Anti-sliding control system for electric automobile

Abstract

The invention relates to an anti-sliding control system for an electric automobile, which comprises a motor controller, as well as a motor, an accelerator pedal, an accelerator pedal sensor, a brake pedal, a brake pedal sensor, a motor current sensor and a rotary transformer that are all connected with the motor controller; accelerator pedal signals, brake pedal signals, motor current data signals, motor rotating speed data signals, rotating-transforming signals and other data of the motor controller are all collected and processed by a DSP (Digital Signal Processor) data processor; the motor is controlled by the motor controller; the signals are sent to a DSP chip data processor through all sensors, so that ramp conditions for the automobiles can be judged; svpwm (space vector pulse width modulation) duty ratio is adjusted through the controller; driving current is adjusted, so that torque of the automobile borne due to a slope is counteracted by motor driving torque; and the automobiles are prevented from sliding, so that traffic accidents are greatly reduced, and meanwhile the operation burden of starting the automobile again after a driver brakes the automobile during uphill and downhill is reduced.

Description

technical field [0001] The invention relates to a control system for an electric vehicle, in particular to an anti-rolling control system for an electric vehicle, and belongs to the field of braking control systems for an electric vehicle. Background technique [0002] With the gradual improvement of people's living standards, cars have gradually become the means of transportation for people to travel. Moreover, as the concept of low-carbon environmental protection is deeply rooted in the hearts of the people, the market share of electric new energy vehicles has gradually increased and become popular. However, during daily vehicle driving, especially when going up and downhill, it is difficult to restart the vehicle. When the brake pedal is lifted, the vehicle will often slide backwards due to the influence of gravity. Once the driver does not react in time, it will Collide with other vehicles and cause a safety accident. And for some driving novice, this type of accident ...

Problems solved by technology

However, during daily vehicle driving, especially when going up and downhill, it is difficult to restart the vehicle. When the brake pedal is lifted, the vehicle will often slide backwards due to the influence of gravity. Once the driver does not react in time, it will Collision with other vehicles, causing a safety accident

And for some driving novice, this kind of accident happens more frequently, all brings very big injury to people's body and mind
