What are the six subsystems of a vehicle?

The six major subsystems of a car include the engine system, transmission system, braking system, suspension system, running system, and electrical system. As the core power source, the engine system generates mechanical energy by burning fuel to drive the vehicle forward, with key components including the crank-connecting rod mechanism and the valve mechanism. The transmission system is responsible for transmitting engine power to the wheels, covering components such as the clutch, gearbox, and drive shaft, ensuring efficient power adaptation to different road conditions. The braking system achieves deceleration and stopping through friction devices, serving as a critical safeguard for driving safety, with modern models typically equipped with ABS anti-lock braking functionality. The running system includes components such as tyres and wheels, which directly contact the ground, support the vehicle's weight, and facilitate power transmission and directional control. These systems operate synergistically to ensure safe driving and comprehensive functionality, with regular maintenance of each subsystem being essential for prolonging the vehicle's service life.
