Abstract: A traction control system includes a master cylinder containing brake fluid, braking devices configured to apply braking force to associated wheels of the vehicle, a brake pedal operable by a driver of the vehicle to generate braking force by pressurizing the brake fluid, and means for storing pressurized brake fluid to apply and temporarily hold a braking force at a slipping driven wheel. A method of providing traction control for a vehicle includes manually switching the vehicle from a normal operating mode to a traction control mode, sensing the slippage of a driven wheel, applying a braking force to the slipping driven wheel in response to a driver of the vehicle pressing a brake pedal, maintaining the braking force on the slipping driven wheel after the brake pedal is released, and gradually releasing the braking force as the slipping driven wheel gains traction.

Abstract: Methods and systems for supplying auxiliary electrical power to a controller during power loss are described hereinabove. The system is powered by a primary power source, and includes a controller and a winding load that are both powered by the primary power source, and a switching device. When the primary power source is disconnected from the controller and winding load, the winding load continues to residually exercise to generate residual electrical power. The second switching device then channels the residual electrical power to the controller for a period of time at an acceptable level.

Abstract: The present invention provides an electronic circuit and EMI countermeasure for an automotive electronic control unit that provides a maximum amount of EMI protection under normal operating conditions, i.e., ambient temperatures. The effectiveness of the EMI countermeasure is limited at extremely high temperatures. The electronic circuit and EMI countermeasure optimizes the effectiveness of EMI countermeasures as a function of temperature to improve performance under normal conditions.

Abstract: A steering angle sensing system includes at least one steering angle sensing device for outputting an analog signal representative of a steering angle position of a steering wheel. A first processor is operably coupled to the at least one steering angle sensing device and is disposed proximate the at least one steering angle sensing device. The first processor receives the analog signals output by the at least one steering angle sensing device, computes a steering angle value based upon the analog signals, and outputs a pulse width modulated signal representative of the computed steering angle value. A second processor is disposed non-proximate the at least one steering angle sensing device and is operably coupled to the first processor to thereby receive the pulse width modulated signal representative of the computed steering angle value.
