Definitions
- the invention relates to a method for operating a hydraulic motor
- Brake system of a motor vehicle comprising at least one hydraulically actuated wheel brake, a brake pedal device with an actuated brake pedal for setting a desired braking torque and a pressure generator, which is electrically actuated to generate a hydraulic pressure in dependence on the desired braking torque, wherein an electrical operating current of the pressure generator in Normal operation is limited to a first predetermined limit.
- the invention relates to a device for carrying out the
- Vacuum brake booster dispensed and instead an electrically controllable pressure generator is used.
- This generates the hydraulic pressure without being mechanically coupled to the brake pedal. Rather, the operation of the brake pedal is detected and monitored by one or more sensors and the pressure generator in dependence on the Brake pedal actuation activated.
- the pressure generator is, for example, a pump, which is associated with an electric motor to set electro-hydraulically the pressure in the brake system. In this case, the pressure generator is controlled such that a required by the driver by pressing the brake pedal desired braking torque is set at one or more wheel brakes of the brake system to delay the motor vehicle.
- the electric motor is driven such that in the case of low speeds, the torque and thus the operating current are limited to a first limit.
- the inventive method with the features of claim 1 has the advantage that the brake pedal device on the type of operation of the
- the method according to the invention has the advantage that the driver is provided with the desired braking torque in a short time during highly dynamic braking processes, while nevertheless ensuring that overheating of the pressure generator, in particular its electric motor, is permanently prevented.
- Braking does not last long, but is characterized in particular by its temporal brevity, overheating of the electric motor due to the short-term increased load on the electric motor is almost impossible.
- Brake pedal operating speed exceeds a predetermined second limit.
- the operating speed of the brake pedal is expediently monitored and compared with the second limit value.
- Brake pedal actuation speed is in particular by means of a
- Displacement sensor determines which is assigned to the brake pedal.
- a highly dynamic actuation is detected when a detected brake pedal travel exceeds a predefinable third limit value.
- the brake pedal travel is compared here with a third limit value.
- the third limit value is selected to prevent brake pedal operations, which are performed at a high speed but require only a low braking torque, from being detected as high-dynamic brake pedal operations.
- the first limit value is predetermined as a function of an operating temperature of the pressure generator.
- the advantage is achieved that a dynamic control of the pressure generator takes place, which depends on the current operating temperature of the pressure generator.
- the current operating temperature is compared with a maximum allowable operating temperature to determine whether or not the temperature may continue to rise.
- the first limit value is varied, so that exceeding the limit temperature is reliably prevented. It is assumed that high-dynamic braking increases the operating temperature only briefly and thus negligibly. According to an advantageous development is also provided that the
- Limiting the operating current through the first limit only at speeds below a fourth limit occurs. This takes into account that, in particular at low rotational speeds, the torque for driving the pressure generator is high, so that in this case high operating currents occur which lead to heating of the pressure generator, in particular its electric motor. to lead.
- the pressure generator operates in a high speed range
- the first limit value as a function of a permissible operating temperature of the pressure generator at a
- the first limit value is specified in particular fixed and not dynamic and corresponds to the
- Brake pedal actuation generates a status message and to a
- Pressure generator activating control unit sends.
- the brake pedal device thus sends the information as to whether or not a high-dynamic brake pedal actuation has taken place, even to the control device, which then actuates the pressure generator in response to this information or suspends or adjusts the limit by the first limit value.
- the device according to the invention with the features of claim 8 is characterized by a control unit, which is specially adapted to, at
- the braking system according to the invention with the features of claim 9 is characterized by the device according to the invention. This results in the already mentioned advantages.
- Figure 1 shows a hydraulic brake system of a motor vehicle in a schematic representation
- Figure 2 is a flowchart for explaining an advantageous
- Figure 1 shows a simplified representation of a brake system 1 for a motor vehicle not shown here in detail.
- the brake system 1 has a plurality of wheel brakes 2, which by a driver of the motor vehicle by a
- Brake pedal device 3 can be actuated as service brakes.
- the wheel brakes 2 are denoted by LR, RF, LF and RR, which explains their position or assignment on the motor vehicle, where LR stands for the left rear, RF for the right front, LF for the left front and RR for the right rear.
