PROBLEM TO BE SOLVED: To provide a speed control device for a vehicle capable of achieving smooth speed control when the vehicle passes a curve. SOLUTION: Inside the curve, a reference point Pcr serving as a standard of a point at which deceleration of the vehicle is finished, a reference point Pca serving as a standard of a point at which maintenance of vehicle speed is finished, and a reference point Pcs serving as a standard of a point at which acceleration restriction of the vehicle is finished are set. A relative distance Lvh# between an own vehicle position Pvh and the reference point Pc# is calculated respectively. A target vehicle speed Vto1 calculated based on the Lvhr is decided as a target vehicle speed Vto until the vehicle passes the PCr. After the vehicle passes the Pcr, a target vehicle speed Vto2 calculated based on the Lvha is decided as the target vehicle speed Vto. After the vehicle passes the Pca, a target vehicle speed Vto3 calculated based on the Lvhs is decided as the target vehicle speed Vto. When a driver carries out no accelerating operation, the vehicle speed is regulated not to exceed the target vehicle speed Vto in the own vehicle position. COPYRIGHT: (C)2010,JPO&INPIT
