Abstract

To provide a technique capable of avoiding an accident caused by a wrong way of stepping on an accelerator of a vehicle driven by a person close to dementia, a physically handicapped person or an old person.SOLUTION: When an accelerator is depressed, a vehicle starts slowly, and when the accelerator is further depressed, the vehicle stops. When a driver releases his / her foot and further depresses the accelerator for several seconds, vehicle speed becomes conventional high speed. Alternatively, when the accelerator is depressed, the vehicle starts slowly, and when the accelerator is further depressed for several seconds, vehicle movement becomes conventional movement, and when the foot is released and the accelerator is further depressed, the movement stops.SELECTED DRAWING: None

Description

Technical Field

[01] Regarding the movement of the way of stepping on the accelerator when a person close to dementia, a physically disabled person, or an elderly person is driving. Background Art and Problems

[02] In the prior art, even if the accelerator is mistaken for the brake, it moves immediately, and if it is stepped on strongly, the speed increases.

Claims

1. When the accelerator is depressed, it starts moving slowly and stops when further depressed. When the foot is lifted and the accelerator is further depressed and a few seconds pass, it reaches the conventional high speed.

2. When the accelerator is depressed, it starts moving slowly, and after a few seconds of further depression, it moves in the conventional manner and stops when the foot is lifted and the accelerator is further depressed.
