A sanitation vehicle equipped with a motor parallel control system and a sanitation vehicle

Abstract

The invention relates to a sanitation vehicle top-mounted motor parallel control system and a sanitation vehicle. The control system includes an integrated motor controller and a top-mounted motor. The integrated motor controller includes a first motor controller and a second motor controller. The first motor controls The high-voltage output interface of the controller and the high-voltage output interface of the second motor controller are connected to the high-voltage input interface of the bodywork motor. The first motor controller and the second motor controller are set in parallel, and the current input to the bodywork motor is the sum of the currents of the two motor controllers, which meets the power demand of the bodywork motor and can ensure the normal operation of the bodywork motor. The control system makes full use of the resources of the integrated motor controller, does not need to be specially installed on the motor controller, avoids the defect of large redundant capacity of the motor controller, reduces the number of motor controllers, reduces the cost of the whole vehicle, and reduces high-voltage connection points , Simplify the drive system of the upper body motor and improve the reliability of the vehicle.

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 ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a parallel control system for motors installed on sanitation vehicles, which is used to solve the problem that the existing sanitation vehicle electric control system has a large number of controllers and large capacity redundancy, resulting in high cost, many high-voltage nodes and system complicated question

The present invention also provides a sanitation vehicle, which is used to solve the problems of high cost, many high-voltage nodes, and complicated system due to the large number of controllers and large capacity redundancy in the electronic control system of the existing sanitation vehicle
