Vehicle running control method and control device

Abstract

The invention provides a vehicle running control method and a control device. The control method comprises the following steps: carrying out real-time monitoring on the distance from a vehicle to a front barrier; judging whether the distance from the vehicle to the front barrier is within the safety distance range or not, and if yes, executing a speed control speed; if not, continuing to monitoring the distance from the vehicle to the front barrier; the speed control step comprises the following steps: acquiring the average speed information of the front barrier and the current accelerator pedal information and the speed information of the vehicle; acquiring the collision avoidance time for the vehicle to avoid the front barrier and the minimum time that the vehicle collides with the front barrier; comparing whether the collision avoidance time is greater than the minimum time of generating collision or not; and if yes, executing a collision avoidance operation. By adopting the control method and the control device, the vehicle can be prevented from colliding with the front barrier, and thereby, the vehicle running safety is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a vehicle driving control method and a vehicle driving control device. Background technique [0002] In recent years, with the rapid development of the automobile industry and the construction of infrastructure, the speed of automobiles on the road is getting faster and faster. Although this makes people's life more convenient, the improvement of automobile speed also increases the probability of traffic accidents, such as rear-end collisions or other collision accidents, causing losses to people's lives and property. The main reason is that the driver's inaccurate judgment of the distance between the obstacle in front (such as a vehicle) and the vehicle he is driving leads to traffic accidents. For example, the distance between the vehicle driven by the driver and the obstacle in front is no longer within the The safe driving distance range, but the driver is still acce...

Although this makes people's lives more convenient, the increase in vehicle speed also increases the probability of traffic accidents, such as rear-end collisions or other collisions, causing losses to people's lives and property

The main reason is that the driver's inaccurate judgment of the distance between the obstacle in front (such as a vehicle) and the vehicle he is driving leads to traffic accidents. For example, the distance between the vehicle driven by the driver and the obstacle in front is no longer within the The safe driving distance range, but the driver is still accelerating due to wrong judgment, resulting in a collision with the vehicle in front; or the driver makes an operation error, such as the driver should take braking measures on the vehicle he is driving, but steps on it by mistake The accelerator pedal causes the vehicle to accelerate, resulting in a collision with the vehicle ahead
