Energy recovery torque control method and device and automobile

Abstract

The invention discloses an energy recovery torque control method and device and an automobile. The method comprises the steps that when the automobile is in an energy recovery working condition and it is detected that an automatic anti-lock braking system (ABS) or an automobile body stabilization system (ESP) is activated, the sum of the detection times that the ABS and the ESP are in the activated state in the current energy recovery stage is determined; and according to the sum of the detection times of the ABS and the ESP in the activated state, the energy recovery torque is controlled to be reduced. According to the scheme, when the automobile is in the energy recovery working condition and it is detected that the automatic anti-lock braking system (ABS) or the automobile body stabilization system (ESP) is activated, energy recovery is not directly forbidden or completely forbidden, the energy recovery torque is adjusted to be reduced according to the sum of the detected times that the ABS and the ESP are in the activated state; the interference between energy recovery and the ABS or the ESP is reduced or avoided, and the energy recovery rate is increased to the maximum extent while the safety of the whole automobile is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an energy recovery torque control method, device and automobile. Background technique [0002] Constrained by the battery capacity, the short driving range of pure electric vehicles has always been one of the issues that technical engineers and pure electric vehicle users are currently paying close attention to. [0003] Since the battery capacity cannot be expanded indefinitely, in order to maximize the driving range, it is necessary to maximize the use of energy and recover as much energy as possible. At the same time, as car users pay more and more attention to safety, ABS (Automatic Anti-lock Braking System) or ESP (Electronic Stability Program, body stability system) has gradually become the standard configuration of pure electric vehicles. . [0004] However, in the existing technology, the energy recovery torque will interfere with the application of ABS and ESP. Whe...
