ABSTRACT:
Engine-racing control is performed in which a throttle valve is temporarily driven to the open side at start of cruise control. The engine-racing control is forcibly stopped when skip vehicle speed Vsk serving as an estimated vehicle speed after a predetermined time becomes higher than storage vehicle speed (target traveling speed) Vm. For example, on a downward slope where a vehicle is naturally accelerated due to gravitational acceleration, the vehicle is excessively accelerated due to the engine-racing control same as that on a flat road. However, because the behavior of the vehicle on the downward slope is reflected on the skip vehicle speed Vsk, it is possible to stop the engine-racing control early compared to the case in which the vehicle travels on the flat road and to avoid excessive acceleration.
