Slope slipping preventing system of electric car and work method of slope slipping preventing system

Abstract

The invention discloses a slope slipping preventing system of an electric car and a work method of the slope slipping preventing system.The slope slipping preventing system of the electric car comprises a four-channel anti-lock system, a vehicle control unit, a gear sensor, a motor controller, a motor, an accelerator pedal, a brake pedal, a hand brake switch and a gradient sensor.The accelerator pedal, the brake pedal, the hand brake switch and the gear sensor are all connected with the vehicle control unit through hard wires.The four-channel anti-lock system and the vehicle control unit are connected through a hard wire or CAN wire.The vehicle control unit and the motor controller are connected through a CAN wire.The motor controller and the motor are connected through a hard wire.According to the slope slipping preventing system, the safety coefficient of the whole car can be increased, and the slope slipping danger of the electric car is effectively eliminated.After the electric car gets into the slope slipping preventing mode, An ABS works, the motor and a battery can be effectively protected, the service life of the whole car can be prolonged, energy consumption can be effectively reduced, and driving mileage can be increased.The electric car adapts to the driving habit of a driver and can be safety driven without special operation, and the slope slipping preventing system can be fast put into use in batches.

Description

Technical field: [0001] The invention relates to an electric vehicle slope prevention system and a working method thereof, belonging to the field of electric vehicles. Background technique: [0002] With the shortage of energy and the aggravation of environmental pollution, the emergence of electric vehicles will become a hot spot in the development of automobiles. In recent years, the proportion of electric vehicles has been increasing; The life of the motor, the motor will not maintain the idle speed like the traditional engine; although this technology saves energy consumption, there is a phenomenon of parking on a slope and the car slips back when starting; if the motor is used to stand on a slope, the motor will continue to work and consume energy, reducing the mileage , The motor will stall if it stays on the slope for a long time. [0003] Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art. Invention content: [0004] Th...
