摘要： The invention relates to a hydraulic vehicle brake system with a hydraulic pump and a high pressure hydraulic accumulator for external power braking and a conventional master cylinder that is used as a braking power set point adjuster for external power braking and is used to actuate the brake system by muscle power in the event of a failure of the external power brake system. The system connects an intake side of the hydraulic pump to a low pressure hydraulic accumulator into which brake fluid travels from the wheel brake cylinders when the wheel brake pressure decreases. The system has the advantage that no connections of the hydraulic pump to a reservoir of the master cylinder are necessary, which in the event of a leak, would jeopardize the function of both the external power service brake system and the muscle power auxiliary brake system.

摘要： The invention relates to a hydraulic motor vehicle power brake system having a hydraulic pump which is connected to a hydraulic reservoir as an external energy reservoir and is connected to wheel brake cylinders, wherein the wheel brake cylinders are preceded by inlet valves and are followed by outlet valves. To improve the adjustability of a desired brake pressure in the wheel brake cylinders and to cut costs, the inlet and outlet valves are identical as continuous pressure limiting solenoid valves or as continuous pressure differential solenoid valves.

摘要： A hydraulic vehicle brake system in which normal service brake operation can be carried out by using external hydraulic energy, and in the event of a lack of external hydraulic energy, auxiliary brake operation by muscle power is possible, with a hydraulic transmission that comes from a master cylinder that can be actuated by means of the brake pedal. The external hydraulic energy is stored, for example, in an accumulator with a gas buffer, which can lead to a gas content in the hydraulic fluid for the service brake operation. The system includes a dual-circuit master cylinder associated with those wheel brakes of a vehicle axle that make a higher contribution to the vehicle deceleration and at the same time, cylinder/piston devices are installed between these wheel brakes and their associated service brake valves for the purpose of preventing hydraulic fluid from getting into these wheel brakes from the external energy source. The advantage is that neither gas nor air is carried into the wheel brakes where it could lead to the formation of bubbles in the event of a pressure drop and would be disadvantageous for an auxiliary brake operation by the master cylinder. The cylinder/piston devices increase the operational safety of the vehicle brake system when braking by muscle power.

摘要： The invention relates to a hydraulic vehicle brake system (10), having a hydraulic pump (12) and a high-pressure hydraulic reservoir (22) for external-force braking, as well as a conventional master cylinder (28), which serves as a set-point brake force transducer for the external-force braking and serves the purpose of muscle-powered secondary braking if the external-force service brake system fails. To embody the vehicle brake system (19) with an active pedal travel simulator, the invention proposes connecting the master cylinder (28) to a low-pressure hydraulic reservoir (26) via a disconnecting valve (30) and to the high-pressure hydraulic reservoir (22) via a return valve (32).

摘要： An anti-locking control system is described in which the by electrical interference in the range of the mains frequency of conventional power supplies are detected and eliminated. To that end, in the range of critical speeds, a new reference vehicle speed is formed from the ascertained vehicle speed only if the time intervals between the arriving signal edges of the various rpm sensors are not in the range of the mains frequency.

摘要： The invention proceeds from a system for detecting a condition of the wheels of a motor vehicle. For this purpose, means are provided for generating rpm signals, which represent the rotational movements of the wheels, and evaluation means, by means of which a signal is outputted in dependence upon the generated signals, which signal represents the display-relevant condition. The essence of the invention is that the evaluation means are so configured that, first, and dependent upon the generated rpm signals, first difference values are formed for the rpm differences of at least two vehicle wheels on the two sides of the vehicle. Depending upon a first comparison of the formed difference values to each other and/or to pregivable first threshold values, the signal, which represents a display-relevant condition, is outputted. With the invention, one obtains a very simple and cost-effective wheel condition detection (emergency wheel detection, tire air loss detection) which operates correctly also when the vehicle drives through a curve.

摘要： Methods for recognizing a malfunction of a rotary speed sensor, for instance a wheel-speed sensor in an ABS system, are proposed; on the basis of the signals of the rotary speed sensor, wheel speeds are ascertained, and from them, filtered wheel speeds and filtered wheel speed changes are ascertained. By comparing filtered and unfiltered variables and by plausibility investigations, sensor errors and in particular absence of the sensor signal are detected.
