Abstract

PROBLEM TO BE SOLVED: To shorten braking distance to stop a car avoiding an obstruction with a driver feeling danger to suddenly brake during normal travel by installing a braking device shifting the gear of an automobile during forward travel into reverse so as to reversely rotate tires to stop the automobile. SOLUTION: In the case of a driver depressing a brake pedal with strong force sensing danger during forward travel, a clutch is automatically cut off in a manual vehicle to shift into reverse gear. In an automatic vehicle, on the other hand, in the case of traveling in the drive, second, low and neutral positions of the gear, the gear is automatically put into reverse. In both manual and automatic vehicles, tires are reversely rotated in association with engine torque from the instant of shifting into reverse gear to the stop of the vehicle, thus stopping the vehicle. Accordingly, even in the case of braking hard, braking distance is shortened without locking the tires, and the vehicle can be stopped avoiding an obstruction.

With conventional brakes, friction between all tires and the road surface is determined by using a hydraulic or pneumatic drum brake, a disc brake, or the like, regardless of whether the brake is sudden or normal. The car was stopped using it. The drum brake is a brake that stops the rotation by pressing a brake drum attached to wheels with a brake shoe. The disc brake is a brake that stops the rotation by sandwiching a disc attached to the wheel with a brake pad instead of the brake drum. Therefore, the brake stops the rotation of the tire, and the tire stops the car. However, when the driver suddenly feels danger while driving and suddenly brakes, the person reflexively and strongly depresses the brake pedal, so that the brake is applied too much and the rotation of the tire stops. That is, the tire locks. If the driver feels danger during normal driving and suddenly brakes, the brakes are too effective and the tires lock, and conversely, the distance until the car stops, that is, the braking distance increases, There was a problem that it was impossible to avoid obstacles.

When the driver feels danger while driving forward and depresses the brake pedal with a strong force, when the manual vehicle is running in the low, second, third, top, overtop and neutral positions , The clutch is automatically disengaged and the gear enters R (reverse). On the other hand, in automatic vehicles, the gears are driven, second,
If the vehicle is traveling at the low and neutral positions, the gear automatically enters R (reverse). In both manual and automatic vehicles, from the moment when the gear enters R (reverse), until the vehicle stops, the tire rotates backward with the rotation of the engine and stops the vehicle. A vehicle traveling forward has inertia working forward. Therefore, even if the brake is suddenly applied and the tire is locked and stopped, the vehicle moves forward while slipping due to momentum of inertia for a few seconds. If we were riding without fastening our seat belts, we humans would break through the windshield and be thrown out. To stop a car in such a state with the shortest braking distance, set the gear to R.
(Reverse) and forced to reverse the tire and stop. In other words, this is the most inertial stopping method. If the inertia force of the car moving forward disappears, the engine of the manual car stops and the car itself stops completely. In an automatic vehicle, the vehicle itself stops completely when the engine is stopped or the engine is running. If both the manual and automatic vehicles lose the inertial force to move forward, if the tire is rolling backward, it is dangerous because the car will now retreat. Therefore, the engine is stopped in a manual vehicle, the engine is stopped or the engine is stopped in an automatic vehicle, and the vehicle stops completely. In addition, even if a sudden brake is applied, the tire does not lock, so that the obstacle can be avoided by operating the steering wheel.

When the driver feels danger while driving backward and depresses the brake pedal with a strong force, when the manual vehicle and the automatic vehicle are both running in the R (reverse) and neutral positions, the driver is automatically turned on. The clutch is disengaged, the gear is 1 (low) in a manual car, and the gear is L (low) in an automatic car. In both manual and automatic vehicles, from the moment the gears go low, until the car stops, the tire turns forward and stops the car due to the rotation of the engine. This time we are driving backwards,
Inertia works backward. To stop a car in such a state with the shortest braking distance, set the gear to 1 (low),
There is no choice but to put it in L (low) and force the tire to roll forward and stop. This is also the most inertial stopping method. In addition, the tire is not locked even when the brake is suddenly applied, so that the obstacle can be avoided by operating the steering wheel.

It is to be noted that a brake operation other than a sudden brake, a brake operation when it is not necessary to use the braking rotation of the tire, that is, a speed reduction, a stop during an extremely low speed running, an emergency stop during an extremely low speed running, and a normal operation Can be stopped by a conventional stopping method using a hydraulic or pneumatic drum brake, a disc brake, or the like.

Since the rearward braking and the forward braking of the tire are performed with the rotation of the engine, in order to adjust the braking rotation speed and the braking torque of the tire, it is necessary to adjust the rotation speed and the torque of the engine. . The engine speed and torque are related to the running speed of the vehicle. For example, when sudden braking is performed during high-speed running, it is preferable that the number of revolutions and torque of the engine, such as high-speed rotation, medium-speed rotation, and low-speed rotation, are automatically adjusted. Thereby, the braking rotational speed and the braking rotational force of the tire can also be adjusted.

Even when sudden braking is performed, the tire is not locked, the braking distance is short, and obstacles can be avoided to stop. Further, even on an extremely slippery road such as a snowy winter road or an ice barn, the same effect can be obtained as when running on a normal road and suddenly braking. As a result, traffic accidents and the like that cause death by automobiles and the like can be drastically reduced.
