However, when there are snow, ice, water, sand and other substances on the road surface that can significantly reduce the friction coefficient between the tire and the ground, only by reducing the running speed of the wheel, the deceleration cannot be effectively achieved. Often the brakes have been stepped on to the bottom, but the tire and the road surface Skidding occurs, causing the vehicle to fail to decelerate and stop normally, deviation, side skidding, and even out-of-control phenomena such as vehicle circling on the road, causing vehicle collisions, and even endangering the lives and property safety of people inside and outside the vehicle
[0003] The ABS system currently equipped with vehicles is designed to prevent the tires from being locked for a long time during the braking process, resulting in the vehicle being unable to steer and control. It becomes the pulse intermittent squeeze, which can make the driver adjust the direction of the car during the braking process. Its essence is to decelerate through wheel braking, which cannot guarantee the effective braking distance on slippery roads.

Embodiment 1
[0052] see figure 2 , which is a schematic diagram of Embodiment 1 of the auxiliary braking system provided by the present invention.
[0053] The auxiliary braking system provided in this embodiment includes: a starting module 100, a control module 200, a driving module 300, an auxiliary braking mechanism 400, and a pedal position displacement sensor 500;
[0054] The starting module 100 includes a first switch 1000 and a second switch 1001, the first switch 1000 is a prohibition / validation switch, which is used to set the prohibition state or the effective state of the auxiliary braking system; the second switch 1001 is used to Set the auxiliary braking system to manual mode or automatic mode.
[0055] It can be understood that, when the driver thinks that the ice and snow on the road may affect the normal braking according to the road conditions, the driver will set the first switch 1000 to an active state and send a start permission signal to the control module 200 .

[0068] The auxiliary braking system provided in this embodiment includes: a starting module 100, a control module 200, a driving module 300, an auxiliary braking mechanism 400, and a pedal position displacement sensor 500;
[0069] The starting module 100 includes a first switch 1000 and a second switch 1001, the first switch 1000 is a prohibition / validation switch, which is used to set the prohibition state or the effective state of the auxiliary braking system; the second switch 1001 is used to Set the auxiliary braking system to manual mode or automatic mode.
[0070] It can be understood that, when the driver thinks that the ice and snow on the road may affect the normal braking according to the road conditions, the driver will set the first switch 1000 to an active state and send a start permission signal to the control module 200 .

Abstract
The invention discloses an auxiliary braking system of a vehicle. The auxiliary braking system of the vehicle comprises a starting module, a control module, a driving module and an auxiliary braking mechanism, wherein the starting module is used for judging whether the vehicle accords with conditions of starting the auxiliary braking system or not, and transmitting a starting allowing signal to the control module; the control module is used for transmitting a movement instruction for controlling the auxiliary braking mechanism to move to the driving module according to the related information of vehicle braking when receiving the starting allowing signal; the driving module is used for controlling the auxiliary braking mechanism to move according to the movement instruction of the control module; and the auxiliary braking mechanism is in contact with a road surface to generate resistance under the control of the driving module, and is used for helping the vehicle to decelerate. The invention further provides a control method of the auxiliary braking system of the vehicle. By adopting the auxiliary braking system which is independent from an existing braking system, the control module of the system is used for controlling the auxiliary braking system to independently press down to effectively rub the road surface, and can be used for assisting vehicle tires to effectively brake the vehicle in time.
Description
technical field [0001] The invention belongs to the technical field of vehicle control, in particular to a vehicle auxiliary braking system and a control method. Background technique [0002] The braking devices of existing vehicles are produced by brake calipers pressing brake discs or brake shoes squeezing brake drums. The power sources are divided into oil brakes and air brakes. Speed or stop rotation to achieve the purpose of braking. However, when there are snow, ice, water, sand and other substances on the road surface that can significantly reduce the friction coefficient between the tire and the ground, only by reducing the running speed of the wheel, the deceleration cannot be effectively achieved. Often the brakes have been stepped on to the bottom, but the tire and the road surface Skidding occurs, causing the vehicle to fail to decelerate and stop normally, and there are out-of-control phenomena such as running deviation, side skidding, and even the vehicle tu...
