1. A control device for controlling an engine based on an operating state of a vehicle, comprising:

  • a steering angle detector for detecting a steering angle of a steering wheel;

    a slip controller for acquiring the steering angle from the steering angle detector, detecting a slip state of wheels of the vehicle based on a part of the operating state of the vehicle including the acquired steering angle, and determining a torque control amount based on the detected slip state;

    a power train controller provided with a basic target torque determining module, a torque reduction amount determining module, a final target torque determining module, and an engine controlling module; and

    a processor of the power train controller configured to execute;

    the basic target torque determining module for determining a basic target torque based on the operating state of the vehicle including an operation of an accelerator pedal;

    the torque reduction amount determining module for determining a torque reduction amount based on a steering speed calculated from the acquired steering angle obtained by the steering angle detector, the torque reduction amount determined when the steering speed exceeds a predetermined threshold;

    the final target torque determining module for determining a final target torque based on the basic target torque, the torque reduction amount, and the torque control amount obtained by the slip controller; and

    the engine controlling module for controlling the engine to output the final target torque.
