Proportional control hydraulic brakes - include manual override control to increase rear brake force

摘要

The normal braking control uses a double master brake cylinder with the rear brake pressure reduced w.r.t. increasing front brake pressure in order to maintain stability. A second master cylinder operated manually increases the rear brake force so that an experienced driver can obtain braking on good grip surfaces. The second master cylinder has its input linked to the rear brake output from the main cylinder, and in normal operation just transmits the braking force. Application of e.g. a hand brake lever, operates the second cylinder and enhances the rear brake force. The driver is also able to control rear skids for performance cornering.
