Abstract: PROBLEM TO BE SOLVED: To avoid reduction in operation efficiency by continuing an operation as much as possible even in the case in which no control information required for performing a control by an information input means is not normally inputted. SOLUTION: When control information inputted by an information input means JN is normal, a control means CU carries out a treatment for repeatedly renewing and memorizing the control information in an information memory means RAM, performs an operation control based on the inputted control information. On the other hand, when the control information inputted by the information input means JN is not normal, the control means carries out the operation control based on the control information renewed and memorized in the information memory means RAM.

Abstract: PROBLEM TO BE SOLVED: To perform a proper control while eliminating a useless cost, in the case of making a central control part obtain information of sensor, etc., necessary for control, driving the whole actuators of each part of a machine body based on the information and concentrically controlling the whole working vehicle, by making the central control part communicate with a signal requiring a high-speed communication treatment and a signal not requiring a high-speed communication treatment by communication lines suitable for each communication. SOLUTION: Actuators AK for operation, sensors SW for detecting control information and an information obtaining means JN of a manual operation type are connected to any of plural terminal control parts LU and MU distributed and arranged at each part of a machine body. A terminal control part LU into which a signal requiring a high-speed communication treatment for driving the actuators AK is inputted and outputted is made to communicate with a central control part CU by a high-speed communication line T1. On the other hand, a terminal control part MU into which a signal not requiring the high- speed communication treatment is inputted and outputted is made to communicate with the central control part CU by a low-speed communication line T2.

Abstract: PROBLEM TO BE SOLVED: To avoid a hunting condition taking place more frequently, in which engine load goes out of a proper loading range so as to go to a high loading side, by correcting a set upper limit for vehicle speeds to the side of lower vehicle speeds in response to an increment in engine load when a vehicle is run while works are actually carried out even if an upper limit for vehicle speeds is set high by operational errors and the like. SOLUTION: Based on detected data from stored engine load, when it is judged that a condition, in which engine load goes out of a range of its proper values so as to go to the side of high engine load, is diverted from a set judging condition, an upper limit for vehicle speeds set by an upper vehicle speed limit setting means 21, is corrected to the side of lower vehicle speeds, and the operation of an actuator 13 actuating a transmission 10 for vehicle running, is thereby controlled so that engine load is kept in a proper range of it in such a way that detected vehicle speeds do not exceed an upper limit value having been corrected for vehicle speeds.
