Speed change control system for vehicle
A speed change control system for a vehicle configured to reduce uncomfortable feeling of a driver when shifting an operating mode via the fixed mode. When a required drive force to propel the vehicle is increased, a controller shifts the operating mode from a first continuously variable mode to a second continuously variable mode via a fixed mode. In this case, the controller increases an engine speed to a first target speed from a point when shifting from the fixed mode to the second continuously variable mode, and further increase the engine speed to a second target speed calculated based on the required drive force. In addition, the controller reduces the first target speed with an increase in at least any one of a first elapsed time and a second elapsed time. |
