The "Classification of Automotive Driving Automation" is one of the foundational standards within China's intelligent connected vehicle standard system. It will support the subsequent introduction of laws, regulations, and mandatory standards related to autonomous driving in China. Below is a partial introduction to the levels of driving assistance: 1. Content: Includes definitions of driving automation, principles for classifying driving automation, elements for dividing driving automation levels, definitions of each level of driving automation, processes and methods for determining driving automation levels, and technical requirements for each level of driving automation. 2. Classification: Autonomous driving is divided into a total of 6 levels from L0 to L5, with L0 representing traditional human driving without automation, and L1 to L5 further classified according to the maturity of autonomous driving.

As an enthusiast who deals with new cars every day, the driving assistance levels refer to the international classification system for vehicle automation, ranging from Level 0 to Level 5. The car I drive is Level 2, equipped with features like lane-keeping and adaptive cruise control, which helps me with steering and speed on highways, but I still need to stay focused on the road. The higher the level, the more the system intervenes; Level 0 is fully manual with no assistance; Level 1 might only have warning sounds or braking; Level 2 is the common combination of automated functions; Level 3 and above can take over most operations, but the driver must be ready to take control at any time; Level 5 is fully autonomous, requiring no human intervention. I think understanding these levels is crucial when choosing a car that fits your driving habits. For example, Level 1 or 2 is practical for city commuting, offering both safety and fuel efficiency. Nowadays, more and more new cars come with these features, making driving easier and more enjoyable for me.

What is the Rear Axle Ratio?

Rear axle ratio is an important parameter of the engine, commonly known as the rear axle ratio, with its academic name being the final drive ratio. Below are specific details about the rear axle ratio: 1. Key Factors: The rear axle ratio is related to gears. The power output from the engine and transmission acts on the drive shaft, which rotates to transfer power to the pinion gear of the final drive, driving the ring gear of the final drive to rotate, and subsequently turning the axle shafts. 2. Calculation Formula: Number of teeth on the ring gear ÷ Number of teeth on the pinion gear. In simple terms, when the drive shaft rotates N times to make the axle shaft rotate once, this N represents the rear axle ratio.

What Are the Symptoms of a Bad Half Shaft?

The symptoms of a bad half shaft include abnormal shaking and unusual noises while driving. The half shaft, also known as the drive shaft, is the component that transmits torque from the transmission and differential to the drive wheels. It has universal joints at both ends, which connect to the differential gear and the wheel hub bearing inner ring via splines on the universal joints. Depending on the support type, half shafts can be either fully floating or semi-floating. A fully floating half shaft only transmits torque and does not bear any reaction forces or bending moments, making it easy to install and remove. A semi-floating half shaft, on the other hand, transmits torque while also bearing all reaction forces and bending moments. It has a simpler support structure and lower cost, but it is more difficult to remove and install.

Differences Between Transverse and Longitudinal Engine Layouts

The differences between transverse and longitudinal engine layouts are as follows: 1. Different placement directions: A transverse engine is placed horizontally, requiring the transmission to be placed horizontally alongside it; a longitudinal engine is placed vertically, with the transmission located behind the engine. 2. Different power output directions: The power transmission direction of a transverse engine is typically perpendicular to the car's forward direction; the power transmission direction of a longitudinal engine is usually parallel to the car's forward direction. 3. Different drivetrain configurations: Transverse engines are used in front-wheel-drive vehicles; longitudinal engines are used in rear-wheel-drive vehicles. 4. Different suspension systems: Transverse engines use MacPherson strut suspensions; longitudinal engines use multi-link or double-wishbone suspensions.

What are the causes of a weak starter operation?

The causes of a weak starter operation include the following points: 1. Insufficient battery charge or oxidized wire terminals: When turning the starter switch to the start position, if the engine rotates when decompressed but the starter does not rotate or struggles when not decompressed, it is likely due to insufficient battery charge or oxidized wire terminals. 2. Poor contact between the brushes and the commutator, or partial short-circuit in the motor winding: If the starter rotates very slowly when decompressed and sparks occur at the commutator, it is mostly due to worn brushes or commutator causing poor contact, or short-circuiting of the commutator copper segments. 3. Armature rubbing against the magnetic poles or damaged coil insulation: If the starter rotates very slowly when decompressed and produces noise or smoke, it is mainly caused by the armature rubbing against the magnetic poles or damaged coil insulation.

What are the reasons for a car engine lacking power?

Car engine lacking power is caused by: 1. Clogged fuel lines or insufficient fuel supply, especially at higher RPMs when greater load and fuel volume are required. Restricted fuel flow leads to decreased engine power and poor performance; 2. Fuel injector leakage or nozzle blockage results in poor atomization, causing incomplete combustion after fuel injection and engine power loss. The car engine is the power-generating device for automobiles, serving as the heart of the vehicle that determines its power performance, fuel efficiency, stability, and environmental friendliness. Based on different power sources, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems.

How to Cancel the Auto-Locking Function on the Cruze?

The auto-locking function on the Cruze can be canceled either through the settings on the car's dashboard or by using a car diagnostic tool. The auto-locking feature is a safety function that typically activates when the vehicle reaches a certain speed, primarily to prevent doors from suddenly opening while driving, thereby avoiding potential accidents. The Cruze has a body length, width, and height of 4666mm, 1807mm, and 1460mm respectively, with a wheelbase of 2700mm. It features a 4-door, 5-seat sedan body structure, with a front suspension type of MacPherson independent suspension and a rear suspension type of torsion beam non-independent suspension.
