METHOD FOR DETERMINING A FUNCTIONAL STATE OF A PRESSURE BUILD-UP VALVE, AND FUNCTION MONITORING DEVICE FOR A PRESSURE BUILD-UP VALVE OF A HYDRAULIC BRAKE BOOSTER |
摘要 |
A method for determining a functional state of a pressure build-up valve of a hydraulic brake booster of a brake system, having the following steps: comparing an activation intensity of an activation of a brake activating element of the brake system to a predefined minimum activation intensity; if the brake activation intensity is less than or equal to the minimum activation intensity, determining the functional state, taking into account a pressure change over time in at least a partial volume of the hydraulic brake booster; if the brake activation intensity is greater than the minimum activation intensity, determining the functional state, taking into account an operating mode which is predefined for a pressure reduction valve of the hydraulic brake booster. A function monitoring device for a pressure build-up valve of a hydraulic brake booster of a brake system is also described.
