Vehicle Capable of Low Noise Runs
First Claim
1. A vehicle capable of low noise runs comprising:
- an electric motor for driving the vehicle;
a sound generator arranged to generate simulated engine sounds outside the vehicle for pedestrians to hear the vehicle;
a decider arranged to decide whether or not to have the sound generator generate the simulated engine sounds; and
a controller arranged to change the level of the simulated engine sounds in accordance with a predetermined manner.

Abstract
A vehicle comprises electric motor, generator of simulated engine sounds, decider of whether or not to generate simulated engine sounds and controller of the level of simulated engine sounds. The controller smoothly increases level of simulated engine sounds upon decision of sound generation on detection of pedestrian, crosswalk, narrow road, or road with no sidewalk. The decider is responsive to vehicle navigation system, or ETC, or camera of EDR. EDR records the decision as circumstantial evidence. The decision may be optionally possible, but is forcibly made upon necessity. Simulated engine sounds can be greater than, or equal to, or less than real engine sounds. The controller makes a soft peak of simulated engine sound upon brake or accelerator operated. Balance of simulated engine sounds among front, rear, right and left of vehicle is changeable in response to shift lever or blinker lever operation. The decision is visually indicated inside vehicle.
