New-energy entire car controller integrated with transmission case control function

Abstract

The invention provides a new-energy entire car controller integrated with a transmission case control function. The controller is integrated with the transmission case control function, i.e., an original entire car control function and a transmission case control function are integrated in the entire car controller, so that a special TCU (transmission control unit) is not needed any more; analog input, on-off input and frequency input are connected with respective sensors; a power-driven part and a motor-driven part are connected with respective actuators; the components are connected together with an internal bus on a controller circuit board by virtue of internal connecting wires so as to form a complete controller hardware circuit. New-energy entire car controller software integrated with the transmission case control function is realized by virtue of an entire car control algorithm and a transmission case control algorithm. The new-energy entire car controller can be used for shortening the development cycle, lowering the development cost, reducing automobile parts such as a controller, an auxiliary connector and wire harnesses and lowering the purchase costs of the parts.

Description

technical field [0001] The invention relates to a new energy vehicle controller with an integrated gearbox control function, which belongs to the technology of new energy vehicles, in particular to the technology of electric control systems of new energy vehicles. Background technique [0002] As the main development direction of future automobiles, new energy vehicles, especially pure electric vehicles, have been supported and encouraged by the state. With the strong support of national policies and the gradual breakthrough of key technologies, the new energy automobile industry has a good prospect. [0003] TCU (Transmission Control Unit) is an automatic transmission control unit, which is often used in automatic transmissions such as AMT, AT, DCT, and CVT. Realize automatic variable speed control to make driving easier. [0004] MCU (Motor control unit) is the motor control unit, also known as the motor controller, which is responsible for the control of the main drive ...

AI Technical Summary

Problems solved by technology

[0007] Since the transmission control unit TCU is responsible for automatic transmission control, its functions are complex and costly, and the existence of the TCU makes the original limited interior space layout and wiring more difficult, and increases the workload and maintenance work when the vehicle breaks down.
