Abstract

The invention provides a signal control device and method and a vehicle. The device comprises a processor used for sending out a first bridge arm driving signal and a second bridge arm driving signal,a driving board used for sending out a driving fault signal, and a first level converter and a programmable device that are arranged between the processor and the driving board in parallel; and the second level converter is arranged between the programmable device and the driving board; the first level converter comprises a first enabling end, and the second level converter comprises a second enabling end; when the first enabling end is in an on state, the first bridge arm driving signal is transmitted to the driving board through the first level converter; when the second enabling end is inthe on state, a second bridge arm driving signal is transmitted to the driving board through the programmable device and the second level converter in sequence; and when the processor receives a firstbridge arm fault signal sent by the driving board, the processor or the programmable device controls the first enabling end to be converted into a turn-off state.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a signal control device, method and vehicle. Background technique [0002] With the development of new energy vehicles, the core issue at present is the driving motor technology, that is, the driving technology of the motor controller. In the driving motor technology, the control of the PWM (Pulse Width Modulation; Pulse Width Modulation) signal sent from the MCU (Microcontroller Unit; Microcontroller Unit) is particularly important. [0003] At present, most of the driving motor technology adopts the direct drive type, that is, the PWM signal sent by the MCU is directly transmitted to the driver board. Considering the occurrence of the upper and lower bridge arms through-through, the software dead-time is generally set to avoid the occurrence of the upper and lower bridge arm through-through phenomenon. However, the existing dead time is a preset fixed value, which cannot monit...
