Problems solved by technology

The hybrid power mode of the present invention belongs to the mild hybrid power system. Since the power source of the entire power system becomes the output of two powers of the engine and the motor, the power of the motor is controllable, so the platform of the hybrid powertrain is different. Compared with the traditional engine assembly platform, it is necessary to consider the influence of the power output of the motor, as well as multiple controllers such as the engine management unit, multi-energy control unit, motor controller and battery management unit, and the synchronous operation mode, so the traditional engine platform The test bench can no longer meet the test requirements of the hybrid power bench

Embodiment Construction

[0007] As shown in Figure 1, the hybrid vehicle powertrain bench test device is composed of front, rear, left and right brackets according to the installation method of the engine 10, the torque sensor 40, the motor 70, the gearbox 80 and the fixed position of the crankshaft position sensor. Bench, the powertrain is installed on the bench, the dynamometer 90 is connected to the power output end of the gearbox 80, and the torque sensor 40 is set between the engine 10 and the motor 70 and / or between the motor 70 and the dynamometer 90 .

[0008] The preferred solution is to set the torque sensor 40 between the engine 10 and the motor 70 and between the motor 70 and the dynamometer 90, the torque sensor 40 is fixedly arranged on the support 50, and each part of the powertrain and the torque sensor 40, the dynamometer Machine 90 is highly consistent with the centerline of the powertrain.

[0009] The torque sensor 40 has a base and a bracket 50 to fix it,

[0010] There is a bas...

Abstract

The invention relates to mixed power electric automobile power assembly bench test device. Front, back, left, and right frames are formed bench according to the mounting means of engine, torque sensor, electric machine, gear box and the sensor fixing position at the crank shaft. Power assembly is set at the bench. Power measuring machine is connected with the power output end of the gear box. Torque sensor is set between the engine and the electric machine or power measuring machine. The connected power assembly, torque sensor, and power measuring machine are connected with each controller unit and related wiring harness to constructer CAN network, adjust system communicating, verify reliability and system function for engine, electric machine, battery, HCU multi energy sources controller, BMS battery management unit, MCU electric machine controller, EMS engine controller etc.

Description

technical field [0001] The invention relates to a power assembly bench test technology of a parallel hybrid electric vehicle, and mainly refers to a layout plan of a hybrid power bench. Background technique [0002] Since the 1990s, major automobile companies in Japan, the United States, and Europe have begun to develop hybrid vehicles. Since Japan's Toyota first launched a hybrid car in 1997, major car companies including Honda, General Motors, Ford, D-C and French Citroen have launched or developed product cars or concept prototypes. Experts believe that in the next ten years, 40% of cars may adopt hybrid technology, the development and adoption of hybrid technology depends on reliable market factors, government incentives and regulations will lead consumers and manufacturers to invest and choose to adopt technology. Mild hybrid systems are expected to take a significant market share. The hybrid power mode of the present invention belongs to the mild hybrid power system...
