Problems solved by technology

[0003] At present, the electric eddy current retarder with air-cooled structure is widely used in the market. The temperature of the main body can reach 650°C during continuous operation, while the electro-hydraulic retarder realizes water cooling, and the heat of the main body is taken away by the internal coolant, which greatly reduces the The performance of the electro-hydraulic retarder has been improved, but the current controller for the electro-hydraulic retarder is a simple relay control box, which can only provide simple input and output, and cannot communicate with the vehicle in real time. The running state cannot be controlled in real time, and the function is simple, and it is impossible to limit the speed of the vehicle in combination with the overall performance of the vehicle system

Abstract

The invention discloses a controller for an automobile electromagnetic liquid cooling retarder, comprising: a control device, which includes: a processor; a system monitoring module, which is connected to the processor; and a speed comparison module, which is connected to a vehicle speed sensor The monitoring module and the speed comparison module are used to compare the speed of the vehicle with the vehicle speed threshold. When the speed of the vehicle is greater than the vehicle speed threshold, the speed comparison module transmits a signal to the processor to control the slowing speed through the processor. The vehicle speed is decelerated by the operation of the controller; the gear position switching module is connected to the speed comparison module and the processor, the gear position switching module; the automatic cruise module. The invention greatly reduces the safety blind spots of the electro-hydraulic retarder, eliminates the potential safety hazards of the vehicle caused by the retarder, and can compare the speed signal when the vehicle goes downhill, and then automatically activates the retarder body. The vehicle slows down.

Description

technical field [0001] The invention relates to the field of electromagnetic liquid cooling retarder control, in particular to a controller for an automobile electromagnetic liquid cooling retarder. Background technique [0002] As an auxiliary braking device, electromagnetic liquid-cooled retarder is increasingly used in buses, heavy-duty commercial vehicles and trucks. The electro-hydraulic retarder can provide a wide range of specified torque for the vehicle, avoiding safety hazards such as brake failure, tire blowout and vehicle deviation, while reducing the wear and tear of the vehicle brake system, reducing noise, and bringing economic benefits to customers. [0003] At present, the electric eddy current retarder with air-cooled structure is widely used in the market. The temperature of the main body can reach 650°C during continuous operation, while the electro-hydraulic retarder realizes water cooling, and the heat of the main body is taken away by the internal coola...
