Abstract
A damping coefficient control device for a shock absorber applied to a vehicle equipped with a wheel that is rotatably supported about a rotational axis and has a tire, and a drive system that drives the wheel via a transmission by an engine, in which the damping coefficient control device includes a variable damping coefficient shock absorber arranged between a wheel carrier and a vehicle body and an electronic control unit that controls the shock absorber, and the electronic control unit acquires information on an index indicating an equivalent moment of inertia of the drive system, and controls the damping coefficient of the shock absorber such that the smaller the equivalent moment of inertia indicated by the index, the larger the damping coefficient of the shock absorber.
Claims5
A damping coefficient control device for a shock absorber applied to a vehicle equipped with a wheel that is rotatably supported about a rotational axis by a wheel carrier and has a tire, a drive system that rotationally drives the wheel by a drive source via a transmission and a drive shaft, and a suspension arm that is arranged between the wheel carrier and a vehicle body, wherein
- the damping coefficient control device includes a variable damping coefficient shock absorber arranged between the wheel carrier and the vehicle body and an electronic control unit that controls the shock absorber, and the electronic control unit is configured to acquire information on an index indicating an equivalent moment of inertia of the drive system, and control a damping coefficient of the shock absorber such that the smaller the equivalent moment of inertia indicated by the index, the larger the damping coefficient of the shock absorber.
