Now it is snowing in many parts of the north, and some drivers feel that handcarts are safer than automatics when they run in the snow, why do they feel this way? Now let me analyze it with you. The first is the precision of the power control. From the structure of the machine and the principle of power transmission, when we drive a manual transmission car, it is indeed very easy to accurately control the output of this power, and when driving on snowy days, it will inevitably have a certain impact. For example, when we start, an intersection is just uphill, and the snow and snow will slip and hinder the passage of the entire vehicle, but if you are driving a manual car, it is easy to start on the snowy ramp. Because when manual transmission controls power, it must be more accurate than an automatic car.
So, while it's easy to use, he usually controls the powertrain through three main factors: the throttle and the clutch. For example, when you start at a speed, you can control the degree of linkage very well by gently stepping on the throttle and slowly separating the clutch. Deep into the throttle, we have the clutch. The manual does have a natural advantage over the automatic. On the other hand, in an automatic car, that is absolutely not OK. Because there is only one accelerator pedal, if we lightly pedal, the power of the whole car is gone. In addition, if you step very deeply, the snow will be very slippery. In addition, automatic transmission cars can only force a very small number of automatic transmission cars with 2-speed start, so they are not as flexible and accurate in terms of power control as manual cars. Second, the power control of engine braking is more accurate. In the snow we use good engine brakes. This in itself is a very good driving habit. Moreover, the engine brakes of the manual transmission are much clearer than those of the automatic transmission, so it is easy to control.
This is because the manual transmission is driven between the engine and the transmission using a clutch. Unless we step on the clutch, there is a completely hard linkage between them, but at this point the power of the engine depends on our accelerator pedal. During driving, as long as the engine speed is greater than a certain value, the engine is immediately shut down after releasing the throttle, and the braking force between the gears is also very clear. Choosing the right gear on a long downhill road allows you to control your speed all the way without having to brake. In contrast, for automatic transmission cars, a hydraulic variable resistor is used between their engine and the transmission. The hydraulic variable resistor has direct braking power to the engine, and the automatic transmission control computer also has certain engine control authority. At this point, you can enter a braking state.
It can be seen that it is not particularly controlled in actual operation. If manual mode is used, the brakes need to be slammed frequently according to the torque converter. Third, brake characteristics. When we are driving in the snow, if the manual gear is on the brakes, it is easy to feel the state of the entire wheel. In most cases of manual vehicles, stepping on the brakes will cause the drive wheels to have no power as a whole, so it is easy to appreciate the braking effect of the power when stepping on the brakes, and it is easy to judge the adhesion of the road surface. As a result, the accuracy of the braking distance is also greatly improved. Our automatic transmission cars use torque converters, so there's a smart connection between the engine and the transmission when braking. Moreover, the drive is still balanced by our engine. At this time, the feedback given by the brakes is very vague, and it is more difficult to feel the state of the entire wheel, which affects the correct judgment of the braking distance.
In summary, on snowy days, the reason why people feel that manual cars are safer than automatic cars is because manual cars give drivers room to operate. Especially for drivers with experienced driving, the safety of driving on snow has been improved to a certain extent, so in the face of such weather, especially in the northeast region, buying a manual car can get an advantage in snow.
