  • Patent number: 11505174
    Abstract: The present invention realizes a vehicle control device that, even when power characteristics of a power generation device and a power transmission device changes, senses degradation of vehicle components, corrects a drive instruction to the power transmission device, and is thereby capable of stabilizing vehicle behavior over a long term. The present invention, in a predetermined vehicle environment state, measures fluctuation in drive power and acceleration in a transient region by using vehicle behavior sensors 4, performs comparison with a reference fluctuation, and thereby senses degradation of vehicle components. The drive instruction to the transmission 16-side is corrected in accordance with the degradation of vehicle components that is sensed.

  • Patent number: 11486476
    Abstract: An extension/contraction mechanism in which an extension/contraction part is able to turn is provided. An extension/contraction mechanism according to one aspect of the present disclosure includes a first drive source connected to a sending/pulling part so as to be able to transmit a drive force, and a second drive source connected to the sending/pulling part and a turning part that rotatably supports the sending/pulling part so as to be able to transmit a drive force via a gear group. When a rotational speed transmitted to the sending/pulling part to rotate the sending/pulling part by the first drive source is equal to a rotational speed transmitted to the sending/pulling part to rotate the sending/pulling part by the second drive source, an extension/contraction part turns via the turning part. When the above rotational speeds are different from each other, the extension/contraction part is extended or contracted.

  • Patent number: 11472286
    Abstract: A vehicle includes a front-wheel motor, a rear-wheel motor, a temperature detector, and a distribution ratio controller. The front-wheel motor drives a front wheel. The rear-wheel motor drives a rear wheel. The temperature detector detects a temperature of the front-wheel motor and a temperature of the rear-wheel motor. If one of the temperature of the front-wheel motor and the temperature of the rear-wheel motor exceeds a second temperature, the distribution ratio controller decreases a torque of one of the front-wheel motor and the rear-wheel motor the temperature of which is higher than the other and increase a torque of the other. The second temperature is a value set lower than a first temperature that is a threshold used for determination as to whether output of the front-wheel motor or output of the rear-wheel motor is to be restricted.
