When does ESP close?
ESP produced by different manufacturers has different names. Because the word ESP has become a registered patent of Bosch, similar systems of other manufacturers can only be renamed, such as Honda VSA, Toyota VSC, Nissan VDC and BMW DSC. However, I don't think ESP is a real theoretical name. The real scientific name should be ESC (Electronic Stability Control), but it is a habit for friends to call ESP. I'd better use ESP here.
The working principle of electrostatic precipitator is briefly described. ESP is a high-order function based on ABS anti-lock braking and ASR traction control system. It can judge the driving situation of the car through the state of the sensor, intervene the power of the engine, and brake one or more wheels separately at the same time to maintain the stability of the driving situation and the controllability of the car direction.
For example, when the car turns left or oversteer (the sensor feels too anxious when turning the tail on the right side), it will quickly brake the right front wheel to restore adhesion and generate reverse torque to keep the car in the original lane.
The function of ESP is to ensure active safety and keep the direction and tracking of vehicles within the controllable range.
Therefore, for ordinary drivers, ESP can help drivers improve the active safety factor and ensure that the car will not get out of control when it is in emergency avoidance or when the road is slippery.
However, ESP can't improve the physical limit of cars! ! !
Important things need three exclamation points. ESP can improve the active safety factor so that it won't get out of control, because most ordinary drivers' driving skills can't bring the active safety factor of the car to the real limit, and many wrong operations will lower the control limit, so ESP only ensures that the control of the car is not affected by these relationships and helps drivers keep the car within the dynamic limit. For people who can really drive, the driving limit can be higher than ESP, but believe me, you are not that kind of technical person, and neither am I.
Thirdly, ESP can't improve the physical limits of automobiles. You don't need to run wild with ESP. There is basically no system to save you when the speed exceeds the tire grip. I can only pray that the 120 system will save you.
So ESP is a good way for ordinary people to travel safely at home. Personally, I also advocate choosing a car with ESP.
But many cars basically have ESP system switches designed separately. If ESP is so good, why should someone turn it off?
In some special cases, the working principle of ESP to prevent wheel slip will not help, such as:
1。 When the car is stuck in the mud or off-road.
When trucks and other off-road situations occur, moderate car sideslip is needed to solve the problem, get rid of the predicament and climb the slope. At this time, it is helpful that ESP does not allow wheels to slip, so it is best to turn off ESP when encountering extreme off-road and trucks.
2。 When driving hard or wagging your tail and drifting.
As I said just now, the main driver needs to grasp the vehicle handling limit better than ESP, so most cars are not equipped with ESP. At the same time, the principle that ESP doesn't let the wheels slip at all is discussed with drift theory. Therefore, if you want to drive violently for excitement or drift, you still need to turn off ESP. But please remember: please go to a professional venue for intense driving and drifting, not racing on the highway! ! ! The most important-three exclamation points.
3。 When automobile tires are equipped with snow chains
Snow chain will interfere with the data of some sensors in ESP system due to the change of wheel diameter, resulting in inaccurate signals and affecting the normal work of ESP system. ESP may constantly intervene or report fault codes, so it is best to turn it off.
In addition, it should be noted that the integration of in-vehicle function adjustment is the general trend at present, and the ESP adjustment switch of many vehicles is not set separately, but integrated into the driving computer for operation. However, there is also a trend at present, that is, the car navigation integrated machine is modified later. Due to poor consideration, some all-in-one machines will lose the adjustment function of some driving computers after modification, including high ESP switch. If there is something wrong with ESP and it needs to be reset or really turned off, there will be a lot of trouble without this switch.
Well, what do you think of riders today? The esp editor who briefly introduced getting on and off the bus said so much. I don't know if my friends have a deeper understanding of how to get on and off the esp after listening to the brief introduction of the car editor. I hope the profile of Bianxiao Automobile can help my friend. If you want to know more, pay attention to this website. Bian Xiao's car is waiting for you here!
