Embodiment 1

[0038] figure 1 It is a schematic flowchart of a vehicle braking control method provided in Embodiment 1 of the present invention. The method can be executed by a vehicle braking control device. The device can be composed of hardware and / or software. The device can be integrated with the vehicle's in the brake controller. The brake control method of the vehicle provided by Embodiment 1 of the present invention includes the following steps:

[0039] S110. Obtain obstacle information around the vehicle and the current driving state of the vehicle.

[0040] Among them, during the normal driving process of the vehicle, there are different obstacles around the vehicle. During the driving process of the vehicle, the obstacles around the vehicle will prevent the vehicle from moving forward or backward, etc. The obstacles can be static obstacles, such as trees, signboards, etc. , buildings, etc., can also be dynamic obstacles, such as other vehicles, people, etc.; therefore, by obta...

Embodiment 2

[0056] image 3 Embodiment 2 of the present invention is a schematic flow chart of a braking control method for a vehicle. On the basis of the above embodiments, it specifically provides a solution for predicting whether the vehicle will collide with an obstacle when driving in the current driving state. The technical scheme of the present embodiment includes:

[0057] S210. Obtain obstacle information around the vehicle and the current driving state of the vehicle.

[0058] S220. Determine the relative distance between the vehicle and the obstacle in the driving direction according to the obstacle information.

[0059] S230. Predict whether the vehicle collides with an obstacle when traveling along the traveling direction according to the traveling speed and the relative distance; if yes, execute S240.

[0060] Among them, the driving speed refers to the speed at which the vehicle moves forward in the current direction; the relative distance refers to the relative distance ...

Embodiment 3

[0067] Figure 4 It is a schematic flowchart of a braking control method for a vehicle provided by Embodiment 3 of the present invention. On the basis of the above embodiments, it also includes, according to the relationship between the driving speed of the vehicle and the first preset vehicle speed and the second preset vehicle speed, Adjust the deceleration of the vehicle appropriately. The braking control method of the vehicle provided by Embodiment 3 of the present invention includes:

[0068] S301. Obtain obstacle information around the vehicle and the current driving state of the vehicle.

[0069] S302. According to the obstacle information and the current driving state, predict whether the vehicle collides with the obstacle when the vehicle is controlled by the current driving state; if yes, execute S303; if not, execute S309.

[0070] S303. Obtain an expected deceleration corresponding to the driver's braking expectation.

[0071] S304. Predict whether the vehicle c...

Abstract

The embodiment of the invention discloses a vehicle braking control method and device, a vehicle and a storage medium. The method comprises the following steps: acquiring information of obstacles around a vehicle and a current driving state of the vehicle; according to the obstacle information and the current driving state, whether the vehicle collides with the obstacle or not when the vehicle is controlled to run in the current driving state is pre-judged; if yes, the predicted deceleration corresponding to the braking expectation of the driver is obtained; pre-judging whether the vehicle collides with an obstacle or not when the vehicle is controlled to decelerate at the predicted deceleration; if yes, the vehicle is controlled to decelerate at the actual deceleration larger than the predicted deceleration. According to the technical scheme, the deceleration of the vehicle can be controlled in time, the vehicle is prevented from colliding with an obstacle, the safety of the vehicle and a driver is guaranteed, and meanwhile the driving comfort of the driver is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of automobile control, and in particular, to a vehicle braking control method, device, vehicle and storage medium. Background technique [0002] The vehicle braking system is the core component of the entire vehicle, which can effectively protect the driver's personal safety. In the prior art, the brake controller in the vehicle brake system can control the vehicle to decelerate according to the driver's braking demand. [0003] In the prior art, the brake controller of the vehicle only controls the deceleration of the vehicle to decelerate according to the strength of the driver stepping on the brake pedal. However, when there is an obstacle in the driving direction of the vehicle and the current driver depresses the brake pedal with insufficient strength, the vehicle will collide with the obstacle, which will damage the vehicle and endanger the life of the driver.
