Definitions
- the invention relates to a method for controlling an electronically
- Electronically slip-controllable external power brake systems in motor vehicles are characterized, among other things, by the fact that at least under
- Muscle strength of the driver is generated.
- the driver only actuates one to specify a braking request
- Pressure generator of an actuator unit is controlled.
- the actuator unit then builds up a brake pressure corresponding to the actuation in at least one brake circuit of the brake system by external force.
- Vehicles are such external power brake systems for safety reasons with a second electronically controllable actuator unit
- Actuator unit redundant, second pressure generator unit.
- the pressure generator unit has hitherto been used to generate the brake pressure in the event that the first actuator unit fails. To ensure their function, the actuator units are separated from each other independent electronic control units and are also assigned to independent power supplies.
- a failure of the first actuator unit can be traced back to various causes, for example to an electrical or mechanical defect in a valve of a pressure modulation device of the first actuator unit and / or to an inadequate voltage supply, through which the assigned electronic control unit is unable to provide the necessary power for the motor to apply the generation of the desired brake pressure.
- the vehicle In the event of a failure of the first actuator unit, the vehicle will continue to be reliably braked with the second actuator unit, but if the failure occurs while the braking process is in progress, the driver can perceive this change in the actuator unit generating the brake pressure through a changed braking behavior of the external power brake system.
- Actuator unit is no longer available and the existing one
- Braking request can therefore only be derived indirectly from sensor signals of the second actuator unit.
- the valves of a pressure modulation device of the first will stop
- Actuator unit for a wheel-specific brake pressure control is no longer available, so that the usual slip or driving stability control functions of the external power brake system are only available to a limited extent.
- the invention proposes that functions of the power brake system associated with a high power requirement for this first actuator unit are transferred to the second actuator unit in advance of a potential failure of the first actuator unit.
- the build-up of brake pressure which requires a high level of electrical power, is therefore carried out by the pressure generator of the second actuator unit and thus the electrical load on the voltage supply of the first actuator unit is reduced.
- Pressure modulation unit still functional, so that the braking request is still detected immediately and also by the control unit of the second
- Actuator unit can be used as an input variable for generating brake pressure. As a result, the braking behavior of the external power brake system changes only slightly for a driver even in the event of a fault in the first actuator unit.
- Pressure modulation device of the first actuator unit due to its likewise low electrical power requirement despite the present
- a functional restriction of the voltage supply of the first actuator unit that precedes a failure is detected by a corresponding one Monitoring device controlling the motor of the first
- Controlled pressure generation unit of the second actuator unit for brake pressure setting and regulation in the brake circuit.
- Braking request detection device based on the first actuator unit.
- a device for monitoring the voltage supply of the first actuator unit can be integrated into the electronic control device of the first or the second actuator unit or can be connected as a separate structural unit to the voltage supply of an actuator unit.
- FIG. 1 shows the hydraulic circuit diagram of an electronically slip-controllable external power brake system on which the invention is based and known from the prior art, which is provided in particular for a piloted motor vehicle.
- FIG. 2 The method for controlling this external power brake system is shown in FIG. 2 with the aid of a flow chart.
- the electronically slip-controllable external power brake system 10 shown in FIG. 1 is made up of two actuator units 12a; 12b constructed. Both actuator units 12a; 12b each have their own and independent of the other actuator unit
- the first actuator unit 12a supplies a total of four wheel brakes 18 connected to it with pressure medium under braking pressure.
- two wheel brakes 18 are in each case in one of a total of two brake circuits 20a; 20b
- the brake pressure in these brake circuits 20 is under normal operating conditions of the power brake system 10 of a
- Pressure generating unit 22a of the first actuator unit 12a constructed. That pressure generating unit 22a comprises an electronically controllable motor 24a for actuating a plunger unit made up of a plunger cylinder 26 and a plunger piston 28 slidably accommodated therein two connected brake circuits 20a; 20b into it. In the brake circuits 20a; 20b thereupon builds up a brake pressure, the level of which depends on the amount of pressure medium volume displaced into it and thus ultimately on the actuation path covered by the plunger 28.
- the first actuator unit 12a also has a pressure modulation device. This consists of one pressure medium inlet valve 32 and one for each wheel brake 18 present
- Pressure medium outlet valve 34 These valves can be actuated electronically and, in the case of the pressure medium inlet valves 32, can be transferred from an open position to a blocking division or, in the case of the pressure medium outlet valves 34, from a blocking separation into an open position.
