Example Embodiment

[0037] Such as figure 1 As shown, the electric drive anti-slip protection control method of the entire vehicle TCS operating condition is included, including the components of the vehicle including the vehicle data acquisition module, the TCS function enable module, the electric drive slip-torsion control module, the sliding limit torque mark Clear module; the vehicle data acquisition module mainly collects the speed, speed and other signals to the TCS function enable module by the CAN bus, and the TCS enable module determines whether the current working condition needs TCS function intervention after data processing, and Output its functional validity marker; the electric drive system sliding limit twigmatism block is restricted to the torque according to the TCS, and the restricted torque is output in time and determines the restricted torque by the restricted sign bit; The slide limit twisted sign bit cleaning module is mainly cleared according to the current motor speed change...

Abstract

The invention discloses an electric drive anti-slip protection control method based on a whole vehicle TCS working condition, and the method comprises the steps: a whole vehicle data collection module collects the speed and rotating speed data information of a whole vehicle, and transmits the information to a TCS function enabling module and an electric drive slip torque limiting control module through a CAN bus; the TCS function enabling module judges whether a current working condition needs TCS function intervention or not according to the whole vehicle data information; and the electric drive slip torque limiting control module judges whether the electric drive system intervenes in torque limiting adjustment or not according to the TCS enable signal, and when the TCS function is enabled, the torque limiting protection strategy of the electric drive system intervenes in torque adjustment. The torque is actively adjusted through electric driving in cooperation with the TCS working condition, the driving comfort under the slipping working condition is guaranteed, the torque can be rapidly and effectively adjusted according to the actual slipping working condition, the electric driving system is protected in time, and the phenomenon that due to the too large rotating speed change rate, the electric driving system overflows is prevented.

Description

technical field [0001] The invention relates to the field of electric drive anti-skid protection, in particular to an electric drive anti-skid protection control method based on the TCS working condition of the whole vehicle. Background technique [0002] With the continuous breakthrough and innovation of new energy vehicle technology, more and more are becoming mature and popular among the public, and have been recognized by users and society, and their installed capacity is increasing year by year. New energy vehicles are focused on by users in terms of driving comfort, safety, and economy. [0003] When pure electric new energy vehicles are running on normal roads, the driving force of the vehicle is not only related to the output torque of the electric drive system and the reduction ratio of the reducer, but also has a great relationship with the ground adhesion; when the ground adhesion is large enough, the electric The output torque of the drive system can be utilized...
