    • A drive control device is provided for a vehicle which has an automatic transmission and which is capable of setting a throttle opening independently of an accelerator opening. Herein, the drive control device detects a shift range and an engine speed, based on which prescribed controls are made with regard to a throttle and a clutch. That is, if the engine speed is higher than a predetermined engine speed value when the shift range is changed over from a non-running range (e.g., N range) to a running range (e.g., D range), the drive control device controls the throttle opening substantially in a fully closed state while controlling clutch oil pressure of a start-mode-engaged gear to be set at a predetermined oil pressure value which is greater than zero and at which the clutch does not have a torque transmission capacity. In addition, in a predetermined time after the engine speed becomes lower than the predetermined engine speed value, the drive control device maintains the throttle opening in the fully closed state while gradually increasing the clutch oil pressure of the start-mode-engaged gear so as to control the clutch to start an engagement operation. Thus, it is possible to ease an engagement shock of the clutch which occurs when the driver changes gears from the N range to the D range while depressing the accelerator pedal.
    • 为具有自动变速器的车辆提供驱动控制装置,其能够独立于加速器开度设定节气门开度。 这里,驱动控制装置基于对节气门和离合器进行规定的控制来检测换档范围和发动机转速。 也就是说,如果当变速范围从非行驶范围(例如,N档)切换到运行范围(例如,D档)时,如果发动机转速高于预定发动机转速值,则驱动控制装置控制 节气门开度基本上处于完全关闭状态,同时控制起动方式啮合齿轮的离合器油压设定在大于零的预定油压值,并且离合器不具有转矩传递能力。 此外,在发动机转速低于预定发动机转速值的预定时间内,驱动控制装置将节气门开度保持在全闭状态,同时逐渐增大启动模式啮合齿轮的离合器油压,从而 以控制离合器开始接合操作。 因此,可以减轻当驾驶员在按下加速器踏板的同时从N档向D档变速时发生的离合器的接合冲击。
