PROBLEM TO BE SOLVED: To provide a control system for working vehicle, working in such a way that a torque is calculated based on engine revolutions and fuel injection levels and torque variations are sensed in making a work, and when the torque variations come to a predetermined mode, it is judged that a slip occurred, thus making a control ensuring such a slip not to occur, in view of the fact that accurate load variations have been unable to be sensed so far. SOLUTION: In a working vehicle loaded with a diesel engine equipped with an electronically controlled fuel injector and a means for calculating injection level for each cycle, there are also equipped a means 33 to detect the revolution of the crank shaft 25 of the engine, a working implement 7, an injection level control means for the fuel injector, a working implement lift control means and a working vehicle speed control means. The control system for the working vehicle works as follows: An engine torque is calculated based on fuel injection levels and engine revolutions, and it is judged that a wheel slip occurred when there is a sharp torque decrease following a sharp torque increase within a predetermined time discretionarily set in advance and the torque is sustained for a discretionarily set time.
