Abstract
The utility model discloses a kind of new energy vehicle controller, comprise first, second CAN driver module be connected with outside CAN communication, described first driver module is connected with central control chip communication, described central control chip is connected with Digital I/O, Simulation with I O, PWM module and security control chip communication respectively, described security control chip is connected with described 2nd CAN driver module communication, and the control output end of described security control chip is electrically connected with the control input end of power transfer module.The chip that the utility model advantage is this device to be run as main policies except the central control chip employing Freescale 32, also add the security control chip safe in operation border watchdog routine simultaneously of a Freescale 16, because margin of safety watchdog routine is relatively simple, program robustness is high, and can reset central control chip under certain condition.
Description
Technical field
The utility model relates to new-energy automobile, especially relates to a kind of new energy vehicle controller.
Background technology
In new energy vehicle, general kernel electrocardio Ore-controlling Role primarily of electric machine controller, battery management system and entire car controller three big unit composition.The reliability of three large ECU (Electrical Control Unit) is directly connected to the stable and reliable of vehicle, and the operation of wherein entire car controller burden driver intention parsing, moment of torsion arbitration, car load heat management, fault distinguishing and Security Techniques and realization, need higher reliability.
Summary of the invention
The utility model object is the new energy vehicle controller providing a kind of global reliability high.
For achieving the above object, the utility model can take following technical proposals:
New energy vehicle controller described in the utility model, comprise first, second CAN driver module be connected with outside CAN communication, described first driver module is connected with central control chip communication, described central control chip is connected with Digital I/O, Simulation with I O, PWM module and security control chip communication respectively, described security control chip is connected with described 2nd CAN driver module communication, and the control output end of described security control chip is electrically connected with the control input end of power transfer module.
The chip that the utility model advantage is this device to be run as main policies except the central control chip employing Freescale 32, also add the security control chip safe in operation border watchdog routine simultaneously of a Freescale 16, because margin of safety watchdog routine is relatively simple, program robustness is high, can be resetted central control chip under certain condition, main policies program initial conditions is all set to real-time query mode, being reset of safety can return to correct presence states.The isomerism parallel pattern that two chips adopt, improves overall reliability when realizing sophisticated functions.
Accompanying drawing explanation
Fig. 1 is schematic block circuit diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, new energy vehicle controller described in the utility model, comprise first, second CAN driver module be connected with outside CAN communication, described first driver module is connected with central control chip communication, described central control chip is connected with Digital I/O, Simulation with I O, PWM module and security control chip communication respectively, described security control chip is connected with described 2nd CAN driver module communication, and the control output end of described security control chip is electrically connected with the control input end of power transfer module.
Its principle of work is: central control chip process acceleration pedal is resolved, and driving model differentiates, multiple tasks such as feedback braking torque arithmetic; Respectively for the output of each task in security control chip, setting safety value, whether as in: pedal value zone of reasonableness, whether primary flight pattern conflicts, and in the reasonable scope whether, whether torque exports in zone of reasonableness etc. feedback braking; When security control chip detects that the output valve of certain task of central control chip goes beyond the scope, notice central control chip re-starts this task computation; Certain task repeatedly mis-calculate, security control chip notice central control chip closes the output of this module; When while central control chip and security control chip carry out timing handshake, the left and right of similar hardware watchdog, not shake hands explanation as crossed central control chip time-out, certain task of central control chip exceeds controllable time, and security control chip request central control chip carries out warm reset; As central control chip does not respond any instruction of security control chip, then think that central control chip lost efficacy, then by hardware forced resetting central control chip; Because central control chip runs comparatively sophisticated strategies, the simple and convenient test of security control chip operation procedure, can think that security control chip program reliability is higher, so can the fiduciary level of overall improved system.
