Definitions

  • the present invention relates to a method for operating a hydraulic brake system with integrated parking brake function for motor vehicles with two vehicle axles, which essentially consists of a pedal-operated pressure transmitter, at least one hydraulic pump, an operating element connected to an electronic control and regulating unit, and with inlet and outlet valves provided wheel brakes, the wheel brakes assigned to the second vehicle axle having means for performing a parking brake operation.
  • Such a hydraulic vehicle brake with a parking brake device is known from US Pat. No. 4,215,767.

  • the disturbing noise caused by the hydraulic pump when building up pressure is, however, to be regarded as less advantageous.
  • this object is achieved in that the hydraulic pump is controlled in such a way that the pressure required to initiate and / or terminate a parking brake operation is built up with a minimally possible pressure build-up gradient. This measure creates a low-noise pressure build-up.
  • a particularly advantageous development provides that the activation mode of the hydraulic pump is determined by the vehicle driver.
  • the hydraulic pump When the control element is briefly actuated by the vehicle driver, the hydraulic pump is actuated in such a way that the pressure required to carry out a parking brake operation builds up more slowly in the wheel brakes assigned to the second axis than when the control element is actuated over a longer period of time.
  • the pressure applied to the wheel brakes during a service braking phase is used to initiate a parking brake operation.
  • Fig.l is a schematic diagram of a hydraulic brake system on which the inventive method can be carried out and
  • FIG. 2 shows an axial sectional view of a hydraulic wheel brake for motor vehicles, which is used in the brake system shown in FIG. 1 on a vehicle axle.
  • the circuit diagram of a brake system for motor vehicles shown schematically in FIG. 1, has wheel brakes 3 on a first axle, the front axle, which, in contrast to other wheel brakes 2 on a second axle, the rear axle, have no locking device for carrying out a parking brake operation ,
  • the wheel brakes 2 with locking device are described in more detail below with reference to FIG. 2.
  • the wheel brakes 2, 3 are pressurized via inlet valves 13, 17 by a pedal-operated pressure transmitter 31, which is shown in FIG. 1 as a vacuum brake booster with a downstream master cylinder.
  • the pressure reduction in the wheel brakes 2, 3 takes place via outlet valves 14, 18, whereby the brake fluid in low pressure accumulator 32, 33 is required.
  • the brake system has an electronic control and regulating unit 9, and for the wheel brakes 2, 3 on both vehicle axles a hydraulic pump 4, 40, which together for the implementation of anti-lock controls (ABS) and for controls in the electronic stability program (ESP) are necessary.
  • ABS anti-lock controls
  • ESP electronic stability program
  • the hydraulic wheel brake 2 shown in FIG. 2 for motor vehicles has a brake housing 1 which engages around the outer edge of a brake disk 26 and two brake pads 24, 25.
  • the brake housing 1 has a brake cylinder 5 which receives a brake piston 6 axially displaceably.
  • brake fluid can be supplied by means of a hydraulic connection 8, so that a brake pressure builds up, which axially displaces the brake piston 6 towards the brake disk 26.
  • the brake lining 24 facing the brake piston 6 is printed against the brake disk 26, the brake housing 1 shifting in the opposite direction as a reaction and thereby also pressing the other brake lining 25 against the brake disk 26.
  • the wheel brake 2 shown in the drawing has a working memory 10 on the side of the brake housing 1 facing away from the brake piston 6.
  • the working memory 10 essentially consists of a storage piston 94 delimiting the operating pressure chamber 7 and a spring element 90 and ensures that the application force acting on the brake pads 24, 25 during a parking brake operation is almost independent of thermally induced changes in the area of the brake housing 1.
  • means for locking the brake piston 6 required, which are formed from a locking nut designed as a threaded nut-spindle arrangement and a first friction surface 98 on the storage piston 94.
  • the threaded nut-spindle arrangement the threaded nut 15 of which is formed in one piece with the brake piston 6, has a spindle 16 coupled to the threaded nut 15 by means of a non-self-locking thread.
  • the spindle 16 has a second friction surface 97 which cooperates with the first friction surface 98 just mentioned on the storage piston 94 when the brake piston 6 is locked.
  • a locking unit which is arranged outside the working memory 10 and is formed by two electromagnetic actuators designed as electromagnets 91, the armatures 92 of which are firmly connected to a locking element 93 designed as a slide.
  • the accumulator piston 94 is blocked by the slide 93 by preventing a translatory movement of a force-transmitting part 96, which is firmly connected to the accumulator piston 94, in the direction of the brake piston 6.
  • the force-transmitting part 96 is designed in such a way that it has two projections which are received by cutouts formed in the slide 93.
  • the force-transmitting part 96 is prevented from moving in the direction of the brake piston 6 by the projections being supported on the slide 93. If the slide 93 is moved by the electromagnets 91 in such a way that the projections of the force-transmitting part 96 are aligned with the cutouts on the slide 93, the force-transmitting part 96 or the storage piston 94 can move in the direction of the brake piston 6.
  • a hydraulic pressure is built up in the operating pressure chamber 7, which causes both a displacement of the brake piston 6 in the drawing to the left and a displacement of the storage piston 94 against the force of the spring element 90 in the drawing to the right.
  • the slide 93 can be actuated and can release the force-transmitting part 96.
  • a translatory movement of the storage piston 94 in the direction of the brake piston 6 takes place through the hydraulically prestressed spring element 90 until the friction surfaces 97, 98 engage, with which the brake piston 6 engages in one locked state.
  • the spindle 16 lifts off the central bearing 21 and the spring element 90 acts by means of the closed force flow from the storage piston 94 via the threaded nut-spindle arrangement on the brake piston 6 and applies the application force required to carry out the parking brake operation.
