Abstract
The present disclosure relates to an electrohydraulic brake module for a motor vehicle brake system, comprising a housing, a hydraulic module with a piston/cylinder arrangement for generating a hydraulic brake pressure, an electric motor for driving the piston/cylinder arrangement, and a transmission arrangement for mechanically transmitting a brake pedal deflection. Furthermore, the brake module comprises a sensor cluster. The brake module has a redundantly acting sensor system and mechanism.
Claims19
An electrohydraulic brake module for a motor vehicle brake system, comprising
- a housing,
- a hydraulic module with a piston/cylinder arrangement for generating a hydraulic brake pressure,
- an electric motor for driving the piston/cylinder arrangement,
- a transmission arrangement for mechanically transmitting a brake pedal deflection,
- a pedal travel transducer arrangement which is coupled to the transmission arrangement and is guided or mounted in the housing, with a first mechanism element and a second mechanism element,
- a printed circuit board which is connected to the housing, with a sensor cluster which has a pedal travel sensor arrangement,
- the pedal travel transducer arrangement having a first pedal travel transducer, the pedal travel sensor arrangement having a first pedal travel sensor, the first pedal travel transducer and the first pedal travel sensor together forming a first pedal travel detection unit which electronically detects the brake pedal deflection during operation,
- the pedal travel transducer arrangement having a second pedal travel transducer, the pedal travel sensor arrangement having a second pedal travel sensor, the second pedal travel transducer and the second pedal travel sensor together forming a second pedal travel detection unit which electronically detects the brake pedal deflection during operation in a redundant manner with respect to the first pedal travel detection unit,
- the first mechanism element establishing a force flow between the transmission arrangement and the housing in the case of a brake pedal actuation, and the second mechanism element establishing a force flow between the transmission arrangement and the housing in a redundant manner with respect to the first mechanism element in the case of a brake pedal actuation.
