Abstract
Hydraulic motor vehicle braking system with wheel slip controller, comprising a brake pressure applicator (,), which consists of a pedal-activated vacuum brake booster (,) and a main brake cylinder (,) and is connected via a brake line (,) to at least one pair of wheel brakes (,), and a pump (,) connected to the brake line (,) for conveying pressure agent from the brake pressure applicator (,) in the direction of the wheel brakes (,) during wheel slip control, and at least one pressure modulation valve (,′) installed downstream in the brake line (,) to vary the brake pressure in the wheel brakes (,) during the wheel slip control process. Maximum vacuum brake force amplification is limited to a mean wheel braking pressure that represents normal braking without wheel slippage; when this representative mean value is exceeded the vacuum brake force amplification is supplemented by hydraulic amplification of wheel braking pressure as a result of activation of the pump (,), which is configured to a level of pressure that is proportionate to pedal force.
