Embodiment 1

[0046] refer to figure 1 , showing a flow chart of the steps of a driving protection method of the present application, such as figure 1 As shown, a driving protection method includes:

[0047] Step S101 : when it is detected that an obstacle exists within a preset distance range, the distance of the obstacle from the vehicle is obtained.

[0048] In this step, the distance between the obstacle and the vehicle may be the distance between the obstacle and the front of the vehicle, or the distance between the obstacle and the rear of the vehicle; the distance can be obtained through the front and rear radars of the vehicle.

[0049] Step S102: Trigger the driving protection mode when the distance is less than the first preset distance threshold and the accelerator opening of the vehicle is greater than the preset accelerator opening threshold.

[0050] In this step, the first preset distance threshold is used to indicate that the distance is a critical distance for vehicle saf...

Embodiment 2

[0086] Based on the same inventive concept, another embodiment of the present application provides a driving protection device, which is used to execute the driving protection method provided by the first embodiment of the present application; refer to Figure 5 , showing the structural block diagram of the driving protection device of the present application, such as Figure 5 Shown includes:

[0087] The first obtaining module 11 is used to obtain the distance between the obstacle and the vehicle when an obstacle is detected within the preset distance range; the distance between the obstacle and the vehicle may be the distance between the obstacle and the front of the vehicle, or is the distance from the obstacle to the rear of the vehicle.

[0088] The first determination module 12 is configured to trigger a driving protection mode according to the condition that the distance is less than a first preset distance threshold and the accelerator opening of the vehicle is great...

Abstract

The invention provides a driving protection method and device and a vehicle, and belongs to the technical field of automobiles. Comprising the steps that when it is detected that an obstacle exists in a preset distance range, the distance between the obstacle and a vehicle is obtained; under the condition that the distance is smaller than a first preset distance threshold value and the accelerator opening degree of the vehicle is larger than a preset opening degree threshold value, a driving protection mode is triggered; in response to the driving protection mode, controlling the vehicle to stop driving; when the starting signal of the vehicle is detected again, the current collision risk level of the vehicle is determined according to the current gear, the vehicle speed and the distance of the vehicle; and reducing the speed of the vehicle to a preset speed corresponding to the collision risk level according to the collision risk level. By using the driving protection method provided by the invention, when the driving protection condition is met, the driving protection mode is automatically triggered, so that the problem of vehicle collision caused by factors such as too fast starting speed of the vehicle and misjudgment of the distance between the obstacle and the vehicle by a driver is solved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of automobiles, and in particular, to a driving protection method, device, and vehicle. Background technique [0002] At present, the number of cars in our country is increasing, and the space for car parking is limited. When the vehicle stops and then starts, the vehicle collides due to the vehicle's starting speed is too fast, the driver's misjudgment of the distance between the obstacle and the vehicle and other factors. There are more and more accidents, and the existing vehicles are not loaded with automatic protection functions. When the vehicle starts, collision accidents occur frequently. SUMMARY OF THE INVENTION [0003] The embodiment of the present application provides a driving protection method, which aims to solve the problem of vehicle collision caused by factors such as excessive starting speed of the vehicle and the driver's misjudgment of the distance between t...
