Hybrid vehicle energy recovery systems may be used to recover energy when the vehicle is braked or coasted and to use the recovered energy to recharge the power cells. On the one hand, the vehicle energy recovery can reduce the friction of the vehicle, and on the other hand, the vehicle energy recovery is beneficial to improving the utilization efficiency of energy sources. When the hybrid vehicle is in the energy recovery mode, the motor is used as a generator, the energy recovered during braking or coasting is used to generate electricity for the generator, and the electricity generated by the generation is converted by the inverter and used to charge the power battery of the hybrid vehicle.
The present embodiment relates to a control method employing a human-machine interface (HMI) for controlling and operating a hybrid vehicle energy recovery system. As shown in fig. 4, the hybrid vehicle energy recovery control system of the present embodiment includes an energy recovery unit, a power battery unit, a Vehicle Control Unit (VCU), and a human-machine interface (HMI). The energy recovery unit comprises a braking energy recovery module and a sliding energy recovery module. The energy recovery unit may charge the power battery during recovery of braking energy or slip energy. The whole vehicle controller can start or exit the energy recovery mode, and the recovery torque of the energy recovery unit is controlled according to the instruction input by the HMI. In the embodiment of the invention, the whole vehicle controller is used for receiving the command input by the HMI, and also can be used for receiving a pedal signal, a speed signal, a temperature signal and the like to judge whether the vehicle is in the energy recovery mode. The vehicle control unit also receives signals from the power battery unit. And the power battery unit sends signals such as a charging state, a temperature, a charging and discharging rate, error information and the like to the whole vehicle controller. The human-machine interface (HMI) sends instructions to the vehicle control unit by means of an electrical interface such as a communication network or a CAN bus. Naturally, in order to prevent the vehicle from being erroneously operated in a state such as acceleration, it may be provided that the energy recovery unit is disabled in a specific mode, and even if the HMI is started to control the energy recovery, the operation is disabled, for example, the operation interface may be in a gray state, and the energy recovery unit cannot be started by triggering the control interface menu of the HMI.
Specifically, the hybrid vehicle energy recovery control system of the embodiment includes an energy recovery unit, a power battery unit, a vehicle controller, and a human-machine interface. The energy recovery unit comprises a braking energy recovery module and a sliding energy recovery module; the power battery unit comprises a power battery and a battery management system, the battery management system charges the power battery unit according to the electric power provided by the energy recovery unit, and the battery management system also collects signals comprising charging states, temperatures, charging and discharging rates and error information; the whole vehicle controller is used for starting or exiting the energy recovery mode and controlling the recovery torque of the energy recovery unit according to an instruction input by the HMI; the whole vehicle control is used for receiving information comprising pedal signals and speed signals to judge whether the vehicle is in a state of prohibiting energy recovery, and the whole vehicle control also receives signals of a power battery unit to judge whether the power battery unit is in a state of being chargeable; the man-machine interface is used for sending an energy recovery control instruction to the whole vehicle controller.
The method for controlling the energy recovery of the hybrid vehicle based on the HMI comprises the following steps:
(1) Transmitting an energy recovery control request signal to the whole vehicle controller through a man-machine interface;
(2) The whole vehicle controller judges whether the vehicle is in a state of disabling the energy recovery unit according to the received information comprising the pedal signal and the speed signal, and if the vehicle is in the state of disabling the energy recovery unit, the whole vehicle controller sends a state that energy recovery control is invalid to the human-computer interface; if the energy recovery unit is not in a disabled state, a charging request confirmation signal is sent to the power battery unit, and if the power battery unit sends a signal confirming that the energy recovery unit can be charged to the whole vehicle controller, the whole vehicle controller wakes up the energy recovery unit to recover energy, and the energy recovery unit charges a power battery of the power battery unit;
(3) The control signal of increasing or decreasing the braking energy recovery intensity is sent to the whole vehicle controller through the man-machine interface, or the control signal of increasing or decreasing the braking energy recovery intensity is sent to the whole vehicle controller; and the whole vehicle controller controls the increase or decrease of the braking energy recovery intensity of the braking energy recovery module or controls the sliding energy recovery intensity of the sliding energy recovery module according to the control signal sent by the man-machine interface.
The operation of the man-machine interface is briefly described as follows: triggering an energy recovery adjusting button of the HMI interface, directly entering a menu shown in fig. 5, double-clicking an energy recovery control frame, expanding two options of braking and sliding, and clicking one option according to the actual situation, so that the menu interface shown in fig. 6 or 7 is displayed. Taking fig. 6 as an example, the abscissa is the sliding energy recovery intensity, the ordinate is the sliding distance, when the sliding energy recovery intensity is increased by clicking, the dot in the figure moves along the increasing direction of the abscissa, and when the button is decreased, the confirmation piece is clicked to start to work after the adjustment, otherwise, the last state is still maintained. Taking fig. 7 as an example, the abscissa is the braking energy recovery intensity, the ordinate is the braking distance, when the braking energy recovery intensity is increased by clicking, the dot in the figure moves along the increasing direction of the abscissa, and when the button is decreased, the confirmation piece is required to be clicked to start to work after the adjustment, otherwise, the last state is still maintained.
