MCU refers to the unique power electronic unit in new energy vehicles. By receiving the vehicle driving control instructions from the VCU, it controls the motor to output the specified torque and speed, thereby driving the vehicle. Its function is to convert the DC electrical energy from the power battery into the required high-voltage AC electricity and drive the motor to output mechanical energy. Additional information is as follows: The Vehicle Control Unit (VCU), Motor Control Unit (MCU), and Battery Management System (BMS) are the most critical core technologies, significantly impacting the vehicle's power performance, fuel economy, reliability, and safety! 1. Vehicle Control Unit (VCU): The VCU is the core electronic control unit responsible for overall vehicle control decisions. It is generally equipped only in new energy vehicles, as traditional fuel-powered vehicles do not require this device. 2. Motor Control Unit (MCU): The MCU is a unique core power electronic unit in new energy vehicles. By receiving driving control instructions from the VCU, it controls the motor to output the specified torque and speed, driving the vehicle. 3. Battery Management System (BMS): The BMS can improve battery utilization, prevent overcharging and over-discharging, extend battery life, and monitor battery status.

What is the general tire pressure for cars?

There are specified pressure values for car tires. The standard tire pressure for passenger cars is within the range of 2.3-2.5 bar, with a maximum not exceeding 3.0 bar and a minimum not below 2.1 bar. According to the regulations and requirements of the international standard GBT2978-2008, the tire pressures for different tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; The maximum air pressure should not exceed 3.5 bar. Normal tire pressure in winter: In winter, the tire pressure should be based on the standard tire pressure of the car, with an appropriate increase of about 0.2 bar. Normal tire pressure in summer: Generally, the lower limit of the standard tire pressure for car tires is sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures.

Where to Place Reflective Stickers on Helmets?

Place them on the helmet. When illuminated by motor vehicle or other vehicle lights, they will automatically reflect light, thereby alerting drivers to take timely evasive action and ensure safety precautions. Types of Riding Helmets: Half-shell riding helmets are categorized into road-specific (no brim) and road-mountain dual-use (with detachable brim). Some riders also use helmets similar to those for baseball or roller skating. Full-shell riding helmets resemble motorcycle helmets and are generally used by downhill or trials biking enthusiasts. How to Wear a Riding Helmet: The helmet should be worn level, not tilted forward or backward. Some riders feel the front brim obstructs their view and tilt the helmet upward for better visibility. However, removing the brim can achieve the same effect.

Is a Truck Crane Considered Special Equipment?

It has been clearly established that a truck crane is not considered special equipment. Truck cranes and tire cranes are two entirely different things and should not be confused. Introduction to Truck Cranes: A truck crane is a type of crane mounted on either a standard automobile chassis or a specially designed automobile chassis. It features separate compartments for the driving cab and the crane operation cab. The advantage of this crane is its excellent mobility and quick transfer capability. The drawbacks are that it requires outriggers during operation, cannot carry loads while moving, and is unsuitable for use on soft or muddy terrain. Working Principle of a Truck Crane: Below the crane boom, there is a rotating drum wound with a steel wire rope. The rope passes through a pulley at the top of the next boom section to extend the upper boom section, and so on. When retracting, the drum reverses to retract the steel wire rope, and the boom retracts under its own weight. This rotating drum is driven by a hydraulic motor, which is why you can see two hydraulic hoses, but they should not be mistaken for hydraulic cylinders.
