Tesla has brakes. Why do many people hate its single pedal mode？

Not long ago, Tesla crashed into the tank 300. Although it was finally characterized as "misoperation", it still caused many people to vomit about Tesla’s single pedal mode. But in fact, Tesla’s models still have brake pedals, and the "single pedal mode" that many people on the Internet spit out is actually a spit on Tesla’s "kinetic energy recovery technology", or more specifically, a spit on Tesla’s cancellation of the "kinetic energy recovery mode strength adjustment function".

What is the single pedal mode?

From the clutch, brake and throttle of manual transmission to the brake and throttle of automatic transmission, and then to the new energy vehicle, the car can be controlled only by the switch. In the propaganda of some new energy vehicle manufacturers, we can see such things: the single pedal mode not only changes the driving mode of the owners, but also changes the sense of anxiety and leg fatigue when driving in urban congestion.

The single pedal mode was originally a technology used in racing cars. As the name implies, the acceleration and braking operations of vehicles were completed by one accelerator pedal. Of course, the single pedal mode of a normal private car actually has two pedals, one accelerator and one brake. Step on the accelerator to accelerate, release the accelerator to slow down, and use a pedal to realize the functions of acceleration and deceleration. In the new energy vehicle, the single pedal mode represents the kinetic energy recovery technology, which recovers energy by loosening the throttle and then carries out a reverse charging.

Advantages and disadvantages of kinetic energy recovery

Kinetic energy recovery technology can effectively extend the battery life and increase the cruising range of new energy vehicles, at the same time, it can also reduce the fatigue of the owner’s leg and relax the other foot. But from another point of view, the change of driving habits brought about by the simplification of driving mode also has great security risks.

Different from the three-pedal driving mode of manual transmission to the two-pedal driving mode of automatic transmission, although the clutch pedal operation is missing, the acceleration and braking operations are still independently operated, while the single-pedal mode, although the brake pedal is still effective, gives priority to encouraging the owner to rely on the accelerator pedal to complete the acceleration and braking operation. In the single pedal mode, only sudden braking requires stepping on the accelerator, while the rest of the deceleration is completed by loosening the accelerator, and the strength depends on "habit". In case of an emergency, it is easy for some car owners to make mistakes. Should we use a loose pedal or a brake to slow down?

Fortunately, the single pedal mode of most private cars can decide whether to use the kinetic energy recovery function by adjusting the deceleration of the throttle. At one time, many Tesla owners adjusted the deceleration of the single pedal mode to the minimum to get the experience equivalent to the double pedal. Similarly, the kinetic energy recovery function in this mode is basically equal to nothing.

What is Tesla’s problem?

Tesla’s problem is that it cancels the "adjustment of kinetic energy recovery", which is equivalent to directly depriving users of their right to choose, so that all Tesla owners can only use "high kinetic energy recovery", that is, mandatory single pedal mode. Although the brakes are still there, not all Tesla owners like the driving experience of single pedal mode.

summary

Tesla’s cancellation of the dynamic adjustment function of "kinetic energy recovery" is obviously not good for the owner. It not only cancels the option of new owners, but also makes new owners get used to the single pedal mode, which increases the learning cost and the risk of misoperation, and also reduces the driving experience. The so-called relieving leg fatigue in single pedal mode has no practical significance, because as long as there is a brake pedal, your left foot can’t leave the brake pedal. Since the posture will not change, how can you relieve leg fatigue?

But for Tesla, there are many benefits to canceling this function. That is, it cultivates users’ habits and increases the learning cost for users to choose other brands; It can also reduce the CRBS function. After the compulsory kinetic energy recovery, the battery life of Tesla models will also be enhanced, which can be said to be harmless. Many people think that this is a reason for Tesla to cancel the dashboard, which is entirely based on cost saving, not on consumer experience, just like Apple’s mobile phone cancels the charger for environmental protection.
