Automotive MCU stands for Motor Control Unit, which is the module that controls the operation of the motor. The role of MCU: MCU (Micro-Controller-Unit), or microcontroller, is primarily used to connect and control various peripheral circuits and interface circuits in automobiles. Generally speaking, the most important factors are reliability and temperature range. The temperature range for civilian-grade MCUs is typically 0-70°C, industrial-grade -20-85°C, and automotive-grade -40-85°C. Classification of automotive MCUs: By application: Dedicated type: The hardware and instructions are designed for specific purposes, such as tape recorder mechanism controllers, printer controllers, motor controllers, etc. By data bit width: Based on the width of the bus or data register, microcontrollers can be further classified into 1-bit, 4-bit, 8-bit, 16-bit, 32-bit, and even 64-bit microcontrollers.

Will the car get damaged if left outside in the sun?

Leaving the car outside in the sun will not cause immediate damage, but prolonged exposure can lead to aging of the vehicle body. Here are some relevant points about prolonged sun exposure for vehicles:1. Correct driving after sun exposure: Open the car doors to create air convection inside the vehicle, allowing the hot air to be quickly expelled. When turning on the air conditioning, wait for about five to six minutes until the engine stabilizes before activating the compressor.2. Cooling the interior: Mix water and alcohol in a 10:1 ratio and spray it inside the car. Since alcohol evaporation absorbs a large amount of heat, the interior temperature will become cooler within just a few tens of seconds.

What are the functions of car polishing?

Car polishing mainly has two functions: 1. By polishing, the oxidized, dull, or scratched vehicle paint surface is treated to remove oxides and corrosive substances, thereby improving the cleanliness of the paint surface; 2. It can protect the car paint surface, providing waterproofing, acid rain resistance, UV protection, anti-static, and other effects. More information about car polishing is as follows: 1. The downside of polishing and waxing is that polishing can thin the car paint. If the operation is not skillful, it may polish down to the primer. If waxing is too frequent, it may cause scratches on the paint surface due to dust. Therefore, experts advise that the number of polishing times in a car's "lifetime" should preferably not exceed five; 2. Car polishing is a method of removing surface scratches and rough areas on the car paint using polishing wax and a polishing machine.

How to Determine if a CVT Transmission is Slipping?

CVT transmission slipping manifests as follows: 1. When accelerating sharply, the RPM does not increase smoothly but suddenly jumps, for example, from 2500 RPM to over 3000 RPM, without a corresponding increase in vehicle speed. 2. During startup, pressing the accelerator pedal causes the RPM to rise quickly, but the vehicle speed does not increase accordingly, resulting in slow movement. 3. Fuel consumption increases significantly because the vehicle fails to accelerate properly, leading the driver to unconsciously press the accelerator harder, naturally increasing fuel consumption. 4. When climbing hills or under heavy load, the engine RPM is high, but there is a noticeable lack of power, and the vehicle speed increases slowly.
