  • Publication number: 20230303055
    Abstract: The present disclosure relates to a method for a torque control of a hybrid vehicle, a storage medium and an electronic device. The method includes: determining a target-total-torque-change-gradient when a limitation requirement for a gradient of torque change of a DCT is received; determining a torque request of an electric motor and an actual-torque-response-change-gradient of an engine; and determining a gradient of torque change of the electric motor according to the target-total-torque-change-gradient and the actual-torque-response-change-gradient of the engine; and filtering the torque request of the electric motor according to the gradient of torque change of the electric motor. The limitation of the gradient of torque change of the DCT is considered, A problem that the actual total torque responses of the electric motor and the engine exceeds the limitation requirement of the gradient of torque change of the DCT is effectively solved, and a drivability of the whole vehicle is improved.

  • Publication number: 20230219552
    Abstract: A method for controlling an interference torque for a vehicle is provided. The method is applied to a new energy vehicle including an electric motor and an engine, and includes steps of: arbitrating between a pedal torque of a driver and an interference torque required by ESP; performing an initial allocation on the electric motor and/or the engine in response to the pedal torque when the vehicle is in a hybrid drive mode, to meet an engine torque request while ensuring that the engine is operated at an optimal operation point; and determining, based on the initial allocation, whether the motor is capable of fully responding to the arbitrated torque, if so, controlling the motor to respond to the arbitrated torque in priority, otherwise controlling the engine and the motor to cooperatively respond to the arbitrated torque.

  • Publication number: 20230043607
    Abstract: A turbo lag boost compensation method is provided, including: calculate a theoretically required boost torque Ts; compare the theoretically required boost torque Ts with the maximum output torque Tpmax of a P2 motor; when Ts?Tpmax, a required output boost torque Ts? is equal to Tpmax; when Ts<Tpmax, the required output boost torque Ts? is equal to Ts; determine whether a turbo lag boost timing is activated; if yes, output the required output boost torque Ts?; and if not, the boost torque is zero. Also provided are a turbo lag boost compensation apparatus, a turbo lag boost compensation device, a hybrid power vehicle, and a storage medium. The present invention effectively solves adverse effects such as a slow torque response and a sudden torque change caused by a turbo lag on an entire vehicle, and improves the drivability and power of the entire vehicle.
