Abstract

The invention relates to an automobile controller, in particular to an electric automobile controller integrated with an MCU and a TCU, which comprises an ECU integrated with the TCU, the ECU is connected with a control signal acquisition unit used for acquiring vehicle control signals, and the control signal acquisition unit comprises an analog signal acquisition module used for acquiring analog input signals, and a digital signal acquisition module which is used for acquiring digital input signals; the ECU is connected with a state data acquisition module for acquiring vehicle state data, and is connected with a data processing module for processing a vehicle control signal and the vehicle state data to generate change rate data; the ECU is connected with a data comparison module used for comparing the change rate data with set parameters, and the ECU is connected with a driving state judgment module used for judging the driving state according to a data comparison result; and according to the technical scheme, the defects that the smoothness is poor in the driving process, and the safe speed control function is not achieved can be effectively overcome.

Description

technical field [0001] The invention relates to an automobile controller, in particular to an electric automobile controller integrating an MCU and a TCU. Background technique [0002] With the increasingly serious problems of energy depletion and environmental pollution, countries around the world are actively seeking to develop low-emission, high-efficiency new energy vehicles. New energy vehicles are regarded as one of the important ways to solve the above problems and have attracted widespread attention. [0003] The transmission in pure electric vehicles has a significant effect on the overall performance of the vehicle, and the operating curve of the motor has obvious advantages over traditional engines. The power shifting process has a better shifting quality, and its control process is more complicated than that of the non-power shifting process. The motor speed synchronization process requires the motor speed to be adjusted quickly, accurately, and stably. The speed...
