  • Patent number: 11654780
    Abstract: In one aspect of the present disclosure, a method is provided for operating a vehicle system comprising a motor, a battery, and a controller. The vehicle system is configured to provide at least one of regenerative braking wherein the motor operates to charge the battery and propulsion wherein the motor uses electrical power from the battery to propel the vehicle. The method includes, at the controller, determining an effective motor power at a motor speed and a motor torque. The effective motor power is determined based at least in part on a calculated motor power and an electrical power loss of the motor corresponding to the motor speed and the motor torque. The method further includes causing the motor to apply the motor torque to a wheel of the vehicle upon the effective motor power satisfying an operating condition of the vehicle system.

  • Patent number: 6257364
    Abstract: An electro-hydraulic power steering system having a motor, a pump, and a control module all formed as an integral unit. The motor is shaft coupled to the pump and the pump housing and the motor housing are sealingly attached to prevent any fluid leakage. The control module is sealingly attached to the pump housing to prevent any fluid leakage. The control module is in electrical communication with the motor in order to drive a motor shaft and operate the hydraulic pump. The entire unit is submersible and can operate when submersed.
