What Principle Does the Reversing Radar Operate On?

Reversing radar systems utilize ultrasonic signals, which are controlled by the microcomputer inside the reversing radar host. Through the process of transmitting and receiving signals by the probes, the system calculates the distance to obstacles by comparing the signal's round-trip time and then issues different alarm sounds via the alarm device. Below is a related introduction to the reversing radar system: 1. The reversing radar system consists of the reversing radar ECU, the reversing radar buzzer, and several (usually 4) reversing radar sensors installed on the (rear) bumper. If a rear camera is installed, it will provide an image of the rear area of the vehicle on the navigation screen. 2. When the vehicle is shifted into reverse gear, the reversing radar ECU uses ultrasonic sensors to monitor the area around the rear bumper. If an object is detected within the monitored area, the audible alarm device inside the instrument cluster will sound a warning. The system can detect relatively hard solid obstacles as well as objects like wire mesh and fences. The detection range of the two side sensors is an area 60cm from the corners of the bumper. When the detected distance is less than 20cm on the side or less than 30cm directly behind the center, the sound signal will become continuous to prevent a collision with the bumper.

Can You Turn Off the Engine in Neutral (N) Gear for Automatic Transmission?

You cannot turn off the engine in Neutral (N) gear for automatic transmission vehicles. For safety reasons, an automatic transmission car must be shifted into Park (P) gear before turning off the engine. The correct procedure for turning off the engine is: 1. Press the brake pedal; 2. Shift into N gear; 3. Engage the handbrake; 4. Release the foot brake and ensure the vehicle does not move before shifting into P gear; 5. Complete the engine shutdown. Both P gear and N gear disconnect the engine and wheel transmission system from operation. The only difference is that when the engine is off, the vehicle can be pushed freely in N gear, while in P gear, the vehicle cannot move. N gear is one of the three standard gears in automatic transmission models, located between Reverse (R) gear and Drive (D) gear on the gearshift console. Essentially, it is the neutral gear in the transmission, designed to cut off power transmission between the input and output shafts inside the gearbox.

Where is the Engine Exhaust Pipe Located?

The exhaust pipe of a car is located at the rear right side of the vehicle. Its low position serves to reduce vibration and noise, facilitate installation, and prolong the lifespan of the exhaust muffler system, thereby enhancing noise reduction effectiveness. Function of the Exhaust Pipe: The primary function of the exhaust pipe is to reduce engine noise and emissions of pollutants. Structure of the Automotive Exhaust System: The structure of a car's exhaust system is highly complex and not merely a simple pipe. The core components include the catalytic converter and the muffler. The catalytic converter transforms harmful gases such as CO, HC, and NOx emitted from the vehicle's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction processes.

Why does the car shake at idle but not while driving?

Car shaking at idle but not while driving is usually caused by excessive carbon deposits or spark plug issues. It can also be due to unstable oil pressure or aging engine components. When the car is running in a natural state without shifting gears or accelerating, steering wheel vibration is referred to as idle shaking. Below are the common causes of idle shaking: 1. Excessive carbon deposits inside the engine: During startup, carbon deposits absorb some fuel, leading to an overly lean air-fuel mixture. Once the carbon deposits become saturated with gasoline, the engine starts operating normally. However, when the mixture is ignited, the gasoline absorbed by the carbon deposits is sucked back into the cylinder by vacuum pressure, resulting in an overly rich mixture. This alternating lean and rich condition causes engine shaking. 2. Prolonged use of spark plugs can lead to increased spark plug gaps or excessive carbon buildup on the ignition points. These issues can cause poor sparking or insufficient ignition energy, resulting in cylinder misfires, reduced power, and engine shaking. 3. If the throttle body, air filter, spark plugs, and carbon deposits are all in good condition, the fuel supply system should be checked. Insufficient fuel pump pressure can also lead to reduced engine power and shaking.

Is Minor Transmission Oil Seepage Serious?

