摘要： A drive system is provided for a utility vehicle and includes an alternating-current (AC) motor for providing a drive torque. An AC motor controller receives a battery voltage signal, throttle pedal position signal, brake pedal position signal, key switch signal, forward/neutral/reverse (FNR) signal, and run/tow signal indicative of the utility vehicle being configured to be driven and being configured to be towed. The AC motor controller generates an AC drive signal for the AC motor, wherein the AC drive signal is based on the battery voltage signal, throttle pedal position signal, brake pedal position signal, key switch signal, FNR signal, and run/tow signal.

摘要： A horn activation system for a lightweight utility vehicle can comprises a pressure sensitive horn switch (PSHS) operably connected to a horn button. The horn button is operable with the PSHS such that pressing the horn button compresses the PSHS. The horn activation system additionally can comprise an electronic switching device communicatively connected to the PSHS. The electronic switching device is responsive to a horn activation signal transmitted by the PSHS when the PSHS is compressed in response to depression of the horn button. The horn activation system further can comprise a horn configured to receive a current flow resulting from the electronic switching device closing a horn control circuit upon receipt of the horn activation signal.

摘要： A lightweight utility vehicle brake lighting system comprising a brake pedal position sensor, a controller and a brake light circuit. The brake pedal position sensor senses the position, e.g., amount of depression, of a vehicle brake pedal. The controller of interprets a brake pedal position signal from the brake pedal position sensor to determine the position of the brake pedal. When the controller determines that the brake pedal has been depressed to initiate a braking operation of the vehicle, the controller transmits a brake light signal to an electronic switching device, such as a relay switch, of the brake light circuit. Upon receipt of the brake light signal, the electronic switching closes to complete, or close, the brake light circuit to enable a current flow through the brake light circuit, thereby illuminating at least one brake light of the vehicle.

摘要： A digitally controlled and free-running multivibrator for the power supply is used to supply machining power pulses of predetermined ON and OFF time duration. The pulse output from the digital multivibrator is passed through at least one intermediate drive stage to trigger an electronic output switch, which is operatively connected both to a main DC power source and the gap, to actually provide the machining power pulses thereto. Responsive to a predetermined drop in gap voltage, a digitally predetermined extended OFF time is added.

摘要： A protection circuit which senses and responds to an output transistor failure to provide appropriate power interruption to protect an electrical discharge machining apparatus. The circuit receives an input of either standard or reverse polarity from the gap. This signal is passed through a comparator stage where it is compared with a preset voltage level. Further inputs are provided in accordance with the polarity setting and from the multivibrator in such manner that an appropriate phase relationship is maintained depending on the preset polarity. A control signal is then generated to control a transistor switching device with an interrupt signal thus being furnished to turn-off the power supply. Also included in a different embodiment of the invention is a system whereby, in a multiple gap output module power supply, responsive to failure of an output transistor in any one of the output modules, the entire power supply is cut off.
