Turning direction indicator
First Claim
1. A turning direction indicator for use in a vehicle, for indicating a turning direction of the vehicle, the vehicle including a steering wheel, a speed meter, and a light source for a turn signal, the turning direction indicator comprising:
- an operating part;
a plurality of switch contacts to be brought into or out of electrical contact with each other, in response to operation of the operating part;
an angular velocity sensor for detecting an angular velocity of a turn of the vehicle, and outputting an angular velocity signal; and
a controller for controlling output of a drive signal, according to the electrical contact between the switch contacts and the angular velocity signal, the drive signal being for causing operation of the light source;
wherein the controller controls the output of the drive signal, according to the angular velocity signal and a speed signal, the speed signal being indicative of a speed of the vehicle and supplied from the speed meter.

Abstract
A turning direction indicator controls the operation of a light source for turn signals and indicates a turning direction of the vehicle. Switch contacts are brought into electrical contact with each other, responsive to operation of an operating part. An angular velocity sensor detects an angular velocity of a vehicle turning, and outputs an angular velocity signal. A controller controls the output of a drive signal for causing operation of the light source, according to the electrical contact between the switch contacts and the angular velocity signal. The controller controls the output of the drive signal, according to the angular velocity signal, and a speed signal indicating a speed of the vehicle. The controller controls the output of the drive signal, according to the relation between the set threshold value and the angular velocity signal, and the relation between the angular velocity signal and the speed signal.
