Abstract
A transmission system for vehicle includes a clutch disposed in a power transmission path between an engine and a vehicle wheel, a transmission disposed in the power transmission path, a clutch actuator, a shift actuator, a vehicle wheel speed sensor, a sudden deceleration detecting unit that detects a sudden deceleration of the vehicle wheel based on an output signal of the vehicle wheel speed sensor, and a shift control unit. The shift control unit executes an ordinary shift control to shift to a speed adaptive shift stage associated with the rotational speed and to execute, when the sudden deceleration detecting unit detects the sudden deceleration of the vehicle wheel, a sudden deceleration adaptive shift control to shift to a shift stage lower than an actual shift stage at the point of detection of the sudden deceleration and higher than the speed adaptive shift stage associated with the rotational speed.
