A control assembly for an electric automobile comprises a driving motor controller, and the driving motor controller comprises a plurality of rectification inverter circuits which are connected in parallel. According to the control assembly for the electric automobile, a rectification inverter circuit in an existing generator controller is connected with the rectification inverter circuits in thedriving motor controller in parallel; the generator controller is not removed, and a corresponding circuit of an original generator controller and a rectification inverter circuit in an original driving motor controller are used for jointly forming a new rectification inverter circuit used for being connected with a driving motor.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a control assembly for electric vehicles. Background technique [0002] The control assembly for electric vehicles mainly includes: generator controller, drive motor controller, steering oil pump motor controller, air pump motor controller and other equipment controllers. Through these controllers, the control assembly can realize functions such as controlling the vehicle's driving, braking, steering, opening and closing of doors, and energy recovery. [0003] The structure of the existing control assembly for electric vehicles is usually as follows figure 1 shown. The first inverter module 101 is connected to the air pump motor M1 to drive the air pump motor M1 to run; the second inverter module 102 is connected to the oil pump motor M2 to drive the oil pump motor M2 to run. The drive motor controller 103 is used to convert the received DC power into AC power to dri...
