Abstract: A drive force control system that ensures a running stability and a driving performance of a vehicle even in the event of failure of one of motors. The drive force control system determines that one of the right motor and the left motor cannot generate a required torque due to failure. In the event of failure of any one of the motors, the drive force control system generates a torque by the other motor working properly, and controls the torque transmitting capacity of the clutch in such a manner as to deliver the output torque of the motor working properly to the wheel coupled to the faulty motor.

Abstract: A vehicle driving system includes: a left wheel driving system having a first motor and a first speed changer; a right wheel driving system having a second motor and a second speed changer; a motor controller which controls the first motor and the second motor, a rotation restricting unit which can be shifted between a released state and an applied state; and a rotation restricting unit controller which controls the rotation restricting unit. When the rotation restricting unit controller shifts the rotation restricting unit from the applied state to the released state, the motor controller controls the first motor and the second motor so that a torque sum of the first motor and the second motor approaches zero while maintaining a torque difference between the first motor and the second motor.

Abstract: Control for an auto-balancing transportation device and the transportation devices having such controls. The controls monitoring system power and power use and generating a corrective response when the difference between system (or device or available) power and power use is below a given threshold. Power use may be calculated using a velocity parameter which provides a measure that more accurately reflects the environment conditions in which the device is being use, and provides benefits over a one-speed speed limit. Various corrective responses including pitch back and alarms, including those to a user-borne device are disclosed.
