- Electromechanical brake pressure generator containing vehicle in particular a hybrid or electric vehicle.
- the braking force is applied to the piston / cylinder unit by means of a
- Electromechanical brake pressure generators are therefore particularly advantageous with regard to autonomous driving. State of the art
- electromechanical brake force generator when the brake pedal is pressed, the manually executed pedal travel is measured by an electronic pedal travel sensor and forwarded to an electronic control unit.
- the electronic control unit uses this to calculate corresponding control signals for an electric drive motor.
- the engine torque is converted into an assisting force for the driver via a multi-stage gear transmission.
- the force delivered by this booster is converted into hydraulic pressure for braking in a hydraulic piston / cylinder unit.
- the electromechanical brake pressure generator provides a brake feel that is comparable to conventional vacuum brake boosters. So the braking feeling can be controlled via the electronic
- a generic electromechanical brake pressure generator emerges from WO 2017/045804 A1.
- the brake pressure generator includes a
- the electric drive motor which is operatively connected via a multi-stage spur gear with a spindle drive unit such that a rotation of the electric drive motor causes a translational movement of a spindle of the spindle drive unit to actuate a master brake cylinder.
- the multi-stage spur gear generates in the radial direction to

- the invention is based on the object of an electromechanical
- the invention includes the technical teaching that the gear drive of an electromechanical braking force generator comprises a planetary gear unit driven by a motor pinion as a sun gear, the output-side ring gear of which drives the spindle drive unit in such a way that a motor shaft of the electric drive motor runs parallel and adjacent to a spindle drive shaft of the spindle drive unit.
- Planetary gear unit convertible high gear ratio enables a compact design. This is because the high transmission ratio that can be achieved via the planetary gear unit with the ring gear on the output side also enables the piston diameter of the hydraulic piston / cylinder unit to be reduced compared to conventional designs. This also reduces the drive forces acting on the components of the electromechanical braking force generator as a result of the power transmission, so that other components can also be made smaller.
- the spindle drive shaft runs not only parallel to the motor shaft of the electric drive motor, but also adjacent to it in the radial direction, which gives the structural unit greater compactness in the axial direction.
- the transmission concept according to the invention creates the prerequisite that the electromechanical brake pressure generator can preferably be implemented in a design in which the gear transmission is connected to a mechanical one

- all electrical and electronic components of the electromechanical brake force generator can be arranged in a structurally compact manner, so that, for example, the sensor for detecting the engine speed can also be arranged directly on the engine shaft and in the area of the electronic control unit, so that
- this comprises an intermediate step wheel, the larger gear of which meshes with the externally toothed ring gear of the planetary gear unit and whose pinion meshes with a spindle wheel of the spindle drive unit.
- the intermediate step wheel achieves a further increase in the transmission ratio for the transmission of the drive speed to slow speed and, on the other hand, construction-related radial distances between the electric drive motor and the adjacent spindle drive unit can be bridged.
- the electric drive motor of the electromechanical braking force generator is preferably accommodated in a pot-shaped motor housing. As a result, the motor housing can in addition to the protective function for the electrical

- the planet carrier can also be mounted in a floating manner relative to the motor housing.
- the device housing at least partially houses the spindle drive unit and the input rod, which is acted upon by a brake pedal.
- the gear drive is covered with a cover part that overlaps the motor housing and that also comes to rest on the device housing. Overall, this results in a multi-part housing structure via which the mechanical connection side in particular is easily accessible.
- the spindle drive unit consists essentially of a spindle nut and a spindle in thread engagement with it.

- an electronic control unit 7 for controlling the electric drive motor 2 in accordance with the required braking force assistance, which is determined in a manner known per se.
- a sensor 9 is also arranged in the area of the end of a motor shaft 8 opposite the gear transmission 4, which directly detects the motor speed of the electric drive motor 2 and forwards it over a short distance to the electronic control unit 7 for control purposes.
