acc vehicle speed control method, device, acc controller, storage medium and vehicle

Abstract

The present invention relates to an ACC vehicle speed control method, device, ACC controller, storage medium and vehicle. The method includes: determining the following distance between the vehicle and the preceding vehicle based on the current vehicle speed of the vehicle and the ACC following time distance under the current vehicle speed. Vehicle distance; the following distance includes several target areas, and each target area sets a different speed acceleration control strategy; obtains the actual distance between the own car and the target car, and the target car is a vehicle in the side lane that cuts into the front lane of the own car , according to the obtained actual distance, it is determined that the actual distance is located in the corresponding target area, and the ego vehicle selects the corresponding vehicle speed acceleration control strategy. The ACC system of the self-vehicle compares the obtained actual distance with the following distance, determines that the actual distance is in the corresponding target area, and then adopts the corresponding self-vehicle speed control strategy to achieve reasonable and dynamic control of the self-vehicle speed, which can avoid giving Members cause extreme discomfort, but also avoid prone to accidents and other phenomena.

Description

technical field [0001] The present invention relates to the technical field of unmanned driving, in particular to an ACC vehicle speed control method and device, an ACC controller, a storage medium and a vehicle. Background technique [0002] Adaptive cruise control (ACC), also known as active cruise, is an intelligent automatic control system. The adaptive cruise system replaces the driver to control the speed of the vehicle, avoiding frequent cancellation and setting of cruise control, making the cruise system suitable for more More road conditions provide drivers with a more relaxed driving method. ACC usually follows the vehicle according to the time distance. When the target vehicle cuts into the front of the own vehicle's lane at a short distance, the speed control of the own vehicle will overshoot, causing extreme discomfort to the occupants, and even prone to accidents. Contents of the invention [0003] (1) Purpose of the invention [0004] The technical problem...
