OUTBOARD MOTOR STEERING SYSTEM

摘要

In an outboard motor steering system, the engine speed is detected as a val ue indicative of the speed of the boat and a current value for operating a steering hydraulic cylinder is determined to decrease with decreasing engine speed. T he current value can therefore be determined in accordance with the steering lo ad to reduce electric power consumption. Moreover, owing to the fact that the driv e current is determined as a function of steering load, it is possible to prevent the output of the cylinder from becoming excessive relative to the steering load , thereby ensuring that the steered angle tracks a desired steering angle with good accuracy.
