Abstract: In a motor-integrated electronic control device (2) of the present invention, a first connector (61) is provided at a first housing (81) on an opposite side to a motor (4), whereas a second connector (62) is provided at a second housing (82) on the motor (4) side, i.e. the first and second connectors (61, 62) are provided in different directions from each other, namely, that the first and second connectors (61, 62) are provided so as to face to mutually opposite directions. Therefore, a problem of intersection of electric signal of current flowing in electric circuit mounted on a first board (71) and electric signal of current flowing in electric circuit mounted on a second board (72) can be prevented. It is thus possible to suppress adverse effect on the electric circuit of the second board (72) by electric noise generated in the electric circuit of the first board (71).

Abstract: To start a vehicle, power is provided from the vehicle's electrical source to electrical load(s) in the vehicle. Heavy electrical load(s) can sag the vehicle's electrical system and make starting the vehicle difficult. The following embodiments can address this problem by providing an intelligent power distribution system that uses controllable switch(es) to selectively connect load(s) to the vehicle's electrical source in a controlled, progressive manner. Connecting load(s) in a controlled fashion can facilitate the starting of the vehicle by avoiding having electrical load(s) present at start-up.
