    摘要: A method and device for controlling a DCDC converter, used for a hybrid electric vehicle and relating to the technical field of vehicle control. The method comprises: according to an output end current limit value and an actual voltage value, acquiring a first preset value corresponding to an input end power; according to the maximum discharge power of a high-voltage battery and the actual discharge power of an electric motor, acquiring a second preset value corresponding to the input end power; and determining the minimum value in the first preset value and the second preset value as an input end target power limit value. Multiple combination working conditions of sufficient or insufficient power sources at the input end are considered.

    摘要: The present disclosure relates to the field of vehicle technology and provides an energy recovery control method, a system, and a vehicle. The method is applied in a vehicle, and the vehicle comprises a drive motor and a battery electrically connected to the drive motor; a first energy recovery torque curve with respect to the drive motor is pre-configured in the vehicle, and the first energy recovery torque curve is used to indicate a correspondence relationship between vehicle speed and energy recovery torque of the drive motor. The present disclosure performs reduction on a first energy recovery torque curve by means of utilizing a reduction ratio, allowing energy recovery in accordance with a relatively low torque strength when a usable charge power of the battery is unable to satisfy a preset power requirement corresponding to the first energy recovery torque curve.

    摘要: Provided are a method and a device for timing a scheduled charging, and a terminal device. The method for timing a scheduled charging comprises steps of: acquiring, in response to a condition that a charging gun is connected, a scheduled-charging start time for equipment and a first current-absolute-time at which a connection of the charging gun is completed; determining a first time duration to the scheduled-charging start time according to the scheduled-charging start time and the first current-absolute-time; performing a compensation on the first time duration to obtain a second time duration, and starting a timing; and terminating the timing, when the second time duration is reached, and waking up the equipment.

    摘要: A method for torque control of an electric vehicle on a slippery road surface and a terminal device are provided. The method includes: presetting a torque-lower-limit-value; setting, when an anti-lock braking system of the electric vehicle is activated, the torque-lower-limit-value as a second numerical value to reduce an absolute value of a reverse torque exerted on the vehicle wheel due to the energy recovery, and the vehicle wheel enters an anti-lock state; maintaining the anti-lock state of the vehicle wheel for a preset first time period; comparing the currently requested torque value with a preset third numerical value after the first time period is passed; and resetting the torque-lower-limit-value to the first numerical value to enable the vehicle wheel to exit the anti-lock state, if the currently requested torque value is greater than the third numerical state.
