What is the Principle of Haval Snow Mode?

[DiTucker]

Haval Snow Mode works by utilizing computer-controlled transmission to start the vehicle in second or third gear, ensuring smoother starts on icy or snowy roads. This reduces torque output and minimizes tire slippage on slippery surfaces. Snow Mode is a specialized driving mode managed by traditional mechanical systems, designed to decrease the likelihood of tire slippage on smooth, snowy terrain. It achieves this by limiting throttle opening to control engine power output, preventing sudden bursts of power that could lead to skidding. Typically, many vehicles are equipped with both "Sport Mode" and "Snow Mode" options, allowing drivers to select the appropriate driving mode based on environmental conditions. This ensures both driving enjoyment and safety. "Snow Mode" incorporates automated programming to start in second gear, preventing wheel spin when starting on icy or slippery surfaces, thereby enhancing vehicle control in snowy conditions.

I've been driving the Haval H6 for over three years, and the snow mode primarily relies on altering the engine and transmission's operational logic. Once activated, the system automatically limits torque output in lower gears, using second gear to start and prevent tire slippage on icy surfaces. At the same time, the traction control system becomes more sensitive, intervening with braking at the slightest detection of tire spin. The transmission also delays upshifting, maintaining higher RPMs without sudden speed surges, which is particularly stable when climbing snowy slopes. Actually, four-wheel-drive models distribute more power to the rear wheels, but even the two-wheel-drive version sees a noticeable improvement in snow handling thanks to this electronic control logic.

Last time I drove my friend's Big Dog to Changbai Mountain, I specifically tested the snow mode. The core of this feature is to reduce the vehicle's sensitivity to the accelerator pedal, preventing sudden power bursts that could cause skidding when you don't press too hard. The transmission proactively selects a higher gear to start, similar to manually starting in second gear. The ABS and electronic stability systems are also tuned to be more aggressive, intervening as soon as the wheels show any sign of locking. The chassis control computer even fine-tunes braking force in real-time based on tire slip rates, making it feel like each wheel has different braking force, which helps keep the car from veering off course.

Simply put, the vehicle's computer takes a three-pronged approach: the engine deliberately limits low-RPM torque output to prevent wheel spin and snow digging; the transmission delays shift timing to maintain smoothness; and the electronic systems enhance coordination. When activated during winter descents into underground parking ramps in northern regions, you can distinctly feel the throttle response becoming duller but remarkably stable.
