What is the automatic D gear of the scooter after going uphill?
So far, we haven't seen the phenomenon of automatic transmission vehicles slipping after going uphill, only experienced the phenomenon that automatic transmission vehicles began to slip on the ramp. Automatic cars have strong climbing ability. Even small cars like VIOS, Jetta and Na Yue can climb 33% when fully loaded. If the owner D slides uphill and slightly steps on the accelerator, the vehicle will definitely move forward with surging power. However, automatic startup and scrolling are common.
Automatically stop the vehicle ramp and start rolling? This illustrates a problem. The development process of this car is unqualified and needs to be rebuilt. One of the standards of vehicle development is that vehicles are not allowed to slip when starting on a ramp. After all, it is very dangerous for car owners to start from the ramp and sneak back.
Vehicle skidding due to insufficient braking force. In order to suppress the phenomenon of skidding when starting on a ramp, the current vehicles have developed an automatic holding function and an auxiliary function for starting on a ramp. These functions are combined with the braking system of the vehicle. The braking system will judge the braking force required by the vehicle according to the slope of the road. When the owner does not step on the brakes, the braking system will also apply braking force according to the predetermined strength to prevent the car from slipping. After the owner steps on the accelerator, the braking force will be automatically eliminated.
In order to prevent the vehicle from slipping on the ramp, the time point of eliminating the braking force must be strictly controlled. Only when the output torque of the engine is transmitted to the wheels, and the driving force of the wheels is greater than the downward resistance of the vehicle along the ramp, can the braking force be eliminated. In this case, the vehicle will not slip.
Analysis on the causes of vehicle skidding when starting on the ramp: However, it is not excluded that there are some vehicles specially supplied by China, or vehicles that can reduce costs and increase efficiency. The vehicle itself has no ramp start assist function or automatic holding function. It is inevitable that this kind of vehicle will slip when driving on a slope. The main reason is that the braking force instantly becomes zero after the owner releases the brake. At this time, the owner stepped on the accelerator, the engine speed increased, and the engine torque could not be transmitted to the gearbox immediately. After all, the gear combination of the gearbox takes time, that is to say, the instantaneous driving force of the vehicle tire is very small, which is less than the resistance of the vehicle descending along the ramp. At this time, the automatic vehicle will slip.
This vehicle slip phenomenon has little to do with the gear (L/S gear), which is a normal phenomenon and cannot be solved by shifting gears.
How does the owner solve the problem of starting the car?
The car is dead and people are still alive. Car owners can give full play to their intelligence and drive cars according to their own experience, which can curb the phenomenon of car skidding. As we all know, both Autohold and ramp start assist use the braking system to control the vehicle to slide on the ramp, and the owner can start with the help of the hand brake system. When the owner drives the vehicle in D gear, he first steps on the accelerator, and the engine speed rises, and the engine torque is transmitted to the wheels through the gearbox. When the vehicle tends to drive upward, the owner releases the handbrake and the vehicle will immediately move forward without slipping.
It is no longer a patent for manual transmission vehicles to slip when starting on a ramp. With the saving of vehicle cost, many automatic cars will slip now. Car owners must carefully check their cars to see if there are similar problems to prevent traffic accidents.
What does automatic eco mean?
As an energy-saving mode of eco-car, friends can make reasonable choices according to road conditions during driving. Most eco-energy-saving modes are quite suitable for urban roads and can save fuel consumption for small partners. If the eco energy-saving mode will reduce the response rate of the output, then you will feel that the power of the car is weak, and it is not recommended to use eco mode when the car is driving at high speed.
Attachment: automatic gearbox fuel saving skills:
1. Start slowly:
When starting automatically, the engine speed is high, so it is necessary to adjust the throttle of the car without sudden acceleration. After stepping on the accelerator deeply, the fuel supply is excessive and the fuel consumption of the car increases. When starting, step on the accelerator slowly to achieve steady acceleration.
2. Less braking:
When the car is driving, you should use the brakes as little as possible. Frequent brake start-up will easily increase the fuel consumption of the car, and will also cause the wear of the brake pads of the car. When passing the traffic lights, adjust the speed by changing the traffic lights, and judge whether to accelerate or decelerate in advance.
3. Prevent violent refueling:
Many small partners pursue speed when driving, and there is often a phenomenon of fierce refueling. Although there will be a feeling of pushing back when refueling hard, the fuel consumption of the car will increase and the working intensity of the engine will increase.
4. Prevent frequent lane changes:
Cars that often change lanes are often seen in the usual driving process. In the process of frequent lane changes, the car should accelerate and the fuel consumption should increase accordingly. What's the significance of automatic eco for D-block cars after going uphill @20 19
