Problems solved by technology

[0002] At present, most vehicles will automatically turn off the fan of the air intake grille during high-speed driving, and the driver will usually close the window and sunroof to reduce wind noise and driving resistance during high-speed driving. However, when the driver When braking the vehicle, these measures to reduce driving resistance will instead increase the braking distance and affect driving safety

Embodiment 1

[0042] see figure 1 The flow of the vehicle auxiliary control method for emergency braking provided by Embodiment 1 of the present invention is as follows:

[0043] First, it is judged whether the vehicle is currently in an emergency braking condition.

[0044] The judgment of the emergency braking condition is based on the preset trigger conditions, which can be flexibly set according to the needs. Usually, some of the following conditions can be selected and combined to form the preset trigger conditions. These conditions are: ①The vehicle controller receives the collision warning signal from the collision warning system; ②The current vehicle speed fed back by the vehicle speed sensor is greater than the preset vehicle speed value; ③The current following distance fed back by the following distance sensor is smaller than the preset vehicle distance value; ④The current acceleration fed back by the acceleration sensor is a negative value and less than the preset deceleration v...

Embodiment 2

[0056] see figure 2 The difference between Embodiment 2 and Embodiment 1 is that, compared with Embodiment 1, Embodiment 2 further includes controlling the opening of the sunroof after determining that the vehicle is currently in an emergency braking condition. Similar to opening a car window, opening the sunroof can increase air resistance and help reduce the braking distance.

[0057] Similar to the situation described above, only one or two of the three control modes of controlling the reverse rotation of the fan, controlling the opening of the car window and controlling the opening of the sunroof can be reserved, which can also increase the drag coefficient of the vehicle, but the effect is better than that of the second embodiment. Weaker.

Embodiment 3

[0059] see image 3 , on the basis of the second embodiment, the third embodiment adds the step of judging whether the current environment outside the vehicle is rainy or snowy. Make sure that the opening of the windows and sunroof will not adversely affect the occupants of the vehicle.

[0060] In specific practical applications, it is possible to judge whether the current environment outside the vehicle is rainy or snowy by collecting the signal of the on-board rain sensor. The on-board rain sensor can be a flow-type rain sensor, an electrostatic rain sensor, a piezoelectric rain sensor or an infrared rain sensor. .

[0061] In the above embodiments, in order to avoid shaking of the vehicle due to the sudden opening of the windows, the windows on both sides of the vehicle can be controlled to open symmetrically, that is, the windows on both sides of the vehicle are opened synchronously.

[0062] Based on the vehicle auxiliary control method provided by the present inventio...

Abstract

The invention provides a vehicle and a vehicle auxiliary control method, device and system for emergency braking. The vehicle auxiliary control method comprises the following steps: when the vehicle is in an emergency braking working condition, the vehicle is controlled to enter an emergency braking auxiliary mode, and the emergency braking auxiliary mode comprises at least one of the following control modes: a control mode a, a fan at an automobile water tank is controlled to rotate reversely, so that the fan blows air towards the automobile head; a control mode b, an automobile window is controlled to open; and a control mode c, a skylight is controlled to open. By adopting the vehicle auxiliary control method provided by the invention, the safety of the braking process can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle and a vehicle auxiliary control method, device and system for emergency braking. Background technique [0002] At present, most vehicles will automatically turn off the fan of the air intake grille during high-speed driving, and the driver will usually close the window and sunroof to reduce wind noise and driving resistance during high-speed driving. However, when the driver When braking the vehicle, these measures to reduce driving resistance will instead increase the braking distance and affect driving safety. Therefore, how to provide a safer emergency braking method for high-speed driving conditions has become a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0003] In view of this, the present invention provides a vehicle and a vehicle auxiliary control method, device and system for emergency braking. Using th...
