摘要： An independent wheel torque control algorithm is disclosed for controlling motor torques applied to individual electric motors coupled to vehicle wheels in an electric vehicle. In a first range of vehicle states, vehicle steerability is favored so that the operator of the vehicle suffers little or no longitudinal propulsion loss while steering is enhanced. In a second range of vehicle states, vehicle stability is favored. According to embodiments of the disclosure, a desired yaw moment is computed and then may be reduced in magnitude due to system limitations, electrical or friction limits, which prevents the desired yaw moment from being fully realized.

摘要： A system for distributing propulsion to front and rear axles of a vehicle includes: a front axle motor coupled to the front axle and a rear axle motor coupled to the rear axle. An electronic control unit (ECU) electronically coupled to the motors commands the rear axle motor to increase torque supplied to the rear axle during understeer and commands the front axle motor to increase torque supplied to the front axle during oversteer. A method to distribute propulsion to front and rear axles of a vehicle includes estimating actual yaw rate, estimating desired yaw rate, providing electrical energy to the front axle motor during oversteer, and providing electrical energy to the rear axle motor during understeer. Additionally, electrical energy may be extracted from the rear axle motor during oversteer and electrical energy may be extracted from the front axle motor during understeer.

摘要： Electrodes providing excellent recording and physical stability. Electrodes that include a plurality of small teeth that possess a novel design shape and orientation are disclosed. The shallow and relatively long teeth preferably run parallel to the rim of the electrode that presses against the patient's skin. When the electrode is twisted onto skin, the teeth penetrate nearly horizontally under the stratum corneum. The electrodes cause minimal discomfort to the patient since the teeth do not extend to the pain fibers which are located in deeper layers of the skin. The electrodes may house a diversity of electronic components to enable numerous experimental and medical implementations. The electrodes may also be used wirelessly without electrode leads. The electrodes may be fabricated using precision photo-chemical etching techniques that are well known in the art. An electrode installation device that preferably employs the electrodes is also disclosed.
