What is the Difference Between 360-Degree Surround View and Rearview Camera?

360-degree surround view provides an ultra-wide perspective, while the rearview camera, also known as the reverse visible system or onboard monitoring system, serves a different purpose. The main differences between 360-degree surround view and rearview camera are as follows: 1. Imaging: The rearview camera is specifically designed for reversing and only displays the vehicle's front and rear conditions. In contrast, the 360-degree surround view captures a full circle of the vehicle's surroundings, showing road conditions all around. 2. System Differences: The 360-degree camera employs a fisheye panoramic imaging optical system with no central blind spots, offering 3 million pixels for high-definition output. The rearview camera system is widely used in various large, medium, and small vehicles for reversing or driving safety assistance. 3. Principle Differences: The rearview camera system uses a TFT true-color display with anti-magnetic treatment to eliminate signal interference and flickering. It can receive two video inputs simultaneously, play VCDs and DVDs without requiring a decoder. The 360-degree camera synthesizes images from four 180-degree wide-angle cameras installed on the front, rear, and sides of the vehicle into a bird's-eye view displayed on the in-car monitor.

Why is the car air conditioning cooling but not draining water?

Car air conditioning cooling without drainage may be due to a blocked drain hole, resulting in poor cooling effect. Additional information: 1. Inspection method: Check if the air conditioning drain hole is blocked; Lift the floor mat to see if there is water accumulation under the passenger seat; Use a thermometer to measure the air outlet temperature to see if it is normal. 2. Common causes of blockage: After disassembling and reassembling the dashboard at a repair shop, the drain pipe may not be installed correctly, causing water to flow into the car, with the common symptom being water marks on the carpet. If it is a new car, the evaporator core may be internally blocked, or the drain outlet of the evaporator core may not have been properly treated during production; The connection between the drain outlet of the evaporator core and the rubber drain pipe may have come loose or is not properly connected. 3. Solution: If you encounter the problem of the air conditioning not draining, immediately go to a 4S shop or repair point to find a professional technician to handle it.

Can out-of-town vehicles leave during Beijing's traffic restriction hours?

Out-of-town vehicles cannot leave during Beijing's traffic restriction hours. The specific restriction times are: 1. Passenger vehicles: Weekday morning and evening peak hours from 7:00 to 9:00, and 17:00 to 20:00 (no restrictions on weekends and statutory holidays); 2. Freight vehicles: Daily from 6:00 to 24:00. Below are the restricted areas for out-of-town vehicles in Beijing: 1. Weekday peak hours from 7:00 to 9:00 and 17:00 to 20:00: Prohibited from driving on the main roads, auxiliary roads, and roads within the Fifth Ring Road. 2. Weekdays from 9:00 to 17:00: Must comply with the city's odd-even license plate restriction rules, with the same restrictions as Beijing-registered vehicles, covering the main roads, auxiliary roads, and roads within the Fifth Ring Road. 3. Daily from 6:00 to 22:00: The entire main road of the Second Ring Road is prohibited for passenger vehicles with license plates issued by other provinces, regions, or cities (including temporary plates).

Why is the Beidou System Mandatory for Heavy Trucks?

The reasons why heavy trucks must be equipped with the Beidou system are as follows: 1. The installation of the Beidou satellite positioning device facilitates driving data statistics: It can scientifically record and analyze a large amount of data such as vehicle speed, location, mileage, fuel consumption, driving time, driving direction, anti-theft alarms, etc., providing a basis for high-level decision-making. 2. Installing the Beidou satellite positioning device can improve work efficiency: After installation, the dispatch center can formulate optimal scheduling plans, reduce the workload of dispatchers, achieve scientific scheduling, greatly improve resource utilization and turnover rates, and provide comprehensive and efficient management for vehicles in industries such as buses, taxis, logistics vehicles, and engineering vehicles. 3. Installing the Beidou satellite positioning device can enhance driving safety: The backend dispatch center of the Beidou satellite positioning device can strictly monitor various safety issues such as vehicle speed, route, fatigue driving, and emergency assistance, ensuring greater safety for people and property. 4. Installing the Beidou satellite positioning device is beneficial for corporate cost control: The device enables real-time tracking and positioning of vehicles, supervision of vehicle operating status, monitoring of the rationality of fuel consumption and refueling amounts, comparison of various expenses with actual costs, and establishment of important bases for vehicle management systems, which helps in corporate cost control.

Is Dragging the Car Chassis a Serious Issue?

It is a serious issue; it can cause the exhaust pipe to rupture because the exhaust pipe is relatively fragile and can easily break upon impact; it can lead to deformation of the lateral arm, affecting the tire alignment parameters; it can also result in brake fluid line leakage and oil pan rupture. Methods to handle car chassis dragging: 1. Evacuate passengers: On muddy sections where dragging is likely, passengers can exit the vehicle to raise the chassis, then reboard after passing the muddy area. 2. Measure clearance: Be aware of your vehicle's minimum ground clearance. Minimum ground clearance refers to the smallest distance between the lowest part of the car and the road surface, typically 250mm for large vehicles and 130mm for small vehicles. 3. Visit a repair shop promptly: If dragging has occurred but there is no oil (engine oil or fuel) or fluid leakage, no sudden abnormal noises, no steering deviation, and no unusual vibrations, the situation is not yet severe. Simply go to a professional repair shop for inspection, and you can drive with peace of mind after confirmation. 4. Drive slowly: Slow down when approaching areas where dragging might occur. If you hear any noise from the chassis, reverse or find another route instead of forcing your way through.

What is the speed limit for buses on highways?

For small passenger vehicles on highways, the minimum speed is generally 60 km/h if there are no special speed limit signs. After entering the highway via the ramp, drivers should accelerate to 60 km/h as soon as possible. Highway minimum speed limit regulations: Article 78 of the "Regulations for the Implementation of the Road Traffic Safety Law" states: Vehicles on highways should drive in designated lanes, with a maximum speed not exceeding 120 km/h and a minimum speed not less than 60 km/h. Small passenger vehicles on highways must not exceed 120 km/h, other motor vehicles must not exceed 100 km/h, and motorcycles must not exceed 80 km/h. If there are two lanes in the same direction, the minimum speed for the left lane is 100 km/h; if there are three or more lanes in the same direction, the minimum speed for the leftmost lane is 110 km/h, and the middle lane is 90 km/h. If the speed indicated by road speed limit signs conflicts with the above lane speed regulations, drivers should follow the speed indicated by the road signs. Therefore, the minimum speed on highways is 60 km/h. Highway minimum speed penalty rules: Driving at a speed 20% below the minimum limit on highways will not incur penalties; According to Article 90 of the "Road Traffic Safety Law of the People's Republic of China," if a vehicle's speed is more than 20% below the stipulated minimum speed under normal driving conditions, the driver will be fined 200 RMB and receive 3 penalty points; No penalties will be imposed if the vehicle's speed is below the minimum limit due to road construction, traffic congestion, or adverse weather conditions like rain or fog. According to relevant provisions of the "Road Traffic Safety Law," driving too slowly on highways is punishable. On highways, vehicles moving too slowly can easily cause rear-end collisions. Article 78 of China's "Road Traffic Safety Law" clearly states that highway speeds should be marked by lanes, with a maximum speed not exceeding 120 km/h and a minimum speed not less than 60 km/h. This is also why low-speed vehicles like tricycles and farm vehicles, with maximum speeds not exceeding 60 km/h, are not allowed on highways.
