Abstract
The present invention discloses a method for use in automotive vehicles with an electronically controlled brake system (for example, ABS), wherein for controlling the braking pressure (re)increase during a control operation the rotational behavior of the individual wheels is measured and evaluated to determine braking pressure control signals, and wherein during a braking pressure control operation the braking pressure reduction in the previous cycle (,) is taken into account for the control of the braking pressure reincrease (,). According to the present invention, a braking pressure rise gradient (G) is calculated on the basis of the braking pressure increase in the preceding braking pressure increase phase (,), and the braking pressure increase or the variation of the braking pressure increase is calculated and predetermined on the basis of the rise gradient (G) and the calculated wheel cylinder pressure (P2) at the commencement of the current braking pressure increase phase (,) and on the basis of the current calculated locking pressure level (N3).
