Abstract: A dual haptic system control system in a vehicle includes a first haptic controller disposed on a steering wheel of a vehicle and a second haptic controller disposed on a console separated from the steering wheel. The first haptic controller is a mini-haptic interface that controls a smaller set of functions than the second haptic controller. Redundancies are built in between the first and second haptic controllers so that at least some of the functions of the first haptic controller are also controlled by the second haptic controller. The steering wheel is devoid of stalk switches, with the first and second haptic controllers, in conjunction with switches and menu keys on the steering wheel controlling these functions. The display illustrates the functions that are operable from the present state of the system as buttons that contain both text (of the button function) and graphics (of the button function and any sub-functions available).

Abstract: A crystal-less keyless entry system includes a microprocessor or micro controller, a timing circuit, and a radio frequency circuit. The timing circuit is a unitary part of the microprocessor. When configured to compensate for power up delays in the radio frequency circuit, the microprocessor outputs data having stretch times that compensate for power up delays in the radio frequency circuit. The stretch times do not substantially vary the substantially constant bit time periods of the output data. When configured to detect a switch activation, the microprocessor transmits a bit within a period that includes a debounce time interval. The method of transmitting data using a crystal-less remote keyless entry system includes selecting a bit from a data stream and encoding the bit with a Manchester like encoding process. The Manchester like encoding process debounces a switch between logic levels of the encoded data.

Abstract: A crystal-less keyless entry system includes a micro controller, a timing circuit, a memory, and a radio frequency circuit. The memory and timing circuit are a unitary part of the microprocessor. The memory is programmed with a compensation that adjusts an output frequency of the timing circuit such that the output frequency of the timing circuit does not coincide with a frequency discontinuity that occurs within an output of the timing circuit. A method of calibrating the crystal-less keyless entry system includes programming the temperature compensation and a voltage compensation in the memory.

Abstract: A method of calibrating a remote keyless entry system adjusts a timing circuit that is a unitary part of a microprocessor. The method drives a plurality of inputs to the microprocessor to a logic state, monitors the output of the microprocessor, and programs a calibration factor within the microprocessor based on the output of the microprocessor. The calibration factor controls an output frequency of the timing circuit.
