Problems solved by technology

[0005] The existing one-to-two controller has the following disadvantages: 1. The controller is large in size, heavy in weight, and low in space utilization, which is not conducive to the layout and weight reduction of the whole vehicle; 2. The internal wiring harness of the controller is complicated in layout and weak in anti-interference ability. Low reliability, not easy to maintain

Abstract

The invention provides a vehicle one-driving-two axle drive controller, and belongs to the technical field of vehicle motor control. A one-driving-two axle drive controller in the prior art is large in size, heavy in weight and complex in internal wiring harness arrangement. The one-driving-two axle drive controller comprises a shell, a main control board, a signal adapter board, a first drive board, a second drive board, a radiator, a first full-bridge driver and a second full-bridge driver. An upper and lower cavity topological structure is adopted, two motor control modules share a water channel, space is effectively utilized, and the size and weight of the controller are reduced; the sampling signal adapter plate replaces a large number of wire harnesses, and is stable in performance and high in reliability.

Description

technical field [0001] The invention belongs to the technical field of motor control for vehicles, and in particular relates to a drive controller for one drive and two bridges. Background technique [0002] With the upgrading of the automobile energy industry and automobile control technology, electric vehicles have become the current mainstream solution. The characteristics of electric vehicles such as zero pollution, low noise, high energy conversion efficiency, and good acceleration have become a transportation tool that has attracted much attention. An important development direction of major car manufacturers. Among them, the three batteries (battery, motor and electric control) are the most important components of electric vehicles, and the motor controller is one of the cores of the drive control system of electric vehicles. [0003] Compared with the traditional way of using a single motor to provide power, the technology of the dual-motor control system of one-to-...
