Recently, I saw a lot of BYD Song plush dmi high-speed can not keep the electricity, which in turn led to the problem of vehicle stall, reflecting on the New Year's Day on the highway is estimated to be the legendary stall.
The stall case on the Internet, can not be said to be black car at a glance, there is a problem, it is also a fact, you do not have a problem, others have not been black, not to mention that I myself have encountered this so-called stall problem. Compared with the stall on the network, most of the speed is about 110 (the speed of the network big V analysis is maintained for a long time to maintain 130 will not be able to keep the electricity), after driving for a distance, the power can not be saved until about 15%, and then step on the accelerator and do not go, the speed is maintained at about 60, the difference is that my power is 40%, the accelerator does not go, the engine is loud.
New Year's Day high-speed, before departure power 50, mandatory power preservation 50 + Eco + Hev, when the vehicle traveled more than 100 kilometers, the altitude rose by more than 1000, the outdoor temperature dropped to about 6 °, the power fell to 40, suddenly found that stepping on the throttle is not how to go, the engine sound is loud, the speed drops, switch to intelligent power preservation, the power returns to normal, the engine sound is also small (at that time a little nervous, switching to intelligent power protection is good for a long time). Compared with the previous hot weather, the current power of high-speed forced power retention + hybrid + eco is normal, it may be that the 1.0 system OTA has been upgraded once (optimizing the map APP that time), and the control logic of the engine in the forced power retention mode may change. When I returned, it was always intelligent power retention 50 + hybrid + eco, and everything was normal.
Consult the technician of BYD Auto APP, universal mode: normal + hev + intelligent power preservation 50, high-speed, mountain road the best sport.
My stall may be the most special one in the whole network, one is that my power in 40% is to step on the accelerator and not go, the engine is loud, the speed of the car is reduced from more than 100 to more than 70, and the second is to force the power protection to convert into intelligent power protection. I hope it's just an occasional bug in the system, otherwise my heart is not good, and I can't convince the whole family to buy this car.
I hope that the great BYD company can optimize this system and treat our guinea pigs kindly. It is recommended to make the existing norm mode into a smart mode that is, a fool mode (according to the current power, altitude, speed, automatically match the soc value, whether it is mandatory to maintain power or intelligent power, whether to hybrid or Ev, whether to switch to sport), taking into account power and fuel economy, even if the fuel consumption is high. Those who have strong hands-on ability and like to study will manually match it by themselves, and lazy little whites like me like to press the accelerator and brake hard after the vehicle starts to make things happen.
Overall, the current driving of more than 7600 kilometers, feel that the car as a whole is good, regardless of power, fuel consumption (the city measured 6 points or more) or the space in the car, vehicle configuration can meet the demand, unfortunately the turning vehicle support is slightly insufficient, take the rugged kind of bad road, the amplitude of vehicle beating is larger, afraid of hitting the chassis, the handrail box cup slot can not put the teacup, the trunk is not large, the location of wireless charging can also be optimized.
![It has always been said that the engine is the heart of the car. In other words, the powertrain is the core of the car. In an era when the fuel engine/transmission was the core of the powertrain, this german brother was not only that[fig]](data:image/gif;base64,R0lGODlhAQABAIAAAP///wAAACwAAAAAAQABAAACAkQBADs=)
