Abstract

The invention discloses a motor controller for a vehicle and the vehicle. Wherein, the motor controller includes: a first processor, including a first sub-processor, a second sub-processor, a comparator, and a power control unit; the first sub-processor sends a first request signal through a first CAN transceiver; The second subprocessor sends the second request signal through the second CAN transceiver; the first subprocessor reads back the first feedback signal of the first signal through the second CAN transceiver; the second subprocessor transmits the first feedback signal through the first CAN transceiver Read back the second feedback signal of the second signal; the comparator is used to compare the first feedback signal and the second feedback signal to obtain a comparison result; the power control unit is used to determine the fault state of the CAN bus of the motor controller according to the comparison result, wherein, The first request signal and the second request signal are the same. The present invention solves the problem of long fault response time of the controller in the prior art, and realizes the effect of real-time response to the fault of the controller.

Description

technical field [0001] The invention relates to the field of motor control, in particular to a motor controller for a vehicle and the vehicle. Background technique [0002] The controller of the automobile in the prior art uses a dual-chip, which makes the reaction time of the system fault very long, and the controller in the prior art adopts the mode of direct feedback back to the main processor, which increases the system common cause failure; in addition , due to the limited operating voltage range of FAIL SAFE SBC (that is, fail-safe electronic induction braking control system), it cannot meet the needs of compatible use of 12V and 24V systems. [0003] Aiming at the problem of long fault response time of the controller in the prior art, no effective solution has been proposed yet. Contents of the invention [0004] For the problem of long fault response time of the controller in the related art, no effective solution has been proposed so far. Therefore, the main purp...
