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.

Speed change control system for vehicle

A control system for a hybrid vehicle configured to start an engine promptly during propulsion in an electric vehicle mode. Electric power generation resulting from cranking the engine by a first motor is greater in the first electric vehicle mode compared to a second electric vehicle mode. A controller that is configured to determines whether an acceptable input power to an electric storage unit is smaller than a threshold value. If the acceptable input power to the electric storage unit is smaller than the threshold value, selection of the first electric vehicle mode is inhibited.

Control system for hybrid vehicle

A vehicle control system configured to stabilize a behavior of a vehicle during turning by correcting a driving force or a braking force. The vehicle control system comprises a lateral acceleration detecting means detecting longitudinal acceleration acting in an axle direction of the vehicle Ve (step S); and a driving/braking force correcting means determining a changing amount Fctrl and a changing rate DFctrl of the correction based on the lateral acceleration Gy in case the running vehicle Ve is turned.
