Example Embodiment

[0036] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment of the various embodiments of the present invention.

[0037] figure 1 It is the overall structure diagram of the test bench. The connection method is: the front drive engine and the auxiliary motor are connected through the gearbox, differential, half shaft, torque and speed sensor and dynamometer, and the rear drive motor is connected through the transmission mechanism, half shaft, torque speed and speed. The sensor is connected to the rear-drive dynamometer, the drive motor is connected to the dynamometer through a coupling, a torque and speed sensor, and the battery pack and the motor's inverter are connected to a high-voltage wire harness. The vehicle controller accepts external signals, and sends power generation torque requests and driving torque requirements to the generator set controller and motor controller according to the vehicle c...

Abstract

The invention relates to a test bench and a mounting method and a testing method thereof. The test bench is used for a four-wheel-drive strong-mixing power assembly system test and comprises an engine and controller thereof, a driving motor and controller thereof, speed shifting mechanisms, an entire vehicle controller and dynamometers, wherein the speed shifting mechanisms comprise a first speed shifting mechanism and a second speed shifting mechanism; the dynamometers comprise a front-drive dynamometer and a rear-drive dynamometer; the engine is connected with the front-drive dynamometer through the first speed shifting mechanism; the driving motor is connected with the rear-drive dynamometer through the second speed shifting mechanism; the entire vehicle controller is used for receiving a signal from the outside and transmitting a generation torque request and a driving torque demand to the driving motor controller and the engine controller according to the entire vehicle control strategy; the engine controller is in controlled connection with the engine; and the driving motor controller is in controlled connection with the driving motor.

Description

technical field [0001] The invention relates to a test bench scheme of a four-wheel drive strong hybrid powertrain system, in particular to a test bench and its installation method and testing method. Background technique [0002] With the continuous improvement of new energy policies, the industrialization process of new energy vehicles in my country has accelerated. However, limited driving range and high battery costs have been the main obstacles to the adoption of electric vehicles. The four-wheel drive strong hybrid vehicle is driven by the combination of the engine and the auxiliary motor for the front drive, and the drive motor for the rear drive, and the battery stores energy. During the operation of the vehicle, it can be independently driven by the front drive, single drive by the rear drive, or four-wheel drive according to different working conditions. mode operation. Therefore, this powertrain system test bench needs to change the drive mode, energy supply mod...
