Title: Steering response type power boost
Inventor: ANDERSON LAWRENCE VERNON
IPC: B62D11/18
Filed: 2000-02-17
Abstract: PROBLEM TO BE SOLVED: To provide a crawler vehicle control system increasing the power output of an engine during turning operation, relative to engine power during linear operation. SOLUTION: A steering control system for a crawler vehicle includes an engine-driven variable displacement steering pump 40 for driving a hydraulic motor. The control system detects the position of a steering wheel, vehicle speed, engine speed and the forward/reverse direction of the vehicle and generates a control signal as a function of detected input to control the swash plate angle of the engine-driven variable displacement pump 40 for driving the steering motor 42 that drives a differential crawler drive mechanism, using this control signal. The control system further determines the ratio of motor speed to vehicle speed and generates a power boost signal in the case of this ratio exceeding the threshold. The power boost signal is transmitted to an engine control device, and the engine control device increses engine power output.  This changes a fuel delivery curve of an engine on the basis of output required for a steering system, to increase power usable for turning the vehicle.
