摘要： PROBLEM TO BE SOLVED: To provide a suspension apparatus that prevents an actuator 30 from abutting on a bound stopper 37 by contraction of gas in an air spring device 20 caused by a temperature change during stillness (ignition OFF) of a vehicle.SOLUTION: A vehicle height correction unit 62 is designed to prevent the actuator 30 from abutting on the bound stopper 37 during stillness of the vehicle (ignition OFF) by contraction of the actuator 30 caused by air contraction in the air spring device 20 associated with gas temperature decrease in the air spring device 20. The height correction unit changes capacity of gas sealed in the air spring device 20 on the basis of a difference ΔT between an internal temperature Tdetected by an internal temperature sensor 27 and an outside air temperature Tdetected by an external temperature sensor 70 so that a vehicle height changes to a direction opposite to a direction where the air contraction causes the vehicle height to change. As a result, the unit corrects a reference length of the actuator 30 to correct the vehicle height.

摘要： PROBLEM TO BE SOLVED: To improve durability of a brush part of a motor with a brush to be used for an electromagnetic shock absorber.
SOLUTION: A motor rotation angle θm is sampled by a prescribed period when a vehicle is stopped, and data showing an angle difference β between a reference motor rotation angle θm0 corresponding to a set vehicle height and the sampled motor rotation angle θm is stored (S20 to S25). When the number of data of the angle difference β reaches a prescribed number (S23:Yes), vehicle height change amount ΔH to average the frequency distribution of the angle difference β is calculated (S27). The vehicle height change amount ΔH is commanded to an air spring control part (S28). As a result, a target vehicle height is changed, and contact frequency with the brush in each commutator of the motor is averaged.
