System and Method For Vehicle Turning Radius Reduction

A vehicle control system for reducing turn radius of a vehicle may include a controller and a torque control module operably coupled to the controller and to front wheels of a front axle of the vehicle and rear wheels of a rear axle of the vehicle. The controller may also be operably coupled to components and/or sensors of the vehicle to receive information including vehicle wheel speed and steering wheel angle. The torque control module may be operable, responsive to control by the controller, to apply a negative torque to an inside rear wheel during a turn and apply a positive torque to the front axle during the turn to compensate for the negative torque applied to the inside rear wheel to reduce the turn radius based on the steering wheel angle and the vehicle speed.

MOTION AND TORQUE CONTROL ARCHITECTURE FOR MOBILE PLATFORM HAVING DISTRIBUTED TORQUE ACTUATORS

A motor vehicle includes first and second drive axles coupled to respective sets of road wheels, torque actuators inclusive of rotary electric machines configured to transmit respective output torques to the drive axles, and a main controller in communication with the torque actuators. The controller receives vehicle inputs indicative of a total longitudinal and lateral motion request. In response, the controller calculates a total longitudinal torque request and/or a total longitudinal speed request, a yaw rate request, and a lateral velocity request, then determines, using a cost optimization function, a torque vector for allocating the total longitudinal torque request and/or speed request, the yaw rate request, and the lateral velocity request to the drive axles within predetermined constraints. The controller also transmits a closed-loop control signal to each torque actuator or local controllers thereof to apply the torque vector via the drive axles.

PROCESS AND APPARATUS FOR RECOVERING CATALYST FROM A PRODUCT STREAM

A process for recovering catalyst from a fluidized catalytic reactor effluent is disclosed comprising reacting a reactant stream by contact with a stream of fluidized catalyst to provide a vaporous reactor effluent stream comprising catalyst and products. The vaporous reactor effluent stream is contacted with a liquid coolant stream to cool it and transfer the catalyst into the liquid coolant stream. A catalyst lean vaporous reactor effluent stream is separated from a catalyst rich liquid coolant stream. A return catalyst stream is separated from the catalyst rich liquid coolant stream to provide a catalyst lean liquid coolant stream, and the return catalyst stream is transported back to said reacting step.
