Embodiment Construction

[0017] Example of sanitation vehicle

[0018] This embodiment provides a kind of sanitation vehicle, taking the pure electric sanitation vehicle as an example, of course, it can also be a hybrid sanitation vehicle. The sanitation vehicle is provided with a top-mounted motor parallel control system to realize the control of the top-mounted motor. Since the other components of the sanitation vehicle are not the invention points of the claimed sanitation vehicle, they will not be repeated here.

[0019] The bodywork motor parallel control system includes an integrated motor controller and a bodywork motor. The integrated motor controller can be a three-in-one or even an all-in-one controller commonly used in new energy vehicles, including at least two motor controllers. The two motor controllers are respectively It is the first motor controller and the second motor controller, and the capacity of a single motor controller cannot meet the continuous long-term operation of the bod...

Abstract

The invention relates to a sanitation vehicle upper-part motor parallel control system and a sanitation vehicle. The control system comprises an integrated motor controller and an upper-part motor, wherein the integrated motor controller comprises a first motor controller and a second motor controller, and a high-voltage output connector of the first motor controller and a high-voltage output connector of the second motor controller are connected with a high-voltage input connector of the upper-part motor. The first motor controller and the second motor controller are arranged in parallel, anda current input to the upper-part motor is the sum of currents of the two motor controllers, thereby meeting the power requirement of the upper-part motor and being capable of ensuring the normal operation of the upper-part motor. The control system makes full use of resources of the integrated motor controller, and does not need to specially arrange a motor controller, thereby avoiding the defect of large redundancy of the motor controller capacity, reducing the number of the motor controllers, reducing vehicle cost, reducing high-voltage connection points, simplifying a drive system of theupper-part motor, and improving vehicle reliability.

Description

technical field [0001] The invention relates to a motor parallel control system mounted on a sanitation vehicle and a sanitation vehicle. Background technique [0002] The bodywork motor is the main source of power for the pure electric sanitation vehicle to perform sanitation operations, and the normal operation of the bodywork motor needs to be matched with a suitable bodywork motor controller. For example, the Chinese patent document with the authorized announcement number CN206589716U discloses an electric control system for a pure electric road maintenance vehicle, including a chassis power supply system and a bodywork electronic control system. The controller is connected to the bodywork motor. Integrated motor controllers are widely used in pure electric sanitation vehicles due to their advantages in size, weight, cost and reliability. The current integrated motor controllers are usually composed of steering motor controllers, air compressor motor controllers, drive ...
