The invention discloses a vehicle speed calculation apparatus and a control apparatus for a vehicle. A vehicle speed calculation device includes a vehicle speed calculation unit (200) configured to calculate a control vehicle speed obtained by estimating a vehicle body speed as a speed at which the vehicle is actually traveling, as a state variable for controlling an in-vehicle device configured to operate to implement various functions provided in the vehicle. The vehicle speed calculation unit (200) is configured to include: an extraction function that extracts, from among wheel speeds of a plurality of wheels, at least one wheel speed obtained from at least one wheel that is assumed to rotate in a state in which an influence that causes a difference from a vehicle body speed is likely to be small; and a calculation function that calculates a control vehicle speed based on the at least one wheel speed extracted by the extraction function.
本发明公开了车速计算装置和用于车辆的控制装置。一种车速计算装置包括车速计算单元(200),该车速计算单元(200)被配置成计算通过估计作为车辆实际行驶的速度的车体速度而获得的控制车速,作为用于控制车载装置的状态变量,该车载装置被配置成进行操作以实现设置在车辆中的各种功能。车速计算单元(200)被配置成包括:提取功能,其从多个车轮的车轮速度当中,提取从被假定为在下述影响可能小的状态下旋转的至少一个车轮获得的至少一个车轮速度,该影响引起与车体速度的差;以及计算功能,其基于通过提取功能提取的至少一个车轮速度来计算控制车速。