- Pressure medium outlet valves 34 are switching valves, while pressure medium inlet valves 32 are designed as proportional valves for better brake pressure regulation.
- each brake circuit 20a; 20b equipped with a so-called plunger control valve 36. Based on this plunger control valve 36 are the
- plunger control valves 36 are energized in the normal operating state of the external power brake system 10 and are therefore open. If necessary, they are closed for a limited period when the plunger 28 has reached its outer reversal point and the plunger working space 30 is to be filled with fresh pressure medium by reversing the direction of movement of the plunger 28 via pressure medium connections leading directly to a reservoir 38 for pressure medium.
- circuit isolating valves 40 are connected in parallel with the plunger control valves 36 and control two pressure medium connections via which the first actuator unit 12a is in contact with the second actuator unit 12b.
- the circuit separation valves 40 are designed as normally open switching valves, which under normal operating conditions by electronic control in a
- the first actuator unit 12a also has a
- Brake request detection device That consists of one
- Master brake cylinder 42 which can be actuated by an actuating element, exemplarily designed in the form of a brake pedal 44.
- An actuation travel of the brake pedal 44 is detected by a travel sensor 46 and fed to the first control device 16a assigned to the first actuator unit 12a.
- This control device 16a uses the path signal to determine a control signal for the motor 24a of the pressure generating unit 22a of the first actuator unit 12a.
- the master cylinder 42 has two cylinder chambers 48a; 48b, each of which is driven by an associated master brake cylinder piston 50a; 50b are limited. With an operation of the brake pedal 44 is at least one of the
- Master brake cylinder piston 50 is moved in a direction in which the volume of the associated cylinder chamber 48 is reduced.
- the two cylinder chambers 48 are connected to the reservoir 38 for hydraulic pressure medium.
- Two channels carrying pressure medium lead from the cylinder chambers 48 of the master brake cylinder 42 to the second actuator unit 12b, where they are in contact with the pressure side of the second pressure generating unit 22b.
- the first actuator unit 12a also includes a pedal travel simulator 52.
- This is a device made of a simulator piston, which counteracts the force of an elastic restoring element in one
- Simulator cylinder is displaceable.
- the simulator chamber enclosed in the simulator cylinder is connected via a controllable simulator control valve 54 to the first cylinder chamber 48a of the master brake cylinder 42 facing the brake pedal 44 in a pressure medium-conducting manner.
- the simulator control valve 54 When the simulator control valve 54 is open, the simulator chamber receives pressure medium displaced from this first cylinder chamber 48a of the actuated master brake cylinder 42. It thus enables an actuation travel of the brake pedal 44 without pressure medium being transported from the first actuator unit 12a to the second actuator unit 12b.
- the second actuator unit 12b is also divided into two separate second pressure medium circuits 58a; 58b split. These pressure medium circuits 58a; 58b are largely identical in structure and can be used from one to the other
- Pressure generating unit 22a of the first actuator unit 12a redundant second pressure generating unit 22b are acted upon with brake pressure.
- the second pressure generator unit 22b consists of a total of two pump elements 56 which can be driven jointly by the controllable second motor 24b. A suction side of each pump element 56 is directly connected to the
- Reservoir 38 contacted for pressure medium. Each is on the pressure side
- Each pressure medium circuit 58a; 58b of the second actuator unit 12b also has a controllable switchover valve 60. If necessary, these switching valves 60 provide one between the pressure side
- the open position, the brake pressure of the pressure medium circuits 58a, 58b can be regulated and thus the pressure with which the pressure generating unit 22b of the second actuator unit 12b acts on the wheel brakes 18.
- Switching valves 60 are normally open switching valves to which a bypass 64 controlled by a check valve 62 is connected in parallel.
- the check valve 62 prevents pressure medium when the
- Switching valve 60 from the pressure side of a pump element 56 to
- Master brake cylinder 42 flows off and at the same time enables the driver to operate the second actuator unit 12b when the second actuator unit 12b is active
- Brake master cylinder 42 can apply brake pressure to the wheel brakes 18.
