Abstract
A warning device (610) includes a horn A (630) for generating a first horn sound having a volume level satisfying the legal standard and a horn B (632) for generating a second horn sound satisfying at least one of a condition that it has a volume level equal to or lower than that of the first horn sound and a condition that it is of a type different from that of the first horn sound.
Claims23
A vehicle warning device, the warning device being for a vehicle mounted with a driving electric motor and an internal combustion engine, the device comprising:
- a first horn portion for generating a first horn sound having a volume level satisfying the legal standard;
- a second horn portion for generating a second horn sound satisfying at least one of a condition that it has a volume level equal to or lower than that of said first horn sound and a condition that it is of a different type from said first horn sound;
- a control portion for controlling said second horn portion, wherein
- said control portion controls said second horn portion to generate said second horn sound during traveling by a driving force of said driving electric motor or at a start time, and
- an illuminance detecting portion for detecting illuminance around said vehicle, wherein
- said control portion suppresses generation of said second horn sound according to said detected illuminance.
