Can the Dash Cam Continue Recording After the Vehicle is Turned Off?

If the dash cam has a parking monitoring function, it can continue recording after the vehicle is turned off, but the recording time is not long. Since the dash cam's power is provided by the car, it can only operate when the car is running. Some dash cams have battery power, but the battery capacity is too small to support prolonged operation. Connecting the dash cam directly to the car battery will cause the battery to discharge continuously, affecting its lifespan. Functions and Categories of Dash Cams: Function: A dash cam is a device that records images, sound, and other relevant information during vehicle operation. Once installed, it can record the entire driving process in video and audio, providing evidence in case of traffic accidents. Categories: The parking monitoring function of dash cams comes in two types—one is continuous recording, and the other only activates short recording when the vehicle detects vibration. However, there are currently no dash cams capable of continuous long-term recording after the vehicle is turned off. Solutions for Parking Monitoring Power Issues: To enable parking monitoring, the dash cam must either have an embedded rechargeable battery or be connected to the ACC fuse for power. After the vehicle is turned off, it automatically enters parking monitoring mode, where sensors continuously monitor the vehicle's status. If an abnormality or vibration is detected, it automatically records and stores the footage separately. Compared to constant power connection, dash cams with parking monitoring connected to the ACC fuse are more power-efficient and less harmful to the car battery. However, if the vehicle remains unused for several days, the battery may still drain, making it difficult to start. Another method is using a power bank to supply electricity for parking monitoring. However, this approach has its drawbacks, primarily concerning the power bank's quality. If temperatures rise too high, the power bank could potentially explode, leading to more severe damage.

Where is the QR code located on a motor vehicle?

The QR code for motor vehicles can be viewed in the mobile app "Traffic Management 12123" and is usually found on the vehicle's accompanying documentation, such as the configuration sheet, which includes specific vehicle details and features a QR code. First, you can use your smartphone to view it in the "Traffic Management 12123" app (V2.8.1B274). The vehicle QR code contains information such as the issuing authority, a unique serial number, license plate number, as well as technical parameters of the vehicle and owner details. Open the "Traffic Management 12123" app on your phone, click on "Registered Vehicles" on the homepage, then navigate to the "Vehicle QR Code" section. Second, the standard motor vehicle QR code is typically located on the accompanying documents, such as the configuration sheet, which lists the vehicle's specific configurations and includes a QR code displaying detailed information about your vehicle. The specific applications of QR codes in vehicle management involve the administration of vehicle information, safety, inspections, approvals, and other related aspects. As a means of transportation, vehicles and their drivers are constantly in dynamic motion across time and space. The functions of the vehicle QR code include: Converting and storing vehicle-related information within the QR code; Automatically recording the vehicle's annual inspection documents via the QR code; Enabling traffic police to record vehicle violation penalties by scanning the QR code; Allowing vehicle owners to check annual inspection statuses via the QR code; Establishing a vehicle monitoring network through the QR code to ensure effective, real-time, and automated vehicle management. As a new automatic identification and information carrier technology, QR codes have been widely applied in fields such as national defense, customs, taxation, public safety, and transportation for automatic information storage, transmission, and anti-counterfeiting purposes.

Are Cars Front-Wheel Drive or Rear-Wheel Drive?

Currently, most cars on the market adopt a front-wheel drive (FWD) configuration, which means the engine is positioned at the front and powers the front wheels. Advantages and disadvantages of front-wheel drive: Advantages: The powertrain is compact, with shorter drive shafts, resulting in lower power output loss. In terms of handling, FWD vehicles inherently exhibit understeer characteristics, making them easier to drive. In terms of layout, the absence of a driveshaft running through the cabin allows for a lower center tunnel, maximizing interior space. Disadvantages: During acceleration, the front axle load decreases, reducing tire grip and affecting power output. Additionally, the front axle bears excessive load because the front wheels are responsible for both driving and steering. Due to the heavier front-end weight distribution, front tires wear out faster. The burden on the front axle during acceleration or braking is more pronounced, leading to more noticeable lift and dive effects, which compromise ride comfort. Rear-wheel drive (RWD) refers to a configuration where the engine is front-mounted but powers the rear wheels. Most racing cars use rear-wheel drive. Advantages and disadvantages of rear-wheel drive: Advantages: The front and rear wheels have distinct roles—steering and driving are separated, resulting in higher stability at high speeds and better climbing ability. The weight distribution is more balanced, enhancing handling, which is why most racing cars still use RWD. Disadvantages: The presence of a driveshaft creates a center tunnel bulge in the cabin floor, affecting interior space and layout. Power loss is greater since the engine's power must travel through the driveshaft to reach the driven wheels, making RWD vehicles generally less fuel-efficient than FWD ones.

How Long is the Break-in Period for a Vehicle?

The break-in period for a new vehicle is generally 1,000 to 3,000 kilometers. Purpose of the break-in period: The break-in period primarily allows the various components of the vehicle to fully contact, frictionally adapt, and settle into their optimal positions. During this period, the vehicle's parts enhance their ability to adapt to operational conditions, and any surface irregularities on the components are smoothed out through contact. Precautions during the break-in period: Avoid full load. The vehicle's load during the break-in period should not exceed 75% of its rated capacity. Maintain smooth starts and avoid sudden acceleration. Since the components are still in the break-in phase, excessive loads and high speeds can intensify impact forces on the parts, potentially causing damage rather than reducing surface roughness. Shift gears promptly while driving. Avoid prolonged use of a single gear. Start in a low gear and gradually shift to higher gears for progressive driving. Avoid scenarios like high speed in low gear or low speed in high gear to ensure even wear on transmission components such as gears and shafts. Choose smooth roads to minimize excessive vibration, collisions, or emergency braking. Control your speed carefully, ideally maintaining it between 50-80 km/h. Avoid long-distance trips. Extended driving during the break-in period increases continuous engine operation time, accelerating component wear. Do not change the oil prematurely. Follow the manufacturer's recommended oil change schedule for the break-in period. Always warm up the engine before driving. Ensure the coolant temperature reaches at least 40°C. Warming up allows sufficient lubrication time, especially for turbocharged models, which require at least one minute of warm-up before driving.

What is the fault code for the oxygen sensor?

Oxygen sensor refers to a sensor that monitors exhaust gases, responsible for measuring the oxygen content in vehicle emissions. Normally, after the vehicle exhaust is emitted, the mixture sends a signal to the computer to determine the size of the oxygen sensor's fault code, allowing the computer to readjust the fuel supply. The fault codes for the oxygen sensor include: P0139 to P0147, specifically as follows: 1. P0134 indicates no signal from the upstream oxygen sensor. 2. P135 is a fault in the first sensor of the first group of the oxygen sensor's heating circuit. 3. P0141 indicates a fault in the oxygen sensor heater circuit.
