Abstract: A method of controlling vehicle stability includes the steps of obtaining a measured yaw rate from the vehicle, generating a predicted yaw rate based on the measured yaw rate, calculating a first error signal based on a difference between the measured yaw rate and a desired yaw rate, calculating a second error signal based on a difference between the predicted yaw rate and the desired yaw rate, and sending a selected one of the first and second error signals to a yaw controller to conduct stability control. The predicted yaw rate can be generated by sending the measured yaw rate through a lead filter.

Abstract: A hybrid vehicle includes an internal combustion engine and an electric motor for powering two wheels. The wheels are separated by a common differential. A controller is provided to execute certain commands related to the braking of the vehicle. During braking of the two wheels, one wheel exceeds its slip limit, causing the wheel speed of that wheel to drop and pull-down as the wheel catches the ground. In response to the one wheel pulling-down, the controller commands a reduction of brake actuation force on the pulled-down wheel, and also commands a reduction of a rate of increase of the brake actuation force on the non-pulled-down wheel. Simultaneous pull-down or pull-up of the wheels is thereby inhibited as brake actuation forces on each wheel are continued to be controlled in response to the other wheel's activity.

Abstract: The utilization in a vehicle of the third derivative of rotational speed differences to enable early detection of the likely development or actual initiation of a condition involving wheel slip or loss of traction between the wheel and the surface over which it is traveling and to provide information to means to prevent the development of or reduce, inhibit, limit, eliminate, or control that condition is materially superior to the previously-disclosed methods intended for those purposes. The utilization of the third derivative of rotational speed differences for the indicated purposes produces highly useful and unexpected results and effectively addresses the problem of the detection of slip or loss of traction by means of a method of analysis not previously recognized or applied to that problem.

Abstract: In a control for a four-wheel drive vehicle that is able to travel in a non-differential mode in which differential rotation between front wheels and rear wheels is limited, it is determined whether a drive train is placed in a twisted state where a twisting torque resulting from a twist accumulated in the drive train is larger than or equal to a predetermined torque while the vehicle is cornering in the non-differential mode, and braking force is applied to the front wheels by a wheel brake device when it is determined that the drive train is placed in the twisted state.

Abstract: A system, method, and computer program product for detecting and compensating for a traction steer event is provided. A first wheel speed of a first driven wheel is compared with a second wheel speed of a second driven wheel to determine whether a wheel slip condition has occurred. If a wheel slip condition is determined to have occurred, a current operating state of a vehicle is compared to an expected operating state of the vehicle to determine if a traction steer event has occurred. If a traction steer event is determined to have occurred, brake pressure is selectively applied to the first or second driven wheel to compensate for the traction steer event.
