Brief description of the brake is actuated by an electric motor vehicle and system of braking, has electrical actuation

摘要

The speeds of the wheel are measured, the actuators of the wheel brake to continuous action applied to each wheel, a braking pressure independent, the sliding and the acceleration of the wheel are calculated for each wheel, the real instantaneous value of the braking pressure at the crossing of a threshold value of the sliding and / or acceleration of the wheel is placed in memory, the quotient is formed from the real value in memory and a pressure value characteristic of the vehicle for a coefficient of friction = 1 to the wheel in question and a first coefficient of friction, is estimated, an anti-lock control of the pressure of the brake is carried out with the aid of the estimated coefficient, the first coefficient is erased at the crossing of a second threshold value of the sliding and / or acceleration of the wheel towards the bottom and it is replaced by a coefficient considered each time a new, which can be increased up to the value corresponding to a track, dried and the braking pressure in the memory is used as a reference value of the anti-lock control.
