FCW on the car dashboard stands for Forward-Collision-Warning, which is the Forward Collision Warning System. It primarily uses a radar system to continuously monitor the vehicle ahead, assessing the distance, position, and relative speed between your car and the vehicle in front. The function of FCW: When the system detects a potential collision risk, it will illuminate a warning light on the full LCD dashboard and emit an alert sound to prompt the driver to reduce speed. However, the FCW system itself does not take any braking measures to avoid collisions or control the vehicle. Levels of collision warning systems: The three levels of automotive collision safety warnings are: The first and second levels are safe distance warnings and fixed-time warnings, which dynamically adjust based on your vehicle's speed—the faster the speed, the longer the warning distance. The third level is collision warning, with a fixed warning time, measuring the relative speed via radar, which can be understood as the speed difference between the target vehicle and your car. If your car's speed is greater than the vehicle ahead's speed, a collision is possible, and the greater the speed difference, the longer the warning distance.

What are the four main types of new energy vehicles?

New energy vehicles mainly include fuel cell electric vehicles, hybrid vehicles, hydrogen-powered vehicles, and pure electric vehicles. Here is an introduction to new energy vehicles: Pure electric vehicles: Pure electric vehicles refer to vehicles that use on-board power as the energy source, with motors driving the wheels to meet all safety regulations. Due to their relatively smaller environmental impact compared to traditional vehicles, their prospects are widely optimistic, although current technology is not yet mature. Hybrid vehicles: Hybrid vehicles refer to vehicles whose drive systems consist of two or more individual drive systems that can operate simultaneously. The driving power of the vehicle is provided by the individual drive systems alone or in combination, depending on the actual driving conditions of the vehicle. Fuel cell electric vehicles: Fuel cell electric vehicles are essentially a type of electric vehicle. In terms of body, power transmission system, and control system, fuel cell electric vehicles are basically the same as ordinary electric vehicles, with the main difference lying in the working principle of the power battery.

How Often Should Differential Oil Be Changed?

Differential oil should be changed every three years or 60,000 kilometers. The differential lock is the locking mechanism of the differential, used to lock the inter-wheel or inter-axle differential to handle situations where one or more wheels lose traction and cannot get free. A standard differential allows the left and right wheels to rotate at different speeds, but when one wheel spins freely, the other wheel on good road surface also loses torque, causing the vehicle to lose driving power. Here is additional information: Function of the differential lock: The differential lock works by locking the differential housing and the half-shaft into one unit when one driving wheel slips, disabling the differential function and transferring all torque to the other driving wheel. Locking methods: Forced locking, high-friction self-locking, jaw-type, Torsen, and viscous coupling. The jaw-type is commonly used in medium and heavy-duty trucks.

How to Register a Parallel Imported Vehicle?

To register a parallel imported vehicle, you need the customs declaration form, the vehicle inspection report, and 3C certification. Once all the documents are prepared, you can proceed to the vehicle management office for registration. Here are the specific advantages of parallel imported vehicles: Price Advantage: Parallel imported vehicles eliminate many intermediate steps. Additionally, parallel import dealers are not restricted by manufacturers in pricing, giving them more flexibility, which results in significant price discounts. Typically, parallel imported vehicles are 10%~20% cheaper than their China-spec counterparts. Model and Delivery Time Advantage: After new vehicles are launched overseas, they may not be immediately available in China due to manufacturers' strategic planning or domestic certification requirements. However, as parallel imported vehicles, they can be freely purchased overseas and then shipped to China for sale, significantly reducing the waiting time for new models. More Varied Configurations: You can purchase overseas models that are not available in China. Generally, to align with the Chinese market positioning strategy, manufacturers make certain adjustments or modifications when importing overseas models into China.
