According to an aspect of the present invention, said main motor is an AC induction motor.
According to another aspect of the present invention, said assisted power steering system is a hydraulic power-assisted steering mechanism.
Description of drawings
Fig. 1 is the pure electric-powered system schematic of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing power system of the present invention and type of drive are done and to be described in further detail:
Pure electric coach power assembly system as shown in Figure 1, the 1st, entire car controller, the 2nd, main electric machine controller, the 3rd, main motor, the 4th, servo-steering electric machine controller, the 5th, hydraulic gear, the 6th, steer motor, the 7th, car speed sensor, the 8th, wheel.
Entire car controller 1 is connected with main electric machine controller 2 communications; Entire car controller 1 is responsible for sending and receive throttle analog signal and feedback signal to main electric machine controller 2; Main electric machine controller 2 is connected with vehicle master motor 3 power, and main electric machine controller 1 passes to main motor 2 after throttle signal is handled, in order to drive wheels 8; Main motor 2 feeds back to main electric machine controller with relevant informations such as rotating speed, torques, feeds back to entire car controller after being handled by main electric machine controller.
Can be used for each mode of operation such as vehicle launch, acceleration, deceleration, braking with upper type.
The servo-steering machine controller links to each other with hydraulic gear 5 on the one hand, and the detective liquid force value judges whether vehicle is in steering situation, and control steer motor 6 is handled handling maneuver; Link to each other with car speed sensor 7 on the other hand, detect GES, judge to offer Vehicular turn power-assisted size.Entire car controller 1 is connected with 4 communications of servo-steering machine controller; When the steering box et out of order; Send failure message by steering box controller 4 to entire car controller 1; By 1 pair of trouble diagnosing classification of entire car controller, send the order of the adjustment speed of a motor vehicle automatically according to the fail safe rank, make the speed of a motor vehicle reach safe range.
The mode of operation of power system of the present invention is following:
On the one hand, when vehicle need start, after entire car controller and other each Parts Controller self check are accomplished; Send throttle control signal by entire car controller to main electric machine controller; Main electric machine controller receives throttle control signal and handles later on, passes to main motor, and then powered vehicle.Specifically; When the user when entire car controller input " accelerations " is ordered; Entire car controller is through throttle signal analogous circuit simulation signal for "faster" of water ski signaling; And " acceleration " control signal sent to main electric machine controller, and main electric machine controller receives and passes to main motor after control signal that entire car controller sends is handled, and main motor is according to the control order drive wheels; Main electromechanical transducer passes to main electric machine controller with motor status like rotating speed, torque etc., passes to entire car controller after being handled by main electric machine controller, after entire car controller is handled, is presented at the terminal demonstration and is provided with.This kind mode can realize the purpose that vehicle quickens, slows down, stops.
If motor breaks down, by electric machine controller breakdown signal is sent to entire car controller, entire car controller is made corresponding adjustment according to the failure condition hierarchical processing according to level of security, guarantees vehicle and rider's safety.
Main motor can be the drive motor that suitable electronlmobil such as AC induction motor, AC induction motor, ac synchronous motor, permagnetic synchronous motor and switched reluctance machines uses, preferably AC induction motor in this power system.
