Embodiment 1
[0059] This embodiment provides a vehicle control method based on a BSG motor, which is used in an engine controller, such as figure 2 As shown, steps S101, S102 and S103 are included, and each step will be described in detail below.
[0060] In step S101, the current vehicle information collected in real time is received. The current vehicle information includes the current engine state, current gear position, current vehicle speed, current first battery level, current second battery level, current BSG motor mode, current accelerator pedal degrees, current brake pedal opening and current coolant temperature.
[0061] In step S102, a control strategy is determined according to current vehicle information, and a corresponding control signal is sent according to the control strategy.
[0062] In step S103, the current failure mode is judged according to the current vehicle information, the control strategy and the corresponding control signal, and a corresponding alarm indicat...
Embodiment 2
[0080] This embodiment provides a vehicle control method based on a BSG (Belt-driven Starter / Generator) motor, and the control method is used in an engine controller ECU (Engine Control Unit), such as image 3 As shown, steps S201, S202 and S203 are included, and each step will be described in detail below.
[0081] In step S201, the current vehicle information collected in real time is received. The current vehicle information includes the current gear position, current vehicle speed, current first battery level, current second battery level, current BSG motor mode, current accelerator pedal opening, current brake Pedal opening and current coolant temperature.
[0082] Among them, the current engine state is used to indicate whether the current engine is running or turned off. The first battery refers to the 12V lead-acid battery assembled in ordinary vehicles, and the second battery refers to the newly added 48V lithium-ion battery in the present invention. The current BSG ...
Embodiment 3
[0139] This embodiment provides a vehicle control device based on a BSG motor, the control device is used in the engine controller ECU, such as Figure 4 As shown, it includes an information collection module 301 , a policy determination module 302 and a fault judgment module 303 , and each step will be described in detail below.
[0140] The information collection module 301 is configured to receive the current vehicle information collected in real time. The current vehicle information includes the current gear position, the current vehicle speed, the current first battery level, the current second battery level, the current BSG motor mode, and the current accelerator pedal opening , the current brake pedal opening and the current coolant temperature;
[0141] Among them, the current engine state is used to indicate whether the current engine is running or turned off. The first battery refers to the 12V lead-acid battery assembled in ordinary vehicles, and the second battery ...
