A semi-automatic transmission (SAT) (also known as a clutchless manual transmission, automated manual transmission, flappy-paddle gearbox, or paddle-shift gearbox) is an automobile transmission that does not change gears automatically, but rather facilitates manual gear changes by dispensing with the need to press a clutch pedal at the same time as changing gears.
It uses electronic sensors, pneumatics, processors and actuators to execute gear shifts on input from the driver or by a computer. This removes the need for a clutch pedal which the driver otherwise needs to depress before making a gear change, since the clutch itself is actuated by electronic equipment which can synchronise the timing and torque required to make quick, smooth gear shifts.
The system was designed by automobile manufacturers to provide a better driving experience through fast overtaking maneuvers on highways. With Pinalloy Paddle Shifter Extensions, you could use a system with a conventional gearchange but without the need for manual clutch operation.
How would you do if there was a visible sized stone in your lane at the high way?
When driving, it is inevitable that you will encounter various unexpected situations, especially at the high way. If you were not react properly, you would be in danger position. For example, a visible sized stone in your lane, would you immediately brakes or switch lane to avoid it?
Some people would prefer immediately braked and switch line to avoid it. However, this is quit a high risk if the speed is too fast, and it may cause an uncontrolled accident and lead to a rollover. It is better to slow down first, turn on the Hazard Warning Lights and then choose the appropriate method.
If the stone on the road is relatively small, we can roughly judge whether there is any influence on the chassis of the car. In general, the chassis height of the family cars are usually 12cm-20cm, and the chassis height of the SUV is larger/better than family cars in such situation. It can reach 30cm, as long as it does not exceed the gap of the car chassis and off the ground, you can directly pass through. If the height of the stone and the chassis is about the same or lower than the height of the chassis, you can drive over the stone to avoid sudden braking or changing lane.
However, if the stone is relatively large, it is necessary to quickly observe the road situation and see if it is possible to change lanes. If it is impossible to change lanes, calm down, turn on the Hazard Warning Lights, slow down your vehicle and hold your steering wheel tightly. Try not to let the vehicle run out of control, and observe the road situation to avoid collision and minimize the risk. Do not panic, and don't let the car get out of control.
