Embodiment

[0030] Such as figure 1 As shown, the present invention is used for the braking distance judging system of the sudden braking of large trucks, comprising a control unit 1 connected to the braking system, and more than one pressure sensor 4 arranged on the front inner wall of the compartment, arranged on the vehicle body and connected to the control unit 1 The connected acceleration sensor 3 ; the distance sensor 6 , the storage unit 7 and the gyroscope 8 are also connected to the control unit 1 ; the pressure sensor 4 is connected to the control unit 1 . The control unit 1 is also connected with a weight sensor 2 respectively installed on each wheel under the compartment.

[0031] The concrete judgment method of this embodiment is as follows:

[0032] First, through the pressure sensor, the pressure when the cargo is squeezed on the front inner wall of the compartment is sensed in time. When the pressure exceeds a certain value, the instantaneous speed change rate is sensed t...

Embodiment 2

[0040] The difference between this embodiment and Embodiment 1 is that this embodiment adds a weight sensor 2 and a force guiding wall 5, such as figure 1 As shown, the details are as follows:

[0041] The control unit 1 is also connected with a weight sensor 2 respectively installed on each wheel under the compartment. The pressure sensor 4 is connected with a force guiding wall 5 for guiding the pressure of objects in the compartment to the front wall of the compartment.

Embodiment 3

[0043]The difference between this embodiment and Embodiment 2 is that in this embodiment, the structural arrangement between the force guiding wall 5 and the pressure sensor 4 is optimized, as follows:

[0044] The guide wall 5 is a mesh wall structure formed by fixing sheet steel bars, such as figure 2 As shown; there are multiple pressure sensors 4, which are installed and arranged in concentric circles on the force-guiding wall 5.

Abstract

The invention discloses a braking distance judgment system for emergency braking of a truck and a judgment method. The problem that when large heavy cargos are carried in a cargo compartment, a truck head is likely to be damaged due to the fact that the cargos rush forwards and move in the emergency braking process, and thus safety accidents are caused is solved. The braking distance judgment system comprises a control unit (1) connected with a braking system, one or more pressure sensors arranged on the inner wall in the front of the compartment and an acceleration sensor (3) arranged on a truck body and connected with the control unit (1). A distance sensor (6), a storage unit (7) and a gyroscope (8) are connected to the control unit (1). The pressure sensors (4) are all connected to the control unit (1). By the adoption of the braking distance judgment system, the speed variation rate during emergency braking can be adjusted effectively through the control unit, the situation that the cargos rush forwards during emergency braking, and the safety of drivers is influenced is prevented, and the position with the maximum forward-rush pressure can be effectively detected while the protective capability is enhanced.

Description

technical field [0001] The invention relates to a braking distance judging system, in particular to a braking distance judging system and a judging method for sudden braking of large trucks. Background technique [0002] When the truck is transporting goods, if the cargo in the cargo compartment is not full, when the truck is driving on a bumpy road or turning, the cargo loaded in the cargo compartment will shift, and the cargo will move easily damaged during the process. [0003] Even, when the truck is running at high speed on the highway, especially on the expressway, if the cargo compartment is loaded with heavy goods and encounters sudden braking, due to the heavy weight of the goods, the inertia of the goods during the sudden braking will be caused. The bigger it is, the easier it is to make the goods move forward, which will easily cause the goods to damage the front of the car and cause safety accidents for drivers. Contents of the invention [0004] The purpose ...
