An improved hydraulically assisted braking and steering system of a vehicle having a hydraulic pump communicating with a hydraulic steering assist device and including a hydraulic brake assist device coupled in series between the pump and the steering assist device includes the provision of a flow splitter which operates to reduce the interdependence of the hydraulic brake and steering assist devices on the flow of fluid from the pump. The flow splitter communicates with the outlet of the pump and the inlet of the brake assist device and is operative when the back pressure from the brake assist device exceeds a predetermined control value to divert a fraction of the flow of fluid around the brake assist device directly to the steering assist device, thereby providing sufficient flow to operate both the brake and steering assist devices within their normal design limits, rather than having the brake assist device starve the steering assist device when under heavy load.
In a hydraulically assisted braking and steering system of a vehicle having a hydraulic pump communicating with a hydraulic steering assist device and including a hydraulic brake assist device coupled in series between the pump and the hydraulic steering assist device, and wherein the improvement comprises:
A method of controlling the flow of hydraulic fluid in a hydraulically assisted braking and steering system of a vehicle in which a hydraulic brake assist device is mounted in series between a hydraulic pump and a hydraulic steering assist device, said method comprising:
