Abstract
Official abstract text for this publication.
An electric suspension apparatus includes an electric actuator mounted in a vehicle, the electric actuator being driven with a motor, a voltage determination unit determining whether an electromotive force generated by the motor is equal to or more than a predetermined voltage in a state where regenerative power is generated in the motor, and an instruction unit short-circuiting the motor in a case where the voltage determination unit determines that the electromotive force generated by the motor is equal to or more than the predetermined voltage.
First claim
Opening claim text (preview).
What is claimed is: 1. An electric suspension apparatus comprising: a processor; and an electric actuator mounted in a vehicle, wherein the electric actuator being driven with a motor, wherein the electric actuator includes a screw shaft and a nut screwed to the screw shaft, wherein in a case where a drive voltage of the motor is equal to or more than a predetermined voltage, the processor short-circuits the motor, and wherein in a case where a change amount of the drive voltage per unit time is equal to or more than a predetermined change amount, the processor short-circuits the motor. 2. The electric suspension apparatus according to claim 1 , wherein in a case of short-circuiting the motor, the processor stops supply of power to the motor. 3. An electric suspension apparatus comprising: a processor; and an electric actuator mounted in a vehicle, wherein the electric actuator being driven with a motor, wherein the electric actuator includes a screw shaft and a nut screwed to the screw shaft, wherein in a case where a drive voltage of the motor is equal to or more than a predetermined voltage, the processor short-circuits the motor, wherein the electric actuator is disposed in each of a plurality of wheels, and wherein in a case where the drive voltage is equal to or more than the predetermined voltage in association with stroke fluctuation of the electric actuator disposed in a front wheel, the processor holds the short circuit of the motor disposed in each of the plurality of wheels until stroke fluctuation of the electric actuator disposed in a rear wheel ends. 4. The electric suspension apparatus according to claim 3 , wherein in a case of short-circuiting the motor, the processor stops supply of power to the motor.
