Abstract

An embodiment of the invention provides a redundant electric power steering device. The redundant electric power steering device includes a first circuit board and a second circuit board configured to control a motor; the first circuit board and the second circuit board are arranged in a stacked mode in the direction parallel to the end surface of a motor shell; a plurality of control units are arranged on the first circuit board; the second circuit board comprises a plurality of redundant parts; the plurality of redundant parts are positioned on the same plane; and each redundant part is connected with the first circuit board in a bending manner. According to the redundant electric power steering device, the occupied space of a circuit board and part composition in the redundant electric power steering device are reduced, the arrangement efficiency in packaging is improved, the packaging size is reduced, the space utilization rate is improved, and the limitation of the installation space in a vehicle is overcome.

Description

technical field [0001] The invention relates to the field of control, in particular to a redundant electric power steering device. Background technique [0002] Electric power steering system (Electric Power Steering, EPS) is based on the traditional mechanical steering mechanism, adding signal sensing device, electronic control device and steering assist mechanism, which uses the power generated by the electric motor to help the driver to steer. When not turning, the motor does not work; when turning, the steering wheel torque and rotation direction signal detected by the torque sensor is sent to the control unit, and the control unit sends the motor a When a command is issued, the motor outputs a torque of corresponding magnitude and direction to generate power assistance. [0003] Currently, some systems including the EPS system employ packaging technology that integrates an Electronic Control Unit (ECU) that controls the motor's rotational speed and rotational torque wi...