- LR stands for the left rear
- RF for the right front
- LF for the left front
- RR for the right rear.
- the two brake circuits 4 and 5 are constructed identically, so that the structure of both brake circuits 4, 5 will be explained in more detail below with reference to the brake circuit 4.
- the brake circuit 4 is first with a master cylinder 6 of the
- Brake pedal device 3 is connected, wherein the master cylinder 6 is designed here as a double-piston or tandem cylinder, and wherein the brake pedal device 3 also actuated by the driver
- the brake circuit 4 has a switching valve 8, which follows the master cylinder 6.
- the switching valve 8 is designed to be normally open and allows a flow of the hydraulic medium of the brake circuit, so the brake fluid, in both directions.
- the switching valve 8 is further with the two wheel brakes 2 with the interposition of one
- Inlet valve 10 is connected, which is formed normally open in both directions.
- the wheel brakes 2 of the brake circuit 4 is also assigned in each case an exhaust valve 11, which is designed to be normally closed.
- the Exhaust valves 11 are connected on the outlet side with a hydraulic tank 9, which supplies the master cylinder 6 with hydraulic medium.
- the outlet valves 11 are also connected to a suction side of a pump 13 which is connected on the pressure side between the changeover valve 8 and the inlet valves 10 to the brake circuit 4.
- the pump 13 is presently designed as a piston pump and mechanically coupled to an electric motor 14, wherein the pump 13 and the electric motor 14 together form a pressure generator 15 of the brake system 1.
- the electric motor 14 is assigned to the pumps 13 of both brake circuits 3, 4 and 5.
- each brake circuit 4, 5 has its own electric motor 14.
- the master cylinder 6 is also a hydraulic
- Hydraulic pressure is automatically increased by the pressure generator 15 in the brake system 1, so that the driver with little effort a high
- FIG. 2 shows a simplified flowchart for explaining an advantageous method for operating the brake system.
- the method Upon actuation of the brake pedal 7 of the braking device 3, the method is started in the first step Sl.
- a subsequent query S2 it is checked whether the brake pedal operation is a high-dynamic brake pedal operation. For this purpose, the actuation speed and the actuation travel of the brake pedal 7 are detected and compared with a respective limit value.
- the detected brake pedal travel exceeds the assigned limit value and the actuation speed is higher than the corresponding limit value, it is recognized that a high-dynamic brake actuation occurs (j). However, if the actuation speed is less than the limit and / or the brake pedal is not allowed beyond the associated limit Pedal away, it is recognized that there is no high-dynamic brake pedal operation (s) and referenced to a step S3. In this step, the operating current for the pressure generator 15 is limited to the allowable first limit.
- Electric motor of the pressure generator 15 is prevented, it is provided that in normal operation, the operating current of the pressure generator is limited by a first limit. This will be explained in more detail with reference to the method shown in FIG.
- step S4 the pressure generator 15 is then activated in step S4 to generate the hydraulic pressure.
- the brake pedal actuation is a high-dynamic brake pedal actuation (j)
- step S4 the procedure advances from step S2 to step S4, so that the limitation of the operating current does not take place or is canceled.
- the pressure generator 15 can be supplied with an increased operating current in a highly dynamic braking process, so that it is a high even at low speeds
- Brake system 1 is built in a very short time. Due to the fact that the limitation is only canceled for high-dynamic braking operations, it is ensured in normal operation that the operating temperature is not exceeded. In a highly dynamic braking process, the thermal load depends on the amount and duration of the operating current. Because at a highly dynamic braking process, the thermal load depends on the amount and duration of the operating current. Because at a highly dynamic braking process, the thermal load depends on the amount and duration of the operating current. Because at a highly dynamic
- Torque increase depends on the dimensioning of the electric motor and the implemented current limits.
- FIG. 3 shows by way of example in a diagram the torque characteristic of the electric motor 14 of the pressure generator 15, as the pressure moment Md over the speed n, in normal operation (K1) and in the case of a highly dynamic one
- Characteristics Kl and K2 lie one above the other.
