<p>PROBLEM TO BE SOLVED: To automatically control a creep force apt to be dispersed according to each product by a simple constitution by effectively utilizing the results of an idle rotation speed control by an idle control means as a sensor indirectly expressing the creep force. SOLUTION: A creep force acting in stopping a brake is not used for traveling a vehicle but reactionally acts as a force lowering the rotation speed of an engine, so that it draws attention that the difference between a control value DFB for holding the engine rotation speed in this state to a target idle rotation speed and a control value stored and learned in an ordinary state without acting the creep force, namely, a learned value DLRN, indirectly indicates the creep force, thus attempting to set the creep force to constant. The memory of the engine controller memorizes a program shown in a flowchart, repeatedly executes it at fixed periods, and automatically controls a clutch mechanism so that the dispersion of the creep force according to each vehicle can be controlled within a tolerance.</p> |
