A new energy vehicle triple braking safety protection system and method

Abstract

The invention discloses a triple-braking safety protection system and method for a new energy vehicle. The system includes a GPS speed monitoring system, a video monitoring system and a driving behavior analysis module. The GPS speed monitoring system and the video monitoring system are connected with the input end of the driving behavior analysis module, and the output end of the driving behavioranalysis module is connected with the input ends of a brake pedal, an emergency brake switch and a foot brake switch. The output end of the brake pedal is connected with a vehicle control unit, the output end of the emergency brake switch is connected with an emergency brake valve, and the output end of the foot brake switch is connected with a motor controller. According to the triple-braking safety protection system and method, driving behavior related information transmitted by the GPS speed monitoring system and the video monitoring system is analyzed through the driving behavior analysismodule, to obtain a driving intention of a driver. A strategy provided by the triple-braking safety protection system and method can achieve a triple-braking safety protection function of the new energy vehicle, which is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of brake safety protection systems, and in particular relates to a new energy vehicle triple brake safety protection system and method. Background technique [0002] Under the guidance of relevant national policies, more and more new energy vehicle products have entered the consumer field, and the safety of new energy vehicles cannot be ignored. At present, the braking system of new energy vehicles is generally divided into regenerative braking and pressure braking. Pressure braking is consistent with traditional braking, but regenerative braking is generally issued by the vehicle controller and executed by the motor controller. System errors or misjudgments may occur, so it is necessary to develop a multiple braking safety protection strategy to ensure safe and reliable driving. Contents of the invention [0003] The purpose of the present invention is to provide a new energy vehicle triple braking safet...
