) and a driving wheel (RL,RR) is allowed and controlled by rotational speed control of the electric motor (MG) and a second mode in which the slippage of the clutch is allowed and controlled by rotational speed control of an engine (E). When the vehicle is stationary in the first mode, a controller reduces a control setpoint (P2*) of hydraulic pressure (P2) of the clutch from an initial point. The controller identifies a reference point of the control setpoint (P2*) with which actual output torque of the electric motor (MG) becomes unchanged with respect to the reduction of the control setpoint (P2*). Then, the controller increases the control setpoint (P2*) from the reference point at a higher gradient and then a lower gradient, and then sets the control setpoint (P2*) to a corrected point below the initial point and above the reference point.
