Abstract
The utility model discloses a controller with a soft and hard start function for an electric car. The controller is connected with a battery through a switch voltage stabilizing power source, controls a motor to rotate through a power driving module inside the controller, receives a speed regulation signal input from the outside, and receives a speed feedback signal of the motor. The inside of the controller is further provided with a comparison module and a parameter control module. The comparison is used for comparing the preset value and the motor acceleration value collected by a collection module, and outputting the comparison result to the parameter control module. The parameter control module is used for outputting motor control parameters and conducing current-limiting or normal operation according to the output signal of the comparison module. When the controller detects the acceleration of the motor speed of the electric car, the controller compares the detected acceleration value and the detected preset value in the module, and if the preset condition is met, parameter adjustment is conducted on the corresponding procedure to improve the start performance of the electric car.
Description
Technical field
The utility model relates to a kind of electric vehicle soft or hard start-up performance controller.
Background technology
Along with the large-scale popularization of battery-driven car, market is more and more higher to the requirement of battery-driven car comfort level, causes controller more and more accurate with mating of motor; , in technology, the Starting mode of battery-driven car is not made to suitable adjustment now; Relatively acceleration/accel output parameter value are known prior art.
Summary of the invention
The utility model object is the defect for prior art, provides a kind of by control battery-driven car startability according to acceleration/accel.
The utility model for achieving the above object, adopt following technical scheme: a kind of electric vehicle soft or hard start-up performance controller, be connected with battery by switching power supply, by its inner power driver module control electric machine rotation, receive the speed-regulating signal of outside input, the feedback speed signal that simultaneously receives motor, is characterized in that: described controller inside is also provided with comparison module and parameter control module; Described comparison module is used for the motor acceleration value of preset value and signal acquisition module collection to compare, and comparative result is exported to parameter control module; Described parameter control module is used for output motor control parameter, and according to comparison module output signal, carries out current limliting or normally work.
The beneficial effects of the utility model: detect electric vehicle motor rotating speed acceleration/accel by controller, and according to detecting that the preset value in acceleration/accel and module compares, as reach predetermined condition and will adjust parameter by corresponding program, to improve the startability of battery-driven car.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Detailed description of the invention
A kind of electric vehicle soft or hard start-up performance controller as shown in Figure 1, be connected with battery by switching power supply, by its inner power driver module control electric machine rotation, receive the speed-regulating signal of outside input, receive the feedback speed signal of motor, described controller inside is also provided with comparison module and parameter control module simultaneously; Described comparison module is used for the motor acceleration value of preset value and signal acquisition module collection to compare, and comparative result is exported to parameter control module; Described parameter control module is used for output motor control parameter, and according to comparison module output signal, carries out current limliting or normally work.
When work, external battery-unit converts 5V voltage to after switching power supply unit carries out voltage modulated, and is respectively microprocessor control unit, the power supply of multichannel power drive unit.After microprocessor control unit powers on, signal acquisition module acceleration A 1 in the upper electro-detection microprocessor control unit of controller MCU, sends A1 into comparison module, is built-in with default accekeration A0 in comparison module, and A1 and A0 are compared.If when acceleration A 1 is less than preset value A0, cancel the processing that controller is started to cut-off current I; If when acceleration A 1 is more than or equal to preset value A0, continues that controller is started to cut-off current I and process, and then regulate the acceleration/accel of battery-driven car, to reach the startability of adjusting battery-driven car.
