Vehicle control method and device

Abstract

The present disclosure provides a vehicle control method and device. The vehicle control method includes: acquiring the speed of a second vehicle in front of the first vehicle and the first distance between the first vehicle and the second vehicle; The speed and acceleration of the second vehicle, the speed of the second vehicle and the first distance determine that the first vehicle and the second vehicle are about to collide with each other, determine the first driving parameter of the second vehicle; send the first driving parameter to the second vehicle vehicle, so that the second vehicle is driven according to the first driving parameter. The second vehicle travels according to the minimum driving distance for avoiding rear-end collision, the minimum first acceleration during acceleration, the minimum acceleration time, the minimum second acceleration during deceleration, and the minimum deceleration time, and makes corresponding avoidance actions to avoid collision between the first vehicle and A rear-end collision with a second vehicle occurs.

Description

technical field [0001] The disclosure belongs to the technical field of the Internet of Things, and specifically relates to a vehicle control method and device. Background technique [0002] In reality, rear-end collisions often occur. The first vehicle is behind the second vehicle, but because the driver of the first vehicle is inattentive, or because the braking force of the second vehicle is superior to that of the first vehicle, or because the first vehicle is Failure to maintain a sufficient safe distance, or a combination of the above reasons, led to the rear-end collision of the first vehicle with the second vehicle. [0003] In the prior art, a vehicle rear-end collision prevention control method is disclosed, including: when detecting that there is a following vehicle behind the target vehicle, judging whether there is a collision risk between the following vehicle and the target vehicle; if the following vehicle There is a risk of collision with the target vehicl...

Problems solved by technology

[0004] However, the prior art cannot realize the following functions: the rear vehicle actively informs the front vehicle that a collision is about to occur, and the rear vehicle sends the parameters of acceleration, speed and distance to the front vehicle, so that the front vehicle can transmit parameters according to the acceleration, speed and distance sent by the rear vehicle. Drive according to the parameters and take corresponding avoidance measures
