The invention belongs to the technical field of automobile steering control systems, and discloses an electric power assisting steering system for an automobile. The electric power assisting steeringsystem for the automobile comprises an outer shell and a motor, and a controller assembly is arranged in the outer shell in an accommodating mode; the motor is arranged on the outer shell in an integration mode; the outer shell comprises a first shell body, a second shell body and a third shell body, and the motor is connected to the first shell body; one end of the second shell body is connectedwith the first shell body, the controller assembly is installed on the second shell body, and the controller assembly is electrically connected with the motor; and the third shell body is connected with the other end of the second shell body and an inserting opening connected with an external element is formed in the third shell body. According to the electric power assisting steering system for the automobile, the first shell body, the second shell body and the third shell body are adopted to enable a regulating circuit board, a drive circuit board and a control circuit board to be arranged in a stack mode, on the one hand, the steering system is compact in structure, on the other hand, strong and weak currents separate mutually, and electromagnetic coupling and interference are avoided.
Description
technical field [0001] The invention relates to the technical field of automobile steering control systems, in particular to an electric power steering system for automobiles. Background technique [0002] Automobile Electric Power Steering System (EPS) is composed of controller and steering gear assembly. When the driver needs to turn, the sensor part on the steering gear assembly collects the steering wheel angle signal, torque signal, vehicle speed signal and other related information and transmits it to the controller. After internal processing and calculation, the controller outputs instructions and controls the output power of the drive motor. The power is output to the wheels through the mechanical transmission system to complete the steering action. [0003] With the increasingly high requirements for light weight and intensification of automobiles, the available space on automobiles has become less and less, but the increasingly high requirements for intelligent el...
