Description

Description: TECHNICAL FIELD The present invention relates to an apparatus for recording and reproducing braking operation of an automobile, particularly a motorcycle.

[Conventional technology]

Unlike the driving operation of a four-wheeled vehicle, the timing of braking operation of the rear and front wheels of a motorcycle is required.

In a motorcycle, the braking mechanism for the front and rear wheels is a separate system, and there is a risk of a fall when the front wheels are suddenly braked when running, and a fall of one revolution forward when the brakes are left unattended. Under such circumstances, handling of brake operation of a motorcycle is one of the important items in driving lessons at a driving school.

Because instructors cannot ride in motorcycle driving lessons,
Teaching brake operation is extremely difficult. In practice, the practice is to equip the motorcycle itself with a number of colored lights that can be seen from a distance and to turn on the colored lights in sequence in connection with the braking operation to determine the quality of the braking operation. However, it is almost impossible to judge important factors such as the timing of the brake operation with respect to the distance to the destination, the strength of the operating force, and the suitability of the braking force, and practically only the operation time is confirmed. For this reason, the trainee had to practice the brake operation repeatedly by learning it himself, and it took a long time to acquire it.

In order to solve this problem, a device was developed in a driving school to automatically memorize the brake operation performed by a trainee driving a motorcycle and reproduce and display the recorded content later to obtain appropriate teaching materials ( See Japanese Patent Application No. 61-270337 (Japanese Patent Publication No. 4-4197).

This device mounts the device body on the vehicle body, records the braking operation force within a fixed time until it stops by braking operation in relation to the traveling speed, and after stopping, reproduces the operation content graphically It is the one.

When instructing trainees using this device, in order to set the braking start point by the trainee's braking operation, the braking start point display cone and the stop instruction cone should be placed back and forth as appropriate on the driving lane in the driving school. The trainee himself / herself determines the passing of the braking start point and performs the braking operation, and also lights the signal light (incandescent light bulb) to give a braking instruction, and in response, the braking light provided to the vehicle lights up. The instructor visually confirmed the brake operation, obtained actual measurement values such as the time between the designated point and the stop point, and the distance, and used this as the basis for the instruction.

[Problems to be Solved by the Invention]

However, when using the above-mentioned training method, uncertainties associated with the judgment of the trainee and preparatory movements include the reaction of the brake operation, the operation time, the braking distance, etc., and there is also the problem that it is difficult to judge individual differences. Do you get it.

An object of the present invention is to arbitrarily issue a command of a braking start point and a command of instruction contents (straight ahead, right avoidance, left avoidance, etc.) to a signal light, confirm the lighting of the signal light, and record the brake operation performed by the trainee. It is an object to provide a device that automatically records the timing of transmission and the content of instructions and also displays the nerve reflex and operation ability of the trainee.
