<p>PURPOSE:To enable optimum cancellation according to travelling speed by calculating a cancelling angle according to the vehicle speed, while constituting a device to generate the output for putting out the light of a turn lamp when a steering angle by a steering wheel angle detector reaches the cancelling angle. CONSTITUTION:When a turn switch 1 is operated to change a traffic lane in the travelling of a vehicle, a flashing signal is generated from a calculating device 4 to a drive circuit 5 to flash a turn lamp 6. Then, a cancelling angle corresponding to the vehicle speed detected by a vehicle speed detector 2 in the operation of turn switch 1 in said device 4 is read out of a preset table, while whether or not a reversal angle of a steering wheel obtained from the output of a steering wheel rotation angle detector 3 reaches the cancelling angle is monitored. When the reversal angle is judged to reach the cancelling angle, the flashing operation of turn lamp 6 is stopped.</p> |
