Another object of the present invention is to make it can have the stand test of the engine assembly of idle stop/startup function; whole system is tested, with the policing feature of startup/shutdown of checking motor and the work durable reliability of BSG electric machine controller on stand.
For solving the problems of the technologies described above, the technical solution used in the present invention is: change a social system on traditional engine pedestal, substituted generator with the BSG electric machine control system, the AGM battery has substituted common 12V battery, has also increased the clutch pedal signal input system simultaneously.If system can not start by motor, then can come ato unit by traditional starting electrical machinery mode or power measurer.
Described system just can enter idle stop/start-up mode after satisfying the following condition of setting: at first HCU judges earlier whether the SOF of battery is normally, if normally then be shown as " 1 "; And then the temperature of judgement battery, if the temperature of battery is less than 65 degree; Again the motor status of BSG electric machine control system is judged, if the state of motor is normal, the water temperature of motor is greater than 20 degree simultaneously, the function of idle stop/startup is for normally opening, be shown as " 1 ", then can use idle stop/startup function, i.e. the startup of motor can be by electric motor starting, and the idling function of motor can be closed; If do not satisfy above-mentioned condition, the Starter that then adopts power measurer or motor to carry starts;
After starting successfully, rotating speed to motor is judged, when the rotating speed of motor during greater than 300rpm, BSG motor outage this moment, no longer drag engine running, according to traditional E MS (engine control system-Engine management System) strategy, motor begins automatic oil spout running, rotating speed can rise to automatically idling and more than; When the rotating speed of motor during greater than 1000rpm, judge that the aperture of throttle changes, if Δ α＞0, then motor enters accelerating mode; If Δ α＜0, then motor enters decelerating mode; If Δ α=0, then motor is in cruising condition; When the rotating speed of motor during less than 1000rpm, need judge the idle stop state of motor, if normal, be shown as " 1 ", then enter idle stop; Otherwise be exactly to start to lose efficacy, need restart.
Because this motor has idle stop/startup function, both can shut down when idling automatically when motor satisfies condition, when clutch depressed or shift signal is arranged or throttle signal is arranged, motor can start automatically.Shift signal is given the control unit of motor by the I/O mouth of stand, and control unit also can be delivered to parameters such as the electric weight of the electric current of motor, voltage, battery, temperature in the control panel of stand simultaneously, and the working state of motor is monitored.
Compared with prior art; the present invention has following beneficial effect: this motor removes the generator on the conventional engines; change the motor of an approximate size simultaneously into; the function that this motor has generating and drives; behind hot idle stop; can pass through the quick ato unit of driven by motor belt, and can reduce the noise when coming ato unit, can satisfy the needs of various vehicles with traditional Starter.
