To provide a vehicle speed calculation device that can achieve both suppression of deviation between a vehicle body speed and a vehicle speed for control and deterioration in followability to change in the vehicle speed for control in various kinds of control in a vehicle using the vehicle speed for control, and a vehicular control device.SOLUTION: A vehicle speed calculation device comprises a vehicle sped calculation part 200 that calculates a vehicle speed V for control that is obtained by estimating a vehicle body speed which is a speed at which a vehicle is actually running, as a state variable that is used in controlling a steering device as a vehicular device that operates in order to exert various functions that are mounted on the vehicle. The vehicle speed calculation part 200 is configured to have an extraction function of extracting at least one wheel speed of a plurality of wheel speeds that is obtained from a wheel that is assumed to rotate under a situation where there is less influence which generates deviation between the one vehicle body speed and the one wheel speed, and a calculation function of calculating the vehicle speed V for control, on the basis of the at least one wheel speed extracted through the extraction function.SELECTED DRAWING: Figure 7

    【課題】車体速と、制御用車速との乖離を抑えることと、制御用車速を用いた車両における各種の制御での当該制御用車速の変化に対する追従性の低下抑えることとの両立を図ることができる車速演算装置、及び車両用制御装置を提供する。【解決手段】車速演算装置は、車両に搭載される各種の機能を実現させるべく動作する車両用装置としての操舵装置を制御する際に用いられる状態変数として、車両が実際に走行している速度である車体速を推定して得られる制御用車速Vを演算する車速演算部200を備えている。車速演算部200は、複数の車輪速のうちの車体速との間で乖離を生じさせる影響が小さい状況で回転していることが想定される車輪から得られる少なくとも一の車輪速を抽出する抽出機能と、抽出機能を通じて抽出した少なくとも一の車輪速に基づいて、制御用車速Vを演算する演算機能とを有するように構成されている。【選択図】図7
