The design of an automobile is highly dependent on several factors. One of the biggest factors is its intended use. For example, a car designed for local driving may be fuel efficient, but less comfortable at high speeds. A sports car, on the other hand, has enhanced handling and a high-performance suspension system. Most automobiles need to be adaptable, so that they can fit a variety of uses.
Human circulatory system
The Human circulatory system is a complex system of blood vessels. They are made up of systemic aortic root, main and small arteries, capillaries, venules, and pulmonary artery roots. The heart is located at the top of the heart and provides mechanical propulsion to blood flow.
Blood is made up of oxygen-carrying erythrocytes, immunological white blood cells, and punctuating platelets. It also contains a fluid called plasma. This straw-coloured liquid carries many dissolved substances including carbon dioxide, glucose, and hormones.
Human steering system
A human-centered steering system can help reduce driver workload while increasing vehicle path-following performance. This novel system can be configured to give the driver a feedback on the steering gain, lateral deviation, and yaw error. The system also incorporates multi-layer cybersecurity. This system is designed to be secure and reliable for human drivers.
A human driver holds the steering wheel with one hand while using their other hand to move the vehicle. The natural frequency of the human hand is high enough to stabilize the vehicle motion, yet the steering wheel is not tightly gripped enough to fix the car at high speed.
Human transmission system
The transmission system in automobiles resembles the human heart, which initiates blood flow. Both systems perform the same task, but at varying rates. The engine in a vehicle runs at one to two thousand rpms, and the transmission changes gear ratios to maximize the engine’s power. Without these systems, a vehicle would not survive.
A typical automobile has one or more windows that open and close. This decreases the concentration field in the air near the driver, and increases it in the front. The outward flow decreases the concentration field at the front and rear of the car, enhancing the transmission from the driver to the passenger.
Human overdrive gears
The overdrive gears in automobiles work by adding effective ranges to the gears. For example, when the overdrive gear is engaged, a third and fourth gear in the vehicle will become a third-and-half gear and a fifth gear, respectively. This gives the driver more ratios and flexibility.
The first overdrive gears were manufactured in 1967 and were found in European cars. Later, they were manufactured by Laycock Engineering (later GKN Laycock), and are now found in some Ford, Lincoln, and Volvo cars. A mechanical unit was also produced by Fairey Engineering for the Land Rover.
