Abstract
The present invention relates to an electronic control unit (ECU) structure of a brake system, and has an ECU board that is arranged, as an addition, in a symmetric or asymmetric structure in order to form redundancy in preparation for the breakdown of an ECU, and has sensors that are also arranged for implementation of the redundancy, and thus the brake system can be operated even if a part of the ECU breaks down.
Claims11
An electronic control unit (ECU) assembly structure of a brake system, comprising:
- a housing having spaces separated by a partition;
- a first control unit and a second control unit which are independently disposed in the spaces separated by the partition;
- a first microcontroller unit (MCU) and a second MCU respectively positioned on the first control unit and the second control unit;
- a cover configured to cover the spaces in which the first control unit and the second control unit are disposed;
- a bus bar disposed to pass through the partition to connect the first control unit and the second control unit;
- a motor;
- and
- a first motor position sensor and a second motor position sensor which are disposed within a radius of a magnet mounted to the motor and connected to the first control unit and the second control unit, respectively,
- wherein:
- the second control unit constitutes redundancy of the first control unit to perform the same function as the first control unit;
- and
- the motor, a coil, and a pedal sensor connected to the first control unit and the second control unit are connected to the first control unit and the second control unit in a symmetrical structure.
