Vehicle auxiliary braking method, device, system and terminal

Abstract

The invention discloses a vehicle auxiliary braking method, device, system and terminal. The method comprises the following steps of: acquiring running information of a vehicle and a first target obstacle in front of the vehicle; acquiring running information of the first target obstacle, and a distance and a relative speed between the vehicle and the first target obstacle; calculating the time required by the collision of the vehicle and the first target obstacle according to the distance and the relative speed; determining a current risk level of a collision risk between the vehicle and thefirst target obstacle and a current braking strategy corresponding to the current risk level according to the running information of the vehicle, the running information of the first target obstacle and the time; and responding to an auxiliary control trigger instruction, and controlling a brake system of the vehicle to execute braking operation based on the current braking strategy correspondingto the current risk level. The vehicle auxiliary braking method, device, system and terminal provided by the invention control the vehicle according to the collision risk level of the vehicle and thefirst target obstacle, and ensure the effectiveness and timeliness of the braking.

Description

technical field [0001] The present invention relates to the technical field of vehicle auxiliary braking, in particular to a vehicle auxiliary braking method, device, system and terminal. Background technique [0002] As a common operation in the driving process, braking is of great significance for ensuring the safety of drivers and passengers during driving and reducing the harm caused to drivers and passengers due to unsafe driving behaviors. However, for large vehicles such as heavy-duty trucks with large tonnage and large load, the timeliness and effectiveness of braking are crucial to ensure the driving safety of themselves and other traffic participants. At present, the braking behavior of transportation vehicles such as heavy trucks is still mainly based on the active intervention of the driver (such as stepping on the brake pedal), with electronic or mechanical braking mechanisms (such as: Electronic Stability Control (ESC), braking The anti-lock braking system (AB...

Problems solved by technology

At present, the braking behavior of transportation vehicles such as heavy trucks is still mainly based on the active intervention of the driver (such as stepping on the brake pedal), with electronic or mechanical braking mechanisms (such as: Electronic Stability Control (ESC), braking The anti-lock braking system (ABS), electronically controlled braking system (EBS), etc.) realize the deceleration or stop of the vehicle, so the judgment of the safe driving distance, the timeliness and effectiveness of the braking operation are easily affected by the driver's subjective Influenced by habits, it is less effective in dealing with sudden situations that require braking