Automobile oil seepage is a normal phenomenon. If it's minor seepage, it's not a big issue; but if it's oil leakage, then it's more serious and should be repaired immediately. Most oil seepage occurrences are caused by seal corrosion and aging, especially in vehicles that have been used for a long time. Below is relevant information about automobile oil seepage: 1. Automobiles are consumables. With prolonged use, the sealing components in various parts will harden and age, losing their original elasticity. Under the high-intensity working conditions of the transmission, seals will gradually shrink, harden, and may eventually break, leading to transmission oil seepage or leakage, which is unavoidable. 2. Minor transmission oil seepage is not a serious issue, but you should keep an eye on it and have it addressed during your next visit to the shop. If the transmission exhibits more severe oil leakage, it is necessary to promptly go to a 4S shop or a professional auto repair shop for maintenance or replacement. Otherwise, insufficient oil in the transmission can lead to inadequate lubrication, accelerated wear, rough gear shifting, weak acceleration, unusual noises, jerking, and other issues. In severe cases, it may cause the transmission to seize up and become damaged.

Is making a U-turn at a red light considered running a red light?

If the U-turn signal is red, making a U-turn is considered running a red light. According to the "Road Traffic Safety Law," this violation incurs: 6 penalty points and a fine of 200 yuan. If there is no U-turn signal, and the gap is marked with a dashed line, the U-turn is not affected by the traffic signal and does not require crossing the pedestrian crossing. If the gap is marked with a solid line, the U-turn must cross the pedestrian crossing and is subject to the traffic signal. Making a U-turn directly may result in being photographed or penalized by on-site traffic police. When making a U-turn that requires crossing the pedestrian crossing, yielding to pedestrians is necessary: Pedestrians walking on the right side of the road's crosswalk, not reaching the centerline of the road. Vehicles on the left side of the road should slow down and proceed only after ensuring safety. Pedestrians waiting outside the boundary line of the motorized and non-motorized lanes. If they have not entered the roadway, vehicles should slow down and proceed only after ensuring safety. If pedestrians cross the boundary line between the motorized and non-motorized lanes, vehicles failing to stop and yield is a violation and should be penalized. When pedestrians enter the motorized lane via the crosswalk, vehicles must slow down and proceed only after ensuring safety. Failure to stop and yield is a violation and should be penalized. Pedestrians waiting at the centerline of the road without entering the vehicle lane. Vehicles failing to stop and yield is a violation and should be penalized. Pedestrians crossing the centerline of the road into the vehicle lane. Vehicles failing to stop and yield is a violation and should be penalized. Roads with a median strip separating pedestrians. When pedestrians are waiting in the median area, vehicles must slow down and proceed only after ensuring safety. Permissible U-turn scenarios: Intersections with U-turn signs allow U-turns: If there is a clear U-turn sign at the intersection, a U-turn is permitted. If there is a U-turn signal, follow the signal's instructions. If there is no signal, proceed with the U-turn without obstructing other vehicles or pedestrians. Intersections without explicit "No U-turn" or "No Left Turn" signs allow U-turns: If there is no explicit prohibition, a U-turn is allowed. "No explicit prohibition" means the absence of "No U-turn," "No Left Turn," or solid centerlines. Yellow grid lines also permit U-turns: Yellow grid lines indicate no-stopping zones at intersections prone to congestion, important entrances, etc. Stopping on these lines (including waiting for traffic lights) is a violation. However, U-turns are permitted in yellow grid zones unless there is a center divider. Intersections with U-turn signals: If a U-turn signal is present, follow it—green means U-turn is allowed. Simultaneous "No Left Turn" and "U-turn Allowed" signs: U-turns are permitted, but left turns are prohibited. Note that "No U-turn" is not the same as "No Left Turn." Precautions when making a U-turn at intersections: Observe road markings. If the line is solid, U-turns are prohibited under any circumstances. Continue driving to find a suitable U-turn location. If there is a "No Left Turn" sign, even without a "No U-turn" sign, U-turns are not allowed at that intersection, as U-turns inherently involve a left turn. U-turns must be made from the innermost left-turn lane. If in the second left-turn lane, U-turns are not permitted at that intersection. Always yield to straight-moving vehicles. Only proceed with a U-turn if it does not interfere with straight-moving traffic; otherwise, you bear full responsibility for any accidents. Near intersection stop lines, lanes often have guiding arrows. The leftmost lane is not always a left-turn lane. If it has a straight arrow, U-turns are prohibited even without explicit "No U-turn" signs.
