Abstract
Disclosed are implementations of devices, systems, and methods related to a differential lock for independent traction wheels. In one implementation, a vehicle is provided. The vehicle may include first and second traction wheels, a speed input, a steering input, and a differential lock input. It may further include a vehicle control unit with memory and a processor, capable of commanding differential speeds based on speed and direction information, detecting differential lock requests, and commanding equal speeds during lock requests. The control unit may also detect requests to stop the differential lock and limit vehicle speed during lock periods. The vehicle may have a front, rear, and two sides, with traction wheels located opposite each other. The speed input may be user-operated, and the steering input may be a sensor providing information about a steered wheel. The differential lock input may be user operated.
