A multi-functional brake-by-wire energy recovery auxiliary system and its control method

Abstract

The invention discloses a multifunctional brake-by-wire energy recovery auxiliary system and a control method thereof, comprising: an accelerator pedal, an accelerator pedal pressure sensor, a vehicle speed sensor, a brake pedal, a brake pedal pressure sensor, and an electronic hydraulic auxiliary braking system Assembly, plunger pump clutch device and main controller; the system of the present invention has the advantages of compact structure and high space utilization rate. It has the function of auxiliary braking, and can also perform energy recovery during auxiliary braking, which is safe and economical, and can reduce the quality of the vehicle and improve the use space of the vehicle.

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...
