Abstract: Based on detected information from a start sensor, a rotational speed sensor (or a vehicle speed sensor), and an accelerator opening sensor, a simulated sound selector device controls a simulated sound source device to generate a simulated sound signal corresponding to an operating condition of an electric vehicle when it starts, runs and is accelerated or decelerated, and also controls a sound level switcher device to adjust the level of the simulated sound signal. The simulated sound signal which is generated by the simulated sound source device and adjusted in level by the sound level switcher device is amplified by amplifiers, which drive respective loudspeakers to produce simulated sounds. The sound level switcher device is also controlled based on an ambient noise level detected by a noise sensor.

Abstract: An interface for a supervised multiple input, audible warning system is disclosed. The interface continuously monitors or supervises a plurality of circuits between a control unit and an alarm unit for electrical faults. Each circuit represents a separate alarming condition. All the circuits are coupled to but normally isolated from each other and a common circuit for driving a piezoelectric device. The isolation is accomplished by means of a semiconductor switch normally reverse biased. The semiconductor switch prevents the supervising current of one circuit from driving the piezo by isolating all possible flow paths to all circuits without current flow in the alarming direction. Upon sensing an alarming condition, the direction of the current in the alarming circuit reverses resulting in forward biasing the semiconductor switch. The current in the alarming circuit, no longer isolated from the common circuit, actuates the common circuitry necessary for generating the audible warning.
