AI Technical Summary
When existing hybrid vehicles switch from parallel mode to series mode, the engine speed increases, resulting in significant noise and affecting the user experience.
When the environmental conditions during vehicle operation reach the critical conditions for switching between series and parallel modes, the vehicle obtains slope parameters and acceleration or pedal opening change parameters to determine whether the preset threshold is met. If the threshold is met, the vehicle maintains parallel mode driving for the set duration to avoid directly switching to series mode and thus avoids issues such as increased engine speed and noise.
By delaying the switch to series mode, noise during engine operation is avoided, thus improving the user experience.
