Car OTA upgrade refers to Over-the-Air firmware and software upgrades. Introduction to OTA: OTA not only provides a more convenient way to upgrade vehicles, but also allows consumers to experience a smarter and more convenient car usage experience. The full English name of OTA is Over-the-Air Technology, which means wireless download technology. The role of OTA: It can quickly fix system defects. When traditional cars encounter system defects during user driving verification, the only solution is for the car manufacturer to initiate a recall program, where users return to the factory for a unified system upgrade after receiving the recall notice. However, OTA technology can remotely and quickly complete defect fixes through data packages, greatly avoiding the risks associated with factory recalls that could last for months.

As someone who works with cars year-round, I've noticed many car owners are quite curious about OTA updates these days. Simply put, it's as convenient as updating your phone's operating system, except the target is your car. The vehicle can automatically download update packages when connected to the internet, eliminating the need for a special trip to the 4S shop. My car just received an update recently – the central control screen got a fresh interface, and the air conditioning control logic was optimized. This update method is particularly suitable for improving software functions, such as fixing navigation map errors or enhancing driving safety configurations. However, it's important to note that updates should ideally be performed when the vehicle is parked with sufficient battery power. If an update fails, restarting the vehicle's infotainment system usually resolves the issue.

I've been driving an electric vehicle for three to four years and have personally experienced the convenience brought by OTA updates. Essentially, it's about directly patching the vehicle's software via mobile networks, much like how WeChat updates automatically. After the last upgrade, my car suddenly gained a battery preheating function, improving winter range by 10%. Manufacturers can fix system vulnerabilities anytime, such as optimizing braking programs, which is far more convenient than traditional recalls. However, it's important to read the upgrade notes carefully—once, an update popped up just as I was in a hurry to leave, and I had to wait a full half hour. Nowadays, most new cars support OTA, so it's a feature worth considering when purchasing a new energy vehicle, as it saves hassle and time in the long run.

Friends often ask me what OTA in cars is. It's essentially Over-The-Air update technology. You've seen phones updating systems via Wi-Fi, right? Cars work the same way. It mainly transmits data packages through 4G/5G networks without requiring any external devices. What I love most are the new features after updates, like last month's update that enabled the dashboard to display real-time energy consumption distribution. Manufacturers can use this method to remotely adjust power parameters and even improve acceleration performance. However, downloads can be slow with poor signals, so I recommend connecting to Wi-Fi in the garage for updates. Keeping the system updated is also important for extending the lifespan of vehicle equipment.

Do I Need to Empty the Tank When Switching from 95 to 92?

It is not necessary to empty the tank when switching from 95 to 92 gasoline. Different composition content: 92 gasoline is composed of 92% isooctane and 8% n-heptane, while 95 gasoline consists of 95% isooctane and 5% n-heptane. Different anti-knock properties: The gasoline octane rating represents its anti-knock properties. A higher octane number indicates better anti-knock performance, with 95 gasoline having higher anti-knock properties than 92 gasoline. Different prices: 95 gasoline is slightly more expensive than 92 gasoline. Different power performance: 95 gasoline, with its higher octane value, is suitable for engines with higher compression ratios. This is because as the engine speed increases, the ignition timing in the cylinder advances. When the speed reaches a critical point, premature combustion of the air-fuel mixture in the cylinder may occur before ignition. 92 gasoline has a relatively lower octane value compared to 95 gasoline, resulting in slightly weaker power performance.

Do Small Yellow Spots on Car Paint Need to Be Treated?

Yes, they need to be treated. Below is relevant information on dealing with small yellow spots on car paint: Yellow spots caused by dust and impurities: When a car is driven in areas with heavy dust, dust and impurities can accumulate on white paint surfaces. Some impurities are stubborn and cannot be removed with regular cleaning, such as asphalt and bird droppings. These sticky impurities require specialized cleaning agents for soaking, stain removal, and rinsing to completely eliminate them. Yellow spots caused by paint aging: If the car paint surface is exposed to prolonged sunlight and rain without timely care, the paint can easily age and develop spots. Some cars parked for extended periods or soaked in acid rain may even suffer severe corrosion. In such cases, the paint surface needs pathological treatment, which involves using polishing wax to grind and polish the affected paint surface.

Can I Replace Just One Car Tire?

It is possible to replace just one car tire, but the new tire must have a tread groove depth close to that of the other tire on the same axle. Otherwise, it may cause issues such as vehicle deviation. Tires on the same axle should be of the same specification, structure, manufacturer, and tread pattern, including load index and speed rating. It is recommended to replace at least two tires and install them on the same axle. Below is additional information: Replacing a problematic tire: If the car is new and has not been driven much, you only need to replace the problematic tire, as the tires on the same axle will have similar wear. Replacing a pair of tires: If the tires have been driven for tens of thousands of kilometers but do not yet need replacement, and only one tire has an issue, replacing just one tire can cause uneven height, vehicle bumpiness, or deviation at higher speeds. Therefore, in such cases, it is best to replace a pair of tires.

What Causes the ABS and EPS Lights to Illuminate?

ABS and EPS lights may illuminate due to faults in components such as wheel speed sensors, ABS wiring, ABS pump, pressure modulation solenoid valves, or the ABS control module. How ABS Works: During braking, the ABS system rapidly determines wheel lock-up status based on speed signals from each wheel speed sensor. It then closes the normally open inlet valve for the locking wheel to maintain braking force. If the wheel continues to lock, the normally closed outlet valve opens, allowing brake fluid to return directly to the reservoir through the pipeline, rapidly reducing braking pressure on that wheel to prevent complete lock-up. This keeps braking at the optimal point (20% slip ratio S), achieving maximum braking effectiveness and driving safety. Functions of ABS: 1. Maximizes brake effectiveness, reducing braking time and distance. 2. Effectively prevents vehicle skidding and fishtailing during emergency braking, ensuring good driving stability. 3. Allows steering during emergency braking, maintaining good steering control. 4. Avoids severe friction between tires and road surface, reducing tire wear.
