Patent number: 10226978Abstract: A vehicle height adjustment device includes a changer, a detector, a vehicle height controller, and a malfunction detector. The changer is configured to change a relative position of a body of a vehicle relative to an axle of a wheel of the vehicle. The detector is configured to detect the relative position of the body of the vehicle relative to the axle of the wheel of the vehicle. The vehicle height controller is configured to control the changer based on a detection value detected by the detector to change the relative position to control a vehicle height, which is a height of the body. When the detection value detected by the detector changes by a predetermined amount or more in a predetermined period of time, the malfunction detector is configured to determine that there is a possibility of a malfunction occurring in the detector.Type: GrantFiled: March 24, 2017Date of Patent: March 12, 2019Assignee: SHOWA CORPORATIONInventors: Takahiro Kasuga, Takahiro Koresawa, Masayoshi Ikeda

Patent number: 10214070Abstract: A vehicle height adjustment device includes a changer, a vehicle height controller, and a malfunction detector. The changer is configured to change a relative position of a body of a vehicle relative to an axle of a wheel of the vehicle. The vehicle height controller is configured to change the relative position based on a detection value detected by a detector configured to detect the relative position so as to control a vehicle height, which is a height of the body. The malfunction detector is configured to detect a malfunction in at least one of the changer and the detector, the malfunction causing the vehicle height controller to continue to control the vehicle height to increase.Type: GrantFiled: March 24, 2017Date of Patent: February 26, 2019Assignee: SHOWA CORPORATIONInventors: Takahiro Kasuga, Takahiro Koresawa, Masayoshi Ikeda

Patent number: 10150531Abstract: A vehicle height adjustment device includes a changer and a controller. The changer is configured to change a relative position of a body of a vehicle relative to an axle of a wheel of the vehicle. The controller is configured to control the changer to make the relative position a target value so as to control a vehicle height of the body of the vehicle. The controller is configured to control the changer to maintain the relative position irrespective of the target value when a decreasing malfunction occurs causing the vehicle height to decrease.Type: GrantFiled: March 18, 2016Date of Patent: December 11, 2018Assignee: SHOWA CORPORATIONInventors: Takahiro Kasuga, Takahiro Koresawa
