Embodiment 1
[0077] Attached as the present invention figure 1 Shown, the present invention is a kind of master-slave chip that is used for smart car control assembly, comprises:
[0078] Main chip: There are multiple semaphore input interfaces and command output ports, which are used to process the input semaphore and generate control commands;
[0079] The first slave chip: it is provided with a plurality of semaphore acquisition interfaces, which are used to collect the real-time state quantity of the automobile assembly, and convert the real-time turntable quantity into a semaphore and send it to the semaphore input interface of the main chip;
[0080] The second slave chip: it is provided with a plurality of communication interfaces, which are used to transmit the semaphore received by the master chip to the host computer, and monitor and monitor the output control signal and the input signal quantity of the master chip through the host computer show;
[0081] The third slave chip: ...

[0084] Preferably, the plurality of semaphore input interfaces include: a pulse quantity input interface, an analog quantity input interface, a switch quantity input interface, and an analog voltage quantity input interface; wherein,
[0085] The pulse quantity input interface performs pulse quantity conversion through a Hall sensor;
[0086] The analog quantity input interface performs analog quantity conversion through the electric displacement sensor;
[0087] The switching value input interface performs switching value conversion through a node switch;
[0088] The analog voltage quantity is converted to analog voltage by a relay.
[0089] The principle of the above-mentioned technical solution is: the present invention comprises a plurality of input quantity interfaces and a plurality of instruction output ports; The driving speed of the car, or the real-time temperature of the car is obtained through the temperature sensor. The temperature signal can be converted from ...
Embodiment 3
[0092] Preferably, the signal quantity output interface includes a vehicle speed control port, an accelerator pedal control port, a brake pedal sensing port, an electronic throttle position sensing port, a brake pedal zero position signal port, a key switch port, and a start signal port , mode switch port, engine control port; among them,
[0093] Engine control ports include: front motor start port and rear motor start port.
[0094] The principle of the above technical solution is that the present invention provides a variety of control instruction input ports, mainly to ensure the comprehensiveness of the control signal, and the output of the instruction can also be controlled through the control signal output of the main chip. In the prior art, because it is mainly an integrated component, there may be interference when the command is output, so it is set
[0095] The beneficial effect of the above-mentioned technical solution is that: by setting multiple control interfac...
