Description

This invention consists of AI functions installed in the car and omnidirectional sensors/cameras, etc. to ensure safe driving for elderly drivers who are worried about driving due to deterioration of physical strength and ability. The AI monitoring device constantly monitors obstacles such as vehicles and pedestrians approaching from the surrounding area, and if it detects a risk of collision, it notifies the driver in question and delays the driver's appropriate measures to avoid the collision. This relates to an electric vehicle that takes safety measures such as deceleration and stopping using the on-board four-wheel drive safety brake.

In Japan, the baby boomer generation born after the war has reached the advanced age of 75 years or older, and there is concern about the increased risk of traffic accidents. Measures to prevent traffic accidents among the elderly include cognitive function tests and driver's license tests. At the time of driver's license renewal, driving skill tests and senior citizen training are also conducted.At the same time, for elderly drivers who feel anxious about driving, safe driving support vehicles equipped with driving support functions such as collision mitigation brakes and sudden acceleration control devices are provided. A limited driving license system and voluntary return of driver's licenses have also begun.

In conjunction with the development of self-driving cars in which a system operates the car under specific conditions, efforts are also being made to prevent damage from collisions with vehicles, pedestrians, and other obstacles for ordinary cars. Although these cars are equipped with various safety driving support devices such as collision damage reduction brakes and devices to prevent accidents where the brake and accelerator pedals are pressed incorrectly, some elderly people who drive these cars are unsure of how the devices work. However, some drivers are not familiar with the operation, and safe driving support devices are not always utilized appropriately.

With the exception of some expressways, elderly car drivers in Japan have a difficult time running red lights due to declining physical strength and driving ability due to aging, in a poor road traffic environment where pedestrians and miscellaneous vehicles come and go. Careless mistakes such as overlooking a pedestrian or failing to stop temporarily without noticing a pedestrian crossing are common, and accidents such as driving the wrong way or pressing the brake and accelerator incorrectly are common.

When encountering heavy rain, typhoons, snowfall, dense fog, etc. due to recent sudden climate changes, many elderly people are not good at responding quickly and appropriately, including daily preparations for these weather disasters, and our country is an earthquake-prone country. Therefore, it is essential to take disaster prevention measures while driving in case of a major earthquake, tsunami, or volcanic eruption.

The silver electric vehicle for city use of this invention has an AI monitoring device installed on the vehicle that monitors the safety of the road, and a four-wheel drive system that can effectively cope with road conditions under weather conditions such as sudden rain or snowfall. The use of safety brakes enables safe driving, avoids traffic accidents, and ensures safe driving on the road.

The AI monitoring device 1 described in [0007] is comprised of an omnidirectional sensor/camera, etc. (GPU/image processing semiconductor = built-in AI function) mounted on the roof or lower side of the vehicle, and is capable of detecting cars, bicycles, etc. approaching from the surrounding area. Obstacles such as pedestrians and traffic lights are constantly monitored, and when the possibility of a collision is detected by AI, danger warning information is provided to the driver by voice from the information transmission terminal in the driver's seat. If danger approaches without a confirmation call or appropriate risk avoidance measures being taken, the system automatically engages the four-wheel drive safety brake 2 described in [0007] to decelerate and stop the vehicle on behalf of the driver. Such measures will be taken.

The above-mentioned four-wheel drive safety brake 2 eliminates the accelerator pedal that adjusts the speed of normal vehicle driving, and instead incorporates the control function of the electric vehicle's motor into the brake system, allowing motor-controlled gear changes with a single pedal. The device 3 and the brake control device 4 are integrated as functions that work together.

When the pedal of the four-wheel drive safety brake 2 integrated into one pedal is depressed with one foot (right foot), it operates as a foot brake 5, and the motor is also activated as an electric brake to decelerate and stop the vehicle. On the other hand, when you raise your foot on the pedal and release the pedal, the foot brake 5 is released, the automatic traveling device 6 is switched on, and the vehicle gradually automatically accelerates to a specified speed (assuming a maximum speed of 30 km/h or less) and stabilizes at the specified speed.

The foot brake pedal uses the right foot, which is used by many people, in case of an emergency stop while driving, and by eliminating the accelerator pedal, it prevents runaway accidents caused by pressing the brake and accelerator incorrectly.

This silver street electric vehicle is intended for elderly drivers who wish to drive safely at low speeds, and is intended to be a low-speed vehicle that runs at a maximum speed of 30 km/h or less (tentatively) on general roads in the city and suburbs, and on slopes. For safety, AI automatically adjusts the motor controller to maintain a constant speed, and if an abnormal situation such as an accident or lane departure occurs, an AI monitoring device activates and sounds an alarm, interlocking with the four-wheel drive safety brake. The car quickly slows down and stops.

This silver electric vehicle for street use supports the driver's appropriate safe driving operations and avoids accidents by using the functions of the AI monitoring device and four-wheel drive safety brake described in [0007] above in conjunction with each other. It can reduce the technical burden of operating drivers for safe driving, and can supplement the driving functions of recognition, judgment, and operation based on the driver's "awareness."

The above-mentioned "AI monitoring device" turns on the tail lights on behalf of the driver in order to avoid collisions with obstacles such as vehicles approaching from the lower part of the vehicle side or the rear, which is a blind spot from the mirror when turning right or left. It automatically flashes a danger warning signal to notify following vehicles and assist in collision avoidance.

The four-wheel drive safety brake pedal is a safe pedal that integrates an electric motor controller and a brake function, and can avoid the mistake of pressing the wrong pedal, which is a beginner's mistake for elderly drivers who are anxious about driving. This helps reduce technical concerns and prevents accidental accidents.

The adoption of a four-wheel drive vehicle for the city-driving silver electric vehicle of this invention is intended to prepare for traffic problems on volcanic ash roads due to the expected eruption of volcanoes such as Mt. Fuji, as well as wind and flood damage such as floods and snowfall, and earthquake disasters that have recently occurred frequently due to climate change. be.

The silver electric vehicle for city use of this invention is a four-wheel drive light electric passenger vehicle, and its appearance, structure, technical functions, etc. are not significantly different from those of ordinary electric vehicles. The onboard AI monitoring device consists of omnidirectional sensors, cameras, etc. (GPU/image processing system = built-in AI function) installed on the roof or lower part of the car body, and monitors cars, bicycles, pedestrians, etc. approaching from the surrounding area. Obstacles are constantly monitored, and if a collision is predicted to occur, danger warning information is provided to the driver via voice from an information transmission terminal installed in the driver's seat, and depending on the situation, four-wheel drive safety is activated. The brakes can be used to slow down and stop the vehicle to avoid traffic accidents.

The above-mentioned four-wheel drive safety brake, which integrates both accelerator and brake functions, is combined into a single pedal, and is installed under the right front of the driver's seat in a position that allows correct up and down operation with the right foot (dominant foot). Separately install a spare handbrake for use on the left side of the driver's seat (for left hand or left foot).