- a pressure sensor 66 in the pressure medium connection of the second actuator unit 12b with the master brake cylinder 42 measures the brake pressure specified by the driver. So far, when the first actuator unit 12a has failed, this measured value represents the present braking request, which the electronic control unit 16b of the second actuator unit 12b as input variable
- Determination of the control signal for the motor 24b of the pump elements 56 of the second actuator unit 12b is used.
- the braking request detection device of the first actuator unit 12a is detected and fed to the electronic control device 16a of this first actuator unit 12a as an input variable.
- the control unit 16a determines a control signal for the motor 24a of the first from the detected pedal travel
- Pressure generating unit 22a which consequently builds up a brake pressure proportional to this pedal travel in the brake circuits 20a. Possibly. becomes this
- Pressure medium outlet valves 34 of the modulation device are adapted individually for each wheel to the slip conditions prevailing on the respectively assigned wheel.
- the second actuator unit 12b is passive during this normal braking operation and accordingly does not participate in the explained brake pressure build-up or in the brake pressure control.
- Actuator unit 12a assume their locking pitch and thus hydraulically decouple second actuator unit 12b from first actuator unit 12a.
- valves of the first actuator unit 12a assume the basic positions shown in the drawing when they fail. In this basic position, the plunger control valves 36, the simulator control valve 54 and the pressure medium outlet valves 34 are closed, while the
- Circular separation valves 40 and the pressure medium inlet valves 32 are open.
- the second actuator unit 12b is separate because of their
- Actuator unit 12b thus results in the connection between the pressure side of the pump elements 56 and the master brake cylinder 42 being interrupted, while a connection between the pressure side of the pump elements 56 and the brake circuits 20 of the first actuator unit 12a is established via the open circuit isolating valves 40.
- the braking request is derived in a conventional manner from the signal of the pressure sensor 66 of the second actuator unit 12b.
- the pressure sensor signal is converted by the electronic control unit 16b of the second actuator unit 12b into a control signal with which the motor 24b is controlled.
- the brake pressure generated by the pump elements 56 passes through the open circuit isolation valves 40 and the also open ones
- the detection of the braking request based on the signal from the pressure sensor 66 of the second actuator unit 12b is not fully satisfactory because the braking behavior of the external power brake system 10 changes noticeably for the driver as a result of the indirect detection of the braking request.
- Brake pressure generation by the first actuator unit 12a during an ongoing braking process is not only transferred to the second actuator unit 12b when the first actuator unit 12a has already failed, but rather in advance of an expected failure of the first actuator unit 12a, i.e. if functional restrictions or implausibilities in the voltage supply of the first actuator unit 12a have been determined using a method known from the prior art.
- a device 70 that monitors the voltage supply 14a of the first actuator unit 12a.
- a monitoring device 70 can for this purpose both in the control device 16a the first actuator unit 12a or in the control unit 16b of the second
- Actuator unit 12b be integrated.
- Braking request detection devices 42-46 are accordingly available input variables which directly represent the braking request and which can be used as input variables by the electronic control unit 16b of the second actuator unit 12b to determine a control signal for the motor 24b for driving the pump elements 56.
- the brake pressure generated by the second actuator unit 12b therefore continues to correlate very well with the driver's existing braking request and changes in the braking behavior of a
- Pressure medium outlet valves 34 of the pressure modulation device of the first actuator unit 12a also provide a controllability of the driving stability of the vehicle.
- a first step 80 of this method the voltage supply of the first actuator unit 12a is checked with the aid of a monitoring device 70.
- this monitoring device 70 sets functional restrictions or implausibilities in the function of the voltage supply of the first
- Actuator unit 12a which is a potential failure of this first
- Actuator unit 12a can precede electrical control of the motor 24a of the first actuator unit 12a by the assigned first electronic control unit 16a is prevented (item 82).
- the electronic control unit 16b of the second actuator unit 12b then moves the switching valve 60 into the blocking division and controls the motor 24b of the pressure generating unit 22b of the second actuator unit 12b to generate a brake pressure in the brake circuit 20 (item 86).
- the electronic control device 16b uses the signals 92 from the braking request detection device of the first actuator unit 12a. As a result, the brake pressure prevailing in a brake circuit 20 during a braking process is generated by the second actuator unit 12b and ideally the driver does not experience any changed braking behavior
- one of the electronic control units 16 can send an acoustic and / or an optical warning or information signal 94 to the driver, with which he can, for example, respond to the
