How to Prevent Stalling During Hill Start in Driving Test?

[LeLeah]

Edge slope must be given throttle. During training, you may often encounter situations where you can climb without turning off the engine or giving throttle, but you cannot take such risks during the test. The reason why you can start smoothly without throttle is that the "idle speed" of this training car is higher than other cars. Idle speed is the minimum speed at which the engine maintains operation without doing work. When you are on a slope, if you don't give throttle, it is very likely that the vehicle will stall due to insufficient idle speed and fail to start the vehicle on the slope. Once the vehicle rolls back, the engine becomes even harder to stop. When there is a rollback, you can only step on the brake and clutch first, stop, and then start again. Control the clutch. Don't lift the clutch too high. If you don't release the brake, it will stall. Just lift the front of the car. You don't have to reach the "perfect contact point." Because when throttle is given, even if the contact point is not fully lifted, the car won't slip when the brake is released, and the car will remain stationary. In this case, don't panic when looking at the car, thinking the clutch isn't lifted enough. In fact, at this time, since there is no rollback, it means the clutch is already semi-engaged, and you can slightly lift the clutch with throttle. Of course, if you can control the clutch contact point well (the front of the car is obviously lifted, and the body does not shake before the engine shuts off), it's best to add throttle, release the handbrake, and move the car at this time. Considering that the foot brake and handbrake serve the same purpose, during practice, if you stop on a slope without a handbrake, when starting again, the coordination between the foot brake and clutch is the same—keep the right foot stepping on the brake, lift the left foot to the clutch contact point, then keep the left foot still, and immediately step on the throttle with the right foot when leaving the foot brake. However, this can be used in practice to train the coordination of throttle and clutch. During the test, no matter the situation, as long as you stop on a slope, you must pull the handbrake and shift to neutral. Throttle and clutch coordination refers to the operation sequence: throttle first, then clutch. The throttle has no travel, while the clutch has travel. The so-called travel refers to the process from the implementation of the action to the effect of the action. When braking, brake first, then release. During the test, step on the clutch first and coast in neutral. After stepping on the brake to a certain extent, the body will shake, which means that due to the resistance of the brake, the engine has started working with an immovable gear. At this time, you need to step on the clutch to cut off the engine's power transmission to avoid stalling.
