Problems solved by technology

[0002]The car formation is usually composed of a tractor car and an attached vehicle. When the tractor car is connected to multiple trailers, the length of the vehicle formation formed is relatively long (≥70m) , when each trailer is full of goods, the driving inertia is large, and the braking distance of the whole train is too long
And when the vehicle formation is in downhill, turning, emergency braking and other working conditions, the rear vehicle will impact the front vehicle due to inertia, which will cause the entire group of vehicles to flick and roll over or the front vehicle will lose control, resulting in serious safety accidents

Embodiment 1

[0045] The embodiment of the present application provides a vehicle formation braking control method, which is applied to a vehicle formation including at least two articulated vehicles 200 . For example, the typical "one-trailer-two-twist" combination vehicle marshalling, please refer to figure 1 , the vehicle grouping is a trailer grouping, adopting the combination method of "one trailer and two trailers", that is, the trailer grouping includes the tractor vehicle 100 and two articulated vehicles 200, and the tractor vehicle 100 and the two articulated vehicles 200 Agencies end to end.

[0046] The control logic of the vehicle formation braking control method in this embodiment is as follows: during the braking process, when the vehicle speed of the articulated vehicle 200 at the front is lower than the vehicle speed of the articulated vehicle 200 at the rear, and / or, when two adjacent When the body postures of the two articulated vehicles 200 are different in the driving d...

Embodiment 2

[0063] Based on the same inventive concept, an embodiment of the present application provides a vehicle formation, which adopts the braking control method of the vehicle formation in Embodiment 1 above when braking. Similar to the prior art, the vehicle formation in this embodiment also includes a tractor vehicle 100 and at least two articulated vehicles 200 articulated at the rear end of the tractor vehicle 100 .

[0064] Taking the air pressure braking system as an example, the current vehicle formation usually uses an air source provided by the tractor car 100 air reservoir to perform braking control on the vehicle formation. However, when the number of articulated vehicles 200 increases, the brake pipeline of the rear vehicle 220 is too long, and there is a large air pressure loss, so the rear vehicle 220 is prone to insufficient braking force, causing the rear vehicle 220 to impact the front vehicle 210 . At the same time, due to the limited volume and air pressure of the...

Abstract

The invention discloses a vehicle marshalling braking control method and a vehicle marshalling. The problems that in the prior art, due to insufficient braking of a rear vehicle, the rear vehicle impacts a front vehicle to turn over, and the braking distance of the whole train is too long are solved. According to the vehicle marshalling braking control method, when the speed of the front hitch vehicle is smaller than that of the rear hitch vehicle, and / or when the vehicle body postures in the driving directions of the two adjacent hitch vehicles are different, the braking force of all the hitch vehicles is adjusted, and the braking force of all the hitch vehicles is adjusted. The driving speed of the front hitch vehicle is not smaller than that of the rear hitch vehicle. According to the vehicle marshalling braking control method, unequal braking force is applied to the front vehicle and the rear vehicle, so that the running speed of the front vehicle is higher than that of the rear vehicle, the trend that the front vehicle drags the rear vehicle to run forwards is presented, and the purpose of correcting the running posture of the vehicle is achieved.

Description

technical field [0001] The present application belongs to the technical field of braking control, and in particular relates to a vehicle formation braking control method and a vehicle formation. Background technique [0002] Vehicle marshalling is usually composed of a tractor car and an attached vehicle. When the tractor car is connected to multiple trailers, the length of the vehicle marshalling formed is longer (≥70m). When each trailer is full of goods, the driving inertia is large. The braking distance of the whole train is too long. And when the vehicle formation is in downhill, turning, emergency braking and other working conditions, the rear vehicle will impact the front vehicle due to inertia, which will cause the entire group of vehicles to flick and rollover or the front vehicle will lose control, resulting in serious safety accidents. [0003] The high stability of the braking process is a necessary condition for the normal, stable and safe operation of the vehi...
