Problems solved by technology

[0003] Traditional traction trucks mainly use traditional friction braking. The driver steps on the brake pedal to rub against the brake pads; some high-end trucks are equipped with a retarder. Slow speed and then trailer slow speed, but these two methods have the problem of poor slow speed effect, the braking distance is long, and it is easy to appear the phenomenon of pushing the front of the trailer to push the front of the car, which poses a safety hazard

Embodiment Construction

[0029] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0030] In one embodiment, such as figure 1 As shown, a truck retarding control method is provided, which can be applied to the control device; the application of the method to the control device is used as an example for illustration, including the following steps:

[0031] S110: Receive an operation signal sent by the slow speed operation device.

[0032] The slow operation device is a device that can be operated by the driver or the smart device that can perform the operation task. The operation performed by the driver or the smart device is called an external operation...

Abstract

The invention relates to a truck retarding control method and control device and truck retarding equipment. The method comprises the following steps that an operation signal sent by a retarding operating device is received, if the operation signal is a trailer retarding indication signal, a trailer gear of a trailer retarding working mode is obtained according to the trailer retarding indication signal, a trailer retarder arranged on a trailer is controlled to carry out retarding working in the trailer gear of the trailer retarding working mode, if the operation signal is a combined retardingindication signal, a truck head gear and a trailer gear of a combined retarding working mode are acquired according to the combined retarding indication signal, a truck head retarder arranged at a vehicle head is controlled to carry out retarding working in the truck head gear, and the trailer retarder is controlled to carry out retarding working in the trailer gear of the combined retarding working mode. By adopting the method, the braking distance can be shortened, obstacles can be avoided in time, the phenomena of understeer and oversteer can be avoided, and the safety is high.

Description

technical field [0001] The present application relates to the technical field of vehicle control, in particular to a truck retarding control method, a control device and truck retarding equipment. Background technique [0002] A truck is a means of transport for transporting goods; a tractor-type truck includes a tractor head and a trailer towed by the head. When the driver drives the truck, there will inevitably be slowing or braking requirements, such as the need to slow down when driving downhill. [0003] Traditional traction trucks mainly use traditional friction braking. The driver steps on the brake pedal to rub against the brake pads; some high-end trucks are equipped with a retarder. Slowing down and then trailer slowing down, but both of these two methods have the problem of poor slowing effect, the braking distance is long, and it is prone to the phenomenon of pushing the front of the car with the trailer pushing the front of the car, which has potential safety h...
