Problems solved by technology

[0003] The current anti-rear-collision devices for vehicles generally monitor the distance between other vehicles in the direction of travel through cameras to prevent rear-end collisions between their own vehicles and other vehicles in the direction of travel. However, in heavy fog or rainy weather, due to the perspective It is relatively blurred, so the driver cannot see the distance ahead, and the rear-end collision accident is caused by a mistake in judging the distance; See the flashing lights in time, so the driver who reacts too slowly will cause a rear-end collision with the vehicle in front due to the lack of braking in time
The current anti-rear-collision device is relatively simple, so it cannot provide safer and more reliable anti-rear-collision measures

Embodiment 1

[0063] This embodiment provides a vehicle control method, which is used in the control system of the vehicle to perform safety control in the running state of the vehicle, such as figure 1 As shown, the method includes the following steps:

[0064] S11. Obtain the current driving speed of the vehicle and the first distance from other vehicles in the current driving direction. During the running of the vehicle, the running speed of the vehicle can be obtained through the rotational speed of the engine, and the current driving speed can also be detected through the speed sensor. Set a distance sensor at the front or rear of the car, and use the distance sensor to obtain the distance from the vehicle in front or behind. If the vehicle is driving forward, the distance of other vehicles in front of it will be obtained; if the vehicle is driving backward, the distance behind the vehicle will be obtained. The distance of other vehicles in , as the first distance.

[0065] S12. Calcul...

Embodiment 2

[0080] This embodiment provides a vehicle control device corresponding to the vehicle control method, such as Figure 4 As shown, it includes the following units:

[0081] The acquisition unit 41 is configured to acquire the current driving speed of the vehicle and the first distance from other vehicles in the current driving direction.

[0082] The calculation unit 42 is configured to calculate the second distance required for braking according to the driving speed.

[0083] The judging unit 43 is configured to judge whether the second distance is smaller than the first distance, and if the second distance is not smaller than the first distance, perform safety control.

[0084] As an optional implementation, the vehicle control device in this embodiment, such as Figure 5 As shown, the computing unit 42 includes:

[0085] The first acquiring module 421 is configured to acquire the reaction time.

[0086] The first calculation module 422 is configured to calculate the reac...

Embodiment 3

[0099] This embodiment provides a vehicle, and the vehicle control method in Embodiment 1 is applied, including:

[0100] A distance sensor, set at the front of the vehicle or in the parking space, is used to measure the distance from other vehicles in the direction of travel;

[0101] Specifically, the distance sensor uses the principle of the time-of-flight method to measure the distance, that is, a sensor that detects the distance of an object by emitting a particularly short light pulse and measuring the time from when the light pulse is emitted to when it is reflected back. Installing the distance sensor on the vehicle can effectively measure the distance to other vehicles in the same driving direction, and as a safety reference value for the second distance, the driver can drive safely.

[0102] The vehicle control device in Embodiment 2 is used for vehicle control.

[0103] Specifically, through all the devices controlled by the vehicle, the operation of safety control...

Abstract

The invention discloses a vehicle control method and device, and a vehicle. The vehicle control method comprises the following steps that the current traveling speed of the vehicle and a first distance between the vehicle and another vehicle in the current traveling direction are obtained; a second distance required by braking is calculated according to the traveling speed; whether the second distance is smaller than the first distance or not is judged; and if the second distance is not smaller than the first distance, safety control is executed. The reaction distance of a driver and the brakedistance are calculated and compared with the detected safety distance, whether the distance between the vehicle and the another vehicle in the same traveling direction is excessively small or not isjudged, safety measures are adopted accordingly to avoid rear-end accidents, the life safety of the driver can be effectively guaranteed, and the driver can travel safely.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a vehicle control method and device and a vehicle. Background technique [0002] The vehicle control system is to ensure that the vehicle maintains a certain safe distance from other vehicles in the current driving direction, and prevents rear-end collisions with other vehicles, such as collision and friction, so as to ensure the safety of the driver. [0003] The current anti-rear-collision devices for vehicles generally monitor the distance between other vehicles in the direction of travel through cameras to prevent rear-end collisions between their own vehicles and other vehicles in the direction of travel. However, in heavy fog or rainy weather, due to the perspective It is relatively blurred, so the driver cannot see the distance ahead clearly, and the rear-end collision accident is caused by a mistake in judging the distance; See the flashing lights in time, so the ...
