  • Patent number: 12280763
    Abstract: A power generation system includes an internal combustion engine, an electrical generator, and a power transmission mechanism. A method for controlling the system includes executing rotation speed control of driving the electrical generator by using electric power supplied from a battery, and matching a rotation speed of the electrical generator with a target rotation speed at the time of starting the power generation system. Output possible electric power of the battery and rotation speed of the electrical generator are acquired. A filtering process of reducing a component of a resonance frequency band of a spring-mass system including the engine, generator, and power transmission mechanism is executed on the rotation speed of the electrical generator. An upper limit torque of the electrical generator is calculated based on the filtered rotation speed and the output possible electric power. The rotation speed control is executed under a limitation of the upper limit torque.

  • Patent number: 12275399
    Abstract: A driving control device executes driving assistance control for a subject vehicle using a processor having a first controller and a second controller. The first controller executes lane keeping control while the second controller executes deviation preventing control. The processor determines whether or not the second controller starts the deviation preventing control during execution of the lane keeping control with the first controller. Upon a determination that the second controller starts the deviation preventing control during execution of the lane keeping control, the processor concludes the lane keeping control under execution, starts deceleration control for the subject vehicle, continues the deviation preventing control until the subject vehicle stops, and concludes the deviation preventing control under execution when the subject vehicle stops by the deceleration control.
