Abstract: A speed maintenance instruction is output when a vehicle enters a next intersection and a predetermined condition is satisfied. It is determined whether a forward obstacle is disposed between the vehicle and the next intersection. A possibility of collision with the forward obstacle is determined if the forward obstacle is disposed between the vehicle and the next intersection and the vehicle maintains a current vehicle speed. When the possibility of collision is determined, the speed maintenance instruction is not output even if the predetermined condition is satisfied.

Abstract: A fuel cell electric automobile includes a fuel cell stack, a traction motor, a first control device for controlling output of the fuel cell stack, and a second control device for controlling electrical energy supplied to the traction motor. The first control device is provided vertically above the fuel cell stack, and the second control device is provided vertically below the fuel cell stack and on a lateral side of the traction motor.

Abstract: An electric automobile includes a motor room separated from the cabin and partitioned at the front of the vehicle body and housing a driving motor and a power control unit that drives/controls the driving motor, a pair of side frames extending in the front-back direction of the vehicle body at both sides of the vehicle body; and a unit support frame that encloses the power control unit on four sides and supports the power control unit. The unit frame is suspended from the pair of side frames and is fastened to the pair of side frames. The power control unit is supported by the unit support frame at at least the sides excluding that in the backwards direction of vehicle body of the four sides of the unit support frame.

Abstract: A power control unit for an electric vehicle is provided with: a first electric power converter used during traveling and cooled by a first surface of a cooling section; and a second electric power converter used during charging from an electric power source outside the vehicle and cooled by a second surface of the cooling section. The first electric power converter and the second electric power converter are arranged at positions superposed on each other when viewed in the direction from the first surface to the second surface.
