Embodiment 1
[0034] Such as figure 1 Shown is a schematic flow chart of a method for controlling the energy recovery intensity of an electric vehicle coasting provided by an embodiment of the present invention. figure 1 The method shown includes the following steps:
[0035] S101: Real-time monitoring of accelerator pedal opening and vehicle speed information while the vehicle is running;
[0036] S102: If the accelerator pedal opening is lower than the accelerator pedal opening threshold A%, and the vehicle speed is greater than or equal to the minimum coasting energy recovery speed u1, enter the coasting energy recovery stage;
[0037] S103: Detect the distance between the current vehicle and the vehicle in front, and obtain the deceleration a2 required for braking the current vehicle based on the distance;
[0038] S104: If the deceleration a2 is greater than the preset deceleration threshold a1 and is less than or equal to the maximum deceleration a_max allowed for coasting energy re...
Embodiment 2
[0057] Such as Figure 5 Shown is a schematic structural diagram of a device provided by an embodiment of the present invention, including:
[0058] A monitoring unit 501, configured to monitor the accelerator pedal opening and vehicle speed information in real time while the vehicle is running;
[0059] The first judgment execution unit 502 is used to enter the coasting energy recovery stage when the accelerator pedal opening is lower than the accelerator pedal opening threshold and the vehicle speed is greater than or equal to the minimum coasting energy recovery vehicle speed;
[0060] The deceleration acquisition unit 503 is used to detect the distance between the current vehicle and the vehicle in front, and acquire the deceleration required for braking the current vehicle based on the distance;
[0061] The second judgment execution unit 504 is configured to adjust the coasting energy recovery demand torque when the deceleration is greater than the preset deceleration t...
Embodiment 3
[0064] The present application also provides a computer-readable storage medium, such as flash memory, hard disk, multimedia card, card-type memory (for example, SD or DX memory, etc.), random access memory (RAM), static random access memory (SRAM), read-only Memory (ROM), Electrically Erasable Programmable Read-Only Memory (EEPROM), Programmable Read-Only Memory (PROM), Magnetic Storage, Magnetic Disk, Optical Disk, Server, App Store, etc., on which computer programs, program When executed by the processor, the electric vehicle coasting energy recovery intensity control method in the method embodiment is realized.
