Title: Alarming device for vehicle
Inventor: HATTORI YOSHIKAZU
IPC: G08G1/16
Filed: 1993-05-27
Abstract: PURPOSE:To generate an alarm at proper timing without giving physical disorder to a driver. CONSTITUTION:When there is a preceding vehicle, an inter-vehicle distance HW and the speed Vx of a driver's own vehicle are detected and whether the distance HW is less than a prescribed value L0 or not is judged (100 to 106). When the distance HW is less than the prescribed value L0, a relative speed V and relative acceleration G to the preceding vehicle are computed (108), and at the time of detecting that the acceleration G is more than a prescribed value and brake operation is not executed (110, 112), an alarm is generated (114). Since the processing is executed based upon such a driver's actual deceleration operation that even if relative speed is low when relative acceleration is high, the speed is immediately decelerated by brake operation, an alarm is generated to a driver at proper timing.

Abstract: PURPOSE:To obtain necessary emitting power by driving only a first current source, feedback- controlling the first current source by an optical detector at the time of reproducing, switching the first current source to control via a holding circuit and further, overlapping a second driving source at the time of recording or erasing. CONSTITUTION:At the time of the reproducing, a semiconductor laser 1 is emitted and driven only by a constant current source 2 for reproducing. Then, the laser 1 is continuously controlled by a feedback control system, which is composed of an optical detecting circuit 4, a comparator 7 and the constant current source 2 for reproducing, and constant power is kept. At the time of the recording, a switch element 10 is changed-over from the comparator 7 side to a holding circuit 9 side and an output from the circuit 9, which holds a comparing output at the time of the reproducing, goes to be effective. Then, a constant current flows to the semiconductor laser 1 by the constant current source 2 for reproducing. At such a time, a switch 8 is selected to a reference voltage VREf2 side and a current source 3 for recording is driven superimposed on the above-mentioned constant current. At the time of the erasing, a same condition is obtained, however, it is different that the switch 8 is selected to a VREf3 side. Thus, the control of reproducing power can be executed with high accuracy at a high speed and power for recording and erasing can be made stable.
