Abstract: An improved estimator is provided for road/tire friction. The friction estimator provides near-real-time friction estimation, even while the car is accelerating, braking or turning. It is desirable to have an instantaneous and continuous estimate of the road/tire friction, but an estimate that occurs over several wheel rotations is more realistic. The estimate relies on easily measured signals such as yaw rate, lateral acceleration, wheel speed, etc. The estimate can be used to give the driver or a closed-loop controller an advanced warning when the tire force limit is being approached.

Abstract: A non-active regenerative system (20) which regenerates energy by taking energy from relative motion of members (22) and (24) and using it later to accomplish overall improved performance and eliminates the need for an active source to provide assisting forces. The non-active regenerative system (20) includes an energy transformer element (26) interconnecting a first member (22) and second member (24) which converts relative motion to an energy in storable form, and an energy management element (30) which channels the flow of energy to and from an energy storage element (32) to produce assisting forces. The energy management element (30)is commanded by a controller (36) which is responsive sensors (34a, 34b, 34c, and 34d) which provide signals indicative of the system condition. Power is supplied to the energy management (30), sensors (34a, 34b, 34c, and 34d), and controller (36), only if required, by power source (40). However, no active power source is needed to drive the transformer element (26). Embodiments of the non-active regenerative system (20) include non-active actuators and controllable mounts. Further, pulse width modulation of the energy management element (30) may be provided to reduce the system losses associated with tracking a desired force as dictated by a control algorithm.

Abstract: A four-wheel drive torque transfer mechanism splits torque from the transmission gearing section of a vehicle into a front-wheel torque and a rear-wheel torque, transmitting the front-wheel torque to the front-wheel drive shafts and the rear-wheel torque to the rear-wheel drive shafts. A central differential connected to the transmission gearing section distributes the torque from the transmission gearing section. A central differential limiting mechanism, provided between the input and output sides of the central differential, limits the rotary differential operation of the differential arrangement responsive to a control torque signal. Control gain values representing optimized turning characteristics are calculated for each of the turning conditions of the vehicle and stored in a memory. A controller for controlling the differential limiting mechanism reads the control gain values from the memory and calculates the products of detected turning conditions and the control gain values corresponding thereto. The controller further calculates the sum of the products and generates the control torque signal in accordance with that calculated sum.

Abstract: In a preferred embodiment, the present invention relates to automatic vehicle control systems for controlling individual wheel torque and steering angle. Control is provided in response to desired forward velocity, desired steering angle, actual angular velocities of each controlled wheel, actual vehicle yaw rate, and actual vehicle lateral acceleration. A command processor uses desired forward speed, desired steering angle, and lateral acceleration to compute command angular velocities for each drive wheel and the commanded vehicle yaw rate. Further, the command signal processor monitors a tire adhesion limit. If this limit is exceeded, command signal will be reduced.