  • a hydraulic pressure is again built up in the operating pressure chamber 7 by the already mentioned hydraulic pump 4 and the accumulator piston 94 is shifted to the right in FIG. 2, the spring element 90 being hydraulically preloaded. Since the effective diameter of the accumulator piston 94 is selected to be larger than the effective diameter of the brake piston 6, the activation pressure for carrying out a parking brake operation is reduced.
  • the accumulator piston 94 is then blocked again by the slide 93 by means of the force-transmitting part 96.
  • the method according to the invention described below with reference to FIG. 1 provides that the hydraulic pump 4 is controlled in such a way that the pressure required to initiate and end a parking brake operation is built up with little noise.
  • This will be the necessary pressure built up by the hydraulic pump 4 with a minimum possible pressure build-up gradient predetermined by the construction property of the hydraulic pump 4.
  • the pressure build-up gradient means the time gradient of the delivery rate of the hydraulic pump 4. If this pressure build-up gradient is chosen to be sufficiently small, the noise generated by the hydraulic pump 4 is no longer perceptible to the driver in the interior of his motor vehicle.
  • the pressure in the wheel brakes 2 assigned to the rear axle is at the same time with the outlet valves closed 14 initially built up with a maximum possible pressure build-up gradient predetermined by the construction properties of the hydraulic pump 4. This continues until the brake pistons 6 of the wheel brakes 2 described with reference to FIG. 2 exert a sufficiently large application force for the safe standstill of the motor vehicle.
  • the pressure required for a sufficiently large application force is either determined with the aid of an acceleration sensor (not shown in FIG. 1) or, if no acceleration sensor is provided, by a sufficiently large pressure value.
  • the hydraulic pump 4 then builds up the pressure additionally required by means of the minimal pressure gradient just mentioned until the storage piston 94 described with the aid of FIG. 2 has been displaced sufficiently and the slide 93 can release the force-transmitting part 96 and thus the storage piston 94 ,
  • the inlet valves 13 and opening the outlet valves 14 By closing the inlet valves 13 and opening the outlet valves 14, the already described friction surfaces 97, 98 are brought into engagement with one another and the brake pistons 6 of the wheel brakes 2 of the rear axle se are locked by the action of the spring assembly 90 in a closed state, as already described with reference to FIG. 2.
  • the method according to the invention also provides that the control mode of the hydraulic pump 4 is determined by the vehicle driver. With a brief actuation of the control element 12 by the vehicle driver, the hydraulic pump 4 is actuated in such a way that the pressure required to initiate and terminate a parking brake operation is built up slowly, that is to say with a small pressure build-up gradient. The pressure build-up can be stopped by a further actuation of the control element 12. As already mentioned, the noise generated by the hydraulic pump 4 is imperceptible to the vehicle driver due to the slow pressure build-up. If the vehicle driver desires a rapid build-up of pressure to initiate or terminate a parking brake operation, then he must actuate the operating element 12 for longer, that is to say preferably longer than 3 seconds.
  • the necessary pressure is then built up with a maximum possible pressure build-up gradient predetermined by the construction properties of the hydraulic pump 4.
  • An alternative of the method according to the invention provides that the pressure build-up gradient is linearly linked to the actuation time of the operating element 12. This measure enables the vehicle driver to handle the speed of the pressure build-up independently.
  • the pressure applied to the wheel brakes 2, 3 of the rear and front axles during service braking is used to initiate a parking brake operation.
  • the initial situation is that the vehicle driver uses the service brake to stop his vehicle brings.
  • the driver of the vehicle actuates the brake pedal 11, after which pressure is built up in the wheel brakes 2, 3.
  • the inlet valves 17 of the wheel brakes assigned to the front axle are closed and the pressure applied during the service braking is locked in the wheel brakes 3 of the front axle after the vehicle driver has actuated the control element 12.
  • the hydraulic pump 4 then slowly builds up in the wheel brakes 2 of the rear axle until the accumulator piston 94 already described with reference to FIG. 2 or the force-transmitting part 96 in FIG. 2 are shifted to the right.
  • the slide 93 is then brought out of its position blocking the accumulator piston 94. If the inlet valves 13 of the wheel brakes 2 are subsequently closed and the outlet valves 14 are opened, the accumulator piston 94 moves to the left in FIG. 2, after which the friction surfaces 97, 98 are brought into engagement with one another.
  • the action of the spring element 90 already described tensions the brake piston 6 and thus the two brake linings 24, 25 against the brake disk 26.
  • the means for carrying out a parking brake operation are thus activated.
  • the pressure applied in the wheel brakes 2, 3 during a service braking phase is used by the method just described to initiate a parking brake operation.

Abstract

L'invention concerne un procédé pour faire fonctionner un système de freinage hydraulique à fonction de freinage de stationnement intégrée sur des véhicules à deux essieux. Ce système de freinage comprend essentiellement un régulateur de pression (31) actionné par pédale, au moins une pompe hydraulique (4), un élément de commande (12) relié à une unité électronique de commande et de régulation (9), des feins sur roues (2) équipés de soupapes d'entrée et de sortie (13,14), les freins sur roues (2) associés au second essieu étant dotés de moyens pour effectuer un freinage de stationnement. L'invention vise à réduire l'émission sonore développée par la pompe hydraulique (4) lors du début et de la fin d'un processus de freinage de stationnement. A cet effet, le procédé selon l'invention permet d'amorcer la pompe hydraulique (4) de telle sorte que la pression nécessaire à l'amorçage et/ou à la fin du processus de freinage de stationnement a un gradient de montée en pression plus faible relativement au gradient de montée en pression maximal possible, lequel est déterminé par la conception de la pompe hydraulique (4).
