DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a car display lamp which sends thanks signal to a succeeding car for getting ahead of and letting cut into a line of cars.
BACKGROUND OF THE INVENTION
When drivers get ahead of and cut into a line of cars, it is a kind of courtesy for them to show their appreciation to a succeeding car in some way.
Conventionally, they raise their hand or turn on and off their turn signal lamps or head lamps to show their appreciation directly or indirectly.
DISCLOSURE OF THE INVENTION
In order to concentrate on driving, such actions should be easy and certain to convey their messages as much as possible. A driver, however, will be distracted by expressing thanks by raising hand and by flashing his turn signal lamps or head lamps. Those actions require extra operations beyond normal driving.
Further, even such actions are doubtful to convey the intention of the drivers with certainty.
In order to solve such problems, it is an object of this invention to provide a display lamp to convey appreciation of a driver to others with much easier and surer way with lesser extra operations beyond normal driving.
According to the present invention, there is provided a car display device which detects an on-off signal with a predetermined period to flash turn signal lamps of a car and actuates a display for a predetermined display period when one on-off signal is detected during a predetermined time. Alternatively, simultaneous flashing of turn signal lamps of a car can be used in spite of the display.
Control means comprises the first timer (23) which outputs duration signals (B, E) showing a duration in which the on-off signal is continuously output, the duration being determined by that first timer is reset and restarted at every level transfer of the on-off signal, with beginning to measure time in synchronization with a level transfer of the on-off signal with a predetermined period to flash turn signal lamps and measuring a first predetermined time which is longer than one period and shorter than two periods of said on-off signal, second timer (24) which outputs a reference signal (D) showing the reference time when a second predetermined time passed after the beginning of the duration shown by the duration signal B, by being reset and restarted in synchronization with the beginning of the duration of the duration signal (B) and by measuring the second predetermined time which is longer than the first predetermined time of the first timer and shorter than two periods of the on-off signal, and signal output means (25, 26) which outputs a display signal (G) for a predetermined display time to actuate the display device when it is judged from both the duration signal (E) and the reference signal that the duration is over at the reference time.
Alternatively, control means can also comprises timer means (32, 324, 230) which decides a duration in which the on-off signal is continuously output, the duration being determined by that the timer is reset and restarted at every level transfer of the on-off signal, with beginning to measure time in synchronization with a level transfer of said on-off signal and measuring a predetermined time which is longer than one period and shorter than two periods of the on-off signal, level transfer detection means (322, 324, 240) which detects the level transfer of the on-off signal while the timer means is measuring time in the duration, and signal output means (322, 250, 260) which outputs a display signal for a predetermined display time to actuate the display when the predetermined time has passed without any detections of the level transfer by the level transfer detection means.
Further, the constitution of another embodiment is characterized in that period detection means (322, 324, 280, 290) which detects a period of level transfer of the on-off signal to flash the turn signal lamps is comprised and that a predetermined time to measure time by timer means is set based on the period detection means. In this ease, the car display can b
