Title:
ELECTRONIC CONTROL UNIT FOR ELECTRIC POWER STEERING
Document Type and Number:
WIPO Patent Application WO/2019/189645
Kind Code:
A1
Abstract:
[Problem] To increase the efficiency of heat dissipation in an electronic control unit of a power steering device. [Solution] An electronic control unit 20 for electric power steering is constituted from a single circuit board 22 that receives power supplied from the outside, the electronic control unit 20 being formed integrally with an electric motor 15, the heat generated from the electric power steering power source circuit components disposed on one surface side 23 of the circuit board 22 being dissipated by a conductor pattern (power source pattern PW1-PW3, GND pattern G1-G4) formed in a heat dissipation area 27 on the other surface side 25 of the circuit board 22.
