Abstract
The invention discloses a motor control system for an electric vehicle. The motor control system comprises an electronic compass and a motor controller, wherein the electronic compass is communicated with the motor controller; in the riding process of the electric vehicle, the electronic compass is used for measuring the running state of the electric vehicle in the riding process, and transmitting running state information of the electric vehicle to the motor controller; the motor controller is used for adjusting running of an electric vehicle motor according to the running state of the electric vehicle. In the motor control system, the motor controller is taken as the core of the running control of the electric vehicle, and control is performed according to a set optimizing program, so that the running state of the electric vehicle is improved greatly, and the riding comfort is enhanced.
Description
Technical field
The present invention relates to battery-driven car, relate in particular to electric vehicle motor control system.
Background technology
The upper battery-driven car of existing market, its riding condition is manipulated according to the running state of road surface situation and battery-driven car itself by bicyclist completely, due to the difference of bicyclist's perception, manipulate not accurate enoughly, therefore the running state of battery-driven car and the comfort level of riding are all good not.
Summary of the invention
Technical matters to be solved by this invention is just to provide a kind of electric vehicle motor control system, improves the running state of battery-driven car, improves the comfort level of riding.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of electric vehicle motor control system, comprise electronic compass and electric machine controller, described electronic compass is connected with electric machine controller communication, ride in process at battery-driven car, described electronic compass is measured battery-driven car and is transferred to electric machine controller in the running state of the process of riding and by running state of electric motor car information communication, and described electric machine controller is adjusted the operation of electric vehicle motor according to running state of electric motor car.
Preferably, when battery-driven car goes up a slope, motor controller controls motor increases torque, when descending, and motor controller controls decelerating through motor.
Preferably, angle of slope is greater than 30 while spending instantly, and motor controller controls stops outgoing current to motor.
Preferably, according to electric vehicle rotary to angular dimension, motor controller controls decelerating through motor.
Preferably, when battery-driven car tilts or when double swerve, motor controller controls decelerating through motor.
The present invention installs the electronic compass of a perception running state of electric motor car on battery-driven car, and electronic compass is connected with electric machine controller communication, ride in process at battery-driven car, electronic compass is measured battery-driven car and is transferred to electric machine controller in the running state of the process of riding and by running state of electric motor car information communication, electric machine controller is adjusted the operation of electric vehicle motor according to running state of electric motor car, because electronic compass perception running state of electric motor car is more accurate, and the electric machine controller core that operation is controlled as battery-driven car, control according to the optimizer of setting, therefore improve greatly the running state of battery-driven car, improve the comfort level of riding.
Detailed description of the invention
A kind of electric vehicle motor control system, comprise electronic compass and electric machine controller, described electronic compass is connected with electric machine controller communication, ride in process at battery-driven car, described electronic compass is measured battery-driven car and is transferred to electric machine controller in the running state of the process of riding and by running state of electric motor car information communication, and described electric machine controller is adjusted the operation of electric vehicle motor according to running state of electric motor car.When battery-driven car goes up a slope, motor controller controls motor increases torque, when descending, and motor controller controls decelerating through motor.Instantly angle of slope is greater than 30 while spending, and motor controller controls stops outgoing current to motor.According to electric vehicle rotary to angular dimension, motor controller controls decelerating through motor.When battery-driven car tilts or when double swerve, motor controller controls decelerating through motor.
The micro controller system of electronic compass and electric machine controller, by 232 communications, offers micro controller system running state of electric motor car data, and SCM program is adjusted the running state of motor according to data.
Electronic compass is measured battery-driven car state of kinematic motion, and when battery-driven car goes up a slope, motor controller controls motor provides larger torque, with the crossing ability that ensures to go up a slope; When descending, motor controller controls decelerating through motor, angle of slope is greater than 30 while spending instantly, and electric machine controller stops outgoing current to motor.And according to the size of steering angle, motor controller controls decelerating through motor, in the time that battery-driven car tilts with double swerve, motor controller controls decelerating through motor, therefore the present invention can improve the crossing ability that battery-driven car goes up a slope, and descending and inclination, turns to, rocks the driving safety in situation.
