What does detachable intelligent four-wheel drive mean?
2 Answers
Detachable intelligent four-wheel drive means the following: Precise control based on information: Detachable intelligent four-wheel drive refers to a system where the vehicle can precisely control the intelligent transfer case to distribute controllable torque to all four wheels based on wheel slip or steering information, thereby improving acceleration, stability, and fuel economy. Ability to switch when needed: The intelligent four-wheel drive system only switches to four-wheel drive when necessary, while remaining in two-wheel drive mode under other conditions. The system automatically switches between two-wheel drive and four-wheel drive modes based on the driving conditions, without requiring manual intervention. Intelligent four-wheel drive differs from part-time four-wheel drive, which requires manual switching between two-wheel and four-wheel drive modes, and full-time four-wheel drive, which operates in four-wheel drive mode under all conditions. When the vehicle is parked, the intelligent four-wheel drive system delivers very low or zero torque to the front wheels, enhancing convenience and comfort during operation.
I previously drove an SUV equipped with this four-wheel drive system, and the most intuitive feeling was how smart it is. Normally driving on paved roads in the city, it automatically disconnects the rear axle power and becomes a front-wheel drive vehicle. The dashboard shows the two-wheel drive status, and a full tank of fuel can last an extra 70-80 kilometers. When encountering rainy days with waterlogged roads or suburban gravel roads, all four wheels reconnect almost instantly, and the steering wheel feels noticeably more stable. The core of this system lies in the intelligent clutch module inside the transfer case, where wheel speed sensors and the onboard computer communicate in real-time, making millisecond-level decisions on whether to engage four-wheel drive. Last winter, I saw other cars fishtailing on icy roads, but my car passed through steadily without even triggering the ESP, which was very reassuring.
