  • Patent number: 12330625
    Abstract: In a control method of a vehicle, an electric power consumption, which is an electric power consumed by the motoring, includes a friction electric power consumption, which is an electric power consumption of the motoring determined according to friction of the internal combustion engine, and an inertia electric power, which is an electric power consumed for an inertia torque for changing a rotation speed of the internal combustion engine.

  • Patent number: 12269455
    Abstract: A series hybrid vehicle control method charges a battery with electric power generated by an electric power generation motor driven by an internal combustion engine, and electric power regenerated by a drive motor. The control method starts generating the electric power by the engine if a requested output exceeds a power generation start threshold value, and stops generating electric power by the engine if the requested output falls below a power generation stop threshold value. A deceleration rate by regeneration of the drive motor is greater in a second advancement shift position than in a first advancement shift position. The power generation start threshold value and/or the power generation stop threshold value where the second advancement shift position has been selected is greater than the power generation start threshold value or the power generation stop threshold value where the first advancement shift position has been selected.

  • Patent number: 11971104
    Abstract: A grommet G according to the present invention is provided with, on the outer side of a second flexible portion 22, a padding portion 4. With this, of a pressing force F which acts from the cylindrical base part 1 side to the seal portion 3 side, a panel parallel component F1 parallel to a dash panel DP is hardly transmitted. On the other hand, a panel vertical component F2 vertical to the dash panel DP is easily transmitted. Consequently, the panel vertical component F2 becomes relatively large, and even if the seal portion 3 is brought into contact with the dash panel DP by acting the pressing force F from the oblique direction, the rolling-up caused by the occurrence of the inclination of the seal portion 3 can be suppressed.

  • Patent number: 11851045
    Abstract: A series hybrid vehicle control method for controlling a vehicle that has a battery, an electric power generating motor, a drive motor and an internal combustion engine. The battery charged with the electric power from the electric power generating motor that generates electric power by being driven by the internal combustion engine, and charged with the electric power regenerated by regenerative braking of the drive motor. The drive motor drives a drive wheel. The electric power consumption for motoring is greater in a B range than in a D range. The control method sets deceleration caused by regenerative braking of the drive motor to be greater in the B range than in the D range, and starts motoring of the internal combustion engine in the B range at a lower SOC of the battery than the SOC of the battery in the D range.
