Patent number: 10611204Abstract: Systems and methods for controlling one or more tractive assemblies of a vehicle responsive to a disabling event. A sensor is arranged to detect one or more conditions of a tractive element indicative of the functionality of the tractive element. The sensor generates data corresponding to the detected conditions. The tractive element is coupled to a frame of the vehicle and configured to support a portion of the weight of the vehicle. When the tractive element is determined to not be functioning properly, control signal(s) for an actuator are generated to control a distance between the tractive element and the frame. The control signal(s) cause the tractive element to be effectively raised from a support surface for the vehicle.Type: GrantFiled: April 19, 2018Date of Patent: April 7, 2020Assignee: Oshkosh Defense, LLCInventors: Ron Zhang, David Hansen, Deepak Shukla, Aaron Rositch
