How to solve the failure of BYD s7esp system (what is the failure when BYD s7svs lights up)
BYD s7ESP fault light is on, and the button doesn't work. Check the lower arm. It is estimated that the front and rear wheels are not in a straight line due to the deformation of the lower arm, so as to start ESP, or stop the brake to see if the brake light is on. If not, it means that the brake pedal sensor switch is broken, so change it.
The full name of ESP is ElectronicStabilityProgram, which is what we often call body stability control system. ESP is mainly used to deal with the risk of out-of-control tail flick caused by continuous turning as an emergency obstacle. In case of emergency avoidance, ESP intervenes to increase the driving wheel power; When there is a trend of tail flick, ESP will brake the other wheel and weaken the rotation, thus helping the vehicle to follow the driver's steering intention.
There are several main reasons why the esp fault light is on:
1. The combustion state is not good (the main reason why the engine fault light is on);
2. Engine knocking; Internal reasons (poor fuel quality; The inside of the engine cylinder is not clean, and there is carbon deposit).
3. This research consists of 3 parts. NHTSA also shows that the standard configuration of ESP can effectively reduce 34% car accidents, 765,438+0% car rollover accidents and even 59% SUV accidents.
How to solve the failure of BYD s7esp system (why BYD s7esp light is on)
There are many factors that lead to the failure of BYD ESP system, but the most common one in real life is the failure of wheel speed sensor. The wheel speed sensor obtains the wheel speed value through induction and feeds it back to the driving computer. Each wheel has an independent wheel speed sensor, and the anti-lock braking system and the electronic stability program system rely heavily on the wheel speed signal.
Electronic body stability system, ESP for short, is a patent of Bosch Company. ESP system is actually a traction control system. Compared with other traction control systems, ESP can control not only the driving wheel but also the driven wheel. For example, a rear-wheel drive car often turns too much, and the rear wheel is out of control. ESP will slow down the outer front wheel to stabilize the car; When the steering is too little, ESP will slow down the inner and rear wheels to correct the tracking direction, thus correcting the driving direction.
ABS and ESP are two systems that directly interfere with braking, and any improper braking operation of moving vehicles will bring serious consequences. Therefore, after any wheel speed signal is lost, both systems will report faults and all systems will go on strike. At this time, the vehicle can still run normally, but ABS and ESP cannot be used. The use of wheel speed sensor determines that its working environment is not very good. We drive and wash cars in the water every day, which may lead to water in the plug and affect the normal work of the sensor. When we find that the ESP light is on during driving, we need to slow down the driving speed, avoid excessive steering, and quickly find a nearby repair shop for maintenance.
