The most annoying thing for people in winter is snowfall, because snow can make driving difficult, especially in the cold north. The snow-covered road section is not only difficult to drive, but there are also certain misunderstandings. Let the Xiaobian introduce several major misunderstandings for driving under the ice-snow road section.
Misunderstanding 1: On the ice and snow road, the rear drive is better than the front drive
Although the rear-wheel drive sedan has better grip when accelerating, the front-wheel drive is more in line with people's driving habits, so the front-wheel drive on the ice and snow roads is better than the rear-wheel drive. Because the front wheels of the front-wheel drive are both steering wheels and drive wheels, they have good direction guidance. Since the front center of gravity of the front-wheel drive is relatively high at the start of acceleration, the load on the front wheels is better, and it is less likely to slip. The front and rear wheels of the rear-wheel drive are responsible for steering and driving, respectively, so it is easy to have uncoordinated movements on slippery roads, and it is more likely that the head and sideslip will occur.
Myth 2: Distress in the snow, ABS can shorten the braking distance
The function of ABS is mainly to make the wheels do not lock when braking, so that the vehicle can still turn to avoid obstacles when it is in a sudden braking, and try to prevent the car from slipping when braking, so ABS can make the driver rest assured that Heavy braking. However, in snow or sand, the braking distance may be longer due to the accumulation of snow and sand in front of the tire.
Misunderstanding 3: With ASR, ESP body protection, ice and snow on the road open casually
When a car starts on ice and snow, it tends to slip. ASR driving anti-skid system and TCS traction control system can reduce the driving force by reducing the throttle or commanding the gear box to downshift and brake skid wheels in order to ensure the smooth start of the vehicle. Electronic Stablity Program (also known as VSA, DSC for some models) not only controls the drive wheels but also controls the driven wheels. And by braking any one of the four wheels, the vehicle can maintain the trajectory consistent with the intention of the driver, prevent oversteering and understeer, and avoid danger. However, it should be noted that although the ESP can control four wheels, it cannot control the friction between the tire and the ground, so the ESP cannot exceed the adhesion limit control vehicle.
No matter how advanced the vehicle is, driving on an icy road still requires care.
