Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

[0024] Traditional commercial vehicles have auxiliary braking or retarding braking systems to ensure that the vehicle's speed is controlled under emergency special conditions and to ensure the safety of the vehicle. For example, devices such as retarders, exhaust brakes, and in-cylinder brakes are arranged on vehicles or engines. Braking solutions used in traditional vehicles include: engine auxiliary braking and retarder braking. Among them, engine auxiliary braking can be divided into two main forms: exhaust braking and in-cylin...

Abstract

The embodiment of the present invention discloses a braking control method, device, equipment and storage medium. The braking control includes: judging whether to intervene in the auxiliary braking in advance based on vehicle information and environmental information; In some cases, a braking acceleration is determined based on the vehicle information and / or environmental information; and a vehicle braking system is controlled to perform a corresponding braking operation based on the braking acceleration. The technical solution of this embodiment uses vehicle information and environmental information to determine whether to intervene in auxiliary braking in advance, so as to realize predictive comprehensive auxiliary braking, which can make up for the insufficiency and hysteresis of active braking, and improve the driving safety of the vehicle.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle control, and in particular, to a braking control method, device, device, and storage medium. Background technique [0002] In recent years, with the increase in the number of vehicles, vehicle safety issues have attracted more and more attention. Among them, collision accidents caused by rear-end collisions account for more than 70% of the total accidents, which not only seriously threatens people's life and property safety, but also for the The safety control of the vehicle is also a great challenge. [0003] Traditional vehicles are equipped with ABS braking system, but due to the influence of large vehicle mass, slippery road surface, weather and other factors, the vehicle cannot realize the braking operation according to the driver's intention under emergency special conditions. Exceeding the braking safety distance will result in a collision. At present, with the rapid...
