Abstract
The invention relates to an integrated electronic hydraulic braking system capable of actively switching driving styles, and aims at solving the problems of poorer integrated level, complicated structure and failure of achieving the continuous adjustment of boost ratio according to driving styles of a current electronic hydraulic braking system. The system comprises a housing, a first motor, a second motor, a boost motor, a braking main cylinder, a driving wheel, a driven wheel, a transmission belt, a braking pedal push rod, first transmission pairs, second transmission pairs, third transmission pairs, an electric control unit (ECU), a hydraulic control unit (HCU) and a pedal travel sensor, wherein the first motor, the second motor, the boost motor, the braking main cylinder, the electriccontrol unit (ECU) and the hydraulic control unit (HCU) are arranged on the housing. By means of the integrated electronic hydraulic braking system, the continuous adjustment of braking boost ratio isachieved, the boost ratios with any magnitudes can be selected according to the wills of drivers, the free switching of the driving styles is completed, and the system is conformed to the developingtendency of driving style customization in a current intelligent driving technology.
Description
technical field [0001] The invention relates to a braking system, in particular to an integrated electronic hydraulic braking system for actively switching driving styles. Background technique [0002] In recent years, the continuous progress of automobile intelligent technology and electrification technology has put forward higher requirements for the automobile braking system. To charge the battery to increase the cruising range, it can be used as an important underlying actuator of the intelligent driving assistance system, which can realize the arbitrary switching of different driving styles, that is, the brake booster ratio can be adjusted, which can make different drivers change according to their own preferences. driving style. In order to conform to the development trend of automobile intelligence and electrification, the application of traditional vacuum booster braking system is gradually decreasing, and the research on electrohydraulic braking system has become a...
