Embodiment Construction

[0042] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Several embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

[0043] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

[0044] Unless otherwise def...

Abstract

The present invention provides an energy recovery method and system. The method includes: when the current vehicle speed is higher than the threshold and the throttle opening is zero, the vehicle controller sets the coasting energy recovery torque corresponding to the current vehicle speed to the motor; the vehicle control The controller detects whether the brake pedal is depressed; if so, the vehicle controller calculates the maximum energy recovery torque that the motor can provide after the coasting energy recovery torque is removed according to the current vehicle parameters, and sends the maximum energy recovery torque to the brake control The brake controller calculates the braking energy recovery torque based on the maximum energy recovery torque and the current vehicle slip rate and sends it to the vehicle controller; on the basis of the coasting energy recovery torque, the vehicle controller recovers the braking energy Torque superposition set to the motor. In the method of the present invention, by proposing a coasting+braking energy recovery strategy dominated by the vehicle controller, the energy recovery capability of the motor can be brought into full play to achieve the optimal energy recovery effect.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an energy recovery method and system. Background technique [0002] Among new energy vehicles, especially pure electric vehicles, energy recovery has become a basic vehicle function that cannot be ignored. The function of the energy recovery function is to convert a part of the mechanical energy when the vehicle is decelerating or braking into electrical energy through the motor under the premise of ensuring the driving stability of the electric vehicle, and the recovered electrical energy is stored in the battery pack. [0003] Among the existing technologies, due to technical bottlenecks, most new energy vehicles use the Regeneration Brake System (regenerative braking system function, RBS) in the ESP (Electronic Stability Program, vehicle body electronic stability system) to coast or brake the motor. Energy recovery control, but ESP cannot monitor the status of the...
