| 20090026835 | Hydraulic Braking Device - The first control is to displace the primary piston by the amount obtained by multiplying the input rod displacement quantity by a proportional gain. The second control is to propel the primary piston by a prescribed offset thereby executing the first control. The third control is to displace the primary piston by the amount obtained by multiplying the input rod displacement quantity by a proportional gain specifically at a pressure decrease request. The brake force control device properly selects a control method from the first to third control methods to control the primary piston based on the automatic braking release conditions and a driver's brake request when a driver executes a brake operation during the automatic braking. | 01-29-2009 |
