US 12,565,073 B2 · Electronic suspension control apparatus

Abstract

An electronic suspension control apparatus of the invention is an apparatus that controls an electronic suspension having an electric motor, and under a predetermined operation condition, gradually decreases a thrust force command for the electronic suspension and performs short circuit control on the electric motor once the thrust force command falls to or below a predetermined value. The operation condition is either detection of a command giving a prior notice of stopping power supply to the electronic suspension, a short circuit command as a measure against a collision, detection of a predetermined decelerating vehicle speed, or detection, by a preview sensor, of a change in a road surface which is equal to or above a predetermined value.

An electronic suspension control apparatus that controls an electronic suspension having an electric motor, wherein

in response to a short circuit command as a measure against a collision, the short circuit command being given as a prior notice of a short circuit control before stopping power supply to the electronic suspension, the electronic suspension control apparatus
decreases a thrust force of the electronic suspension,
performs short circuit control on the electric motor once the thrust force falls to or below a predetermined value, and
stops power supply of high voltage to the electronic suspension after performing the short circuit control
wherein the electronic suspension control apparatus decreases the thrust force of the electronic suspension during a time from the prior notice of the short circuit control to the stop of the power supply.
