    • A start-up controller of an engine includes a shift-position detector (32), a first setter (4a) and a limit controller (5).
      The shift-position detector (32) detects whether a position (R NG ) of a select lever of an automatic transmission (26) is in a driving range.
      The first setter (4a) determines a limit rotation rate (Ne LIM_H ) based on the position (R NG ) detected by the shift-position detector (32) at start-up of the engine (10) as a limit of the rotation rate of engine. The limit rotation rate (Ne LIM _ H ) is determined lower when the position (R NG ) is in the driving range compared to when the position (R NG ) is not in the driving range.
      A limit controller (5) performs limit control for controlling the actual rotation rate (Ne) of the engine so as not to exceed the limit rotation rate (Ne LIM _ H ) determined by the first setter (4a).
      Such a configuration prevents revving-up of the engine at start-up while improving the start-up performance.
    • 发动机的启动控制器包括档位检测器(32),第一设定器(4a)和限制控制器(5)。 档位检测器(32)检测自动变速器(26)的选档杆的位置(RNG)是否处于行驶档位。 第一设定器(4a)基于由发动机(10)启动时由档位检测器(32)检测的位置(RNG)确定限制转速(NeLIM_H)作为发动机转速的极限 。 与当位置(RNG)不在行驶范围内时相比,当位置(RNG)处于行驶范围时,限制转速(NeLIM_H)被确定为较低。 限制控制器(5)执行限制控制以控制发动机的实际转速(Ne),使其不超过由第一设定器(4a)确定的极限转速(NeLIM_H)。 这种配置可以在启动时防止发动机加速,同时提高启动性能。
