Distribution type driving control system testing platform

Abstract

The invention discloses a distribution type driving control system testing platform which comprises a battery simulator, wherein the battery simulator is respectively and electrically connected with amain control system and a motor controller; the main control system is electrically connected with a tested overall controller; the tested overall controller is electrically connected with a motor controller; the motor controller is respectively and electrically connected with a motor simulator I and a motor simulator II ; input ends of the motor simulator I and the motor simulator II are electrically connected with a 380V voltage and used as actual motor loads to test voltage and current parameters output from a control system; a power analyzer is respectively and electrically connected withthe battery simulator, the main control system, the motor simulator I and the motor simulator II. By adopting the testing platform, actual motor loads are replaced by power grade motor simulators, testing can be carried out by using a power grade motor simulator matched with distribution type driving, motors, power testers, torque rotation speed sensors, and the like are avoided, and the space, cost and time are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of motor controller testing, in particular to a test bench for a distributed drive control system. Background technique [0002] With the development of motor and electronic control technology, it is possible to install a motor on the wheel hub to directly drive the vehicle. The power system of this motor including the motor controller and the vehicle controller is called a distributed drive system. Compared with The centralized drive system and the distributed drive system eliminate the need for reducers, differentials and half shafts. This structure is very compact and has high transmission efficiency. Therefore, distributed drive is a distributed drive technology applied to vehicles in recent years. At present, when testing the performance of the motor controller, it is necessary to use the load motor and the dynamometer to build an actual test bench. For the test of the distributed drive system, at leas...

AI Technical Summary

Problems solved by technology

At present, when testing the performance of the motor controller, it is necessary to use the load motor and the dynamometer to build an actual test bench. For the test of the distributed drive system, at least two motors are required as the load of the motor controller, and the dynamometer is required as the mechanical mechanism of the motor. The development of load, motor and control system is often parallel, and even the manufacturer that develops the control system does not develop the motor, which brings certain difficulties to the test of the distributed drive control system, and the whole test preparation time is longer, involving To the shafting alignment of the motor and the dynamometer, a large investment in testing time and cost
