Stable current control to an inductive load uses a digital driver having registers loaded with load control parameters from a microprocessor. The parameters, along with a counter responsive to clock pulses, control a pulse period and a pulse width which are used to operate an FET in series with the load to control load current. Current mode control develops a decreasing current limit voltage in each pulse period by decrementing a down counter at a rate and from an initial value commanded by the microprocessor, and converting the value to an analog current limit signal. The signal is compared to a load current feedback signal and the pulse width is truncated if the load current reaches the current limit signal.

A system for anti-lock brake and traction control has a control circuit comprising a microprocessor on a silicon die. Inputs from several variable reluctance wheel speed sensors are multiplexed to a single channel on the same die for signal processing including diagnostics, A/D conversion, square wave generation for each sensor by a state machine, end wheel speed determination from the square waves. The state machine algorithm tracks signal peaks and valleys and uses a dual hysteresis method of generating output transitions to capture all cycles of a signal having single cycle anomalies while rejecting noise. A single rear wheel sensor having twice the frequency of front wheel sensors for equal wheel speeds is processed twice as often as each front sensor. The diagnostics include detecting sensor and harness short and open circuits by comparison of signals to programmable thresholds and fault timing and latching by gauging open and short signals against programmable time limits. Common mode noise rejection is accomplished by detecting common mode aberration and disabling an A/D converter during the aberrations.

An event counter is disclosed which, in one embodiment, provides a reaction timer to time a user's response time to an event. In a second embodiment, the event counter provides a counting device to count the number of occurrences of events or the magnitude of an event. The invention uses a commercially available stopwatch to time the response time. The start/stop switch of the stopwatch is connected to a signal generator such as a piezoelectric element. In one variation, the internal piezoelectric element used as a beeper in the stopwatch is used as the signal generator. In a second variation, the event timer is further provided with a circuit to allow a higher voltage LED to be driven by a lower voltage of the system battery. In yet another variation, the event timer further includes a random delay circuit to randomly delay the start time of the stopwatch. Random delay is provided without a microprocessor by using a variable current switch and two RC circuits having different tau values.

The present invention discloses a circuit for providing a variable output signal in response to a physical parameter sensed by a sensor in the circuit, preferably a force sensing resistor. The current mirror may consist of two transistors having common bases. Flow of current through the first transistor flows through the sensor and through a parallel resistor. This current is mirrored in a second transistor which provides flow of current which may either be used as an output signal or, more preferably, as a base current for a transistor which is used to control output signal voltage. The circuit uses the current mirror in connection with the sensor to eliminate the need for a negative voltage supply. The circuit may further advantageously contain a voltage limiter module which is used to limit the voltage which may be applied across the sensor if the range of input signals or the desired range of output signals exceeds the sensor's capability. The voltage limiter module establishes a fixed voltage across the sensor which is lower than the expected input or the desired output voltage ranges.

Faulty operation of a two-lead wheel speed sensor in a vehicle control system is detected and distinguished from transients by measuring a common mode voltage of the sensor and applying such voltage to a window comparator. Analog-to-digital conversion circuitry for capturing wheel speed signals is disabled so long as the measured voltage falls outside the comparator window. When the measured voltage is outside the comparator window for at least a given time limit, an open circuit fault condition is indicated. Additionally, the sensor lead voltages are compared to threshold voltages; when both voltages exceed the thresholds for at least a given time limit, a short circuit fault condition is indicated. The windows, thresholds and time limits are programmable by the vehicle control system computer.

The invention includes a direct current energy source monitor which automatically detects the nominal voltage of the direct current energy source to which it is attached. The invention further includes a direct current energy source monitor which is self-powered from the direct current energy source being monitored. The multiple nominal voltage direct current energy source monitor includes an analog-to-digital converter configured to measure voltage from a direct current energy source being monitored and generate a digital output corresponding thereto. The apparatus includes a programmable control device configured to receive the digital output from the analog-to-digital converter and to look up a nominal voltage corresponding to the digital output, and is further configured to calculate a relative charge of the direct current energy source as compared to a full charge on the direct current energy source. The direct current energy source monitor can include a voltage controlled oscillator configured to receive the voltage of the direct current energy source being monitored and generate a frequency output proportional to the received voltage. The programmable control device is configured use the frequency output to determine the received voltage from the direct current energy source.
