To provide a speed control device for a vehicle achieving smooth speed control with less discomfort of a driver according to intention of acceleration of the driver.
In vehicle speed control at a curve, a target vehicle speed Vto meeting the case when the driver carries out no accelerating operation (accelerating operation quantity Ap=0) is decided according to characteristics constructed of first, second and third target vehicle speeds Vto1, Vto2 and Vto3. The first target vehicle speed Vto1 is reduced until reaching a point Pcr and becomes an appropriate vehicle speed Vqo at the point Pcr. The second target vehicle speed Vto2 is kept at the appropriate vehicle speed Vqo from the point Pcr to a point Pca. The third target vehicle speed Vto3 is characterized to be increased from the point Pca to a point Pcs. Based on the accelerating operation quantity Ap by the driver, a correction vehicle speed Vz is computed, and during the control, a target vehicle speed Vt(=Vto+Vz) is decided by adding the correction vehicle speed Vz to the target vehicle speed Vto. A vehicle speed is regulated not to exceed the target vehicle speed Vt.
