Abstract

The invention relates to the field of electric vehicle driving control, in particular to a controller for a driving system of an electric vehicle. A vehicle speed sensor, an accelerator pedal position sensor, a braking device pedal force sensor, an amplifier for detected current and an amplifier for sensor signals are all electrically connected with a microcomputer. A current detection device is electrically connected with the amplifier for the detected current. A vehicle position sensor is electrically connected with the amplifier for the sensor signals. The microcomputer is electrically connected with a first pre-driver and a second pre-driver. The first pre-driver is electrically connected with a first inverter. The second pre-driver is electrically connected with a second inverter. An engine is electrically connected with the first inverter and the second inverter. The controller for the driving system of the electric vehicle is convenient to use, low in manufacturing cost and safer.

Description

technical field [0001] The invention belongs to the field of driving control of electric vehicles, and in particular relates to a controller of a driving system of an electric vehicle. Background technique [0002] Typically, a drive system for a vehicle includes a prime mover, usually outputting constant power, that powers a generator that in turn drives a motor for each wheel. System reaction speed, maneuverability, and changing conditions are usually irrelevant. When such a drive system carries a load with multiple degrees of freedom, and the resonant frequency is lower than that of the drive system itself, maneuvering of the vehicle is difficult, if not impossible. In an electric drive device applied to an electric power steering system of a vehicle that assists a driver's steering operation of the vehicle, it is known in the art that an electric motor and a controller for driving and controlling the electric motor are integrated into one, according to the above control...
