Description

technical field

[0001] The invention belongs to the technical field of automobile brake systems, and specifically refers to a multi-function brake-by-wire energy recovery auxiliary system and a control method thereof. Background technique

[0002] Affected by the oil crisis and frequent traffic accidents, people pay more and more attention to fuel economy and driving safety of cars, and the vehicle braking system is very important to driving safety and energy consumption of cars; existing family cars The brake system usually only has a service brake system and a parking brake system. Usually, a cross-pipeline arrangement is used for the service brake system to improve the driving safety of the car. The auxiliary brake system is generally used on heavy vehicles, and the energy recovery The system is generally used in new energy vehicles.

[0003] Among the existing auxiliary braking technologies, the Chinese invention patent application number is CN201310087512.1, which disc...
