Abstract
The invention discloses a control structure for a master chip and a slave chip and a control method in a new-energy automobile assembly controller. The control structure comprises a master chip and a slave chip, wherein the master chip is provided with an analog quantity input interface, a digital quantity input interface and a digital quantity output interface; the slave chip is provided with a 14-path 12-Bit ADC switching channel, 12-path ePWM output interface, 1-path SPI communication port, 1-path SCI communication port and a 33-path GPIO; the slave chip is connected with the master chip by the SCI communication port and an external hardware watchdog by the SPI communication port. The invention ensures that the assembly controller can operate the minimum control unit to safely limp to return home under the condition that hardware is damaged or a procedure halts.
Description
Technical field
The present invention relates to a kind of principal and subordinate's chip controls structure and control method integrated in the new-energy automobile power assembly controller.
Background technology
Having entered since the new century, is that the energy-saving and environment-friendly automobile of new generation of representative starts an automotive engineering revolution just in the world with hybrid power, pure electronic, fuel cell etc.Power assembly controller wherein is a very important part in the new-energy automobile parts, and the security of new-energy automobile and reliability are the piths that must consider in the power assembly controller research process.But in the prior art, automobile does not have a kind ofly from chip controls circuit or control method under the situation that main control circuit lost efficacy, and makes automobile to travel under the limping state, thus new-energy automobile shortcoming still also aspect security and reliability.
Summary of the invention
In order to solve the problems referred to above that prior art exists, the present invention proposes a kind of principal and subordinate's chip controls structure and the control method in a kind of new-energy automobile assembly controller, for the safety of new-energy automobile in driving procedure provides safeguard, make automobile under the situation that main control loop was lost efficacy, provide minimum control loop, allow the automobile limp-home.
For achieving the above object, the present invention can be achieved by the following technical programs:
Principal and subordinate's chip controls structure in a kind of new-energy automobile assembly controller of the present invention, comprise master chip, it is provided with analog quantity input interface, digital-quantity input interface, digital-quantity output interface, also comprise one from chip, it is provided with 14 road 12-Bit ADC ALT-CH alternate channels, 12 road ePWM output interfaces, 1 road SPI PORT COM, 1 road SCI PORT COM, 33 road GPIO, should be connected by described SPI PORT COM between chip and the described master chip, and be connected by the SPI PORT COM between the external hardware house dog.
The present invention also proposes the principal and subordinate's chip controls method in a kind of new-energy automobile assembly controller, and it may further comprise the steps:
When 1) at first described master chip began operate as normal, it continuously gave described from chip transmission information;
2) when described master chip sends error message by described SCI PORT COM to master chip, that is, when master chip work is undesired, describedly provide a reset signal by described external hardware house dog to master chip from chip;
3) if described master chip still can't operate as normal after resetting, that is described starts working from chip, and the operation of control car load reaches the slope row and goes home.
The present invention has adopted principal and subordinate's chip modulate circuit in power assembly controller ECU.In the master chip operate as normal, all are through the signal of power assembly ECU, comprise that analog quantity is imported (AI), digital quantity is imported (DI), digital quantity output (DO) etc. and all handled by master chip, so the operate as normal of master chip is the basis that automobile is realized maximum function.In case can't restart but master chip damages or program crashes, automobile will not cast anchor because there being control loop.Therefore take place for fear of top situation, some satisfy the travel signal (slope row function) of functional requirement of automobile minimum and not only import master chip, also enter from chip simultaneously, both the quantity of the signal of handling from chip was a subclass of master chip processing signals quantity.Master chip and be the SCI serial communication from what adopt between the chip, in the time of the master chip operate as normal, master chip can continuously be given from chip and send message, show that master chip is working properly.In case master chip work is undesired, message error by the SCI transmission, just provide a reset signal to master chip from chip by hardware watchdog, if master chip still can't operate as normal after resetting, that is just started working from chip, the control car load operation, reach the function that slope row is gone home.
The present invention can make automobile under the situation that main control circuit lost efficacy, and uses a kind ofly from the chip controls circuit, make automobile to travel under the limping state, thereby the raising new-energy automobile is in security and reliability.
Description of drawings
Fig. 1 is a structure conditioning schematic circuit of the present invention.
Fig. 2 is the process flow diagram of the principal and subordinate's chip controls method in a kind of new-energy automobile assembly controller of the present invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
Principal and subordinate's chip controls structure in the new-energy automobile assembly controller of the present invention, as shown in Figure 1, this circuit adopts the 3.3V power supply, comprise master chip, it is provided with analog quantity input interface, digital-quantity input interface, digital-quantity output interface, always has 14 road 12-Bit ADC ALT-CH alternate channels from chip, 12 road ePWM outputs, 1 road Serial Peripheral Interface (SPI) PORT COM, 1 road Serial Communications Interface (SCI) PORT COM, 33 road GPIO.Be connected by the SPI PORT COM between chip and the master chip, be connected by the SPI PORT COM, be the SPI communication between chip and the external hardware house dog.When main control circuit lost efficacy, when SCI communicating interrupt between principal and subordinate's chip or communication are undesired, provide a reset signal from chip by the house dog master chip, if master chip still can't operate as normal after resetting, from chip enable, begin to handle the various information that peripheral circuit transmits, control corresponding circuit, finally realize the function that the safety of walking lamely is gone home.
The present invention also proposes the principal and subordinate's chip controls method in a kind of new-energy automobile assembly controller, and as shown in Figure 2, it may further comprise the steps:
When 1) at first described master chip began operate as normal, it continuously gave described from chip transmission information;
2) when described master chip sends error message by described SCI PORT COM to master chip, that is, when master chip work is undesired, describedly provide a reset signal by described external hardware house dog to master chip from chip;
3) if described master chip still can't operate as normal after resetting, that is described starts working from chip, and the operation of control car load reaches the slope row and goes home.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
