    摘要： An apparatus is provided to estimate a gradient of a road surface on which a vehicle travels. The apparatus comprises acquisition, estimation, and compensation members. The acquisition member acquires at least one of acceleration of the vehicle calculated on changes in a travel speed of the vehicle and acceleration sensed from a force applied to the vehicle. The estimation means estimates the gradient of the road surface based on the acquired acceleration. The compensation member compensates the acquired acceleration in terms of influence of noise superposed on the acceleration, depending on an operational condition of the vehicle. The compensated acceleration is used by the estimation. The compensation is carried out by cutting off the noise by a filter, for example.

    摘要： An apparatus is provided for controlling acceleration of a vehicle to a target acceleration. In the apparatus, a target acceleration calculator calculates the target acceleration. A provisional acceleration setting unit sets a provisional target acceleration such that a change rate of the provisional target acceleration is limited to a target limitation value. The provisional target acceleration is used during a step during which the acceleration of the vehicle is changed to the target acceleration. A drive power calculator calculates a drive power to obtain the provisional target acceleration. In the provisional acceleration setting unit, an initial value of the provisional target acceleration depends on a running state of the vehicle.

    摘要： An object of the invention is to provide an acceleration control apparatus, according to which accuracy for feed-forward torque may not be decreased even when a calculating accuracy for an estimated-slope torque would be decreased. Reliability of estimated slope is calculated and feedback torque is corrected, in such a manner that a gain for a feedback control portion is increased when the reliability of the estimated slope becomes lower. It is, therefore, possible to compensate a possible decrease of the accuracy of the feed-forward torque by correcting the feedback torque in accordance with the reliability of the estimated slope.

    摘要翻译： 本发明的目的是提供一种加速控制装置，根据该加速度控制装置，即使估计倾斜力矩的计算精度降低，也可能不会降低前馈转矩的精度。 计算估计斜率的可靠性，并且以这样的方式校正反馈转矩，使得当估计斜率的可靠性变低时，反馈控制部分的增益增加。 因此，可以通过根据估计斜率的可靠性校正反馈转矩来补偿前馈转矩的精度的可能降低。
