Definitions
- the present invention relates to a control device for an electric vehicle that drives an electric motor by an inverter using a vector control, and more particularly to a torque control for detecting slipping and gliding occurring between wheels and a track surface and re-adhering the same. It relates to the control device of the electric car to be performed. Background art
- Japanese Patent Application Laid-Open No. 4-197004 discloses a method of detecting idling or sliding of wheels of an electric vehicle, reducing the generated torque of an electric motor, and performing re-adhesion control.
- a method for detecting that the wheel has re-adhered is described in Japanese Patent Application Laid-Open No. Hei 4-69003.
- a technique for driving an electric motor for driving an electric vehicle for a railway vehicle by vector control of an inverter is described in Japanese Patent Application Laid-Open No. 5-83976.
- the idling detection method detects a constant value of the time change rate (differential value) of the rotor frequency (in proportion to the wheel speed) of the induction motor. Recognition is made based on whether or not the level has been exceeded, and control is performed to reduce the motor torque only during the period when idling is recognized.
- the differential value becomes smaller than the specified value, the recognition of slip is released, and control is performed to return the motor torque regardless of whether or not the wheels actually re-adhesive. Has the problem that the wheel slips quickly and the slip phenomenon occurs frequently and repeatedly.
- Japanese Patent Application Laid-Open No. 4-69003 discloses that the re-adhesion is detected and the torque is detected. Control is described, and a method of detecting re-adhesion will be described with reference to FIG. It detects slip at time t 1, and then restarts at time t 2 when the second derivative fr ⁇ (shaft jerk value) of the rotor frequency fr (proportional to the wheel speed) exceeds a predetermined value Le. Detects sticking.
- An object of the present invention is to utilize the high-speed torque response of the vector control to effectively utilize the torque up to the physical adhesion limit and to increase the acceleration / deceleration of the electric vehicle as much as possible even in a situation where the adhesion coefficient is low.
- the purpose is to provide control devices for electric vehicles. Disclosure of the invention
- the present invention relates to an electric vehicle that controls a motor that drives wheels of an electric vehicle by a vector control inverter that divides a primary current of the electric motor into an excitation current component and a torque current component and controls them based on command values corresponding to the respective components.
- Means for detecting the wheel speed including the rotor frequency of the motor proportional to the wheel speed), and detecting wheel slip and gliding based on the differential value (time change rate) of the detected wheel speed.
- the differential value of the wheel speed exceeds a predetermined value while the electric vehicle is accelerating, it is regarded as idling and control to reduce the torque current is performed. Begins to accelerate. This re-adhesion point is found from the point where the differential value of the wheel speed becomes negative and the differential value twice becomes positive. As a result, it can be seen that the wheel slip was surely directed to the convergence direction and re-adhesive, and acceleration started again. The torque current continues to be reduced until re-adhesion, and by reliably detecting the re-adhesion, even if the torque current is quickly returned after re-adhesion, the possibility of re-slip is low, and the torque is increased accordingly. It can increase the acceleration of electric vehicles.
- the amount of torque reduction is reduced by reducing the amount of reduction of the torque current because idling is converging. Can be reduced, and the acceleration can be increased accordingly.
- the principle is exactly the same when a gliding occurs when the electric vehicle is decelerating, except for the sign of the detection level, which is different from the case of the idling. In this way, when the motor that drives the wheels is controlled in a vector, the torque current component in the primary current of the motor can be adjusted independently, and the control of the torque current affects only the leakage impedance of the motor. The time constant is small and the control response is fast.

Therefore, when re-adhesion occurs, the output of AND circuit 94 will be
- the output value of 36 becomes the eclipse value in the subtractor 1 13 and is input to the integrator with limiter 43 to reduce the torque current control amount ⁇ I q and restore the torque of the induction motor.
- fr'24 will momentarily become a large value, such as when a rail joint or a point passes, and the output of the comparator 70 will momentarily become "1" and be held by the idling signal 26 "1".
- the setting time of the on-delay 88 can be shortened to about several hundred ms, and even if slipping is erroneously detected, re-adhesion is immediately detected. As a result, it is possible to minimize the decrease in torque utilization. If a gliding occurs during braking, the gliding is detected by the gliding detection unit 10, and the torque current control amount ⁇ I qp is calculated in the same manner as in the case of idling.
- the embodiment shown in FIG. 9 is different from the first in that there are a plurality of control units of the induction motor and that a function generator and a torque current return amount calculator are provided for each of the slipping and the sliding.
- the present invention is most suitable for use in controlling electric vehicles of railways where slipping and gliding frequently occur. However, it is also suitable for electric vehicles if the scope of application of the invention is further expanded.
