<p>PROBLEM TO BE SOLVED: To rapidly form the braking pressure by checking whether or not the time deduction of the magnitude to indicate the operation of a brake pedal exceeds the rise gradient threshold after the automatic braking effect is released. SOLUTION: When the accelerator pedal return velocity vg to be checked from the position of an accelerator pedal 1 by an accelerator control device 3 exceeds the threshold vgs, and replacement of a foot of a driver from the accelerator pedal 1 to the brake pedal 12 is confirmed, it is examined whether or not the time T1 exceeds the threshold T1S. When the accelerator pedal return velocity vg does not exceed the threshold vgs, or no foot is replaced, the checking of the accelerator pedal return velocity vg is returned again. When the time T1 exceeds the threshold T1S, the brake pressure is reduced and the process is started from the first stage. If the time T1 does not exceed the threshold T1S, and the operational speed vb of the brake pedal 12 exceeds the rise gradient threshold vbg, the automatic brake is continuously applied, and the maximum differential pressure is generated by a braking force reinforcing device.</p> |
