Emergency braking smart booster and emergency braking method

Abstract

The invention relates to an emergency braking smart booster and an emergency braking method, and a driver performs a model analysis according to the pedal force borne by a pedal, and when a preset condition is met, an output power of the smart booster is improved so as to generate a high-power braking force for the emergency braking of a vehicle. According to a desired embodiment, the emergency braking method refers to a method that the smart booster generates a braking power. The method comprises an analyzing phase, in which a mode analysis is performed according to the pedal force borne by the pedal, a determination phase, in which whether the analyzed mode meets the preset condition is determined, and a control phase, in which the output power of the smart booster is improved when the preset condition is determined to be met in the determination phase. Even the old, the weak or female drivers do not have enough strength to tread on the braking pedal, the braking performance of the vehicle can be guaranteed through the emergency braking smart booster and the emergency braking method.

Description

technical field [0001] The present invention relates to an emergency intelligent brake booster and an emergency braking method, specifically referring to the mode analysis based on the pedal force applied by the driver to the pedal, and when the pre-set conditions are met, the output power of the intelligent booster is increased, thereby enabling the vehicle to An emergency intelligent brake booster for emergency braking and an emergency braking method. Background technique [0002] Recently, more and more cars have begun to install smart boosters (Smart Booster). The smart booster is an active braking system that uses a motor-based booster to assist in the regenerative braking of the vehicle. [0003] When the driver applies pedal force to the pedal, the pedal simulator produces a pedal feel, and the ECU calculates the required brake pressure based on the stroke sensed by the stroke sensor, and drives the electric motor to control the brake pressure. [0004] That is, whe...

AI Technical Summary

Problems solved by technology

[0005] In the original intelligent booster including electric motor and pedal simulator, there is no mechanical linkage between the pedal force applied by the driver to the brake pedal and the output power of the brake cylinder. In order to make the braking force increase with the increase of the pedal force , the vehicle is equipped with a pedal simulator. In this case, when emergency braking requires a large braking force, the driver cannot form sufficient braking force due to insufficient pedal force.
