    • PROBLEM TO BE SOLVED: To stabilize body attitude or vehicle characteristics by suppressing the influence of driver operation disturbance or road surface disturbance or the like. SOLUTION: Various vibrations on a body spring are estimated by a body vibration model, and a required engine torque equivalent to a required driving force is corrected so that pitching vibration being one of the vibrations of the body spring can be suppressed. Concretely, traveling resistance disturbance estimated by a front wheels traveling disturbance estimating part 2d is added to estimated driving shaft torque estimated by an estimated driving shaft torque calculating part 2b so that a current driving force can be calculated, and pitching vibration corresponding to the current driving force is calculated from the status equation and output equation of a driving model on the body spring. Then, a correction value for quickly turning the pitching vibration expressed with the output equation into zero is calculated, and a basic request engine torque calculated by a basic request engine torque calculating part 2a is corrected based on the correction value.

    • 要解决的问题:通过抑制驾驶员操作扰动或路面扰动等的影响来稳定身体姿态或车辆特性。 解决方案:通过身体振动模型估计身体弹簧上的各种振动,并且校正与所需驱动力相当的所需发动机扭矩,从而可以抑制作为身体弹簧的振动之一的俯仰振动。 具体地说,将由前轮行驶扰动推定部2d推定的行驶阻力扰动与由推定驱动轴转矩运算部2b估计出的推定轴转矩相加,使得能够计算出电流驱动力,并且对应于当前行驶的俯仰振动 力是从身体弹簧上的驾驶模型的状态方程和输出方程计算的。 然后,计算用于将由输出方程表示的俯仰振动迅速转为零的校正值,并且基于校正值校正由基本要求发动机扭矩计算部分2a计算出的基本要求发动机扭矩。 版权所有(C)2006,JPO&NCIPI
